By default, my mail server (Snow Leopard) contains an entry to only accept SMTP relays from 127.0.0.0/8. However, when I attempt to check the option and save, the computer unchecks it. When I change the IP address to just 127.0.0.0, I don’t experience the unchecking problem. There are two possible solutions: either do you know what is causing the unchecking problem (or which configuration file should I edit to manually do this?), or is it [...]

I’ve installed nginx server on my Mac from MacPorts: sudo port install nginx. Then I followed the recommendation from the port installation console and created the launchd startup item for nginx, then started the server. It works fine (after I renamed nginx.conf.example to nginx.conf and renamed mime.types.example to mime.types), but I couldn’t stop it… I tried sudo nginx -s stop – this doesn’t stop the server, I can still see “Welcome to nginx!” page in [...]

Is it possible for MacOS X (current version or in any previous one) to easily force DHCP client to send to DHCP server, at the beggining of the conversation – in DHCPDISCOVER packet – option “Vendor Class Identifier” (60) set to some value? I know that I can install i.e. ISC DHCP client through pkgsrc which supports VCI, but I’m looking for something native. Thank you in advance for information. Asked by plluksie This rather [...]

SOLVED: The issue is with the hamachi client, hamachi is hi-jacking all of the 5.0.0.0/8 address block http://en.wikipedia.org/wiki/Hamachi_(software)#Criticism http://b.logme.in/2012/11/07/changes-to-hamachi-on-november-19th/ The fix on Mac LogMeIn Hamachi > Preferences > Settings > Advanced > Peer Connections > IP protocol mode > IPv6 only (default is both) If you can only connect to some of your network over IPv4 this ‘fix’ will NOT work for you —– A few weeks ago I started using a service – https://semaphoreapp.com [...]

I have a Meraki wifi network that’s authenticating via RADIUS to an Active Directory. Users log in with their AD username and password via WPA2. That all works. However, when a user changes their AD password (due to expiration, forgotten password, whatever), their Mac doesn’t prompt for a new password; instead, it just can’t connect to the wifi. To fix this we have to go into Network Preferences -> Advanced -> Wifi -> Preferred Networks, [...]

Is there any way to install Ubuntu’s truncate command to Mac OS X 10.7 in order to use the command in Terminal shell? Asked by Shivan Raptor This shouldn’t really be in Server Fault, probably Super User or Ask Different, but you can install a lot of binaries by using homebrew, found here: http://mxcl.github.com/homebrew/ Firstly you’ll need to install command line tools for Xcode, which will probably require you to purchase it if you havn’t [...]

we recently added a MacPro with eight (yes 8) monitors on it. We have various tools for monitoring our website (Chartbeat, Nagios, internal statistics, Jenkins, Smartfox, etc.) and they are currently free-flowing in various browser windows on the various screens. I’d like a better way to organize them into a more fixed system so (a) we can’t just accidentally close out of a window (b) some automatically refresh (currently done through browser plugins) etc. Any [...]
