I always know when I am running behind on a newsletter - someone always
says, "I haven't seen one of your newsletters for a while." So here it
is.

Two new SCO products out this month - read on.

My thanks to those who have been using and commenting on our customer

Coping with the MS authentication change

Remember when you had to change your Windows98 PC registry to "Plain
Text Passwords" so that you could utilise the MS share folders on your
UNIX/Linux server running SCO VisionFS or Samba?
I have seen with the increased upgrading of older PCs to the newer MS XP
and 2000 PCs on sites a little hickup has again arisen. With the mix of new
XP/2000 PCs and the older Windows95/98 PCs, the XP/2000 PCs can't access the
share folders like the older PCs can.

The issue here is you need to change your server's version of Samba or
VisionFS to the latest release to allow the XP/2000 PCs to "see" the SCO
or Linux server. Even sites that have been running with encrypted
passwords for the older Windows95/98 PCs still do not escape this issue
of XP and 2000 not being able to access the server via Microsoft Client
Network browsing.

For those running SCO VisionFS you will need to get the last released version
of 3.1 to grant access to the XP/2000 PCs. As for Samba, it is always
good to get the later version anyway.

Both these products are available as free distributions.


SCO OpenServer 5.0.7

On the 14th of January this year, SCO announced the releasing of its
latest version of SCO OpenServer.

SCO OpenServer 5.0.7 follows the previous releases of its product
"bundles" as Enterprise System, Host System, and the Desktop System.
Included in the media kit are some extras including eval and demo
version of the product. It includes the following new, fully-supported
products: Samba, Mozilla, OpenSSL, OpenSLP, and OpenSSH, OpenLDAP, and many
other commonly used Open Source libraries and tools. Perl and Apache are
now fully integrated into the system, and Apache has been enhanced with
support for PHP, XML, ASP, and other Apache technologies such as mod_perl.
For text-based web browsing, Lynx is now provided with this release. The
Squid caching proxy server, BIND, FTP Daemon, and IP Filter have been
updated.

SCO OpenServer 5.0.7 has new hardware support for USB, EIDE CDRW,
LS-120/240 drive support, updated graphics, updated network adapters and
hard drive adapters. It also has new processor and chip set support.

In line with SCO OpenServer 5.0.6 it follows the same upgrade path and
licence compatibility as existed between a 5.0.5 to 5.0.6 upgrade. (Same
user licences etc).

As SCO OpenServer has remained a primary product focus for DAVROM
CONSULTING along with our other Linux and Internet product offerings,
we have setup a detailed web page on SCO OpenServer 5.0.7:

If you have any questions concerning 5.0.7, its pricing and availability
please contact us.

Tech Tip


Controlling the number of pings - I was asked recently if there is a way
to ping a network device for a specific number of times. This is done
under SCO OpenServer and most Linux platforms with the command:

ping -c 3 192.168.1.3

which results in:

PING 192.168.1.3 (192.168.1.3) from 192.168.1.2 : 56(84) bytes of data.
64 bytes from 192.168.1.3: icmp_seq=1 ttl=64 time=0.768 ms
64 bytes from 192.168.1.3: icmp_seq=2 ttl=64 time=0.726 ms
64 bytes from 192.168.1.3: icmp_seq=3 ttl=64 time=0.717 ms

--- 192.168.1.3 ping statistics ---
3 packets transmitted, 3 received, 0% loss, time 2014ms
rtt min/avg/max/mdev = 0.717/0.737/0.768/0.022 ms

Consider utilising a ping count in a shell script such as:

PINGCOUNT=`ping -c 3 192.168.1.3 | grep icmp | grep -v grep | wc -l`

and then use the value of PINGCOUNT, in this case should be "3", to
determine the action of a script.
