https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200445 Bug ID: 200445 Summary: login into system on serial line /dev/cuaU0 hangs if login shell is /bin/sh Product: Base System Version: 11.0-CURRENT Hardware: i386 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: guru@unixarea.de what is not working: - if I login as any other unpriv user (and I created a new one for this) it hangs after presenting the /etc/motd file; it just hangs login: valentin Password: ..... Last login: .... FreeBSD 11.0-CURRENT (GENERIC) #1 r276659M: Tue Apr 28 15:50:23 CEST 2015 Welcome to FreeBSD! (hanging) I figured out what is causing it: the type of the login shell; it works with /bin/csh, it does not work with /bin/sh. When it hangs, if you launch a truss on the hanging process /bin/sh this process resumes normal operation and you can login. I have two more observations on this: - when it hangs in the login shell /bin/sh, a Ctrl-C on the terminal cancels the hang and a new "login:" appears; - regardless of the shell, if one starts the MUA 'mutt' (an alpha-mode MUA) and below this a 'vim' to write the mail, on return from 'vim' to 'mutt' (the vim is already terminated as process) the 'mutt' hangs too and on Ctrl-C it resumes normal operation; -- You are receiving this mail because: You are the assignee for the bug.
