Re: Newbie can't log into his own wu-ftpd server from PowerBook G4 (Mac OS X 10.2.8)

for debian :
if you want to recompile without the dns feature
you would have to type something like :
   apt-get source wu-ftp
it will download the source tree in the directory where you are, so try 
to go in /usr/src/wu-ftp (with a mkdir wu-ftp)
then you would be able to find a file that is the way
i get the following :
jpl:/usr/src/wu-ftp# ll
total 348
-rw-r--r--    1 root     src             0 Feb 28 11:58 
wu-ftpd_2.6.2-3woody2.diff.gz
-rw-r--r--    1 root     src             0 Feb 28 11:58 
wu-ftpd_2.6.2-3woody2.dsc
-rw-r--r--    1 root     src        354784 Mar  7  2002 
wu-ftpd_2.6.2.orig.tar.gz
one is the official distro (orig.tar.gz)
the diff.gz file is the debian patch
the other is nothing
1 - decompress the orig
2 - apply the patch with something like " patch -p1 --verbose --dry-run 
< wu-ftpd_2.6.2-3woody2.diff.gz " (not sure of the command) (use dry-run 
until you are sure of the command)
3 - this diff file should configure every defaut debian option that make 
wu-ftp be compiled as you normally have it in binary form : read README 
and INSTALL to find out how to disable DNS and compile as explained
