before configuring and building sudo. You may also wish to read the
file INSTALL.configure which explains more about the `configure' script.
+System requirements
+===================
+
+To build sudo from the source distribution you need a POSIX-compliant
+operating system (any modern version of BSD, Linux or Unix should work),
+an ANSI/ISO C compiler that supports the "long long" type, variadic
+macros (a C99 feature) as well as the ar, make and ranlib utilities.
+
+If you wish to modify the parser then you will need flex version
+2.5.2 or later and either bison or byacc (sudo comes with a
+pre-generated parser). You'll also have to run configure with the
+--with-devel option or pass DEVEL=1 to make. You can get flex from
+http://flex.sourceforge.net/. You can get GNU bison from
+ftp://ftp.gnu.org/pub/gnu/bison/ or any GNU mirror.

-Special features/options:
--with-incpath=DIR
Adds the specified directory (or directories) to CPPFLAGS
so configure and the compiler will look there for include
files. Multiple directories may be specified as long as

Adds the specified directory (or directories) to LDFLAGS
so configure and the compiler will look there for libraries.
Multiple directories may be specified as with --with-incpath.
- --with-rpath
- Tells configure to use -Rpath in addition to -Lpath when
- passing library paths to the loader. This option is on
- by default for Solaris and SVR4.
-
- --with-blibpath[=PATH]
- Tells configure to construct a -blibpath argument to the
- loader. If a PATH is specified, it will be used as the
- base. Otherwise, "/usr/lib:/lib:/usr/local/lib" will be
- used for gcc and "/usr/lib:/lib" for non-gcc. Additional
- library paths will be appended as needed by configure.
- This option is only valid for AIX where it is on by default.

- Enable SecurID support. If specified, DIR is directory containing
- sdiclient.a, sdi_athd.h, sdconf.h, and sdacmvls.h.
+ --with-libtool=PATH
+ By default, sudo will use the included version of libtool
+ to build shared libraries. The --with-libtool option can
+ be used to specify a different version of libtool to use.
+ The special values "system" and "builtin" can be used in
+ place of a path to denote the default system libtool (obtained
+ via the user's PATH) and the default libtool that comes
+ with sudo.
- --with-fwtk[=DIR]
- Enable TIS Firewall Toolkit (FWTK) 'authsrv' support. If specified,
- DIR is the base directory containing the compiled FWTK package
- (or at least the library and header files).
+Optional features:

+ With this option, sudo will run the mailer as the invoking
+ user which some people consider to be safer.
- --with-kerb4[=DIR]
- Enable Kerberos IV support. If specified, DIR is the base
- directory containing the Kerberos IV include and lib dirs.
- This uses Kerberos passphrases for authentication but does
- not use the Kerberos cookie scheme.
+ --enable-nls[=location]
+ Enable natural language support using the gettext() family
+ of functions. If specified, location is the base directory
+ containing the libintl include and lib directories. If

+ first, then check for a standalone libintl (linking with
+ libiconv as needed).
- --with-kerb5[=DIR]
- Enable Kerberos V support. If specified, DIR is the base
- directory containing the Kerberos V include and lib dirs.
- This This uses Kerberos passphrases for authentication but
- does not use the Kerberos cookie scheme. Will not work for
- Kerberos V older than version 1.1.
+ --disable-nls
+ Disable natural language support. By default, sudo will
+ use the gettext() family of functions, if available, to
+ implement messages in the invoking user's native language.
+ Note that translations do not exist for all languages.
--with-ldap[=DIR]
Enable LDAP support. If specified, DIR is the base directory
this file instead of /etc/ldap.secret to read the secret password
when rootbinddn is specified in the ldap config file.
- --with-nsswitch[=PATH]
- Path to nsswitch.conf or "no" to disable nsswitch support.
- If specified, sudo uses this file instead of /etc/nsswitch.conf.
- If nsswitch is disabled but LDAP is enabled, sudo will check
- LDAP first, then the sudoers file.
+ --with-logincap
+ This adds support for login classes specified in /etc/login.conf.
+ It is enabled by default on BSD/OS, Darwin, FreeBSD, OpenBSD and
+ NetBSD (where available). By default, a login class is not applied
+ unless the 'use_loginclass' option is defined in sudoers or the user
+ specifies a class on the command line.
+
+ --with-interfaces=no, --without-interfaces
+ This option keeps sudo from trying to glean the ip address
+ from each attached Ethernet interface. It is only useful
+ on a machine where sudo's interface reading support does
+ not work, which may be the case on some SysV-based OS's
+ using STREAMS.
+
+ --with-noexec[=PATH]
+ Enable support for the "noexec" functionality which prevents
+ a dynamically-linked program being run by sudo from executing
+ another program (think shell escapes). Please see the
+ "PREVENTING SHELL ESCAPES" section in the sudoers man page
+ for details. If specified, PATH should be a fully qualified
+ path name, e.g. /usr/local/libexec/sudo_noexec.so. If PATH
+ is "no", noexec support will not be compiled in. The default
+ is to compile noexec support if libtool supports building
+ shared objects on your OS.
+
+ --with-selinux
+ Enable support for role based access control (RBAC) on
+ systems that support SELinux.
+
+ --with-sssd

+ where it is broken (none currently known).
+
+ --enable-admin-flag
+ Enable the creation of an Ubuntu-style admin flag file
+ the first time sudo is run.
+
+ --with-bsm-audit
+ Enable support for sudo BSM audit logs on systems that support it.
+ This includes recent versions of FreeBSD, Mac OS X and Solaris.
+
+ --with-linux-audit
+ Enable audit support for Linux systems. Audits attempts
+ to run a command as well as SELinux role changes.
+
+ --with-man
+ Use the "man" macros for manual pages. By default, mdoc versions
+ of the manuals are installed if supported. This can be used to

+ Sudoers option: !env_reset
- --with-long-otp-prompt
- When validating with a One Time Password scheme (S/Key or
- OPIE), a two-line prompt is used to make it easier to cut
- and paste the challenge to a local window. It's not as
- pretty as the default but some people find it more convenient.
+ --disable-path-info
+ Normally, sudo will tell the user when a command could not be found
+ in their $PATH. Some sites may wish to disable this as it could
+ be used to gather information on the location of executables that
+ the normal user does not have access to. The disadvantage is that
+ if the executable is simply not in the user's path, sudo will tell
+ the user that they are not allowed to run it, which can be confusing.
+ Sudoers option: path_info
- --with-logging=TYPE
- How you want to do your logging. You may choose "syslog",
- "file", or "both". Setting this to "syslog" is nice because
- you can keep all of your sudo logs in one place (see the
- sample.syslog.conf file). The default is "syslog".
+ --disable-root-sudo
+ Don't let root run sudo. This can be used to prevent people from
+ "chaining" sudo commands to get a root shell by doing something
+ like "sudo sudo /bin/sh".
+ Sudoers option: !root_sudo
- --with-logfac=FACILITY
- Determines which syslog facility to log to. This requires
- a 4.3BSD or later version of syslog. You can still set
- this for ancient syslogs but it will have no effect. The
- following facilities are supported: authpriv (if your OS
- supports it), auth, daemon, user, local0, local1, local2,
- local3, local4, local5, local6, and local7.
+ --disable-zlib
+ Disable the use of the zlib compress library when storing
+ I/O log files.
+ Sudoers option: !compress_io
- --with-goodpri=PRIORITY
- Determines which syslog priority to log successfully
- authenticated commands. The following priorities are
- supported: alert, crit, debug, emerg, err, info, notice,
- and warning.
+ --enable-log-host
+ Log the hostname in the log file.
+ Sudoers option: log_host
- --with-badpri=PRIORITY
- Determines which syslog priority to log unauthenticated
- commands and errors. The following priorities are supported:
- alert, crit, debug, emerg, err, info, notice, and warning.
+ --enable-noargs-shell
+ If sudo is invoked with no arguments it acts as if the "-s" flag had
+ been given. That is, it runs a shell as root (the shell is determined
+ by the SHELL environment variable, falling back on the shell listed
+ in the invoking user's /etc/passwd entry).
+ Sudoers option: shell_noargs
- --with-logpath=PATH
- Override the default location of the sudo log file and use
- "path" instead. By default will use /var/log/sudo.log if
- there is a /var/log dir, falling back to /var/adm/sudo.log
- or /usr/adm/sudo.log if not.
+ --enable-shell-sets-home
+ If sudo is invoked with the "-s" flag the HOME environment variable
+ will be set to the home directory of the target user (which is root
+ unless the "-u" option is used). This option effectively makes the
+ "-s" flag imply "-H".
+ Sudoers option: set_home
- --with-loglen=NUMBER
- Number of characters per line for the file log. This is only used if
- you are to "file" or "both". This value is used to decide when to wrap
- lines for nicer log files. The default is 80. Setting this to 0
- will disable the wrapping.
+ --with-all-insults
+ Include all the insult sets listed below. You must either specify
+ --with-insults or enable insults in the sudoers file for this to
+ have any effect.
- --with-ignore-dot
- If set, sudo will ignore '.' or '' (current dir) in $PATH.
- The $PATH itself is not modified.
+ --with-askpass=PATH
+ Set PATH as the "askpass" program to use when no tty is
+ available. Typically, this is a graphical password prompter,
+ similar to the one used by ssh. The program must take a
+ prompt as an argument and print the received password to
+ the standard output. This value may overridden at run-time
+ in the sudo.conf file.
- --with-mailto=USER|MAIL_ALIAS
- User (or mail alias) that mail from sudo is sent to.
- This should go to a sysadmin at your site. The default is "root".
+ --with-badpass-message="BAD PASSWORD MESSAGE"
+ Message that is displayed if a user enters an incorrect password.
+ The default is "Sorry, try again." unless insults are turned on.
+ Sudoers option: badpass_message
- --with-mailsubject="SUBJECT OF MAIL"
- Subject of the mail sent to the "mailto" user. The token "%h"
- will expand to the hostname of the machine.
- Default is "*** SECURITY information for %h ***".
+ --with-badpri=PRIORITY
+ Determines which syslog priority to log unauthenticated
+ commands and errors. The following priorities are supported:
+ alert, crit, debug, emerg, err, info, notice, and warning.
+ Sudoers option: syslog_badpri
- --without-mail-if-no-user
- Normally, sudo will mail to the "alertmail" user if the user invoking
- sudo is not in the sudoers file. This option disables that behavior.
+ --with-classic-insults
+ Uses insults from sudo "classic." If you just specify --with-insults
+ you will get the classic and CSOps insults. This is on by default if
+ --with-insults is given.
- --with-mail-if-no-host
- Send mail to the "alermail" user if the user exists in the sudoers
- file, but is not allowed to run commands on the current host.
+ --with-csops-insults
+ Insults the user with an extra set of insults (some quotes, some
+ original) from a sysadmin group at CU (CSOps). You must specify
+ --with-insults as well for this to have any effect. This is on by
+ default if --with-insults is given.
- --with-mail-if-noperms
- Send mail to the "alermail" user if the user is allowed to use sudo but
- the command they are trying is not listed in their sudoers file entry.
+ --with-editor=PATH
+ Specify the default editor path for use by visudo. This may be a
+ single path name or a colon-separated list of editors. In the latter
+ case, visudo will choose the editor that matches the user's VISUAL
+ or EDITOR environment variables or the first editor in the list that
+ exists. The default is the path to vi on your system.
+ Sudoers option: editor
- --with-passprompt="PASSWORD PROMPT"
- Default prompt to use when asking for a password; can be overridden
- via the -p option and the SUDO_PROMPT environment variable. Supports
- the "%H", "%h", "%U" and "%u" escapes as documented in the sudo
- manual page. The default value is "Password:".
+ --with-env-editor
+ Makes visudo consult the VISUAL and EDITOR environment variables before
+ falling back on the default editor list (as specified by --with-editor).
+ Note that this may create a security hole as it allows the user to
+ run any arbitrary command as root without logging. A safer alternative
+ is to use a colon-separated list of editors with the --with-editor
+ option. visudo will then only use the VISUAL or EDITOR variables
+ if they match a value specified via --with-editor.
+ Sudoers option: env_editor
- --with-badpass-message="BAD PASSWORD MESSAGE"
- Message that is displayed if a user enters an incorrect password.
- The default is "Sorry, try again." unless insults are turned on.
+ --with-exempt=GROUP
+ Users in the specified group don't need to enter a password when
+ running sudo. This may be useful for sites that don't want their
+ "core" sysadmins to have to enter a password but where Jr. sysadmins
+ need to. You should probably use NOPASSWD in sudoers instead.
+ Sudoers option: exempt_group
--with-fqdn
- Define this if you want to put fully qualified hostnames in the sudoers
+ Define this if you want to put fully qualified host names in the sudoers
file. Ie: instead of myhost you would use myhost.mydomain.edu. You may
still use the short form if you wish (and even mix the two). Beware
that turning FQDN on requires sudo to make DNS lookups which may make
use the host's official name as DNS knows it. That is, you may not use
a host alias (CNAME entry) due to performance issues and the fact that
there is no way to get all aliases from DNS.
+ Sudoers option: fqdn
- --with-timedir=PATH
- Override the default location of the sudo timestamp directory and
- use "path" instead.
+ --with-goodpri=PRIORITY
+ Determines which syslog priority to log successfully
+ authenticated commands. The following priorities are
+ supported: alert, crit, debug, emerg, err, info, notice,
+ and warning.
+ Sudoers option: syslog_goodpri
- --with-sendmail=PATH
- Override configure's guess as to the location of sendmail.
+ --with-goons-insults
+ Insults the user with lines from the "Goon Show" when an incorrect
+ password is entered. You must either specify --with-insults or
+ enable insults in the sudoers file for this to have any effect.
- --without-sendmail
- Do not use sendmail to mail messages to the "mailto" user.
- Use only if don't run sendmail or the equivalent.
+ --with-hal-insults
+ Uses 2001-like insults when an incorrect password is entered.
+ You must either specify --with-insults or enable insults in the
+ sudoers file for this to have any effect.
- --with-umask=MASK
- Umask to use when running the root command. The default is 0022.
+ --with-ignore-dot
+ If set, sudo will ignore '.' or '' (current dir) in $PATH.
+ The $PATH itself is not modified.
+ Sudoers option: ignore_dot
- --without-umask
- Preserves the umask of the user invoking sudo.
+ --with-insults
+ Define this if you want to be insulted for typing an incorrect password
+ just like the original sudo(8). This is off by default.
+ Sudoers option: insults
- --with-umask-override
- Use the umask specified in sudoers even if it is less restrictive
- than the user's. The default is to use the intersection of the
- user's umask and the umask specified in sudoers.
+ --with-insults=disabled
+ Include support for insults but disable them unless explicitly
+ enabled in sudoers.
+ Sudoers option: !insults
- --with-runas-default=USER
- The default user to run commands as if the -u flag is not specified
- on the command line. This defaults to "root".
+ --with-iologdir[=DIR]
+ By default, sudo stores I/O log files in either /var/log/sudo-io,
+ /var/adm/sudo-io, or /usr/log/sudo-io. If this option is
+ specified, I/O logs will be stored in the indicated directory
+ instead.
+ Sudoers option: iolog_dir
- --with-exempt=GROUP
- Users in the specified group don't need to enter a password when
- running sudo. This may be useful for sites that don't want their
- "core" sysadmins to have to enter a password but where Jr. sysadmins
- need to. You should probably use NOPASSWD in sudoers instead.
+ --with-lecture=no, --without-lecture
+ Don't print the lecture the first time a user runs sudo.
+ Sudoers option: !lecture
- --with-passwd-tries=NUMBER
- Number of tries a user gets to enter his/her password before sudo logs
- the failure and exits. The default is 3.
+ --with-logfac=FACILITY
+ Determines which syslog facility to log to. This requires
+ a 4.3BSD or later version of syslog. You can still set
+ this for ancient syslogs but it will have no effect. The
+ following facilities are supported: authpriv (if your OS
+ supports it), auth, daemon, user, local0, local1, local2,
+ local3, local4, local5, local6, and local7.
+ Sudoers option: syslog
- --with-timeout=NUMBER
- Number of minutes that can elapse before sudo will ask for a passwd
- again. The default is 5, set this to 0 to always prompt for a password.
+ --with-logging=TYPE
+ How you want to do your logging. You may choose "syslog",
+ "file", or "both". Setting this to "syslog" is nice because
+ you can keep all of your sudo logs in one place (see the
+ sample.syslog.conf file). The default is "syslog".
+ Sudoers options: syslog and logfile
- --with-password-timeout=NUMBER
- Number of minutes before the sudo password prompt times out.
- The default is 5, set this to 0 for no password timeout.
+ --with-loglen=NUMBER
+ Number of characters per line for the file log. This is only used if
+ you are to "file" or "both". This value is used to decide when to wrap
+ lines for nicer log files. The default is 80. Setting this to 0
+ will disable the wrapping.
+ Sudoers options: loglinelen
- --without-tty-tickets
- By default, sudo uses a different ticket file for each user/tty combo.
- With this option disabled, a single ticket will be used for all
- of a user's login sessions.
+ --with-logpath=PATH
+ Override the default location of the sudo log file and use
+ "path" instead. By default will use /var/log/sudo.log if
+ there is a /var/log dir, falling back to /var/adm/sudo.log
+ or /usr/adm/sudo.log if not.
+ Sudoers option: logfile
- --with-insults
- Define this if you want to be insulted for typing an incorrect password
- just like the original sudo(8). This is off by default.
+ --with-long-otp-prompt
+ When validating with a One Time Password scheme (S/Key or
+ OPIE), a two-line prompt is used to make it easier to cut
+ and paste the challenge to a local window. It's not as
+ pretty as the default but some people find it more convenient.
+ Sudoers option: long_otp_prompt
- --with-insults=disabled
- Include support for insults but disable them unless explicitly
- enabled in sudoers.
+ --with-mail-if-no-user=no, --without-mail-if-no-user
+ Normally, sudo will mail to the "alertmail" user if the user invoking
+ sudo is not in the sudoers file. This option disables that behavior.
+ Sudoers option: mail_no_user
- --with-all-insults
- Include all the insult sets listed below. You must either specify
- --with-insults or enable insults in the sudoers file for this to
- have any effect.

+ The default user to run commands as if the -u flag is not specified
+ on the command line. This defaults to "root".
+ Sudoers option: runas_default
+
--with-secure-path[=PATH]
Path used for every command run from sudo(8). If you don't trust the
people running sudo to have a sane PATH environment variable you may
for your site. NOTE: this is not applied to users in the group
specified by --with-exemptgroup. If you do not specify a path,
"/bin:/usr/ucb:/usr/bin:/usr/sbin:/sbin:/usr/etc:/etc" is used.
+ Sudoers option: secure_path
- --without-lecture
- Don't print the lecture the first time a user runs sudo.
-
- --with-editor=PATH
- Specify the default editor path for use by visudo. This may be a
- single path name or a colon-separated list of editors. In the latter
- case, visudo will choose the editor that matches the user's VISUAL

- By default, sudo stores I/O log files in either /var/log/sudo-io,
- /var/adm/sudo-io, or /usr/log/sudo-io. If this option is
- specified, I/O logs will be stored in the indicated directory
- instead.
-
- --disable-authentication
- By default, sudo requires the user to authenticate via a
- password or similar means. This options causes sudo to
- *not* require authentication. It is possible to turn
- authentication back on in sudoers via the PASSWD attribute.
-
- --disable-root-sudo
- Don't let root run sudo. This can be used to prevent people from
- "chaining" sudo commands to get a root shell by doing something
- like "sudo sudo /bin/sh".
-
- --enable-gss-krb5-ccache-name
- Use the gss_krb5_ccache_name() function to set the Kerberos
- V credential cache file name. By default, sudo will use
- the KRB5CCNAME environment variable to set this. While
- gss_krb5_ccache_name() provides a better API to do this it
- is not supported by all Kerberos V and SASL combinations.
+ --with-sendmail=PATH
+ Override configure's guess as to the location of sendmail.
+ Sudoers option: mailerpath
- --enable-log-host
- Log the hostname in the log file.

+ Use only if you don't run sendmail or the equivalent.
+ Sudoers options: !mailerpath or !mailto
- --enable-noargs-shell
- If sudo is invoked with no arguments it acts as if the "-s" flag had
- been given. That is, it runs a shell as root (the shell is determined
- by the SHELL environment variable, falling back on the shell listed
- in the invoking user's /etc/passwd entry).
+ --with-sudoers-mode=MODE
+ File mode for the sudoers file (octal). Note that if you
+ wish to NFS-mount the sudoers file this must be group
+ readable. This value may overridden at run-time in the
+ sudo.conf file. The default mode is 0440.
- --enable-shell-sets-home
- If sudo is invoked with the "-s" flag the HOME environment variable
- will be set to the home directory of the target user (which is root
- unless the "-u" option is used). This option effectively makes the
- "-s" flag imply "-H".
+ --with-sudoers-uid=UID
+ User id that "owns" the sudoers file. Note that this is
+ the numeric id, *not* the symbolic name. This value may
+ overridden at run-time in the sudo.conf file. The default
+ is 0.
- --disable-path-info
- Normally, sudo will tell the user when a command could not be found
- in their $PATH. Some sites may wish to disable this as it could
- be used to gather information on the location of executables that
- the normal user does not have access to. The disadvantage is that
- if the executable is simply not in the user's path, sudo will tell
- the user that they are not allowed to run it, which can be confusing.
+ --with-sudoers-gid=GID
+ Group id that "owns" the sudoers file. Note that this is
+ the numeric id, *not* the symbolic name. This value may
+ overridden at run-time in the sudo.conf file. The default
+ is 0.
- --enable-zlib[=location]
- Enable the use of the zlib compress library when storing
- I/O log files. If specified, location is the base directory
- containing the zlib include and lib directories. The special
- values "system" and "builtin" can be used to indicate that
- the system version of zlib should be used or that the version
- of zlib shipped with sudo should be used instead.
- If this option is not specified, configure will use the
- system zlib if it is present.
+ --with-timeout=NUMBER
+ Number of minutes that can elapse before sudo will ask for a passwd
+ again. The default is 5, set this to 0 to always prompt for a password.
+ Sudoers option: timestamp_timeout
- --disable-zlib
- Disable the use of the zlib compress library when storing
- I/O log files.
+ --with-tty-tickets=no, --without-tty-tickets
+ By default, sudo uses a different ticket file for each user/tty combo.
+ With this option disabled, a single ticket will be used for all
+ of a user's login sessions.
+ Sudoers option: tty_tickets
- --enable-warnings
- Enable compiler warnings when building sudo with gcc.
+ --with-umask=MASK
+ Umask to use when running the root command. The default is 0022.
+ Sudoers option: umask
- --enable-werror
- Enable the -Werror compiler option when building sudo with gcc.

+ Preserves the umask of the user invoking sudo.
+ Sudoers option: !umask
- --enable-admin-flag
- Enable the creation of an Ubuntu-style admin flag file
- the first time sudo is run.
+ --with-umask-override
+ Use the umask specified in sudoers even if it is less restrictive
+ than the user's. The default is to use the intersection of the
+ user's umask and the umask specified in sudoers.
+ Sudoers option: umask_override
- --disable-env-reset
- Disable environment resetting. This sets the default value
- of the "env_reset" Defaults option in sudoers to false.
+OS dependent notes
+==================
- --enable-nls[=location]
- Enable natural language support using the gettext() family
- of functions. If specified, location is the base directory
- containing the libintl include and lib directories. If
- this option is not specified, configure will look for the
- gettext() family of functions in the standard C library
- first, then check for a standalone libintl (linking with
- libiconv as needed).
+HP-UX:
+ The default C compiler shipped with HP-UX is not an ANSI compiler.
+ You must use either the HP ANSI C compiler or gcc to build sudo.
+ Binary packages of gcc are available from http://hpux.connect.org.uk/.
- --disable-nls
- Disable natural language support. By default, sudo will
- use the gettext() family of functions, if available, to
- implement messages in the invoking user's native language.
- Note that translations do not exist for all languages.
+ To prevent PAM from overriding the value of umask on HP-UX 11,
+ you will need to add a line like the following to /etc/pam.conf:
-Shadow password and C2 support
-==============================
+ sudo session required libpam_hpsec.so.1 bypass_umask
-Shadow passwords (also included with most C2 security packages) are
-supported on most major platforms for which they exist. The
-`configure' script will attempt to determine if your system can use
-shadow passwords and include support for them if so. Shadow password
-support is now compiled in by default (it doesn't hurt anything if you
-don't have them configured). To disable the shadow password support,
-use the --disable-shadow option to configure.
-
-Shadow passwords are known to work on the following platforms:
-
- SunOS 4.x
- Solaris 2.x
- HP-UX >= 9.x
- Ultrix 4.x
- Digital UNIX
- IRIX >= 5.x
- AIX >= 3.2.x
- Linux
- SCO >= 3.2.2
- Pyramid DC/OSx
- UnixWare
- SVR4 (and variants using standard SVR4 shadow passwords)
- 4.4BSD based systems (including OpenBSD, NetBSD, FreeBSD, and Mac OS X)
- Systems using SecureWare's C2 security.
+ If every command run via sudo displays information about the last
+ successful login and the last authentication failure you should
+ make use an /etc/pam.conf line like:
-OS dependent notes
-==================
+ sudo session required libpam_hpsec.so.1 bypass_umask bypass_last_login
Linux:
PAM and LDAP headers are not installed by default on most Linux
If you wish to build with LDAP support you will also need the
openldap-devel package.
- Versions of glibc 2.x previous to 2.0.7 have a broken lsearch().
- You will need to either upgrade to glibc-2.0.7 or use sudo's
- version of lsearch(). To use sudo's lsearch(), comment out
- the "#define HAVE_LSEARCH 1" line in config.h and add lsearch.o
- to the LIBOBJS line in the Makefile.
-
- If you are using a Linux kernel older than 2.4 it is not possible
- to access the sudoers file via NFS. This is due to a bug in
- the Linux client-side NFS implementation that has since been
- fixed. There is a workaround on the sudo ftp site, linux_nfs.patch,
- if you need to NFS-mount sudoers on older Linux kernels.
-
-Solaris 2.x:
- You need to have a C compiler in order to build sudo. Since
- Solaris 2.x does not come with one by default this means that
- you either need to install the Sun Studio compiler suite,
- available for free from www.sun.com, or have a copy of the GNU
- C compiler (gcc) which is distributed on the Solaris Companion
- CD. You can also get them from various places on the net,
- including http://www.sunfreeware.com/
- NOTE: sudo will *not* build with the sun C compiler in BSD
- compatibility mode (/usr/ucb/cc). Sudo is designed to
- compile with the standard C compiler (or gcc) and will
- not build correctly with /usr/ucb/cc. You can set the
- CC environment variable to the non-ucb compiler when
- running `configure' if it is not the first cc in your
- path. Some sites link /usr/ucb/cc to gcc; configure will
- not notice this and still refuse to use /usr/ucb/cc, so
- make sure gcc is also in your path if your site is setup
- this way.
- Also: Older versions of Solaris come with a broken syslogd.
- If you have having problems with sudo logging you should
- make sure you have the latest syslogd patch installed.
- This is a problem for Solaris 2.4 and 2.5 at least.
-
Mac OS X:
The pseudo-tty support in the Mac OS X kernel has bugs related
to its handling of the SIGTSTP, SIGTTIN and SIGTTOU signals.
logging is enabled. The issue has been reported to Apple and
is bug id #7952709.
-HP-UX:
- The default C compiler shipped with HP-UX is not an ANSI compiler.
- You must use either the HP ANSI C compiler or gcc to build sudo.
- Binary packages of gcc are available from http://hpux.connect.org.uk/.
-
- To prevent PAM from overriding the value of umask on HP-UX 11,
- you will need to add a line like the following to /etc/pam.conf:
-
- sudo session required libpam_hpsec.so.1 bypass_umask
-
-Digital UNIX:
- By default, sudo will use SIA (Security Integration Architecture)
- to validate a user. If you want to use an alternative authentication
- method that does not go through SIA, you need to use the
- --disable-sia option to configure. If you use gcc to compile
- you will get warnings when building interfaces.c. These are
- harmless but if they really bug you, you can edit
- /usr/include/net/if.h around line 123, right after the comment:
- /* forward decls for C++ */
- change the line:
- #ifdef __cplusplus
- to:
- #if defined(__cplusplus) || defined(__GNUC__)
- If you don't like the idea of editing the system header file
- you can just make a copy in gcc's private include tree and
- edit that.
-
-AIX 3.2.x:
- I've had various problems with the AIX C compiler producing
- incorrect code when the -O flag was used. When optimization
- is not used, the problems go away. Gcc does not appear
- to have this problem.
-
-SCO ODT:
- You'll probably need libcrypt_i.a available via anonymous ftp
- from sosco.sco.com. The necessary files are /SLS/lng225b.Z
- and /SLS/lng225b.ltr.Z.
+Solaris:
+ You need to have a C compiler in order to build sudo. Since
+ Solaris does not come with one by default this means that you
+ either need to either install the Solaris Studio compiler suite,
+ available for free from www.oracle.com, or install the GNU C

+ on Solaris 11 and higher and is distributed on the Solaris
+ Companion CD for older Solaris releases. You can also download
+ gcc packages from http://www.opencsw.org/packages/CSWgcc4core/
SunOS 4.x:
SunOS does not ship with an ANSI C compiler. You will need to
The /bin/sh shipped with SunOS blows up while running configure.
You can work around this by installing bash or zsh. If you
- have bash or zsh in your path, configure will use it instead
- automatically.
-
-ULTRIX 4.x:
- ULTRIX does not ship with an ANSI C compiler. You will need to
- install an ANSI compiler such as gcc to build sudo.
-
- The /bin/sh shipped with ULTRIX blows up while running configure.
- You can work around this by installing bash or zsh. If you
- have bash or zsh in your path, configure will use it instead
- automatically.
-
- ULTRIX ships with the 4.2BSD syslog(3) which does not
- allow things like logging different facilities to different
- files, redirecting logs to a single loghost and other niceties.
- You may want to just grab and install:
- ftp://www.sudo.ws/pub/sudo/misc/jtkohl-syslog-complete.tar.gz
- (available via anonymous ftp) which is a port if the 4.3BSD
- syslog/syslogd that is backwards compatible with the Ultrix version.
- I recommend it highly. If you do not do this you probably want
- to run configure with --with-logging=file
+ have bash or zsh in your path, configure will use it automatically.
