WHAT'S NEW ON PUB II 
Guard your ports! 
by Chris Taylor 

Recent issues of the Ottawa PC News have included reviews of 
software designed to protect your computer from the bad guys 
on the Internet. I have written about how, if someone wants 
to connect to your machine (for any purpose, good or bad), 
your computer must be running some software that opens a 
port. 

The trouble is, it is not easy to tell if you have open 
ports on your machine. There are some nasty trojan programs 
out there, such as Back Oriface, that will open a particular 
port. There are people on the Internet scanning for that 
open port. If they discover you are running Back Oriface, 
they can gain complete control of your machine. 

The absence of a trojan does not mean you have no open 
ports. For example, if you enable file and print sharing on 
your computer, you may be offering full access to your files 
to everyone on the Internet whenever you are on-line. This 
is because enabling file and print sharing opens port 139. 
There are programs that will search for computers with an 
open port 139 and enumerate the shares on those machines. 
Then, with a simple NET USE command, someone could map a 
drive letter to your open shares and access your files. 

I wrote about a couple of Internet Web sites that will run 
port scans on your computer, looking for open ports. 
Probably the most famous of these is the Shields Up site run 
by Steve Gibson at http://www.grc.com. Unfortunately, 
Gibson's site only scans for a few of the most common ports. 

However, there is software available that you can run on 
your own computer to check for open ports. If you are not 
running any sort of firewall, you can use this type of 
software against your own machine and get a pretty good 
picture of what a hacker might see if they were to run a 
port scan on you. If you are running a firewall, you might 
get a friend to run a port scan on your machine while you 
are both connected to the Internet. 

Now to finally get around to the title of this article! 
SuperScan v2.06 is a free port scanner you can download from 
PUB II's file area 35 - Internet, as sscan206.zip. There is 
no installation routine. Simply unzip the files into a 
directory and run scanner.exe. 

There are lots of options, but to do a simple scan looking 
for any open port on your machine, you can just enter 
localhost in the "Hostname Lookup" box and click the 
"Lookup" button. Then, in the "Scan Type" section, select 
the last option, "All ports from" and enter 1 to 65535 in 
the boxes next to it. Then click the "Start" button. The 
results box will show any open ports. You can click the 
"Expand all" button to see additional details. 

If you are behind a firewall or want to be certain about 
what is seen from the hackers' perspective, you can team up 
with a friend and port scan each other's machines. All you 
have to do is have both machines connect to the Internet. 
Then determine what your IP address is by running 
winipcfg.exe (on Win9x machines) or ipconfig (from a cmd 
prompt under WinNT). You can e-mail your IP addresses to 
each other so you can stay on-line and maintain the same 
address. Finally, each of you can fire up SuperScan and 
enter the other person's IP address in the "Hostname Lookup" 
box and follow all the other instructions above. 

So, what do you do if you find open ports? The first thing 
to do is find out what is opening the port. A good resource 
for common port usage is RFC 1700. You can download it from 
PUB II in file area 35 - Internet as rfc1700.zip. Many 
applications use non-standard ports, but at least it is a 
good starting point. 

If you have file and print sharing enabled, you should find 
that port 139 is open. Visit Gibson's site at 
http://www.grc.com/su-bondage.htm. for a good explanation of 
how to close this open port. Gibson has some other good 
information available on other pages as well, so browse 
around. 

Some of the other ports you might find open may be harder to 
close. There is no magic bullet to eliminate the problem. 
You can try a clean boot and see if the port is closed. You 
can open programs one at a time and see if you can identify 
the one opening a port. You can run a good virus scanner 
that might pick up on a trojan program that is doing it. 

You may find that the best solution is simply to install a 
personal firewall that will block anyone who attempts to 
connect to your machine. Many of the available firewalls 
will also block outbound traffic unless you specifically 
allow it. Since Trojan programs can attempt to do nasty 
things like send password information to some hacker on the 
Internet, this can be of great help. 

Some programs are free for personal use, such as ZoneAlarm, 
Sybergen Secure Desktop, and PortICE. All are available on 
PUB II in file area 35 - Internet (zonalm21.exe, 
ssd21464.zip, and portice2.zip). 

There are also a number of commercial products, such as 
Symantec's Norton Internet Security, ZoneLab's ZoneAlarm 
Pro, Tiny Software's Tiny Personal Firewall, Network 
Associates' McAfee.com Personal Firewall, and Network Ice's 
BlackICE Defender. 

Once you install a personal firewall, you can use a port 
scanner to verify it is doing its job properly. To do this, 
you will have to have help from someone outside of your 
firewall to run the port scan. Running it on your own 
machine will not tell you what you need to know. 

A word of caution on using a port scanner: NEVER use a port 
scanner on anyone but yourself or someone who has asked you 
to do so. Running a port scan is generally considered to be 
an attack. If the person on the other end detects a scan, 
they may report you to your Internet Service Provider. Such 
a complaint could get your account with your ISP terminated.

Club meeting dates may change 
by Chris Taylor 

As you will have noticed, the meeting this month is on the 
second Wednesday of the month, as it was last month. While, 
as of this writing, we have not yet received confirmation 
for all our meeting dates this year, a bit of explanation is 
in order. 

Last year, a number of members expressed interest in also 
attending the Ottawa Carleton Linux Users Group meetings. 
They happened to meet on the first Wednesday of the month. 
Since each summer we have to go to the museum and book our 
meeting dates for the rest of the year, the Board of 
Directors decided to try for a different night that would 
allow members to attend both Groups' meetings. We decided to 
try to maintain a Wednesday night for the meeting in the 
hopes that a change to a different Wednesday of the month 
would result in the least number of conflicts members might 
have in their schedules. 

As soon as we have received confirmation of all meeting 
dates for the rest of the year, we will let you know.

COMPUTER HISTORY 
Colossal code of silence broken 

Submitted by OPCUG member Paul Cooper from the "Electronic 
Telegraph", the Internet version of the London Daily 
Telegraph. Story by Roger Highfield. 

After 55 years the boffins who shortened the war against 
Hitler can reveal more of their secrets. THE most important 
computer upgrade in history, one that enabled the Allies to 
"read the mind of Adolf Hitler" before D-Day, is about to be 
revealed in detail after half a century of secrecy. 

This month, the Government Communications Headquarters at 
Cheltenham (GCHQ) will release to the Public Record Office, 
Kew, a 500-page technical report on Colossus, the forerunner 
of the post-war digital computer and the first practical 
application of large-scale, program-controlled computing. 

Many are familiar with Colossus but the report also contains 
the specifications for "Colossus II", an upgraded machine 
which began operation on June 1, 1944. "The modification was 
very important," said Dr. David Rees, emeritus professor of 
mathematics at Exeter University, one of the code-breakers. 

Colossus II started work in time to decipher high-level 
messages which confirmed that Hitler had swallowed the 
Allies' deception campaigns over where the invasion force 
was to be landed, giving the Allies the confidence to go 
ahead with the invasion of Europe. By the end of the war 
there were 10 Colossi at Bletchley Park, the secret 
establishment in Buckinghamshire that broke German, Japanese 
and Italian military codes  -  which some experts believe 
shortened the Second World War by two years. 

"Some will be startled to know that by VE Day Britain had a 
machine room of some 10 high-speed electronic computers on 
three-shift operation round the clock," said Dr. Donald 
Michie, 76, a former Bletchley cryptographer who is emeritus 
professor of machine intelligence at the University of 
Edinburgh. 

A standard history of computing will probably say that the 
first electronic digital computer was America's ENIAC, which 
went into operation in 1946. But the modified Colossus "had 
a functionality equal to the much later ENIAC, and zillions 
more data-processing throughput", said Prof. Michie, who co- 
edited and co-authored the report with the mathematician Dr. 
Jack Good following the German surrender in 1945. The report 
details the specifications and conceptual blueprint of 
Colossus. More important, it describes the upgraded version, 
Colossus II, which could (unlike Colossus I) be programmed 
to a limited extent, marking a key advance in computing of 
the day, before fully programmable machines were built a few 
years later in Britain and America. 

"The modification gave Colossus an extra bit of brain, so to 
speak, to extend its repertoire," said Prof. Michie. "There 
was a crash programme to build it, and more like it." 

There were two, quite different, German machine cipher 
systems: Enigma, for tactical purposes, such as the U boat 
campaign; and Lorenz, for high-level strategic traffic. It 
is well known that the Colossus carried out the major step 
in the decryption of the Lorenz radio traffic, referring to 
the device developed by the electronics company Lorenz to 
scramble messages that streamed between Berlin supreme 
command and some 10 army group HQs. 

The Lorenz Schlussel-zusatz 40, or Tunny as the British 
called it, resembled a mechanical cash register and 
converted a typed message into code using two sets of five 
"coding" wheels, among other confounding features, including 
two "motor" wheels. Even though one was not captured until 
German capitula- tion, the Bletchley cryptanalysts were able 
use the settings found by Colossus to set up a "virtual" 
Tunny: Bletchley's very own Tunny was deduced by Bill Tutte, 
a young mathematician, after a mistake made by a German 
radio operator on August 30, 1941. The operator sent a 4000- 
character message, after which the receiving station replied 
"didn't get that, please resend". The operator obliged, but 
with the same start settings, which was forbidden because 
the machine then generated the same stream of obscuring 
characters. 

Crucially, these two streams of obscuring characters (or 
"key"), being exactly the same, cancelled each other out 
when the two intercepted transmissions were superimposed. 
But the operator had not fed the plain-text message into the 
enciphering machine at exactly the same point on the two 
occasions, displacing them by a 'stagger' of a couple of 
characters. The result of the superimposition was a message 
in military German added to itself at a small stagger. 

From this error, the code-breaker Brigadier John Tiltman was 
able to reconstruct the original message and deduce the key. 
After four months' toil, Tutte could infer the entire Tunny 
design, a remarkable achievement. But the Germans changed 
the patterns of ones and zeroes around the circumference of 
the Lorenz machine's 10 coding wheels, initially monthly, 
and eventually daily. At first it took the code-breakers 
days to find the correct combination of start settings to 
decode a message using known patterns, but months to find a 
given set of new patterns. 

The mathematician Max Newman conceived a way to automate the 
effort to crack Lorenz codes, one reason why the document on 
the Colossus, The Tunny Report, is often dubbed "The History 
of the Newmanry". The result  -  the room-sized Colossus I 
-  was born in 1943, the descendant of a prototype called 
"Heath Robinson". Containing 1500 valves, 10 times more than 
electronic machines of the day, Colossus I was built at the 
Post Office Research Station at Dollis Hill by Dr. Tommy 
Flowers and colleagues. 

The new report fills a gap in the Colossus story: the 
addition of a new trick for semi-automatically breaking the 
Lorenz patterns, "wheel breaking", which emerged from a 
technical proposal by Prof. Michie, then just 20 years old. 
Because the modification boosted code-breaking by between 10 
and 100-fold, it unleashed an all-out effort to crank out 
Colossus II. No one has described in print the crash 
programme to get at least one operational before D-day and 
as many as possible installed as soon after. 

"The devil lay in the detailed implementation of the new 
design," said Prof. Michie. "One of the design engineers in 
charge of the key hardware modification is still alive, and 
now at last also free to talk. His name is Harry Fensom." 

Fensom, 79, was one of the "lads", the engineers who worked 
on Colossus and the complicated circuits to conduct the 
wheel breaking modification, coyly referred to it as the 
"special attachment." Work on Colossus II, which contained 
2,500 valves, began in January 1944. "For Colossus II, we 
had the resources of the country at our disposal," said 
Fensom. "We were top priority. We could demand anything and 
we got it." The machine went into operation on June 1, just 
in time to decipher messages confirming that Hitler had 
swallowed the deception campaigns, the phantom army in the 
south of England, and the phantom convoys. This gave 
Eisenhower and Montgomery the confidence to go ahead with D- 
Day.

1999 annual report figures re-visited 

by James Fridrich, Treasurer 

There is a correction for the 1999 figures published earlier 
this year. Here are the amended figures for the 1999 Annual 
Report.  The original report published in the OPCUG 
newsletter early in 2000 shows a discrepancy of over two 
thousand dollars. This is a significant amount, and a 
correction is in order. The problem lies in the accounting 
and reporting procedure, not in the actual funds. Our bank 
records are (and have always been) balanced with our Quicken 
bank records. 

The OPCUG treasurers use an accounting register called 
Quicken99. The reason for the discrepancy is that I posted a 
transaction to the incorrect account in Quicken, which 
balanced the bank account, but not the allocation of funds. 
There are 37 accounts set up by past treasurers in Quicken, 
some of which are a mystery to me (mainly boiler accounts 
generated automatically and not used), and all must be 
maintained. The discrepancy was found when a transfer of 
funds went from the Scotiabank account to our current Royal 
Bank account. When Quicken generated the report this 
transaction didn't get included. There was never a 
discrepancy in the paper bank records, only in the generated 
report. 

I apologize for the error, in the 1999 report. My intention 
was to correct this error after the completion of a review 
to verify the OPCUG cash flow. This review has been 
completed and has been accepted by the board of directors. 
The review was for the past three years; a fair amount of 
work of which I didn't have the time to take on. Many thanks 
to Morris Turpin and John Archibald for graciously 
volunteering their efforts conducting, and completing the 
review. 

Although I am familiar with accounting and bookkeeping 
principles; area of expertise lies more in manual accounting 
procedures than financial analysis. I was unfamiliar with 
Quicken99 when I first took over the treasurer position in 
November 1999. Since 1999 I have become much more familiar 
with Quicken99 and have located where the problem was, and 
fixed the report which now agrees with the accepted figures. 
The report is as follows:
