[CentOS-docs] Updating the RAID1 HowTo to CentOS 6
Hi. The following HowTo on the CentOS Wiki: http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1 valid for CentOS 5, has not been updated to CentOS 6, yet. I found it very useful during the glorious CentOS 5 days and now that I've successfully ported my RAID1 experience to CentOS 6, I'd like to share it with the Community. The title of the HowTo is currently: How to install CentOS 5 on a software partitionable RAID1. After my update it will be How to install CentOS 5 6 on a software partitionable RAID1. Could someone, please, give me the rights to edit that Wiki page? My user name is: GianniGiardina Thanks in advance.

Re: [CentOS] DKIM Pass - Fail - Solved !!!
ntpdate should be run just once and then just have ntpd on.. the nptdate should bring the server to the proper time and cause dovecot to fail..you should only need to run it once (assuming the server is left on and not off for long periods). I run ntpd as a daemon, but not ntpdate... you do have to set up ntp as you have done to get in the pools, but leaving ntp on as a daemon should not affect it...at least it does not with mine. Dear BOB. H, Thanks for your response, you are right, it is ntpdate that create the problem after reboot not ntpd. once the time is corrected by ntpdate after that no issues as long as server is up. there are other solution, who wish to run both daemons. bash script can monitor dovecot every 5min through cron. when dovecot will stop due to time shifted error after reboot, script will start it again. and would be fine as long as server does not reboot again.

Does this give you a clue:
sauron.deepsoft.com% cat /etc/udev/rules.d/10-local.rules
#KERNEL=ttyS0, SYMLINK=mouse
#KERNEL=mice, NAME=input/%k,SYMLINK=mouse
KERNEL==ttyS4, SYMLINK=modem
KERNEL==ttyS5, SYMLINK=back, MODE=0666
KERNEL==ttyS7, SYMLINK=front, MODE=0666
#KERNEL==sr[0-9]*, GROUP=disk, MODE=0666
#KERNEL==scd[0-9]*, GROUP=disk, MODE=0666
#KERNEL==hd[a-z], BUS==ide, SYSFS{removable}==1,
PROGRAM==check-cdrom.sh %k DVD, SYMLINK+=dvdrom
KERNEL==sd[a-z]*, BUS==scsi, SYSFS{vendor}==Kingston, NAME=thumb
Things to note: '/dev/ttyUSB0' is probably not a good name (I get away
with ttyS4, ttyS5, and ttyS7, since these are not hotplugable devices
(they are on a 4 port PCI card). Anything subject to hot pluging (like
my Kingston thum drive), should probably be using a NAME or SYMLINK
directive and be testing on something like a SYSFS{vendor} or something.
Each time you plug it in the name could change, depending on what else
is plugged in at the time.
You probably want something like:
KERNEL==ttyUSB*, BUS==usb, SYSFS{vendor}==whatever, MODE=0777,
SYMLINK=USBSerialPort
Put this in /etc/udev/rules.d/10-local.rules
Replace 'whatever' with the vendor name or use SYSFS{idVendor} and the
hex code, possibly also with a SYSFS{idProduct} test as well. You can
find out what works for the SYSFS keys by looking in
/sys/bus/usb/devices/usb*/* -- the keys are the names of the files and
the values to test for are the contents of these 'files'.
TIA

Any security issue respecting access to Webmin is handled simply and efficiently in three steps: 1. Set IPTables, or whatever firewall you employ, to block all access to webmin's listening port (default 1) from addresses outside your local lan or from any but a specific host address. Do this first and reload the firewall rules. 2. Install and immediately configure Webmin to use https only. This can be done from the command line using any convenient editor by editing the following three lines in /etc/webmin/miniserv.conf: keyfile=/etc/webmin/miniserv.pem ssl=1 ssl_redirect=1 3. Create a secure tunnel to an address inside your firewall that is permitted access to webmin using whatever means you find convenient. I use SOCKS via ssh -D 2001 user@host with RSA certs and Firefox configured to use the SOCKS proxy on my local host. VPN or other techniques will work as well, if not better. But SOCKS over ssh works well enough for my purposes. This will get you up and going without ever having to pass credentials to webmin over the wire enclair. Webmin has the virtue of being remarkably easy to setup and simplifies most abuse configuration issues on a wide variety of services. For one, it usually handles which files require which configuration options. It does not, and cannot, cover every eventuality. But, for basic setup and ongoing control of the main system services running on most mainline Linux distros Webmin works most admirably in my experience. It certainly saves me a great deal of time and frustration. I would not give access to Webmin to anyone that did not already have root access to that server. But, if they already have root then I see no reason to make their work any harder than it needsbe. One caution. Webmin is a powerful tool. If you do not know what you are doing then you can hurt yourself very badly with it. On the other hand I have made serious configuration errors with an editor some of which were just spelling mistakes; a problem that Webmin mostly avoids. -- *** E-Mail is NOT a SECURE channel *** James B.

[CentOS] Upgrading PHP and PHP53 on CentOS5 - Progress/Problem w/ Squirrelmail
Greetings In the attempt to upgrade the technology stack on CentOS 5 from stock PHP to PHP53 I have made some progress. Much thanks to all respondents, especially Jesus. One repository that provides a complete set of builds and seems to fulfill both PHP and PHP53 requirements is the IUS one: http://iuscommunity.org/ Repos here: http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/i386/repoview/ One reference to several discussions covering this topic are available here: https://www.centos.org/modules/newbb/viewtopic.php?topic_id=30881 Using the IUS PHP53 rpms allows for the rpm re-installation of drupal6, phpmyadmin, and squirrelmail. However, with Squirrelmail there is one critical issue. Via one of its plugins, Squirellmail provides an html email editor. With the upgrade to PHP53, the editor continues to work. However, the html email that is composed using this functionality is received empty. Reverting back to the original CentOS PHP packages re-enables this functionality. Is there a solution to this issue? Much thanks. One (secondary) thing. In order to support yum updates from the IUS repository, how do I load the appropriate file? Much thanks.

[CentOS] down to the nitty gritty, mysql replication
Almost done with my centos handbook project on my server. Last two things are related, backups. Looking for anyone who feels like chiming in on mysql backups...this is what I am thinking at this point. Mysql backup system for all websites Each website is on a separate server, each running mysql, no site is related to the others. A server will be built (VM) that will host mysql. I believe the way to do this is as follows... 1- make a separate instance of mysql on the backup server equal to the number of websites I am going to backup 2- set up each website's mysql to be a Master 3- set up each instance of mysql on the backup to be a slave to its website Master 4- run them all at the same time, replication from master to slave 5- on the backup / slave mysql instances run logs, back up by day, dump daily I believe, not sure, this will work. Not sure if a better way. The replication allows for a full and almost up to the second copy should a corruption happen on the Master. The daily log files and dumps on the backup server allow for rebuild due to hacker attack. The backup server handling the dumps prevents any issue with the website mysql and the web application. From there, amanda will grab those backup log and dumps to add to each site's file backups. And that is the logic of what I think I can do with this. Trying to back up multiple websites files, logs, and mysql. Amanda will do all but the mysql. sound right? This is the last big step before I start writing the chapters out for the book. Hope to get it done within a month or two after the backup system is done. any thoughts appreciated. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Incomplete host name resolution
Hello
I happen to have two network interfaces on my new, up-to-date, CentOS
6.2, named eth0 and virbr0 (3 of them if I include the lo interface).
However the system APIs like getaddrinfo() only return the address for
the virbr0 interface (which was created by the CentOS installation),
when I would like to have them both.
Even if I give the configured eth0 address explicitly to getnameinfo(),
it can not perform the reverse lookup to my hostname, and returns a
string with the same numeric IP address given as argument. I also can
not get the list of samba name aliases for my host name.
I can happily ping my host from a different computer on the eth0
network, so the nmb service binds on eth0 and works as expected.
I have installed and configured smb, nmb and winbind services, and I
have added 'wins' to /etc/nsswitch.conf, so my hosts line there looks like:
hosts: files wins mdns4_minimal [NOTFOUND=return] dns
Is there something I should do for wins name service to return all IP
addresses ?
Are there some similar settings that I need to do in order to get the
reverse lookup to work ?
For reference here are my system information and application output, as
follows.
Here are my interfaces:

[CentOS] SELinux prevents my PHP script from sending mail
Hello all... I maintain an amateurish email list for my wife's website on my CentOS 6 server. Once-a-month, she sends mail to mylista...@mydomain.com and the /etc/aliases file redirects that to my script: mylistaddr: | /usr/bin/php-cgi /var/www/html/mydomain/email-cgi.php The script, in turn, reads the recipient addresses out of a DB and composes and sends the mails. This all worked great until this month's mailing. Now sendmail just bounces the mail back 554 5.3.0 unknown mailer error 255. When I see programs complaining about unknown conditions, I usually suspect SELinux first, and sure enough... setenforce 0 then everything works like a charm. I wonder what changed between last month and this month? Anyway, I checked the audit.log file and found the relevant AVC denials. I created a local policy (audit2allow) to circumvent the denials, which helpfully prevented the denial messages in audit.log. But the maillist script still fails identically as long as SELinux is enforcing. And now nothing shows up in audit.log. So SELinux is preventing sendmail from calling my maillist script and not reporting the reason. How do I go about figuring out what's broken and how to fix it? -Alan ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Upgrading PHP and PHP53 on CentOS5 - Progress/Problem w/ Squirrelmail
Squirellmail provides an html email editor. With the upgrade to PHP53, the editor continues to work. However, the html email that is composed using this functionality is received empty. Hi Max. Testing squirrelmail with php53 (epel) from CentOS 5.8: I just installed the html editor plugin from squirrelmail (this one from 2005: http://squirrelmail.org/plugin_view.php?id=209), I activated it, however I don't see how I could test it, I don't see the usual html buttons, under options I checked some probable boxes but to no avail. How do you know the plugin is activated? Could you send me a screenshot? It has been a very long day here, tomorrow night I can make some other tests.
