We have found a portability problem in fing.c, which is a "front end" to finger that knows about network connections. I would normally report it directly to the author, cak, but I have been unable to figure out which of the 50 *.purdue.edu machines to use. Anyway, in fing.c, look for the first occurence of strcat. You will find a call of the form write (fd, strcat(user, "\r\n"), strlen(user) + 2); This code seems to assume that arguments are evaluated right to left. I believe that in C, evaluation order is undefined. At any rate, it causes obscure symptoms on a Pyramid. I suggest strcat(user, "\r\n"); write (fd, user, strlen(user)); which works fine on the Pyramid, and would seem to be portable.
