Usertty sending messages to all user and without login also
Hello everybuddy, I am using syslog-ng and used usertty in destination. I am using a user 'test' as destination. But other users can also see the message on their console e.g root and other users. Please help as this is creating a problem and NG not working as desired. OS: Solaris 10 Anurag

It does work for me. Can you show us the relevant portions of your configuration file? I tried with this: source local { sun-streams("/dev/log" door("/etc/.syslog_door")); internal(); }; destination all { file("/var/log/messages"); }; log { source(local); destination(all); }; destination all_users { usertty("bazsi"); }; filter alert_emerg { level(err..emerg); }; log { source(local); filter(alert_emerg); destination(all_users); }; It correctly printed err..emerg messages on my tty, and not on others. The relevant portion of the code is here: #if HAVE_MODERN_UTMP if (ut->ut_type == USER_PROCESS && ((self->username->len == 1 && self->username->str[0] == '*') || (self->username->len <= sizeof(ut->ut_user) && memcmp(self->username->str, ut->ut_user, self->username->len) == 0))) #else if ((self->username->len == 1 && self->username->str[0] == '*') || (self->username->len <= sizeof(ut->ut_name) && memcmp(self->username->str, ut->ut_name, self->username->len) == 0)) #endif I don't see how this condition could match for everyone. Even if the wtmp format is different and ut->ut_name would contain a bogus value, the expected breakage would be to not display anywhere, not to display everywhere. -- Bazsi
