Problems using farutil

In order to be able to configure Frame Relay you must use the version of farutil supplied with this release. Invoke the farutil command and ensure that its output is as follows.

[root@minion root]# farutil
usage: farutil [-v] interface command [parameters...]

Commands:
        card                       #Display card type and number of ports
        info                       #Display status info for port
        load firmware1 firmware2   #Download firmware and start card
        create dlci                #Add PVC to master device
        delete dlci                #Remove PVC from device
        set options...             #Set configurable options

[root@minion root]#

If your version is still the old version then you need to make the new version and copy it to the /sbin directory as follows:

[root@minion common]# cd /x21/farsync-0.09.4/common/
[root@minion common]# make farhdlc
cc -o farhdlc -DGEN_HDLC=1 -Wall -Wstrict-prototypes -I../kernel2.4 -g -I/usr/src/linux/include farutil.c
[root@minion common]# cp farhdlc /sbin/farutil
cp: overwrite `/sbin/farutil'? y
[root@minion common]#
