UNIX network configuration commands
Unfortunately syntax and options are not highly standardized
between OSes; consult your documentation for details on options
- ifconfig: configure network interface parameters
- Allows setting the IP address and netmask associated with an
interface and whether the interface is up (usable) or down
(disabled)
- route: modify routing table
- Can be used to add or remove route table entries, or show
routing table
- netstat: network status information
- Can be used to show active TCP connections, TCP and UDP server
sockets, UNIX-domain socket status, and routing
Semi-standard commands:
- ifconfig -a
- show all available network interfaces and
their status
- ifconfig interface
- show only information for a specified interface name
- netstat -r or route (no arguments)
- Show routing table status
- netstat -rn or route -n
- show status, but don't try to look up symbolic names
- netstat -a
- Show network connections including server sockets
- netstat -an
- Same, but don't look up symbolic names
