I guess it's old procedures that have changed names since the code was released. Anyway, I avoided those errors by making the following changes to ns-gnutella.tcl: -Substitute $node bind $tagent $port With $node attach $tagent $port -Substitute set port_ [$node bind $tagent 0] With set port_ [$node attach $tagent 0] -Substitute set bip [$lagent myipaddr] set bport [$lagent myport] With set bip [$lagent addr] set bport [$lagent port] This way I got the script to overcome that error. Anyway, many other issues open after this. If someone has experience in using the Tcp Socket code, please answer. I need to get this working and it looks like nobody is supporting the code right now. -- View this message in context: http://www.nabble.com/TCP-socket-support-for-NS2-tp16379848p25680954.html Sent from the ns-users mailing list archive at Nabble.com.
