Adding ClonezillaSE/DRBL to an existing Windows AD environment

Once again, nobody has all the parts and pieces in one location. Verify that the system has two NIC’s. Issue is DRBL myopia Install and update Centos 6.x as normal Install DRBL/Clonezilla per http://winlinuxnet.blogspot.com/2011/07/step-by-step-installing-clonezilla.html STOP dhcpd IMMEDIATELY! After drblpush and dcs, do ‘/opt/drbl/sbin/mknic-nbi –check-server-name n‘ to allow any DHCP to pxeboot clients Create DNS records for […]

Time for time

Time servers send out an epoch pulse with descriptive data. Time clients then transpose that based on locally configured offsets. Windows runs everything through AD, including the time for AD. The official schpiel from Redmond is “Make sure the hardware clock on your AD Forest PDC is set correctly.” Wut? Most important factor is one […]

Windows DAV client note

Windows uses the local appdata temp folder, specifically TfsStore\Tfs_Data for the local service account to do its temp storage of DAV data in transit. Make sure your Windows system drive has enough space plus extra for all anticipated concurrent traffic. C:\Windows\ServiceProfiles\LocalService\AppData\Local\Temp\TfsStore\Tfs_DAV

Slap’d SMB services

Yet again the internets fail. I have simple requirements, and I can’t get simple answers. Manage accounts via LDAP (outside of AD for various reasons) Provide file services against LDAP accounts Set access controls and log everything No one site has all the answers, nor do they hint what parts are missing. This is how […]

Time for time

Windows PC’s in a workgroup can use MS time servers. In an AD environment though they only use the AD server automatically. So the AD server must have legit time. And there’s no obvious way to set time there either. w32tm /config /manualpeerlist:”address.of.ntp” /syncfromflags:manual /reliable:yes /update Props here. Now for your Linux systems you’ll need […]

OpenLDAP 2.4 config

The folks running openldap made some radical changes in how the backend conf is setup starting in 2.3, and now set as default in 2.4. The configuration and longevity of Centos 5 meant that a typical installation didn’t see that change as the Centos 5 packages iirc were still 2.2, and in any case still […]

Java on Linux: OpenJDK does not work for production use, full stop. Least-painful method for Centos 6.x from here: Install system + updates wget rpm bin from Mr. Ellison’s cookie jar Magic sauce is this: /usr/sbin/alternatives –install /usr/bin/java java /usr/java/default/bin/java 20000 You can even do this after a tomcat6 install. Though you might have to […]

WebDav for Windows

Another can’t believe nobody’s had this particular problem before. Anyways, lots of notes consolidated. Windows (XP and newer) insists on Digest Auth for DAV even with SSL. httpd can not do digest if you’re delegating auth to a module, eg mod_ldap. HKLM\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\BasicAuthLevel=1 Windows also caps file size at 50MB. HKLM\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\FileSizeLimitInBytes=0xffffffff Win7 Robocopy adds /MT:xx switch […]

Cause sticky notes don’t work

Cloud backed sticky notes that are taggable and cross platform and AES-256 encrypted. Todo. Meanwhile…

Yes we have no bananas. When queried about recently inexcusable logistics issues, the vendor in question replied with “yes yes they will be there soon”. As a result much drama ensued, and the broader hierarchy has yet to acknowledge culpability in triggering the subsequent fail-cascade. Similarly, a major enterprise in the process of engaging an […]
