System Administrator usually use SSH to remote his Linux servers. So he might need a SSH client to do that. If he use a Linux client, his Linux might already have SSH client installed. If he use Windows client, one of the most popular SSH client is Putty.
We have already seen in NST Linux, we can SSH to the server via browser. Now, you can change you Linux server to become like that using shellinabox application.

Hi, I tried this concept then also I got the error to log in as any user in the browser. By spending lot time then only I found that you missed this rule while editing in the configuration file. I gave the details below.
On CentOS Linux
# vi /etc/sysconfig/shellinaboxd
OPTS="--disable-ssl-menu -s /:LOGIN" #It wont allow to login in a browser
OPTS="--disable-ssl-menu -s /:SSH" #It will allow to login as ssh in a browser
is there any way to pre login with certain username. i mean i have embedded the shellinabox in custom webpage so now i want to show only password prompt not username..
