You may specify the user shell, +first and maximum user id, group ID in the config file and (unlike WAMPES) +create a file \(lq/etc/ax25/ax25.profile\(rq which will be copied to +~/.profile. +.SH SECURITY +.LP +Auto accounting is a security problem by definition. Unlike WAMPES, which +creates an empty password field, Axspawn adds an \(lqimpossible\(rq ('+') +password to /etc/passwd. Login gets called with the \(lq-f\(rq option, thus +new users have the chance to login without a password. (I guess this won't +work with the shadow password system). +.LP +Of course +.B axspawn +does callsign checking: Only letters and numbers are allowed, the callsign +must be longer than 4 characters and shorter than 6 characters (without +SSID). There must be at least one digit, and max. two digits within the +call. The SSID must be within the range of 0 and 15. Please drop me a note +if you know a valid Amateur Radio callsign that does not fit this pattern +_and_ can be represented correctly in AX.25. +.SH OPTIONS +.TP 5 +.B -w, --wait +Disables the prompting for a password if the password entry in /etc/passwd +is either a \(lq+\(rq or blank. +.SH FILES +.nf +/etc/passwd +.br +/etc/ax25/ax25.profile +.br +/etc/ax25/axspawn.conf +.fi +.SH "SEE ALSO" +.BR axspawn.conf (5), +.BR ax25d (8). +.SH AUTHOR +Joerg Reuter DL1BKE <jreuter@poboxes.com> |
