UISP's latest release is 20050207. You can download it from here.
Once you've finished downloading it, go to the directory where you saved it and uncompress it:
you@there~$ tar -xzvf uisp-20050207.tar.bz2
A new directory called uisp-20050207 will be created after that. In that directory, run:
you@there:uisp-20050207$ ./configure you@there:uisp-20050207$ make root@there:uisp-20050207# make install
The last command has to be run as the superuser, the files will be installed in /usr/local, if you'd rather not have to be super user, or install it somewhere else, you can use:
you@there:uisp-20050207$ ./configure --prefix=/your/dir you@there:uisp-20050207$ make you@there:uisp-20050207$ make install
If you just want to have a look at the code, you can Browse UISP's CVS online. To get UISP sources from CVS, you should create a directory e.g. /home/you/sources. Then change to that directory and issue this command:
cvs -z3 -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/uisp loginJust hit ENTER for the password.
cvs -z3 -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/uisp co uisp
After all the files are downloaded, you'll need to create the configure script by calling ./bootstrap. Then follow the instructions on how to install the usual source code.
