vserver ALWAYS replies to ping

Hi,

 

 

Any of you know if there is any other way to implement that VS don't repond to TCP / ICMP connection when the pool don't have active memebers ?

 

 

For me the tcping / telnet all works , even if the pools is marked down

 

 

Highly appreciate your help

 

 

thanks

For TCP, it should respond with a reset if all the pool members are down (unless you have a last chance redirect configured, in which case the session should handshake, the redirect occur, and then the close). With ICMP, it should always respond, because ICMP is attached to the IP address, whereas a virtual is an IP address and a port. Many virtuals could (and often do) exist on a single IP address, so you wouldn't want ICMP services to fail for the other virtual servers.

A common issue with this type of thing is that you've got an HTTP profile bound to that virtual server, but you want it to RST if the pool members are down. If this is the case, the virtual will stand up a socket no matter what, as it's waiting for the HTTP data to come in to start parsing. If the pool members are down it'll send the RST, but only after the HTTP parser on the LTM parses the request.

 

 

A standard TCP profile should not do this though - it should send a RST if the members are down, as Jason notes above.
