BIGIP VE 10.1.0.3341.1084 issue application octet/stream

Hello,

 

i am having an issue while opening virtual server webpage on windows O/S in every web browser.

 

I have defined pool , pool member which is listening on port 81 and virtual server which is listening on port 80. I gave only 1 pool member. Virtual server points to a pool member on which apache is running with coldfusion server.

 

When i connect to pool member directly i can access the webpage ( under windows and linux ).

 

I have set snat : automap . i got 2 client pc virtual machines that are connecting to virtual server.

 

When accessing the virtual server from a linux OS using firefox webpage is generating without any issues.

 

When accessing the virtual server from a windows OS using firefox/chrome/opera/IE , webpage is empty (in IE/opera/chrome), and when i try to open it in firefox it asks me what do i want to do with the Application octet/stream . When i choose save to disk, and open the file, there is no html code.

 

What i really do not understand is that i managed to get it working with 1 trick... On the F5 ltm VE console, i issue command : tcpdump on internal interface , and from windows OS the webpage is accessible. I really do not have any clue why it is starting to work after i run tcpdump from big-ip VE virtual machine.

 

In apache logs while browsing using linux i got normal queries and answers. When browsing with windows in apache logs i see this:

 

* . * . * . * - - [date] "" 501 293 ""-"" "-"" .

 

i really do not know how to connect things like "it works when tcpdump is working" with the issue. Did anyone have any issue similar to mine ?

 

 

Regards,

 

Greg

Hi Greg,

 

 

Can you use Wireshark or tcpdump on the VM host (not on LTM VE) and compare the working scenario from a Linux client with the failing request/response from a Windows client? Check to see if there is anything different in the response headers or content and then the request headers or content.

I made screenshots from wireshark on windows

 

1) while tcpdump -i internal is working

2) while tcpdump -i internat was not running

And a screenshot from linux without having tcpdump turned on on big ip
