Description Gene Czarcinski 2000-04-12 21:48:38 UTC

I have a system with two interfaces: eth0 static def to internal 192.168
network and eth1 dhcp attached to a cablemodem.

With rhl 6.1 + maint and kernel 2.2.12-30, everything works.  eth0 is
brought up at boot time, and eth1 is started via a script with uses
/etc/sysconfig/network-scripts/ifup eth1

With rhl 6.2 (kernel 2.2.14-5.0), this does not work ... it 'fails'

I have found that if I DO NOT start either interface at boot time and then
manually start eth1 first and then eth0, it does work.

However, if I then shutdwon the interfaces and try restarting them, it
fails again.

This "may" be something with pump OR it may be something with the kernel.
I tried updating the kernel on my 6.1 system to 2.2.14-5.0 and interface
initialization failed (as best as I can remember, in the same way).

Comment 1 ard 2000-04-26 14:21:59 UTC

All pump problems regarding 2.2.14 may exhibit this behaviour:
When doing a DHCP_REQ with a source address that should have been 0.0.0.0, it
seems to use the source address of the interface that is already up.
And usually the dhcp-server cannot route back a reply to the (usually local)ip
number...
Thus:
It sends a DHCP request with source 192.168.0.1 and destination 255.255.255.255,
instead of source 0.0.0.0; 192.168.0.1 is the address of my other ethernet card.

Comment 2 Lars Enstedt 2000-10-17 18:25:22 UTC

I am seeing the same problem with the 2.2.16-3 kernel.

The machine has three ethernetcards (of the same type) with eth1 and eth2 is having
static black addresses (rfc 1918) and eth0 is configured for dhcp. When the machine
does a DHCP_REQ the source IP address of that packet is set to the eth1 static IP
address instead of 0.0.0.0. If I remove the IP configurations for eth1 and eth2 it works
fine and is sending the DHCP_REQ with the IP source address of 0.0.0.0.

I have tried this with the following versions of pump:
pump-0.7.8-1   from RedHat 6.2 (which I am running)
pump-0.8.3-2   from RedHat 7.0 (src.rpm compiled then installed)
pump-0.8.4-1   from RawHide 1.0 (src.rpm compiled then installed)

I hope to se a fix on this soon. 
Perhaps Erik Troan <ewt> can get his teeth into this?

Apologies for the unresponsiveness of the previous pump packager...

Please try the latest release, 6.2 is ancient.
