Re: [SLUG] Network Errors
Australian PCAuthority had a fairly good article on how and why these sort of network errors cause problems. April 2000 issue. page 188. basically try manually setting the cards to half duplex first, 10mbs, etc. also some hubs set themselves (all their ports) to the speed and/or duplex of the *first* network card that connects. all the others have to conform to that. too bad if the second connecting card is switched to full duplex, 100mbs. it will have problems connecting etc. well this is what the article says anyway. -- _|_ | Thanks, iCafe PTY Limited Ben DonohueWeb Hosting Design [EMAIL PROTECTED]Small Business Office Networks Ph. 0011 61 2 9705 7520 http://www.icafe.com.au Mobile: 0417 018 600ACN 080 665 907 Freedom isn't doing what you want...

Re: [SLUG] Network Errors
I had a similar problem about a year ago at a client's site. I tried several cards. Acer PCI Realtek RTL8139 cards, generic ISA PCI NE2000 cards, none of them worked with a Netgear 100Mb Hub. The problem occured when people sent large attachments from their 100Mb card desktop, through the linux gateway. It does IP Masq. thru a modem dialup. It seems to flood the network card and bring down the network interface requiring a reboot. But then I tried a 3com515 ISA 10/100 card, and it was the only one that worked. Apparently even though the 3c515 card is 10/100 the ISA port doesn't go that fast, hence restricting the speed. Anyway, you can't buy those cards anymore, so like the old saying, "they don't make it like they use to" applies once more. :) You may be able to pick them up second hand though Regards, Adrian.

Re: [SLUG] Network Errors - Final
Hi all. Well the problem solved itself yesterday - the 10BaseT HUB burst into smoke and flame - good indication I had to get another HUB sadly ;-( The network problems have gone now I have a 100BaseT Switch (only $180 from North Rocks Computer Markets).

This is due (from what ive gathered from various lists) that my switch is just dropping packets and not telling, so the sender waits for a time out then sends again. I fixed this by locking down the 100mbps to 10hd. Which is bad considering the cash i paid for the intel inbuisness switch. I think smart switches might be better at 100 -- 10 mbps conversion if you were really bored and still didn't want to buy another 100M card, you could try messing around with the 2.2/2.4 routing stuff and throttling traffic destined for the 10M host down to 10Mbps - leaving the rest still running at 100Mbps.. -- - Gus -- SLUG - Sydney Linux Users Group Mailing List - http://www.slug.org.au To unsubscribe send email to [EMAIL PROTECTED] with unsubscribe in the text

[SLUG] Network Errors
Thanks DaZZa, Dean, Gus and others. I have tried using the setup disk to 10 Mb mode but without result. I assume purchasing a 100BaseT HUB would be the best solution - Yes ?

Kieran [EMAIL PROTECTED] Sorry, I won't stand by and have you bash Intel. My Intel InBusiness 4port Hub works sweetly, haven't had a problem with it and my 3com cards there's probably less for them to stuff up in a hub rather than a switch.

Seriously, 3Com and Intel cards are amongst _the_ most problematical I've worked with - and, believe me, I've been working with LAN gear a _long_ time. Okay so I like name brands :-) I don't.
