Hello, I just found out if I use system default environment, every time I invoke rm(1) or ls(1) for simple ops like rm -rf *.o or ls *.o, I get a core dump. What I did was simple, I just login without .cshrc and .login and I can get core dumps always. I played the same on my SUN SPARC 1+ running SUNOS 4.1.1, no problems. I need to do so to enable the dumped emacs containing just system defaults, not my personal environment. Otherwise users would get getwd(2) error. I use csh, RS6000 320, 16Megs ram, and 64Megs swap. 2nd question: we network all our workstations, including 12 DECstation 3100s 54 SUN SPARCstations, one DEC 5500 and 12 IBM/RS6000s together, we run yp. OK. console login/rlogin/telnet/dial in are all very responsive on any machine other than RS6000s. Which usually takes more than one minute before the password prompt shows up. Due to this problem, users stay away from RS6000s. We have been unable to determine the cause. Could someone suggest certain fixes? So far, we have been unable to get even one successful dial up login on RS6000s. Thanks in advance to any help, please email. I will summarize if there is enough interest.

Do you perchance have a lot of users in your /etc/passwd file? If so, look at the mkpasswd command, it can create a hashed version of your password file that is much faster to search. - Frank Feuerbacher Disclaimer: I speak only for me! And I don't even do a good job of that!
