I have tried ISP Config and had it installed and functioning correctly but when browsing around I found another control panel. DTC which has a few more features, I think a beter layout, and looks as well. It has been installed on the following systems, and copied and pasted below. The DTC site is here:
http://www.gplhost.com/software-dtc_2screenshots.html
DEBIAN - Fully tested and working under Woody, Sarge and Sid. This is the main development platform so it's the best supported system. All sub-packages are available in our ftp (mod_log_sql, mysqmail, sbox-dtc, etc.). Please note that Woody support is to be stopped.
FREEBSD - An old version (0.12) is already in the FreeBSD port tree under /usr/ports/sysutils/dtc, but we suggest you switch to a newer version, 0.12 being very old. We did some tests with the 0.17.0-R4 of DTC, and the current port works perfectly with Apache2, mod_log_sql2 and php4 or 5. SBOX is ported too, in /usr/ports/www/sbox-dtc. We always need help in FreeBSD, mainly to fixup some bad path for this OS (using /usr/local mostly).
REDHAT - The latest versions have been tested and debugged for Fedora Core 3. It should work with no major problems, if you change the way your /etc/passwd is setup (they stupidly use nfsnobody for user 65534 instead of nogroup or nobody, and thas messes everything up...). Please understand that we can no longer support the old redhat system because the new one has changed too much. RedHat is to be blamed, not us...
MAC OS X Server - The package works, even if recompiling mod_log_sql and sbox involves administrator's work. There is currently no graphical installer, but there might be one soon.
GENTOO - DTC has been reported to work well by the one who contributed with small patches. Gentoo is now integrated in our multi-os build system, and its automated install script with pre-definited path is working. Complete ebuild package contributions are welcome as nobody from the dev team uses Gentoo.
There are some how-to's on installing it on CentOs, ubuntu and maybe one other. I have gotten used to using Suse and would like to keep it not only for the ease of use, somewhat familiarity with it, but also I have tried the other operating systems and they are giving my server problems. As well as the documentation they have is limited to a point and the support and forum activity is little to be desired. I would appreciate it if someone could help me with an install of DTC on my suse system.
