Summary: Flow stop in SSH2
Product: Portable OpenSSH
Version: 3.9p1
Platform: ix86
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: sshd
AssignedTo: openssh-bugs@mindrot.org
ReportedBy: shopping@jth.net
I very frequently (i.e. nearly every time) experience the following
on Windows XP SP1 using the POP3 program Agent through SSH2 tunneling via PUTTY
0.56 to fetch mail from a Linux (fedora FC3) box with
OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003
The stream of data stops, but will resume when entering a CR in the PUTTY
window.
Example 1:
