RPC error: unable to Send 1

[nepomuk]

Hi

I have a windows server environment (w2k) all running on networker 6.13. The only client in DMZ (behind) firewall can't be backed up anymore since some days.

Unsuccessfull savesets:
*client1: All 1 retry attempted
*client1: All nsrexec: authtype nsrexec
*client1: All savefs: RPC error: Unable to receive
*client1: All savefs: cannot retrieve client resources
savefs client1: failed

I configured the following ports to use:
Service Ports: 7037+ 7938
Connection Ports: 10201-10300
Then restarted networker on both sides

from Backupserver>rpcinfo -p client1
program vers proto port
100000 2 tcp 7938
100000 2 udp 7938
390113 1 tcp 7937
program vers proto port
100000 2 tcp 7938
100000 2 udp 7938
390113 1 tcp 7937

from client1> rpcinfo -p backupserver

390104 1105 tcp 8551
390104 1405 tcp 8558
390104 1705 tcp 8564
rpcinfo: can't contact portmapper: Remote system error - Connection timed out

from client1 and backupserver i can "telnet backupserver 7937".
From client1 and backupserver i can't "telnet backupserver 10201":
Connecting To backupserver...Could not open a connection to host on port 10201 : Connect failed

Checking the firewall showed that all ports from backupserver to client1 are open and all ports >1023 from client1 to backupserver are open too!


Any ideas?

This points to a name resolution problem. However, it could also be portmapper problem.

Which type of client is this? Windows XP/SP1? If so, there is a utility to reconfigure the client's firewall. Please have a look in the Tech Bulletins you will find on the web.

Client is w2k Server SP4.
After restarting networker on server and on client now backup works again.

But if I try to open the nwadmin or the recover GUI from the client I get:
recover: Cannot start session with server backupserver: Unable to receive

Any ideas?

FYI: I encounter this error lately and I found out that problem mounting the neccessary volume will result in this error. When i fixed the device/pools problem, the error was gone.

On a Windows machines, Select "start / programs / Legato Networker / Networker User" and do a right click on "Networker User" select "properties" you need to add "-s backup_server" on the "target" line at the end of the line. This will tell your client on which server to connect to.

"C:\Program Files\Legato\nsr\bin\winworkr.exe" -s backup_server_name
