    iSCSI target/client for Linux in 5 whole minutes

    ByEtzion 04/12/2007

    I was playing a bit with iSCSI initiator (client) and decided to see how complicated it is to setup a shared storage (for my purposes) through iSCSI. This proves to be quite easy… On the server: 1. Download iSCSI Enterprise Target from here, or you can install scsi-target-utils from Centos5 repository 2. Compile (if required)…

    RedHat 4 working cluster (on VMware) config

    ByEtzion 11/11/2007

    I have been struggling with RH Cluster 4 with VMware fencing device. This was also a good experiance with qdiskd, the Disk Quorum directive and utilization. I have several conclusions out of this experience. First, the configuration, as is: <?xml version=”1.0″?> <cluster alias=”alpha_cluster” config_version=”17″ name=”alpha_cluster”> <quorumd interval=”1″ label=”Qdisk1″ min_score=”3″ tko=”10″ votes=”3″> <heuristic interval=”2″ program=”ping vm-server…

    A note about VMware-Server machine security

    ByEtzion 10/11/2007

    VMware allow setting a virtual machine as a private machine. By doing so, it actually adds to “/etc/vmware/vm-list-private” an additional comment, stating who is the owner of the machine. For example: cat /etc/vmware/vm-list-private # This file is automatically generated. # Hand-editing this file is not recommended. config “/vmware/Centos4-01/Centos4-01.vmx|root” config “/vmware/Centos4-02/Centos4-02.vmx|user” While it is very effective…

    VMware Perl SDK bug and workaround

    ByEtzion 10/11/2007

    During an attempt to use the VMware Perl SDK, I have encountered the following error: VMControl Panic: SSLLoadSharedLibrary: Failed to load library /usr/bin/libcrypto.so.0.9.7:/usr/bin/libcrypto.so.0.9.7: cannot open shared object file: No such file or directory This is weird, as it was compiled successfully on my system (Centos4), but still… The workaround was to create two symlinks: ln…

    Sony PSP – Connecting Keyboard – Get more out of your PSP

    ByEtzion 01/10/2007

    I wanted to purchase a keyboard for my PSP for a long while. Only several days ago I actually did it. I was surprised at how simple it is to connect and use it. Mind that it: 1. Requires OE firmware (I use 3.03-OE) 2. All is a beta/alpha software, and misbehaves accordingly, on occasions….
