Your rule is incorrect. I'll quote myself:
> iptables -I INPUT -s client_addr -d backuppc_server_addr -p tcp --sport 22
For INPUT to the BackupPC server, it's --sport, not --dport that you want to
set. It's the other end that has port 8876. On the initiating side (BackupPC
server), a random port is allocated. If your remote side happens to be the
BackupPC server, too, then you're simply measuring the wrong way around (swap
INPUT and OUTPUT), otherwise you're measuring something arbitrary (you
obviously are measuring something).
So, change --sport to --dport and vice-versa.
> iptables -I INPUT -d localhost -p tcp --dport 8873
should be
> iptables -I INPUT -d localhost -p tcp --sport 8873
Aside from that, the "-I" was meant to insert the rule at the top, regardless
of what other rules you might have (you might do this in DumpPreUserCmd). If
you're just setting up static rules, you can use "-A" instead to keep them in
the order you're adding them (and you don't have any other rules that would
cause the accounting rules not to be reached).
