Re: [PLUG] Question About Module Loading
Did you remake the initrd image? Depending on your settings it's possible the module is getting loaded by initrd before the normal module loading takes place. This is more common with scsi modules but I've had it happen with ethernet cards on some distros that support running with root of an NFS server. On Thursday 24 December 2009 09:30:05 pm Mark Phillips wrote: I just installed Debian stable (2.6-amd64 kernel) on a machine. I had to remove the kernel module for the Ethernet card and add a different one. The new module compiled etc and works. However, I had a problem preventing the old module from loading. There was no modprobe.conf file, but instead a directory modprobe.d with a lot of files in it. However, I could not find the expected alias line with the bad module's name. I finally googled a solution, and I am curious if this is the new way to disabling a kernel module: I created a file in /etc/modprobe.d/ called 00local. That file has one line: install r8169 /bin/true. This prevented the module r8169 from being loaded. I grepped all of /etc/ looking for r8169 and could not find where it was being loaded. I am so confused G'night and Happy Holidays to everyone!

Is something obviously wrong in my dhcp config file or am I looking at a problem with the switch? DHCP worked when I was using a 10BaseT hub which makes me wonder if the line can't support 100baseTX. It could be a problem with autoconfiguring the speed, and duplex of the connection. I've had two switches decide on different modes, and thus get a broken network. When one side is a dumb 10 megabit hub it doesn't try to negotiate, so you never have to worry about that problem. If you can force it into different modes try that. I forced the server to half duplex using ethtool, but I can't force the client to go to half duplex. Put the 10Mbit dumb hub back in, dhcp worked like a charm and the machine network booted no problem. I wonder if being a switch it was blocking the dhcp replies? I should in theory be able to pull the hub and replace it with a crossover coupler. I'm starting to think that the switch I was trying to use is bad or maybe I need a 100 megabit per second hub instead. Thing is, I use another DSS5+ switch with a linksys wireless WAP11 plugged into it that configures via dhcp no problem. I'm not sure what the issue is here. Just to double check, 190' is within the range limitations for 100BaseTX, right? ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug Yes, up to 300' in the accepted range. I don't think Daniel nor was I referring to the client/server but the switch itself. Most switches are auto sensing the link speed and do just fine, without knowing what kind of switch it is and what capabilities it has, it's hard to say what count be causing the problem. Could be VLAN's, could be auto sense not working, could be an ACL .. but without knowing what hardware it is, hard to say.

Spanning Tree port configuration is another. With regular spanning tree (8021.d), the switch port could be in blocking mode while the spanning tree is being mapped out and therefore any DHCP traffic will not pass thru the port. As best practice we always configured the switch ports with rapid spanning tree (802.1w), so that spanning tree convergence happened faster and didn't impact dhcp requests. ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

I am running DHCP 3 server on CentOS 5.3 listening on an actual Netgear FA311 network card with an actual Cat5e UTP cable running 100' into the attic where at this point I go to a 10BaseT hub and from there I continue on with a Cat5 STP cable outside, underground, back above ground, and into another building where I terminate at another FA311 network card in my diskless server. I tried to replace the Dlink hub with a Netgear DSS5+ 5 port switch. I guess my switch is faulty. It seems unlikely that the cables themselves didn't handle 100BaseTX transmission okay.

It is possible that the switch is faulty, however my experience with auto-negotiation is that each vendor (hub, switch, network card) interpret and implement the N-WAY standards differently. Does the D-Link hub support auto-negotiation? That could explain why the hub works and the switch doesn't. If the hub doesn't support auto-neg then both ends of the connection will fall back to 10mbps half-dup and all is well. If auto-negotiation isn't configured the same on both the switch port and NIC then there will be duplex mismatch errors. A telltale sign of duplex mismatch is Ethernet errors such as Frame Check Sequence errors, late collisions, and runts. You can use the 'ethtool' command to look at Ethernet interface error counters. ___ PLUG mailing list PLUG@lists.pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

Just to be safe, mount /dev and /proc: mount -t proc none proc mount -o bind /dev dev 5. chroot into your root filesystem: chroot . /bin/bash source /etc/profile 6. Run the command grub to enter the interactive grub shell. 7. Once in the grub shell, type the following grub commands: root (hd0,0) setup (hd0) quit 8. Type exit to exit the chroot. 9. Unmount all mount points you have previously mounted: umount boot dev proc cd .. umount sda3 10. Reboot. Take the CD out. Enjoy!

[PLUG] A Subversion Question

Re: [PLUG] Troubleshooting DHCP...
On a hunch after verifying that it still works when I use a 10Mbit hub, I replaced the hub with a crossover coupler. That is, I used something that is almost equivalent to a 100Mbit hub with 2 ports. It isn't working where I'm seeing the same symptoms. What could be making this work at 10Mbit but not at 100Mbit? The first line in the first building is 100' of Cat5e UTP cable, the second line is 90' of at least Cat5 STP cable. I'll have to check the lights on both ends. It just seems odd, I have a Netgear FA311 nic on both ends so they should be able to talk to each other. I have a new Netgear switch, but I don't want to open it unless I can't get this working. I wish I had some way of verifying that the line can operate at 100 Mbps.
