Commands using ssh from sorted by
Terminal - Commands using ssh - 295 results
cat .ssh/id_rsa.pub | ssh hostname 'cat >> .ssh/authorized_keys'
2009-02-11 17:40:12
User: bendavis78
Functions: cat hostname ssh
14

Just run the command, type your password, and that's the last time you need to enter your password for that server.

This assumes that the server supports publickey authentication. Also, the permissions on your home dir are 755, and the permissions on your .ssh dir are 700 (local and remote).

dd if=/dev/zero bs=1M | ssh somesite dd of=/dev/null
while [ ! -f /tmp/stop ]; do ssh -o ExitOnForwardFailure=yes -R 2222:localhost:22 target "while nc -zv localhost 2222; do sleep 5; done"; sleep 5;done
diff <(ssh nx915000 "rpm -qa") <(ssh nx915001 "rpm -qa")
echo -n m{1..5}.cluster.net | xargs -d' ' -n1 -P5 -I{} ssh {} 'uptime'
dd if=/dev/dsp | ssh -c arcfour -C username@host dd of=/dev/dsp

Functions: dd ssh

This will output the sound from your microphone port to the ssh target computer's speaker port. The sound quality is very bad, so you will hear a lot of hissing.

tar -cvzf - /source/path | ssh <targethostname> -l <username> dd of=/destination/path/backupfile.tgz
2009-02-06 15:52:09
User: smm
Functions: dd ssh tar
1

Creates a quick backup with tar to a remote host over ssh.

ssh -N -L2001:localhost:80 -o "ProxyCommand ssh someuser@hubmachine nc -w 5 %h %p" someuser@destinationmachine
2009-02-06 09:58:08
Functions: ssh
4

this is handy when the hubmachine is the only machine that can connect to the destination machine (allowed on ip by firewall) and you want to access it from your laptop.

cat ~/.ssh/id_rsa.pub | ssh user@machine "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys"

If you use Mac OS X or some other *nix variant that doesn't come with ssh-copy-id, this one-liner will allow you to add your public key to a remote machine so you can subsequently ssh to that machine without a password.

ssh-keygen -l -f [pubkey] | awk '{print $2}' | tr -ds ':' '' | egrep -ie "[a-f0-9]{32}"
ssh-keygen -i -f $sshkeysfile >> authorized_keys
dump 0f - / | bzip -c9 | ssh user@host "cat > /home/user/root.dump.bz2"
2009-02-05 17:22:32
User: wwest4
Functions: dump ssh

...can do similar w/ tar, dd, xfsdump, e2fsdump, etc.

vimdiff tera.py <(ssh -A testserver "cat tera.py")
ssh-keygen -R \[localhost\]:8022

User: Sekenre
Functions: ssh ssh-keygen

Useful if you have to tunnel ssh through a local port and it complains of the host key being different. Much easier than manually editing the file.

ping localip -c 1 -W 1 &> /dev/null && ssh localip || ssh globalip
2009-02-05 10:40:26
User: trey
Functions: ping ssh
1

Ping machine once, waiting 1 second for response until failing. Upon fail, ssh globally, otherwise ssh locally.

ssh -N -L2001:localhost:80 somemachine
ssh somemachine "cd some dir; tar zcpf - somedirname" |tar zxpf -
ssh user@host cat /path/to/remotefile | diff /path/to/localfile -
2009-02-04 11:33:19
User: root
Functions: cat diff ssh
148

Useful for checking if there are differences between local and remote files.

tar czv file1 file2 folder1 | ssh user@server tar zxv -C /destination
2009-01-29 10:38:26
User: xsawyerx
Functions: ssh tar
13

it compresses the files and folders to stdout, secure copies it to the server's stdin and runs tar there to extract the input and output to whatever destination using -C. if you emit "-C /destination", it will extract it to the home folder of the user, much like `scp file user@server:`.

the "v" in the tar command can be removed for no verbosity.

ssh user@host "ps aux | grep httpd | wc -l"
2009-01-27 00:46:17
User: root
Functions: ssh

This counts the number of httpd processes running.
