Useful to move many files (thousands or millions files) over ssh. Faster than scp because this way you save a lot of tcp connection establishments (syn/ack packets).

If using a fast lan (I have just tested gigabyte ethernet) it is faster to not compress the data so the command would be:

tar -cf - /home/user/test | ssh user@sshServer 'cd /tmp; tar xf -'

I have a small embedded linux device that I wanted to use for sniffing my external network, but I didn't want to recompile/cross-compile snort for the embedded platform. So I used tcpdump over ssh to pass all the traffic as pcap data to a "normal" Linux system that then takes the pcap data and passes it to snort for processing.

Locally watch MySQL process list update every 5s on a remote host. While you watch pipe to a file. The file out put is messy though but hey at least you have a history of what you see.

If you know the benefits of screen, then this might come in handy for you. Instead of ssh'ing into a machine and then running a screen command, this can all be done on one line instead. Just have the person on the machine your ssh'ing into run something like

screen -S debug

Then you would run

ssh -t user@host screen -x debug

and be attached to the same screen session.

This will launch and irssi session on your server. If it's not running, it will create the session. If it's running it'll connect to it and destroy any other connections. If compositing is available, the rxvt window will have transparency added. This window will also open maximized. Anything else this does should be easily figured out in the man pages.

Knock on ports to open a port to a service (ssh for example) and knock again to close the port. You have to install knockd.

See example config file below.

[options]

logfile = /var/log/knockd.log

[openSSH]

sequence = 3000,4000,5000

seq_timeout = 5

command = /sbin/iptables -A INPUT -i eth0 -s %IP% -p tcp --dport 22 -j ACCEPT

tcpflags = syn

[closeSSH]

sequence = 5000,4000,3000

seq_timeout = 5

command = /sbin/iptables -D INPUT -i eth0 -s %IP% -p tcp --dport 22 -j ACCEPT

tcpflags = syn

Requires Linux Remind:

and Growl on the Mac:

http://growl.info/

growlnotify needs to be in the executable path on the mac.

Combined with "prowl" in the iPhone you can receive push notifications of your reminders to the iPhone.

Redirects the contents of your clipboard through a pipe, to a remote machine via SSH.

this bzips a folder and transfers it over the network to "host" at 777k bit/s.

cstream can do a lot more, have a look http://www.cons.org/cracauer/cstream.html#usage

for example:

echo w00t, i'm 733+ | cstream -b1 -t2

hehe :)

Thankfully, the ssh command allows you to specify multiple tunnels through the same server in one command.

Remeber if you want a priviliged port on your machine, you must use root or sudo account.

If your firewall or proxy at your location prevents connection to a particular host or port, you can use ssh to tunnel to your home server and do it there instead.

Run GUI apps on another machine remotely through SSH.

-C is for data compression and -X enables X11 forwarding.

And then to complete the task:

Go to target host;

ssh host

Turn everything off:

for i in `chkconfig --list | fgrep :on | awk '{print $1}'` ; do chkconfig --level 12345 $i off; done

Create duplicate config:

while read line; do chkconfig --level $line on; done < foo

Optionally, you can create a new function to do this with a custom command. Edit $HOME/.bashrc and add:

myssh () { ssh $1 | tee sshlog ; }

Save it.

At command prompt:

myssh user@server

This command will copy files and directories from a remote machine to the local one.

Ensure you are in the local directory you want to populate with the remote files before running the command.

To copy a directory and it's contents, you could:

ssh user@host "(cd /path/to/a/directory ; tar cvf - ./targetdir)" | tar xvf -

This is especially useful on *nix'es that don't have 'scp' installed by default.
