You can use $Conf{ClientNameAlias} to point multiple hosts to the same

Yes, this works so long as I override the RsyncSshArgs in the host
config to include the correct port.

Re: [BackupPC-users] PingCmd no longer having effect
Thank you! You're completely right. When it says
2024-04-05 15:28:10 Can't find host myhost.com via NS and netbios
2024-04-05 15:28:10 can't ping (client = myhost.com); exiting
It seems like the first line is the real failure, and the ping is never
attempted.
Apologies for the list to cutting the log entry too short in my original
post.
I guess this is my fault due to my setup. I have several systems at a
single dynamic ip. I have backupPC set up like so:
host1.myhost.com
host2.myhost.com
host3.myhost.com
...
The backuppc user's ssh config file has each of those hosts configured
with different ports:
Host host1.myhost.com
Hostname myhost.com
Port 1
User root
Host host2.myhost.com
Hostname myhost.com
Port 2
User root
Host host3.myhost.com
Hostname myhost.com
Port 3
User root
...
This way the backuppc user can ssh host3.myhost.com and be logged in to
the proper system automatically.
I guess now my goal is to find out how to make backuppc bypass the dns
check, or to check myhost.com instead of hostx.myhost.com.
Though perhaps I'm way off base and there's a better way of configuring
all of this.

Have you tried adding an entry to your hosts file just to get past
this and allow further troubleshooting?

Pretty sure, 'which true' returns '/usr/bin/true'. Though, on my
system
true also exists at /bin/true, so I tried that as well just now.
Same
result.
I've also tried placing scripts in the PingCmd field and they do not
appear to execute.
Thanks,
Ian

Thanks for the idea, unfortunately same result.
2024-04-05 15:28:10 Can't find host myhost.com via NS and netbios
2024-04-05 15:28:10 can't ping (client = myhost.com); exiting
I also tried this
$Conf{PingCmd} = '/var/lib/backuppc/test.sh';
Where test.sh is +x and contains
#!/usr/bin/bash
echo `/usr/bin/date` >> /var/lib/backuppc/testlog.txt
After restarting backuppc (and the whole server for good measure, since
this problem is starting to feel weird), I tried backing up that host.
No output in the text file.
However using sudo to execute the file as backuppc user works as expected.

[BackupPC-users] PingCmd no longer having effect
Hi,
I've been using BackupPC for many years now, and have used /usr/bin/true
as the ping command for hosts that can't respond to ping. However after
a reboot on January 31st, my server stopped obeying pingcmd and stopped
backing up those hosts due to lack of ping response. I am using
BackupPC 4.4.0-5ubuntu2 amd64 on Ubuntu 22.04.
So far I have tried:
Overriding $Conf{PingCmd}, $Conf{PingPath}, and $Conf{Ping6Path} in the
global config from webui and config file.
Setting $Conf{PingCmd} in the client config to either /usr/bin/true or
ping -c1 127.0.0.1 using webui and config file.
None of the above seem to make any difference at all anymore. No matter
what I set, I restart the service and get the same error:
2024-04-05 13:58:38 can't ping (client = myclient.com); exiting
However I can confirm other changes to the client config files do have
an effect. For example setting a ClientNameAlias in the client config
works.
I also tried deleting the client config file and allowing the webui to
create it, and doing an apt-get --reinstall install backuppc. Same effect.
I'm wondering if anyone has noticed anything similar, or has advice on
how to debug.
Thanks,
Ian___
