removable hdd caddy specs
Hi there, I thought that people on this list are the most likley to use removable drives, so here goes. Is there a standard specification for drive caddies? i.e. should i be able to take my drive out and put into another machine, even though the bays are made by different people? -- Thanks, -- -0) Hereward CooperBeing Alone Draws Attention Somerset, UK /\\ [EMAIL PROTECTED] GPG: 1E1D0C80 zadok.ddts.net _\_v -- msg05979/pgp0.pgp Description: PGP signature
Raid 1 Newbie
Hi there, I'm a newbie to raid, and want clarification on some issues. I'm setting up a Raid 1 consisting of 2 IDE 40Gb seagate drives. I've read through http://linuxdoc.org/HOWTO/Software-RAID-HOWTO-4.html are am a bit lost. [Also I don't want to risk playing around since there is important stuff on this machine]. What do I need to do, if I can, to boot off a raid1?

Netscape Roaming Access
Hi!
I've installed slapd 2.0.23-2 on linux debian with apt-get install.
After that I edited the configuration files and a netscape-profile.schema.
Then I edited entrys into the database with ou=People and ou=roaming.
It works well.
Subsequent I enable the Roaming Access for Netscape and set the
server information.
I selectet the items Bookmarks, Cookies, Mail Filters, Adress Book,
user Preferences and History to transferred to the database.
After I restarted Netscape Comunicator I login with my LDAP - Password
but when I shutdown the comunicator, the database dosen't
save my Bookmarks, Cookies, etc.
Any ideas what is wrong?
Thanks in advance,
Tamara

Re: [Apc-cache] Problem with apc and apachectl
You're leaking semaphores, APC doesn't seem to always clean up after itself gracefully. Do an apachectl stop, then execute the following command: ipcs -s -t | cut -f 1 -d | egrep ^[0-9]+$ | xargs ipcrm sem WARNING: if you have anything else on your system that uses semaphores, this could be trouble! On my system it works fine, but on yours it might not. Never do an apachectl restart or apachectl configtest, as these seem to be guaranteed to leak semaphores. I think if you do apachectl stop and wait a few seconds, it actually cleans up properly. You have to get a clean slate first though, so stop apache and run the above command to clean up the mess, and from now on always stick to start and stop, never restart. That's my experience, anyway... I haven't looked at the code for it, so I don't know exactly what's going on in there.

apache BASIC authentication w/large userbase
I have a customer who requires BASIC authentication for their site. They have a fair amount of traffic as well as a very quickly growing userbase. They were on mod_auth_mysql before, but with hundreds of apache children that is not very practical. I suggested a change to a signed-session-cookie type system, but they would not go for that because apparently a disproportionate number of their end-users disable cookies in their web browser. Stupid media privacy paranoia. The userbase is presently around 100K and growing 5K/day or so. They were having things go so slowly that users could not login. In the short term we replaced mod_auth_mysql with an apache module I whipped up to send requests out via UDP to a specified host/port, and wait for a reply (with a 3 second timeout). Then I hacked out a quick Perl program to handle those requests, hit mysql for actual user/password info, and to cache the user information in ram for the duration of the daemon's lifetime. Obviously this won't work forever without a serious change to my caching strategy, but before I put more work into this mechanism, what do other folks on the list do for high-traffic, large-userbase BASIC authen? I know it's a poor limitation but *shrug* the customer knows their needs. I figured DBM would be sluggish, and the customer already tried text files, but moved to mod_auth_mysql when that ran out of steam.

Re: Is mysql 3.2x stable enough for HA requirement?
Hello Jean-Francois Dive [EMAIL PROTECTED], I have no problem with the robustness of PostgresSQL. However, does PostgreSQL have built-in replication? If not, how do I implement high-available PostgreSQL clusters? In addition, since InnoDB has been stable in MySQL-3.23.49, is InnoDB ready for production?

[...]
The userbase is presently around 100K and growing 5K/day or so. They
were having things go so slowly that users could not login.
my rule of thumb is:
any site that requires 1000 username:password pairs uses AuthUserFile
and plain text .htpasswd files. any larger site uses AuthDBUserFile,
with username:password pairs in a hashed db (which is generated from the
plain text file). a hashed db is ideally suited to this task, it's a
simple key/value (i.e. username/password) fast, indexed lookup.
using AuthDBUserFile is a lot faster, and a lot less overhead (memory,
file handles, etc) than the mysql or pgsql authentication modules.
apache comes with a program called dbmmanage which can be used to manage
hashed db files. see the man page for more details. it's pretty slow,
though, because it's a general purpose tool. if all you need to do is
convert a plain text .htpasswd file into a corresponding .db file then a
5-10 line perl script could do the job many times faster.
e.g. something like:
#! /usr/bin/perl
use DB_File;
$filename=passwd.db;
# create the .db in a temporary file and rename it when it's done.
# rename is an atomic operation.
tie %passwd, 'DB_File', $filename.tmp, O_RDWR|O_CREAT, 0644, $DB_HASH ;
while () {
chomp ;
($key,$value) = split /:/;
$passwd{$key} = $value;
};
# untie the handle, close the file and flush all records to disk.
untie %passwd;
# move the .db file into place.
rename $filename.tmp, $filename;
on a busy P3-450 webserver, this script takes about 14 seconds to
convert a .htpasswd file with 35,000 entries into a hashed db file.
apache's dbmmanage takes over 90 seconds to do the same job.

Re: Is mysql 3.2x stable enough for HA requirement?
El Thu, Apr 04, 2002 at 08:58:50AM +0800, Patrick Hsieh escribió: Hello Jean-Francois Dive [EMAIL PROTECTED], I have no problem with the robustness of PostgresSQL. However, does PostgreSQL have built-in replication? If not, how do I implement high-available PostgreSQL clusters? Umm, AFAIK, 7.X series of PostgreSQL have built-in support for table replication, check de features page at their site to confirm. No matter if native supported or not .. there are some *load balancing* daemons around Inet, that let you setup a group of psql servers. Time ago I worked with one of that daemons and did this config: Node A:Node B: Node C: Node D: psql psql psqlpsql Daemon setup: Daemon Setup: Daemon Setup: Daemon Setup: Rep. to B Rep. to A Rep. to A Rep. to A Rep. to C Rep. to C Rep. to B Rep. to B Rep. to D Rep. to D Rep. to D Rep. to C It worked, but it's a big problem to have them perfecly in sync, because if you use RR at the dns level to do another *load balancing* task, uff, get harder to sync, beleive me. The best, if you target is HA and not Load Balancing is this one the same as above, but not doing DNS RR, instead, DNS failover, if master fails, slave get on running. Easier to keep in sync, because all the sql statements goes from Master to Slaves, if master goes down, one of the slaves becomes master and all contine running. In this aproach, a *faster* solution is to do IP takeover, if master an slaves are on the same subnet. Best Regards -- _ _ // Raúl A.
