- We are experiencing strange behaviour with telnet and rlogin on an ESIX 4.0.4
- system. They appear to leave old entries lying around in the utmp file.
- For example
-
- $ who -a
- . system boot Jan 22 16:49
- . run-level 3 Jan 22 17:00 3 0 2
- rc2 . Jan 22 17:00 old 284 id= r2 term=0 exit=0
- ln . Jan 22 17:00 old 460 id= li term=0 exit=2
- sac . Jan 22 16:49 old 213 id= sc
- LOGIN console Jan 22 16:49 old 214
- inetd . Jan 22 16:49 old 215
- tcp . Jan 22 16:49 old 216
- pan pts/2 Jan 25 11:09 . 10899
- rc3 . Jan 22 17:00 old 394 id= r3 term=0 exit=0

- Note the lines ending id=tnNN or id=rlNN. These are old telnets and rlogins
- but they still appear to be active. The result is that some programs such as
- "who am i" or more importantly "passwd" can pick up the wrong entry in the utmp
- file and turn you into someone else
-
- I have checked another system running 4.0.3 and it seems ok. Does anyone know
- what could be causing the problem, and how to fix it.
