sernet.de maintain the latest Samba releases in a yum repository, allowing for an easy and painless install or upgrade of Samba on your yum based Linux distribution.
To install the latest available Samba execute the following commands at the shell:
# cd /etc/yum.repos.d # wget http://ftp.sernet.de/pub/samba/experimental/centos/5/sernet-samba.repo # yum install samba
To upgrade an existing Samba install:
# cd /etc/yum.repos.d # wget http://ftp.sernet.de/pub/samba/experimental/centos/5/sernet-samba.repo ## Note: edit sernet-samba.repo and add the line "gpgcheck=false" otherwise ## it will not install as it is not signed
# yum update samba
Note: These steps will install the very latest build available at sernet.de.
If you require a less bleeding edge version of Samba, use the "tested" repo. This can be found at the following URL: http://ftp.sernet.de/pub/samba/tested/rhel/5
This is a good primer for getting familiar with using Infiniband with Redhat/Centos Linux.
http://people.redhat.com/dledford/infiniband_get_started.html
Getting Started with InfiniBand
The first step to using a new infiniband based network is to get the right packages installed. These are the infiniband related packages we ship and what they are there for (Note, the Fedora packages have not all been built or pushed to the repos yet, so their mention here is as a "Coming soon" variety, not an already done variety):
VMware products, such as ESX, Workstation, Server, and Fusion, come with a built-in VNC server to access guests.
This allows you to connect to the guest without having a VNC server installed in the guest - useful if a server doesn't exist for the guest or if you need access some time when a server would not work (say during the boot process). It's also good in conjunction with Headless Mode.
The VNC server is set up on a per-VM basis, and is disabled by default. To enable it, add the following lines to the .vmx:
RemoteDisplay.vnc.enabled = "TRUE" RemoteDisplay.vnc.port = "5901"
You can set a password with RemoteDisplay.vnc.key; details for how to calculate the obfuscated value given a plaintext password are in Compute hashed password for use with RemoteDisplay.vnc.key.
If you want more than one VM set up in this manner, make sure they have unique port numbers. To connect, use a VNC client pointing at host-ip-address:port. If you connect from a different computer, you may have to open a hole in the OS X firewall. If you use Leopard's Screen Sharing.app on the same computer as Fusion, don't use port 5900 since Screen Sharing refuses to connect to that.
The goal of the SCPlugin project is to integrate Subversion into the Mac OS X Finder.

If when your attempt to create device meta-data fails this is drbd preventing you from corrupting a file system present on the target partition.
$ drbdadm create-md drbd0
v08 Magic number not found
md_offset 30005817344
al_offset 30005784576
bm_offset 30004867072
Found ext2 filesystem which uses 190804004 kB
current configuration leaves usable 29301628 kB
Device size would be truncated, which
would corrupt data and result in
'access beyond end of device' errors.
You need to either
* use external meta data (recommended)
* shrink that filesystem first
* zero out the device (destroy the filesystem)
Operation refused.
Command 'drbdmeta /dev/drbd0 v08 /dev/sda4 internal create-md' terminated with exit code 40
drbdadm aborting
Once you have confirmed that the file system present on the target partition is no longer required at the prompt type the following:
Replace /dev/sdaX with the block device you are targeting.
dd if=/dev/zero of=/dev/sdaX bs=1M count=128
Once this has completed the drbdadm create-md drbd0 command will complete with a "success."

Some options of hdparm are dangerous and are generally listed as such in the man page.
Hdparm is available from SourceForge and there is even a version for Windows.
MQCURMSGS()
Syntax
MQCURMSGS( <expN> )Description
The MQCURMSGS() function returns the current number of unread messages in the queue specified by <expN>Example
mqdes=mqopen("/myqueue")
if (mqdes < 0)
messagebox(strerror()+",errno="+alltrim(str(error())))
return
endif
do while (mqcurmsgs(mqdes) > 0)
mstr=mqreceive(mqdes)
if (empty(mstr))
messagebox(strerror()+",errno="+alltrim(str(error())))
return
endif
messagebox(mstr)
end do
mqclose(mqdes)
SET DATADIR TO [ <directory> ]This command is used to specify a directory where database tables, memos, indexes, and dictionary files are located. When a table is being opened this directory is searched first before the current directory and the file search path to locate the table and its associated files. This allows the database tables to be relocated to a different file system without the need to change an existing application.
