Re: [Iperf-users] 2.0.5b1 iperf runs beyond time limit too

[Donnelly, J. <joh...@hp...>]

 Thanks Jon.

 The 2.0.5b1 behaves the same way in that a process runs 
 longer than desired (note 687 seconds) : 


Starting 4o iPerf Mon Apr 19 15:03:09 CDT 2010
 ====== 4o =====
ssh -f -l root 10.10.50.2 iperf -w 256k -f M -t 60 -c 110.110.60.11

I'm assuming the process is missing SIGARLM, however I don't see 
how it is being handled in the program.  Caught signals are sent to 
a function "Sig_Interupt" or "my_signal" .. which I don't seem to have the source to:

[root@donnbay05 src]# egrep "my_sig|SIGALRM|Sig_Int"  *

main.cpp:    my_signal( SIGTERM, Sig_Interupt );
main.cpp:    my_signal( SIGINT,  Sig_Interupt );
main.cpp:    my_signal( SIGALRM,  Sig_Interupt );
main.cpp:void Sig_Interupt( int inSigno ) {
Server.cpp:void Server::Sig_Int( int inSigno ) {
service.c:    Sig_Interupt( 1 )

I
How does the test terminate ? 

Suggestions welcomed.

Iperf 3.x is alpha quality at this point.  I'd wouldn't suggest it for actual use just yet.  I just hired a summer intern who will be working with me to get Iperf 3 up to snuff.

I'd suggest the 2.0.5b1 release I made two weeks ago:
