Re: [jetty-users] UPDATE: calling setHost under jetty v9.4.8.v20171121 c

[west suhanic <west.suhanic@xxxxxxxxx>]

Hi Greg:

I said yesterday that I had a fix. Well after more testing my fix of using an IP address

with the setHost call did not solve the problem. It led to more problems. The problems

were only resolved when I either do not call setHost or call it with a null parameter; i.e., setHost( null ).

My code base has been running smoothly with setHost( hostName ) where hostname is the fully qualified domain name

for several years against  Jetty v9.2.1.x and most recently Jetty v9.4.1.v20170120. The problems arose when I

upgraded to Jetty v9.4.7.v20170914 and Jetty 9.4.8.v20171121 .

I am using jetty with jdk-8u152 running under gentoo on an X86-64 PC.

My network setup is fine with the machine being accessible to all machines on my internal network.

I am OK with using setHost(null) but I was wondering if you have any suggestions?

thank you,

west suhanic

West,

Sounds like there could be some DNS resolution problems on your machine.

Can you do a host lookup for "aaa,bbb.ccc" and get 192.168.20.9? from the command line?

Perhaps try writing a little test main in java to check that InetAddress can also look up the name and resolve it.

regards

Hello:

This is an update to my previous email.

If I use an actual IP address in the setHost call everything works as expected.

For example:

 ServerConnector http = new ServerConnector(server,
                new HttpConnectionFactory(http_config));
 http.setPort(8080);
 http.setHost( "192.168.20.9" );
 http.setIdleTimeout(30000);

works as expected when contacted using the following URL:

http://aaa.bbb.ccc:8080/index.html

thank you,

west suhanic
