2 interface cards

TMcB — Tue, 14 Aug 2001 10:52:19 GMT

I have 2 network cards installed on my server -1000Base-SX and an ethernet card.
The 1000Base-SX is the only one currently connected.
Within SAM I have disabled the ethernet card, although it still knows the ip address, etc configured on it.

Meanwhile, on the console, I am receiving the error message- telnetd :connection reset by peer.
The only noticable thing from NETFMT is a problem with the interface card - check cable.

Is it possible that even though this card is disabled, that it is still trying to do something?
Can I remove this card altogether from system?

Thanks for any help

look at /etc/rc.config.d/netconf and delete the entries for your undesired lan card.

the do an /sbin/init.d/net stop and /sbin/init.d/net start and all configuration will ge gone

Hi,
find the lan number(x) for the ethernet using 'lanscan' command and make it down "netconfig lanx down". and also delete all the entries for ethernet in /etc/rc.config.d/netconf and do "/sbin/init.d/net stop/start"

Hi folks

lan0 is the unused card and lan1 is the Gigabit card.

Within netconf, interface_name[0] refers to lan0.
When I delete all the configurations marked [0]
should I leave the other one as lan1 and [1]
or do I change all entries for it to [0].

Thanks for your advice

Hi Terry

You should not change the entries to lan[0].
Also do a lanscan to confirm which card is lan[0] and which one is lan [1]

Hi Terry,

You should remove all your [1] entries and amend your [0] entries to reference lan1 and its settings. You'll end up with something like:-

INTERFACE_NAME[0]=lan1
IP_ADDRESS[0]=
SUBNET_MASK[0]=
BROADCAST_ADDRESS[0]=
LANCONFIG_ARGS[0]=
DHCP_ENABLE[0]=

John

i suppose that some sort of wierd interaction could result in the telnet connections being reset by the remotes, but i find it a bit unlikely.

if the remotes are PC's, many PC apps erroneously use abortive TCP closes - setting SO_LINGER settings such that a RST is used instead of a FIN . that could result in the telnetd reporting connection aborted by peer.
