alternately you can run sysinstall as root and change it to static there

 

by: dpiniellaPosted on 2005-11-28 at 17:56:38ID: 15377083

see also http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/config-network-setup.html section of the handbook

if you want to set it statically and persistently (ie, just running ifconfig will lose the IP on reboot and switch back to dhcp) then you have to edit /etc/rc.boot and add lines for your network cards as in the handbook:
ifconfig_dc0="inet 192.168.1.3 netmask 255.255.255.0"
ifconfig_dc1="inet 10.0.0.1 netmask 255.255.255.0 media 10baseT/UTP"

(replace dc0 or dc1 with whatever your NIC's name is and set the right address after the 'inet' part)

 

by: gheistPosted on 2005-11-29 at 11:25:40ID: 15382684

and add to /etc/rc.conf

defaultroeter="10.0.0.254"

Or use sysinstall and choose configure while you are not familiar with vi or installing editors/nano

defaultrouter="10.0.0.254"


 

by: dpiniellaPosted on 2005-11-29 at 12:28:28ID: 15383135

whoa! typo on my last post, yes -- it's /etc/rc.conf that you need to edit. It probably already has an entry for your current NIC with the option DHCP; you just need to change that to what you want statically assigned, as in the handbook link above.

Hi dpiniella,

Thanks for your help.  I edited rc.conf as below and rebooted the server after plugging the cable into a static port.  After rebooting I could not ping the IP from another machine.  What should I try next given the info below?


# -- sysinstall generated deltas -- # Mon Nov 21 03:16:40 2005
# Created: Mon Nov 21 03:16:40 2005
# Enable network daemons for user convenience.
# Please make all changes to this file, not to /etc/defaults/rc.conf.
# This file now contains just the overrides from /etc/defaults/rc.conf.
hostname="ope-dev.domain.com"
#ifconfig_fxp0="DHCP"
ifconfig_fxp0="inet 175.17.110.51 netmask 255.255.255.0"
defaultrouter="10.0.0.254"
linux_enable="YES"
sshd_enable="YES"
usbd_enable="YES"
# -- sysinstall generated deltas -- # Mon Nov 28 13:19:47 2005
sendmail_enable="YES"


This is what I got from an ifconfig from the server's console after reboot

fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=8<VLAN_MTU>
        inet6 fe80::202:a5ff:fec2:b5d3%fxp0 prefixlen 64 scopeid 0x1
        inet 175.17.110.51 netmask 0xffffff00 broadcast 175.17.110.255
        ether 00:02:a5:c2:b5:d3
        media: Ethernet autoselect (100baseTX <full-duplex>)

is 10.0.0.254 what your default gateway should be? since you're using 175.17.110/24 network, i doubt it.
if not, change it to what it should be and reboot.
