login not possible

Ionut Grigorescu_2 — Tue, 21 Dec 2004 01:34:50 GMT

Hi all,

since yesterday I have no more a login prompt to a HP-UX 11.00 box when using telnet/ssh - I still can rlogin from another box in the same NIS domain but no more directly from my workstation or any other box outside this NIS domain - and I have no clue what should be the cause for this... any idea? - when I try a telnet session it simply hangs, only the CTRL ] sequence can close the session, no login prompt appears... I couldn't find anything in the logs.

Thanks in advance,
ionut

check /var/adm/syslog/syslog.log and check as whether the telnet sessions have gone above the max kernel limit.

Hi,

there are only timeout entries in syslog related to telnet - the same behaviour is also for ssh...

Hi Ionut Grigorescu

I think first, you should try to reboot the inetd daemon (inetd -c).
Second, you should check in the /var/adm/inetd.sec file.
May be someone change and disable the telnet service permission!
Add one more line like this:

telnet allow

then reboot the inetd daemon.
I think it works!

Best and regard,

Hi Hoang,

nobody changed the permissions on my box, and I have no inetd.sec - If I would I should receive something like "connection closed" when trying to telnet, shouldn't I? It simply doesn't prompt me to login, it makes me crazy...

Hi,

everything I have done was editing named.conf, resolv.conf and adding some zone files to /var/named in order to prepare the box for beeing a name server for the application which will run on it. I still haven't started named on it so everything should be as before. On the box is running MC/Service Guard and one of the packages is the NIS+NFS server. There are 2 MC/SG packages running on it and there is another server running the database package - both are building up a cluster. In the same NIS domain there are 3 other HP workstations - I don't know if that helps.

Hi ionut,
Can u doi one thing.. do rlogin to your box and then :

# telnet boxname

Try doing telnet from the box to box itself.
See if that works?

I ahve choosed from the thread you've mentioned the quick and "dirty way" - I've added the IP address of the box from which I'm telnet-ing to the /etc/hosts on the HP box. The problem were of course the new entries in resolv.conf
Thanks a lot
