Bug #: 1938
Summary: EscapeChar sometimes don't work when using
ControlMaster
Classification: Unclassified
Product: Portable OpenSSH
Version: 5.8p1
Platform: ix86
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: ssh
AssignedTo: [email protected]
ReportedBy: [email protected]
When my ssh connection hangs (usually after ADSL PPPoE reconnect), I
always was able to kill it using "<Enter>~." combination (EscapeChar is
set to ~, by default).
Few days ago I've added this to my ~/.ssh/config:
ControlMaster auto
ControlPath /tmp/ssh_mux_powerman/%r@%h:%p
ControlPersist 15m
and since that time I no longer able to kill hang ssh connection this
way
(I've to start ssh with "-O exit" from command line for this).
My first thought was EscapeChar doesn't compatible with ControlMaster,
but later I notice "<Enter>~." combination works just fine while ssh
connection is alive, and stop working only after connection hangs.
So, I decide this may be a bug. In any case, it's very annoying side
effect of otherwise cool feature ControlMaster.
