swappiness

This control is used to define how aggressive the kernel will swap
memory pages.  Higher values will increase aggressiveness, lower values
decrease the amount of swap.  A value of 0 instructs the kernel not to
initiate swap until the amount of free and file-backed pages is less
than the high water mark in a zone.

The default value is 60.

Subject:    Coping with screen session and ssh-agent session
Date:   Wed, 17 Oct 2012 18:22:30 +0400
This is well known problem that SSH client cannot connect to SSH-AGENT from
SCREEN session. I will briefly refresh your memory on it. OpenSSH uses
SSH_AGENT_SOCKET environment variable to connect SSH client and agent to get
authentication data. The problem is, that SSH_AGENT_SOCKET is different each
time you connect to host. But SCREEN session retains old value
from the time session was first created. As a result SSH client inside SCREEN
cannot use authentication keys from SSH-AGENT and asks for password.

There are already number of scripted solutions for this problem, that exist on
the net. But none of what I found is fully working. I will skip delving into
deficiencies of their implementations, but will try to deduce universal way
of what should be done for coping with this problem.

First, we need shell to be able to update SSH_AGENT_SOCKET before each command
it executes. For example, in BASH it can be done by 'trap ... DEBUG'.

Then, we need actual SSH_AGENT_SOCKET value for current running SCREEN
session. And this is hardest and in fact impossible part to find it at
runtime. Of course, we could lend to the method of leaving some traces upon
SSH connection like do all the existing examples I've seen. But this, as was
said, lacks universality and leads to deficiency of racing condition.

What should we do to properly find SSH_AGENT_SOCKET, is to trace the path from
the point of running shell inside SCREEN session to SSH connection that uses
this session. And here what I found about what we can do and what we cannot
do. The final goal is to find PID of SSH client. By knowing that PID we can
easily find socket in /tmp/ssh-*$PID/agent.$PID and that will be the value for
SSH_AGENT_SOCKET. To find PID of SSH we need to know PID of SCREEN client
(i.e. 'screen -r' command). By knowning PID of SCREEN client we can easily
find PID of SSH: walk through /proc filesystem.

And what I could not find is how to find out PID of SCREEN client by PID
of SCREEN daemon. The both are connected to SCREEN socket, but there is no
permission to find all processes opening this socket. There is no commands
inside SCREEN to find it. There is interactive command 'displays' that can be
of some help: at least it displays used PTS, but there is no ability to run
it in non-interactive way. Ideally, 'screen -list' should print instead of
just '(Attached)' something like '(Attached to PID)'. And that would be
enough to satisfy my needs.
