>Number: 581 >Category: bin >Synopsis: iijppp may hang indefinitely >Confidential: no >Severity: serious >Priority: medium >Responsible: freebsd-bugs (FreeBSD bugs mailing list) >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Sun Jul 2 09:30:00 1995 >Originator: J Wunsch >Organization: >Release: FreeBSD 2.2.0-Development i386 >Environment: FreeBSD 2.0.5 or -current >Description: iijppp may hang indefinitely without a chance for the operator to get rid of it: o it refuses to co-operate with a job control shell (it catches sigtstp), so it cannot be brought into background when needed o it doesn't allow to interrupt it by ^C o when in terminal mode, one cannot go back if the modem or other end of connection dropped DTR, since the ppp process sleeps on ttyin (apparently on the outgoing line, not the controlling tty) In all of the above situations, the only chance is to have another terminal/window/whatever handy to clean up. >How-To-Repeat: Start iijppp. Try ^Z. Try ^C. Run the `term' subcommand on a non-existing modem. >Fix: >Audit-Trail: >Unformatted:
