LexterS999 · 2017-04-13T07:51:53Z

Still have the same problem after re-installation on pure Ubuntu 16.10 x86 kernel is 4.10

madeye · 2017-04-17T01:50:00Z

Try port 443.

LexterS999 · 2017-04-17T06:50:06Z

@madeye i did everything and tried different port's too. -U and -u too. Nothing.

madeye · 2017-04-17T06:56:12Z

When you say errors, does simple-obfs work for you? Or you are just reporting there are errors in the log?

LexterS999 · 2017-04-17T06:57:53Z

Yes obfs working and it's only in obfs log showing errors in real-time. Without obfs there is absent any error. But all mo config setup properly like in manual. And i'm using tls-obfs cause http-obfs doesnt work for me.

madeye · 2017-04-17T07:00:55Z

I don't think these errors matter. You may try enlarging the timeout of your obfs plugin by adding this option: t=3600 to both your server and client.

LexterS999 · 2017-04-17T07:02:32Z

Yes i did that too. Doesnt help.

madeye · 2017-04-17T07:04:29Z

Yes obfs working and it's only in obfs log showing errors in real-time

You may add vto your plugin opts and post the full log here.

madeye · 2017-04-17T07:13:47Z

I only see one ERROR in your log, which also looks irrelevant.

LexterS999 · 2017-04-17T07:14:46Z

One error cause i'm cut other.. it's just repeating every few seconds

madeye · 2017-04-17T07:17:10Z

it's just repeating every few seconds

If so, just ignore them. It means you're visiting some website that is not reachable by your server. To figure out what the site is, you could add -v to your command line.

LexterS999 · 2017-04-17T07:19:56Z

But it wasnt before. And this error doesnt appear without obfs-plugin. Also all sites working well and fast. No one of them is broke. I did that -v So now what to do?

madeye · 2017-04-17T07:21:57Z

Just post you FULL log here with -v.

LexterS999 · 2017-04-17T07:23:22Z

Here is it:

The same. Cut repeated [simple-obfs] ERROR: getpeername: Transport endpoint is not connected

madeye · 2017-04-17T07:29:01Z

Obviously, you didn't add -v to your command line, as there is no "verbose" log here.

LexterS999 · 2017-04-17T07:30:06Z

Yes i did
ss-server -c /etc/shadowsocks-libev/config.json -U -v

madeye · 2017-04-17T07:31:42Z

You should not add -U to your command line. It means you only forward UDP traffic...

LexterS999 · 2017-04-17T07:33:04Z

But ss-server -c /etc/shadowsocks-libev/config.json -u -v show's almost the same error. Time to time.

madeye · 2017-04-17T07:36:55Z

According to your latest log, everything works well. Just ignore any "reset" in your log. They are expected.

LexterS999 · 2017-04-17T07:41:02Z

Just worried that something strange happened with my config setup but if it's ok... Anyway errors means that something wrong. Maybe in code? And what's better to setup if i wanna use torrent downloading? -U or -u?

madeye · 2017-04-17T07:43:00Z

It's not a real ERROR. Actually, shadowsocks always closes connections with TCP reset, which is expected.

LexterS999 · 2017-04-17T07:44:07Z

Okay then last question: what's better to setup if i wanna use torrent downloading? -U or -u?

madeye · 2017-04-17T07:45:07Z

Only -u.

LexterS999 · 2017-04-17T07:45:33Z
