[Bug 1522] New: MaxSessions=0 causes client to hang
https://bugzilla.mindrot.org/show_bug.cgi?id=1522

Summary: MaxSessions=0 causes client to hang
Product: Portable OpenSSH
Version: 5.1p1
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: sshd
AssignedTo: unassigned-bugs@mindrot.org
ReportedBy: imorgan@nas.nasa.gov


When MaxSessions=0 is set in the sshd_config, client connections hang.
Port forwardings requested on the ssh command-line still work, assuming
the server allows them, but the client is unresponsive to any keyborad
input. Neither ~. nor ^C will close the session.

Based on comments from Damien, the solution may be to to replace a call
to channel_free() with chan_mark_dead() in channels.c.
