Maybe it's an idea to make this an per-interface value. On my local GigE=20 NFS network it might not be useful (well, maybe even lowering the=20 performance), while on another interface with lots of connects from all=20 over the world does a good job. Dunno, it's probably not so easy to implement this, then. - Oliver --=20 | Oliver Brandmueller | Offenbacher Str. 1 | Germany D-14197 Berlin | | Fon +49-172-3130856 | Fax +49-172-3145027 | WWW: http://the.addict.de/ | | Ich bin das Internet.
