This is a free Linux shell server, which accepts donations to the Bitcoin address below!



System



Instant account creation after you win a text pong game. Takes 6 to 12 minutes. See Account Creation below.



IRC and background processes are allowed.

IP addresses: Most reliable: 2001:470:1f11:209::13 and France IP 92.222.41.125 . User contributed domain blinuxshell.ir also.



Bandwidth is limited. Think of not using more than 12KB/sec average, but higher burst is okay. That is to say, please don't set up a proxy and then stream media through it all day even when you are not home to listen to it.



You have 128MiB of disk space, and 6000 files max.

$50 cash reward if you exploit root and shut the system down securely.

95% network uptime. Server usually runs for months with several reboots in between.



There's a limit of 100 processes.

Outgoing mail port 25 is blocked.



The test and guest accounts have a single space for the password and can be used by anyone but they are blocked from network access.



Accounts are not deleted until necessary to free up space. If you haven't logged in for a long time (months), the more disk space you are using puts closer to the head of the line of accounts that have to be erased. You may want to not leave unpacked sources from programs which you have compiled sitting taking up space.



Account Creation



telnet bitcoinshell.mooo.com 2015. Windows users can download Dave's Telnet. It's just a .zip and doesn't need admin rights to use. Click Connect then Remote System... Set Host: bitcoinshell.mooo.com , Port: 2015 , Protocol: Telnet TERM: xterm then press OK . You can also use the Windows telnet program. You can't make multiple accounts from the same IP address. Non windows users can use netcat: $ nc bitcoinshell.mooo.com 2016, but line buffering may be a problem with the game. You can change your password to something better once you've logged in securely through ssh.*



Connecting



ssh or telnet to your account name at bitcoinshell.mooo.com (or 92.222.41.125 / 2001:470:1f11:209::13). If your Internet connection is crippled, Port 443 can be used! If you're using Windows, download PuTTY and run it. Set Host Name to bitcoinshell.mooo.com and select SSH. FTP is available. You can put ftp://username:password@bitcoinshell.mooo.com/ in Windows explorer and access all your files easily, but remember that your password will probably be sent in the clear.

Using your account

screen can be used to keep a program running after you logout, and then get back to it with screen -r. Press Ctrl+A then ? for screen help.

VNC ! Run vncserver to start a virtual X server, start your GUI applications, then connect to it with vncviewer or a compatible viewer remotely as needed. It's the same concept as using screen or tumx and text only applications. Ask about it and questions like what $DISPLAY= should be in the IRC channel.

The eggdrop files are symlinked in to $HOME/.eggdrop/botname. You can move, rename and make copies of that directory. If you install your own bot, it's best to run multiple instance the same eggdrop executable in the same directory using a different configuration file, such as ./eggdrop -m bot1.conf. The file paths for log files and such in the eggdrop configuration files should be different for each bot. If you copy your whole eggdrop directory for each bot you end up wasting disk space. You can also make additional eggdrop directories and symlink all the required files in to it from your primary eggdrop directory, as eggdrop-installer does.

Since this is Gentoo Linux, most development software is installed.

You are the administrator of your user group, which has the same name as your user name. This allows you to add other users to it for sharing access to files. If you created two accounts, this could be useful.

/var/www/localhost/htdocs/users/ contains directories where you can put files on the HTTP server. Executables ending in .cgi or .fcg will run as CGI or FastCGI scripts. If you get an Internal Server Error, check for permissions which are too permissive, and $ tail /var/log/apache2/suexec_log .

If you run too many processes and prevent yourself from logging in to your account, you can fix it using the user account creation shell.

To delete your account, just rm -rf ~ to delete all the files, then "$ touch DELETE_ME " (make an empty file). Do $ cp /etc/skel/.* ~ to put the default files back if you want to use it again.

If you're running *nix, or OS X, or Cygwin in Windows, graphical X11 programs can connect to your local X11 display over the Internet, so long as they use accelerated X11 functions do not contain any animated graphics. This includes most simple GUI applications. Just $ xhost +bitcoinshell.mooo.com on your computer, make sure your port TCP port 6000 is open and your X server is configured to listen for remote connections, and then on the shell do: $ DISPLAY="yourIPaddress:0.0" xcalc" to test. You may explore other more advanced things like using X11 with compression and possibly security enabled.

You may explore other more advanced things like using X11 with compression and possibly security enabled. If your running processes consume a lot of virtual memory, they may get terminated. It's best to free() memory that is no longer needed. Memory that is allocated but is not used still counts as used virtual memory. Many programs take advantage of Linux's lazy memory allocation and allocate more than they need, since it doesn't actually use up memory until it is written to.

Using your account - Installing programs on your own

Many users are used to installing programs system wide as root, by either installing to the usual default /usr/local/ directory or by using a system package manager. This is one reason why VPS services are popular. But it's not necessary to have a high maintenance and resource inefficient VPS just to install a few programs.

For most C/C++ programs, just download the package to your home directory and unpack it with tar -xvjf or tar -xvzf or similar. For most packages, you run ./configure --prefix=$HOME. ./configure --help gives you a list of package options. The CFLAGS variable should be set for you already, so your package will be optimally compiled. Next run make, and then make install to install it to where you specified with --prefix=. Some packages are more complicated and require you to run things like autoconf and automake first.

Often you will need to install a shared library for your package. The instructions for installing a library in to your home directory are basically the same, but you have to configure your programs to look in the directory where you installed it, else it will never be loaded. You do this with the LD_LIBRARY_PATH environmental variable. Type export LD_LIBRARY_PATH=$HOME/lib if you installed your library in /home/yourname/lib. Once that's working add that line to your .bash_profile so it will be set automatically. If you are having trouble getting an executable to load, you can type ldd ./yourprogram to list all the libraries which it needs, and which ones could not be found. If you are compiling a program which uses the shared library, you will also have to add -I and -l options to the CFLAGS and/or CXXFLAGS variables so that the compiler can find the shared library's header files (.h) and shared objects (.so). For example: export CFLAGS="${CFLAGS} -I${HOME}/include -l${HOME}/lib".

Nearly everything can be made to install and run in your home directory, but it often takes a bit of knowledge of the programming language that it is written it. Libraries or modules for Perl & python programs can be installed in your home directory as well. But I don't know enough about these languages to explain how to do it.

See below about software installation requests. If it exists in the gentoo package manager, then I can install it for you.



Things to with your account (the programs mentioned have been installed)



Connect to IRC with irssi , weechat-curses , bitchx or set up bnc , psybnc , and znc .

Test software developing with Linux gcc , perl and python

Play dopewars and moon-buggy (with extra lag)



Troubleshoot your own IPv4 or IPv6 network from the outside.

Connect to region aware websites from an IP in France.

Compile and install your own programs, or download 32-bit Linux binaries.

Run a game server for a classic game or one that isn't a resource hog, such as freeciv.

In addition to running X11 graphical programs over the Internet, you can install a VNC server, have your graphical programs connect locally, and then connect remotely as needed to check up on them, similar to how you can leave irssi running in screen. VNC is uses lossy graphical transmission of the whole virtual screen, and so it's more tolerant to programs with animated graphics and such. Ask about it in the chatroom.

I don't know how to do everything. If you have an idea, ask about it. It can probably be set up and instructions can be made for everyone.



Run DOS programs virtualized with vm86 in dosemu at full speed, like a windowed DOS program on 32-bit Windows.



Requests and software installation



You can see what software is available on Gentoo Linux by running eix. eix <name> searches for packages containing that string. eix -S <string> searches the description of the package. Adding -I only matches packages which are already installed. eix -C net-irc lists all packages in the net-irc category.

Send comments and requests to axx01 on the lavabit.com email provider . I don't mind installing programs and answering questions. IRC: /server chat.freenode.net /join #bitcoinshells. Send to axx01@nomad.ignorelist.com instead. Lavabit.com has suspended operations.



Early in 2019 Bitcoinshells was reinstalled because the server was suspected to be rooted. A memory dump was collected of the old system just after booting up. Maybe there is something interesting to find in it. The root kit would likely be encryped in memory and only decrypted by a small stub of code just before use. It could also have been hiding somewhere else like in video memory and not gotten dumped. Here is the compressed dump file of the 3840MiB of usable RAM address space. Download it here

Donate with Bitcoin!



If you leave background processes running, and you're got money to spare, you can donate 0.002 BTC or $1 worth each month. You can set the last digits of the 8 decimal places to your user ID, and sent it to 15xVQHE6Z23QuS8yiU9K3erxzZi3WYz89e . That way in the future you may get priority above other non donating users. Type id to see what your UID is. For UID 2222, you would send 0.00202222 BTC.



Rules





Don't make multiple accounts to get around resource limits, or to get a different ident name. There is no reason to make a second account just to run another instance of your IRC bot or similar program. It uses twice as much disk space, and more memory since the executable must be loaded twice. Please check to see if the program you need is already installed or request it to be installed if it can be, so that all users can use a program which is loaded in to memory only once. Keep in mind that running an open proxy on standard proxy ports causes problems with IRC.

You can make another account if it is needed for security or educational reasons. Accounts created from suspicious (proxy) IP address may be removed with no warning.

Don't do anything that you wouldn't do on your own Internet connection in France!

Abuse complaints



Query identd to try to determine the owner of the network socket that is causing the problem.

You can make your own account to try to find out which user is causing the problem.



Then send an email to axx01@nomad.ignorelist.com.

Why isn't HTTPS offered on the website?Because I'm using port 443 for the alternate SSH access port. Also, I didn't think there was much need and it makes people tend to take security for granted. gmail and yahoo almost certainly share all the user's data with the government, and both of them use HTTPS. People don't care because it doesn't affect them directly (at least not that they know of). In other words, if you have something that is private, think twice about storing it on a cloud storage system. After all, this system could get cracked and the attacker could gain access to everything.

Usage examples for common tasks

This part still needs to be written! Answers to questions may go here.



To set your account time to your local time, you need to put something like: export TZ='/usr/share/zoneinfo/Asia/Kuala_Lumpur' in your .bashrc file. TZ may be needed in crontab for your cron jobs too.



To not allow others to see your .htpasswd file, do this: $ chmod 640 .htpasswd && setfacl -m u:apache:r .htpasswd



To use mail, type mail and enter the number of the message you want to read. This is a bare bones client. You can run mutt to have a somewhat better text mail interface. You should make a basic .muttrc in your $HOME like this:

set from="\"USERNAME LASTNAME\" <USERNAME@bitcoinshell.mooo.com>"

set envelope_from=yes



To make programs start automatically when the server is rebooted:

Type $ crontab -e to open the crontab editor program. For example put '@reboot znc' on a line all by itself to make znc tart up automatically. Commands are run by a shell so anything you normally type in your shell can be put after @reboot. Press ctrl+x and then Y to exit and save from nano. Your cron entry should now be installed. $ crontab -l shows you what you have in your crontab. See $ man 5 crontab for more advanced features.



To make a command run automatically at a later time, use the 'at' command to schedule it. Type $ date to see the current date, and then $ at 18:45 . Then type in your commands followed by control+D. Those commands will run at 18h45 and any output will get sent to your local email.



mcedit (or mc) needs to be run with -x to force xterm mode. Else everyting looks blue and no text shows.



To install python packages with pip in your home directory, use --user like this: pip install --user youtube-dl. That'll put it in $HOME/.local/bin/



To fix the problem where eggdrop + tcl can't find http, make sure eggdrop is compiled with the latest libtcl. It's tcl8.6 not tcl8.5. eggdrop's configure incorrectly finds libtcl8.5.so. Edit the Makefile after running configure and change libtcl8.5 to libtcl8.6 or similar. There should be three lines to edit. You can run ldd on eggdrop to see which version of libtcl it is linked agaist.

* sshd doesn't have a -L/path/to/create_account_program like telnetd does. There is no way to configure an unmodified sshd to only run a single program that I know of. Setting the program to the shell on a password less account requires using setuid root or sudo so it is too complicated and/or insecure.
