!! 3. TCP process identification number
-TCP/IP has ports which when associated with an IP identify uniquely one end of a [TCP] (or [UDP]) connection. Some ports are 'well known' and by convention programs listen on them, for instance port 22 by convention will have an ssh daemon listening on it. /etc/services (services(5)) lists all these ports.

+''Most wiki's I've found allow exporting for backup, for instance this wiki (which is a Php Wiki) allows export as [MIME] files, and many allow importing from flatfiles, however most of them have different markup, so although you can get information between them, you can't easily get them to keep all the markup etc you used before'' -- PerryLorier
