Determine Network Traffic on Openserver

[clegg]

I've got a customer who has to reboot his Unix (Sco Openserver) box every 3-4 days because his machine keeps falling over with out of streams messages.

If you do a netstat -m, you can see the figures building up continually over time. I have done some searching on the net and everything I've found seems to point to either a dodgy network card or increased network traffic.

Is there a simple way of monitoring the network traffic that is being aimed at this Unix box?? Its seems you can't do a snoop or tcpdump on Openserver!

Any help would be appreciated.

Which version of OSR (do uname -v)?
Which patches applied (do custom) ?
5.0.5 is known to have streams issues.

 

[clegg]

uname -v = OSR version is 5.0.5

custom = not found!

any clues?

 

[stanhubble]

make sure you are running as root when trying to run custom, otherwise try swconfig.

under netstat -m is there anything in the fail column?

On 5.0.5 it's strongly recommended to have rs505a and oss497c applied. As root, do a

 swconfig -P

to list all the patch applied on your system.
The official URL for SCO OSR pathes is:
ftp://ftp.sco.com/pub/openserver5/

Hope This Help

I have the exact same problem on my SCO server with 5.0.5. Streams keep being created and not released. I have to reboot every 2-3 weeks or the system will eventually lock up all TCP/IP opreations. On mine it is due to a bug in SCO that shows up when running Samba. The answer is Samba 3.0 which hopefully is due out soon. You can find more on this in google - search Samba SCO streams.
