Tell HN: Practicing GNU/Linux commands

We (http://www.webminal.org/terminal/proxy/index/) are running a shared server environment for practicing GNU/Linux commands. It uses shellinabox terminal emulator. If you want to try, you can use any of the following username/passwd for login: wmuser1/mg55f wmuser2/g52km wmuser3/h85gf wmuser4/ra82m wmuser5/ov11f Use recent version of Firefox or Chrome, some users reported few (chrome) issues, try your luck! If you have feedback or find any security holes, please let me know! Note: This environment is for basic command-line practicing, we applied resource limits to prevent any abuse.
