6.3.3. freeSSHd telnet server problem
(BZ#: 3756)
Description: The telnet client on the NM does not work with the freeSSHd telnet server. The login
(username and password) works properly. After the login, no input is accepted and the CLI is frozen.
Suggested Work-Around: Use a different TELNET SERVER product.
Customer Impact: Minimal. Informational only.
Corrective Action: This issue will be addressed in future software upgrades.
6.3.4. SSH session from the NM takes too long to
timeout
(BZ#: 3760)
Description: Open an SSH session from the NM to an SSH server, and then disconnect the SSH
server from the network.
The SSH session times out after 15 minutes. The CLI is frozen until the session times out. The session can
not be closed using Ctrl-C. Finally, after about 15 minutes, the SSH session from the NM times out.
A user who is managing the NM via serial port may lose access to the NM for about 15 minutes.
Suggested Work-Around: Use the SSH escape sequences to close the connection.
Supported escape sequences:
~. - terminate connection
~B - send a BREAK to the remote system
~C - open a command line
~R - Request rekey (SSH protocol 2 only)
~^Z - suspend ssh
~# - list forwarded connections
~? - this message
~~ - send the escape character by typing it twice
(Note that escapes are only recognized immediately after newline.)
Note that if the remote ssh server is stopped and started again, the ssh client session should close quickly.
Customer Impact: Minimal. Informational only.
Corrective Action: None. This is the expected behavior.
