Problem in TELNET

[Shyam Sundar]

Hi,

In our HP9000 D270 running HP-UX 11.00 32 bit, we have a problem with telnet.

When we do telnet to this box, it gets disconnected automatically. But we are able to ping to that system.

Similarly, from the D class host we are able to ping to all other hosts in the network, but when we do telnet to any hosts, it comes out with BUS ERROR.

We had stopped and started the "inetd" services, made lan card down and up, and finally rebooted the system also. But still the problem persists.

Not able to trace anything in "dmesg" and in "syslog.log" also.

Could anyone help me out on this?.

Thanks and Regards,
Shyam

When do you get disconnected:
before or after entering username/password?

Did you check /var/adm/inetd.sec?

When do you get your disconnects,
before or after entering username/password?

Check also /var/adm/inetd.sec

Hi Hartmut,

Thanks for ur reply.

Disconnection is happening before Username/Password.
Had already checked inetd.sec and nothing to do with that.

Shyam.

Turn connection logging on for inetd with "inetd -l". Check syslog.log again.

Can you make ftp and rlogin connections to you host?

Is telnet listening on its socket? What do you see with:
netstat -a | grep telnet

Also what is the exact message you see when you are disconnected (on the incoming telnet)?

On the outgoing telnet problem: Can you FTP out or does that give you a bus error too? What does:
lanadmin
lan
display
show?

netstat -s?

netstat -a?
