Hi guys Does anyone have script ringdump-1-227589569.pl which is working??? I would need (just the part with tcpdump) it for reverse debugging on some customer installations.

 

The whole script is published here https://github.com/vincentmli/F5-iControl-Perl/blob/master/ringdump-1-227589569.pl

 

Thanks
