Hi

Do you have access on the destination client (200.81.1.12) from your source server on port 1515.

actullay 200.81.1.12 (HP-UX server) is a server iam trying to connect from normal windows pc from command prompt.

and then i tried to connect another port 1055 it is connecting but when iam trying to connect 1515 i cant able.

what setting i have change in my server (200.81.1.12)

1515 port is used for catia application, from lan & wan i can able work catia application, from vpn i cant able to use catia

Hi

There may be a firewall between your windows machine & the server.
You need to take the firewall acces from your windows machine to the server on port 1515.

You can chk with your network team.

If u don,t mind

yes allready i told to our netwok & wan team they are blaming the problem with unix server. eventhough i added the port in /etc/services.

Thanks & Regds

Hello,

Do you have a station directly connected in the same LAN as your server? If the port would appear to be closed from this station, maybe you have a firewall on your HP-UX server.

Hi Horia.

iam not configured any firewall in server. see i can able to connect application through wan also one state to another state but i can't able to VPN

Did you checked your VPN settings? Maybe the VPN is blocking connections to that port.

What kind of VPN are you using?

I assume that that's Windows-speak for
"Connection refused", which would mean that
no one is listening at port 1515 on the
system at 200.81.1.12.

So, I'd guess that there's some part of
CATIA which you need to start/run.

Adding something to "/etc/services" will not,
by itself, cause any program to start
listening at any particular port.

Curiosity: What, exactly, did you add to
"/etc/services"?

Have you read the CATIA documentation? Did
it tell you to edit "/etc/services", or was
that your own idea?

It's a common misconception that adding
things to "/etc/services" does more than it
does. See, for example, the (unappreciated)
discussion at:

A quick Google search for
catia port 1515
suggests that this port is used by the CATIA
license server. Are you running the CATIA
license server? (I suspect not.)

Have you run
netstat -an
on the HP-UX system to see if anyone is
listening at port 1515?

Rajesh already told us on his second post that
from LAN he can use the application, so the daemon must be running and listening on the required port:
