I would be willing to modify the code for /usr/bin/login if it was generally wanted.... I think some thing like this would work... if the user is logged in(ie: wtmp entry exists) refuse entry with some message else let user in.... This would imply having a file that specifies who is restricted to a single login... 'login' can read this file and if the user calling has an entry in this file, only let them in 1 time... It could be further improved to also specify how many concurrent times a user is allowed to call in... eg: peter:1 joe:3 tammy:1 This would allow peter and tammy to be logged in only once, but, joe could be logged in 3 times... All other users will be unrestricted. Please send comments to jerry@kcis.com I am changing jobs this weekend... KCIS.COM is at home... Jerry Kendall jerry@kcis.com
