RedHat9 client backup fails-"No route to host"

[pinkmoon]

Win2k server, Redhat9 client.

Server can ping client and vice versa.

Using rpcinfo -p hostname client can view server, but server cannot view client. Instead query fails with "No route to host" error. Seems new Redhat version is blocking access. What can be done on client to allow Networker access please?

In general, this points to a name resoulution problem.

Will a manual save from the client work ?
Try to test this with added verbosity, for example:
save -s server -vvv /etc/hosts

This should tell you more.

RedHat9 seems to have almost all ports blocked which is preventing access. Seems I will need to open the necessary ports to allow access to the server.

Is there a list of ports Networker needs to have access to for backups and restores?

typically Networker uses:

Connection Ports: 10001 - 3000 (C)
Service Ports: 7937 - 9936 (S)

change this with nsrports -S <service-ports> -C <connection-ports>

Ports are covered in the Legato Admin Guide, Chapter 3, &quot;Firewall Support&quot;.

On a default install of RH 9.0 and WS 2.1/3.0 it will configure a firewall. The default configuration is to enable ssh,http and a few more ports.If you want to check it this is causing the problem, before enabling specific ports, you can do the following;

On the Linux box.

[root@linux root]# chkconfig --list iptables
iptables 0ff 1ff 2n 3n 4n 5n 6ff
[root@liux root]# chkconfig iptables off
[root@linux root]# chkconfig --list iptables
iptables 0ff 1ff 2ff 3ff 4ff 5ff 6ff

This checks if the firewall ( iptables ) is enabled. It then disables it and verifies that it has been turned off).

you also could try do completly disable the firewall.

run: setup --- from commandline and disable firewall-support for testing purposes
