I was going nuts with one client (who thought he knew LDAP just because he had done a prototype setup on a Mac OS X server) because he was mucking around with the DIT (on the Mac platform). That is when I switched him to openLDAP and smbldaptools on Linux and reclaimed my sanity :) Another tool that I forgot to mention is LDAP Account Manager (lam); there is an open source as well a commercial support version. It is web based; ideal for the CLI phobic admins. You can delegate authority to non technical staff like HR for disabling users and groups ...

Re: [CentOS] Not firewall, but what?
Ok, thanks for ideas - many new things to test. So far no luck. Too bad i don't have first-hand access to any of the client machines who *do* have this problem. Next, I will go and switch the ethernet cable to a different slot on the router - kind of desperate, I know. Some more details: - this web server is a xen virtual guest system, with CentOS 5.4 - the problem surfaced yesterday morning (6th of May), after I had migrated all these web sites from an old Fedora box to this new CentOS system Does the problem affect other xen systems on the same box? I haven't tested this yet (I cannot reproduce the error). You could test yourself if you can see http://62.236.221.71 (the problem system) http://62.236.221.78 (another guest on the same xen host) If someone *cannot* see the 1st one, then it would be interesting to know if (s)he can see the 2nd one or not. - Jussi On 6.5.2010 22.00, Benjamin Franz wrote: > On 05/06/2010 11:42 AM, Ryan Manikowski wrote: >> >> Notice the op posted they get timeouts even when going directly to a >> numerical address (if the apache server is configured to respond to >> *:80 it should at least display something) >> >> Try using telnet from a client machine that can not connect. >> >> e.g. telnet host.name.here 80 >> >> or >> >> telnet xx.xxx.xxx.xxx 80 >> >> Try a few times and see if you're getting a timeout or if it connects >> every time.

(a) You can use "alien" and convert the .deb package to .rpm package and try installing it - caveat not recommended but worth a try (dependencies from the "other" distro can be a nightmare to resolve). (b) build the package from source. many tar ball nowadays come with a .spec file to build the RPM package.

you might just see if you can enable DMA with the hdparm command.
first off...
# hdparm -i /dev/hdb
I only have a IDE cdrom handy on on a centos 5 box (my HD's are all
scsi, hardware raid, or fiberchannel), it displays...

/dev/hda:

DMA modes: sdma0 sdma1 sdma2 mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 *udma2
AdvancedPM=no
* signifies the current active mode
note the * mode. in my case, its udma2 which is fairly fast (I believe
66MB/sec). a modern hard drive should do udma3 or 4 (100 or 133Mhz).
try...
# hdma -Xudma3 /dev/hdb
.dev/hda:
setting xfermode to 100 (UltraDMA mode3)
use at your own risk.

[CentOS] installing gtkmm
Hi, I've been building a gtkmm project on ubuntu and things run smoothly. Now i have to move the project to CentOS 5.4. I set up rpm forge and installed gtkmm. Turns out that the package on rpmforge is too old that my project doesn't compile. I wonder if there is other way to get newer version of gtkmm and all its dependencies instead of manually install them? -best, Ming-ching ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

>Why is my SATA drive showing up under /dev/hdb? That was my hunch:) Config your bios to use AHCI, not compat/ide/or whatever mode it's in now... Watch your fstab/initrd(if custom) if you boot off this disc. If you are using default lvm/initrd, you'll be ok with a change like this. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Try running 'ab' (the apache bench tool - see 'man ab' for how to use it) against your server and see if you can provoke the timeouts. If you can, then you are probably not configured to handle many quick connections and should check (1) httpd.conf to make sure you don't have an excessively low setting for 'MaxClients' or (2) a too low setting for max open filehandles. Look in /etc/security/limits.conf - you should have a line reading something similar to: *- nofile 64000 somewhere in it to raise the max number of open files.

[CentOS] ldap: adding user to multiple groups
Hi all, Not having much luck adding a user to more then 1 group in OpenLDAP thats provided in Centos. Any suggestions to have the outcome of having a user belong to multiple groups? Should I create a new group that has multiple GIDs and assign a user to that new group? If so, how? :) Thanks in advance. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

There is not a single fsync/fsyncdata call in postmark. postmark is completely unsuitable to mimicking mail queues or deliveries to maildirs. I, for one, am glad that Netapp has stopped advertising and have pulled their 'fake' benchmarking utility. It might have been relevant on Linux when it did not have barriers and fsync/fsyncdata had zero guarantees unlike the BSDs and UNIX operating systems. For delivery to maildirs, you want to use fsbench from Bruce Guenter, which does the right thing. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] need document to setup rsync???
What do you want to rsync from where to where?
It is really easy to set up - in fact I just got done writing an
internal wiki page on how to do a simple setup.
The following is what I use for my kickstart servers so the main
server can rsync itself out to slave servers. This sets up
/var/www/html/ks on the slave server as an rsync share that the master
can write to
/etc/rsyncd.secrets
---snip---
kickstart:user
---snip---
This file must be set to permissions 0600
and the main config file
/etc/rsyncd.conf
Here we use a subdirectory of the main default Apache directory which
is /var/www/html
---snip---
# Set this if you want to stop rsync daemon with rc.d scripts
pid file = /var/run/rsyncd.pid
log file = /var/log/rsyncd.log
# Edit this file before running rsync daemon!!
uid = root
gid = root
#use chroot = no
max connections = 3
#syslog facility = local5
[ks]
path = /var/www/html/ks
comment = Kickstart
read only = no
auth users = kickstart
hosts allow = 192.168.0.9
secrets file = /etc/rsyncd.secrets
---snip---
Note in the hosts allow above we put the IP address of the main
kickstart server.
/etc/xinetd.d/rsync
Just update this file and change disable from yes to no
service rsync
{
disable = no
socket_type = stream
wait= no
user= root
server = /usr/bin/rsync
server_args = --daemon
log_on_failure += USERID
}
Now restart xinetd (and ensure it is turned on by default)
Then on the main server I run a script like this :
---snip---
export SLAVES="192.168.0.177"
export USER=kickstart
export RSYNC_PASSWORD=user
for slave in $SLAVES
do
ping -c 3 -w 3 $slave > /dev/null 2>&1
if [ $? -eq 0 ]
then
rsync -avSHP --delete --exclude "local*" --exclude "isos"
/data/ks/
rsync://${slave}/ks/
fi
done
