Niagara Release 2.3
Revised: May 22, 2002 Niagara Networking & Connectivity Guide
Chapter 5 Connecting to an ISP
Configuring Captive ISP on the JACE-4/5
5–14
Note The first time you view the ras.properties file, it contains remarks explaining each
setting. The remark lines are preceded by a pound sign (see the example above).
After saving the file, the remarks are stripped out and any future edits of the file will
not contain the remarks.
Step 4
Edit the file using the information in Table 5-1 as a guide. At a minimum, you must
configure the following items:
General Properties
• rasEnable—change false to true
• rasMode—change directDial to captiveISP.
• dialOutOnly—leave this at false to allow dial-in to the JACE upon disconnect.
Otherwise, change this to true.
• remoteAddr—set this as described in the Description column of Table 5-1.
• localAddr—set this as described in the Description column of Table 5-1. If the
parameter is missing, add it in the form
localAddr=<value>.
Modem Configuration Properties
• device—change to COM1 if your modem is attached to that port.
• initString—change if you are using a modem other than those that we have
pre-configured.
Tip The Sportster and Zoom initialization strings and update NVRAM commands
are pretty standard. Consider trying them with your modem to see if they work
for you.
• updateNvRamCmd—change if you are using a modem other than those that we
have pre-configured.
• updateNvRamFlag—change false to true if you have updated the initialization
string.
ISP Configuration Properties
• ispPrimaryNumber—set this as described in the Description column of
Table 5-1.
• ispBackupNumber—set this as described in the Description column of
Table 5-1.
• ispUsername—set this as described in the Description column of Table 5-1.
• ispPassword—set this as described in the Description column of Table 5-1.
• ispRetryCount—set this as described in the Description column of Table 5-1.
• ispRetryDelay—change this as described in the Description column of
Table 5-1. Be sure to set the time associated with this parameter considerably
longer than the time referenced in ispRetryCount.
Step 5
If you want to set up a disconnect schedule, add one or more of the following
parameters in the ISP Configuration section, as described in the Description column
of Table 5-1:
