Prosta rzecz, a nie wiedziałem. Jak sprawdzić jaki mam adres ip, czyli taki odpowiednik ipconfig z Windows:
ip addr show
[sybase@localhost log]$ ip addr show 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: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:15:5d:01:6e:04 brd ff:ff:ff:ff:ff:ff inet 192.168.1.104/24 brd 192.168.1.255 scope global dynamic eth0 valid_lft 78732sec preferred_lft 78732sec inet6 fe80::215:5dff:fe01:6e04/64 scope link valid_lft forever preferred_lft forever
