Telnet access is not available anymore

Hi Folks,

My telnet access to the server is not available anymore. I have found that when I execute >telnet IP, the login prompt for username/password entry is not displayed. Cursor blinks in a empty line and I dont see the prompt to enter my username.
It hungs in this state and not possible to ctrl+c

When I try this, following process appears in
Code:
>ps -ef
 
root      9719     1  0 Aug03 ?        00:00:00 login -h xx.xx.xx.xx -p

In ps -ef list, similar processes are present and are not being cleared.
I tried to kill them without success by >kill -9 PID

I checked the messages log and found those logs,. I am able to ssh the same server

Code:
Aug 03 11:33:50 eqm01s14p2 sshd[26726]: error: PAM: Authentication failure for COC3110 from xx.xx.xx.xx
Aug 03 11:33:55 eqm01s14p2 sshd[26726]: error: PAM: Authentication failure for COC3110 from xx.xx.xx.xx
Aug 03 11:35:28 eqm01s14p2 sshd[27196]: (pam_unix) check pass; user unknown

Aug 03 11:35:37 eqm01s14p2 sshd[27205]: (pam_unix) check pass; user unknown
Aug 03 11:35:39 eqm01s14p2 sshd[27192]: error: PAM: User not known to the underlying authentication module for illegal user kory from xx.xx.xx.xx

How I can solve this telnet problem?
Thanks,
Kory

Nobody has any idea?
What I can do for those processes? Also If I can killl them somehow, would it be possible to telnet ?

Code:
root     27357     1  0 Aug01 ?        00:00:00 login -h 10.141.100.38 -p
root     27619     1  0 Aug01 ?        00:00:00 login -h 10.141.100.38 -p
root     27961     1  0 Aug01 ?        00:00:00 login -h 10.201.10.23 -p
root     28000     1  0 Aug01 ?        00:00:00 login -h 10.141.100.40 -p
root     28009     1  0 Aug01 ?        00:00:00 login -h 10.201.10.23 -p
root     29138     1  0 Aug01 ?        00:00:00 login -h 10.141.100.38 -p
root       477     1  0 Aug01 ?        00:00:00 login -h 10.210.20.27 -p

telnet has an escape character for a command mode where you can kill it.

Which host is which ps and log from, telent client or target server?
