Scraping: Using Proxies

Scraping: Using Proxies

Neće preko Proxy: https://www.gutegutscheine.ch/ ali ZBOG RESIDENTIAL i ni zbog čega drugog… radi mi provereno na: proxyland.io curl -I https://www.gutegutscheine.ch/

also, do “Block images” da sačuvaš bandwidth: https://github.com/puppeteer/puppeteer/blob/main/examples/block-images.js https://www.scrapehero.com/how-to-increase-web-scraping-speed-using-puppeteer/ https://github.com/puppeteer/puppeteer/issues/1913

Nije mi se bunio na screaming frog - dakle, kada “zajašiš” nije panika

A neće ni preko Puppeteer

Probam ovde: https://try-puppeteer.appspot.com/

The header that is sent with puppeteer identifies it as headless chrome, which may be the reason it is blocked so easily. Try copying the headers from your non-headless browser.

Rešeno sa USER AGENT-OM!

await page.setUserAgent(‘Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3419.0 Safari/537.36’);

Savršeni tekstovi:

Napravi da kad detektuješ headless Chrome, da vratiš sve vaučere tupave koji pokazuju na NJIHOV sajt :)

A Proxy detection?

Detektuje na osnovu header-a verovatno: X_forwarded_for Ovaj dobro detektovao: https://ip-check.net/detect-proxy.php a ovaj i nije baš: https://www.infobyip.com/detectproxy.php

Proxy services

Odlični ali preskupi:

Ali najjeftiniji je: 1. https://anonymous-proxies.net/pricing (Bucharest) unlimited, 1 proxy je $5. 5 proxyja je $25 - obedljivo najjeftinije (mesečno plaćanje) min order je $10 i sajt izgleda super 2. https://stormproxies.com/clients/signup/kqUM3vnwq?product_id_page-0[]=97-97 jer tu je unlimited bandwidth! $19.00 mesečno. za $50 je 5 proxy-ja

3. Proveri - dobar je: https://rsocks.net/mobile-proxy

Najbolji koje sam našao, da ne koštaju ruku i nogu: https://proxyland.io/ izgleda “normalno” - pay as you go cena je $50 za 20GB što je oko 13000 strana njihove težine od oko 1.5MB (iako ću tu moći dosta da uštedim) pošto imaju 431 šop, ispada da za 13000/430 = 30 puta scrape ceo sajt. To je super! i više nego dovoljno! Znači, košta me $50 mesečno da ga scrape-ujem svaki dan (samo da proverim šta je novo) https://stackoverflow.com/questions/52777757/how-to-use-proxy-in-puppeteer-and-headless-chrom

skuplji: https://www.yourprivateproxy.com/buy-residential-proxies https://astroproxy.com/#rates-block - 20GB je takođe ispalo $50 https://zenscrape.com/residential-proxies/ https://homeip.io/pricing/ https://www.ipburger.com/pricing/residential/ https://www.geosurf.com/products/residential-ips/ https://shifter.io/ https://www.proxyrack.com/unmetered-residential/ https://blazingseollc.com/proxy/faq/ - ovi nemaju residental https://www.scrapingdog.com/pricing https://www.proxy-cheap.com/pricing/residential-proxies/ https://proxyaqua.com/residential-rotating-proxies/

Easily Boost Ubuntu Network Performance by Enabling TCP BBR

HTTP proxy can only proxy HTTP (TCP) traffic whereas a SOCKS5 proxy can handle any type of traffic using either TCP or UDP. SOCKS5 proxy is more universal and can be used with more applications.

Self-hosted socks5 or shadowsocks server in a single command This is just a basic proxy, very simple to install and use. If you are interested in a more functional and complex solution, you may check out StreisandEffect/streisand

Install Dante (SOCKS5):

export PORT=22333; export PASSWORD=5whEwbHKnjcQkS; export USER=user curl https://selivan.github.io/socks.txt | sudo –preserve-env bash

Test if it’s working:

# curl -x socks5://<your_username>:<your_password>@<your_ip_server>:<your_danted_port> ifconfig.co
curl -x socks5://user:5whEwbHKnjcQkS@46.4.33.38:22333 ifconfig.co

How To Use Systemctl to Manage Systemd Services and Units

Check the config with: systemctl cat danted On any problem, check service log: journalctl -u danted

Enable specific rules

Rules

There are two sets of rules and they work at different levels. Rules prefixed with client (client pass/block) are checked first and are used to see if the client is allowed to connect to the Dante server. We will call them “client-rules”. The other rules, which we call “socks-rules”, are prefixed with socks pass/block and these rules are only checked if the client connection has been allowed by the client-rules.

Both set of rules are evaluated on a “first match is best match” basis. That means, the first rule matched for a particular client or socks request is the rule that will be used.

Limit by IP

Solving SOCKS5 & Puppeteer “no-authentication” problem is using Dante’s Limit by IP Address. Place inside /etc/danted.conf before any other socks rule:

# allow access from IP without authentication
socks pass {
  from: 46.4.33.38/32 to: 0.0.0.0/0
  log: error
  socksmethod: none
}

We must change global defaults to:

socksmethod: pam.any none

and because rules have default to global socksmethod fields, we also must change all the rest socks pass rules. It’s usually only one pass there.. Put socksmethod: pam.any there so authentication is still required for any other IP.

Test:

curl -x socks5://user:5whEwbHKnjcQkS@159.100.248.236:22333 ifconfig.co

Alive Proxy Servers for Personal Use

I need a source for reliable, currently alive proxy servers. I do use them for playing music from Last.fm, or watching TV on clicker.tv.

So, I found a quite reliable source of proxy servers: http://blog.qualityproxylist.com/
