For years, weâ€™ve had issues with the fact that there is no good built-in auto-archive feature for Entourage. This has led to many an Exchange environment getting out of control with a lot of Mac clients. To get around this issue, check out Entourage Email Archive X 3.4.0. Itâ€™s a utility for archiving emails and/or attachments for Entourage in Mac OS X. EEAX 3.x works on OS X 10.4.x (Tiger) with Microsoft Entourage 2004. You can Download latest EEAX 3.4.0 from:

So you just installed that new Xserve and you are starting to notice that the AppleFileServer is spiking when your users are searching the AFP volume for some media. To fix, first, backup /etc/rc.server (just in case).
Then change this line:
sysctl -w kern.maxnbuf=90000
Replace the 9 with a 2 and then save the file and then reboot.

One of the biggest issues that a number of large environments have is controlling what client systems are able to see on a network. In these types of environments, limiting the number of Windows file servers that show up can be a show stopper. So Apple has given us an option in the com.apple.smb.server.plist file for RegisterWINSName. By default it isn’t there, but when you use the following command and then restart smb it will suppress your system from the list of servers:
defaults write /Library/Preferences/SystemConfiguration/com.apple.smb.server RegisterWINSName -bool false
You can also use com.apple.smb.server to change the NetBIOS name and server description.

No one ever got fired for buying Cisco. But, I recently saw a shop where they went from Cisco to Enterasys (thanks for showing off your backbone Todd). I must say that I really liked the Enterasys switches. I looked them up and they are about 1/2 the cost of Cisco. They have great tech support and are very easy to configure, even though it’s a command line interface. The only complaint I have about them is the web interface is good for reviewing your setup but inadequate for configuration – but is good for looking at the switch configs. Maybe in time this will mature… I don’t know if they can go to the 10,000+ environments though… Oh, and it required zero config to do link aggregation, which was weird – but cool…
Now, I have really been liking what Foundry is doing with their switches.
And Juniper. If you play your cards right you can even get free training with Juniper, which is pretty cool – and sometimes they give hard core sweetheart deals to larger shops that are switching over to their platform from Cisco.
Of course there are hundreds of other switch manufacturers. The only other ones I’ve seen in really large install bases are HP (which I hear mixed reviews on from Mac guys) and Extreme Networks (again mixed reviews for Mac) and some Allied Telesys Switch Blades (great review but only seen them once – 4000 series blades – with fiber to ring and ethernet to classrooms in the same chassis – it stuck out to me ’cause we used to sell a lot of allied switches and I didn’t know they made blades yet).

Having lived in LA for a decade every time I go back I try and hit at least one of a few different restaurants. The first is BOA, for the best steaks in LA. The second is the Pig on La Brea. The third is right up the road, a little hot dog stand called Pink’s (yes, I said hot dog). And finally, of course, In-n-Out, where you have to order up a “four by four animal style” at least once in your life…

Kerio has a variety of features available for mitigating the evil spam gremlins. These include:
1 – SpamAssassin – Open Source spam filter
2 – Directory Harvest Attack Protection – track email coming in for non-existent users and limit the number allowed per host
3 – Policies – tag emails with X-Spam headers, then use local policies, etc. Also write custom filters that identify certain keywords as spam
4 – RBL – A standard with mail servers, Realtime BlackList servers mark common spammers or hosts that do not meet a minimum criteria for being acceptable mail servers
5 – SPF – Rely on srv reccords from domains to specify what IPs are allowed to send mail as a domain
6 – Domain Name Verification – Seems simple enough, don’t accept mail if the domain doesn’t exist
7 – Connection throttling – Don’t allow more than a certain number of sockets to be opened from a given host
8 – SMTP whitelist and blacklist – always accept or always deny mail from a given host that can be defined in the Kerio Admin
9 – Microsoft Caller ID: http://download.microsoft.com/download/2/e/2/2e2850b8-2747-4394-a5a9-d06b5b9b1a4c/callerid_email.pdf
10 – Spam Repellent – delay the SMTP handshake process to deter spammers

You can use the pslist command to view a detailed listing of all ProcessIDs in Windows. You can then use pskill to kill a PID, or pssuspend to suspend it or psservice to list PIDs that are services. No killall tho, like in Mac OS X…
