 |
|
When I run this command:
sudo rdiff-backup --print-statistics --exclude-globbing-filelist
/home/bry/backup/vic/exclude --remote-schema 'ssh -C %s sudo
rdiff-backup --server' vic::/home /home/bry/backup/vic/home
I get the error:
ssh: Could not resolve hostname vic: Name or service not known
Fatal Error: Truncated header string (problem probably originated remotely)
Couldn't start up the remote connection by executing
ssh -C vic sudo rdiff-backup --server
However, when I run "ssh -C vic sudo rdiff-backup --server" manually,
it works fine. Why is it saying it can't resolve hostname vic:? I
have 'vic' setup in my .ssh/config file, and it works fine manually.
The only reason I am using --remote-schema is so I can stick the
'sudo' in there, because I need rdiff-backup to run as root on the
server so it can read all the files, and the root user is not
available in Ubuntu, so I have to use sudo.

In what .ssh/config have you set the hostname? In /home/you/.ssh/config or
/root/.ssh/config? When you use sudo you run the program as root, hence it will
look in the root home directory for user specific setting. Another option is to
use /etc/ssh/ssh_config, which then will apply those settings to every user on
the machine.
Also, an Ubuntu system very much has a root user. It is simply locked. If you
want to use it you can do so by giving it a password and/or an ssh public key.
