Hello,
While running BackupPC 3.2.1 (CentOS), I found I can't set up backups
for a host that can't be reached via ICMP Ping.
I have hping installed, and modified default PingCmd for the host in
question with
/usr/bin/sudo /usr/sbin/hping $host -p 80 -c 1 -S
When I run it under backuppc user, it runs normally and returns with
exit status 0 ("echo $?" under /bin/bash). However, when I attempt
backup creation, I get something like
2019-10-16 12:44:37 no ping response
in it.
The manual run output looks like this:
----- output below
$ /usr/bin/sudo /usr/sbin/hping example.com -p 80 -c 1 -S
HPING example.com (eth0 93.184.216.34): S set, 40 headers + 0 data bytes
len=46 ip=52.34.179.106 ttl=36 DF id=0 sport=80 flags=SA seq=0 win=26883
rtt=239.1 ms
--- example.com hping statistic ---
1 packets tramitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 239.1/239.1/239.1 ms
----- output above
I would appreciate a hint on what I am doing wrong. Thank you.
Sincerely,
Konstantin
