How can I install linux-ftpd-ssl 0.17 on Fedora Core 6 ? Do I have to set any environment variables ? I downloaded the version from
http://www.brothersoft.com/ftpd-ssl-...ad-348469.html and tried to compile it but it is giving many errors. Please help
I need the above versions only.

Welcome to LQ.
The long term supported versions of the obsolete Fedora 6:
CentOS 5.4 / Scientific Linux SL54.

Have a look at your link for ftpd-ssl : it says ..
"" Homepage: http://www.debian.org/index.en.html ""
Go to the source http://packages.debian.org/source/lenny/linux-ftpd-ssl
.. to get the patch linux-ftpd-ssl_0.17.27+0.3-3.diff.gz
.. and to know all dependencies, and thus do :
# yum install pam-devel openssl-devel

Also have a closer look at the files, you downloaded,
and see they are marked 1997-2000. Compiling last century
software : Please use the patch .....
cd linux-ftpd-0.17/ && patch -p1 < linux-ftpd-ssl_0.17.27+0.3-3.diff
&& ./configure && make
..

After doing # yum install pam-devel openssl-devel, i am getting this error:

[root@localhost ~]# yum install pam-devel openssl-dev
Loading "installonlyn" plugin
Setting up Install Process
Setting up repositories
http://archive.fedoraproject.org/pub...ta/repomd.xml: [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>
Trying other mirror.
Error: Cannot open/read repomd.xml file for repository: core

Also I want to configure specifically the linux-ftpd-ssl with Buffer Overflow Vulnerability on Fedora6.

All http://archive.fedoraproject.org/pub/archive/fedora/
and http://archives.fedoraproject.org/pub/archive/fedora/
.. are not working these days.
( Some URL for Fedora 11 etc. : problems too.)
I guess, we will have to wait,
until they have finished the url changes.
EDIT: Just checked this url , it works

About using linux-ftpd-ssl : I have no idea how to use it.
