Re: [OT] Better Linux server platform: Redhat or SuSe?
I think the point is that you have complete non-trivial applications being
written in Perl.
Success is measured in application adoption, not in elegance. I've
worked many places that produced very elegant code, however all of those
places no longer exist. You need more than cool code to mark something
as a success.

Re: [OT] Better Linux server platform: Redhat or SuSe?
Since everyone's become distracted by the lines of code number, I answered a few of the questions that I feel I can answer. Apache/modperl installation and updates: I assume installation is straight forward, how about keeping current? As those are remotely administered platforms, chances are the OS may not be kept current. So is it still easy to deal with security updates (Apache, sshd, bind etc) when the platform is a couple of years old? With FreeBSD this has become somewhat harder lately (still running 3.x, but the ports system doesn't support 3.x any longer). You're talking about using their packages? I suspect most people on this list build their own apache/mod_perl binaries. Remote maintability: Is it possible to remotely upgrade between OS versions for either of those platforms (not a must, but would be a plus)? I would be afraid to do that remotely, since it normally involved a kernel change as well. Sendmail: Does the system make it easy to replace sendmail with another mailer of choice (qmail in my case)? I don't know about Red Hat, but it's certainly easy in SuSE. Footprint: Is it easy to weed out unused system components to have a smaller footprint of the OS? Or does that mean fighting the installer left and right? I don't know if Red Hat is getting any better, but I've always found it difficult to do a minimal install. SuSE has options for a very minimal install which is what I use for server installs. perl: Any iussues with perl/modperl? Besides modperl I will be running a perl application with a few hundred thousend lines of code... My current project: http://www.better-investing.org runs on Red Hat. I'm not aware of any perl/mod_perl issues, but I built perl and the apache binaries myself. I don't use their RPMs. Security: Is it easy to 'tie down' the system? The web site is behind a firewall and load balancers, so the web servers themselves don't have ipchains, etc. but they also aren't running any services available to the outside except http and ssh. Software-based RAID 1: Is it usable (only for a data partition, not required for the root partition)? Is it easy to recover from a broken disk? Robustness: While almost all systems I have are/will be on UPSs, they still tend to occasionally be 'unplugged' (not shut down cleanly), be it due to an empty or dead UPS battery, someone tripping over or accidentaly unplugging the power cable etc. etc. Does the system tend to survive the then due fsck without manual intervention? Better yet, would it be possible to mount / and /usr read-only, and have a /var partition that (if the worst should happen) can be recreated on the fly? Can't help you on RAID, but I have found SuSE with ext3 or ReiserFS to be VERY recoverable. -- Barry Hoggard Tristan Media LLC e: [EMAIL PROTECTED] p: 212-627-1596 aim: hoggardb

Re: [OT] Better Linux server platform: Redhat or SuSe?
I'm using RedHat on my servers; can't do comparison to SuSe since I don't know it, but I'll comment on the RedHat side. I got into RedHat because of the RPM utility, around 4.2 I think, and have stayed with it because nothing has yet annoyed me enough to switch. Gerd Knops [EMAIL PROTECTED] writes: Besides general observations I am specifically interested in answers to these questions: Apache/modperl installation and updates: I assume installation is straight forward, how about keeping current?

With FreeBSD this has become somewhat harder lately (still running 3.x, but the ports system doesn't support 3.x any longer). I'm still with RPMs for these components, and am hoping intensely to be able to stay there because it's *so* easy to keep up to date. Remote maintability: Is it possible to remotely upgrade between OS versions for either of those platforms (not a must, but would be a plus)? Yes. I'm assuming you understand it's always dangerous to do this; do you at least have people who you can call on the phone to push the reset button if you screw up? With the GRUB loader that's appeared in recent RedHat's, the biggest easy mistake has gone away (you no longer have to do the equivalent of running lilo before rebooting). Of course if the new kernel itself doesn't boot, you're sunk (need somebody at the console to select an alternate boot kernel). The last umpteen kernel upgrades I've made, I've never screwed up badly enough to need to use the reset button, and since the systems are physically right in front of me I haven't been all that careful. I haven't done this, but it looks like it's possible to configure a RedHat system to boot with serial console. If you have the sort of facilities I consider normal for a multi-continental WAN, can you tie the serial port of your server machine to a terminal server and get remote access to the console? That would work around most of the problems with remote maintenance. Sendmail: Does the system make it easy to replace sendmail with another mailer of choice (qmail in my case)? Not as easy as it should be, but perfectly possible. I'm installing qmail from source, so I have to override the dependencies in several RPMs for mailerdaemon. An alternative would be to build your own qmail rpms and have them provide that dependency. So far I've found that you can't make redhat install new without sendmail, but it's easy to rip out once the new install is done. I haven't found it appearing on upgrades, anyway. (I'm also using qmail). Footprint: Is it easy to weed out unused system components to have a smaller footprint of the OS? Or does that mean fighting the installer left and right? For initial installs, you can pick each package individually. Of course that's a very long list to review. After the initial install, you can remove packages very easily (one of the great benefits of RPM). On upgrades, it only upgrades packages already installed (and may ask to bring in dependencies, if they've changed). perl: Any iussues with perl/modperl? Besides modperl I will be running a perl application with a few hundred thousend lines of code... I'm not stressing it hard enough to tell. The RPM version is working fine for me, but I'm new to mod_perl, don't have much using it yet. Security: Is it easy to 'tie down' the system? No harder than any other system, anyway. The /etc/rc.d/init.d structure for controlling subsystems is very useful; that and xinetd are the two places anything is likely to be started. And tools like netstat are around (I like to check and make sure nothing I don't know about is listening to ports, for example, as a sanity check that I've really limited it to the things I want.) Software-based RAID 1: Is it usable (only for a data partition, not required for the root partition)? Is it easy to recover from a broken disk? I'm using it on my primary web server for the user/web partition, seems to work fine. I've survived a broken disk and a broken controller, I think. (With today's prices, I tend to discard questionable components rather than pursuing diagnosis in detail.)

Re: [OT] Better Linux server platform: Redhat or SuSe?
Software-based RAID 1: Is it usable (only for a data partition, not required for the root partition)? Is it easy to recover from a broken disk? If possible, consider using hardware RAID, like Mylex ones; they are quite expensive, because of SCSI disks, but you gain cpu cycles; I've used Mylex cards on four Red Hat boxes for four years without a problem, and monitored hw status using /proc file system. There are also IDE motherboards with RAID, I own one of them, but I use the eight devices feature instead of raid. Consider also the use of kickstart utility shipped with RH, it makes possible to build your own installation disks; of course, Debian also is very powerful at this. I never used RH RPMs for Apache and mod_perl, mostly because of DSO issues. You can also build a card to operate reset buttons remotely.

Re: [OT] Better Linux server platform: Redhat or SuSe?
We wrote our own templating system (back when modperl was still just a puppy) as we have over 200 sites running off the same code instance distributed across the server farm. Everybody wants their submit buttons to say something slightly different, we were forced early on to remove all hardcoded html from the code. The reason for all that code is that there is just a lot of functionality there (text analysis, vectorspace matching, billing, customer management, message system). Much of it has been migrating into our java-based backend system (I'm sure a year ago the number of lines of code would have been substantially higher) as we retire all the business logic that was embedded in the modperl frontend and maintain only the java version which runs in the backend.

[OT] Better Linux server platform: Redhat or SuSe?
Hi, Sorry for this somewhat OT post (though it may be of general interest). I am currently maintaining a WAN (4 continents) consisting of FreeBSD machines. While I am quite happy with FreeBSD, lack of driver support for some boards I need to use forces me to switch to Linux. And while the Pros often seem to favor Debian, the drivers I need (binary only) seem to be best tested with/easiest available for Redhat and SuSe, which is why I am looking especially at those two. This is strictly for server use, so problems with X, compatibility with new-fangled video boards and other Desktop-OS related problems are not the issue here. Besides general observations I am specifically interested in answers to these questions: Apache/modperl installation and updates: I assume installation is straight forward, how about keeping current? As those are remotely administered platforms, chances are the OS may not be kept current. So is it still easy to deal with security updates (Apache, sshd, bind etc) when the platform is a couple of years old? With FreeBSD this has become somewhat harder lately (still running 3.x, but the ports system doesn't support 3.x any longer). Remote maintability: Is it possible to remotely upgrade between OS versions for either of those platforms (not a must, but would be a plus)? Sendmail: Does the system make it easy to replace sendmail with another mailer of choice (qmail in my case)? Footprint: Is it easy to weed out unused system components to have a smaller footprint of the OS? Or does that mean fighting the installer left and right? perl: Any iussues with perl/modperl? Besides modperl I will be running a perl application with a few hundred thousend lines of code... Security: Is it easy to 'tie down' the system? Software-based RAID 1: Is it usable (only for a data partition, not required for the root partition)? Is it easy to recover from a broken disk? Robustness: While almost all systems I have are/will be on UPSs, they still tend to occasionally be 'unplugged' (not shut down cleanly), be it due to an empty or dead UPS battery, someone tripping over or accidentaly unplugging the power cable etc. etc. Does the system tend to survive the then due fsck without manual intervention? Better yet, would it be possible to mount / and /usr read-only, and have a /var partition that (if the worst should happen) can be recreated on the fly? Any other oddities one should be aware of? Thanks much for any input Gerd
