ifconfig: command not found

I ssh into a remote machine with root which is installed with Fedora 18. I typed in

ifconfig

but I got

ifconfig: command not found

and also

 [root@kitch proxy]# /sbin/ifconfig -bash: /sbin/ifconfig: No such file or directory [root@kitch proxy]# sudo yum provides ifconfig fedora/filelists_db | 25 MB 00:00:04 updates/filelists_db | 12 MB 00:00:02 net-tools-2.0-0.2.20121106git.fc18.x86_64 : Basic networking tools Repo : fedora Matched from: Filename : /sbin/ifconfig

then I typed in ip link show

 [root@kitch proxy]# ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT qlen 1000 link/ether 00:1a:a0:23:86:6c brd ff:ff:ff:ff:ff:ff

and ip addr show

 t@kitch proxy]# ip addr show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 00:1a:a0:23:86:6c brd ff:ff:ff:ff:ff:ff inet 138.96.116.9/21 brd 138.96.119.255 scope global em1 inet6 fe80::21a:a0ff:fe23:866c/64 scope link valid_lft forever preferred_lft forever

and

 [root@kitch proxy]# /sbin/iptables iptables v1.4.16.2: no command specified Try `iptables -h' or 'iptables --help' for more information.

there is no eth0 and the results are strange to me. Can anyone explain a bit?

Both Fedora and RedHat identify NICs that are embedded on the motherboard by emN instead of ethN.

EDIT: If you want to prevent uvdev from renaming eth0 to em1 check this:

ifconfig on Red Hat-esque boxes often lives in /sbin, which often isn't in the default path; try /sbin/ifconfig and see what you get.

The manual page for ip is a good place to start finding out about its options, behavior, output, &c.

By default, ifconfig wont be there in RHEL.

sudo yum install net-tools

will instal ifconfig in /usr/sbin/ifconfig
