Hello,

I need to collect some network information about TCP, IP, UDP and SCTP on
linux platform. About IP, I need to collect such as number of packets
received , packets transmitted, bytes received, bytes transmitted, bad
packets received, packet transmit errors, received packets dropped and
transmit packets dropped.
About TCP and UDP, I need to collect the number of connection opens,
segments received and so on.  About SCTP, I need to collect the number of
failed connection attempts, chunks received and so on.

I think i could get some of them from the file /proc/net/snmp. But for bytes
received and resets sent,  I do not know how to get it. And I don't know how
to get information about SCTP.

Could you tell me how I can get those inforamtion? Also, could I get thost
information by ioctl()? how?

Thanks very much!

try `netstat -s`, it's portable and would give you most of the
information you desire for protocols. As for interface statistics
(frames delivered, errors, etc), try `netstat -i`.

not sure if the linux netstat implementation is SCTP-aware though. as
for ioctls, maybe you need to look at the netstat code; my guess is, it
would be taking those values from /proc.

Vishal,

Thanks for your information!
The linux kernel I used is 2.4.  Could it support SCTP?
I have checked /proc, but didn't get the data for SCTP.

Thanks,
Ben

i've not worked with SCTP.. maybe you should try posting this on
comp.protocols.tcp-ip
