An average guy's IT (mis)adventures

Here are a few tweaks that make my "converse.js" experience better:

Remove link from banner: I accidentally used to click that and be teleported to converse.js official webclient, so I thought it could be misleading for unaware users using my locally hosted version of the software.

Search and replace/remove the href bit in converse.min.js, under the dist directory:

<a class="brand-heading" href="https://conversejs.org" target="_blank" rel="noopener">

In the "converse.min.css" file, search for this string and fill it with the following code to have unread MUCs underlined and colored in red:

.list-item.unread-msgs

.list-item.unread-msgs{font-weight:700; text-decoration: underline red;}

Fix color for toolbar-utilities when in 1:1 chats: find this line in "converse.min.css"

.fas:hover svg{fill:var(--chat-head-color)}

and replace with:

.fas:hover svg{fill:var(--chat-toolbar-btn-color)}

Raise minimum chat text area: find this bit in "converse.min.css"

min-height:var(--chat-textarea-height);

and replace with custom value in pixels, e.g.

min-height:120px;

Set a smaller line height for chats list: find the first occurrence of this code in "converse.min.css"

.conversejs .items-list .list-item

and continue until you find:

height:2.5em

substitute it with something like height:2.0em

Removing a space in quoted reply for "actions" plugin: find the following string in your conversejs/dist/plugins/actions/action.js

return ">" + nick + ' : '

remove the offending space

return ">" + nick + ': '

Changing from :smiley: to :thumbsup: emoji for the "Like" actions plugin function: find the following string in your conversejs/dist/plugins/actions/action.js

actions_reactions: [
                                    {name: 'like', label: 'Like', emoji: ':smiley:', icon_class: 'fa fa-check'},

and replace with:

actions_reactions: [
                                    {name: 'like', label: 'Like', emoji: ':thumbsup:', icon_class: 'fa fa-check'},

Fix background-color for screencast plugin icon: replace the class in row #25 in screencast.js

<button class="plugin-screencast"

<button class="btn"

Today I wanted to install yet another web frontend for the services I host, i.e. mumble-web

mumble-web is an HTML5 Mumble client for use in modern browsers.

I won't bore you with the install details, just know that it's basically JS and you need to install npm modules.. After some processing and a whole lot of deprecation warnings on screen, it finally failed. Then I looked at the logs it left and it was searching for python2!! Went back to the github page and found out the code is from about 3 years ago, with the latest issue being about one guy managing to build the software on Debian 11 with some old NodeJs version..

So, after a bit of disappointment, I delete the whole directory and be done with it. You know, there's no alternatives out there 😟

Now I would like to ask a question to disroot admins: how the hell are you running this junk on your server!? I believe they're using docker, still it's not safe in my opinion to run such old-unmaintained stuff.

I won't be doing that.

I recently moved from OVH to Contabo for my VPS: since setting up everything from scratch looked like a hard challenge, I moved everything using rsync.

Firstly, some preparations:

• installed the same kernel I had on OVH
• rebooted Contabo
• installed rsync on Contabo

Then I switched to the OVH shell:

• created a exclude.txt file with all the directory and file I didn't want to move:

/boot/
/etc/modules
/etc/fstab
/etc/mtab
/etc/netconfig
/etc/networks
/etc/network/
/etc/ssh/
/etc/cloud/
/etc/cloud-release
/etc/grub.d/
/etc/host.conf
/etc/hostname
/etc/hosts
/etc/hosts.allow
/etc/hosts.deny
/etc/init.d/cloud-config
/etc/init.d/cloud-final
/etc/init.d/cloud-init
/etc/init.d/cloud-init-local
/etc/initramfs-tools/
/etc/default/grub
/etc/default/grub.d/
/etc/kernel/
/etc/kernel-img.conf
/lib/modules/
/lost+found/
/sys/
/proc/
/dev/
/tmp/
/var/cache/
/var/log/journal/
/mnt/
/root/.ssh/

• moved it to /root/exclude.txt

• stopped all the running services

  systemctl stop <service>

• now we can begin rsync-ing: you have to have access to the root user on destination VPS

  rsync -avzP --exclude-from=/root/exclude.txt / root@CONTABO_IP:/

• after that, I edited /etc/fstab to add support for quota, like I had on OVH

• then I searched and grepped /etc for my OVH IP address, because I knew it was set somewhere on some config file

  grep -r “OVH IP” /etc/*

• and substituted it with the new Contabo IP, where necessary.

Finally, I could reboot Contabo:

reboot

Once up & running again, I changed all DNS entries from OVH to Contabo IP.. And waited 😀

• Last but not least, I edited etc/hosts manually to reflect the new Domain Name address and also set up the hostname

  hostnamectl set-hostname <new-hostname>

Done!

EDIT! A detail I missed to mention is that your destination host's root password will be changed, after rsync-ing, to the one of the source host!!

These days I am tinkering with a Mailing List for Delta Chat powered by mlmmj

I was able to create the list and set up Postfix correctly - instructions are quite clear even if on a couple settings I had to do some troubleshooting looking at logs.. Now I have this Mailing List called deltachat@woodpeckersnest.eu which you can subscribe to by sending an email to deltachat+subscribe@woodpeckersnest.eu and following further instructions.

Initially Delta Chat would create groups of people with the ML's address inside of it, thus splitting every conversation by users participating in it. This was later fixed by adding the following lines in list-dir/control/customheaders file:

X-Mailinglist: deltachat
Reply-To: deltachat@woodpeckersnest.space
List-ID: DC Mailing List <deltachat.woodpeckersnest.eu>
List-Post: <mailto:deltachat@woodpeckersnest.eu>

Now a proper Super Group is created and everyone¹ is able to message in it.

¹ Well, not actually everyone since a member still has issues but I'm positive that can be fixed by chatting again with the ML's address and removing all weird groups created earlier.

This ^ is how the supergroup looks in my chat window - the avatar is only local, it can't be set for every member but the name is the same for everyone.

Then someone "complained" for the lack of anonymity for users email addresses, like it's done in the "official" Delta Chat's MLs.. So I asked on codeberg but it seems to be a missing feature (I'm still waiting for replies 😬).

This is it for now, will keep you posted when/if I have news.

Thanks to Zash and Jcbrand in the "Converse" MUC and a bit of hacking I was able to set up a few community plugins for my conversejs install as a prosody module.

Here's the configuration in /etc/prosody/prosody.cfg.lua:

conversejs_resources = "/usr/local/lib/prosody/modules/mod_conversejs/dist"
conversejs_tags = {
        -- Load favicon
        [[<link rel="shortcut icon" href="https://woodpeckersnest.space/images/converse-js.ico">]];
        -- Load libsignal-protocol.js for OMEMO support (GPLv3; be aware of licence implications)
        [[<script src="https://cdn.conversejs.org/3rdparty/libsignal-protocol.min.js"></script>]];
        -- Load community plugins
        [[<link type="text/css" rel="stylesheet" media="screen" href="conversejs/dist/plugins/search/search.css" />]];
        [[<script src="conversejs/dist/plugins/actions/actions.js"></script>]];
        [[<script src="conversejs/dist/plugins/search/search.js"></script>]];
        [[<script src="conversejs/dist/plugins/search/jspdf.debug.js"></script>]];
        [[<script src="conversejs/dist/plugins/search/jspdf.plugin.autotable.js"></script>]];
        [[<script src="conversejs/dist/plugins/toolbar-utilities/toolbar-utilities.js"></script>]];
        [[<script src="conversejs/dist/plugins/screencast/screencast.js"></script>]];
}

conversejs_options = {
        locked_domain = "woodpeckersnest.space";
        auto_focus = true;
        view_mode = "fullscreen";
        allow_registration = false;
        auto_reconnect = true;
        reuse_scram_keys = true;
        muc_clear_messages_on_leave = true;
        clear_cache_on_logout = false;
        play_sounds = true;
        whitelisted_plugins = {"actions", "search", "toolbar-utilities", "screencast"};
}

You'll have to copy the plugins directories (actions, search etc..) in this path:

/usr/local/lib/prosody/modules/mod_conversejs/dist/plugins/

Then reload configuration and conversejs module or restart prosody.

Already found a bug in "toolbar-utilities" and haven't still had a chance to try the screencast plugin, but they look good for the most part.

Maybe I will add Jitsi Meet or Voice Chat at some point.. Not now though. ¹

EDIT: screencast is working alright, but not in the way you'd expect it. It's not a live streaming, instead it's a recording of your screen which gets uploaded once you stop the cast.. I wouldn't say it's perfect but not even bad.

¹ I've added them 😛

Remember: don't ever use special characters in your DB's users password!!

I have been troubleshooting a migration from mariadbd to pgsql for several hours, until I tried changing my password, which, weirdly enough, was working to connect roundcube but gave errors with pgloader. Once I successfully migrated using the same password with those special characters, roundcube wouldn't connect with pgsql, so I made another fighting round! Finally changed my pgsql password to some letters and numbers only and BAM!, it worked.

Then I stopped mariadbd and disabled the service; now I have more than 200MB RAM freed¹.

¹ See previous post.

I was enabling Exim on my IONOS VPS to deliver email through a smarthost and encountered the error message in this post's title (unable to send to Gmail users.. It's always them!)

After fiddling a while with DMARK and SPF I reconfigured Exim itself to rewrite sender address, so that emails coming from "spacenest.it" (IONOS domain) were sent as coming from "woodpeckersnest.eu", the smarthost and real email server.

Everything is done via this command:

# dpkg-reconfigure exim4-config

And the resulting configuration in /etc/exim4/update-exim4.conf is:

dc_eximconfig_configtype='smarthost'
dc_other_hostnames='cassandra.spacenest.it;spacenest.it'
dc_local_interfaces='127.0.0.1'
dc_readhost='woodpeckersnest.eu'
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost='pandora.woodpeckersnest.space::587'
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='true'
dc_mailname_in_oh='true'
dc_localdelivery='mail_spool'

On OVH's postfix I just had to modify this line in /etc/postfix/main.cf:

mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 94.143.138.27/32

where that last IP is the IP Address of my IONOS server.
