Not able to ping or connect to system with telnet or ssh

[Kaps_2]

Hello Everybody,

I have just now installed HP-UX 11.31 on a server, where I have given proper IP address and which also is on network.The problem is that I can connect to another system from this system using ssh ( also I can ping other system ) but when I am trying to ssh or telnet or ping this HP-UX system, I am unable to do.Any Idea abt this.Please let me know as early as possible.

Thanks,

Kapil

First point I would check is the IP config (address/mask/gateway).

[Jaime Bolanos Rojas.]

I agree it sounds like the system was misconfigured.

Please check to see if you can ping your local ip address when you are local to the system, also you might want to post your /etc/hosts file and see if you can ping any other hosts that might be listed there.

Regards,

Jaime.

Hi Tortson,

As i mentioned the IP address is proper.As now I am able to ping the system.But not able to ssh or telnet.Bastille is installed on the system.Will this create any problem...?

Thanks,

Hi,

do you ping with ip address or with name?
Maybe name resolution isn't working.

Hey Guys,

Now I am able to ping but not able to telnet or ssh that system...

[Torsten.]

If the IP address is OK, did you check gateway and mask too?

This does not describe the problem well.
Actual commands with actual error messages
would reduce the guesswork required.

no error msg getting while I am trying to do ssh or telnet..gateway is proper...is there any thing u know abt bastille...?

thanks,

What gives

# bastille -l

(lower case L)

[John Carr_2]

can you login into the destination server by any route nd talk back to the new server?

[Kaps_2]

Hi,

Is there any way to check the telnet service is running...? also to restart telnet service...

[Torsten.]

check bastille as advised.

check

ssh 127.0.0.1
or the ip address.

telnet may be disabled.

Hi Kapil,

Check the telnet and ssh services are running

Telnet
------------------
you should get similar output when you do
a grep of telnet in /etc/inetd.conf and /etc/services

# grep telnet /etc/services
telnet 23/tcp # Virtual Terminal Protocol
# grep telnet /etc/inetd.conf
telnet stream tcp6 nowait root /usr/lbin/telnetd telnetd


if they are commented, then uncomment them and run #inetd -c
now check # netstat -an|grep LISTEN|grep 21

you should see a port listinening ....

As for ssh,check the ssh daemon is up

SSH
---------------
ps -ef|grep -i ssh

then check the ssh config files
normally at /etc/ssh/...
or /opt/ssh/etc ...
you can do a find and see the ssh config files

find / -name sshd_config -print ...
man sshd_config ... will help you ..

try putting a minimal ssh config file

in sshd_config

------------------------------
Protocol 2
HostbasedAuthentication yes
KerberosAuthentication no
UsePAM no
X11Forwarding yes
Subsystem sftp /opt/ssh/libexec/sftp-server
---------------------------------

then restart ssh daemon ....

Kapil,

if you have Bastille,

The only way to get Bastille to loosen its security, is to revert the system to its "pre-Bastille" state with bastille -r, which essentially moves all the system files from the /var/opt/sec_mgmt/bastille/revert/backup directory structure back to their original location.

Now I am able to do ssh and telnet...but the server is now taking lot of time for responding....?

[Torsten.]

"Now I am able to do ping ..."

"Now I am able to do ssh and telnet ..."

[Torsten.]

Please post the steps you did here.

[Kaps_2]

Hi Torsten,

Yeah the other thread is related to this.Since yesterday I have just disable bastille by bastille -r.Other than that I have not done anything..but after that I am anle to ssh & telnet the system but its taking a long time to establish connection.So I want to know why its taking so long time.

Thanks,

Kaps

> [...] why its taking so long time.

The usual reason for a connection delay for
Telnet and SSH is a DNS problem. The servers
normally try to translate the client IP
address to a name, and that can take some
time if the DNS look-up fails.

On the server, try something like:
nslookup
If you don't get the client name quickly,
then that could be the problem.

This could all be much simpler if you would
simply tell us exactly what you did, and
exactly what happened when you did it.
