Forgive me if I'm just a frickin' moron, however this issue only came apparent to me after the install of FC1. I'll give you my lay out first. 1. ADSL connection using pppoe. The adsl connection works fine. 2. Two ethernet cards in the machine. The first card (eth0) is a pci drop in card that runs on the tulip driver. Some sort of LNETX or some such card. It's always worked previous and does work (somewhat I believe) now. The other is a Via-Rhine card integrated onto the Asus mobo(a7v8x-x) it's known as eth1. 3. ifconfig shows the cards as described above. 4. dmesg seems to not show the above described situation. Rather it states the following: via-rhine.c:v1.10-LK1.1.19-2.5 July-12-2003 Written by Donald Becker http://www.scyld.com/network/via-rhine.html eth0: VIA VT6102 Rhine-II at 0xed800000, 00:0c:6e:28:5b:11, IRQ 23. eth0: MII PHY found at address 1, status 0x786d advertising 01e1 Link 41e1. PPP generic driver version 2.4.2 NET: Registered protocol family 24 Linux Tulip driver version 1.1.13 (May 11, 2002) tulip0: MII transceiver #1 config 3100 status 7829 advertising 01e1. eth1: Lite-On 82c168 PNIC rev 32 at 0xf882f000, 00:C0:F0:3D:E8:14, IRQ 19. 5. I run kernel 2.6.0test11 currently. The kernel I use makes no difference to the problem I have at hand. PROBLEM Regardless of what dmesg says about my ethernet cards, ifconfig identifies the tulip card as eth0 and the via-rhine card as eth1. Irregardless they function (somewhat). I can get LAN boxes (winxp and FC1) out to the net. Here is where I am stumped. Ftp/dcc no longer function correctly for -any- boxes on the nework. My LAN boxes stall out on downloads of any sort after up to or in excess of 1.3 or so megs. The FC1 box that provides the routing (where the two ethernet cards in question are installed) can ftp and all that good stuff. WHAT I HAVE DONE Thus far, I have tried toying with iptables. I figured connection tracking was broken (as in I didn't load the modules). I did this in 2.4 series for FC1 and in 2.6, the downloading problem still exists. I recompiled 2.6 to have all of the necessary iptables/NAT stuff compiled in. ipv6 stuff is modular. Although the ipv6 modules are currently loaded, this was also true previous to the FC1 install and I had no problem with downloads/uploads. In a fit of just plain "I have no idea what to do now I've done all the iptables reconfiguring I can think of and it still doesn't work" I ran ethtool: [root@ghostlike log]# ethtool eth0 Settings for eth0: No data available I then ran it for eth1: [root@ghostlike log]# ethtool eth1 Settings for eth1: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 1 Transceiver: internal Auto-negotiation: on Current message level: 0x00000001 (1) Link detected: yes I believe this is what is causing my problem. eth0 is not correctly being identified or whatever. I'm not smart enough to figure this one out on my own. I'm self taught everything and finally I have to ask for some help. Have I given enough information? Perhaps I can show you what mii-tool states for the two cards. [root@ghostlike log]# mii-tool eth0 eth0: no autonegotiation, 100baseTx-FD, link ok And for eth1: [root@ghostlike log]# mii-tool eth1 eth1: negotiated 100baseTx-FD, link ok REHASH Is my problem hardware related, as to why my downloads/uploads die out on the LAN boxes with tryign to either update one of the boxes via yum or even download a kernel tarball from kernel.org? Or is this a configuration error? Here are the modules loaded for my kernel at present, in case this is of some importance to anyone: [root@ghostlike log]# lsmod Module Size Used by ide_cd 37252 0 cdrom 32672 1 ide_cd ipv6 231424 21 autofs 14272 0 n_hdlc 8836 1 ppp_synctty 7552 1 ppp_async 9408 0 thermal 11280 0 processor 11556 1 thermal fan 2892 0 button 4568 0 battery 7948 0 asus_acpi 8728 0 ac 3724 0 I would like to point out that all of the netfilter/iptable/NAT stuff is compiled into the kernel. Sorry for such a long mail. I can be told to shut up at any point lol TIA Alex White -- We don't have a great war in our generation, or a great depression, but we do, we have a great war of the spirit.
