Hi! 2.1.0R and, AFAIK, -current slip implementation buggy. Slip discipline ioctl SLIOCSUNIT not work properly. Code from 2.1.0R: (file /sys/net/if_sl.c, lines 371-373) case SLIOCSUNIT: sc->sc_if.if_unit = *(u_int *)data; break; This code is dangerous. This code change unit number of current slip interface. There absolutely no warranty, but if you running slattach -S 1 you may have two or more interfaces named sl1 in system. Some times this hangs all net-related activity, some times not. Any suggestions? Do not respond with 'not use slattach -S' please, fixed unit feature in slip implementation still important for me. -- Yura
