I’m used with distributions that have networking commands like
netstat, ifconfig, etc in their default installation so, when I
started using ArchLinux on daily basis, I found that these commands
are missing.
In effect ArchLinux doesn’t have these commands on a base install but you can install them using:
pacman -S net-tools
I’m curious and so I immediatly thinked: the ArchLinux mantainers are
really smart so why they have choosen not to install net-tools by
default? Answer: they have alternative tools.
These alternative tools are ss and ip. This is an example:
$ ss -l | grep tcp
nl UNCONN 4352 0 tcpdiag:ss/27803 *
nl UNCONN 768 0 tcpdiag:kernel *
tcp UNCONN 0 0 *:ipproto-68 *:*
tcp UNCONN 0 0 10.5.7.203:ptp *:*
tcp UNCONN 0 0 127.0.0.1:ptp *:*
tcp UNCONN 0 0 *:ptp *:*
tcp UNCONN 0 0 *:ipproto-57859 *:*
tcp UNCONN 0 0 :::ipproto-23550 :::*
tcp UNCONN 0 0 fe80::a00:27ff:fefb:86d0:ptp :::*
tcp UNCONN 0 0 ::1:ptp :::*
tcp UNCONN 0 0 :::ptp :::*
tcp LISTEN 0 128 *:ssh *:*
tcp LISTEN 0 128 :::ssh :::*
and you can use ip like this:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 08:00:27:fb:86:d0 brd ff:ff:ff:ff:ff:ff
inet 10.5.7.203/17 brd 10.5.127.255 scope global enp0s3
valid_lft forever preferred_lft forever
inet6 fe80::a00:27ff:fefb:86d0/64 scope link
valid_lft forever preferred_lft forever
