I have done this for 10 characters with no trouble. To go behond 11 you will need to also change a parameter in the file /usr/src/sys/sys/param.h MAXLOGNAME is 12. Beware tho - when I raised this parameter other bad things happened. I fell back to 10 since that was all I needed at the time. I would also worry about some unanticipated weirdness in sendmail if you make it too large. Regards, Mark Hittinger Netcom/Dallas bugs@freebsd.netcom.com
