Thread: configuring IPv4 with fixed ip


hi,

there experiencing similar problems me? our router pretty old , capable of giving fixed ip , there no support ipv6. via gnome networkmanager try set manual ip 192.168.1.123 , netmask 255.255.255.0 , default gw @ 192.168.1.1 . however, not work.

if open terminal , type:

code:
sudo ifconfig eth0 inet 192.168.1.123 sudo route add default gw 192.168.1.1
then valid connection internet.
ifconfig self returns:

code:
myname@mycomp:~$ ifconfig eth0 eth0      link encap:ethernet  hwaddr 00:0f:1f:74:e1:be             inet addr:192.168.1.123  bcast:192.168.1.255  mask:255.255.255.0           inet6 addr: fe80::20f:1fff:fe74:e1be/64 scope:link           broadcast running multicast  mtu:1500  metric:1           rx packets:8050 errors:0 dropped:0 overruns:0 frame:0           tx packets:7522 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:100            rx bytes:8122461 (8.1 mb)  tx bytes:1243808 (1.2 mb)
the difference between ifconfig before , after
code:
sudo ifconfig eth0 inet 192.168.1.123 sudo route add default gw 192.168.1.1
commando after cli commando's inet line added ifconfig output.

ffor me seems gnome network manager doesn't save information gently ask to.
hope can me.

can fix cli commands, know whats going on.

kind regards,

maarten

look network-manager applet/icon on desktop, right-click on , select 'edit connections' or select 'system/preferences/network connections'.
typically connection should show 'auto eth0'. if doesn't, add it. make sure in ipv4 tab, have selected 'manual' 'method'.
fill in data connection necessary.

regards,

marc
