MP1, Redhat 7.3: Transmission size limited after some time
Hi all,
I got a really odd problem: I have identical mod_perl/apache installs
on FreeBSD 3.x systems and a few Redhat 7.3 systems.
After some time running OK, the Redhat systems start acting up.
Transmissions are suddenly cut of after somewhere between 90 and 150
kb. Absolutely nothing in any logs is indicating a problem. Dynamic web
pages sent via print are affected the same as downloads sent via
$r-send_fd('FH');.
Restarting the web server fixes it, but a few hours/days later the
problem resurfaces. Anyone encountered something similar? Any pointers
as to how to debug this? I have ruled out problems with external
hardware or proxies, as that problem occurs equally on systems in
radically different environments.
Thanks for any pointers

[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

When I checked into this Raven SSL seemed to be the solution. It is basically mod_ssl with an RSA license. Some people also suggested that if you buy the Red-Hat server package (or whatever it is called) which includes a RSA license, you could just put it into a corner and use mod_ssl. But I am not sure if that kind of 'license transfer' is really legal. Gerd
