Telnet from Floating Self IP

Yes , Netcat can be used to generate all sorts of traffic including Udp and IPV6 type traffic . See examples below : nc -u -4 10.90.100.1 514 , the u option is udp , -4 option is Ipv4 and 514 is the port . In this example I am generating udp traffic for the syslog port 514 to test udp connectivity nc -t -4 10.90.100.1 443 - the t option is tcp , -4 option is Ipv4 and 514 is the port . In this example I am generating tcp traffic for the https port 443 to test tcp connectivity

Yes, nc can be used to generate the test traffic on any given port. HOWEVER... it fails when you use "-s [Floating-IP]" eg nc -v -z -s 10.1.1.2 10.3.4.5 80 ....works fine when .2 is the self-ip, however... nc -v -z -s 10.1.1.1 10.3.4.5 80 .... fails with nc: bind failed: Cannot assign requested address. Anyone know how to source the test traffic from a floating -IP ?
