TOPIC: Loose IP settings every reboot
#11789
Loose IP settings every reboot 2 Years, 11 Months ago  
I support a remote clearOS 5.1 install. It is configured in gateway mode.

Every time this PC reboots, the config for ETH0 is lost (the WAN IP). It is supposed to be "external" with static IP information. When the system boots, it comes up "LAN" with static, but does not retain the IP or Gateway.

Therefore, everytime this PC reboots, I have to walk someone through reconfiguring ETH0. We have to change the role, and configure the IP and gateway. After confirming the change, system works fine until next reboot.

I've never had a problem with Clear (or Clark Connect) before, and I'm not sure where to start looking.

I see:
/etc/sysconfig/network
Code:
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME="changed.for.security"
NOZEROCONF=yes
GATEWAYDEV="eth0"


/etc/sysconfig/networking/
-- nothing under this directory or its subdirectories

/etc/sysconfig/network-scripts/ifcfg-eth0
Code:
DEVICE=eth0
TYPE="Ethernet"
ONBOOT="yes"
USERCTL="no"
HWADDR="00:40:05:00:00:00"
BOOTPROTO="static"
IPADDR="192.168.3.253"
NETMASK="255.255.255.0"
GATEWAY="192.168.3.254"


Thanks for your input!

There have been a number of reports of this sort of thing happening during the update process where kudzu gets a bit over-enthusiastic. You caold try setting the immutable bit on /etc/sysconfig/network-scripts/ifcfg-eth0 and perhaps also /etc/sysconfig/network e.g.:
Code:
chattr +i /etc/sysconfig/network-scripts/ifcfg-eth0

Remember to unset it if you want to change the file.

Thanks!

I flagged both files and crossed fingers during reboot. Came back up by itself and everything's perfect!

On every machine as a matter course I always do the following (Including Fedora and CentOS) :-
Code:

chattr +i /etc/sysconfig/network-scripts/ifcfg-eth*
chattr +i /etc/resolv.conf
chattr +i /etc/modprobe.conf

also make sure the MAC address is in every ifcfg-ethX file...
