Since we are down to one machine for all our home needs, I have reconfigured gucho.kiriz a lot now. There is no more need for the .kirzis domain, thus it will be known as gucho.mamchenkov.net from now on. A bunch of useless services like dhcpd, nfs, and pormap were stopped. Firewall, web server, proxy server and mail server were reconfigured to dispose of internal IP addresses and .kirzis domain.
I have also upgraded all the software on gucho and installed a whole bunch of new packages, so that it appears as a useful workstation. With all the software available these days for Linux, I found Synaptic to be very useful.
If you notice any misbehavior with the site or the server, please let me know.
