ignoring some ports not working (no errors too)

[harshith-red]

hello, im having an issue with ignoring a port i put this in my conf file:

localnet 0.0.0.0:80/0.0.0.0

and when i run:

proxychains4 curl ifconfig.me

i get my squid server's ip address and not mine, which means that the port is being proxied. output: the file:

I also find same problem as you in version 4.15, but it don't appear in version 4.12.

I also find same problem as you in version 4.15, but it don't appear in version 4.12.

could you try to use git bisect to find the commit that broke it ?

I just tried it, and I found that the bug appeared in this commit:

(ning_base) ning@ubuntu:/usr/local/src/temp/proxychains-ng$ sudo git bisect good
50c079d4b44d6d96064fd0985306e165c2ed8285 is the first bad commit

    don't try to connect to null-routed ips

At the same time, I must point out that there is a problem with the test method of the original issue, because localnet 0.0.0.0:80/0.0.0.0 is only valid for ip instead of domain name.
I tested it according to the following method：

1. python -m http.server 2345
2. proxychains4 wget 0.0.0.0:2345

don't try to connect to null-routed ips

thanks, good find.

I tested it according to the following method

what was the config for localnet for your test ?

localnet 0.0.0.0:2345/0.0.0.0

2. proxychains4 wget 0.0.0.0:2345

i think this test is flawed too. you need to use e.g. proxychains4 wget 10.0.0.1:2345 where 10.0.0.1 is the local ip of your network adapter.

Yes.using your test method don't appear same problems. But why proxychains4 wget 0.0.0.0:2345 also work in prior version?

[rofl0r]

Yes.using your test method don't appear same problems

so, no problem at all? or if there's a problem is it what was described by OP? if so it would be helpful if you can bisect.

But why proxychains4 wget 0.0.0.0:2345 also work in prior version?

by accident. 0.0.0.0 isn't a valid routable ip.

Yeah, there won't be any problems when using proxychains4 wget 10.0.0.1:2345

Well, maybe 0.0.0.0 isn't a valid routable ip. But pycharm's official pydevd tool is used in this way. I configured localnet 0.0.0.0/0.0.0.0. In version 4.15, a connection error occurred:

[proxychains] config file found: /etc/proxychains.conf

[proxychains] DLL init: proxychains-ng 4.15-git-1-g7de7dd0
Could not connect to 0.0.0.0: 44765
Traceback (most recent call last):

In version 4.12, it work well.

But pycharm's official pydevd tool is used in this way.

and where does the 0.0.0.0 come from ? is this something you configured, or how pycharm connects by default to its services ? the latter would be surprising.

This is the default configuration of pycharm and I cannot easily change it unless I modify the source code. Thank you for your help, I don't want to continue tossing it now.
