SSH connections through proxies

SSH connections through proxies

Sometimes, it is very annoying to connect into a server that is bind a firewalls. You need to connect that is reachable outside first and then ssh into the server.

Here is a little tip I found;
http://sshmenu.sourceforge.net/articles/transparent-mulithop.html

The explanation in above page is extremely helpful, so you got to read it.
For the short summary for a head-first person like me,
you can set up a ssh config file, $HOME/.ssh/config, like the following example.

#### Example .ssh/config file #####

Host *
        ForwardX11 yes
        Compression yes
        ServerAliveInterval     120
        ServerAliveCountMax     3

Host proxyserver
        Hostname proxy.myworkplace.edu

Host myworkstation
        ProxyCommand ssh -q proxyserver p nc -q0 Hera 22

Without this setting, I ran "ssh proxyserver" first and then "ssh myworkstation" from the proxyserver.
But, this config file helps me to log into my workstation with single "ssh myworkstation" at home!!

HP Laptop Beat Audio Sound Problem in Linux

I recently purchased a HP laptop. It works well and much better than what I anticipated. Except one, well, two problems in Ubuntu.

One problem is the sound is too soft in Ubuntu, and the other problem is the fingerprint security system.

After some googling, I figured that the sound problem can be fixed,

Basically, manually overide non-detected internal speakers. HP laptop has two additional speakers, how cool is that!!

However, I could not find the suitable driver for the fingerprint security system.

:(

At least I am enjoying better sound!!

Good job HP, and hopefully HP cares more about linux, too.

My new year's resolution.

Do not judge and don't be afraid to be judged!
