telnet problem in 11i

[Gopinath_3]

I installed hp-ux 11i on a N4000 machine without any errors. telnet to and from the machine was working fine. I then installed the GOLDBASE11i & GOLDAPPS 11i patch bundles. Since then telnet (even to the same machine) gives this error:
telnet: tcp/telnet: unknown service.

There is an uncommented entry for telnet in /etc/services, its permissions are 444 (I have tried other perms too) and there is no deny for telnet in /var/adm/inetd.sec

I removed the two patch bundles but I still cant get telnet to work. I can ping to other machines on the NW but neither telnet/rlogin work either way.

Thanks

What about the /etc/inetd.conf file. Is telnet commented out of there? This only matters on inbound connections, using telnetd.

Outbound uses the telnet command, what are the permissions on those two files as well.

Let us know,

Hi Gopi,

Take a look at the thread below,

Hope this helps.

Gopi,
Another option is presented in this thread. Similar to the thread given by Sanjay, although you said you have already checked /etc/services.

Good Luck,
C

hi,


If your problem is not being
able to telnet into the system from another box or even from the same box, the problem has to be with one of:
**/etc/services
** /etc/inetd.conf

do a grep telnet /etc/inetd.conf and see what the entry is.

Also check /var/adm/inetd.sec and see whether there is any deny entry for telnet in it.

Does the same problem occur with ftp or rlogin??

HTH and don''t forget to inform us how it got working.
(it sure will!)

Hi,

Check your /etc/nsswitch.conf file.

Hi,

iF you problem is with telnet itself: then
***
On Problemsystem
telnet testsystem
-> does this work??
If it does not, then check the telnet binary:
#which telnet
#ll `which telnet`
#what `which telnet`
-> make sure the size and versions of the binary is correct. (compare it with a working box).

Sanjay's pointer helped.

There was no nsswitch.conf. I copied the hp_defaults file and modified it for my env. I can telnet out but not in.

telnetd has 544 perms and is owned by bin:bin

telnet is not commented out in /etc/inetd.conf

[Gopinath_3]

works fine now. I had to modify nsswitch.conf for my env, rebooted and telnet works fine both ways.

Thanks for the help
