FAQs

Q. I can’t login with my browser. It always says you are not logged into?

R. To use your browser to manage the WebMux™, it must be set to

accept all cookies. Because the cookie sets expired in 8 hours, you

also need to make sure your hardware clock set correctly using GMT.

The message indicates your system clock off. Please refer to page 45

for how to set the internal clock.

Q. I can’t login with my browser because the server does not respond?

R. Your IP address is not on the allowed host list, or the wrong IP

addresses were entered by accident. Using front push button to clear

that list.

Q If I have multiple servers assigned as STANDBY, how does the

WebMux™ choose which server to use if an ACTIVE server goes

down?

R The WebMux™ checks the standby servers in order and activates

each one until their total weight meets or exceeds the server that is

unavailable

Q. Will a server with weight 0 act as a STANDBY?

R. No. A weight of 0 indicates that the server will not accept any new

connections. The state is considered neither ACTIVE nor STANDBY.

This is to quiet the new connections for the server so that it can be

taken out of service.

Q. Is the Server LAN and the Router or Front LAN required to be on

separate IP subnets?

R. It is required that the server LAN and the router LAN be separate IP

subnets.

Q. What notification services are compatible with the WebMux™?

R. Airtouch and PageMart are the services that are currently supported.

Any SMTP server can be used for sending email notifications.

Q. If I’m running a Unix-based FTP, such as wuftp, how can I get the ftp

server in the farm to resolve the WebMux™ IP addresses?

R. The IP addresses typically will not be able to be resolved since the

servers in the farm are typically using non-routable or private network

addresses. In order for wuftp to resolve the IP addresses and stop

complaining, place the non-routable IP address entries in the /etc/hosts

file on those servers.
