In the example above 3 tables are copied. You can change the number of tables. You should be able to come up with variants of the command by modifying the mysqldump part easily, to copy some part of remote mysql DB.
This may be listed already but this command is useful to untar a specific directory to a different server.
If you are stuck behind a firewall and want to synchronize time with another server but you do not want to port forward NTP (which uses UDP) then this command is handy. It gets the time from a server and sets the local time. It is not that accurate but I can live with a second or so drift.
Run local scripts on remote server. "-T Disable pseudo-tty allocation"
1. SSH into a machine
2. Tunnels VNC port to your local computer ("-L 5900:localhost:5900")
3. Runs a single use vnc server ("x11vnc -safer -localhost -nopw -once -display :0")
4. Goes into the background ("-f")
5. Runs VNC viewer on the local computer connecting to the remote machine via the newly created SSH tunnel ("vinagre localhost:5900")
Will return the SSH server key information for each host you have in your ~/.ssh/known_hosts file, including key size, key fingerprint, key IP address or domain name, and key type.
This command will copy command's output into your local clipboard
- port 8080 on localhost will be a SOCKSv5 proxy
- at localhost:localport1 you will be connected to the external source server1:remoteport1 and at bind_address2:localport2 to server2:remoteport2
- you will be using only IPv4 and arcfour/blowfish-cbc, in order to speed up the tunnel
- if you lose the connection, autossh will resume it at soon as possible
- the tunnel is here a background process, wiithout any terminal window open
When debugging an ssh connection either to optimize your settings ie compression, ciphers, or more commonly for debugging an issue connecting, this alias comes in real handy as it's not easy to remember the '-o LogLevel=DEBUG3' argument, which adds a boost of debugging info not available with -vvv alone.
Especially useful are the FD info, and the setup negotiation to create a cleaner, faster connection.
When using tcpdump, specify -U option to prevent buffering.
This version transfers gzipped data which is unzipped as it arrives at the remote host.
use this command via ssh on remote machine when you want play video
remove --directory if you want select single file

~ is the ssh control character. If you type it after a newline, you can example force close the ssh session.
, ~, then .
If you want more info, type ~? when you are connecting using ssh.
Very useful to kill of any hanging ssh sessions when nothing else works.
The pee command is in the moreutils package.
Do the same as pssh, just in shell syntax.
Put your hosts in hostlist, one per line.
Command outputs are gathered in output and error directories.
This command will download $file via server. I've used this when FTP was broken at the office and I needed to download some software packages.
Ever wanted to stream your favorite podcast across the network, well now you can.
This command will parse the iTunes enabled podcast and stream the latest episode across the network through ssh encryption.
Stream OGG vorbis over ssh.
This one doesn't need to convert to wav.
This will allow you to convert an audio file to wav format, and send it via ssh to a player on the other computer, which will open and play it there. Of course, substitute your information for the sound file and remote address
You do not have to use paplay on the remote end, as it is a PulseAudio thing. If the remote end uses ALSA, you should use aplay instead. If it uses OSS, you should berate them about having a lousy sound system. Also, you're not limited to transmitting encoded as wav either, it's just that AFAIK, most systems don't come with mp3 codecs, but will play wav files fine.
If you know SoX is installed on the remote end and has mp3 codecs, you can use the following instead:
cat Klaxon.mp3 |ssh email@example.com play -t mp3 -
this will transmit as mp3. Again, use your specific information. if you're not playing mp3s, use another type with the -t option
