Chris's questions

I have a script that runs on the host and creates/starts/stops a docker container. I'd like the script to change the password of the root user within the container.

Since the container is an ssh server, I tried: sshpass -p 'OLDPASS' ssh root@<container-IP> 'echo -e "NEWPASS\nNEWPASS" | passwd root'

but it doesn't work. Before going ahead and spending more time debugging it, I'd like to know if there's a smarter way to do it.

I understand that the proper "docker way" is to make a script that is run by the Dockerfile, which pulls the password from a shared volume and sets it as the root password. This sounds complicated, but I know how to do it and works well for another docker image I use. But I don't want to do it for this one.

I just need a command that uses Docker or ssh to change a user's password non-interactively.

BackupPC works good on my LAN but has problems backing-up a remote server of mine. I'm using rsync over ssh and have increased max ping to 500 because the remote server is far away.

Here is my error log (user and 1.2.3.4 are masked info):

full backup started for directory / Running: /usr/bin/ssh -p 2222 -q -x -l user 1.2.3.4 /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --ignore-times . /

Saving this as a partial backup

Trying to ssh as user backuppc to remote server works without asking a password. The general LOG is like this:

Almost always ending after 1h01'or 1h02'. These values in seconds are 3660 and 3720. Maybe they appear in some option...? Any remarks?

Thanks

EDIT: What I've tried and didn't work: - ServerAliveInterval=300, ServerAliveInterval=60 - increased PingMaxMsec to 500 - rsync options --timeout and --contimeout set to 20 and 200 seconds (both values tried on both options) - removing block-size option from rsync

Nothing worked. It usually stops in different files, independently of their size.

NEW EDIT: If I manually login to this remote ssh server, and leave my terminal untouched for 1h26" I get disconnected. Looks like this is the reason BackupPC gets disconnected, too. Is there any way to simulate the execution of commands inside BackupPC's session?
