The below info is only super quick notes during a clone I ran recently, this is not a complete HOW-TO!! My preference is to use LVM snapshot backups using fsarchiver. I typically have a layout like so: /dev/md0 – /boot /dev/md1 – LVM PV LVM: /dev/vg1/root – root /dev/vg1/home /dev/vg1/tmp […]
This was a tough one to figure out, yet, simple to do once I did it right. I am trying to setup a lab network to do some testing with recovery and migration with older Exchange and Windows servers before we do upgrades to 2012 R2 servers. I am also […]
Error showed: dsi_getsess: Connection refused. Was actually a simple fix. Â (FYI, I am running Netatalk 2.2.4 on FreeBSD/PCBSD 9.1) Open /etc/hosts.allow Add lines for afpd for your network/hosts. Change to match your environment, of course. afpd: [ fe80:ca2a:%nfe0 ] : allow afpd: .1stbyte.lan : allow afpd: 192.168.0.0/24 : allow […]
So with the big outage today, I did some quick looking around. Just wondered if there were any DNS registrars that have decent security practices. It’s tough to find. Not that the attack on GoDaddy was a security breach, it wasn’t. It was a Denial of Service attack, not a […]
I setup a new computer for a client, and Windows 7 would not map the drives in the logon script for the domain account. Ran into this issue, again. Our domain uses a VBScript as our login script, and it appears to run. It runs correctly if started manually, just […]
Well… not much of a guide really. Â Just a very quick how-to on what I did to get Time Machine on my Macbook Pro with OSX Lion 10.7 to save the backup data to my Linux server network share using AFP, rather than SMB (Windows Share), a Time Capsule, or […]
Qwest / Centurylink DSL Web site timeouts, hangups, or failures while running a firewall or router with static IP addresses. Recently I setup the Qwest DSL service in my home. It worked great, but after a couple days I started to get hang ups and timeouts or hangups while browsing […]
I finally did some reading, and found that setting my vfs.zfs.arc_max to about one-half my RAM, minus 512MB, and setting vm.kmem_size to 1.5x my RAM, it would stop giving me the kmem_map panic.
Had a fun time today cleaning off some trojans and rootkits.  On this one client system, while trying to go online, the Internet  turned into the Inertnet! (Hahahha! I love that one!)  As usual, I have lots of ideas why, but no real evidence and clients saying “I don’t know […]
I had a client recently that had their browsers hijacked. Everything they typed in the browser ended up redirecting them to some test_s.php file at “www.fes.skâ€. (Don’t open that, or you might end up with a virus! I just wanted people to find this in case it might help clean […]
I was not able to access a newly joined Windows 7 computer on our domain from our Windows 2000 Server. I just received that error. “Cannot perform the requested operation†Sharing was setup ok, permissions and security set ok, firewall was turned off. I saw an Event ID 2017 on […]
Get the test commands available: get-help test* Should list out the tests available to you. Test overall system health: test-systemhealth Check Outlook Web services: test-outlookwebservices –identity:amailblox@organization.com | fl (note the “fl†at the end, helps reading output, otherwise it will not wrap the lines)
This is just another one of those things that didn’t make any sense and only partially does now. At least NOW I know there is more at play here than the simple solutions in Samba using create mask and create directory mask. In Linux, that’s how I would get around […]
I found some info on Google searches to get Windows 7 to join a Samba domain controller. I have Ubuntu 9.04 Jaunty which runs Samba 3.3.2, which I guess does not work. You need 3.3.4.  Windows 7 needs a registry change: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\LanmanWorkstation\Parameters] “DomainCompatibilityMode”=dword:00000001 “DNSNameResolutionRequired”=dword:00000000 The above need to be added to allow […]
there’s a thing in Ubuntu called Apparmor. Never even heard of this. This is what was keeping the files from being written to by the bind daemon.
Well I just have too much fun with things like this. I don’t know where it came from, but the Blogosphere was a great name people use. I suddenly thought of Nettiverse because I was trying to connect my blog with Facebook and Twitter. I thought they were pieces of […]
This drove me nuts! Why Microsoft had to take something totally simple in Windows 2000 and make it a complicated thing is NOT beyond me! This is MS we’re talking about! Of course it’s not easy with newer versions. Took me a little bit, but here’s the commands I used […]
In Exchange 2007, you have a nice little GUI to set your FQDN on your Send Connector. (Mine is called Outbound, as shown below.) You can see my FQDN, set under the Hub Transport/Send Connectors of the Exchange Management Console. However, if you send mail out to an external address, […]
Well for the larger businesses out there, this may not be a useful tip. But for those of us that support small networks, like less than 50 or even 10 systems, utilizing shares on workstations is sometimes needed. For example, I have servers in most all of my networks, and […]
So you went to add a new address to a user account in Active Directory, and you got an error that this address already exists? Sucks huh? Especially when you don’t know where it could be? Here’s one way to track it down. On your domain root in AD Users […]
