Un naufragio personal

Tor

He escrito este email a un amigo sobre cómo configurar Tor para el servicio SSH en clientes y servidores Linux:

[...]

Respecto al cliente (azazel, portátil con Ubuntu): instalar tor y ya está. Desde ese momento corre como un proceso que monta un túnel SOCKS5 en el puerto 9050. Nada más montarlo yo ya puedo hacer:

ssh angel@samael.triptico.com -o ProxyCommand="nc -X 5 -x localhost:9050 %h %p"

Esto lo que hace es abrir una conexión normal ssh pero a través de las múltiples capas de cebolla del Tor, haciéndolo súper-seguro, intrazable y bla bla bla. Es interesante esto:

Last login: Fri Mar 13 08:52:21 2020 from 185.220.103.243

Esa IP no es la mía, sino la de uno de los nodos de salida del Tor. Todo esto ya funciona sin haber instalado aún Tor en samael.triptico.com.

Para un servidor (lucifer, servidor casero con Debian sin puertos abiertos desde el router): instalar tor y abrir un «Tor Hidden Service» añadiendo lo siguiente a /etc/tor/torrc:

HiddenServiceDir /var/lib/tor/ssh/
HiddenServicePort 1234 127.0.0.1:1234

Tras reiniciar tor (1234 es el puerto en el que corre mi SSH) te crea un servicio oculto, lo ha configurado y se lo ha notificado a la red Tor. El contenido de /var/lib/tor/ssh/hostname es:

tlnm26rl4fskwzzpxzvj25slznioajxv4afi2yb6a4fjkceraguvvaqo.onion

Mola, ¿eh? (apunta, que te lo dicto). La magia es que eso ya es accesible desde el mundo exterior con algún cliente que tenga instalado Tor:

ssh tlnm26rl4fskwzzpxzvj25slznioajxv4afi2yb6a4fjkceraguvvaqo.onion -p 1234 -o ProxyCommand="nc -X 5 -x localhost:9050 %h %p"

Aunque mola escribir eso todo el tiempo lo propio es configurarlo (tanto el host como el ProxyCommand) en ~/.ssh/config.

El lastlog te mostrará que la conexión ha ocurrido desde 127.0.0.1 (desde el punto de vista del servidor todo llega desde el túnel local).

Ojo a una cosa: la línea de comando del nc es para el de openbsd. Por alguna razón, en Ubuntu tengo el de openbsd pero en Debian el tradicional. He instalado netcat-openbsd en Debian para que todo sea consistente.

Tor proporciona un servicio para saber algo más sobre los «Exit Nodes» en el url https://metrics.torproject.org/rs.html#search/IP_EN_TU_LOG.

Espero que te sirva de ayuda.

Un abrazo,
Ángel

HOWTO compact an Virtualbox disk

In this entry I explain how to compact the Virtualbox hard disk of a virtualized MS Windows 7 running inside a Linux host.

Steps:

1. Run the MS Windows virtual machine and execute the Disk Defragmentation tool. Wait for it to finish.

2. Also from inside Windows, download a command-line program named sdelete from Microsoft (search for it). Run the following command from a console:

sdelete c: -z

This tool supposedly fills with zeroes the full filesystem. It takes a while. Once it finishes, close Windows and exit the Virtualbox GUI.

3. Open a Linux console and move to the directory where your virtual machine files are stored.

4a. If your virtual disk is already in vdi format, run the following command:

vboxmanage modifyhd windows_7-disk001.vdi --compact

4b. Instead, if you need to convert the virtual disk from vmdk to vdi, run the following command:

vboxmanage clonehd --format vdi windows_7-disk001.vmdk windows_7-disk001.vdi

Wait for it to finish, open the Virtualbox GUI, select the virtual machine, click on setup, go to storage, select the current vmdk file, click on a little icon resembling a hard disk to the right of the file, click on the virtual hard disk change option and select the new vdi file.

Adventures in Unicode's math plane

The Unicode charset has a complete plane (a subset of codepoints) dedicated to the humungous plethora of symbols used in math formula and definitions. For some reason, the creators felt that re-defining the usual latin characters in varios stylings was a necessity. I won't argue on that.

We can benefit from this odd inclusion to use special text effects in places where it's not possible, e.g. social networks. So, given that we have this text snippet:

From George Orwell's 1984:

He gazed up at the enormous face. Forty years it had taken him to learn
what kind of smile was hidden beneath the dark moustache. O cruel, needless
misunderstanding! O stubborn, self-willed exile from the loving breast! Two
gin-scented tears trickled down the sides of his nose. But it was all
right, everything was all right, the struggle was finished. He had won the
victory over himself. He loved Big Brother.

We can play with several styles. For example, using bold serif symbols:

𝐅𝐫𝐨𝐦 𝐆𝐞𝐨𝐫𝐠𝐞 𝐎𝐫𝐰𝐞𝐥𝐥'𝐬 𝟏𝟗𝟖𝟒:

𝐇𝐞 𝐠𝐚𝐳𝐞𝐝 𝐮𝐩 𝐚𝐭 𝐭𝐡𝐞 𝐞𝐧𝐨𝐫𝐦𝐨𝐮𝐬 𝐟𝐚𝐜𝐞. 𝐅𝐨𝐫𝐭𝐲 𝐲𝐞𝐚𝐫𝐬 𝐢𝐭 𝐡𝐚𝐝 𝐭𝐚𝐤𝐞𝐧 𝐡𝐢𝐦 𝐭𝐨 𝐥𝐞𝐚𝐫𝐧 𝐰𝐡𝐚𝐭 𝐤𝐢𝐧𝐝 𝐨𝐟 𝐬𝐦𝐢𝐥𝐞 𝐰𝐚𝐬 𝐡𝐢𝐝𝐝𝐞𝐧 𝐛𝐞𝐧𝐞𝐚𝐭𝐡 𝐭𝐡𝐞 𝐝𝐚𝐫𝐤 𝐦𝐨𝐮𝐬𝐭𝐚𝐜𝐡𝐞. 𝐎 𝐜𝐫𝐮𝐞𝐥, 𝐧𝐞𝐞𝐝𝐥𝐞𝐬𝐬 𝐦𝐢𝐬𝐮𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠!

𝐇𝐞 𝐡𝐚𝐝 𝐰𝐨𝐧 𝐭𝐡𝐞 𝐯𝐢𝐜𝐭𝐨𝐫𝐲 𝐨𝐯𝐞𝐫 𝐡𝐢𝐦𝐬𝐞𝐥𝐟. 𝐇𝐞 𝐥𝐨𝐯𝐞𝐝 𝐁𝐢𝐠 𝐁𝐫𝐨𝐭𝐡𝐞𝐫.

Or serif italic:

Please take note that what you see is completely dependent on the fonts you have installed in your system. For example, on my Ubuntu 19.10 I don't see the h letter. I have no clue on why (I also don't give a damn).

There is even a bold+italic set of serif characters:

𝑭𝒓𝒐𝒎 𝑮𝒆𝒐𝒓𝒈𝒆 𝑶𝒓𝒘𝒆𝒍𝒍'𝒔 1984:

𝑯𝒆 𝒉𝒂𝒅 𝒘𝒐𝒏 𝒕𝒉𝒆 𝒗𝒊𝒄𝒕𝒐𝒓𝒚 𝒐𝒗𝒆𝒓 𝒉𝒊𝒎𝒔𝒆𝒍𝒇. 𝑯𝒆 𝒍𝒐𝒗𝒆𝒅 𝑩𝒊𝒈 𝑩𝒓𝒐𝒕𝒉𝒆𝒓.

Isn't it ugly? Some styles have numerals and other don't. Watch out for "double-struck" characters:

I need to finish this post with 𝖚𝖓𝖉 𝖉𝖆𝖘 𝖎𝖘𝖙 𝖆𝖑𝖑𝖊𝖘.

Relevo generacional

Frente a mí hay un chico y una chica. Su conversación es enérgica y a veces bronca; puedo oírlos por encima de la banda sonora de ruido marrón que uso para leer en los bares. Él es hermoso, su torso está bien formado y dobla su brazo expuesto de forma estudiada, sus músculos y sus vasos sanguíneos se marcan como los de una estatua. Ella es vehemente en su discurso, de nariz grande, con una complexión también deslumbrante, el negro pelo recogido en una coleta de caballo como un torrente y unas pantorrillas poderosas que podrían reventar sus pantalones de deporte.

No usan giros idiomáticos ni sutilezas; son tan verdaderos que no las necesitan. Dominan la escena, demoledores y similares a un corrimiento de tierras; un tipo calvo y gordo sentado a mi lado, quizá algo más joven que yo, simula consultar su teléfono móvil mientras intenta no perderse ni un instante de esta demostración única.

Ellos no son conscientes de que han venido aquí a sustituirme. Son mi relevo, están aquí para reclamar los dominios que no he sabido defender. Yo, una vez más, me siento viejo, consumidor de unos recursos a los que apenas tengo derecho, listo para ser olvidado.

En la calle ladra un perro y zumban los coches.

Is anybody out there?

Today I realized that I haven't taken a look at this site's log for a very long time. I disappeared from Google's first page some years ago (and, consequently, from the Internet); suddenly I wondered if somebody ever vists this place. I don't run any log analyzer, so I located yesterday's nginx log and made a raw count:

angel@samael:~$ wc -l /var/log/nginx/triptico-access.log.1
2863 /var/log/nginx/triptico-access.log.1

So there were 2863 queries served by the httpd process on February 4th. But not so long I added ActivityPub support to the software that runs Triptico; I guessed that a non-small amount of these queries are probably Fediverse pings, spam tries and other useless crap, so I rewrote the line count to:

angel@samael:~$ grep -v mastopeek /var/log/nginx/triptico-access.log.1 | \
grep -v fediverse | grep -v GabSocial | grep -v Mastodon | wc -l
2097

Well, that was a trim. But what about the bots? I remember Bing behaving like an asshole some time ago by hammering my site (I even denied it access for a while). Let's ignore it and another fucker I knew by name:

angel@samael:~$ grep -v mastopeek /var/log/nginx/triptico-access.log.1 | \
grep -v fediverse | grep -v GabSocial | grep -v Mastodon | \
grep -v bingbot | grep -v Googlebot | wc -l
1763

Bang! How many other non-humans come here? I took a look at the file with dismay; what the fuck. There are a trillion bots lurking here! I started cropping:

angel@samael:~$ grep -v mastopeek /var/log/nginx/triptico-access.log.1 | \
grep -v fediverse | grep -v GabSocial | grep -v Mastodon | \
grep -v bingbot | grep -v Googlebot | grep -v YandexBot | grep -v Sogou | \
grep -v magpie-crawler | wc -l
1622

There are more!

angel@samael:~$ grep -v mastopeek /var/log/nginx/triptico-access.log.1 | \
grep -v fediverse | grep -v GabSocial | grep -v Mastodon | \
grep -v bingbot | grep -v Googlebot | grep -v YandexBot | grep -v Sogou | \
grep -v magpie-crawler | grep -v Applebot | grep -v SemrushBot | \
grep -v Nimbostratus-Bot | grep -v RU_Bot | grep -v MojeekBot | \
grep -v 360Spider | wc -l
1363

I learned that there are software with lame names like Applebot and Nimbostratus-Bot (it's some cloud-related crap, how original). Are there more? Sure. Though not self-identifying as a bot with a reasonable User-Agent, something asked for /robots.txt many times, and so that can be deleted as well:

angel@samael:~$ grep -v mastopeek /var/log/nginx/triptico-access.log.1 | \
grep -v fediverse | grep -v GabSocial | grep -v Mastodon | \
grep -v bingbot | grep -v Googlebot | grep -v YandexBot | grep -v Sogou | \
grep -v magpie-crawler | grep -v Applebot | grep -v SemrushBot | \
grep -v Nimbostratus-Bot | grep -v RU_Bot | grep -v MojeekBot | \
grep -v 360Spider | grep -v '/robots.txt' | wc -l
1205

Wait, more bots!

angel@samael:~$ grep -v mastopeek /var/log/nginx/triptico-access.log.1 | \
grep -v fediverse | grep -v GabSocial | grep -v Mastodon | \
grep -v bingbot | grep -v Googlebot | grep -v YandexBot | grep -v Sogou | \
grep -v magpie-crawler | grep -v Applebot | grep -v SemrushBot | \
grep -v Nimbostratus-Bot | grep -v RU_Bot | grep -v MojeekBot | \
grep -v 360Spider | grep -v '/robots.txt' | grep -v ZoominfoBot | \
grep -v AhrefsBot | grep -v SeznamBot | grep -v DotBot | \
grep -v Barkrowler | grep -v MixnodeCache | grep -v repology-linkchecker | \
grep -v Linespider | grep -v VelenPublicWebCrawler | grep -v linkfluence | \
grep -v Twitterbot | wc -l
965

I know that I don't have dead links, so all 404 errors must come from non-humans (being righteous, some of them may be due to linkrot from old sites pointing here). Also I don't serve fucking PHP here (never did), so let's prune index.php queries that most probably come from script-kiddies trying to fuck with my system:

angel@samael:~$ grep -v mastopeek /var/log/nginx/triptico-access.log.1 | \
grep -v fediverse | grep -v GabSocial | grep -v Mastodon | \
grep -v bingbot | grep -v Googlebot | grep -v YandexBot | grep -v Sogou | \
grep -v magpie-crawler | grep -v Applebot | grep -v SemrushBot | \
grep -v Nimbostratus-Bot | grep -v RU_Bot | grep -v MojeekBot | \
grep -v 360Spider | grep -v '/robots.txt' | grep -v ZoominfoBot | \
grep -v AhrefsBot | grep -v SeznamBot | grep -v DotBot | \
grep -v Barkrowler | grep -v MixnodeCache | grep -v repology-linkchecker | \
grep -v Linespider | grep -v VelenPublicWebCrawler | grep -v linkfluence | \
grep -v Twitterbot | grep -v ' 404 ' | grep -v 'index.php' | wc -l
886

Some crappy software from Apple keeps asking for /favicon.ico even though I announce this site's icon as something else. Morons.

Digging more into the log file: do queries from something that identifies as facebookexternalhit count as real people? I hope they do, but how many that day?

angel@samael:~$ grep facebookexternalhit /var/log/nginx/triptico-access.log.1 | wc -l
18

Well, not many. And what about RSS/ATOM feed aggregators? Are there real human beings behind them?

angel@samael:~$ grep -E '/(atom|rss).xml' /var/log/nginx/triptico-access.log.1 | wc -l
131

Meh. Whatever. Regardless of this, I ended up with 886 queries (from the apparent 2863) that are not clearly discardable as garbage. How much can be inferred from looking at them? Well, some of them look like real human activity; for example, queries of the Minimum Profit page followed by the images of MP's screenshots seem legit (there are 14 queries for that page). On the other hand, there are bursts of activity asking for 50+ pages simulteously in the same fraction of a second from IPs in the 47.88.x.x and 47.254.x.x ranges and running some software that reports a User-Agent that mentions the Safari browser but it's obviously lying. There are at least 400 queries from this thing. I don't know what the fuck is it.

So there are a little more that 400 queries that are not easily identifyable as cruft. But what is known as a WWW visit is not the same; following the previous example, each visit to the Minimum Profit editor page results in 15 different file requests.

This is starting to get depressing so I'll end this post here.

1 de enero de 2020

Estoy sentado frente al mar. No hay nadie, todo está en calma salvo por el rumor del agua y algún graznido de gaviota. De pronto se ha formado una ola mucho más grande que el resto. No era un tsunami pero sí extrañamente alta y ruidosa, temblorosa, coronada de espuma. Al instante se ha desmoronado y todo ha seguido igual, como antes, como ahora. He mirado a mi alrededor y no ha habido ningún otro testigo de este hecho sorprendente y efímero. Eso ha tenido que significar algo. O quizá es cosa mía, quizá soy yo esperando algún tipo de señal.

Lanzamiento del satélite CHEOPS

Para aquellos a los que les gustan estas cosas: mañana día 17 de diciembre se lanza el CHEOPS, un satélite destinado a la búsqueda de exoplanetas fabricado en España por la gente increíblemente brillante de Airbus Defence & Space (de soltera, CASA Espacio) y en el que he tenido el honor de colaborar un poquito. El chisme incluye varios detalles cuquis: parece una cámara de fotos gigante con tapa de objetivo abatible y lleva clavada una chapa con 2748 dibujos de niños que fueron seleccionados en un concurso organizado por la ESA y la agencia espacial suiza.

El lanzamiento lo hará la compañía Ariane desde la Guayana Francesa y se retransmitirá en directo a las 09:30 hora española desde la web de vídeos de la ESA.

Esto es un orgullo nacional. Con suerte aparecerá en las noticias enterrado entre un montón de gilipolleces.
