Re: Ethernet problems: old 3c509b card is having overrun and errors
It seems that at least switching to the other card doesn't seem to lead to overruns and errors. I'll have to run some transfers to be sure. Thanks lots for the help! Is there others here who know about software channel bonding in Linux? It would be an interesting thing to do. Calyth -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Re: Ethernet problems: old 3c509b card is having overrun and errors
Well I got a spare 3c509 that has not been used. I suppose I could try that card too. I got no spare cable, but if the spare card is also having problems, that would give me a good idea what's going on. Thanks all for the help!

Me too, I had two 3c509 ISA (out of the three I had) die in similar ways in the few last weeks.

While this seems a little fussy, it becomes important when talking about large quantities. The difference between a Kilobyte and a Kibibyte is 24 bytes (2^10 10^3,) an amount very few people are going to notice or care about.

It has to be something bytes, but what?) Don't know about the actual problem, but MiB stands for MibiBytes, where Mibi is the proper way to say 'powers of 1024' (Mi == 1024*1024), in contrast to the M of Mega, which is a power of 1000 (M == 1000*1000). Normally an oridnary Mega is used to denote 1024^2, but since we do not want to contradict the Systeme Internationale, Mibi is introduced (along with kiB, kibibytes). Cheers, Sebastiaan -- NT is the OS of the future. The main engine is the 16-bit Subsystem (also called MS-DOS Subsystem). Above that, there is the windoze 95/98 16-bit Subsystem. Anyone can see that 16+16=32, so windoze NT is a *real* 32-bit system. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
RE: Ethernet problems: old 3c509b card is having overrun and errors
Sounds more likely to be a hardware problem. Check cables with a cable tester and try changing the network card. These problems aren't normal and a 486/32MB ram configured as a samba server for a small no of users should be ok. To answer the question on ethernet card bonding, it's possible to get 4-port network cards that support bonding. An example of this is the D-link 570TX. I've used this before as 4 separate nics, but not in the bonding mode.
