Another session logged in but running no processes?

asimov · 01-30-2011, 06:49 AM

Hi all,

Since I can't figure what's going on, any hint would be appreciated.

My University gives us access to a Linux server, named stud1.

Code:

me@stud1:~$ uname -a
Linux stud1.some.univ.ac 2.6.9-89.31.1.ELsmp #1 SMP Mon Oct 4 21:41:59 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

Apparently I was logged in, and never logged out sometime:

Code:

me@stud1:~$ who
<snip>
me       pts/37       Jan 30 13:27 (6.6.66.66)
<snip>
me       pts/58       Dec 30 19:13

but when trying to find out why I'm still logged in, I can't find it:

Code:

me@stud1:~$ ps faux |grep me
root  30030  0.0  0.0 51128 4360 ?        Ss   13:27   0:00  \_ sshd: me [priv]
me    30033  0.0  0.0 51132 2336 ?        S    13:27   0:00      \_ sshd: me@pts/37
me    30034  0.0  0.0 59684 1536 pts/37   Ss   13:27   0:00          \_ -bash
me    31241  0.0  0.0 10732 1248 pts/37   R+   13:45   0:00              \_ ps faux
me    31242  0.0  0.0 51084  584 pts/37   S+   13:45   0:00              \_ grep --color=auto me

My question is: what is going on? how can I logout this unused session?

Thanks in advance.

Can you kill the bash terminal associated with it?
the o/p of lsof |grep me might also be interesting

how can I kill the terminal? the mysterious pts is not even showing in /dev:

Code:

me@stud1:/dev/pts$ ls
0  101  120  136  137  14  23  25  26  28  29  33  35  36  37  39  44  48  5  56  64  77  8  84  85  87  88  89  92

Code:

me@stud1:~$ lsof |grep me
