^ That means - the IP address of the device or Network in question starts with 144.  Did that help? ;-) BTW, how is this a "Linux" issue? ~@~

Sajha bro: one more question: How do i disable the ports and enable the ports in Linux?

That means, the IP Belongs to Class B .  And to disable ports in Linux, either you turn the service associated with that port off or you can use firewall to block the port.

/etc/init.d/iptables stop nc -l -p <port#> This will let you open virtually any port, between 1 - 65535 --- NO, don't do what I just suggested. It will work, but people won't like it. Here's what you can do: -Install the service you're looking to run on your linux system -Start that service. Generally it is "service start <servicename>", "/etc/init.d/<servicename> start", etc... -Allow port through iptables, if enabled ~@~

I thought there was a way from netstat command. Please correct me from wrong! Also, Nishant: Class B means: Start address: 128.0.0.0 End address: 191.255.255.254 Ke yo true ho? Malai kaam ma sodho ke yo kura. Kunai link chha other than wiki to learn networking and Linux in detail. Chha bhane please post those links so i may go through them. Thank you for the information!

@newguyintown   www.linuxhomenetworking.com is a good site.  And it's better to learn specific items researching over the internet rather than a single site for everything. These are the basics you would want to learn : VI Editor MySQL Configuration. (Database backup, restore, creation, privilege handling )  User / Group and Permissions. Disk Partitioning Apache Installation, configuration with various modules (mod_ssl, mod_python) , SSL Configuration, Generating Self Signed Certificates and so forth. Basic Linux Hardening. Password less SSH Setup IPtables basic configuration. Shell Scripting ( Basic) I think these are the basics for a LAMP Admin, however this might not be enough. I am planning to start an online class for linux starting september, PM me if interested . I do have 10+ years of background in IT, 10+ in Linux and 6+ in Security. I also maintain a blog for various linux tutorials :  http://www.amitnepal.com Thanks
