- <h1>Disillusioned with onion addresses</h1>
- <p>Day 00365: Sunday, 2016 March 06</p>
- </header>
- <p>
- A thought just occurred to me.
- I no longer need to avoid mentioning <a href="ircs://sbuk7aqcxkoyipwv.onion:49152/">freenode</a> entirely when I write about things that have happened there.
- I just need to be sure to use the link to my own forwarding onion address when making such mentions.
- I still can't use this onion address to connect, as it would be identical to not using <a href="apt:tor"><abbr title="The Onion Router">Tor</abbr></a> to connect at all, but other people can without struggling with freenode's incomplete <abbr title="The Onion Router">Tor</abbr> blocks.
- Also, removed my relay to IRC2P, as it only serves to distract from <a href="https://opalrwf4mzmlfmag.onion/">wowaname</a>'s relay, and instead decided to add as many <abbr title="The Onion Router">Tor</abbr>-blocking networks as I know of before being asked.
- They might be useful to someone, but someone may be too timid to ask.
- I know I would be.
- Each day, the plan was to try to add at least one <abbr title="Internet Relay Chat">IRC</abbr> network that's present in the default HexChat server list, until I reach the end of the list.
- I've uninstalled <abbr title="Invisible Internet Project">I2P</abbr> from the server as well, as it no longer serves a purpose on that machine.
- </p>
- <p>
- I started testing <abbr title="Internet Relay Chat">IRC</abbr> servers and adding them to both my <a href="file:///etc/tor/torrc">torrc file</a> and my <abbr title="Extensible Hypertext Markup Language">XHTML</abbr> list of port that are forwarded, but I quickly found keeping them in sync to be bothersome.
- To fix this, I built a function that could parse a hidden service block from a <abbr title="The Onion Router">Tor</abbr> configuration file and format it as the list that I was after.
- I needed to be able to tell the parser which <abbr title="Uniform Resource Identifier">URI</abbr> scheme to use for a given item (<code>ircs:</code> or <code>irc:</code>), as well as make my parser generic enough to handle other use cases, so I included a comment syntax that tells it what scheme to use.
- Making it more generic also required that I remove some <abbr title="Internet Relay Chat">IRC</abbr>-specific information, but I have to reluctantly admit that the result looks a lot cleaner.
- </p>
- <p>
- That ended up being in vain though.
- I found a couple issues in <abbr title="The Onion Router">Tor</abbr> that prevent me from forwarding as many ports as I would like to.
- The first problem is that some of the domain names I'm trying to forward to are supposedly unparseable, though I can't see anything wrong with the four domains that cause the issue.
- This error shows up in the error log: <q>Mar 06 21:56:58.930 [warn] Unparseable address in hidden service port configuration.</q>.
- After commenting out the offensive lines, I run into a bug: <q>*** Error in `tor': free(): invalid pointer: 0x00007fde87a055c0 ***</q>.
- This pointer error only happens if I forward several ports, and even then, there isn't stable number of forwarded ports.
- With few enough ports forwarded, the pointer error never occurs, and with enough forwarded, it always occurs.
- However, somewhere in the middle, the error only sometimes occurs.
- I can start <abbr title="The Onion Router">Tor</abbr>, it'll shut down because of that error, then I'll start it a second time and there'll be no problems.
- The only option that i can see is to comment out all the lines that haven't been requested and go back to only forwarding ports on demand.
- That way, I have the ports to spare when a new request is made and I'm not wasting ports on services that people aren't even using.
- This experience has left me a bit disillusioned with onion addresses.
- If I can't even make use of all my ports like can be done with a <abbr title="Domain Name System">DNS</abbr> address, this really cuts down on their usefulness.
- I imagine this limitation applies to the sum total of ports forwarded by all onion addresses used by a given <abbr title="The Onion Router">Tor</abbr> instance, especially because it's caused by an error, so setting up extra hidden services wouldn't likely even help.

- On <a href="ircs://kitsune6uv4dtdve.onion:6697/%23Volatile">#Volatile</a>, z showed us an awesome website that is working to <a href="https://sci-hub.io/">free knowledge</a> from the clutches of those that would hide it behind pay walls.
- I'm not sure how they operate, but it's wonderful to see such work being done.
- </p>
- <p>
- We went over to my mother's school to help her only to find out that she didn't want or need any help.
- So what was the point? We were there for three hours with nothing to do.
- Next time, I'm bringing my laptop just in cast this sort of thing happens again.
- I could have been doing something productive with my time.
