Re: ssh in SLES10 SP1 RC2

Tony: Here's the guts of the first message in the original thread and the replies I got ........ Essentially what I'm not seeing in the audit.log file is the USER_END statement after a ssh session is terminated. For my purposes the end of any session (ssh, console, gui) needs to be recorded. ============================================= Steve: Thanks for the quick response - Did a little test on a X86-64 SLES10 SP1 RC2 system - sshed into in and did see the USER_LOGIN line then got out via either an exit or logout and never see an USER_END statement. Here's the relevant lines from /var/log/audit/audit.log: type=USER_AUTH msg=audit(1180108586.633:1292): user pid=31247 uid=0 auid=4294967295 msg='PAM: authentication acct=mwfolsom : exe="/usr/sbin/sshd" (hostname=X.X.X, addr=X.X.X.X, terminal=ssh res=success)' type=USER_ACCT msg=audit(1180108586.633:1293): user pid=31247 uid=0 auid=4294967295 msg='PAM: accounting acct=mwfolsom : exe="/usr/sbin/sshd" (hostname=X.X.X, addr=X.X.X.X,, terminal=ssh res=success)' type=LOGIN msg=audit(1180108586.637:1294): login pid=31248 uid=0 old auid=4294967295 new auid=6122 type=USER_START msg=audit(1180108586.637:1295): user pid=31248 uid=0 auid=6122 msg='PAM: session open acct=mwfolsom : exe="/usr/sbin/sshd" (hostname=X.X.X, addr=X.X.X.X, terminal=ssh res=success)' type=CRED_REFR msg=audit(1180108586.637:1296): user pid=31248 uid=0 auid=6122 msg='PAM: setcred acct=mwfolsom : exe="/usr/sbin/sshd" (hostname=X.X.X, addr=X.X.X.X, terminal=ssh res=success)' type=USER_LOGIN msg=audit(1180108586.641:1297): user pid=31245 uid=0 auid=4294967295 msg='uid=6122: exe="/usr/sbin/sshd" (hostname=X.X.X, addr=X.X.X.X, terminal=/dev/pts/1 res=success) gui, the console, and ssh and then using grep on the log file it appears that the other two routes record both login's and logout's but ssh only records logins. ------ On Friday 25 May 2007 13:21, Michael Folsom wrote: If I remember correctly, there was a bug in a patch to sshd that called pam_session_close from the unprivileged process. I think we moved this and sent the patch upstream. There might be a sshd patch that needs backporting from openssh cvs. -Steve ------- Yep, based on some earlier emails I saved, I think Steve said that ssh needs to be at version 4.3p2-13 or later to generate logout (USER_END) audit records correctly. Karen Wieprecht ======================================== The x86-64 test system is running SLES10 SP1 rc2 I set the system up for auditing based on a "SLE10 Auditing Quickstart" guide I got from someone at Novell. This is how I set the system up: ------------------------------------------------------ Configure Audit 1. Be sure you are logged in as root 2. rcauditd stop 3. rm /var/log/audit/audit.log NOTE: I like to clear the audit.log show and start with a fresh log file for testing. 4. Edit /etc/sysconfig/auditd 1. Change AUDITD_DISABLE_CONTEXTS to no NOTE: This enables syscall auditing 5. Edit /etc/auditd.conf 1. Change flush from INCREMENTAL to SYNC NOTE: This is for testing purposes only, INCREMENTAL would be a better option in production auditing 6. Edit /etc/audit/rules 1. Add the following line to the bottom of the file: -w /etc/audit.rules -k fk_auditrules NOTE: This rule will audit the /etc/audit.rules file. 7. Edit /etc/pam.d/{login,gdm,xdm,sshd,crond,atd} NOTE: Adds UID info to audit entries for watched files 1. Add the following line: session required pam_loginuid.so before the line "session include common-session" 8. rcauditd start Advice will be appreciated - Thanks!
