When I set "HOME_NET" to anything other than 'any' I no longer see any DOS or DDOS alerts but P2P alerts are still output.
Depending on how the P2P rules in question are written, that will still be the case. If you don't want to know which of your hosts in $HOME_NET are using P2P services, why do you have the rules enabled?
I've tried following the configuration examples in the FAQ's etc and
can't
get it to work. I'm wondering if HOME_NET has any relevance when running snort in 'stealth' or am I wide of the mark?
You're wide of the mark. Running the sniffing interface with no IP address has no interaction with HOME_NET, whether it's left at 'any' or not. :-)
Also - can snort cope with variable length subnet masks?
Looks like it, from reading the source for ParseIP() in parser/IpAddrSet.c. I'd be surprised if it doesn't handle VLSM flawlessly, just as I was surprised when Solaris still didn't back around '98/99 or so.
