+# Server Installation for jitmeet
+
+This describes configuring a server `jitmeet.example.com`.  You will nedd to
+change references to that to match your host, and generate some passwords for
+`YOURSECRET1` and `YOURSECRET2`.
+
+There are also some complete [example config files](https://www.dropbox.com/sh/jgp4s8kp6xuyubr/5FACgJmqLD) available, mentioned in each section.
+
+## Install prosody and otalk modules
+```sh
+echo deb http://packages.prosody.im/debian $(lsb_release -sc) main | sudo tee -a /etc/apt/sources.list
+wget --no-check-certificate https://prosody.im/files/prosody-debian-packages.key -O- | sudo apt-key add -
+apt-get update
+apt-get install prosody-trunk
+apt-get install git lua-zlib lua-sec-prosody lua-dbi-sqlite3 liblua5.1-bitop-dev liblua5.1-bitop0
+git clone https://github.com/andyet/otalk-server.git
+cd otalk-server
+cp -r mod* /usr/lib/prosody/modules
+```
+
+## Configure prosody
+Modify the config file in `/etc/prosody/prosody.cfg.lua` (see also the example config file):
+
+- modules to enable/add: compression, bosh, smacks3, smacks2, carbons, mam, lastactivity, offline, pubsub, adhoc, websocket, http_altconnect
+- comment out: `c2s_require_encryption = true`, and `s2s_secure_auth = false`
+- change `authentication = "internal_hashed"`
+- add this:
+```
+daemonize = true
+cross_domain_bosh = true;
+storage = {archive2 = "sql2"}
+sql = { driver = "SQLite3", database = "prosody.sqlite" }
+default_archive_policy = "roster"
+```
+- configure your domain by editing the example.com virtual host section section:
+```
+VirtualHost "jitmeet.example.com"
+authentication = "anonymous"
+ssl = {
+    key = "/var/lib/prosody/jitmeet.example.com.key";
+    certificate = "/var/lib/prosody/jitmeet.example.com.crt";
+}
+```
+- and finally configure components:
+```
+Component "conference.jitmeet.example.com" "muc"
+Component "jitsi-videobridge.jitmeet.example.com"
+    component_secret = "YOURSECRET1"
+```
+
+Generate certs for the domain:
+```sh
+prosodyctl cert generate jitmeet.example.com
+```
+
+Restart prosody XMPP server with the new config
+```sh
+prosodyctl restart
+```
+
+## Install nginx
+```sh
+apt-get install nginx
+```
+
+Add nginx config for domain in `/etc/nginx/nginx.conf`:
+```
+tcp_nopush on;
+types_hash_max_size 2048;
+server_names_hash_bucket_size 64;
+```
+
+Add a new file `jitmeet.example.com` in `/etc/nginx/sites-available` (see also the example config file):
+```
+server {
+    listen 80;
+    server_name jitmeet.example.com;
+    # set the root
+    root /srv/jitmeet.example.com;
+    index index.html;
+    location ~ ^/([a-zA-Z0-9]+)$ {
+        rewrite ^/(.*)$ / break;
+    }
+    # BOSH
+    location /http-bind {
+        proxy_pass      http://localhost:5280/http-bind;
+        proxy_set_header X-Forwarded-For $remote_addr;
+        proxy_set_header Host $http_host;
+    }
+    # xmpp websockets
+    location /xmpp-websocket {
+        proxy_pass http://localhost:5280;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+        proxy_set_header Host $host;
+        tcp_nodelay on;
+    }
+}
+```
+
+Add link for the added configuration
+```sh
+cd /etc/nginx/sites-enabled
+ln -s ../sites-available/jitmeet.example.com jitmeet.example.com
+```
+
+## Fix firewall if needed
+```sh
+ufw allow 80
+ufw allow 5222
+```
+
+## Install videobridge
+```sh
+wget https://download.jitsi.org/jitsi-videobridge/linux/jitsi-videobridge-linux-{arch-buildnum}.zip
+unzip jitsi-videobridge-linux-{arch-buildnum}.zip
+```
+
+Install JRE if missing:
+```
+apt-get install default-jre
+```
+
+In the user home that will be starting the jitsi video bridge create `.sip-communicator` folder and add the file `sip-communicator.properties` with one line in it:
+```
+org.jitsi.impl.neomedia.transform.srtp.SRTPCryptoContext.checkReplay=false
+```
+
+Start the videobrdige with:
+```sh
+./jvb.sh --host=localhost --domain=jitmeet.example.com --port=5347 --secret=YOURSECRET1 &
+```
+Or autostart it by adding the line in `/etc/rc.local`:
+```sh
+/bin/bash /root/jitsi-videobridge-linux-{arch-buildnum}/jvb.sh --host=localhost --domain=jitmeet.example.com --port=5347 --secret=YOURSECRET1 </dev/null >> /var/log/jvb.log 2>&1
+```
+
+Checkout and configure jitmeet:
+```sh
+cd /srv
+git clone https://github.com/jitsi/jitmeet.git
+mv jitmeet/ jitmeet.example.com
+```
+
+Edit host names in `/srv/jitmeet.example.com/config.js` (see also the example config file):
+```
+var config = {
+    hosts: {
+        domain: 'jitmeet.example.com',
+        muc: 'conference.jitmeet.example.com',
+        bridge: 'jitsi-videobridge.jitmeet.example.com'
+    },
+    useNicks: false,
+    bosh: '//jitmeet.example.com/http-bind' // FIXME: use xep-0156 for that
+    desktopSharing: 'ext', // Desktop sharing method. Can be set to 'ext', 'webrtc' or false to disable.
+    chromeExtensionId: 'diibjkoicjeejcmhdnailmkgecihlobk', // Id of desktop streamer Chrome extension
+    minChromeExtVersion: '0.1' // Required version of Chrome extension
+};
+```
+
+Restart nginx to get the new configuration:
+```sh
+invoke-rc.d nginx restart
+```
+
+
+## Install [Turn server](https://github.com/andyet/otalk-server/tree/master/restund)
+```sh
+apt-get install make gcc
+wget http://creytiv.com/pub/re-0.4.7.tar.gz
+tar zxvf re-0.4.7.tar.gz
+ln -s re-0.4.7 re
+cd re-0.4.7
+sudo make install PREFIX=/usr
+cd ..
+wget http://creytiv.com/pub/restund-0.4.2.tar.gz
+wget https://raw.github.com/andyet/otalk-server/master/restund/restund-auth.patch
+tar zxvf restund-0.4.2.tar.gz
+cd restund-0.4.2/
+patch -p1 < ../restund-auth.patch
+sudo make install PREFIX=/usr
+cp debian/restund.init /etc/init.d/restund
+chmod +x /etc/init.d/restund
+cd /etc
+wget https://raw.github.com/andyet/otalk-server/master/restund/restund.conf
+```
+
+Configure addresses and ports as desired, and the password to be configured in prosody:
+```
+realm           jitmeet.example.com
+# share this with your prosody server
+auth_shared     YOURSECRET2
+
+# modules
+module_path     /usr/lib/restund/modules
+turn_relay_addr [turn ip address]
+```
+
+Configure prosody to use it in `/etc/prosody/prosody.cfg.lua`.  Add to your virtual host:
+```
+turncredentials_secret = "YOURSECRET2";
+turncredentials = {
+    { type = "turn", host = "turn.address.ip.configured", port = 3478, transport = "tcp" }
+}
+```
+
+Reload prosody if needed
+```
+prosodyctl reload
+telnet localhost 5582
+module:reload("turncredentials", "jitmeet.example.com")
+quit
+```
+
+## Running behind NAT
+In case of videobridge being installed on a machine behind NAT, add the following extra lines to the file `~/.sip-communicator/sip-communicator.properties` (in the home of user running the videobridge):
+```
+org.jitsi.videobridge.NAT_HARVESTER_LOCAL_ADDRESS=<Local.IP.Address>
+org.jitsi.videobridge.NAT_HARVESTER_PUBLIC_ADDRESS=<Public.IP.Address>
+```
+
+So the file should look like this at the end:
+```
+org.jitsi.impl.neomedia.transform.srtp.SRTPCryptoContext.checkReplay=false
+org.jitsi.videobridge.NAT_HARVESTER_LOCAL_ADDRESS=<Local.IP.Address>
+org.jitsi.videobridge.NAT_HARVESTER_PUBLIC_ADDRESS=<Public.IP.Address>
+```
