ntpdate problem in Unixware
Hi Guys,
A weird problem. I have disabled ntpd daemon on a HP server and placed
ntpdate in crontab instead and redirected the log to a file. This command
in cron synchronizes the server with a local time server every 15 minutes.
The weird part is that on 3 specific times (5:00 am, 10:00 am, 15:00 am)
the offset is BIG. 15 seconds for example. Take a look at this log:

19 Jan 14:15:00 ntpdate[25822]: adjust time server 132.147.1.83 offset -0.035859 sec

I am really confused. Why
this happens every 5 hours exactly on those times?? Any idea?
I appreciate your help.

ipx_cmd

IPX_CMD(8)						      System Manager's Manual							IPX_CMD(8)

NAME

       ipx_cmd - bridge between Novell's SCMD driver and local IPX network

SYNOPSIS

       ipx_cmd -A server name [ -l local interface name ]

DESCRIPTION

       ipx_cmd moves packets from tapN to server and vice versa.  It is something like IPX Tunnel, but it uses Novell Netware 5 server Compatibil-
       ity Mode Driver (AKA Migration Agent) on the other end of wire. You must first configure your kernel tapN device with IPX EthernetII  frame
       and with network number set up on server (you can use kernel autodetection).

OPTIONS

       -A server name
	      This is IP name of compatibility mode server. You can use DNS name or dotted quad to specify server address.

       -l local interface name
	      This allows you to specify, which of your IP addresses should be used as IP address of client side of CMD driver. You must configure
	      your tapN device with hardware address 7E:01:AA:BB:CC:DD, where AA:BB:CC:DD is your IP address in hexa.

EXAMPLE

       If you are on server platan.vc.cvut.cz (147.32.240.81) and your migration agent runs on server boris.vc.cvut.cz,  you  can  configure  your
       system with:

	  insmod ethertap
	  ifconfig tap0 hw ether 7E:01:93:20:F0:51 up
	  ipx_interface add -p tap0 EtherII
	  ipx_cmd -A boris.vc.cvut.cz -l 147.32.240.81 &

BUGS

       This program was written to satisfy my own needs and should be really improved.	At least it should configure tap interface itself.
