nyx's Issues

Incorrect (?) uptime

Nyx seems to be showing me the “real" uptime of my relay, that is the time since I started it. However, since I have a dynamic address, the effective uptime (the value I see on Onionoo and in Tor logs) is not equivalent to that value. Is there any way I can see that instead?

list index out of range

I got a tor node up and running of my pi right, I installed nyx, launched it on my control port and was met with this stack trace

I was about to blow my brains out then I made this change to the log.py file

- if entry_comp[1] == 'file':
+ if entry_comp[0] == 'file':

then it worked perfectly fine with no issues, curses were a little screwed up for whatever reason but I'm not complaining.

I'm running nyx 2.1.0 from the debian repositories (installed tor-arm & nyx). Reply with any other requested information. Also if the stack trace looks a little funny I copied it by hand 👍

debian-tor permission instructions

My current invocation is:

sudo -u debian-tor nyx -s /run/tor/control

Nyx should take -u debian-tor as both a CLI & nyxrc option, and drop privs to minimum necessary so it's not running escalated.

Alternatively, the man page should give instructions on e.g. what chgrp to set on the socket (or torrc config lines, or whatever) so that it can run as the current user w/out sudo.

Nyx is not showing any inbound connections

Hi,

Running Tor 0.4.5.1-alpha here. I've installed Nyx with Python's pip3 installer.

Tor currently has around 2300 inbound and 2300 outbound connections (checked with netstat -p).

When I run nyx I don't see any inbound connections at all:
Connections (2412 outbound, 1 control)

When I switch the resolver to netstat I get this:
Connections (5130 outbound, 1 control)

I also tried shutting down the relay and restarting it but that didn't fix the issue.

Tor is build with:
./configure --disable-module-dirauth --prefix=/usr --sysconfdir=/etc --localstatedir=/var --mandir=/usr/man --libdir=/usr/lib64 --docdir=/usr/doc/tor-0.4.5.1-alpha --with-tor-user=tor --with-tor-group=tor --build=x86_64-slackware-linux

Add hostnames and geoip to connection panel

Migrated from ticket 18547.

Many releases ago Nyx showed hostnames on the connection panel, but dropped this because it leaked our connections to our DNS provider. We can still get this information, but it must be on every relay or none at all.

Turns out Onionoo already supports exactly what we want! In particular here's the query we want.

Note that Onionoo supports gzip compression and we want to take advantage since it drops the size of our replies from 1.5 MB to 432.6 KB.

For this we want a new Daemon subclass in tracker.py. This class would have a single relay_details(fingerprint) method that returns a struct with these attributes. If we meet the following two constraints then it calls Onionoo to update our cache...

We make a request for a fingerprint the cache doesn't have.
It's been over an hour since the relays_published date in our last reply (like the consensus Onionoo updates hourly, so no point in requesting more frequently).

Note that we might not want all of these geoip fields (we'll need to fiddle with the panel to see what is nice to have).

Needs more than two gigabyte RAM if running for two days

Nyx seems to have a memory leak. If it runs for a long time it will consume my whole swap. This time it ran 2 days only and needs 3GB swap and 1GB RAM of and won't close until the swap is freed or you press ctrl+c multiple times.

Text fields wider than the screeen cropped

Migrated from ticket 28334.

Nyx 2.0.4 at Linux.

The first problem exist with all options: if I select some option, then press Enter (so, start editing it), and then press ESC, all old values for the option are erased (value becomes none). This behavior confuses users, because normally ESC should keep old version of values. To my opinion, if I really need to make it none I should manually remove old values (or press ctrl+u) and then press Enter.

The second problem exist with options which have very long list of values. For example, you can consider torrc with a long list of SocksPort options or a long list of values for ExcludeNodes option. If you select such option in configuration editor (press Enter), only the first part of values' list will be shown. Other lengthy part of values list will not be printed and will not be accessible for editing (it is considered as non-existing). I guess it is related to the problem of line splitting (#28297). Since the first part of accessible values may end at any character (when end of line is reached), if I don't do anything, but just print Enter, I may get an error

Unacceptable option value: Invalid SocksPort configuration (press any key)

As nyx gives to Tor wrong option values, there are many warnings in a log file of tor itself, e.g.:

Controller gave us config lines that didn't validate: Invalid SocksPort configuration

Thus, if you accidentally press Enter on any option with too long list of values, you get trapped in inescapable situation: ESC will erase all old values, Enter will change them too (possibly with some errors). It is impossible to preserve status quo.

Nyx has glichty text if using zsh, ohmyzsh and the zshrc from kali linux with a login shell.

Always when I open nyx I see glichty text, like instead of No nyxrc loaded, No yxcr loaeda or lke this.

The worst is that there is stuff in the graphs (0;7[0;), seem to be color definers. Only happens on start. The first line is someting completely screwed up. Doesn't happen, if I try with zsh, only when using login shells (eg. tty 2...).

nyx fails to build with Python 3.11.0a2

Hi,

Fedora is testing rebuilding its packages with Python 3.11, which is expected to be released in Fedora 37 (~ 1 year), and we have found this error when running the nyx tests.

Does Nyx modify/remove/add any files to /var/lib/tor?

I'm curious if a relay with nyx would have the same /var/lib/tor directory as one without nyx? So my question is does nyx interact with this directory at all? Thanks!

A call of nyx, eg.:

however shows about 7500 connections (Alt+S -> Connections) which seems to be the sum of boths.
Netstat etc how that the command line values are right, Nyx is wrong.

Welcome page

Migrated from ticket 18708.

I've been impressed at how much Nyx users miss. Hell, I've met longtime users that didn't even know you could press left/right for additional pages. They thought Nyx had just one!

To be fair Nyx's discoverability sucks. I've tried to keep the most important information simple so it can be displayed on a single line...

m: menu, p: pause, h: page help, q: quit

But maybe we should show a one-time popup to first time Nyx users that explains how Nyx works. We could then persist a 'shown' flag in their home directory to suppress future popups.

Nothing in Connections tab

The connection tab of my relay is just empty. On the traffic page nyx shows the following error message:
[NYX_NOTICE] BUG: Unexpected exception from ConnectionTracker: "getpwnam(): name not found: 'tor'"

My relay is running in a docker container, ControlPort is correctly forwarded from the container and everything else except the connections tab also works.

FAQ webpage unavailable without javascript

Our website tries to fall back when JS is unavailable, but our FAQ is entirely missing without JS.

Without JS we can't toggle the visibility of items, but the information should be available in some form.

Distributor ID: Debian
Description:    Debian GNU/Linux 10 (buster)
Release:        10
Codename:       buster

Tor version 0.4.5.10.

User interface reads the tor version as "obsolete":

nyx - lada (Linux 4.19.0-17-amd64)         Tor 0.2.9.8 (obsolete)

Detect when ACS doesn't work

Migrated from ticket 18540.

Probably the most common annoying visual bug I've seen is broken curses ACS support. This causes us to show 'mwqqqqqqqqqqqqq' for window borders...

We can sidestep this by showing ASCII pipes instead ('+--------+'), but to do that we need to be able to detect when ACS is broken. Thus far I'm not sure how to do this - tips welcome...

Ctrl-L to redraw screen

I'm running nyx, but I had a browser process in the background before I launched it. Every so often the browser process prints stuff to its stdout, which clutters up my nyx screen in weird ways.

In normal unix terminal applications, I would type "control l", aka Ctrl-L, and it would refresh my screen, to get rid of the random stuff printed on my screen that nyx didn't intend to be there.

Does nyx support that? Should it?

The behavior I want is essentially as though I pressed right arrow and then left arrow (plus redrawing the top part too, if that doesn't also happen when I shift nyx pages)

Support for connecting to control port over ipv6

Right now the --interface option only supports connecting to ipv4 addresses - it would be nice if I could connect over ipv6 as well.

The use case is that I'm deploying Tor on https://fly.io and they connect applications together over ipv6:
https://fly.io/docs/reference/privatenetwork/

To avoid running Nyx / the control protocol over the public internet I'd like to deploy Nyx in a container which I ssh into, and that container connects to my Tor instance over ipv6.

Thanks,

Option to close circuit

Migrated from ticket 14979.

Vidalia allows that, and that's one thing we at Tails will be missing when we remove it. The main use case is debugging potentially buggy or malicious exit nodes. For example, you get an unexpected HTTPS or SSH warning, write down the info about your exit node, and close that circuit to get a fresh one and confirm your suspicions.

All help would be appreciated.

Graphs not being generated

Hi,

Upon attempting to use nyx on a Slackware system the graphs remain empty. I assume it is an dependency issue that was not caught at install time. I resolved all the dependency issues it showed during the installation by compiling Python with SQLITE support and it seems that the program is fully working, with the only exception being the graphs.

Traffic does seem to be captured as I am able to see connections.

Any idea what else I might need to install?

I also installed nyx on an openSUSE system, where immediately upon launching pretty graphs were generated.

Thanks!
Georg

nyxrc config should also allow command line options

Namely:

It already has --log as logged_events.

By default Nyx cant run without sudo on Debain

Steps I used to get it working on Debian

add CookieAuthFileGroupReadable 1 to /etc/tor/torrc
sudo usermod -aG debian-tor $USER
sudo systemctl restart tor
exit

After I logged back in and tor was successfully restarted I was able to use Nyx without sudo

Config graph_bound documentation inconsistent

https://nyx.torproject.org/#configuration says graph_bound is default max_local and options are global_max, local_max, tight

So… which is it, max_local or local_max? And to double check: max_global or global_max?

PR #27

Nyx shows 2500 inbound connections and 1500 outbound, but there's almost zero traffic.

Is it possible, that nyx shows me A LOT of connections that are + 2.1d old? All 2.1d. Why do I have so many inbound connections?
Tor uses ~8% cpu and ~500MB RAM.

I only have an average of 190KB/s! My relay has the Fast flag.

unused configuration entries: unicode_support, acs_support

Bug from potential TOR attacks?

When run nyx on macOS CLI, I was able to view the first 2 reports (connection details, node circuit infos, configs), then nyx crashes with error abort trap: 6 . is this a sign of TOR attacks? Also there was no connection details. I know there was explanations but this is fyi. TKS!
Also I just noticed that on the first report, it read 'Relaying disabled', is this normal in your opinion?

Ubuntu 18.04 - import distutils.spawn ModuleNotFoundError: No module named 'distutils.spawn'

Hi! Looking at the documentation there seems to be no mention of the dependency python3-distutils when installing nyx on Ubuntu 18.04 OS.

When installing on 18.04 one encounters an error which may look like this:

File "/usr/bin/nyx", line 11, in load_entry_point('nyx==2.0.4', 'console_scripts', 'nyx')() File "/usr/lib/python3/dist-packages/pkg_resources/init.py", line 480, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python3/dist-packages/pkg_resources/init.py", line 2693, in load_entry_point return ep.load() File "/usr/lib/python3/dist-packages/pkg_resources/init.py", line 2324, in load return self.resolve() File "/usr/lib/python3/dist-packages/pkg_resources/init.py", line 2330, in resolve module = import(self.module_name, fromlist=['name'], level=0) File "/usr/lib/python3/dist-packages/nyx/init.py", line 46, in import distutils.spawn ModuleNotFoundError: No module named 'distutils.spawn'

It would be helpful to add a small note regarding dependency on either the Github repo or at nyx.torproject.org.
I suggest a short note like this under the FAQ section at nyx.torproject.org, and specifically under the question "Does Nyx have any dependencies?":

Ubuntu 18.04 dependency:

nyx with tor service

Hello everybody,
I have a questing using nyx to monitor my tor service;
/usr/lib/systemd/system/tor.service

This service is run with sudo, when I attempt to run nyx, I get error.

❯ nyx
Unable to connect to tor. Maybe it's running without a ControlPort?

Editing /etc/tor/torrc, by adding

ControlPort 9051
CookieAuthentication 1

Then restart tor service with sudo systemctl restart tor and attempt to start nyx.
New error:

❯ nyx
We were unable to read tor's authentication cookie...

  Path: /var/run/tor/control/var/run/tor/control.authcookie
  Issue: Authentication failed: '/var/run/tor/control/var/run/tor/control.authcookie' doesn't exist

The paths above seem to be concatenated, but they do exist.

❯ ls /var/run/tor
control=  control.authcookie  socks=  tor.pid

Running sudo nyx works but, but expect this is not a good idea:

Figured you'd want to know that I've got Nyx to run natively on Windows (mostly)

Whether it'd be in the interest of the dev team, end-users, both, or neither, I've managed to get Nyx to run on Windows, thus filling a potential user demographic considering how https://nyx.torproject.org/#download states the upstream project doesn't support Windows.

The details, patch-files, and installation notes are at https://github.com/DandelionSprout/NyxForWindows, and takes the form of 2 files to overwrite a couple files from the Python pip version with, and is not a full fork or redistribution of the entire program.

I've done my utmost to ensure compliance with GPL-3.0, as verbose as that licence is.

Show streams on circuits

Migrated from ticket 5186.

Nyx should show the targets of individual streams. For example, currently nyx might show a new stream like this (spaces removed):

127.0.0.1:42051 --> 127.0.0.1:9050 UNKNOWN 0.0s (SOCKS)

Of course the destination is 127.0.0.1:9050. That's just our socksport, and it provides no new information to the nyx user. The destination should be shown as the target of the stream.

Once the stream is attached to a circuit, this binding should be shown explicitly. Note that this is not entirely trivial to do: for example, sometimes streams are reattached to different circuits (e.g. if a particular circuit does not work).

It might also be useful to indicate the status of a particular stream, e.g. "SENTRESOLVE", "SUCCEEDED", etc.

View consensus weight

Is there perhaps any way to view one’s consensus weight (preferably both the raw value and the fraction)?

Average and total not shown when terminal is < ~ 120 chars wide

The "avg/total" stats above the graph get cut off as your terminal narrows -- empirically, for me at least, they start getting chopped when the terminal is narrower than ~ 120 characters. At the resolution I normally run, good old 80 characters wide, they're not visible at all.

The old code (arm) would display these stats below the graph when it couldn't display them above. At Damian's request, I am filing a bug to politely request something like the old behavior -- or, of course, any alternative where the stats are shown for narrower terminals like mine. Thank you!

Native Windows Support

Migrated from ticket 18694.

Nyx can probably run in Cygwin, but native Windows support requires...

Curses alternative. Python has a ticket for adding Windows support but looks unlikely to get traction. Forerunner seems to be PDCurses.
Resource usage information. Stem already supports Windows connection resolution but we need to expand Nyx's tracker to retrieve cpu/memory usage on Windows too.

Maybe some other gotchas too. Windows is adding a *nyx commandline which might be interesting to keep an eye on.

nyx shows me out outbound connections from other tors

I run Tor Browser Alpha, and set it to use Snowflake. Then I run "nyx -i 9151". It shows me some circuits that start at the Snowflake bridge, but it also shows me some direct connections to random relays.

Woah! Is Tor broken? Is it connecting to these other relays as Directory Guards, and using my snowflake bridge for the 3-hop circuits? What's going on?

Then I close ricochet, which is not using Tor Browser's socksport or its controlport, and the other outbound connections on my nyx dashboard go away.

Tor can know what are my outbound connections, by "getinfo orconn-status". This is a case where using netstat picks up extraneous connections, and alarms me by telling me my Tor is using them when it isn't.

Related to issue #9 here, but it is on the client side, and it looks like a security issue until you figure out what's going on, so I'm going to file it as its own ticket and let atagar figure out how he wants to move forward.

Thanks!

nyx Error: "Unable to save configuration ([551] Unable to write configuration to disk.)"

Got this error message when I want to save (as root) the torrc after editing the config in nyx.

Link in error message leads to empty page

> user@hostname:~$ sudo -u debian-tor nyx
Python's sqlite3 module is unavailable. Unfortunately some platforms
don't bundle this with the interpreter. Please let us know at...

  https://trac.torproject.org/projects/tor/wiki/doc/nyx/bugs

I think this error happened because of heavy load on the host so probably not a problem with nyx.

But maybe the link should get removed or updated to the appropriate location because https://trac.torproject.org/projects/tor/wiki/doc/nyx/bugs leads to an empty page.
