C# DOOR32.SYS BBSLink Client

If you have heard of or came across http://bbslink.net/ and wanted to add the services door games to your BBS but find that they only offer a javascript file for Synchronet BBSes then this might help you out.

I recently joined and not having a Synchronet BBS I had to make my own client to work with their service. As promised I am also releasing the source.

It is written in C# against .NET 2.0 and *might* work in mono on linux. You will have to test.

Local Binary: BBSLink Door Binaries
Local Source: BBSLink Door Source Code
GitHub Binary/Source: https://github.com/zharvek/BBSLink

Update: I made a small change to the dropped carrier handling and disconnections. The door should now handle dropped carrier and exit correctly. Let me know if you have issues.

Updated BBS Connection Page

I have removed the flash versions of the telnet client on the website and replaced with an HTML5 HTTPS Websockets only applet. All connections to the BBS from this website are 100% encrypted. Downloading and uploading files works as well through the applet, which was the only reason I was keeping the flash version around. If you are connecting via telnet client instead of the applet, your connections are not encrypted. Just a heads up.

Updating Kolab 3.1 or 3.2 to 3.3

I have recently updated my Kolab Groupware install from version 3.2 to version 3.3, there are not a ton of new features but I wanted to see if this would be a huge process or go fairly quickly.

First of all, take a backup. Really take a backup. You never know what your going to blow up with Kolab updates. Sometime they work great, and they are getting better. Just do it. At the very least backup your IMAP store. If you are like me at all and have your IMAP mounted over NFS, stop the Cyrus service and unmount the IMAP store.

Also, I am using CentOS 6 this guide will be based on that, the fixes at the end might apply though if you are not running CentOS 6.

Here is what I did, also I will list a few things I did to fix some issues.

Backup the server. I use VMWare ESX so I made a snapshot.

Stop the Cyrus Server.
service cyrus-imapd stop

I unmounted the IMAP store since I use NFS.
umount /var/spool/imap

Follow this guide (I will copy it’s content below, possibly with some differences).
https://docs.kolab.org/administrator-guide/upgrading-from-kolab-3.1-to-3.3.html

Update your CentOS Installation

# cd /etc/yum.repos.d/
# rm Kolab*.repo
# wget http://obs.kolabsys.com/repositories/Kolab:/3.3/CentOS_6/Kolab:3.3.repo
# wget http://obs.kolabsys.com/repositories/Kolab:/3.3:/Updates/CentOS_6/Kolab:3.3:Updates.repo
# yum update

FILE TO EDIT: /etc/kolab/kolab.conf
Replace example.org with your LDAP and installation primary domain name.

[ldap]
sharedfolder_acl_entry_attribute = acl
modifytimestamp_format = %Y%m%d%H%M%SZ

[kolab_smtp_access_policy]
delegate_sender_header = True
alias_sender_header = True
sender_header = True
xsender_header = True
cache_uri = 

[wallace]
modules = resources, invitationpolicy, footer
kolab_invitation_policy = ACT_ACCEPT_IF_NO_CONFLICT:example.org, ACT_MANUAL

If you’re planning to make use of wallace please make sure wallace is enabled to start using chkconfig on RHEL/Centos or /etc/default/wallace on debian.

# service kolab-server restart
# service wallace restart

FILE TO EDIT: /etc/kolab-freebusy/config.ini
Instead of editing the configuration by hand it’s easier to just recreate the configuration using the setup-kolab tool. Your choice.
This step did not work for me, but I do not use freebusy!

# cp /etc/kolab-freebusy/config.ini.rpmnew /etc/kolab-freebusy/config.ini
or
# setup-kolab freebusy

FILE TO EDIT: /etc/roundcubemail/config.inc.php
The plugins where correct on my server excepting adding the new ones, kolab_notes and kolab_tags.

Change the plugin load order the follwing way:

    move kolab_auth to the top position
    move kolab_config after kolab_addressbook
    add kolab_notes after kolab_folders
    add kolab_tags after kolab_notes
$config['use_secure_urls'] = true;
$config['assets_path'] = '/roundcubemail/assets/';

FILE TO EDIT: /etc/roundcubemail/password.inc.php
Change the password driver from ldap to ldap_simple.

$config['password_driver'] = 'ldap_simple';

FILE TO EDIT: /etc/roundcubemail/kolab_files.inc.php
Update the kolab_files_url to /chwala/ to be protocol independent.
This would not work for me, I kept my old setup.

$config['kolab_files_url'] = '/chwala/';

FILE TO EDIT: /etc/iRony/dav.inc.php
The iRony configuration doesn’t have anything special configurations. You might want to consider just to take the new default config file or change it based on the differences between the previous version.
For me, nothing changed from 3.2 to 3.3 but you should check.

# cp /etc/iRony/dav.inc.php.rpmnew /etc/iRony/dav.inc.php

FILE TO EDIT: /etc/postfix/ldap/virtual_alias_maps_sharedfolders.cf
To fix the handling of resource invitations you’ve to adjust your existing virtual alias maps, otherwise you end up with non-delivery-reports.
I just had to add the last part.
query_filter = (&(|(mail=%s)(alias=%s))(objectclass=kolabsharedfolder)(kolabFolderType=mail))

FILE TO EDIT: /etc/postfix/master.cf
This will put wallace as the next content-filter after the mail has been returned from amavis to postfix. If you’re don’t want to make use of iTip processing or resource management you can skip this section.

[...]
127.0.0.1:10025     inet        n       -       n       -       100     smtpd
    -o cleanup_service_name=cleanup_internal
    -o content_filter=smtp-wallace:[127.0.0.1]:10026
    -o local_recipient_maps=

Restart Postfix

# service postfix restart

Update MySQL Database
Connect to MySQL, use the password you use for SQL on that server.

Go ahead and restart the server now to load stuff, you don’t really have to I suppose.

Stuff I fixed/updated/changed to make stuff work….

The assets will not load, images, css and such on roundcube web interface:

Edit /etc/roundcubemail/config.inc.php and change

$config['assets_path'] = '/roundcubemail/assets/';

to

$config['assets_path'] = '/assets/';

Still no assets, using SSL? No images and stuff? Let’s check your Apache configuration. I had to add an Include line in the ssl.conf

Edit /etc/httpd/conf.d/ssl.conf
I just added the Include line below, your setup may be different as some people use a VHOST some use SSL some use mod_ssl (like me) some use other SSL setups. Some people need to include the roundcubemail.conf and some won’t.

#SSLRequire (    %{SSL_CIPHER} !~ m/^(EXP|NULL)/ \
#            and %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \
#            and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"} \
#            and %{TIME_WDAY} >= 1 and %{TIME_WDAY} <= 5 \
 #            and %{TIME_HOUR} >= 8 and %{TIME_HOUR} <= 20       ) \
 #           or %{REMOTE_ADDR} =~ m/^192\.76\.162\.[0-9]+$/
 #

Include conf.d/roundcubemail.conf

#   SSL Engine Options:

Okay, I also use a custom port number with my setup to access the web, it’s SSL but it’s not on port 443. You need to turn off secure_urls and change a PHP variable.
Edit /etc/roundcubemail/config.inc.php

$config['use_secure_urls'] = false;

Edit /usr/share/roundcubemail/program/include/rcmail_output_html.php
Line ~187. You can see I changed the $_SERVER line to be HTTP_HOST this will catch the custom port.

                $base = implode('/', $_base);
            }

            $path = (rcube_utils::https_check() ? 'https' : 'http') . '://'
                . $_SERVER['HTTP_HOST'] . $base . '/' . $path;
        }

        $this->assets_path = $path;
        $this->set_env('assets_path', $path);

Do you use the files portion of Kolab and it’s not working? Lets check our configuration for Chwala.

Edit /usr/share/roundcubemail/config/kolab_files.inc.php
Here is my file, check the top lines, the URL fields. I at one point needed to specify HTTPS, maybe you do. I no longer need to.

Have an android device or other Exchange client that you know supports sub-folders and user created folders and they never show up? Do the emails all clump together in the inbox? Try this.

Edit /usr/share/kolab-syncroton/lib/kolab_sync_data_email.php
Line ~108. Change the windowsoutlook15 to android

    public function __construct(Syncroton_Model_IDevice $device, DateTime $syncTimeStamp)
    {
        parent::__construct($device, $syncTimeStamp);

        $this->storage = rcube::get_instance()->get_storage();

        // Outlook 2013 support multi-folder
        //$this->ext_devices[] = 'windowsoutlook15';
        $this->ext_devices[] = 'android';

        if ($this->asversion >= 14) {
            $this->tag_categories = true;
        }
    }

Make sure you go into roundcube settings, and then folders. Check the new folders are checked. Then settings and ActiveSync and under your device check the new folders as well.

After everything was good, I was still getting some odd errors with the notes portion. I could make a new Noteboot in Roundcube and add notes there, but I could not add or move notes into the primary notebook ‘Notes’ I kept getting an error. My androids could not add or read notes from it either. Very odd. After poking around I figured it’s probably something with the IMAP storage portion. I was right for my issue, and this is what I did.

Login to kolab server using SSH or console as root and then change user to cyrus.

su - cyrus

If you get an error with that command, then you need to probably check the login shell for cyrus. I changed the users login shell to bash.

usermod -s /bin/bash cyrus

Once you are running as Cyrus we need to reconstruct the IMAP mailbox.

cd /usr/lib/cyrus-imapd
./reconstruct -r user/test.user

For me the user/test.user was user/[email protected]

While here I also ran

./cyr_expire -E 3 -D 3 -X 3

To remove some deleted crap and clear out stuff.

BBS Update

It has been a while since I have posted anything.

I now have some more free time and will be adding more IGMs to the LORD game and doing more stuff to the BBS. I may also be moving the BBS outside of my home and to my externally hosted VMware setup, this should provide more stability, uptime and will also provide more bandwidth for everyone. Nothing will be affected by the move when it happens.

BBS has been moved and I have fixed a few links on the website for force into HTTPS mode.

Reddit Posts on Archaic Binary BBS

I have been asked on the BBS how I pulled reddit links into the BBS for callers to see. As you might know, I have been using RMLib to make some simple door utilities with C#.

My latest utility pulls some headlines from reddit, as well as showing recent activity on the board.

Here is the code that does this… I don’t want to release the full program source yet, as it has other stuff I need to finish up. Sorry.
Using this though you should be able to get a C# door running with RMLib.


WebClient w = new WebClient();
            string s = w.DownloadString("http://www.reddit.com/r/tech");
            string cleanString = "";
            string cleanURL = "";

            foreach (LinkItem i in LinkFinder.Find(s))
            {
                cleanString = Regex.Replace(i.Text.ToString(), @"[^\u0000-\u007F]", string.Empty);
                cleanURL = Regex.Replace(i.Href.ToString(), @"[^\u0000-\u007F]", string.Empty);
                Door.WriteLn(StringUtils.PadRight(cleanString, ' ', 57) + " | ");
                Door.WriteLn(StringUtils.PadRight(cleanURL, ' ', 57) + " | ");
                Door.WriteLn(StringUtils.PadRight(" ", ' ', 57) + " | ");
            }
