1) Have you ever been annoyed that, when unpacking a "tape archive" (tar-file) -- if it includes subdirectories, it may seem impossible for the ordinary user to unpack because the files and subdirectories retain their original ownership. I learn in another newsgroup about the sometimes undocumented "o" keyletter of "tar". > use tar xof file.tar > the o keyletter makes you owner of all files you grabbed off the > archive. Otherwise tar tries to reinstate the original > owner/group (using the number,not the name), and that may not be > you. After it grabbed it, changed the owner to the original, it > tries to re-set the time, and can't since it's not your file > anymore. Works for me. I use the 3.5 release of the Development Set. 2) Have you ever tried to set up UUCP via direct line to an intermediate host which is networked to your target UUCP-partner? I have my 3b1 (sphere) in my office, serial cabled to my Sun SLC (zeta), and I wanted UUCP with one of our Sun SPARCStation 1+, (alpha). My first attempt was using "rlogin" in sphere's chat script to reach alpha. But it failed, because (I think), the rlogin connection didn't pass 8-bit bytes. That's why I post this, because it is one step away from the trivial solution, so there may be some who have tried this and given up. Maybe not. I *do* like to see myself type, though. Works for me. I use HDB as found in archives at osu-cis (cheops.cis.ohio-state.edu): chat script on sphere (one line): alpha Any Direct 9600 none "" \d\r ogin:--ogin: Usphere- assword: <secret> $ rsh\s-l\sUsphere;\sexit relevant /etc/passwd lines: Usphere:M1xXsGIjHsdoF:155:8:uucp:/home/alpha/Usphere:/usr/lib/uucp/uucico Usphere-:M1xXsGIjHsdoF:155:8:uucp:/home/alpha/Usphere: and, Usphere@alpha trusts (no password) Usphere-@zeta because a file /home/alpha/Usphere/.rhosts contains the entry zeta.ee.ufl.edu Usphere- Best regards, ruck. -- John R Ruckstuhl, Jr ruck@alpha.ee.ufl.edu Dept of Electrical Engineering ruck@cis.ufl.edu, uflorida!ruck University of Florida

With regard to 2) - UUCP over a network via an intermediate system with a modem. I've done this sort of thing to run SLIP when our dialups are into machines which don't support it. You can get an 8 bit clean connection by rlogin HOST -8 -e which implies: 8 bit connection no escape character -- Scott S. Bertilson ...ssb@quest.UUCP scott@geom.umn.edu
