Refusing to find client on server end

client
1

I can’t quite work this one out. I have 3 servers. Running:

south.x = ubuntu 20.04
west.x = ubuntu 18.04
admin.x = ubuntu 16.04 (I’m phasing this one out, but still need it backed up :slight_smile:

This is what I see in my server’s GUI:

On the client IP (213.219.38.x), I can see its listening on the ports:

netstat -tulpn | grep 3562
tcp        0      0 0.0.0.0:35621           0.0.0.0:*               LISTEN      14953/urbackupclien
tcp        0      0 0.0.0.0:35623           0.0.0.0:*               LISTEN      14953/urbackupclien

tcp6       0      0 :::35623                :::*                    LISTEN      14953/urbackupclien

…and this is what I have on one of the servers that is working:

tcp        0      0 0.0.0.0:35621           0.0.0.0:*               LISTEN      569/urbackupclientb

tcp6       0      0 :::35621                :::*                    LISTEN      569/urbackupclientb
tcp6       0      0 :::35623                :::*                    LISTEN      569/urbackupclientb
udp        0      0 0.0.0.0:35622           0.0.0.0:*                           569/urbackupclientb
udp6       0      0 :::35622                :::*                                569/urbackupclientb

What else could be stopping it from working? I’m at a bit of a dead end :frowning:

Thanks in advance

Man I’m still having issues :frowning:

The backup server pings:

ping 194.29.101.139
PING 194.29.101.139 (194.29.101.139) 56(84) bytes of data.
64 bytes from 194.29.101.139: icmp_seq=1 ttl=58 time=0.888 ms

Yet when running from the client server, I get:

urbackupclientctl start -i
Error starting backup. No backup server found.

Yet as you can see, it was working fine this morning, and did backups for both servers?

Eugh now I feel like a muppet!!!

Its important to have the right ports, with UDP and TCP setup as per that list. For my server, I set the client IP’s to only allow from my backup server (as that’s the only one that should be requesting). Also you need to lock down the the admin panel port to make sure no nasties can get in and grab your data

ARGH I feel so stupid for wasting so much time and not checking out that article!
