wget2 stopped working with proxychains-ng (wget/curl still work)

[koedx]

I am trying to understand why wget2 fails to connect when being run through proxychains-ng. Prior versions of wget2 (& current versions of curl & wget) work as expected.

Running proxychains4 wget2 -d --no-dns-cache --no-local-db --no-check-certificate --progress=none -O - "http://google.com" produces:

Failed to connect: General error

wget2 acquires the "dummy" ip from proxychains-ng (the 224.x.x x address) as expected (the "has" output above). At this point things seem to go wrong with wget2 (wget or curl connect to that ip & successfully download the requested page; wget2 always fails... I am using google in the posted example, but the issue exists no matter what url I attempt to connect to).

When I use wget2 w/o proxychains, after the provided host url is resolved to an IP ("has" x.x.x.x), wget2 connects to said ip (& outputs "try" x.x.x.x to indicate this).

Why isn't wget2 trying to connect to the provided ip when invoked thru proxychains-ng??

Any guidance in troubleshooting this issue would be much appreciated 🙏

Just a wild guess, try it with --no-tcp-fastopen. Because wget2 tries to connect to that IP and sees this General error. On the other hand side, TFO didn't change in a long time.

Btw, what version of wget2 are you using?

[rockdaboot]

Maybe you can help me to reproduce. Currently, proxychain4 on Debian testing doesn't seem to work. I tried a bunch of proxies, adding with http ip port to /etc/proxychains4.conf.

All I ever get is a timeout

[proxychains] Strict chain  ...  <ip>:<port>  ...  timeout

wget2 -V:

GNU Wget2 2.1.0 - multithreaded metalink/file/website downloader

+digest +https +ssl/gnutls +ipv6 +iri +large-file -nls -ntlm -opie -psl -hsts +iconv +idn2 +zlib -lzma +brotlidec +zstd -bzip2 -lzip +http2 +gpgme

I tried running w/ --no-tcp-fast-open & the general error persists.

Regarding proxychains4 issues you mention, the "original" proxychains4 (although still in the repos) is unmaintained. The maintained version/package should be installed via apt-get proxychains-ng (v. 4.16, the GitHub repo for that package is linked below). Is this the proxychains4 you are running? (if not, installing the -ng package should address the timeout issues you experienced). I can confirm that the -ng package proxifies current versions of curl & wget w/o issue (for me).
