I think you misunderstood me :) qeth and ctc are the names of the device drivers. For qeth, you'll usually have run-of-the mill tr* or eth* interfaces, except for the special hsi* (HiperSockets, this may be where the mac address is zero) and osn* (special purpose). For eth*, I don't foresee any trouble, the remainder are ignored anyway. ctc and claw should be unproblematic as well, as they use special interface names (as does netiucv). lcs is the only one I'm not 100% sure about. Interfaces will be tr* or eth*, macaddress may be zero for ethernet (I don't quite remember). Were there any problems associated with persistent rules for ccwgroup devices? ------------------------------------------------------------------------- Take Surveys. Earn Cash.
