situation: one is userA but wants to ssh login to server with ipv4: 220.127.116.11 via userB (dedicated user for that server/task).
so what one does is:
- make sure one can login as userB
than as userA:
userA: ssh -v -i /home/userB/.ssh/id_rsa userB@18.104.22.168
one will be asked for the passphrase of the ssh-key of userB and voila!
logged in! 🙂
this also works with scp: (uploading files as root from crontab as different user)
scp -v -i /home/user/.ssh/id_rsa /file/to/upload.txt firstname.lastname@example.org:/upload/path/
PS: REALLY REALLY LOVE OPENSSH! GREAT JOB ALL INVOLVED! 🙂
it’s usefull for SOOOO many things not only:
- remote administration of servers
- secure file-transfer / rsyncing files
- vpn like: tunneling ports and traffic
