Subject: NIC Goes Down After 5-10 minutes in rh6.2
Hi
I have RH6.2 full without updates or patches running on Pentium 1 100mhz
24mb of ram. I have a strange problem with network. That machine has 3Com
Etherlink 3 NIC 10mbps. it is configured to get interface up at bootup. It
brings up the inerface it is works. But After 5-10 minut it is goes down. I
preform:
if config eth0 down
if config eth0 up
it replies:
eth0: Setting Rx mode to 0 adresses.
eth0: Setting Rx mode to 1 adresses.
There is not enough information to say what the hell is going on.
I suggest you to rebuild debug version of the driver and to post all
debug messages it prints.
To do that ( I hope the driver is module, otherwise you will have to
recompile the kernel
as well and to remove the driver from static code and to move it to be a
module ):
Set kernel logger output to unused console.
To do that, go to /etc/syslog.conf and add line that says:
---
*.* /dev/tty8
*.* /tmp/kernl.out
---
Tabs are important.
restart syslogd ( "/etc/rc.d/init.d/syslog restart" )
This will dump _all_ messages from kernel and system to /dev/tty8 ( alt-f8
will bring you there ).
Then open the code for driver ( /usr/src/linux/drivers/net/3c509.c ) and
edit line 74 and 76
change line 74 from
--
int el3_debug = EL3_DEBUG ;
--
to
--
int el3_debug = 9 ;
--
and line 76 from:
--
int el3_debug = 2;
--
to
--
int el3_debug = 9 ;
--
Recompile the driver with command:
gcc -DMODULE -D__KERNEL__ -Wall -Wstrict-prototypes -O2 -c 3c509.c
then bring the card down, remove module
insert the newly built module and bring the interface up.
Then look for all messages from eth0 on tty8 ( or file /tmp/kernl.out ) and
send them to me/list.
I have tryed to debug the problem as you said. but something gone wrong. After restarting the syslog there was no file kernl.out in /tmp directory and alt+f8 gives nothing. I did exactly as you say please check it may be you missed something.
Best Regars S.A.
and start work again for about 5-10 minutes.
If I am trying to use ftp server to upload or download something it is going
down Emidiatly.
What is wrong ?
