FTP via F5

Is there any way to determine whether there is any (live) FTP traffic passing through an F5 load balancer?

Hi Michael,

 

You could check the connection table on the cli:

tmsh show sys connection

 

Cheers,

Hi Kees,

 

Thanks for your feedback.

Some questions:

 

1. After the connection table (from executing tmsh show sys connection) has been displayed, should I press Ctrl-C, in order to return to the command prompt?

 

 

2. The output, shown below, indicates that there is zero live FTP traffic, right?

 

user01@(LB01)(cfg-sync In Sync)(Active)(/Common)(tmos)# show sys connection cs-client-port 21

Sys::Connections

Total records returned: 0

Hi Kees,

 

3. Is there a quick way to determine whether any existing virtual server(s) in an F5 load balancer is configured to use an FTP profile?

Hi Michael,

 

this will first search for all FTP profiles (including default FTP profile) , then search all VS that have attached any of the FTP profiles and then list the name of the VS which has an FTP profile attached.

Run in bash:

for FTPprofile in $(tmsh list ltm profile ftp one-line | awk '{ print $4 }'); do tmsh list ltm virtual one-line | grep -E $FTPprofile | awk '{ print $3 }' ; done

Hi Daniei,

 

Thanks for your feedback.

The output below indicates that there are 2 existing virtual servers that have FTP profile(s) attached, right?

 

[root@LB01:Active:In Sync] config # for FTPprofile in $(tmsh list ltm profile ftp one-line | awk '{ print $4 }'); do tmsh list ltm virtual one-line | grep -E $FTPprofile | awk '{ print $3 }' ; done

Hi Michael,

 

yes, those should be all the VS with a FTP profile.
