invalid login attempts...
I am wondering if solaris captures id's associated w/invalid login attempts?

when I try to login as "test1" several (3-5) times, I do not find any userID info under "/var/adm" files:
utmpx
wtmpx
messages
lastlog

Is there another location/log I should be checking?
Is it necessary for "test1" to exist in /etc/passwd before this information is captured?

thanks,
manny

Set the auth.info facility.level in /etc/syslog.conf and point it to a log (/var/log/authlog for example). Ensure the log file exists. Restart syslog and attempt the log in.

Code:

I have updated my syslog.conf with the following auth.x entries (and cycled syslogd) :
auth.notice;auth.crit;auth.info /var/log/authlog

I see that login failure information is being captured, but the ID (or even a Generic ID) is NOT...

Nov 29 08:19:30 testBOX.com login: [ID 760094 auth.crit] REPEATED LOGIN FAILURES ON /dev/pts/2 FROM mybox.com


Also, does anyone know where I can get a list of valid facilities?
wondering what other options are out there...
thanks

man syslogd.conf will show the list of valid facilities and levels.

Don't know why login doesn't report the name. It's clear that sshd does though.

It looks like the ID is captured from invalid ssh attempts, but NOT regular telnet attempts:

messages from telnet attempts as "test1" in authlog:

Carl, thanks again for the info...

Invalid ssh connections are captured in /var/log/authlog (see above - from /etc/syslog.conf).
and
Invalid telnet connections are captured in /var/adm/loginlog?
# cat loginlog
test1:/dev/pts/2:Thu Dec 1 09:02:27 2005
test1:/dev/pts/2:Thu Dec 1 09:02:32 2005
test1:/dev/pts/2:Thu Dec 1 09:02:40 2005

Does anyone ever update there syslog.conf to consolidate this info into a single file?
