RPMGOT

Software package download proxy rpmgot is a simple/lightweight software package download proxy. It was designed to run on an OpenWRT router with some USB storage. So it is fully implemented as an ash script. The basic idea has been implemented multiple times. For example refer to this article on a squid based implementation. Unlike squid, which once you include all its dependencies can use up over 1MB of space just to install it, this software has very few dependencies. The idea is for small developers running the same operating system version(s) would benefit from a local mirror of them, but they don't have so many systems that it's actually reasonable for them to run a full mirror, which would entail rsyncing a bunch of content daily, much of which may be packages would never be used. rpmgot implements a lazy mirror something that would appear to its client systems as a full mirror, but would act more as a proxy. When a client installed a particular version of a particular package for the first time, it would go fetch them from a "real" mirror, and then cache it for a long time. Subsequent requests for the same package from the "mirror" would be served from cache. ...

So when upgrading software packages sometimes you need to merge changes. My recipe in archlinux is as follows: Look for *.pacnew files. Retrieve the original version (from /var/cache/pacman) from the old source package. Use a 3 way merge tool between old version, current file and the pacnew file. ...

Remote Bridging

Sometimes we need to connect two or more geographically distributed ethernet networks to one broadcast domain. There can be two different office networks of some company which uses smb protocol partially based on broadcast network messages. Another example of such situation is computer cafes: a couple of computer cafes can provide to users more convinient environment forr playing multiplayer computer games without dedicated servers. Both sample networks in this article need to have one *nix server for bridging. Our networks can be connected by any possible hardware that provides IP connection between them. Connecting Two Remote Local Networks With Transparent Bridging Technique Short description In described configuration we are connecting two remote LANs to make them appearing as one network with 192.168.1.0/24 address space (however physically, presense of bridges in network configuration is not affecting IP protocol and is fully transparent for it, so you can freely select any address space). Both of the bridging servers has two network interfaces: one (as eth0 in our example) connested to the LAN, and second (eth1) is being used as transport to connect networks. When ethernet tunnel between gateways in both networks will be bringed up we will connect tunnel interfaces with appropriate LAN interfaces with bridge interfaces. Schematically this configuration can be following: ...

First steps...

So finally took the time to re-launch the 0ink web site. This time used more off-the shelf software. So this site is just a another plain wordpress powered site. Actually I have to thank my son for introducing me to wordpress. What happened is that my son, who is only seven wanted to have his own web site. (Due to peer pressure, kids these days...) He has an Android tablet that he uses quite often. Since I knew that wordpress can be ...
