FAQs
I can’t login with my browser. It always says you are not logged in.
To use your browser to manage the WebMux, it must be set to accept all cookies. Because the
cookie is set to expire in 8 hours, you also need to make sure your system clock set correctly
using GMT. The message is an indication that your system clock is off. Please refer to page
84 on how to set the system clock of the WebMux.
I can’t login with my browser because the WebMux does not respond.
Your IP address is not on the allowed host list, or the wrong IP addresses were entered by
accident. Use the LCD panel setup to clear that list.
If I have multiple servers assigned as STANDBY, how does the WebMux choose
which server to use if an ACTIVE server goes down?
The WebMux checks the standby servers in order and activates each one until their total
weight meets or exceeds the server that is unavailable
Will a server with weight 0 act as a STANDBY?
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.
Is the Server LAN and the Router or Front LAN required to be on separate IP
subnets?
It is required that the server LAN and the router LAN be separate IP subnets.
What notification services are compatible with the WebMux?
Airtouch and PageMart are the services that are currently supported. Any SMTP server
configured to allow relaying from the WebMux can be used for sending email notifications.
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?
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.
