Hi Laura: # Hi Albretch, i've some questions.. it's my first time!!! There are many examples on the web for that. Basically, say sudo apt-get install devscripts sudo apt-get build-dep freeradius apt-get source freeradius # Until this step all went well In the source folder, edit the file debian/rules and tweak the configure option. ### I've added the last line ./configure $(confflags) \ --prefix=/usr \ --exec-prefix=/usr \ --mandir=$(mandir) \ --sysconfdir=/etc \ --libdir=$(libdir) \ --datadir=/usr/share \ --localstatedir=/var \ --with-raddbdir=$(raddbdir) \ --with-logdir=/var/log/$(package) \ --enable-ltdl-install=no --enable-strict-dependencies \ --with-large-files --with-udpfromto --with-edir \ --enable-developer \ --config-cache \ --without-rlm_eap_tnc \ --with-rlm_sql_postgresql_lib_dir=`pg_config --libdir` \ --with-rlm_sql_postgresql_include_dir=`pg_config --includedir` \ --without-rlm_eap_ikev2 \ --without-rlm_sql_oracle \ --without-rlm_sql_unixodbc \ --with-system-libtool \ --with-dhcp ### Then edit the file debian/changelog and add an extra entry (like the others in the file) at the top, extending the version info by a "local" suffix, e.g. (for Ubuntu "saucy"; change according for your needs) <snip> freeradius (2.1.12+dfsg-1.2ubuntu5laura) saucy; urgency=low * add dhcp option for my server -- your name <your.mail@company.es> Tue, 24 Dec 2013 13:42:19 +0100 </snip> Then say debuild -us -uc -b which produces "freeradius-*-1.2ubuntu5laura" deb packages. Just install them... Remember that you should *not* automagically update ("apt-get upgrade") freeradius. Instead, whenever the package maintainers provide a new version, repeat the procedure above. ##### # I get the error code 1325, I've searched it and I think that it's because I don't put in the correct folder, is it? The route has been as follows: /etc/freeradius/freeradius-2.1.10+dfsg, where /etc/freeradius/ is the real installation on server, I 've seen in debian/rules: $(MAKE) -C dialup_admin DIALUP_PREFIX=/usr/share/freeradius-dialupadmin \ DIALUP_DOCDIR=/usr/share/doc/freeradius-dialupadmin \ DIALUP_CONFDIR=/etc/freeradius-dialupadmin \ R=$(freeradius_dir) install I must move the entire files of freeradius-2.1.10+dfsg to /etc/freeradius? another thing I've seen is you have to rename the original file to change the nomenclature, ie of freeradius-2.1.10+dfsg to freeradius_2.1.10+dfsg, is it the case?
