A socket is the combination of an IP adress and a port number. E.g when you browse some homepage you make a TCP connection to a destination socket say "192.168.1.1, 80". But in order to get data from the webserver you (the client) must also have a socket, a source socket, say "192.168.21, 3032".

Networking is not a simple subject so I suggest you go buy a book or start reading some network tutorials if you want to know more.

hope this helps

NAME
watchgnupg - Read and print logs from a socket SYNOPSIS
watchgnupg [--force] [--verbose] socketname DESCRIPTION
Most of the main utilities are able to write their log files to a Unix Domain socket if configured that way. watchgnupg is a simple lis- tener for such a socket. It ameliorates the output with a time stamp and makes sure that long lines are not interspersed with log output from other utilities. This tool is not available for Windows. watchgnupg is commonly invoked as watchgnupg --force ~/.gnupg/S.log OPTIONS
watchgnupg understands these options: --force Delete an already existing socket file. --tcp n Instead of reading from a local socket, listen for connects on TCP port n. --verbose Enable extra informational output. --version Print version of the program and exit. --help Display a brief help page and exit. EXAMPLES
$ watchgnupg --force /home/foo/.gnupg/S.log This waits for connections on the local socket '/home/foo/.gnupg/S.log' and shows all log entries. To make this work the option log-file needs to be used with all modules which logs are to be shown. The value for that option must be given with a special prefix (e.g. in the conf file): log-file socket:///home/foo/.gnupg/S.log For debugging purposes it is also possible to do remote logging. Take care if you use this feature because the information is send in the clear over the network. Use this syntax in the conf files: log-file tcp://192.168.1.1:4711 You may use any port and not just 4711 as shown above; only IP addresses are supported (v4 and v6) and no host names. You need to start watchgnupg with the tcp option. Note that under Windows the registry entry HKCUSoftwareGNUGnuPG:DefaultLogFile can be used to change the default log output from stderr to whatever is given by that entry. However the only useful entry is a TCP name for remote debugging. SEE ALSO
gpg(1), gpgsm(1), gpg-agent(1), scdaemon(1) The full documentation for this tool is maintained as a Texinfo manual. If GnuPG and the info program are properly installed at your site, the command info gnupg should give you access to the complete manual including a menu structure and an index.
