Configuration (sorry to have missed that): /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=peugeot.ip6 IPV6FORWARDING=no IPV6_AUTOCONF=no IPV6_ROUTER=no /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 ONBOOT=no IPADDR=10.0.1.1 NETMASK=255.255.255.0 NETWORK=10.0.1.0 BROADCAST=10.0.1.255 NAME=wlan IPV6INIT=yes IPV6ADDR=FEC0::1/64 FWIW, the problem is with some interactions with hotplug: if I do /sbin/ifup ethX it works fine, but though hotplug, it doesn't. Perhaps due to having no stdin/stdout? Hm, I'm having problems assigning static IPv6 address to eth0 as well... but this is a fixed NIC. The address just doesn't get configured to the interface. Config is basically the same like the original reporter has. Pls ignore last comment. The reason was that I edited /etc/sysconfig/network-scripts/ifcfg-eth0 to add the IPv6 stuff, but the ipup-ipv6 script uses only /etc/sysconfig/networking/profiles/default/ifcfg-eth0 (which exists on some of my machines... on others, there is only the /etc/sysconfig/network-scripts/ifcfg-eth0 one... hm.). Quoting from rhl-devel list..
========
[...]
--8<--
ipv6_exec_ifconfig() {
local options=$*
LC_ALL=C /sbin/ifconfig $options 2>&1
return $?
}
ipv6_exec_ifconfig $device inet6 add $address || return 3
--8<--
1) works if you remove "2>&1", or
2) works if you change the command to like:
"ipv6_exec_ifconfig $device inet6 add $address > /dev/null || return 3"
I.e. it seems as if "2>&1" does not work with hotplug's "unspecified"
stdout/stderr fd's.
So..
- Is there a bug in hotplug's handling of stdout/stderr ?
- Is there a bug in bash's handling of "2>&1" when 1 is implicitly /dev/null?
- Is there something I'm missing? :-)
==========
so, based on current understanding, we're working around this issue by avoiding
the use of "2>&1", but I fear this may only be a work-around at some other
problem. Thoughts?
My thoughts would be 'a) that's weird b) I haven't had time to look at it deeper yet'. When I looked at hotplug to see if there are any obvious issues there, I can across this Debian bug report of a possibly similar issue: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=145484 could be related. Patch added in 7.30-1. |
Description of problem: When I try to configure an 802.11b PCMCIA network card (Orinoco compatible) with an IPv6 site-local address, FEC0::1/64, the address is not assigned to the interface. After some experimentation, it turns out that the call to ifconfig to set the address (in /etc/sysconfig/network-scripts/network-functions-ipv6) fails with ifconfig giving returncode 1 and the networking scripts exiting on this error. When I execute the *exact* same ifconfig line by hand after this failure, everything works fine. Version-Release number of selected component (if applicable): 6.67-1 How reproducible: Every time on insertion of network card Steps to Reproduce: 1. Configure the network as described below, and add hermes.conf in /etc/pcmcia to add support for orinoco_cs.o 2. Restart PCMCIA subsystem and insert WLAN card Actual results: #ifconfig eth1 eth1 Link encap:Ethernet HWaddr 00:02:2D:5E:FA:BD inet addr:10.0.1.1 Bcast:10.0.1.255 Mask:255.255.255.0 inet6 addr: fe80::202:2dff:fe5e:fabd/10 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Expected results: #ifconfig eth1 eth1 Link encap:Ethernet HWaddr 00:02:2D:5E:FA:BD inet addr:10.0.1.1 Bcast:10.0.1.255 Mask:255.255.255.0 ----> inet6 addr: fec0::1/64 Scope:Site <---- inet6 addr: fe80::202:2dff:fe5e:fabd/10 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Additional info: Laptop configuration: Compaq Armada 1700, PII-350, 128MB eth0: 3Com 3CCE589ET 10 Mb/s ethernet card eth1: ARtem ComCard 1.0 (rebadged Orinoco card)
