 Posted: Tue Nov 18, 2003 7:12 am Post subject: eth working, but no info |
 |
|
I've got two nic's in my computer, both of them works flawless (using eth1 to grab internet and routing over eth0). However, everytime I try to use one of those "bandwidth-programs" (bwbar/mrtg/bwmon/etc) on my eth0, it shows up and tells me what i want to know. That however is not the case for eth1, surely it works, but it seems that it wont publish any of it's information to for example, /proc/net/dev or /proc/net/dev_mcast (only eth0 and my there).
A strange output from dmesg:
| Quote: |
war@gentoo / $ dmesg |grep eth
eth0: SMC1211TX EZCard 10/100 (RealTek RTL8139) at 0xf080fc00, 00:e0:29:6b:cc:fa, IRQ 11
eth0: Identified 8139 chip type 'RTL-8139B'
eth0: Setting 100mbps full-duplex based on auto-negotiated partner ability 45e1.
|
Any clues?

The output is:
| Quote: |

(the XXX is just a hidden value.)
Is it the NOTRAILERS that has something to do with this?

What's the driver/NIC? - the only thing I can think of is that the driver isn't creating the entries in /proc (although I'm not sure that the driver is responsible for this - it might be a level further up).
I use tulup,realtek and 3c509 cards with no problems (just checked them all to see if thay had proc entries, they did. |

hmm. I thought I'd replied to this... oh well.
Use 'lsmod' it will list all currently loaded modules (assuming the driver is built as a module, not compiled in). Also is eth1 a realtek too or is it a different card? |

The eth1 device is using a 3c59x driver, i dont know what model exactly but i assume that this is what you need to know, then, as a second question, does it affect if net network card got the NOTRAILERS option set?
Thank you, i'm really glad someone could help me with this kind of problem!

I don't think the NOTRAILERS matters (although I can't seem to find out what it means) as I have on my 3c509
| Code: |
eth0 Link encap:Ethernet HWaddr 00:20:AF:9B:C6:9B
inet addr:xxx.xxx.xxx.xxx Bcast:xxx.xxx.xxx.255 Mask:255.255.255.0

collisions:379 txqueuelen:100

I would say it looks like a problem with the driver/card combination.
And it has OK /proc entries.
Just found a link http://linuxquestions.org/questions/archive/3/2003/02/3/45475 that explains what notrailers means. |

What if you use bwmon on your eth1 card?

I can't test that - the two NICs are in my firewall which boots from CD, so software installation isn't an option (which is probably a good thing for a firewall)
However it does have:
| Code: |
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
lo: 12564 99 0 0 0 0 0 0 12564 99 0 0 0 0 0 0
dummy0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
eth0:1296396059 4396076 0 0 0 0 0 0 221949151 1490260 0 0 0 414 0 0
eth1:261521641 1787805 0 0 0 0 0 0 1109404278 1653625 0 0 0 0 0 0

in it's /proc/net/dev so I imagine it would work.
eth0 is a 3com3c509 (an old ISA one)
eth1 is some kind of DEC tulip based NIC possibly a Linksys.
Kernel is 2.4.22 vannilla |

Well, thanks anyway, i'll be inserting another nic instead, since recompiling the kernel didn't work. I've really appriciated your help, then again. Thank you!
