Description Erik Heckers 2008-05-27 16:53:06 UTC
Description of problem: Default gateway not properly set after network installation After installing Fedora 9 my /etc/sysconfig/network looks like this: NETWORKING=yes HOSTNAME=__myhost__ GATEWAY=__mygw__ IPV6_DEFAULTGW= But the (ipv4) default gateway is not set, route command lists: # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface __net__ * 255.255.255.0 U 0 0 0 eth0 # As soon as I remove the line "IPV6_DEFAULTGW=" and restart networking with "/etc/init.d/network restart" everything is okay. # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface __net__ * 255.255.255.0 U 0 0 0 eth0 default __mygw__ 0.0.0.0 UG 0 0 0 eth0 I tried installing using the "noipv6" option, but still got that "IPV6_DEFAULTGW=" line. Version-Release number of selected component (if applicable): As provided by Fedora 9 images How reproducible: Always Steps to Reproduce: 1. Install Fedora 9 over network (with static ip in ks.cfg) 2. Check routing with "route" - default route missing. 3. Actual results: /etc/sysconfig/network looks okay, but as long as the line "IPV6_DEFAULTGW=" is in there no default route is set when restarting network with "/etc/init.d/network restart". Expected results: Default route using the gateway specified in /etc/sysconfig/network with "GATEWAY=gw" The "IPV6_DEFAULTGW" is something new, I have never seen it with installation of RHEL 3,4, or 5. Additional info: In ks.cfg I have network --device eth0 --bootproto static --ip __myip__ --netmask 255.255.255.0 --gateway __mygw__ --hostname __myhost__ Workaround: Remove line "IPV6_DEFAULTGW=" from /etc/sysconfig/network in %post section of ks.cfg. Bye Erik

I can confirm most of this behaviour when installing from DVD in GUI mode, except the workaround for me is quite different. I configured IPV4 manually and when I boot up the newly installed system, there is no default route, according to "netstat -rn". Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.16.72.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 However, unlike in Erik's case, neither commenting out the IPV6_DEFAULTGW line in /etc/sysconfig/network with a "#" or deleting the line entirely solves the problem. For me, I had to add "GATEWAY=172.16.72.254" to my /etc/sysconfig/network-scripts/ifcfg-eth0 script to get the default route to appear after a reboot.

I've just done a yum update, and now the original /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-eth0 as created during the install work fine.
