Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

That's the easiest way to do it. -I (or capital i) display all network addresses of a host

echo -e '#!/bin/bash\nssh [email protected] $0 "$@"' >> /usr/local/bin/ssh-rpc; chmod +x /usr/local/bin/ssh-rpc; ln -s hostname /usr/local/bin/ssh-rpc; hostname

It's useful mostly for your custom scripts, which running on specific host and tired on ssh'ing every time when you need one simple command (i use it for update remote apt repository, when new package have to be downloaded from another host).

Don't forget to set up authorization by keys, for maximum comfort.

hostname -I
[ $1 == "client" ] && hostname || cat $0 | ssh $1 /bin/sh -s client

Now put more interesting stuff on the script in replacement of hostname, even entire functions, etc, and stuff.

hosta> cat myScript.sh


[ $1 == "client" ] && hostname || cat $0 | ssh $1 /bin/sh -s client

hosta> myScript.sh hostb



AUTOSSH_POLL=1 autossh -M 21010 hostname -t 'screen -Dr'
2009-10-11 06:04:29
Functions: hostname

Only useful for really flakey connections (but im stuck with one for now). Though if youre in this situation ive found this to be a good way to run autossh and it does a pretty good job of detecting when the session is down and restarting. Combined with the -t and screen commands this pops you back into your working session lickety split w/ as few headaches as possible.

And if autossh is a bit slow at detecting the downed ssh connection, just run this in another tab/terminal window to notify autossh that it should drop it and start over. Basically for when polling is too slow.

kill -SIGUSR1 `pgrep autossh`

dhclient -r && rm -f /var/lib/dhcp3/dhclient* && sed "s=$(hostname)=REPLACEME=g" -i /etc/hosts && hostname "$(echo $RANDOM | md5sum | cut -c 1-7 | tr a-z A-Z)" && sed "s=REPLACEME=$(hostname)=g" -i /etc/hosts && macchanger -e eth0 && dhclient

this string of commands will release your dhcp address, change your mac address, generate a new random hostname and then get a new dhcp lease.

Quick shortcut if you know the hostname and want to save yourself one step for looking up the IP address separately.

hostname -i

I've seen some versions of hostname that don't have the -i option, so this may not work everywhere. When available, it's a better alternative than using ifconfig and wasting eyeball muscle to search for the address, and it's definitely simpler than using awk/sed.

ssh -vN hostname 2>&1 | grep "remote software version"

I used this to confirm an upgrade to an SSH daemon was successful

newhostname=$(hostname | awk -F. '{print $1 "." $2}'); ipaddress=$(nslookup `hostname` | grep -i address | awk -F" " '{print $2}' | awk -F. '{print $3 "." $4}' | grep -v 64.142);PS1="[`id -un`.$newhostname.$ipaddress]"' (${PWD}): '; export PS1

changes the PS1 to something better than default.

cat .ssh/id_rsa.pub | ssh hostname 'cat >> .ssh/authorized_keys'

Functions: cat hostname ssh

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).
