Re: ftp, ssh

Able to login from MP doesn't mean you have a network connection to the system. When you try to ping the system, what does there response it says?

Three possible causes. There is no connection to the remote site. Or the gateway setting is wrong from either your one server or the remote server. And last but not the least, you can not get a correct IP address of the remote site.

Is it running? Is it connected to the
network? Are you sure that you're using the
right IP address?

> but I can login from MP...

Does that mean that you can log into the MP,
or that you can log into HP-UX on the system?
Serial port on the MP, or Telnet, or what?

As usual, showing actual commands with their
actual output might be more helpful than
vague descriptions and interpretations.

> how to go about it

Start with a better description of the
situation. Then check the obvious things.

Some description of "my server" might also be
of some value to those of us who can't see
it.

Re: ftp, ssh

well I have rx7640

I can login remotely to MP and from there I login to the console..

Pinging 147.22.41.125 with 32 bytes of data:
Request timed out.

I have the IP address set up in /etc/hosts & rc.config.d/netconf

what else should I look for to login remotely.

Re: ftp, ssh

Once logged into the system via the console can you: ping your default gateway? ping other system? telnet/ssh to other systems?

Have you verified that networking is set up correctly on the server?

I'm wasting my e-breath, I can tell.

> [...] from there I login to the console..

What, exactly, does this mean? Are you
logging into HP-UX, or talking to the system
console, or what? From your description, I
don't even know if the system has been
powered on yet.

> Pinging 147.22.41.125 with 32 bytes of data:

And you did this where? And who is
147.22.41.125?

> I have the IP address set up in /etc/hosts
> & rc.config.d/netconf

I should trust your opinion?

> what else should I look for to login

What _else_ other than what? What have you
checked up to now? Is the network cable
plugged in?

Provide some basic info, or else you might do
better if you called a psychic hot-line.

Re: ftp, ssh

I guess networking is not set up correctly on the server ... as I cannot ping to other server/telnet to ther servers

That would do it.

I'm not sure what you are trying to show with this. All this proves is that you can ping to loopback address. This shows that the IP stack is working, but nothing else.

If you want additional help, things like:

output of 'netstat -in'
output of 'netstat -rn'
output when you try to log into or ping some other host

will be extremely helpful.

Re: ftp, ssh

steven,

system is powered on

147.22.41.125 is the IP address of the server of which i am talking on

>>What, exactly, does this mean?

means like log on to Mp to access the OS


147.22.41.125 hp01.hp.com
127.0.0.1 localhost loopback


Cables are all connected properly... Networking has not been done from the OS side

Re: ftp, ssh

OK. That's a start. Now for some additional information:

output from 'ifconfig lan0'
output from 'ping 147.22.41.1'

The error you give seems to indicate that there is no route available to the 147.22.41 network, even though the host you are trying to access APPEARS to be on the same subnet, assuming a 255.255.255.0 subnet mask.

Are you ABSOLUTELY POSITIVE that you have connected the cable to the LAN0 network port?

NOTE: The LAN0 network port is DIFFERENT from the MP network port. If you only have 1 cable plugged into the back of the server, and you are accessing the MP from the network, then that is your problem.

So, as I see it, "netstat -in" says that lan0
is 147.22.41.125, while "ifconfig" says that
lan0 is 147.22.41.124.

Someone's confused. (I certainly am.)

Are you willing to show the evidence?

Do these commands do anything different
after a re-boot?

Re: ftp, ssh

Get your target system gateway address, then try to ping it from your system.

Re: ftp, ssh

I have the same issue on my other server B..

On this from thee outside world I can ping my gateway..

I have two lan's configured here..

lan0 & lan1

I can ping the gateway for lan1 but lan 0 I cannot...

Re: ftp, ssh

Then try to telnet to your lan1.
