System: Linux 2.0.36 RedHat 5.2
Description:
When starting up the system lo device is not configured.
I receive the following messages:
ipcalc: ip address expected
ipcalc: ip address expected
ipcalc: ip address expected
netmask: unknown interface
netmask: Host name lookup failure
I updated /etc/sysconfig/network-scripts/ifup to display variable
contents.
This is what I got when configuring lo device:
Enabling IPv4 packet forwarding.
CONFIG is ifcfg-lo
SourceConfig CONFIG=ifcfg-lo
DEVICE=
OTHERSCRIPT=/etc/sysconfig/network-scripts/ifup- ifcfg-lo
DEVICETYPE=
REALDEVICE=
BOOTPROTO=none ISALIAS=no
IPSETUP=no BROADCAST= NETWORK=
IPADDR= NETMASK=
ipcalc: ip address expected
ipcalc: ip address expected
ipcalc: ip address expected
netmask: unknown interface.
netmask: Host name lookup failure
SourceConfig CONFIG=ifcfg-lo
usage: /etc/sysconfig/network-scripts/ifup-routes <net-device>
usage: /etc/sysconfig/network-scripts/ifup-aliases <net-device>
/etc/sysconfig/network-scripts/ifup-post: [: too many arguments
This is what I got when configuring eth0 device:
CONFIG is eth0
SourceConfig CONFIG=ifcfg-eth0
DEVICE=eth0
OTHERSCRIPT=/etc/sysconfig/network-scripts/ifup-eth ifcfg-eth0 boot
DEVICETYPE=eth
REALDEVICE=eth0
BOOTPROTO=none ISALIAS=no
IPSETUP=no BROADCAST=192.168.1.255 NETWORK=192.168.1.0
IPADDR=192.168.1.2 NETMASK=255.255.255.0
SourceConfig CONFIG=ifcfg-eth0
Can someone tell me how lo device can be configured without having
DEVICE set correctly ? Forcing DEVICE=lo do not solve the problem.
My feeling is that I did a mistake when configuring IP. I have a
backup I can use to come back to a stable situation. But knowing
mistakes is better than restoring tapes.
By the way: I have a 3 LAN level configured with an Internet Firewall
(1 firewall, 3 routers, 3 levels)
Is someone interested by the network routers configuration?
Thanks boys !
