sendmail - who am I really ?

[Michael Tully]

ha... some fun... This is starting to drive me crazy...

I've already run the *ck progs, and we don't have a trusted system. It is not good opening another session, as the problem does not get reproduced.
no env changes, no strange su's....

no wtmp/utmp corruption

the tusc output.... Well that didn't really show anything...

knock yourself out.....

Its actually beer time, I'm outta here, I check a bit later.

Cheers

Michael,

I've got the same problem on sun/solaris after implementing logical connection security, root can only login to system on local console, su works fine but mail will be sent with original login id.

Called Sun's crc, but they could not give me an answer ?

If you get any answers from your lady's cards PLEASE let me know.

I'll start looking in to a crystal bowl for the mean time.

Kind regards,

Robert-Jan.

Robert-Jan,

I think you've mis-understood the question....

The output from tusc, doesn't look like it made it, so I'll re-post it tomorrow AM my time. I'm certainly all for more suggestions....

Hi

I had the same effect on some machines and I answered to thread
http://forums.itrc.hp.com/cm/QuestionAnswer/1,,0x2d9f93e260b0d611abdb0090277a778c,00.html

In our case it's a problem with utmp/wtmp files and login via ssh:

whoami --> root
who am i --> root
id --> uid=0(root) gid=...
logname -->

Solution:

empty /etc/utmp /etc/utmpx /var/adm/wtmpx /var/adm/wtmp
and reboot the machine

Here is the tusc output for anyone that is interested.

Unfortunately we do not use 'ssh' for some of our systems, this is one. None of the Xtmp file are corrupted.

That lady with the deck of cards is lokking better all the time.....

What type of crystal ball do you need to read that attachment Michael? ;-)

[Christian Gebhardt]

Hi
Nethertheless
what's the output from 'logname'?

logname uses the same routine to show the user as sendmail.

My grandma is very familiar with cards ...

Hi
netherless, what's the output from 'logname' ?
logname uses the same routines as sendmail to fetch the user.

Maybe you have a corrupt utmp/wtmp file.Create new one.

do a backup of the files, then
cp /dev/null /etc/utmp
...

logoutand then login again,if you use "logname" ,it will now give the correct user

Attention: Your current logon-information will be lost (so it would be the best that all users logout from the system)

[Michael Tully]

Unfortunately guys, this one one of my main production warehouse systems, so I cannot just get all users to log out....
There is no problem with either my logname or the Xtmp files (mentioned previously)

Thanks for the assistance, but this system will reboot tomorrow when everyone is asleep. (meaning the session I had will terminate) I'll keep an eye on it and see what happens next week. Unless somebody has something new to add, I'll consider this thread closed.
