Selenium don't initialized if 127.0.0.1 have more then one alias in hosts file #3280

lukeis · 2016-03-03T22:05:09Z

Originally reported on Google Code with ID 3280

What steps will reproduce the problem?
1. write more then one alias for 127.0.0.1, (ex. www.100myr.com) in hosts file in c:\windows\system32\drivers\etc\
2. try to initialize selenium driver (ex. driver = new FirefoxDriver();)

What is the expected output? What do you see instead?
I see next error
org.openqa.selenium.UnsupportedCommandException: Bad request

Command duration or timeout: 1.08 seconds
Build info: version: '2.17.0', revision: '15546', time: '2012-01-16 17:11:34'
System info: os.name: 'Windows XP', os.arch: 'x86', os.version: '5.1', java.version:
'1.7.0'
Driver info: driver.version: FirefoxDriver

Selenium version: 2.17.0
OS: Windows XP
Browser: Firefox 
Browser version: 9.0.1

If I have only one alias for 127.0.0.1 then I haven't error.

I was able to reproduce this error as well on CENTOS 5.  Which by default includes you
machines hostname in /etc/hosts as 127.0.0.1

With my hosts file like:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost vmdev localhost.localdomain
::1             localhost6.localdomain6 localhost6


FirefoxDriver fails.

With my host file changed to:


# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost

127.0.0.2 vmdev localhost.localdomain

::1             localhost6.localdomain6 localhost6

The FirefoxDriver works fine.

This happens both using the driver directly, and through the RemoteDriverServer

I'm seeing exactly the same problem with Selenium 2.20.0 on CentOS 5.7. The workaround
described in the previous comment (Feb 4th 2012) fixed the problem. 

However, I've also noticed that it is possible to run the FirefoxDriver successfully
with more than one alias for 127.0.0.1 in /etc/hosts just so long as the localhost
alias is the first one mentioned. That is, with /etc/hosts looking like below, trying
to initialise the FirefoxDriver fails with the "org.openqa.selenium.UnsupportedCommandException:
Bad request" problem...

------------------------------/etc/hosts---------------------------
# Do not remove the following line, or various programs
# that require network functionality will fail.

127.0.0.1    myalias myotheralias localhost.localdomain localhost

::1          localhost6.localdomain6 localhost6

-------------------------------------------------------------------


But, if the order of the 127.0.0.1 aliases is changed to put localhost at the front
then the FirefoxDriver works fine...

------------------------------/etc/hosts---------------------------
# Do not remove the following line, or various programs
# that require network functionality will fail.

127.0.0.1    localhost localhost.localdomain myalias myotheralias

::1          localhost6.localdomain6 localhost6

-------------------------------------------------------------------

Hope this helps.

I tried this with 2.21 and it is still an issue.  Changing the 127.0.0.1 entry fixes
it.

Reported by mattluce on 2012-05-16 14:05:49

lukeis · 2016-03-03T22:05:15Z

I saw some slightly different behavior.

I only had one 127.0.0.1 entry in my hosts file but the host associated with it was
localhost.mydomain.com.

Under this configuration Firefox would launch when executing my tests through maven
but would fail to launch with the above error when using the TestNG plugin in Eclipse.

I added another entry for 127.0.0.1 just 'localhost' and now Firefox launches in both
maven and eclipse.... weird.

This happens for us as well.

java.version: '1.6.0_33'

My hosts file:

127.0.0.1       localhost.domain.com localhost

If I change it to...

127.0.0.1       localhost localhost.domain.com

...everything works fine.

Our companies servers hosts file is updated from central server every hour and it's
not possible to change that, so the fix is needed.

the localhost, localhost.localdomain entries (so that it's at the end), then it works.

In order to allow connections from aliases other than "localhost" one have to start
FirefoxDriver with a tuned profile:

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference(FirefoxProfile.ALLOWED_HOSTS_PREFERENCE, "alias1,alias2");
WebDriver driver = new FirefoxDriver(profile);

The fix will be released in version 2.43

Problem: this is reproducible when using Selenium Grid. Unfortunately, there's no way
of using ALLOWED_HOSTS_PREFERENCE for RemoteWebDriver. Can we reopen this?

I too have the same problem

The line in my /etc/hosts is as follows

Tried setting it like
profile.setPreference(FirefoxProfile.ALLOWED_HOSTS_PREFERENCE,"localhost.localdomain,loghost,localhost");

But that does not work.
