Create an ipv6 site and connect to it

On Kimsufi, get the current ipv6 assigned address:

ifconfig
...
eth0      Link encap:Ethernet  HWaddr 00:22:4d:ad:aa:b7  
          inet addr:5.346.26.43  Bcast:5.346.26.43  Mask:255.255.255.0          
          inet6 addr: 4001:43d0:a:fa2b::1/128 Scope:Global
          inet6 addr: fe80::222:4dff:fead:aab7/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:21749596 errors:0 dropped:0 overruns:0 frame:0
          TX packets:13397719 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:18551028720 (17.2 GiB)  TX bytes:2813996773 (2.6 GiB)
          Interrupt:16 Memory:d0400000-d0420000 
...

So 4001:43d0:a:fa2b::1/128 denotes the first ipv6 assigned to us. Though it says only a /128 (one ipv6) is assigned, we actually have a whole /64 block. To assign another, add:

ip addr add 4001:43d0:a:fa2b::2/128 dev eth0

Check it has been added:

ifconfig
...
eth0      Link encap:Ethernet  HWaddr 00:22:4d:ad:aa:b7  
          inet addr:5.346.26.43  Bcast:5.346.26.43  Mask:255.255.255.0         
          inet6 addr: 4001:43d0:a:fa2b::2/128 Scope:Global 
          inet6 addr: 4001:43d0:a:fa2b::1/128 Scope:Global
          inet6 addr: fe80::222:4dff:fead:aab7/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:21749596 errors:0 dropped:0 overruns:0 frame:0
          TX packets:13397719 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:18551028720 (17.2 GiB)  TX bytes:2813996773 (2.6 GiB)
          Interrupt:16 Memory:d0400000-d0420000 
...

If your network supports ipv6 ping to it and check (you need a ipv6 dns resolver):

ping6 4001:43d0:a:fa2b::1
PING 4001:43d0:a:fa2b::1(4001:43d0:a:fa2b::1) 56 data bytes
64 bytes from 4001:43d0:a:fa2b::1: icmp_seq=1 ttl=54 time=199 ms
64 bytes from 4001:43d0:a:fa2b::1: icmp_seq=2 ttl=54 time=218 ms
64 bytes from 4001:43d0:a:fa2b::1: icmp_seq=3 ttl=54 time=497 ms
64 bytes from 4001:43d0:a:fa2b::1: icmp_seq=4 ttl=54 time=775

ms

Add a AAAA record to point a DNS record to the ipv6 address.

What’s the onion address of the piratebay?

The onion address of the piratebay on the darknet is http://uj3wazyk5u4hnvtk.onion. Of course, you need the tor browser to access it. Use it if your ISP blocks piratebay proxies. In fact most proxies are nowdays riddled with ads. The original piratebay doesnt, so you can use tor if you hate ads.

Using cloudflare command line interface

You can easily change anything in your Cloudflare dashboard from the linux command line.

Install the cli

npm install -g cloudflare-cli

By default cfcli will look for “.cfcli.yml” in your home directory (you can also pass in a config file with -c). So create this:

emacs ~/.cfcli.yml
defaults:
    token: fcbe3cbb2894cb5f1871c89222851bf1
    email: [email protected]
    domain: oneofyourdomains.com

The token is actually the Cloudflare Global API key which you can retrieve from My Settings>Account>API Key menu.
All options:

NAME
    cfcli - Interact with cloudflare from the command line
 
SYNOPSIS
    cfcli [options] command [parameters]
 
OPTIONS:
    -c  --config    Path to yml file with config defaults (defaults to ~/.cfcli.yml
    -e  --email     Email of your cloudflare account
    -k  --token     Token for your cloudflare account
    -u  --account   Choose one of your named cloudflare accounts from .cfcli.yml
    -d  --domain    Domain to operate on

    -p  --priority  Set priority when adding a record (MX or SRV)
    -l  --ttl       Set ttl on add or edit (120 - 86400 seconds, or 1 for auto)
    -h  --help      Display help
 
COMMANDS:
    add <name> <content>
        Add a DNS record. Use -a to activate cf after creation
    devmode on|off
        Toggle development mode on/off
    disable <name> [content]
        Disable cloudflare caching for given record and optionally specific value

Adding a letencrypt certificate for a server running seafile server

The regular letsencrypt certbot procedure fails due to reverse proxying-it essentially means that contrary to regular delivery of webpage content, where you type an address and apache serves the content from a specific folder, seafile runs a service as a reverse proxy. Apache binds to the particular port running seafile, and serves content provided by the seafile daemon (service). So obviously letsencrypt authorization doesnt work regularly. I struggled with a lot of apparent techniques for the reverse proxy, all of which threw up all kinds of errors while letsencrypt was authorizing in apache mode. Finally the solution is very simple-use letsencrypt certbot in manual DNS verification mode. It’s simple-you just add a particular TXT record to your DNS, and Cloudflare instantly verifies it and provides you the certificate, CSR and chain.

certbot -d yourdomain.com --manual --preferred-challenges dns certonly

Detail
======
Seafile client stores all its configure information in a config dir. The default location is `~/.ccnet`. All the commands below accept an option `-c <config-dir>`.
init
----
Initialize seafile client. This command initializes the config dir. It also creates sub-directories `seafile-data` and `seafile` under `parent-dir`. `seafile-data` is used to store internal data, while `seafile` is used as the default location put downloaded libraries.
    seaf-cli init [-c <config-dir>] -d <parent-dir>
start
-----
Start seafile client. This command start `ccnet` and `seaf-daemon`, `ccnet` is the network part of seafile client, `seaf-daemon` manages the files.
    seaf-cli start [-c <config-dir>]
stop
----
Stop seafile client.
    seaf-cli stop [-c <config-dir>]
Download
--------
Download a library from seafile server
    seaf-cli download -l <library-id> -s <seahub-server-url> -d <parent-directory> -u <username> -p <password>
sync
----
Synchronize a library with an existing folder.
    seaf-cli sync -l <library-id> -s <seahub-server-url> -d <existing-folder> -u <username> -p <password>

First retrieve the library id by browsing on the server -> it's in the url after "/repo/"

usage: seaf-cli sync [-h] [-c CONFDIR] [-l LIBRARY] [-s SERVER] [-u USERNAME]
                     [-p PASSWORD] [-d FOLDER]

optional arguments:
  -h, --help            show this help message and exit
  -c CONFDIR, --confdir CONFDIR
                        the config directory
  -l LIBRARY, --library LIBRARY
                        library id
  -s SERVER, --server SERVER
                        URL for seafile server
  -u USERNAME, --username USERNAME
                        username
  -p PASSWORD, --password PASSWORD
                        password
  -d FOLDER, --folder FOLDER
                        the existing local folder


desync
------
Desynchronize a library from seafile server
    seaf-cli desync -d <existing-folder>
create
------
Create a new library
    seaf-cli create -s <seahub-server-url> -n <library-name> -u <username> -p <password> -t <description> [-e <library-password>]
'''

Get library id:

seaf-cli list-remote -s  "https://cloud.joel.co.in" -u "[email protected]" -p "mypassword"
Name    ID
My Library d9d122233-43b6-4af3-21dde-59aawwwww45df11

Now download to local folder:

seaf-cli download -l "d9d122233-43b6-4af3-21dde-59aawwwww45df1" -s  "https://cloud.joel.co.in" -d /tmp/lib -u "[email protected]" -p "mypassword"
Starting to download ...
Library d9d122233-43b6-4af3-21dde-59aawwwww45df1 will be downloaded to /tmp/lib

Now add to this directory:

cp /tmp/att/* /tmp/lib/My\ Library/Shanghumukham-April\ 2017/Arun/

You dont need to upload/sync after adding files. The daemon automatically does that. In fact, if you attempt to sync you get an error:

seaf-cli sync -l "d9d122233-43b6-4af3-21dde-59aawwwww45df1" -s  "https://cloud.joel.co.in" -d /tmp/lib -u "[email protected]" -p "mypassword"

It may be a good option to desync at the end lest you end up deleting needed folders/files.

Stopping sync:

seaf-cli desync -d /tmp/lib/My\ Library

Syncing to existing local library after desyncing:

seaf-cli sync -l "d9d122233-43b6-4af3-21dde-59aawwwww45df1" -d /root/SeafileLocalSync -s  "https://cloud.joel.co.in" -u "[email protected]"

Seafile client for a Cli server
Installation
You can follow this documentaion to install Seafile CLI client on various Linux distributions.

Basic Usage
Initialise & start the client

# choose a folder where to store the seafile client settings e.g ~/seafile-client
mkdir ~/seafile-client            # create the settings folder
seaf-cli init -d ~/seafile-client  # initialise seafile client with this folder
seaf-cli start
Download a library from a server

retrieve the library id by browsing on the server -> it's in the url after /repo/
then
seaf-cli download -l "the id of the library" -s  "the url + port of server" -d "the folder where the library folder will be downloaded" -u "username on server" [-p "password"]
seaf-cli status  # check status of ongoing downloads
# Name  Status  Progress
# Apps    downloading     9984/10367, 9216.1KB/s
Note: if you not supply the password parameter in the command, it will be asked later, which is more safe.

Example: `seaf-cli download -l 0536c006-8a43-449e-8718-39f12111620d -s http://cloud.seafile.com -d /tmp -u [email protected]`
Download a library from a server and sync with an existing folder.

# This is the same as download : replace download by sync 
seaf-cli sync -l "the id of the library" -s  "the url + port of server" -d "the folder where the library will be synced with" -u "username on server" -p "password"
Man documentation
seaf-cli is command line interface for seafile client.

Subcommands:

init                Initialize config directory
start               Start ccnet and seafile daemon
stop                Stop ccnet and seafile daemon
list                List local libraries
list-remote         List remote libraries
status              Show syncing status
download            Download a library from seafile server
download-by-name    Download a library defined by name from seafile server
sync                Sync a library with an existing foler
desync              Desync a library with seafile server
create              Create a library
config              Configure seafile client
Running seaf-cli -h will show the above help. For each subcommand, you can also use -h option to get help, e.g. seaf-cli download -h.

Detail
Seafile client stores all its configure information in a config dir. The default location is ~/.ccnet. All the commands below accept an option -c <config-dir>.

init
Initialize seafile client. This command initializes the config dir. It also creates sub-directories seafile-data and seafile under parent-dir. seafile-data is used to store internal data, while seafile is used as the default location put downloaded libraries.

seaf-cli init [-c <config-dir>] -d <parent-dir>
A file named seafile.ini will be created under ~/.ccnet to record the location of seafile-data directory.

If you want to run multiple instances of Seafile cli client in the same machine, you can specify different config-dir and parent-dir when initializing different client instances. Then the instances can run without interfering each others. When starting the instances, just specify ccnet config directories with the -c option.

start
Start seafile client. This command start ccnet and seaf-daemon, ccnet is the network part of seafile client, seaf-daemon manages the files.

seaf-cli start [-c <config-dir>]
stop
Stop seafile client.

seaf-cli stop [-c <config-dir>]
Download
Download a library from seafile server

seaf-cli download -l <library-id> -s <seahub-server-url> -d <parent-directory> -u <username> [-p <password>]
sync
Synchronize a library with an existing folder.

seaf-cli sync -l <library-id> -s <seahub-server-url> -d <existing-folder> -u <username> [-p <password>]
desync
Desynchronize a library from seafile server

seaf-cli desync -d <existing-folder>
create
Create a new library on server

seaf-cli create [-h] -n library-name -t description [-e library-password] -s server -u username -p password
Skip SSL certificate verify
If you're using self-signed certificate on the server, you should ask the client to skip verifying certificate.

seaf-cli config -k disable_verify_certificate -v true
Set Transfer Speed Limit
Set upload speed limit to 1MB/s :

seaf-cli config -k upload_limit -v 1000000
Set download speed limit to 1MB/s :

seaf-cli config -k download_limit -v 1000000

To sync your Dropbox folder to a new library in Seafile, create a library in Seafile named Dropbox. Then install Dropbox headless on the server and start the daemon:

64-bit:

cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -

Next, run the Dropbox daemon from the newly created .dropbox-dist folder. You will need to authorize after starting the daemon:

~/.dropbox-dist/dropboxd
Dowload the Dropbox helper python script if you want fine grained control:
wget https://www.dropbox.com/download?dl=packages/dropbox.py
mv download\?dl\=packages%2Fdropbox.py dropbox.py
chmod +x dropbox.py
./dropbox.py

Now create a library in Seafile, note its library id (the sequence after /lib/)
Make seafile sync to existing Drobox directory

seaf-cli sync -l [libid] -s "https://cloud.yoursom.com" -u [Username] -d ~/Dropbox

To sync Google Drive:
First install the cli:
apt-get install git cmake build-essential libgcrypt11-dev libyajl-dev \
libboost-all-dev libcurl4-openssl-dev libexpat1-dev libcppunit-dev binutils-dev
git clone https://github.com/Grive/grive.git
cd grive
dpkg-buildpackage -j4 -uc -us
dpkg -i ../grive*deb
mkdir ~/GoogleDrive
cd ~/GoogleDrive
grive -a
seaf-cli sync -l [libid] -s “https://cloud.yoursom.com” -u [Username] -d ~/GoogleDrive
grive &
[/bash]

grive doesnt run as a daemon, so create a cron job to sync files every 5 minutes:

*/5 * * * * cd /root/GoogleDrive && /usr/bin/grive

Fix seafile server for folder names containing spaces

This is an apache bug.

Use a newer apache version:

Generic steps to install a newer version of a package with apt than provided in the stable stream:

In /etc/apt/apt.conf.d add the following file

99defaultrelease:

APT::Default-Release "stable";

In /etc/apt/sources.list.d – add urls for testing / unstable sources

stable.list:

deb     http://ftp.de.debian.org/debian/    stable main contrib non-free
deb-src http://ftp.de.debian.org/debian/    stable main contrib non-free

deb     http://security.debian.org/         stable/updates  main contrib non-free

testing.list:

deb     http://ftp.de.debian.org/debian/    testing main contrib non-free
deb-src http://ftp.de.debian.org/debian/    testing main contrib non-free

deb     http://security.debian.org/         testing/updates  main contrib non-free
run
apt-get update

and then install what you need with

apt-get -t testing install something

So for our purpose:

apt-get update
apt-get -t testing install apache2
service apache2 restart

Choose to keep all your default config files with no changes.
