Thanks very much for input. I did further research, but not working as a result. However, I feel I'm very close.
HERE IS WHAT I FOUND 0: ThinkpadX61's wirless is intel 4965. The driver is SUNWiwk (ifconfig iwk0) 1: http://software.intel.com/en-us/blogs/2008/03/18/opensolaris-im-a-sucker-for-a-good-demo/ --Our OpenSolaris Intel Wireless driver for the 4965 (Centrino Pro) now can do "ad hoc" mode. Here you can associate a group of computers together in a little private LAN, without needing the presence of an internet connection. 2: http://opensolaris.org/os/project/sierra/ --Sierra ? iwk ph1.5 * IWK driver is for Intel 4965 WiFi chipset. Calibration and IBSS(adhoc) functions are added in this version of driver. * iwk Calibration support has been integrated into snv_99, while IBSS support has not been integrated yet. 3: http://blogs.sun.com/judychen/entry/creating_ad_hoc_wireless_connection (this is ath0 not iwk0) # ifconfig ath0 plumb # wificonfig -i ath0 setparam createibss=yes essid=mywifi encryption=wep wepkey1=1234567890 HERE IS WHAT I DID/TRIED my opensolaris version is now snv_100 and updated all packages to the latest on Nov.1 2008 # pkg info SUNWiwk Name: SUNWiwk Summary: Intel(R) PRO/Wireless 4965AGN driver State: Installed Authority: opensolaris.org Version: 0.5.11 Build Release: 5.11 Branch: 0.100 Packaging Date: Sat Oct 25 02:50:05 2008 Size: 583.28 kB FMRI: pkg:/SUNWiwk at 0.5.11,5.11-0.100:20081025T025005Z This driver(default installed @snv_100) is the same version which I could get from http://opensolaris.org/os/project/sierra/ --Sierra ? iwk ph1.5 Also, installed net80211 binary from the above page ~/Desktop/net80211-ph/obj32# cp net80211 /kernel/drv ~/Desktop/net80211-ph/obj64# cp net80211 /kernel/drv/amd64 Reboot System... #wificonfig -i iwk0 setparam createibss=yes essid=mywifi encryption=wep wepkey1=1234567890 wificonfig: failed to set 'createibss' for Operation not supported THAT IS IT According to the information I got, the latest SUNWiwk driver on snv_100 works fine with ad-hoc mode on intel 4965, but turned out it failed. Anyone has any idea? Thanks. -- This message posted from opensolaris.org
