* Summer of Code 2005: improve libalias - part 1 of 2piso2006-09-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the first part of my previous Summer of Code work, we get: -made libalias modular: -support for 'particular' protocols (like ftp/irc/etcetc) is no more hardcoded inside libalias, but it's available through external modules loadable at runtime -modules are available both in kernel (/boot/kernel/alias_*.ko) and user land (/lib/libalias_*) -protocols/applications modularized are: cuseeme, ftp, irc, nbt, pptp, skinny and smedia -added logging support for kernel side -cleanup After a buildworld, do a 'mergemaster -i' to install the file libalias.conf in /etc or manually copy it. During startup (and after every HUP signal) user land applications running the new libalias will try to read a file in /etc called libalias.conf: that file contains the list of modules to load. User land applications affected by this commit are ppp and natd: if libalias.conf is present in /etc you won't notice any difference. The only kernel land bit affected by this commit is ng_nat: if you are using ng_nat, and it doesn't correctly handle ftp/irc/etcetc sessions anymore, remember to kldload the correspondent module (i.e. kldload alias_ftp). General information and details about the inner working are available in the libalias man page under the section 'MODULAR ARCHITECTURE (AND ipfw(4) SUPPORT)'. NOTA BENE: this commit affects _ONLY_ libalias, ipfw in-kernel nat support will be part of the next libalias-related commit. Approved by: glebius Reviewed by: glebius, ru

* Add Cisco Skinny Station protocol support to libalias, natd, and ppp.marcus2003-09-231-0/+25
| | | | | | | | | | | | | | | Skinny is the protocol used by Cisco IP phones to talk to Cisco Call Managers. With this code, one can use a Cisco IP phone behind a FreeBSD NAT gateway. Currently, having the Call Manager behind the NAT gateway is not supported. More information on enabling Skinny support in libalias, natd, and ppp can be found in those applications' manpages.
