Just to jump in here and bug someone else. I had the same problem, had configured the kernel fo snp, and eventually ran MAKEDEV snp0 per John-David Childs (thanks!). Then I tried: #watch ttyp0 Got a blank screen and exited quickly. (If it means anything I"m running rc5v2 on ttyp0, the joint endeavor to break rsa 56 bit.) And I'm doing this remotely from a (network) telnet session. Now I get this: su-2.00# ls -l /dev/snp* crw------- 1 root wheel 53, 0 Jul 7 13:14 /dev/snp0 su-2.00# who rileyj ttyp0 Jul 6 15:14 (my ip stuff) rileyj ttyp1 Jul 7 12:50 (my ip stuff) su-2.00# watch ttyp0 Fatal: Cannot open snoop device. su-2.00# Any ideas? > From: Wolfgang Helbig <helbig@MX.BA-Stuttgart.De> > Subject: Re: your mail > To: maillist@home.comhelp.com (Mail Lists) > Date: Mon, 7 Jul 1997 09:38:15 +0200 (MET DST) > Cc: freebsd-questions@FreeBSD.ORG > > > > Hi...I'm trying to figure out how to get watch to work....I've read the > > man page, but I get hung up after I run watch ttyx.
