If you try to expire the tape using the following command, it outputs with error.

To reuse the tape, you need to relabel it. You can find the procedures below.

First get the information about the tape.

Now de-assign id.

source volume pool number information can be obtained from previous command.

Now relabel Media.

If you enter wrong media type, you will not be able to proceed. To find the media type, Go to Media and Device Management > Media > Volume Pool  > Select the volume pool to find the media. Here you can find the “Media type” too.

The above script is to find the number of connections to port 25, If you need to check the corresponding port, you can change it in the awk statement. To find the number of connections to port 80

You can access the queue prompt using the “imsimta” binary. It is present in the Iplanet installation directory.

You will receive the prompt like

To find the summary of the mail in queue, you can enter the verb “summarize” in the prompt

eg:

To check for spam mails in queue, you can use the “top” verb

Here is an example on how to delete the mails having the subject “Delivery Notification Failed”

Another case where the subject line is smaller,  you need to use the following option

The Iplanet message queue is divided into four subqueues,

tcp_local, tcp_imss , tcp_auth, reprocess and process

If lot of messages are accumulating in a particular queue, you can delete them too, this is done using the delete verb

To check the summary,

Check whether inet daemon is running.

ps -ef | grep inetd

Now edit the file /etc/inet/inetd.conf. Find the following lines

# TELNETD - telnet server daemon
telnet  stream  tcp6    nowait  root    /usr/sbin/in.telnetd    in.telnetd

Make sure that “telnet” line is uncommented.

Now open the file /etc/inet/services. Uncomment the line which says telnet

telnet          23/tcp

Now you need to restart the inetd if it was running or you need to start it.

find the process id using

ps -ef |grep inetd

kill -HUP <processid>

to restart the daemon.

If the service was not started initially, start it using the following command

/usr/sbin/inetd -s

check with ps -ef whether the process is running. Now try to connect using telnet and it should work fine.

The telnet root login won’t work. To enable it make the changes given below.

Assign 644 permission to the file /etc/default/login

chmod 644 /etc/default/login

Edit the file to find the line

CONSOLE=/dev/console

Commend the above line. Now the telnet should work fine for root login too. PLEASE NOTE THAT ENABLING ROOT LOGIN IS UNSECURE FOR A PRODUCTION SYSTEM.

By default, the fedora installation won’t allow the X session to listen on TCP. You can confirm this by checking the below command

ps aux |grep -i xorg

The output will be like

=============

root      1263  3.1  1.2  34572 15944 tty1     Ss+  08:14   4:54 /usr/bin/Xorg :0 -nr -verbose -nolisten tcp -auth /var/run/gdm/auth-for-gdm-PYoLoS/database vt1
root     24778  0.0  0.0   4468   756 pts/3    S+   10:47   0:00 grep –color=auto -i xorg

=============

You can find in the options that -nolisten tcp is present. We need to ask the X session to listen via IP. This can be done by adding a directive in the file /etc/gdm/custom.conf

Under the “security” directive add DisallowTcp=false

[security]
DisallowTCP=false

Now logout and login back again. Check ps aux |grep -i xorg again and ensure that now the option -nolisten tcp doesn’t come up.

Now add the IP address of the remote Solaris server to the access list

xhost <IP address of the Solaris server>

Now login to the Solaris server using telnet.. SSH won’t work for X session.

telnet <IP address of the Solaris server>

enter the login credentials. Once you have logged in use the xterm to run any GUI softwares.

xterm

Window should now come up.

I have come across a problem with the LG GX200 set. In fact, it is not a big issue.

Heres the scenario, I have a Reliance sim in Slot 1 and Airtel in the Slot 2. The mobile office(unlimited connectivity) has been activated in the Airtel sim which is slot 2.

The GPRS is working fine in the default browser. However, the Java applications are not able to connect. The network profile is also configured.

Menu > Mystuff > Games & Apps > Network Profile > Sim2 > (Mobile office was activated).

Eventhough you have configured the network profile, the Java applications won’t work. I think the software is checking with the sim in slot 1.

The fix is to interchange the SIMs in the modules. In my case, slot 1 with Airtel and Slot2 with Reliance. I think, the software guys might not have detected this as a bug.

Installation

rm -fv csf.tgz
wget http://www.configserver.com/free/csf.tgz
tar -xzf csf.tgz
cd csf
sh install.sh

After the installation you will need to customize CSF to run on VPS:

edit /etc/sysconfig/iptables and add

-A FORWARD -j ACCEPT -p all -s 0/0 -i venet0
-A FORWARD -j ACCEPT -p all -s 0/0 -o venet0
-A INPUT -i venet0 -j ACCEPT
-A OUTPUT -o venet0 -j ACCEPT

create file /etc/csf/csfpre.sh and enter all the extra rules directly into it prefixed with “iptables” so the contents of that file should look something like:

iptables -A INPUT -i venet0 -j ACCEPT
iptables -A OUTPUT -o venet0 -j ACCEPT
iptables -A FORWARD -j ACCEPT -p all -s 0/0 -i venet0
iptables -A FORWARD -j ACCEPT -p all -s 0/0 -o venet0

edit /etc/csf/csf.conf file and add
and search for

ETH_DEVICE = ""

change to

ETH_DEVICE = "venet+"

Restart

/usr/sbin/csf -r

LOCKOUT ISSUES FOR CSF WHEN INSTALLED IN VPS. or Cannot enter into server after CSF installation on VPS

If the required IP table modules are not properly loaded to the container node, you may lockout yourself after the installation. If you have access to the main Hardware node, you can perform the following to get it up or ask your VPS provider to perform this on the Hardware (main) node.

Before enabling iptables on VPS, it needs to make sure that the iptables modules are enabled on the Hardware Node. In order to enable iptables modules on Hardware Node, edit /etc/sysconfig/iptables-config file on a Virtuozzo hardware node and look for the following parameter value: IPTABLES_MODULES=. Edit it as the following.

IPTABLES_MODULES=”ipt_REJECT ipt_tos ipt_TOS ipt_LOG ip_conntrack ipt_limit ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length ipt_state iptable_nat ip_nat_ftp”

Also edit /etc/sysconfig/vz file on a hardware node and look for the following parameter value: IPTABLES= , change it to the following.

IPTABLES=”ipt_REJECT ipt_tos ipt_TOS ipt_LOG ip_conntrack ipt_limit ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length ipt_state iptable_nat ip_nat_ftp” 

Now your Hardware node is fine. You need to enable the iptable modules to the VPS nodes.
(CID — container ID. You can find the value for each node by using the command vzlist -a)

vzctl stop CID

vzctl set CID --iptables ipt_REJECT --iptables ipt_tos --iptables ipt_TOS --iptables ipt_LOG --iptables ip_conntrack --iptables ipt_limit --iptables ipt_multiport --iptables iptable_filter --iptables iptable_mangle --iptables ipt_TCPMSS --iptables ipt_tcpmss --iptables ipt_ttl --iptables ipt_length  --iptables ipt_state --iptables iptable_nat --iptables ip_nat_ftp --save

vzctl set CID --numiptent 2000 --save

vzctl start CID

Now try entering into your node and restart CSF. It should start working fine.

The usual error which comes up with phpmyadmin. The issue can either be due to the cPanel’s PHP or its session settings. Try the following fix

Open up the file /usr/local/cpanel/3rdparty/etc/phpmyadmin/php.ini

Change the session path to /tmp

From

session.save_handler = sqlite
session.save_path =/var/cpanel/userhomes/cpanelphpmyadmin/sessions

To

session.save_handler = files
session.save_path = /tmp 

Go to WHM > Tweak Settings > “The maximum memory a cPanel process can use before it is killed off (in megabytes). Values less than 128 megabytes can not be specified. A value of “0″ will disable the memory limits.”

Set this to 0 or a higher value..

In the Awstats case, the cPanel processes memory is getting exhausted.

This can be done also by editing the file /var/cpanel/cpanel.config

maxmem=0
/usr/local/cpanel/whostmgr/bin/whostmgr2 --updatetweaksettings

When PHP is compiled as CGI, you won’t be able to provide custom php flags in .htaccess or just simply add a php.ini if your home directory.

To enable a custom php.ini for your domain running PHP as cgi, perform the following steps.

Please note that I am considering that the server has PHP4 and PHP5 where PHP4 is default (dso)-not relevant and PHP5 (cgi)

My username is “presoon” so my home directory will be “/home/presoon” (replace with yours)

create a custom cgi script in your cgi-bin directory.

vi /home/presoon/public_html/cgi-bin/php.cgi

add the following contents.

#!/bin/sh
exec /usr/local/cpanel/cgi-sys/php5 -c /home/presoon/public_html/

You should have the custom php.ini at “/home/presoon/public_html/”

chown presoon.presoon /home/presoon/public_html/cgi-bin/php.cgi
chmod 755 /home/presoon/public_html/cgi-bin/php.cgi

Now to the .htaccess file at “/home/presoon/public_html/”
Add the following

AddHandler application/x-httpd-php5 .php
Action application/x-httpd-php5 /cgi-bin/php.cgi

Please note that AddHandler given above is to change default php to PHP5. If you have only PHP5 which is compiled as CGI, you can remove the directive AddHandler from .htaccess.

Now the values given in your php.ini at /home/presoon/public_html/ should reflect you info page.
