One of my 3b1's 67mb,3M Ram, Combo Card, .5 meg plug-in board, Exp. box, etc has been having a few problems for some time. I have about decided to reload the OS from scratch but would like to try an easier solution if there is one. Number one is IMHO a definite hardware problem, that is that when the box sets for any extended length of time while logged in to an ID and I come in and try to logoff, it hangs on the bright screen just before the 'Welcome' prompt appears. The second is I believe a corrupted file somewhere, that is that when I try to do a shutdown from any ID (except root) I get an error msg and the shutdown does not happen. (I'll post tomorrow with the error if any one needs it, but I forgot it right now). Can anyone help. I hope to be able to buy a new HB for this machine sometime. I really love it and hope it runs forever. Thanks, John O'Brien (johno@swl_386)

It might be something like a memory leak in some process involved with the active logon. How long is "an extended length of time"? What shell is running? Are there any other processes active? Is this under ua or a plain shell login? >prompt appears. The second is I believe a corrupted file somewhere, that is >that when I try to do a shutdown from any ID (except root) I get an error msg >and the shutdown does not happen. (I'll post tomorrow with the error if any Is this shutdown being attempted from ua, or as a direct shell command? Shutdown SHOULD only be usable by root. Ua uses a suid program to get away with this, and is a security hole. If you can't do this from ua, then someone increased the security of your system by turning of the suid bit on the portion of ua which does it. If the machine is not reachable by modem, you might be able to get away with turning on the suid bit on /etc/init (which is linked to /bin/telinit).
