CSWS Interface Selection

CSWS Interface Selection

I am running CSWS V1.3 on an AlphaStation with two ethernet interfaces; one 10 Mb/s and one 100 Mb/s. The 10 Mb/s interface is WE0 in TCP/IP Services for OpenVMS (hereafter refered to as UCX) and the second interface is WE1. An HTTP file download uses the 10 Mb/s interface over the 100 Mb/s interface and the question is why?

Re: CSWS Interface Selection

I don't have experience with multi-homed systems yet; but it is something that I will be doing soon. I think the answer lies in section 5.2.3 of the HP TCP/IP Services for OpenVMS Management. http://h71000.www7.hp.com/doc/732final/6526/6526pro_005.html#failsafe_home

I think you need to configure WE1 to be the HOME interface, and WE0 should not be the home interface.

Re: CSWS Interface Selection

Hi,

you didn't restrict SWS to only responding on the WE1 IP address, or did you?

See http://httpd.apache.org/docs/bind.html for details.

In any case, I *think* SWS will respond on the same interface (IP address) that the request appeared on.

HTH,

Re: CSWS Interface Selection

In Apache you can explicitly name the IP address (and port) it will listen to - in general or, if enabled, by virtual host. Martin's link is the right one.

That also means that when a request is received via that address, it will be answered via that address - and by that, via that interface.
