Node.js redis over SSL Connection Examples

var redis = require('redis');

var tls = require('tls');

var fs = require('fs');

var ssl = {

key: fs.readFileSync("private.key",encoding='ascii'),

cert: fs.readFileSync("user.crt",encoding='ascii'),

ca: [ fs.readFileSync("ca.pem",encoding='ascii') ],

rejectUnauthorized: false

};

var options = {

tls: ssl,

password:'xxxxxx'

};

var client = redis.createClient([the redis port], '[The redis url]', options);

try {

client.on('connect', function() {

console.log('Connected to Redis');

});

}

catch (e) {

console.log('1' + e)

}

console.log('here')

try{

client.set("foo", "bar", redis.print);

}

catch (e){

console.log('2' + e)

}

try{

client.get("foo", function (err, reply) {

if (err) throw err;

console.log(reply.toString());

});}

catch (e) {

console.log('3' + e)

}

try{

client.on('reconnecting', function() {

console.log('Connected to Redis');

});

}

catch (e) {

The problem is Windows Defender , after disabling "check apps and file" Chrome canary is started.

But i guess there is more Serious problem , probably malware.

Starting up mlog2waffle in "batch" mode, using config file /etc/mlog2waffle.conf Error in HTTP connection: 403 Forbidden

The problem is authentication.

Reduce TIME_WAIT socket connections

Original Post:
http://www.linuxbrigade.com/reduce-time_wait-socket-connections/

Some time in your life you’ll run across an Apache server that always has tons of TIME_WAIT connections just seeming to hang out. While these don’t take up as many resources as an ESTABLISHED connection, why keep them around so long? This short article will show you how to identify how many you have, and how to tell your server to reduce them, reuse and recycle them (see, recycling IS a good thing).

First, SSH into your server and become root.

Next, let’s see how many TIME_WAITs you have hanging out:

 

1	netstat -nat | awk '{print $6}' | sort | uniq -c | sort -n

You should see something like:

 

1 2 3 4 5 6 7 8 9 10

1 established)       1 Foreign       3 FIN_WAIT2       5 LAST_ACK       6 CLOSING       9 SYN_RECV      10 ESTABLISHED      22 FIN_WAIT1      26 LISTEN     466 TIME_WAIT

So – let’s get that number smaller.

See what your current values are in these files by catting them to the screen:

 

1 2 3

cat /proc/sys/net/ipv4/tcp_fin_timeout cat /proc/sys/net/ipv4/tcp_tw_recycle cat /proc/sys/net/ipv4/tcp_tw_reuse

If you have default settings, you’ll probably see values of 60, 0 and 0. Let’s change those values to 30, 1, 1.

 

1 2 3

echo 30 > /proc/sys/net/ipv4/tcp_fin_timeout echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse

Now, let’s make the change persistent by adding them to the sysctl.conf file. First however, let’s make sure there aren’t any entries in there yet for these settings.. cat the file and grep for the changes we’re about to make:

 

1 2 3

cat /etc/sysctl.conf |grep "net.ipv4.tcp_fin_timeout" cat /etc/sysctl.conf |grep "net.ipv4.tcp_tw_recycle" cat /etc/sysctl.conf |grep "net.ipv4.tcp_tw_reuse"

Make notes of what your settings are if you had any results..

Now, edit the /etc/sysctl.conf with your favorite editor and add these lines to the end of it (or edit the values you have in yours if they exist already):

 

1 2 3 4 5 6

# Decrease TIME_WAIT seconds net.ipv4.tcp_fin_timeout = 30   # Recycle and Reuse TIME_WAIT sockets faster net.ipv4.tcp_tw_recycle = 1 net.ipv4.tcp_tw_reuse = 1

Now, let’s rerun that command from before and see where your TIME_WAITs are at:

 

1	netstat -nat | awk '{print $6}' | sort | uniq -c | sort -n

You may need to wait at least a minute or so (depending on what your old values were) to see a change here.
