CN2510 User’s Manual Troubleshooting
A-6
SLIP/PPP Connection Problems
Problem: Cannot make a SLIP connection to a remote host.
Solutions:
¾ Check to see if the CN2510’s SLIP port baud rate (in the Port Æ Line menu) is the same
as the remote host’s baud rate.
¾ Check to see if data bits = 8.
¾ Check to see if the XON/XOFF flow control is the same as the remote site.
¾ Check to see if the RS-232 cable is wired correctly. If the port is utilizing RTS/CTS
hardware flow control, then the RTS, CTS pins should be included. In this case, cables
with only pins 2, 3, and 7 will not work.
¾ Make sure there is no “getty” or other process using the SLIP port on the remote site.
RADIUS Problems
Question: What can I do if there is an authentication check failure on the radius server?
Solutions:
¾ Check to see if the console password is the same as the radius server’s radius key.
¾ Make sure the password was entered correctly.
¾ Make sure the account and password in the login script are correct.
¾ If the authentication check runs for a long time and then times out, check to see if the
RADIUS Server’s IP is correct. E.g., set up one port as Rtelnet, telnet CN2510’s TCP port
from radius, and then telnet CN2510’s console and check the Monitor {line} status. Check
to see if the remote IP address matches the radius IP address you set in the CN2510.
Question: Why can’t I compile radius software on a system running Linux Red hat 5.0?
Solutions:
Take the following steps if you compiled RADIUS2.3 on Red hat 5.0 or above:
1. Save makefile-SCO as a file named makefile-LINUX, and then modify the content as
follows:
#
# make file for LINUX
#
LIBS = -lcrypt
include Makefile
2. Add two similar line to the shell program “mk_radius” at read_os “1”. For example, they
might appear as follows:
read_os
case $ans in
‘1’)
clear
mk_src
echo “enter lib directory”
cd lib
echo “compiling source program ....”
make
cd ..
echo “linking program .....”
make -f Makefile-LINUX;;
