All each successive user needs is the local data space. I suspect 8M + 4M/user is a better estimate for Linux, although I haven't tried it.

I have tried all the combinations of what I thought I used but to no avail. The way I have tried to get out of this mess is by bring up my system in single user mode, which works, and then changing the password.

When I start a new application with color buttons, xpaint for example, parts of the buttons leave residue on the screen. The "residue" "sticks" to the glass, so no matter which part of the virtual desktop I am on, it is still there. The effect is cumulative and won't go away. Is there a root window refresh? or maybe a function to redraw the whole screen?

Every : >thing is fine once I get in, but it is so slooooow to login! Any ideas? : Yeah, have a look at /etc/resolv.conf. There might be a reference to an : unknown name server. Looking up this name server gives a timeout, that's : (perhaps) your delay. Also have a look at /etc/host.conf whether bind : or nis is referenced. If there's no name server (and no nis for that : matter) you might as well delete these key words, leaving only hosts : (for looking in /etc/hosts). We have a similar login problem, especially when connecting to a MUSH port. The connection from a remote host can (sometimes) sit there forever. If, however, from the machine I connect to that port (telnet localhost 7567) the connection from remote becomes instantly connected. We were at first thinking this is a problem with our code, as regular telnet appears to work okay(who knows where that lag comes from? :). But these problems may be related.

See your respective menu : (Control - right button). I saw different xterm versions for XFree86 : (I _really_ wonder why): one which doesn't do logging, and one which does. Mine does allow logging, and it is setuid root. But -- stupid as I am -- I don't see the security hole. Turning on logging, writes to a file called `XtermLog.XXXXX' (the 5 X's are really literally) in my home directory. And if I make `XtermLog.XXXXX' a symbolic link to a file owned by root (/etc/motd for example ;-)), it doesn't write at all. So what?

I am running a multi-line SLIP dialin server. For months we have had problems that sometimes the "sliplogin" program was not getting killed. We finally found that the problem is in the Kernel " close() " function; this function does sometimes *not return*. We have fixed the problem with a patch that re-kills the program after a 15 second timeout, when it is still 'alive'. The problem is definately in the kernel, but we have never found anybody who could do something about it. Our dirty patch keeps our system online, but does not fix the root of the problem.
