Linux SCP – Use Special Username

linuxscpshell

I'm trying to create a shell script for copying files to a remote backup.

This is my script so far:

PASSWORD=MY-SECRET-PASS
URL=SLOS755513-3:SL1255513@objectstorage.net
DIR=/backup

scp /home/user/my_log.txt $URL:$DIR

But I'm getting the error:

ssh: Could not resolve hostname SLOS755513-3: Name or service not known
lost connection

I guess it's because of the special characters in the username, because if I simply write test instead it actually tries to connect with test as user.

But I've tried to escape \- and \: and everything gives me the same error.
I'm also unsure how to use the password in the script.

Try something like this:

RUSER='SLOS755513-3:SL1255513'
HOST=objectstorage.net
DIR=/backup

scp -o user=$RUSER /home/user/my_log.txt $HOST:$DIR

This will make the user part explicit so scp doesn't try to interpret : as host/path separator. -o user=$USER will send the user as an option to the underlying ssh.

Bash – Variable directory names over SCP

Run a similar version of the earlier script on the source server using cron, where it archives and encrypts all the files to a directory. At an appropriate interval following that, have a cron on the target server rsync over SSH that location. You could scp but rsync has many advantages.

Otherwise, I'd scrap your requirements and run an on-demand hybrid solution from the target using SSH pipes.

Determine if the “yes” is necessary when doing an SCP

man ssh_config

"... StrictHostKeyChecking If this flag is set to yes'', ssh(1) will never automatically add host keys to the ~/.ssh/known_hosts file, and refuses to connect to hosts whose host key has changed. This provides maximum protection against trojan horse attacks, though it can be annoying when the /etc/ssh/ssh_known_hosts file is poorly main‐ tained or when connections to new hosts are frequently made. This option forces the user to manually add all new hosts. If this flag is set tono'', ssh will automatically add new host keys to the user known hosts files. If this flag is set to ask'', new host keys will be added to the user known host files only after the user has confirmed that is what they really want to do, and ssh will refuse to connect to hosts whose host key has changed. The host keys of known hosts will be verified automatically in all cases. The argument must beyes'', no'', orask''. The default is ``ask''. ..."
