Hi, I have been trying to get BackupPC 3.3.2 running on a Debian 10/Buster server to back up my OpenBSD 6.6 router. It works fine with the GNU rsync port on the OpenBSD box but when I try to use the native openrsync instead, it just seems to not get started properly and hangs.
On the Debian side, it looks like this until I kill it after a few hours: $ /usr/bin/perl /usr/share/backuppc/bin/BackupPC_dump -v milan cmdSystemOrEval: about to system /bin/ping -c 1 172.16.10.1 cmdSystemOrEval: finished: got output PING 172.16.10.1 (172.16.10.1) 56(84) bytes of data. 64 bytes from 172.16.10.1: icmp_seq=1 ttl=255 time=0.173 ms --- 172.16.10.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.173/0.173/0.173/0.000 ms cmdSystemOrEval: about to system /bin/ping -c 1 172.16.10.1 cmdSystemOrEval: finished: got output PING 172.16.10.1 (172.16.10.1) 56(84) bytes of data. 64 bytes from 172.16.10.1: icmp_seq=1 ttl=255 time=0.094 ms --- 172.16.10.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.094/0.094/0.094/0.000 ms CheckHostAlive: returning 0.094 full backup started for directory / (baseline backup #135) started full dump, share=/ Running: /usr/bin/ssh -q -x -o UserKnownHostsFile=/etc/backuppc/ssh/known_hosts -i /etc/backuppc/ssh/id_ed25519 -l backup 172.16.10.1 doas /usr/local/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --times --recursive -x --ignore-times . / Xfer PIDs are now 10093 xferPids 10093 Got remote protocol 27 Negotiated protocol version 27 milan/172.16.10.1 is the OpenBSD box to be backed up. BackupPC connects via ssh and starts openrsync in server mode. /usr/local/bin/rsync is a wrapper script that removes the "--ignore-times" parameter before it invokes openrsync because openrsync does not understand that parameter and BackupPC insists on adding that parameter. On the OpenBSD box I see the following processes until I kill them after a few hours: USER PID PPID PGID SESS JOBC STAT TT TIME COMMAND backup 22274 23311 23311 fffffd8073138850 0 I ?? 0:00.12 sshd: backup@notty (sshd) backup 98017 22274 98017 fffffd80731388c0 0 Ip ?? 0:00.05 sh -c doas /usr/local/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --times --recursive -x --ignore-times . / root 95559 98017 98017 fffffd80731388c0 0 Ip ?? 0:00.01 /bin/ksh /usr/local/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --times --recursive -x --ignore-times . / root 15271 95559 98017 fffffd80731388c0 0 IpU ?? 0:00.28 /usr/bin/openrsync --server --sender --numeric-ids --perms --owner --group -D --links --times --recursive -x . / A ktrace -dig 98017 just gives me an empty trace file (it starts to have something when I kill the processes but that obviously does not tell me what went wrong initially). Any suggestions what might go wrong or how to debug this further? Fabian
