If you have a large password file then there will be a considerable resource hit whenever you change a passord or add an account. pwd_mkdb will use a lot of vm and a lot of processor. It is very noticeable. Guido wrote some modifications for pwd_mkdb that causes it to support a "-u username" parameter. Rather than rebuild the entire file, this option causes an update of an existing record, or the creation of a new record. I have tested it, and am running it here in production with no problems seen. This eliminates the resource hit, except in the case of a deletion. We rarely delete records so this is not a big deal. Guido has some small adjustments for chpass, passwd, and passwd.local to call pwd_mkdb with the -u. "vipw" is the only fly in the ointment, since you could modify two or more records. Someone might be tempted to "dd" :-) A rebuild of the entire file must be assumed. Regards, Mark Hittinger Internet Manager WinNET Communications, Inc. bugs@win.net
