Modifying your PHP Handler Configuration via SSH

April 10th, 2010

Your PHP handler and SuExec configuration can be modified in WHM >> Apache Configuration >> PHP and SuExec Configuration, but if you’d like to make your change via SSH, you can use rebuild_phpconf.

Note: with this utility, you can not add new handlers, or enable an alternate PHP version if it’s not installed. You’d need to use EasyApache to enable that change.

What’s my current configuration?
# /usr/local/cpanel/bin/rebuild_phpconf --current
Available handlers: suphp dso cgi none
DEFAULT PHP: 5
PHP4 SAPI: none
PHP5 SAPI: suphp
SUEXEC: enabled

Let’s say I wanted to switch to DSO, keeping PHP4 disabled, and SuExec enabled:
# /usr/local/cpanel/bin/rebuild_phpconf 5 none fcgi 1

For reference, the usage details:
Usage: /usr/local/cpanel/bin/rebuild_phpconf [--dryrun] [--no-restart] [--no-htaccess] [--current|--available]
--dryrun : Only display the changes that would be made
--no-restart : Don't restart Apache after updating the php.conf link
--no-htaccess : Don't update user configurable PHP mime mapping.
--current : Show current settings
--available : Show available handlers and PHP SAPIs
: Version of PHP to set as default handler for .php files
: Type of Apache module to use in serving PHP requests
: enabled, disabled, 1 or 0

Why isn’t this RPM found in yum?

April 10th, 2010

cPanel disables the installation of a number of RPMs, and with good reason. cPanel installs some of these packages via source, and others are modified by cPanel prior to installing them via “upcp”.

This post is here for reference of the default excludes. Excluded packages should not be removed from /etc/yum.conf, as doing so is very likely to break integration with cPanel!

# grep exclude /etc/yum.conf
exclude=apache* bind-chroot courier* dovecot* exim* httpd* mod_ssl* mysql* nsd* perl* php* proftpd* pure-ftpd* ruby* spamassassin* squirrelmail*

Bug in Mailman version 2.1.12.cp3

April 10th, 2010

Error:Bug in Mailman version 2.1.12.cp3

We're sorry, we hit a bug!

Let’s make sure that all other permissions are set properly:

# ./usr/local/cpanel/3rdparty/mailman/bin/check_perms
No problems found

As mailman is working properly on this server, no errors were discovered, but as you’re received the error above, you’ll likely see some errors displayed.

DomainKeys and SPF Record Checking

April 10th, 2010

You probably know that you can configure DomainKeys and SPF records in cPanel >> Email Authentication (if you didn’t, there you go :) ). If you’d like to confirm that your TXT records are working properly, here are some resources for you:

SPF Record Check – via HTTP
PoliteMail’s SPF Check – outputs a brief breakdown of your records details – the IP addresses permitted in the record, the hostname, and the mailserver name. Then outputs the TXT record it queried.

MXToolBox’s SuperTool – Provides SPF checks, among other useful queries.

kitterman.com

SPF Record Check – via email
This is pretty neat – you can send an email to spf-test@openspf.org from the domain you want to test, and it will reject the message, but in that rejection message, you’ll see the results of your test:

spf-test@openspf.org
SMTP error from remote mail server after RCPT TO::
host mailout02.controlledmail.com [72.81.252.18]:
550 5.7.1 : Recipient address rejected:
SPF Tests: Mail-From Result="pass": Mail From="test@cpaneladmins.com" HELO name="server.cpaneladmins.com" HELO Result="none" Remote IP="12.34.56.78"

DomainKeys Record Check

Other Resources:
OpenSPF.org’s Wizard – If you want to configure SPF records manually, go here. Note that you won’t be able to edit the records via cPanel >> Email Authentication later on, though.
