I've encountered problems with the virtual console, after killing the first of the two dosemu processes. By chance, I decided to kill the second, instead of the first, when ctrl-alt-pagedown doesn't work. I havn't encountered as many problems with the console after KILLing the second process listed in the ps list. This could be strictly by chance, though. -- Religion: Yes, I believe there is a Church Murphy's Paradox: doing it the hard way is always easier (: Joe Brown :) joe@apache.dtcc.edu ------------------------------ From: freeman@eagle.sangamon.edu (Jay Freeman) Subject: Getting X working...addendum Date: Fri, 20 Aug 1993 19:34:41 GMT Hello again! I think I now have my Xconfig set up properly, as everything seems to take off, screen blanks, anticipation builds etc, then it bombs out with a "PEX" errror, can't locate default font Roman____M, and says it can't open the mouse. I have an ATI Ultra +. Using syssetup -mouse, I selected ATI XL bus mouse. Should I use something different? If you need more info to help, I can mail my Xconfig etc when I get home this evening.

The disk is controlled by an DTC 3270 VL SCSI adapter. When I try to install the SLS-distribution 1.03 on this disk, no SCSI-device is found (the boot-program ob the a1-disk doesn't find any SCSI-hosts and/or devices) What can I do??? please answer directly to my e-mail address zimmer@marvin.or.uni-bonn.de any help would be wonderful regards, Carsten ------------------------------ From: pdcawley@iest.demon.co.uk (Piers Cawley) Subject: Re: Why use shadow? Date: Fri, 20 Aug 1993 19:27:46 +0000 I like the version of passwd that comes in the perl camel book. It traps bad passwords without being prescriptive, and can be customized to take into account local conditions (for example set it up to reject the names of Halls of Residence or whatever.), reading the source it becomes apparent that Larry Wall (or whoever wrote it) has thought *very* carefully about what makes a bad password. -- +--------------------------------------------------------------------+ | Piers Cawley, 2 Widford Park Place, Chelmsford, ESSEX, CM2 8TB. | | pdcawley@iest.demon.co.uk pdcawley@cix.compulink.co.uk | | Once upon a time, and a very good time it was, there lived a . . . | +--------------------------------------------------------------------+ ------------------------------ From: sjm@ss43.icl.co.uk (Simon McKenna) Subject: Re: Why use shadow?

Date: Fri, 20 Aug 1993 17:47:42 GMT I crossposted this to rec.radio.amateur.packet, since there might be some people which know ka9q by heart and might notice at once what I am doing wrong... Now my problem: Somehow I do not succeed with my DOS-ka9q to Linux-SLIP-Link. I have an oldish i286-12 running DOS with ka9q, ip 192.0.2.44 and a nice i386 with Linux 0.99p12 SLIP, (192.0.2.45) and do the following: On DOS: net.exe ip addr 192.0.2.44 attach asy 0x03f8 4 slip s10 2048 1500 4096 38400 192.0.2.44 route add default s10 192.0.2.44 trace s10 111 On Linux: dip -t remote 192.0.2.44 port cua0 speed 38400 mode SLIP route add 192.0.2.44 I could not do a "route add default 192.0.2.44" resulted in a SIOCADDRT: Network is unreachable ping 192.0.2.44 (does not work) ping 192.0.2.45 (does work, its the local host). btw, How can I tell ka9q to dialin so that I have not to disable the getty first, and more important, how do I tell ka9q and linux to communicate at all?

All letters, 52*52=2704. Which implies that an 8-letter password could be checked in under 18 hours on the second machine if the claim is correct, and in 108 hours on the first. I'm probably doing the math wrong :-) but if you use any 8-bit character except NUL (255 possible characters) an 8-bit password would take 103228 years to crack on the first machine. For a 7-bit-character password (again except NUL --- this because C programs don't work well in general with strings containing NUL, so most if not all password-checking programs for *ix can't handle it) it would take less than 391 years. (Someone air-check me on the math: I took the stated "high end" of one hour, divided by 52**6, multiplied by 255**8 for the first case and 127**8 for the second.) This does assume the "best case" for a password, please note. How many people use the full range of a "char" for password characters, including non- printable characters? It also assumes a limit of 8 significant characters in a password, which is common for (non-C2) Unix. ++Brandon -- Brandon S.
