Hey guys, i posted
this problem yesterday and have a few more questions
The original problem
is this
I am writing a
program on an IRIX 6.5 machine that uses the libpcap to grab packets. That
usually works fine. However i have now decided that this program needs to have
multiple child processes. So i decided to have each child call the
"pcap_open_live" function. This is where the problem stems. IF i
comment out the "pcap_loop" line that EACH child runs then pcap doesnt return
any error. Remember the pcap_loop call is AFTER the "pcap_open_live"
call. However if that line is enabled, so i can use pcap for packet
capture, i get an error on the "pcap_open_live" call. the error
is
pcap_open_live snoop bind Cant assign requested
address
I have been working
on this problem and have some questions.
1) Why would
it work when the pcap_loop is commented out, ie i have tried it with up to 10
children when the pcap_loop line is commented out and it works fine.. ie no
error.
2) Why would a line
that is "after" the code that is generating the error cause this.
Basically what i am wondering is when all the code is "enabled" the
pcap_loop line causes the pcap_open_live call BEFORE it to
fail
3)Could it be that
having multiple process call the pcap_open_live not work, but it that is the
case then why would everything seem to be ok when the pcap_loop line is
commented out.
I would appreciate
any help, i am already try to get ahold of SGI to see if it is something
wierd...per an early suggestions Thank you by the way
Jason
