1 Installation instructions for Sudo 1.7
2 ======================================
4 Sudo uses a `configure' script to probe the capabilities and type
5 of the system in question. In this release, `configure' takes many
6 more options than it did before. Please read this document fully
7 before configuring and building sudo. You may also wish to read the
8 file INSTALL.configure which explains more about the `configure' script.
10 Simple sudo installation
11 ========================
13 For most systems and configurations it is possible simply to:
15 0) If you are upgrading from a previous version of sudo
16 please read the info in the UPGRADE file before proceeding.
18 1) Read the `OS dependent notes' section for any particular
19 "gotchas" relating to your operating system.
21 2) `cd' to the source or build directory and type `./configure'
22 to generate a Makefile and config.h file suitable for
23 building sudo. Before you actually run configure you
24 should read the `Available configure options' section
25 to see if there are any special options you may want
28 3) Edit the configure-generated Makefile if you wish to
29 change any of the default paths (alternatively, you could
30 have changed the paths via options to `configure'.
32 5) Type `make' to compile sudo. If you are building sudo
33 in a separate build tree (apart from the sudo source)
34 GNU make will probably be required. If `configure' did
35 its job properly (and you have a supported configuration)
36 there won't be any problems. If this doesn't work, take
37 a look at the files TROUBLESHOOTING and PORTING for tips
38 on what might have gone wrong. Please mail us if you have a
39 fix or if you are unable to come up with a fix (address at EOF).
41 6) Type `make install' (as root) to install sudo, visudo, the
42 man pages, and a skeleton sudoers file. Note that the install
43 will not overwrite an existing sudoers file. You can also
44 install various pieces the package via the install-binaries,
45 install-doc, and install-sudoers make targets.
47 7) Edit the sudoers file with `visudo' as necessary for your
48 site. You will probably want to refer the sample.sudoers
49 file and sudoers man page included with the sudo package.
51 8) If you want to use syslogd(8) to do the logging, you'll need
52 to update your /etc/syslog.conf file. See the sample.syslog.conf
53 file included in the distribution for an example.
55 Available configure options
56 ===========================
58 This section describes flags accepted by the sudo's `configure' script.
59 Defaults are listed in brackets after the description.
63 Cache test results in FILE
66 Alias for `--cache-file=config.cache'
69 Print the usage/help info
72 Do not create output files
75 Do not print `checking...' messages
77 Directory and file names:
79 Install architecture-independent files in PREFIX This really only
80 applies to man pages. [/usr/local]
83 Install architecture-dependent files in EPREFIX This includes the
84 sudo and visudo executables. [same as prefix]
87 Install `sudo' in DIR [EPREFIX/bin]
90 Install `visudo' in DIR [EPREFIX/sbin]
93 Install `sudoers' file in DIR [/etc]
96 Install man pages in DIR [PREFIX/man]
99 Find the sources in DIR [configure dir or ..]
101 Special features/options:
103 Specifies path to C compiler you wish to use.
106 Adds the specified directory (or directories) to CPPFLAGS
107 so configure and the compiler will look there for include
108 files. Multiple directories may be specified as long as
109 they are space separated.
110 Eg: --with-incpath="/usr/local/include /opt/include"
113 Adds the specified directory (or directories) to LDFLAGS
114 so configure and the compiler will look there for libraries.
115 Multiple directories may be specified as with --with-incpath.
118 Tells configure to use -Rpath in addition to -Lpath when
119 passing library paths to the loader. This option is on
120 by default for Solaris and SVR4.
122 --with-blibpath[=PATH]
123 Tells configure to construct a -blibpath argument to the
124 loader. If a PATH is specified, it will be used as the
125 base. Otherwise, "/usr/lib:/lib:/usr/local/lib" will be
126 used for gcc and "/usr/lib:/lib" for non-gcc. Additional
127 library paths will be appended as needed by configure.
128 This option is only valid for AIX where it is on by default.
130 --with-libraries=LIBRARY
131 Adds the specified library (or libaries) to SUDO_LIBS and
132 and VISUDO_LIBS so sudo will link against them. If the
133 library doesn't start with `-l' or end in `.a' or `.o' a
134 `-l' will be prepended to it. Multiple libraries may be
135 specified as long as they are space separated.
138 Link with the "electric fence" debugging malloc.
141 Enable support for sudo BSM audit logs on systems that support
142 it. Currently only supported under FreeBSD and Mac OS X.
145 Enable audit support for Linux systems. Audits attempts
146 to run a command as well as SELinux role changes.
149 Add CSOps standard options. You probably aren't interested in this.
152 Enable S/Key OTP (One Time Password) support. If specified,
153 DIR should contain include and lib directories with skey.h
154 and libskey.a respectively.
157 Enable NRL OPIE OTP (One Time Password) support. If specified,
158 DIR should contain include and lib directories with opie.h
159 and libopie.a respectively.
162 Enable SecurID support. If specified, DIR is directory containing
163 sdiclient.a, sdi_athd.h, sdconf.h, and sdacmvls.h.
166 Enable TIS Firewall Toolkit (FWTK) 'authsrv' support. If specified,
167 DIR is the base directory containing the compiled FWTK package
168 (or at least the library and header files).
171 Enable Kerberos IV support. If specified, DIR is the base
172 directory containing the Kerberos IV include and lib dirs.
173 This uses Kerberos passphrases for authentication but does
174 not use the Kerberos cookie scheme.
177 Enable Kerberos V support. If specified, DIR is the base
178 directory containing the Kerberos V include and lib dirs.
179 This This uses Kerberos passphrases for authentication but
180 does not use the Kerberos cookie scheme. Will not work for
181 Kerberos V older than version 1.1.
184 Enable LDAP support. If specified, DIR is the base directory
185 containing the LDAP include and lib directories. Please see
186 README.LDAP for more information.
188 --with-ldap-conf-file=PATH
189 Path to LDAP configuration file. If specified, sudo reads
190 this file instead of /etc/ldap.conf to locate the LDAP server.
192 --with-ldap-secret-file=PATH
193 Path to LDAP secret password file. If specified, sudo uses
194 this file instead of /etc/ldap.secret to read the secret password
195 when rootbinddn is specified in the ldap config file.
197 --with-nsswitch[=PATH]
198 Path to nsswitch.conf or "no" to disable nsswitch support.
199 If specified, sudo uses this file instead of /etc/nsswitch.conf.
200 If nsswitch is disabled but LDAP is enabled, sudo will check
201 LDAP first, then the sudoers file.
204 Path to netsvc.conf or "no" to disable netsvc.conf support.
205 If specified, sudo uses this file instead of /etc/netsvc.conf
209 Enable support for the AIX 4.x general authentication function.
210 This will use the authentication scheme specified for the user
211 on the machine. It is on by default for AIX systems that
215 Enable PAM support. This is on by default for Darwin, FreeBSD,
216 Linux, Solaris and HP-UX (version 11 and higher).
218 NOTE: on RedHat Linux and Fedora you *must* have an /etc/pam.d/sudo
219 file install. You may either use the sample.pam file included with
220 sudo or use /etc/pam.d/su as a reference. The sample.pam file
221 included with sudo may or may not work with other Linux distributions.
222 On Solaris and HP-UX 11 systems you should check (and understand)
223 the contents of /etc/pam.conf. Do a "man pam.conf" for more
224 information and consider using the "debug" option, if available,
225 with your PAM libraries in /etc/pam.conf to obtain syslog output
226 for debugging purposes.
229 Enable a specific PAM session when sudo is given the -i option.
230 This changes the PAM service name when sudo is run with the -i
231 option from "sudo" to "sudo-i", allowing for a separate pam
232 configuration for sudo's initial login mode.
235 Enable AFS support with Kerberos authentication. Should work under
236 AFS 3.3. If your AFS doesn't have -laudit you should be able to
240 Enable DCE support for systems without PAM. Known to work on
241 HP-UX 9.X, 10.X, and 11.0; other systems may require source
242 code and/or `configure' changes. On systems with PAM support
243 (such as HP-UX 11.0 and higher, Solaris, FreeBSD and Linux), the
244 DCE PAM module (usually libpam_dce) should be used instead.
247 This adds support for login classes specified in /etc/login.conf.
248 It is enabled by default on BSD/OS, Darwin, FreeBSD, OpenBSD and
249 NetBSD (where available). By default, a login class is not applied
250 unless the 'use_loginclass' option is defined in sudoers or the user
251 specifies a class on the command line.
254 Enable support for BSD authentication. This is the default
255 for BSD/OS and OpenBSD systems that support it.
256 It is not possible to mix BSD authentication with other
257 authentication methods (and there really should be no need
258 to do so). Note that only the newer BSD authentication API
259 is supported. If you don't have /usr/include/bsd_auth.h
260 then you cannot use this.
263 Enable support for Solaris project resource limits.
264 This option is only available on Solaris 9 and above.
267 Enable support for the "noexec" functionality which prevents
268 a dynamically-linked program being run by sudo from executing
269 another program (think shell escapes). Please see the
270 "PREVENTING SHELL ESCAPES" section in the sudoers man page
271 for details. If specified, PATH should be a fully qualified
272 path name, e.g. /usr/local/libexec/sudo_noexec.so. If PATH
273 is "no", noexec support will not be compiled in. The default
274 is to compile noexec support if libtool supports building
275 shared objects on your OS.
277 --disable-pam-session
278 Disable sudo's PAM session support. This may be needed on
279 older PAM implementations or on operating systems where
280 opening a PAM session changes the utmp or wtmp files. If
281 PAM session support is disabled, resource limits may not
282 be updatedin for command being run.
284 --disable-root-mailer
285 By default sudo will run the mailer as root when tattling
286 on a user so as to prevent that user from killing the mailer.
287 With this option, sudo will run the mailer as the invoking
288 user which some people consider to be safer.
291 Disable use of the setreuid() function for operating systems
292 where it is broken. Mac OS X has setreuid() but it doesn't
296 Disable use of the setresuid() function for operating systems
297 where it is broken (none currently known).
300 Disable SIA support. This is the "Security Integration
301 Architecture" on Digital UNIX. If you disable SIA sudo will
302 use its own authentication routines.
305 Disable shadow password support. Normally, sudo will compile
306 in shadow password support and use a shadow password if it
309 --with-sudoers-mode=MODE
310 File mode for the sudoers file (octal). Note that if you
311 wish to NFS-mount the sudoers file this must be group
312 readable. Also note that this is actually set in the
313 Makefile. The default mode is 0440.
315 --with-sudoers-uid=UID
316 User id that "owns" the sudoers file. Note that this is
317 the numeric id, *not* the symbolic name. Also note that
318 this is actually set in the Makefile. The default is 0.
320 --with-sudoers-gid=GID
321 Group id that "owns" the sudoers file. Note that this is
322 the numeric id, *not* the symbolic name. Also note that
323 this is actually set in the Makefile. The default is 0.
326 This option keeps sudo from trying to glean the ip address
327 from each attached ethernet interface. It is only useful
328 on a machine where sudo's interface reading support does
329 not work, which may be the case on some SysV-based OS's
333 This option excludes authentication via the passwd (or
334 shadow) file. It should only be used when another, alternative,
335 authentication scheme is in use.
338 This option is now just an alias for --without-passwd.
341 Properly handle GNU stow packaging. The sudoers file will
342 physically live in ${prefix}/etc and /etc/sudoers will be
346 Enable support for role based access control (RBAC) on
347 systems that support SELinux.
350 Enable non-Unix group support using Quest Authentication
351 Services. If NAME is specified, it should be the name of
352 the shared library providing QAS support (libvas.so by default).
354 --with-libvas-rpath=[PATH]
355 The path to search when loading libvas.so (or an alternate
356 name as specified by --with-libvas). This option only has
357 an effect when --with-libvas is specified.
359 The following options are also configurable at runtime:
361 --with-long-otp-prompt
362 When validating with a One Time Password scheme (S/Key or
363 OPIE), a two-line prompt is used to make it easier to cut
364 and paste the challenge to a local window. It's not as
365 pretty as the default but some people find it more convenient.
368 How you want to do your logging. You may choose "syslog",
369 "file", or "both". Setting this to "syslog" is nice because
370 you can keep all of your sudo logs in one place (see the
371 sample.syslog.conf file). The default is "syslog".
373 --with-logfac=FACILITY
374 Determines which syslog facility to log to. This requires
375 a 4.3BSD or later version of syslog. You can still set
376 this for ancient syslogs but it will have no effect. The
377 following facilities are supported: authpriv (if your OS
378 supports it), auth, daemon, user, local0, local1, local2,
379 local3, local4, local5, local6, and local7.
381 --with-goodpri=PRIORITY
382 Determines which syslog priority to log successfully
383 authenticated commands. The following priorities are
384 supported: alert, crit, debug, emerg, err, info, notice,
387 --with-badpri=PRIORITY
388 Determines which syslog priority to log unauthenticated
389 commands and errors. The following priorities are supported:
390 alert, crit, debug, emerg, err, info, notice, and warning.
393 Override the default location of the sudo log file and use
394 "path" instead. By default will use /var/log/sudo.log if
395 there is a /var/log dir, falling back to /var/adm/sudo.log
396 or /usr/adm/sudo.log if not.
399 Number of characters per line for the file log. This is only used if
400 you are to "file" or "both". This value is used to decide when to wrap
401 lines for nicer log files. The default is 80. Setting this to 0
402 will disable the wrapping.
405 If set, sudo will ignore '.' or '' (current dir) in $PATH.
406 The $PATH itself is not modified.
408 --with-mailto=USER|MAIL_ALIAS
409 User (or mail alias) that mail from sudo is sent to.
410 This should go to a sysadmin at your site. The default is "root".
412 --with-mailsubject="SUBJECT OF MAIL"
413 Subject of the mail sent to the "mailto" user. The token "%h"
414 will expand to the hostname of the machine.
415 Default is "*** SECURITY information for %h ***".
417 --without-mail-if-no-user
418 Normally, sudo will mail to the "alertmail" user if the user invoking
419 sudo is not in the sudoers file. This option disables that behavior.
421 --with-mail-if-no-host
422 Send mail to the "alermail" user if the user exists in the sudoers
423 file, but is not allowed to run commands on the current host.
425 --with-mail-if-noperms
426 Send mail to the "alermail" user if the user is allowed to use sudo but
427 the command they are trying is not listed in their sudoers file entry.
429 --with-passprompt="PASSWORD PROMPT"
430 Default prompt to use when asking for a password; can be overridden
431 via the -p option and the SUDO_PROMPT environment variable. Supports
432 the "%H", "%h", "%U" and "%u" escapes as documented in the sudo
433 manual page. The default value is "Password:".
435 --with-badpass-message="BAD PASSWORD MESSAGE"
436 Message that is displayed if a user enters an incorrect password.
437 The default is "Sorry, try again." unless insults are turned on.
440 Define this if you want to put fully qualified hostnames in the sudoers
441 file. Ie: instead of myhost you would use myhost.mydomain.edu. You may
442 still use the short form if you wish (and even mix the two). Beware
443 that turning FQDN on requires sudo to make DNS lookups which may make
444 sudo unusable if your DNS is totally hosed. Also note that you must
445 use the host's official name as DNS knows it. That is, you may not use
446 a host alias (CNAME entry) due to performance issues and the fact that
447 there is no way to get all aliases from DNS.
450 Override the default location of the sudo timestamp directory and
454 Override configure's guess as to the location of sendmail.
457 Do not use sendmail to mail messages to the "mailto" user.
458 Use only if don't run sendmail or the equivalent.
461 Umask to use when running the root command. The default is 0022.
464 Preserves the umask of the user invoking sudo.
466 --with-umask-override
467 Use the umask specified in sudoers even if it is less restrictive
468 than the user's. The default is to use the intersection of the
469 user's umask and the umask specified in sudoers.
471 --with-runas-default=USER
472 The default user to run commands as if the -u flag is not specified
473 on the command line. This defaults to "root".
476 Users in the specified group don't need to enter a password when
477 running sudo. This may be useful for sites that don't want their
478 "core" sysadmins to have to enter a password but where Jr. sysadmins
479 need to. You should probably use NOPASSWD in sudoers instead.
481 --with-passwd-tries=NUMBER
482 Number of tries a user gets to enter his/her password before sudo logs
483 the failure and exits. The default is 3.
485 --with-timeout=NUMBER
486 Number of minutes that can elapse before sudo will ask for a passwd
487 again. The default is 5, set this to 0 to always prompt for a password.
489 --with-password-timeout=NUMBER
490 Number of minutes before the sudo password prompt times out.
491 The default is 5, set this to 0 for no password timeout.
493 --without-tty-tickets
494 By default, sudo uses a different ticket file for each user/tty combo.
495 With this option disabled, a single ticket will be used for all
496 of a user's login sessions.
499 Define this if you want to be insulted for typing an incorrect password
500 just like the original sudo(8). This is off by default.
502 --with-insults=disabled
503 Include support for insults but disable them unless explicitly
507 Include all the insult sets listed below. You must either specify
508 --with-insults or enable insults in the sudoers file for this to
511 --with-classic-insults
512 Uses insults from sudo "classic." If you just specify --with-insults
513 you will get the classic and CSOps insults. This is on by default if
514 --with-insults is given.
517 Insults the user with an extra set of insults (some quotes, some
518 original) from a sysadmin group at CU (CSOps). You must specify
519 --with-insults as well for this to have any effect. This is on by
520 default if --with-insults is given.
523 Uses 2001-like insults when an incorrect password is entered.
524 You must either specify --with-insults or enable insults in the
525 sudoers file for this to have any effect.
528 Insults the user with lines from the "Goon Show" when an incorrect
529 password is entered. You must either specify --with-insults or
530 enable insults in the sudoers file for this to have any effect.
533 Replace politically incorrect insults with less objectionable ones.
535 --with-secure-path[=PATH]
536 Path used for every command run from sudo(8). If you don't trust the
537 people running sudo to have a sane PATH environment variable you may
538 want to use this. Another use is if you want to have the "root path"
539 be separate from the "user path." You will need to customize the path
540 for your site. NOTE: this is not applied to users in the group
541 specified by --with-exemptgroup. If you do not specify a path,
542 "/bin:/usr/ucb:/usr/bin:/usr/sbin:/sbin:/usr/etc:/etc" is used.
545 Don't print the lecture the first time a user runs sudo.
548 Specify the default editor path for use by visudo. This may be a
549 single path name or a colon-separated list of editors. In the latter
550 case, visudo will choose the editor that matches the user's VISUAL
551 or EDITOR environment variables or the first editor in the list that
552 exists. The default is the path to vi on your system.
555 Makes visudo consult the VISUAL and EDITOR environment variables before
556 falling back on the default editor list (as specified by --with-editor).
557 Note that this may create a security hole as it allows the user to
558 run any arbitrary command as root without logging. A safer alternative
559 is to use a colon-separated list of editors with the --with-editor
560 option. visudo will then only use the VISUAL or EDITOR variables
561 if they match a value specified via --with-editor.
564 Set PATH as the "askpass" program to use when no tty is
565 available. Typically, this is a graphical password prompter,
566 similar to the one used by ssh. The program must take a
567 prompt as an argument and print the received password to
571 Disable sudo's I/O logging support. This can be used to allow sudo
572 to be compiled on systems without pseudo-tty support.
574 --with-iologdir[=DIR]
575 By default, sudo stores I/O log files in either /var/log/sudo-io,
576 /var/adm/sudo-sudo-io or /usr/log/sudo-io. If DIR is
577 specified, I/O logs will be stored in the indicated directory
580 --disable-authentication
581 By default, sudo requires the user to authenticate via a
582 password or similar means. This options causes sudo to
583 *not* require authentication. It is possible to turn
584 authentication back on in sudoers via the PASSWD attribute.
587 Don't let root run sudo. This can be used to prevent people from
588 "chaining" sudo commands to get a root shell by doing something
589 like "sudo sudo /bin/sh".
591 --enable-gss-krb5-ccache-name
592 Use the gss_krb5_ccache_name() function to set the Kerberos
593 V credential cache file name. By default, sudo will use
594 the KRB5CCNAME environment variable to set this. While
595 gss_krb5_ccache_name() provides a better API to do this it
596 is not supported by all Kerberos V and SASL combinations.
599 Log the hostname in the log file.
601 --enable-noargs-shell
602 If sudo is invoked with no arguments it acts as if the "-s" flag had
603 been given. That is, it runs a shell as root (the shell is determined
604 by the SHELL environment variable, falling back on the shell listed
605 in the invoking user's /etc/passwd entry).
607 --enable-shell-sets-home
608 If sudo is invoked with the "-s" flag the HOME environment variable
609 will be set to the home directory of the target user (which is root
610 unless the "-u" option is used). This option effectively makes the
611 "-s" flag imply "-H".
614 Normally, sudo will tell the user when a command could not be found
615 in their $PATH. Some sites may wish to disable this as it could
616 be used to gather information on the location of executables that
617 the normal user does not have access to. The disadvantage is that
618 if the executable is simply not in the user's path, sudo will tell
619 the user that they are not allowed to run it, which can be confusing.
621 --enable-zlib[=location]
622 Enable the use of the zlib compress library when storing
623 I/O log files. If specified, location is the base directory
624 containing the zlib include and lib directories. The special
625 values "system" and "builtin" can be used to indicate that
626 the system version of zlib should be used or that the version
627 of zlib shipped with sudo should be used instead.
628 If this option is not specified, configure will use the
629 system zlib if it is present and I/O logging support has
633 Disable the use of the zlib compress library when storing
637 Enable compiler warnings when building sudo with gcc.
640 Enable the creation of an Ubuntu-style admin flag file
641 the first time sudo is run.
644 Disable environment resetting. This sets the default value
645 of the "env_reset" Defaults option in sudoers to false.
647 Shadow password and C2 support
648 ==============================
650 Shadow passwords (also included with most C2 security packages) are
651 supported on most major platforms for which they exist. The
652 `configure' script will attempt to determine if your system can use
653 shadow passwords and include support for them if so. Shadow password
654 support is now compiled in by default (it doesn't hurt anything if you
655 don't have them configured). To disable the shadow password support,
656 use the --disable-shadow option to configure.
658 Shadow passwords are known to work on the following platforms:
671 SVR4 (and variants using standard SVR4 shadow passwords)
672 4.4BSD based systems (including OpenBSD, NetBSD, FreeBSD, and Mac OS X)
673 Systems using SecureWare's C2 security.
679 PAM and LDAP headers are not installed by default on most Linux
680 systems. You will need to install the "pam-dev" package if
681 /usr/include/security/pam_appl.h is not present on your system.
682 If you wish to build with LDAP support you will also need the
683 openldap-devel package.
685 Versions of glibc 2.x previous to 2.0.7 have a broken lsearch().
686 You will need to either upgrade to glibc-2.0.7 or use sudo's
687 version of lsearch(). To use sudo's lsearch(), comment out
688 the "#define HAVE_LSEARCH 1" line in config.h and add lsearch.o
689 to the LIBOBJS line in the Makefile.
691 If you are using a Linux kernel older than 2.4 it is not possible
692 to access the sudoers file via NFS. This is due to a bug in
693 the Linux client-side NFS implementation that has since been
694 fixed. There is a workaround on the sudo ftp site, linux_nfs.patch,
695 if you need to NFS-mount sudoers on older Linux kernels.
698 You need to have a C compiler in order to build sudo. Since
699 Solaris 2.x does not come with one by default this means that
700 you either need to install the Sun Studio compiler suite,
701 available for free from www.sun.com, or have a copy of the GNU
702 C compiler (gcc) which is distributed on the Solaris Companion
703 CD. You can also get them from various places on the net,
704 including http://www.sunfreeware.com/
705 NOTE: sudo will *not* build with the sun C compiler in BSD
706 compatibility mode (/usr/ucb/cc). Sudo is designed to
707 compile with the standard C compiler (or gcc) and will
708 not build correctly with /usr/ucb/cc. You can use the
709 `--with-CC' option to point `configure' to the non-ucb
710 compiler if it is not the first cc in your path. Some
711 sites link /usr/ucb/cc to gcc; configure will not notice
712 this and still refuse to use /usr/ucb/cc, so make sure gcc
713 is also in your path if your site is setup this way.
714 Also: Older versions of Solaris come with a broken syslogd.
715 If you have having problems with sudo logging you should
716 make sure you have the latest syslogd patch installed.
717 This is a problem for Solaris 2.4 and 2.5 at least.
720 The pseudo-tty support in the Mac OS X kernel has bugs related
721 to its handling of the SIGTSTP, SIGTTIN and SIGTTOU signals.
722 It does not restart reads and writes when those signals are
723 delivered. This may cause problems for some commands when I/O
724 logging is enabled. The issue has been reported to Apple and
728 The default C compiler shipped with HP-UX does not support
729 creating position independent code and so is unable to support
730 sudo's "noexec" functionality. You must use either the HP ANSI
731 C compiler or gcc for noexec to work. Binary packages of gcc
732 are available http://hpux.connect.org.uk/.
734 To prevent PAM from overriding the value of umask on HP-UX 11,
735 you will need to add a line like the following to /etc/pam.conf:
737 sudo session required libpam_hpsec.so.1 bypass_umask
740 By default, sudo will use SIA (Security Integration Architecture)
741 to validate a user. If you want to use an alternative authentication
742 method that does not go through SIA, you need to use the
743 --disable-sia option to configure. If you use gcc to compile
744 you will get warnings when building interfaces.c. These are
745 harmless but if they really bug you, you can edit
746 /usr/include/net/if.h around line 123, right after the comment:
747 /* forward decls for C++ */
751 #if defined(__cplusplus) || defined(__GNUC__)
752 If you don't like the idea of editing the system header file
753 you can just make a copy in gcc's private include tree and
757 I've had various problems with the AIX C compiler producing
758 incorrect code when the -O flag was used. When optimization
759 is not used, the problems go away. Gcc does not appear
760 to have this problem.
763 You'll probably need libcrypt_i.a available via anonymous ftp
764 from sosco.sco.com. The necessary files are /SLS/lng225b.Z
765 and /SLS/lng225b.ltr.Z.
768 The /bin/sh shipped with SunOS blows up while running configure.
769 You can work around this by installing bash or zsh. If you
770 have bash or zsh in your path, configure will use it instead
774 The /bin/sh shipped with ULTRIX blows up while running configure.
775 You can work around this by installing bash or zsh. If you
776 have bash or zsh in your path, configure will use it instead
779 ULTRIX ships with the 4.2BSD syslog(3) which does not
780 allow things like logging different facilities to different
781 files, redirecting logs to a single loghost and other niceties.
782 You may want to just grab and install:
783 ftp://www.sudo.ws/pub/sudo/misc/jtkohl-syslog-complete.tar.gz
784 (available via anonymous ftp) which is a port if the 4.3BSD
785 syslog/syslogd that is backwards compatible with the Ultrix version.
786 I recommend it highly. If you do not do this you probably want
787 to run configure with --with-logging=file
