Can I use rsync to move a list of files in different directories to a remote sever without logging in more than once?

So, I'm trying to write a script to back up some various configuration files with my ssh fileserver, but I'm not sure the best way to go about this. It would be nice if I could just fill a file with absolute file paths for both machines and directly do this with parallel or something. Parallel has a script that works for an individual directory, but I want to expand this to multiple locations.



For example:



/home/localuser/.bashrc --> remoteuser@remoteIP:/home/remoteuser/backup/.bashrc
/home/localuser/.config/i3/config --> remoteuser@remoteIP:/home/remoteuser/backup/.config/i3/config


for a multitude of files as well as going in the reverse direction if the server actually has a more recent copy.



remoteuser@remoteIP:/home/remoteuser/backup/.bashrc --> /home/localuser/.bashrc


I could effectively do this for one file using these two commands, but I'd have to log in twice.



rsync -vrut -e 'ssh -p portnumber' /home/localuser/.bashrc remoteuser@remoteIP:/home/remoteuser/backup/.bashrc

rsync -vrut -e 'ssh -p portnumber' remoteuser@remoteIP:/home/remoteuser/backup/.bashrc /home/localuser/.bashrc

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
