1) Append smtp_generic_maps to Postfix main.cf
[root@server1 ~]# echo ‘smtp_generic_maps = hash:/etc/postfix/generic’ >> /etc/postfix/main.cf

2) Append the necessary outgoing email masks to Postfix address mapping table
<user>@<your_server> <your_email_address>

E.g.
[root@server1 ~]# echo ‘root@server1.mydomain.local admin@mydomain.com’ >> /etc/postfix/generic

3) Create lookup table for Postfix address mapping table
[root@server1 ~]# postmap /etc/postfix/generic

4) Restart Postfix to take effect Postfix main.cf changes
[root@server1 ~]# /etc/init.d/postfix restart

Mutt -

1) ‘set envelope_from=yes‘ in /etc/Muttrc file

2) Create .muttrc file if it’s not alredy created at your user’s home
[sajithr@server1 ~]$ touch ~/.muttrc

3) Add the necessary masks to ~/.muttrc
set from=”<from_email_address>”
set realname=”<username>”

E.g.
[sajithr@server1 ~]$ cat ~/.muttrc
set from=”admin@mydomain.com“
set realname=”foo, server1″

After the upgrade of a specific virtual machine, the first NIC adapter is also changed to use the new VMXNET3 adapter. And finally some of the changes are done to the virtual machine configuration to gain maximum performance (disable VM logging, set unlimited CPU and memory reservations)

Download the script collection from here.

The script collection includes three scripts.

1) vBulkUpgDirector.pl - (Normal Perl script) The main script. This coordinates other sub-scripts, catches the errors from the sub-scripts and throw to STDOUT. The script ’forks’ 10 child processes to do 10 vm upgrades parallelly which greatly reduce the time to finish the full upgrade process.
2) vBulkUpgManager.pl - (vSphere Perl SDK script) A sub-script which creates the list of UUIDs
3) vBulkUpgEngineer.pl - (vSphere Perl SDK script) A sub-script which actually does the job. All upgrade related processes happen here.

vBulkDirector.pl is written to talk to vCenter and make a UUID list for vms under specific folder. Go through the main configuration parameters in vBulkDirector.pl script and make the necessary changes first. And finally run vBulkDirector.pl

############# User configurable variables ####

# vCenter server
my $v_auth_server = ‘<your_vcenter_host>’;
# Username
my $v_auth_username = ‘<vcenter_username>’;
# Password
my $v_auth_passwd = ‘<user_password>’;
# Under which directory the scripts located
my $v_script_base = ‘”<where_are_this_script_located>”‘;
# Under which directory you want to have logs
my $v_log_base = ‘”<where_you_want_to_have_logs>”‘;
# Under which folder your vms located
my $v_manager_args_folder = ‘<vcenter_folder>’;

Acknowledgment: Some of the sub-routines were originally written by William Lam.

2)    Identify the underlying SCSI devices (use multipath -ll to see the underlying devices) and rescan the SCSI devices

[root@zenhat ~]# echo 1 > /sys/block/sds/device/rescan
[root@zenhat ~]# echo 1 > /sys/block/sdr/device/rescan

3)    Drop and add each device path from multipath(no problem, multipath will correctly failover the paths) and resize the related multipath map ( OR reloading the multipathd will do the same job sometimes)

[root@zenhat ~]# multipathd -k
multipathd>
multipathd> del path sds
ok
multipathd> add path sds
ok
multipathd> del path sdr
ok
multipathd> add path sdr
ok
multipathd> resize map dm-23
ok

4)    Check and verify multipath whether it claims the new LUN size

[root@zenhat ~]# multipath -ll
vcb1_100G (3600508b400103e9b0000600001570000) dm-12 HP,HSV200

\_ 1:0:1:9 sds 65:32 [active][ready]
\_ round-robin 0 [prio=10][enabled]
\_ 1:0:0:9 sdr 65:16 [active][ready]

5)    Unmount the partition

[root@zenhat ~]# umount /dev/mapper/test1_10G1

6)    Remove the device’s partition table from device mapper

[root@zenhat ~]# kpartx -d /dev/mapper/test1_10G

7)    Fdisk the device, drop and recreate the partition with desired size. (I’ll also do the 64k block alignment do get the maximum performance)

root@zenhat ~]# fdisk /dev/mapper/test1_10G

The number of cylinders for this disk is set to 1958.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

This will only works under Windows TFTP server as in Unix tftpd, the expected file should be created on the file system before the backup config arrives from Cisco device.

Download the script from this share.

PXE environment is setup under CentOS 5.5-x86_64, with restricted dhcpd (i.e. no free leases), tftp-server and httpd (for hosting installation and some configuration files). Instructions for setting up PXE environment for VMware ESXi 4.1 can be founded here. Here, the typical VMware scripted installation processe has slightly been modified to automatically install multiple hosts simultaneously without any user interaction. The host needs to be *manually* PXE boot. Then it will install OS according to the ks.cfg file and reboot. After the reboot the %firstboot section will execute. During the %firstboot execution, it will look for file, post_install.cfg which includes all the post installation configurations. post_install.cfg requires a file called arp_table to grab the correct IPv4 addresses and hostname(based on vmnic0 MAC address). After executing all post configurations, the host will enter into the maintenance mode and reboots.

According to this setup, all files, ks.cfg, post_install.cfg and arp_table, should be placed under http://<pxe_server>/kickstart directory.

Note: At the time of this writing, in VMware ESXi 4.1 scripted installation, %post section changes are only applied to the pre-boot environment. i.e. the changes you made in %post section will be lost after the first reboot. So %firstboot section is used to make the post installation changes.

It took a very long time to move from Fedora. The main reason why I sticked with Fedora was to align with my RHEL and CentOS servers. But finally I realized the need of a “desktop”. So I decided to go ahead with Ubuntu 9.04 on my Lenovo T61.

Before the installation I read this excellent ThinkWiki article.

Here’s the result.

Hardware

Video – nVIDIA Quadro NVS 140M; OK

Sound; OK

Wireless NIC – Intel; OK

Wired NIC – Intel 1GbE; OK

Bluetooth; OK

Keyboard Shortcuts; Almost OK, even ThinkVantage button! ( except the Atl+F8, Alt+F9, Alt+F12 and Alt+Space bar). To solve Alt+F8 ( Touch-pad on/off) here’s the fix.

Fingure-print; This ThinkWiki solution was helpful to fix the  problem of getting the finger-print reader hot. I had “USB Not Found”, “USB Timeout” and “Reading Error” errors when I was trying to tf-tool –acquire && tf-tool –verify. But after very patient retries, I figured out that swiping a finger “tip” was the trick. If you’ve any problems creating the .bir file, just give a try by swipping a finger “tip” rather than the whole thumb.

Software

Oracle – 11gR1; Here’s the doc. If $DISPLAY environment variable not working, please run xhost local:oracle as privileged user to open ACL for the oracle user to access X and then export DISPLAY=0:0 for the user, oracle.

PL/SQL Developer – v7.1.4; On Wine it’s works pretty muck OK. I un-zipped Oracle basic instant client under ~/.wine/drive_c and specify the oci.dll path on PL/SQL Developer.

Skype – v2.0; OK

VMware Workstation – v6.5.2; OK
