Basic telnet and traceroute testing

Ravager

This might actually be a nice article for someone to write but I have some issues with telnet and traceroute on the f5.

 

I am assuming its possible to use these features like i do on a cisco switch by being able to specify a source ip and interface to go out on etc.

 

Let say i have the below with all GWs on .1

interface A

vlan2, 10.0.1.0/24 and vlan3 10.0.2.0/24

 

interface B

vlan 12, 10.1.1.0/24 and vlan 13 10.1.2.0/24

 

interface C MGMT

10.2.1.10 /24

 

how would i do a tracert from sources from each vlan using ip 10.x.x.6 as source (ie x being 10.0.1.6 10.0.2.6 10.1.1.6 10.1.2.6)

how would i do a tracert from the mgmt ip

 

how would i do a telnet on port say 1111 from each vlan using ip 10.x.x.6 as source

 

Reason i ask is we have a vary complicated network with multiple vendors administering various parts and while its easy to do these tests using a router sometimes its a router I dont have access to and it takes ages to request a 3rd party to do a the work. These tests are pretty much a standard for changing various Firewall rules around the network.

 

Cheers

as traceroute is just a linux tool the documentation gives some options, like to select an interface or source IP adres

same with telnet
