listen to multiple IPs(clients)

[ligerdave]

Folks,

I would like to set my memcache instance to listen to only a list of
given IPs.

I know you can specify an IP/interface by using -l 127.0.0.1. Is it
possible to do something like this: -l ip1,ip2,ip3

I was trying to find its source code for stddup(), the piece dealing
with -l argument. Does anyone know where to find it?

It is copied at: http://github.com/memcached/memcached/blob/master/memcached.c#L4384

but you may want to look at where it's used:

http://github.com/memcached/memcached/blob/master/memcached.c#L3824

so is it possible to use -l ip1,ip2,..... ?

No, you asked for where in the code it used the -l argument, and memcached does currently not tokenize the argument to -l.

@ligerdave,
  i think you meant strdup() ..its string duplicate function ( more info : man strdup )

Does that mean memcahed can be set to listen on either Single IP or ALL IPs , but no to fixed pool of IPs ?

Yes. If you look at one of the last link i added in my first response you would see how the -l argument is handled. It should be fairly simple to modify the code to tokenize the string and bind to each of the ip's you specify.

is this planned to be included in any quick official fix or
improvement? you know this could be a headache if i have to modify/
build the code every time when there is new release.

@Manoher, yes, it's a typo. however, actually i meant to type
getaddrinfo().

@Trond, i just realized that i typed strdup here. i was indeed looking
for getaddrinfo()
