Vi output usually starts in column This happens (every time (?)) for my Linux ISP even for telnetting from the Linux system to itself. I don't think it is a FreeBSD bug :-). It might be a BSD bug, however. Some Linux utilities are ports of BSD utilities and the different environment exposes bugs. E.g., /usr/bin/mail longjmp's out of fgets() when you hit ^C at the prompt, corrupting internal stdio state under Linux. The Linux utilities may be old. My ISP is conservative about upgrading and still has 1992 SLS binaries for things like `cat' that haven't changed significantly. (Unfortunately, `cat' has changed significantly. The old version doesn't follow the Gnu standards for options.) >Yesterday I was playing around with rlogin, and found that if I rlogin >to the Linux machine, there are no problems, and all output starts >in column one as it should.

This happens with both telnet & rlogin. I haven't seen this, but my .profile always sets erase, intr and kill. Bruce
