Wifi – Setup Ad-hoc WIFI from terminal in OS X

adhoc-networkmac-osxwifi

Is it possible to create a Ad-hoc Wifi network in OS X using the command line? Without using Apple Script to do it through the UI.

I've used sudo /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -i[<arg>] to do the job. Take a look at /usr/sbin/networksetup to round out the solution.

It should be as easy as simply replacing the word 'localhost' with the IP or DNS address of your 'server' machine. That said you may have firewall rules, web server setup options etc. which could get in the way of this but it's worth trying first of all as it's so easy.

It shouldn't be a problem - by default in an ad-hoc environment where you are not running a DHCP server or setting static ip's the systems should both end up with automatically assigned private ip-addresses in the link-local address range ( 169.254.0.0/16 subnet for ipv4 )and should be able to communicate. If your systems connect to each other at the physical layer but don't end up with ipv4 addresses in this range then one or other of the relevant zero-configuration services are probably disabled.

I'd be surprised if you didn't have to disable the client firewall on the target (Windows Vista) System. This is exactly the sort of casual connectivity that the Windows Firewall is intended to block unless you explicitly tell it not to.

In a Windows environment systems broadcast based NetBIOS name resolution mechanisms will kick in (provided they are enabled and the systems are configured to treat the ad-hoc network as trusted rather than public). I believe MAC OS X also supports NetBIOS name resolution but I don't know if it is enabled by default.

Apple's Bonjour and SSDP\UpNP on Microsoft systems provide more general purpose\robust name resolution services in link-local setups. You can install a Windows Bonjour client to make it easier for the systems to find each other
