Cpanel SSL 30days warning mails

Your server's SSL certificate for cpanel will expire in less than 30 days

I managed CentOs Server with Cpanel inside.
One day, I receive warning like this:
Your server's SSL certificate for cpanel will expire in less than 30 days. You need to install a new certificate as soon as possible. You can install a new certificate using WHM's "Manage Service SSL Certificates" interface: https://my.server.com:2087/scripts2/manageservicecrts (Main >> Service Configuration >> Manage Service SSL Certificates).

This warning is not indicate a problem in my server. This just a warning that I need to reset SSL certificate on my server. So here the solution to this warning:

• I Login to my server via WHM.
• Then I Go to "Service Configuration" menu and then to "Manage Service SSL Certificates" sub menu.
• I Click "Reset Certificate" button that corresponding to the service which need a new certificate.
• After that the self signed certificate is renewed for one year ahead.

I hope the above explanation will give solution to all of you too. Do you? Send your experience below

HowTo: Install or Upgrade Base OpenSSH for FreeBSD

Different methods to get the base installation of OpenSSH to be upgraded or installed.

### PORTS ###

from ports:

cd /usr/ports/security/openssh-portable
make UPDATE_INTREE_OPENSSH=yes
make install
make clean

### OR ###
for OpenSSL:

cd /usr/ports/security/openssl
make -DOPENSSL_OVERWRITE_BASE install
openssl version

for OpenSSH:

cd /usr/ports/security/openssh-portable
make -DOPENSSH_OVERWRITE_BASE=yes install
sshd -V

### PORTUPGRADE ###

for portinstall or portupgrade, prepare the MAKE_ARGS in /usr/local/etc/pkgtools.conf:

vi /usr/local/etc/pkgtools.conf
Look for an empty MAKE_ARGS and add the following to look like this:

MAKE_ARGS = {
'security/openssl' => 'OPENSSL_OVERWRITE_BASE=yes',
'security/openssh-portable' => 'OPENSSH_OVERWRITE_BASE=yes',
}

using portinstall:

portinstall -rRm "OPENSSH_OVERWRITE_BASE=yes" /usr/ports/security/openssh-portable/

using portupgrade:

portupgrade -rR openssh-portable-overwrite-base

Network Monitoring In Linux

#vnStat

vnStat is a console-based network traffic monitor for Linux and BSD that keeps a log of network traffic for the selected interface(s). It uses the network interface statistics provided by the kernel as information source. This means that vnStat won't actually be sniffing any traffic and also ensures light use of system resources. However, in Linux at least a 2.2 series kernel is required.

This program is open source / GPL'ed and can be installed either as root or as a single user. Better instructions are included in the README. Feel free to send comments by email (remove the spamfilter) or try contacting me from irc (Vergo @ IRCNet).

Best open source webmail clients

There are too many webmail clients are available on web.

Choosing best out of them is quit difficult task for any one.

After exploring tens of webmail clients, I will vote for following webmail client as top 3  webmail clients:

• Roundcube: I would rate it as the best and easy to install. It has rich text editor and clent side filtering support. Also it hase good web interface.

RoundCube

• Zimbra: Not explored much about, but based on futures its quite a popular webmail

Zimbra

• SquirrelMail: Its basic webmail with basic web interface. There is no rich text editor support. There are lot of plugins available for SquirrelMail. 

SquirrelMail

• RainLoop: Recently I seen this webmail client so thought to share. UI is good in RailLoop. I am not tested it but when I walk through installation procedure its looking straight forward and easy.
