What's your /etc/sysconfig/network-scripts/ifcfg-eth0 look like? /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes TYPE=Ethernet What's your /etc/hosts look like? /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost What does /etc/sysconfig/network look like? /etc/sysconfig/network NETWORKING=yes HOSTNAME=localhost.localdomain In /sbin/dhclient-script (line #184)
if [ -n "$new_host_name" ] && need_hostname; then
hostname $new_host_name
fi
I found the call "hostname $new_host_name" corrupting
the hostname after calling the function "need_hostname" in
/etc/sysconfig/network-scripts/network-functions (line #193):
need_hostname ()
{
CHECK_HOSTNAME=`hostname`
if [ "$CHECK_HOSTNAME" = "(none)" -o \
"$CHECK_HOSTNAME" = "localhost" -o \
"$CHECK_HOSTNAME" = "localhost.localdomain" ]; then
return 0
else
return 1
fi
}
Here is the output in /var/log/messages with the option set -x
in /sbin/dhclient-script:
+ need_hostname
++ hostname
+ CHECK_HOSTNAME=localhost.localdomain
+ '[' localhost.localdomain = '(none)' -o localhost.localdomain =
localhost -o localhost.localdomain = localhost.localdomain ']'
+ return 0
+ hostname x1-6-00-10-a4-7d-cd-b3
What's your /etc/resolv.conf look like? more /etc/resolv.conf ; generated by /sbin/dhclient-script search comcast.net nameserver 204.127.199.8 nameserver 63.240.76.198 Presumably, 'host x1-6-00-10-a4-7d-cd-b3.comcast.net' does not return your IP address? What happens if you set the hostname to something other than localhost.localdomain in /etc/sysconfig/network, and add that to the end of the "127.0.0.1 ..." line in /etc/hosts? # host x1-6-00-10-a4-7d-cd-b3.comcast.net
Host x1-6-00-10-a4-7d-cd-b3.comcast.net not found: 3(NXDOMAIN)
00:10:a4:7d:cd:b3 is my MAC address
# more /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=linux
127.0.0.1
# /etc/init.d/network restart
/etc/init.d/network: line 3: 127.0.0.1: command not found
/etc/init.d/network: line 3: 127.0.0.1: command not found

Restored /etc/sysconfig/network and
# /etc/init.d/network restart
failed again.
The following commands started eth0 again:
# hostname localhost.localdomain
# cardctl eject
# cardctl insert
I missed the dots in /etc/sysconfig/network NETWORKING=yes HOSTNAME=linux 127.0.0.1 ... # /etc/init.d/network restart /etc/init.d/network: line 3: 127.0.0.1: command not found /etc/init.d/network: line 3: 127.0.0.1: command not found Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] /etc/init.d/network: line 3: 127.0.0.1: command not found Setting network parameters: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ] eth0 is up! Eek, sorry, i wasn't clear. In this case, you want: /etc/sysconfig/network to be: NETWORKING=yes HOSTNAME=linux and /etc/hosts to be: # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost linux This should alleviate the delay and the gnome warning. /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=linux
/etc/hosts
127.0.0.1 localhost.localdomain localhost linux
# /etc/init.d/network restart
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Setting network parameters: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: [FAILED]
So, after this, just 'ifup eth0' fails as well? /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=linux
/etc/hosts
127.0.0.1 localhost.localdomain localhost linux
First test:
# hostname linux
# ifup eth0
Determining IP information for eth0... done.
# hostname
linux
# ping yahoo.com <-- ok
# mozilla <-- hangs and times out
# hostname localhost.localdomain
# ping yahoo.com <-- ok
# mozilla <-- ok
Second test:
# hostname localhost.localdomain
# ifup eth0
Determining IP information for eth0... done.
# hostname
x1-6-00-10-a4-7d-cd-b3
# ping yahoo.com <-- ok
# mozilla <-- hangs and times out
# hostname localhost.localdomain
# ping yahoo.com <-- ok
# mozilla <-- ok
Hm, your best bet is probably to just hardcode need_hostname to return '1', and remove the HOSTNAME=linux hack. In /sbin/dhclient-script I hardcoded need_hostname to return '1'.
This solved the slow Start up and Log in process, however eth0 is
still down and Start service eth0 is reporting the error message:
Bringing up interface eth0: xircom_cb device eth0 does not seem to be
present, delaying initialization. [FAILED]
I was looking at the trace from /sbin/dhclient-script again, to find
where new_host_name is set to "x1-6-00-10-a4-7d-cd-b3", however it
looks like new_host_name is a uninitialized variable pointing to an
arbitrary string "x1-6-00-10-a4-7d-cd-b3".
In /sbin/dhclient-script:
if [ -n "$new_host_name" ] && need_hostname; then
hostname $new_host_name
fi
+ '[' -n x1-6-00-10-a4-7d-cd-b3 ']'
+ need_hostname
++ hostname
+ CHECK_HOSTNAME=localhost.localdomain
+ '[' localhost.localdomain = '(none)' -o localhost.localdomain =
localhost -o localhost.localdomain = localhost.localdomain ']'
+ return 0
+ hostname x1-6-00-10-a4-7d-cd-b3
The x1-.... is being returned by your ISP/cable modem. So, you need to run 'cardctl eject ; cardctl insert' for it to see the card? Yes 'cardctl eject ; cardctl insert' is needed as workaround. OK, so there are two problems here. 1) The hostname you're getting via DHCP is invalid; this is worked around by the editing of the need_hostname function. 2) Your card requires 'cardctl eject ; cardctl insert' to function, that's a kernel or PCMCIA bug. Assigning there. still a problem with fc3 ? fc1 - eol |

Log in for any user takes approximately 5.5 minutes, or until the Xircom PCMCIA Ethernet card is removed. After Log in, the Xircom PCMCIA Ethernet card needs to be removed and hostname set to localhost.localdomain for system to function properly.
