Using virtual serial ports via named pipes in ESX 3.5
Create a named pipe as you typically would as the server on your first VM.
The corresponding entries in the vmx file:
serial0.present = “true”
serial0.yieldOnMsrRead = “true”
serial0.fileType = “pipe”
serial0.fileName = “/vmfs/volumes/472c028b-dd6c1d22-a8f4-001aa0c0b349/Zangief-Fileserver/Zangief-pipe”
serial0.pipe.endPoint = “server”
serial0.tryNoRxLoss = “true”
Create the same named pipe on your second VM, using the same pipe, but connected as a client, opposed to the server.
The corresponding vmx file entries:
serial0.present = “true”
serial0.yieldOnMsrRead = “true”
serial0.fileType = “pipe”
serial0.fileName = “/vmfs/volumes/472c028b-dd6c1d22-a8f4-001aa0c0b349/Zangief-Fileserver/Zangief-pipe”
serial0.pipe.endPoint = “client”
serial0.tryNoRxLoss = “true”
After you power up the VM, you’ll find it strange that the pipe is not visible in the service console.
ls -l /vmfs/volumes/472c028b-dd6c1d22-a8f4-001aa0c0b349/Zangief-Fileserver/Zangief-pipe
ls: /vmfs/volumes/472c028b-dd6c1d22-a8f4-001aa0c0b349/Zangief-Fileserver/Zangief-pipe: No such file or directory
If you connect to it on the second VM however, you’ll see that it works.
FlickrDown is kix azz!
I was tired of downloading pictures one at a time from someone’s flickr page and so I searched the web for a good program to do it. It will download the highest resolution pictures from someone’s photo sets. It works with a proxy server too! Sitesnagger or wget would download way too much stuff! This application is awesome!
Here’s where you can get it:

BASIC dhcp server – piece of cake!
Wanted to set up dhcp so that I had more granular control since my router kept screwing up and giving the same IP to different hosts.
On Ubuntu 6, I just installed it:
apt-get install dhcp3-server
Then edited the /etc/dhcp3/dhcpd.conf (ddns-update-style was initially set to none):
ddns-update-style interim;
option domain-name “shocknetwork.com”;
option domain-name-servers chunli.shocknetwork.com, resolver1.opendns.com;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet 192.168.0.0 netmask 255.255.255.0 {
range 192.168.0.100 192.168.0.200;
option domain-name-servers chunli.shocknetwork.com, resolver1.opendns.com;
option domain-name “shocknetwork.com”;
option routers 192.168.0.1;
option broadcast-address 192.168.0.3;
default-lease-time 600;
max-lease-time 7200;
}

Bind 9 DNS logging of just queries
Recently, set up logging on the DNS server so I can see which hosts clients are resolving. Pretty cool. i commented out a bunch of stuff that I didn’t need.
This is the stuff that goes into the named.conf file or in my case for Ubuntu 6, /etc/bind/named.conf.options
logging {
// category “default” { “debug”; };
// category “general” { “debug”; };
// category “database” { “debug”; };
// category “security” { “debug”; };
// category “config” { “debug”; };
// category “resolver” { “debug”; };
// category “xfer-in” { “debug”; };
// category “xfer-out” { “debug”; };
// category “notify” { “debug”; };
// category “client” { “debug”; };
// category “unmatched” { “debug”; };
// category “network” { “debug”; };
// category “update” { “debug”; };
category “queries” { “debug”; };
// category “dispatch” { “debug”; };
// category “dnssec” { “debug”; };
// category “lame-servers” { “debug”; };
channel “debug” {
file “/tmp/nameddbg” versions 2 size 50m;
print-time yes;
print-category yes;
};

More FUD – MSFT vs. VMware
http://www.forbes.com/2007/12/13/micros … artner=msn
I can’t believe people are writing stuff like this. VMware has a product that’s better in VMware Server and it’s free too!
Read this http://www.infoworld.com/article/07/12/ … iew_1.html and see that you should really be using VMware server which is free and better than HyperV!

Familiar situation. 
Do so:
service mysql stop
wait until MySQL shuts down. Then run
mysqld_safe –skip-grant-tables &
then you will be able to login as root with no password.
mysql -uroot mysql
In MySQL command line prompt issue the following command:
UPDATE user SET password=PASSWORD(“abcd”) WHERE user=”root”;
FLUSH PRIVILEGES;
At this time your root password is reset to “abcd” and MySQL will now
know the privileges and you’ll be able to login with your new password:
mysql -uroot -pabcd mysql

How to Set Up DNS Blacklisting in a Lab Environment for Test
This is a very simple setup for those who have a lab environment where they do not want to be connected to the public Internet while doing the testing.
Some background:
The way dnsbl works is that when a connection is made to your mail server, it will take the client’s IP address, reverse it, append a domain onto it, and do a dns A or TXT record lookup for that name.
For example, if a spammer’s IP is 10.4.17.108, and you are using spam.list.com as your dnsbl site, your MTA will do a query for 108.17.4.10.spam.list.com. If the query returns positive, it means that the IP address is listed in the blackhole list and that mail should be rejected.
So the first thing you will need to do is set up a simple dns server. You can find out how to do that by consulting the DNS & Bind book or http://docs.sun.com/db/doc/816-7511 or various other sources.
Then, you need to set up a zone. Here's a sample: # cat /var/named/spam.list.com $TTL 86400 @ 1D IN SOA @ root ( 42 ; serial 3H ; refresh 15M ; retry 1W ; expiry 1D ) ; minimum NS localhost. A 10.4.16.11
108.17.4.10 IN A 127.0.0.2 108.17.4.10 IN TXT "10.4.17.108 is listed in spam.list.com"
With this in tact, all you need to do is set up your MTA to use spam.list.com for dnsbl calls.
license problem…not enough licenses, but 0 of 6 are used
LMtools seems to check out the licenses according to their logs, but they check back in immediately. Interesting huh? We tried changing the file different ways – it was so weird. Finally, we had someone in support use the license checker tool that they have and they found that we mixed up the hosted licenses w/ the server based licenses – doh! … so we just separated them and created new files and it was all set.
It turns out that the website when generating licenses can generate host based licenses instead of server based licenses. You can tell the difference by seeing:
VENDOR_STRING=licenseType=Host
opposed to:
VENDOR_STRING=licenseType=Server
