Access of Remote Unix server through X-Manager

[Ajay Kumar_5]

I want to access unix server which is at remote place and connectivity is through leased line. Ping response is 60 ms .
I want to access the server through X- Manager.
When we add the host ip in the x manager it takes the host name correctly but gives error XDMCP failed .The X - manager log shows that XDMCP Request is accepted but XDMCP manage message is timed out as shown below.

Xdmcp Request Address: 10.101.0.3
Xdmcp Connection Address 0: 10.250.2.32
Xdmcp: sent a REQUEST message
Xdmcp: received an ACCEPT message
Xdmcp: sent a MANAGE message.
Xdmcp: Timed out, state 8. Retransmissions: 0
Xdmcp: sent a MANAGE message.
Xdmcp: Timed out, state 8. Retransmissions: 1
Xdmcp: sent a MANAGE message.
Xdmcp: Timed out, state 8. Retransmissions: 2
Xdmcp: sent a MANAGE message.
Xdmcp: Timed out, state 8. Retransmissions: 3
XDM go to sleep: too many retransmissions

Please help on this.
Thanks and Regards

Hi Ajay,

Is there a firewall between you and the remote server...?

[Bharat Katkar]

Ajay,
As ANTUNES pointed out, i also suspect the same. In case you have Firewall or a Router with access lists applied in between, it might have blocked certain ports and you are not able to connect.

Hope that helps.

You try to telnet your server on the 6000 port. If that doesn't pass, X protocol will be blocked.

Another point is to try a connecton from the subnet where the server is.

Dear Antunes and all ,
Yes,there is a firewall but no Ports are blocked for us.Aslo we have 4 hp ux servers in same network , same subnet , we are able to connect 3 hp ux servers but not able to connect one hp ux server through x-manager.

The port 6000 is reserved for hp ux 11i so we can not use that port.

Thanks and Regards
Ajay

Forgot xdm (X-Manager)... You'll be better off with VNC (www.realvnc.com) or search for threads re: VNC on this forum -- someone was kind enough to post a custom compiled version for HP-UX.

Why VNC ? -- because it is thin and almost always allowed thorugh FIrewalls since it uses the very ports used by RAutil and Terminal Server.. it also offers the advantage of not being a network hog.

Hi Ajay,

You must have a difference between the 3 servers that accepts Xdmcp and the other one that doesn't accept in the same subnet...
