[Bug 3172] New: Idle connections not closed automatically

Severity: critical

Hello together,
I have set ClientAliveCountMax=1 and ClientAliveInterval=300 and have
expected that any idle SSH connection will be closed automatically
after 5min of inactivity. This is not the case. I have also tried to
disable it by setting ClientAliveCountMax=0 but the behavior is the
same. Any ssh connection remains open forever.
Can you...

[Bug 3362] New: [RFE] Implement a mechanism to disconnect idle users
...ponent: ssh
Assignee: unassigned-bugs at mindrot.org
Reporter: ggasparb at redhat.com
Many security policies have a security requirement related to
disconnect idle users from remote connections. So far, this requirement
has been fulfilled by misusing the ClientAliveInterval and
ClientAliveCountMax options by setting ClientAliveCountMax to zero.
Newer version of openssh dropped completely this undocumented behavior
and currently there is no other alternative to fulfill the requirement.
This RFE is to add such mechanism where idle users are automatically
disconnected from the remote connectio...

Problem with ssh disconnecting
Running CentOS 7 on workstation and having a problem with ssh disconnects. My ssh_config contains:
Host *
TCPKeepAlive yes
ServerAliveInterval 30
ServerAliveCountMax 300
and sshd_config on the server contains:
TCPKeepAlive yes
ClientAliveInterval 60
ClientAliveCountMax 300
Have I missed any setting needed to prevent these random disconnects? I don't think there is anything wrong with the network card, the driver, or the cable, since if I am on a VPN connection via another server, the VPN and any ssh connection stay up indefinitely.
Thanks.

...email to this community; where there is a larger
community.
Some things that we will like to achieve are as follows:
SSH:
disable root (uncomment 'PermitRootLogin' and change to no)
enable 'strictMode'
modify 'MaxAuthTries'
modify 'ClientAliveInterval'
modify 'ClientAliveCountMax'
Gnome:
disable Gnome user list
Console:
Remove reboot, halt poweroff from /etc/security/console.app
Applying security best practises from various compliance perspective,

ssh server hangs the port even if client machine shuts down
Hi,
I have the following problem with ssh, hope someone can help me with it:
I have 2 processes of ssh server on same Linux machine. One of them is
the normal ssh configuration for Linux, the other one starts with a
custom configuration on another port.
>From the client i do a remote port forwarding to the custom ssh
server: ssh -R 1037:localhost:55555.

Openssh connection closes from time to time. why?
...had troubles with ssh open sessions.
I am connecting from a windows machine via putty and then all of a
sudden it saying something about connection closing.
The OpenSSH version is: openssh-server-5.3p1-81.el6.x86_64.rpm
I tired to configure:
tcp_keep_alive
TCPKeepAlive yes
ClientAliveInterval 240
ClientAliveCountMax 50
Each one of them or all together seems to not solve the problem.
It's not iptables issue since it was stopped and disabled.
If someone have an idea of what can be done or checked I will be happy
to hear about it.
For now I have created a custom OpenSSH-6.1p1 RPM just in case it will

ServerAliveCountMax (and Client) waits for TCP timeout before process exit
I am of the opinion that ClientAliveCountMax should really force a
disconnection from the testing side when a ping-pong control packet
retransmission would exceed the max counter.
But it appears to need TCP to timeout to occur from that point, for the
process/tty to close.
For SSH client options:
-o ServerAliveInterval=60
-o Server...

IdleTimeout patch did not get in?
Doing a search in the list archives, I see that in 2001/2002 there was
a patch made available for IdleTimeout keyword, for example:
http://marc.info/?l=openssh-unix-dev&m=99838019319356&w=2
Looks like that patch did not make it in the following versions of
OpenSSH - is there a reason why - any chance of the patch getting
back in?
I do know about ClientInterval, but I think I need

Persistent SSH sessions
...of 1
to 2 minutes while the modem boots.
I have many SSH tunnels and shells active. Due to the default
"TCPKeepAlive On" setting, these sessions are terminated almost
immediately.
I tried the following configuration:
sshd_config on server:
TCPKeepAlive no
ClientAliveInterval 90
ClientAliveCountMax 6
~/.ssh/config:
Host *
Protocol 2
Compression yes
TCPKeepAlive no
ServerAliveInterval 90
ServerAliveCountMax 6
But I guess the ssh client doesn't try to re-establish the session for
the ServerAlive messages to work. The shells remain blocked after the
modem reboots, an...

ssh client does not timeout if the network fails after ssh_connect but before ssh_exchange_identification, even with Alive options set
...alive messages to the server. Disconnect after 90 seconds.
ServerAliveInterval 30
ServerAliveCountMax 3
In /etc/ssh/sshd_config:
# ClientAlive is more flexible and secure than TCPKeepAlive. (ssh2)
# Send an alive messages every 30 seconds, and disconnect after 90 seconds.
ClientAliveInterval 30
ClientAliveCountMax 3
The ssh client kept hanging even after the network was resumed. It finally
timed out after about 2 hours because the tcp_keepalive_time is set as 2
hours in sysctl.
I looked at the ssh code downloaded from your website and found the Alive
options are only used to setup timeout after ssh_session...
