Selenium: ERR_PROXY_CONNECTION_FAILED - selenium-webdriver

options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=%s' % proxy_list[proxytumb])
driver = webdriver.Chrome(options=options)
driver.get(url="https://lzt.market")
! Message: unknown error: net::ERR_TUNNEL_CONNECTION_FAILED
(Session info: chrome=109.0.5414.76)
I don't know what the problem is

Seems like your proxy doesn't work. Check the following:
Does the proxy require authentification? If yes, you might consider using Selenium-Profiles, since authentificated proxies aren't supported for chrome by default.
check, if your proxy is good. You can do that, for example by using curl -x "http://user:password#proxy_host:port" "http://httpbin.org/ip" or curl -x "http://user:password#proxy_host:port" "http://httpbin.org/ip".

In Selenium webdriver, for remote Firefox how to use OSS bridge instead of w3c bridge for handshaking

I am using selenoid for remote browser testing in ruby.
In that I am using 'selenium-webdriver', 'capybara', 'rspec' for automation. And I am using attach_file method for uploading file to browser
I want to upload file on Firefox and Chrome browser but it raises error on both;
In chrome
Selenium::WebDriver::Error::UnknownCommandError: unknown command: unknown command: session/***8d32e045e3***/se/file
In firefox
unexpected token at 'HTTP method not allowed'
So After searching I found the solution for chrome which is to set w3c option false in caps['goog:chromeOptions'] > caps['goog:chromeOptions'] = {w3c: false}
So now chrome is using OSS bridge for handshaking but I don't know how to do it in Firefox. Similar solution is not available for Firefox.
My browser capabilities are following:
if ENV['BROWSER'] == 'firefox'
caps = Selenium::WebDriver::Remote::Capabilities.new
caps['browserName'] = 'firefox'
# caps['moz:firefoxOptions'] = {w3c: false} ## It is not working
else
caps = Selenium::WebDriver::Remote::Capabilities.new
caps["browserName"] = "chrome"
caps["version"] = "81.0"
caps['goog:chromeOptions'] = {w3c: false}
end
caps["enableVNC"] = true
caps["screenResolution"] = "1280x800"
caps['sessionTimeout'] = '15m'
Capybara.register_driver :selenium do |app|
Capybara::Selenium::Driver.new(app, browser: :remote,
:desired_capabilities => caps,
:url => ENV["REMOTE_URL"] || "http://*.*.*.*:4444/wd/hub"
)
end
Capybara.configure do |config|
config.default_driver = :selenium
end
I have found the problem. There is bug in selenium server which run on java so I have to change my selenium-webdriver gem version 3.142.7 and monkey-patch.
You can find more information here about the bug and resolution.
For now I have to change my gem and monkey patch the selenium-webdriver-3.142.7\lib\selenium\webdriver\remote\w3c\commands.rb file. check for below line which is on line no 150.
upload_file: [:post, 'session/:session_id/se/file']
and update it to
upload_file: [:post, 'session/:session_id/file']
i had a similar issue with rails 7. the issue is connected with the w3c standard. the core problem is that the webdriver for chrome uses a non-w3c standard url for handling file uploads. when uploading a file, the webdriver uses the /se/file url path to upload. this path is only supported by the selenium server. subsequently, the docker image provided by selenium works fine. yet, if we use chromedriver, the upload fails. more info.
we can solve this, by forcing the webdriver to use the standard-compliant url by overriding the :upload_file key in Selenium::WebDriver::Remote::Bridge::COMMANDS. since, the initialization of this the COMMANDS constant does not happen when the module is loaded, we can override the attach_file method to make sure the constant is set correctly. here the hacky code:
module Capybara::Node::Actions
alias_method :original_attach_file, :attach_file
def attach_file(*args, **kwargs)
implement_hacky_fix_for_file_uploads_with_chromedriver
original_attach_file(*args, **kwargs)
end
def implement_hacky_fix_for_file_uploads_with_chromedriver
return if #hacky_fix_implemented
original_verbose, $VERBOSE = $VERBOSE, nil # ignore warnings
cmds = Selenium::WebDriver::Remote::Bridge::COMMANDS.dup
cmds[:upload_file] = [:post, "session/:session_id/file"]
Selenium::WebDriver::Remote::Bridge.const_set(:COMMANDS, cmds)
$VERBOSE = original_verbose
#hacky_fix_implemented = true
end
end
In Firefox images we support /session/<id>/file API by adding Selenoid binary which emulates this API instead of Geckodriver (which does not implement it).

How can we change value openSearcher=true from JAVA Code?

I am trying to insert data to SOLR using HardCommit. By default value of openSearcher=false in solrConfig.xml. I want to change openSearcher=true through JAVA code. Donot want to make change to SOLR.config.xml. Is there any way to do that??
Thanks
You should be able to do that with Config API. You could check current configuration by firing GET request at /config endpoint. E.g
http://localhost:8983/solr/collection-name/config
and set some property with command like this:
curl http://localhost:8983/solr/collection-name/config
-H 'Content-type:application/json' -d
'{
"set-property": {
"updateHandler.autoCommit.openSearcher": true
}
}'
This could be of course done in Java code, by using some popular HTTP client or by firing your implementation of abstract SolrRequest in SolrJ

Nagios emails not received even when notification is fired poperly

After enabling detailed debugging, I can see that Nagios is firing notifications properly.. Here is what I see in nagios.logs
[1430915423] SERVICE ALERT: test;Check node port;CRITICAL;HARD;4;Connection refused
[1430915423] SERVICE NOTIFICATION: abhishek;test;Check node port;CRITICAL;notify-service-by-email;Connection refused
[1430915423] SERVICE NOTIFICATION: root;test;Check node port;CRITICAL;notify-service-by-email;Connection refused
However, I do not receive emails at the specified contact.. I am using SSMTP..
It is working fine as well.. This command works -
ssmtp abc#xxx.com
Therefore, either 2 things can happen -
notify-service-by-email
is not working OR some security check is filtering out such emails (this should not happen as I am sending emails from my email address).. Can any one suggest how to debug this..?
EDIT - Here is my notify-service-by-email command -
define command{
command_name notify-service-by-email
command_line /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
}
Finally found the issue..
sSMTP was working properly.. Tested it with this command -
ssmtp -s abcd#xxx.com
Enabled DEBUG logs to find out that /etc/ssmtp/ssmtp.conf did not have sufficient permission..
The file was owned by root instead of nagios user
Hope this helps someone..

phantomjs page.evaluate to scrape "resultStats" from http://www.google.com/search?q=site:%s works in local server but not production server

Using phantomjs page.evaluate to extract "resultStats" (div id) from http://www.google.com/search/?q=site:%s works on my local server but not on production server.
NOTE: I'm using the latest phantomjs 1.9.7, however I experienced the same issue with the previous version 1.9.6
NOTE: Phantomjs page.render (on Google home page as well as any other domain name) is working on both servers and creates nice screenshots.
On my production server (Debian stable 7.3 #linode.com) the PHP code below for a top level domain name as the "$url" returns:
TypeError: 'null' is not an object (evaluating 'document.getElementById('resultStats').textContent') phantomjs://webpage.evaluate():2 phantomjs://webpage.evaluate():3 phantomjs://webpage.evaluate():3 null
On my local server (debian testing) the PHP code below for the same "$url" returns:
About 43 results
This happens with any domain name/url I use as the argument - I've tested it on dozens.
What might cause this to occur in my remote production server and not my local server?
gsiteindex.js
var page = require('webpage').create(), site;
var site = phantom.args[0];
page.open("https://www.google.com/search?q=site:" + site, function (status) {
var result = page.evaluate(function () {
return document.getElementById('resultStats').textContent;
});
console.info(result);
phantom.exit();
});
.php
$phantomjs = "phantomjs";
$script = "gsiteindex.js";
$site = $url;
$command = "$phantomjs $script $site";
$googlestring = shell_exec($command);
echo $googlestring;
die();
Well, nrabinowitz was right. I tested it more on my own server using proxies, most timed out, some returned the above error, and a couple returned correct results (well I assume they were correct based on the location the IP address of the proxy - because the figures were a little different than using my ISPs public IP address (calif., USA)).
So it's simply a matter of google blocking certain types of requests from certain IP addresses.
Thanks again for the comment.
Incleude header with user-agent e.g.
header = {'user-asgent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64;
rv:68.0) Gecko/20100101 Firefox/68.0'}
Withuot user agent you get googles gefault style page without resultStats a also had this issue and adding header helped
Default google search page looks like this

Using PhantomJS through Selenium with Python - WebDriverException error

I am using the following code, as recommended here: Is there a way to use PhantomJS in Python?.
from selenium import webdriver
driver = webdriver.PhantomJS()
driver.set_window_size(1024, 768) # optional
driver.get('https://google.com/')
driver.save_screenshot('screen.png') # save a screenshot to disk
sbtn = driver.find_element_by_css_selector('button.gbqfba')
sbtn.click()
When I try to run it I get the following error:
WebDriverException - "Unable to start phantomjs with ghostdriver."
Apparently, this error can be solved by replacing the 3rd line with:
driver = webdriver.PhantomJS(executable_path='/usr/local/lib/node_modules/phantomjs/lib/phantom/bin/phantomjs')
I'm using Windows7, and the path for me appears to be: "C:\Users\myname\AppData\Roaming\npm\node_modules\phantomjs\bin\phantomjs". I have tried using this and variations of it as the executable_path, but I still get the same error. I have also tried adding the folder location to the path. Nothing has worked. I suspect that I am missing something pretty obvious.
Aha!
It was a slightly different location. The line I was looking for was:
driver = webdriver.PhantomJS(executable_path=r'C:\Users\myname\AppData\Roaming\npm\node_modules\phantomjs\lib\phantom\phantomjs')
