HJD. -----*----- PPP may be more efficient than SLIP theoretically (I don't know) but as a PPP user I am finding that my PPP-vendor's server is the weak link in the system. I have a hunch that sudden, large variation in the RMS of ping times may be a reasonably good predictor of imminent server-failure but I haven't got around to writing a program to sample the ping times yet. Also I am finding that my current PPP-vendor seems to like to kill my connection if I don't send anything out over the line for more than a few minutes. But I found the Linux end of PPP to be much simpler to set up than I had expected it to be; this fact I attribute to the superb manner in which the PPP software (ppp-2.1.2a.tar.gz) has been configured and documented. IOW, when my PPP-vendor's server is up, it's great! Bill -- Bill Hogan "Show me a wisdom that is greater than kindness."

I've got basically a Slackware 2.0 Linux/X setup, with kernel version 1.1.50. I'm using agetty on VCs 1-6, and X is on VC 7. The man pages for console and tty indicate the /dev/tty? should be mode 622, owned by root.tty, in general. It also makes sense that when a user logs in, they should get ownership of the appropriate ttys. That seems to happen fine for /dev/tty[1-6], but not so for the rest. When I start X, I get ownership of /dev/console, /dev/tty0, and /dev/tty7. When I leave X, I retain ownership. When I log out, I retain ownership. When someone else logs in, they are bummed. In particular, if someone tries to use loadkeys, they find that I own the console and they are not allowed to muck with it. When I say `I', I mean an ordinary user, not root. If another ordinary user starts X, then they get the console, and after exiting they retain ownership. It doesn't look like `startx' or `xinit' are responsible for re- setting ownerships, so I guess it's X. Can anyone suggest what I can do to make things right? Anyone else have this problem? Also I notice that, even for /dev/tty[1-6], when I logout, owner- ship goes back to root.root, not root.tty as the manpage suggests. Yet all the relevant programs (agetty, /bin/login) are owned by root.bin -- which program is responsible here and how can I get it to `do the right thing'??
