Subject: [tcpdump-workers] pcap_open_live errorHey guys, i posted this problem yesterday and have a few more questionsThe original problem is thisI 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 ispcap_open_live snoop bind Cant assign requested addressI 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 fail3)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 wayJason
