I would very much like this as well, but I'd also like to suggest we pluck a leaf from the SunOS/SYSV/Linux book and take a couple of extra fields as well. I would like to see: ut_pid (pid of session. This is painful to work around not having!) ut_type (some sort of type-of-record code to replace the "magic" characters in some of the username or tty fields.) ut_hostid (normally an in_addr type of entry so that we can always find the originating host without having to bogusly interpret or convert ut_host to/from hostnames and dotted-quad IP addresses.) ut_host (increased to pad out the record size to a convenient power of 2) I don't see a mirror image of the BSDI file format as particularly important, in all my travels, I've never seen an application (read: non-system) binary that uses the utmp file, except on my SVR3 days. I think Garrett expressed a desire to have a 'version' field somewhere. Cheers, -Peter
