Subject: sending SIGCONT to suid root child process Newsgroups: net.bugs.4bsd Distribution: net.unix Has anyone come accross this problem I am experiencing?: I have a process which spawns a child which executes a set uid to root process. The parent wishes to signal the child to tell it when to exit, so following the manual page kill(2) in the 4.2 manual, I try to send SIGCONT. However the child does not receive the signal. I know there are ways round this, like having the parent suid root too, but for various reasons I would like to have it work like it says in the book... (p.s. - an apology - I sent the start of this item last week by mistake!)
