centos enable LVM for root disk

1. do vgchange -a y /dev/vg1/lv_root

this enables you to see the logical volume from the rescue/gparted disk

1. do mkinitrd -f /boot/initrd-2.6.xxxxxx 2.6.xxxxxxx

if resizing another lvm and file system is not an option (time consuming) a temp solution will be

nagios check_snmp does not work but snmpget does

check_snmp of nagios uses version 1 of SNMP automatically, to force version 2c for the devices that do not support it add a -P 2c to the switches.

Also to check what snmpget is executed by the check_snmp simply run it with -v switch

snmpget works but nagios check_snmp does not

run your check_snmp with -v so it displays what exact snmpget it is calling

SIPXECS 404

On SipXecs when you get a 404 not found, it does not only mean the user was not found, it means that the registrations string was not matched, so it is quite possible that the server aliases are not put under the Domain so strings do not match


XXXX@sip1.sip.company.com needs to match
add sip1.sip.company.com under Domain =>Alias

Add functionality to snmpd to report the output of a script

2. Add it to snmpd.conf

cat /etc/snmp/snmpd.conf

....

3. now snmpwalk it

listen to g722 RTP streams in a PCAP file

The easiest way to listen to g722 RTP streams in a pcap file is to

2. Upload the file in http://pcap2wav.xplico.org/ and download the wav files

in linux client do a

echo 1 > /sys/bus/scsi/devices/0\:0\:0\:0/rescan

# replace 0\:0\:0\:0 with your own disk scsi id and then

use vmware converter to create a copy of the virtual machine which needs to be powered ON for the converter to see the actual data, resize the disks also choose advanced thin for the disk type and have fun, remove the old machine later.

vmware converter helper server error

When vmware can not find the vmware helper server for conversion make sure that

1. conveter and esx server and the machine being converted are on the same lan (check the vlan property before converting)

2. the vlan on which the helper and these other machines are does have a DHCP server on, otherwise configure static IP for the helper

automount a specific directory with autofs

this is what we do
first umount your directory then mount the location you want to another directory and later create a symbolic link with the name you need

rmdir /usr/local/apache-tomcat-6.0.26/information-repository

vi /etc/auto/master
/usr/local/mounts /etc/auto.nfs

vi /etc/auto.nfs

mkdir /usr/local/mounts/m_29

ln -s /usr/local/mounts/m_29 /usr/local/apache-tomcat-6.0.26/information-repository

mount with UUID

get a blkid to find the UUID of the device you are after then in /etc/fstab do like this:

linux iptables SNAT

you do not have to have the ip address of a machine behind iptables set on the gateway machine before you can SNAT with the ipaddress of the machine behind the firewall. In other words you can keep your valid ip address on the machine behind the gateway and still ask your gateway to SNAT with that IP.

Visio add text to shape with yellow dot

In detail, it goes something like this:

1. Create or select a shape (duh!)

2. Open the ShapeSheet via Window > Show ShapeSheet

Go to: Insert > Section and check Controls and Text Transform (if it isn’t grayed out)

You should now see both the Controls section and the Text Transform section in the ShapeSheet.

3. In the Text Transform section, set the TxtPin cells as follows:

TxtPinX = Controls.Row_1.X

TxtPinY = Controls.Row_1.Y

4. In the drawing window, reposition the control handle to a suitable default position. The text should follow along!
