proxychains-ng というものを見かけたので試してみます．ネットワーク関連の関数をフックして，SOCKS 4a, 5, HTTP proxy を利用できるようにします．
torsocks的な感じ．
- rofl0r/proxychains-ng: proxychains ng (new generation) – a preloader which hooks calls to sockets in dynamically linked programs and redirects it through one or more socks/http proxies. continuation of the unmaintained proxychains project. the sf.net page is currently not updated, use releases from github release page instead. 🏛️
とりあえずこんな感じで動きました
$ git clone https://github.com/rofl0r/proxychains-ng
$ cd proxychains-ng
$ ./configure && make
src/proxychains.confにtorの設定が書いてあるのでとりあえずそれで動かします．(tor daemon が動いている前提)
1回目はtimeoutに，2回目は成功．
$ ./proxychains4 -f src/proxychains.conf curl ifconfig.me/ip
:
[proxychains] Strict chain ... 127.0.0.1:9050 ... ifconfig.me:80 <--socket error or timeout!
curl: (7) Couldn't connect to server
$ ./proxychains4 -f src/proxychains.conf curl ifconfig.me/ip
:
[proxychains] Strict chain ... 127.0.0.1:9050 ... ifconfig.me:80 ... OK
158.69.192.239
torsocksでは起動しないfirefox も起動した．
$ ./proxychains4 -f src/proxychains.conf firefox
Debian package にも proxychains4 という名前であった．こっちのほうが楽ですね．
$ apt show proxychains4

Description: redirect connections through socks/http proxies (proxychains-ng)
Proxychains is a UNIX program, that hooks network-related libc functions
in dynamically linked programs via a preloaded DLL (dlsym(), LD_PRELOAD)
and redirects the connections through SOCKS4a/5 or HTTP proxies.
It supports TCP only (no UDP/ICMP etc).
.
This project, proxychains-ng, is the continuation of the unmaintained
proxychains project (known as proxychains package in Debian).
