mtg's Issues

Temporary unavailability on restart

Hey there,

After restarting the proxy it becomes unavailable for a couple of minutes. Telegram client app sees Connecting... and not a failed connection error. I should mention that my server does have connectivity with ipv6 telegram servers only, so I assume mtg tries to connect to ipv4 servers first, which can cause the problem.

Some time in the past mtg had MTG_USE_IPV6 environment variable option and everything was fine, btw.

Public IP detection is broken

IP [my ipv6] is not IPv4

Public IP detection is broken because DNS records of v4.ifconfig.co/v6.ifconfig.co both contains IPv4 and IPv6 addresses now:

$ host v4.ifconfig.co 1.1.1.1
Using domain server:
Name: 1.1.1.1
Address: 1.1.1.1#53
Aliases:

v4.ifconfig.co has address 104.28.3.88
v4.ifconfig.co has address 104.28.2.88
v4.ifconfig.co has IPv6 address 2400:cb00:2048:1::681c:358
v4.ifconfig.co has IPv6 address 2400:cb00:2048:1::681c:258
$ host v6.ifconfig.co 1.1.1.1
Using domain server:

Aliases:

Use sync.Pool

We allocate/deallocate memory constantly. It makes sense to use pools here

"Cannot pump sockets" in log

Hello!
Works fine, but the stderr log is full of messages "Cannot pump sockets", "Cannot read stream ciphered data".
Run it under CentOS 7 without docker in secret only mode at VPS based in England (log in verbose mode). Tried both to download ready to run file at "Releases" and build it ("Master" branch) - issue exists in both cases.

adtag problems

Добрый день!
При попытке запуска в докере с указанием adtag в лог валится ошибка:
{"level":"error","ts":1549551762.0736535,"logger":"main","msg":"Cannot initialize server connection","connection_id":"0da214ef-e6db-40d9-a66c-f22152d2f272","error":"Cannot handshake telegram: Cannot read RPC handshake response: Cannot read frame padding: Cannot read from socket: EOF","errorVerbose":"EOF\ngithub.com/9seconds/mtg/wrappers/blockcipher.go:37: Cannot read from socket\ngithub.com/9seconds/mtg/wrappers/mtproto_frame.go:52: Cannot read frame padding\ngithub.com/9seconds/mtg/telegram/middle.go:100: Cannot read RPC handshake response\ngithub.com/9seconds/mtg/proxy/proxy.go:118: Cannot handshake telegram"}
Клиенты при этом не подключаются.
Запускать пытался вот так:
docker run --name mtg-latest --restart=unless-stopped -p 8888:3128 -p 3129:3129 -d nineseconds/mtg:latest -s <ddsecret> <adtag>
При запуске без adtag все прекрасно работает. Пробовал на stable и latest.
Может быть опять какие-то изменения в API, как этом issue?

Enforce secure mode

Seems like RKN now banning proxies based on protocol fingerprint.
Iran was fast at figuring it out: TelegramMessenger/MTProxy#35
Secure mode with random padding helps (at least for now)
Might be good idea to set secure mode by default and allow disabling it via ENV/config.

обновление с сохранением секрета

а как правильно докер обновлять, я каждый раз секрет везде переставляю, наверно можно как-то по феншую делать, а то если несколько устройств менять на каждом утомительно
запускаю я его в secure mode на 443 порту вот так:
docker run --name mtg --restart=always -p 443:443 -p 3129:3129 -d nineseconds/mtg:latest dd$(openssl rand -hex 16) --secure-only --public-ipv4 ххх.xxx.xxx.xxх --bind-port 443
где ххх - ip адрес vps'ки
в документации этот вопрос вроде не освещён

How to change port&Stat_port in One-line runner ?

Just after 2 weeks running，the GFW block default port 3128 on my vps. Now cilent can't access the proxy unless I connect it with Shadowsocks.So I try to restart mtp from other ports.

Config file

Hello, is it possible to implement config file support, so i can launch it with something like

mtg -c /etc/mtg.conf

Right now i'm using systemd with EnvironmentFile, it's kind of ok but not the cleanest way for sure.

Process dead

Centos 6.10
mtg -p 443 -b 0.0.0.0 ...
The process always dies, for no reason, and it will be like this in a while.

Multiple ports

Are there any ways to listen on multiple ports? If not, than let is be feature request.

[feature request] add a param to support run as daemon

--version reports incorrect version

рандомизация в хендшейке

тут в соседней репе запилили рандомизацию в хендшейке, если я не обосрался и правильно понял) хотелось бы и тут такое видеть, очень уж прокся хорошая alexbers/mtprotoproxy@4cae629

Не подключается клиент при добавлении префикса dd

Добрый день!

mtg запущен вот так:
docker run --name mtg --restart=unless-stopped -p 8443:3128 -p 127.0.0.1:3129:3129 -d nineseconds/mtg -a 8443 <pass_here>

При добавлении в клиент префикса dd к ключу, клиент перестает соединяться с прокси. В чем может быть дело? Промежуточных прокси нет. Клиенты десктоп и мобильный, версии последние.

Согласно ридми это вррде бы(?) должно работать штатно.

Cannot start with adtag at all, without it works with some warns

Without adtag works but with erros in log:

My VPS is under NAT so I provide port, local and public addressed. I use precompiled binary from Releases.

hi matser
how can i fix it?

Why would it cause error when using ADTag ?

My command line parameters :

./mtg-freebsd-amd64 -b 0.0.0.0 -p 5258 -s ddMY_KEY MY_ADTAG
{
  "ipv4": {
    "tg_url": "tg://proxy?port=5258&secret=ddMY_KEY&server=1.70.171.49",
    "tme_url": "https://t.me/proxy?port=5258&secret=ddMY_KEY&server=1.70.171.49",
    "tg_qrcode": "https://api.qrserver.com/v1/create-qr-code?data=tg%3A%2F%2Fproxy%3Fport%3D5258%26secret%3DddMY_KEY%26server%3D1.70.171.49&format=svg&qzone=4",

  },

    "tme_url": "",
    "tg_qrcode": "",
    "tme_qrcode": ""
  },
  "secret_for_mtproxybot": "MY_KEY"
}

If I use the command without the Adtag , the proxy run well and all my client could connect through the mtg proxy server . But , if I run the command with the Adtag , I got the bellow errors :

{"level":"error","ts":1555787930.6312413,"logger":"main","msg":"Cannot initialize server connection","connection_id":"f9f96d1c-ad40-46dc-93ce-86257d9485f5","error":"Cannot handshake telegram: Cannot read RPC handshake response: Cannot read frame padding: Cannot read from socket: EOF","errorVerbose":"EOF\n/home/vagrant/safe/go/src/github.com/9seconds/mtg/wrappers/blockcipher.go:37: Cannot read from socket\n/home/vagrant/safe/go/src/github.com/9seconds/mtg/wrappers/mtproto_frame.go:52: Cannot read frame padding\n/home/vagrant/safe/go/src/github.com/9seconds/mtg/telegram/middle.go:100: Cannot read RPC handshake response\n/home/vagrant/safe/go/src/github.com/9seconds/mtg/proxy/proxy.go:118: Cannot handshake telegram"}

in the issue #65 https://github.com/9seconds/mtg/issues/65 , the reason was caused by time sync , but I checked my time , it was all right and I run NTP as background service.

So ,how could I resolve the problem ?

my system is FreeBSD 12.0 .

can't run docker exec -ti mtg "anything"

I read the Dockerfile and I know it's alpine but I can't even docker exec -ti mtg cat something or `docker exec -ti mtg apk add' something or run bash or anything.

What is preventing me from doing so?

Multi-secrets mode

I think it's a good idea to implement a multi-secrets mode. Although you have an opinion that one secret is enough there are a lot of situations when such mode would be useful. For example: private proxy for corporate use, each department has individual secret so if a secret leaked out, it's easier to change it for several users than for all corporation. This mode should be optional and must be disabled by default.

Connection multiplexing

Right now we establish 1:1 connections to Telegram even in case of middle proxies which supports multiplexing. The idea is to try to multiplex M clients to N telegram connections. In that case we will have M*N connections instead of M^2.

Periodic verification of time drift

If a proxy works in promoted channel mode then it is crucial to have time synchronized. Unfortunately, almost everyone (even I personally) had a problem with drifted time so we need to notify users somehow on that.

From RPC protocol I would say that time drift has to be less than 1 second.

How does the NAT server start the proxy?

Network card IP: 10.0.0.4
Public IP: 1.1.1.1 (hypothetical)
Port: 443
How to write the proxy startup parameters?
Help me, thank you~

Log config

Apparently, it is quite hard to investigate the problems if mtg does not log configuration

Export stats

I cannot manage all known monitoring systems available so we need to support either collectd or statsd. All these tools support export to Prometheus, Graphite etc so I think it makes sense to export to those aggregators first.

Not connected

What is wrong？how to fix it?

Humanize statistics

Even if we have clear statistics some numbers are not easily readable by humans (iterm2 helps but not everyone has it). Let's use go-humanize or something like that for marshaling such items.

Outgoing IP address

Как заставить устанавливать исходящие соединения с нужного адреса (интерфейса)?
У сервера 2 провайдера: один блокирует телеграм, второй нет. Настроен source routing.
Обычно достаточно настроить SRC ip адрес (например tcp_outgoing_adress в squid). Ни -b ни -4 не помогают, трафик всегда выходит через default gateway, с его src ip.

Egress traffic and speed

Hello. Is it okay that egress and ingress traffic and speed are almost constantly equal?

Rework stats

I do not like the mess I did there. I need to sit and rework the whole module, to avoid global locks in statsd client.

Prometheus integration

Statsd is fine but people are asking to have a native Prometheus integration without interim statsd service.

IP адрес

Добрый день
Возможно ли чтобы ip адрес клиента не отправлялся на сервер телеграм. Чтобы все клиенты представлялись ip адресом сервера mtprotoproxy. Если не правильно выразился пожалуйста поправьте.

Async stats

Current stats implementation is blocking. Even if we use atomic. Let's go OTP way and create goroutines for updating stats.

Passing domain with DNS check to make beautiful links at stats page

Well, of course it's just enchantment, so not critical, but what do you think about it?

Automatic configuration reload (no need for restarts once per day)

have this feature?

What is the secure mode?

Is there a spec for the secure mode (with tag '0xdd')? What's the difference between this one and the abridged mode?

dd-secrets are printed incorrectly in URLs

If the user provides dd-secret, then mtg returns URLs without that prefix

How to use ADTag with docker one-line runner code????????

So as the title shows I'm using the docker image and the one-line runner code you've provided to start my proxy:
$ docker run --name mtg --restart=unless-stopped -p 3128:3128 -p 3129:3129 -d nineseconds/mtg:stable my-defined-secret
in this case the proxy starts with absolutely no problems.
The problem is that you haven't provided any information about how to implement adtag in this one-line runner code.
I tried to add my Adtag to the end of the code but then the the proxy server wouldn't start at all.
$ docker run --name mtg --restart=unless-stopped -p 3128:3128 -p 3129:3129 -d nineseconds/mtg:stable my-defined-secret my-adtag

log file:
mtg-error-log.txt

so can you please illustrate the way to implement adtag?

Avoid hardcoded proxies / Promoted channels

If we use Telegram API, we do not need to have all these hardcodes + now it is clear why do we need negative DCs

$ curl -s https://core.telegram.org/getProxyConfig -H "Accept: text/plain" --compressed

Unfortunately usage of force probability is totally unclear because this API call is not public: https://core.telegram.org/methods

Cannot initialize client connection

Sometimes I get in logs:

{"level":"error","ts":1558105435.3307085,"logger":"main","msg":"Cannot initialize client connection","connection_id":"f4cb4c45-xxxx-xxxx-xxxx-xxxx6eccxxxx","error":"Cannot extract frame: Cannot extract obfuscated header: read tcp xx.xx.xx.xx:8443->88.232.168.38:19552: i/o timeout","errorVerbose":"read tcp xx.xx.xx.xx:8443->88.232.168.38:19552: i/o timeout\n/root/mtg/obfuscated2/frame.go:87: Cannot extract obfuscated header\n/root/mtg/client/direct.go:38: Cannot extract frame"}

Also the interesting thing that 88.232.168.38 IP is the TurkTelekom. But I haven't any connections with Turkish networks. Maybe these are DPI probes from the Turkey?

UPD: Another one error from the log without any IP's:

{"level":"error","ts":1558105659.805035,"logger":"main","msg":"Cannot initialize client connection","connection_id":"d4fa3c04-xxxx-xxxx-xxxx-xxxx6b3bxxxx","error":"Cannot extract frame: Cannot extract obfuscated header: EOF","errorVerbose":"EOF\n/root/mtg/obfuscated2/frame.go:87: Cannot extract obfuscated header\n/root/mtg/client/direct.go:38: Cannot extract frame"}

Typo in README or realization mistake?

Official MTProxy bot accepts only 16 char hex. We can't just prepend dd, it will already 18 chars.

Base cleanup

Well, it is time to make a general cleanup and simplify the structure of the application. The initial version was done with another idea in mind and now looks awkward and clunky.
