What are some cool Unix/Linux commands?

Ifconfig netstat nc - NetCat. A very powerful tool for testing connectivity iftop - kind of like top, but for network connections traceroute ping telnet - not used in the normal way, but instead as a way to see if a port is open on a particular system "telnet hostname.foo.comm 53" tcpdump wireshark lsof - useful to see which process has a socket open (netstat -p will do that as well). ip - great tool for working with networking on a linux box nmap - nice tool for seeing what's out on the network. It's also a great way to upset the network security team if you're not one of them. scp - swiss army knife of connectivity. You can tunnel TCP connections with it, you can forward X sessions, you can even tar from machine to machine with an SSH tunnel.

Add Page Numbers to PDF: All You Need to Know

A nice utility to show the active protocols, and a nice tool for finding a particular port (you can type in port) Net dump The best looking tool in my opinion. Use it to see what's going on the network. Nmap — a port scanner It'll show you what services are running on a machine on port 80, you can scan a whole local IP range by specifying the addresses with net map. This can be a handy tool to see what's running on your host machine as opposed to your own machines. Wireshark — a great packet capture program to be used for debugging Wireshark can be used similarly to map. What I use: Ipconfig — I'm a stickler when it comes to getting that firs tip of my machine right. If you're running Fedora on your workstation then take a look at this guide: sudo DNF install config If you're running Ubuntu,.
