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!
