- This doesn't really count, but in August, I was vacationing at my cabin
- on Saltspring Island, B.C., Canada. We have electricity and a phone... no hot
- water or anything like that... Anyway, I was sitting on the porch, under a grape
- vine, looking out over our lake, in the pleasant hot sun... on internet.
- It was actually no biggy.... my dad has DATAPAC access so it was
- only a matter of a long distance call to the nearest DATAPAC node [on my dads
- laptop], then a telnet from my dads account to my own... but the condradiction
- was quite humorous... a computer geek in the sun, still being a computer geek.

- ObHack: This isn't really a hack, but I was impressed with myself by getting as
- far as I did.
- At school, we have two [big] networks. The Engineering faculty has a
- IBM PC network, and the math/computer science faculty has a UNIX system up.
- There are modem lines on the UNIX net, but the 7bit lines are always full, and
- the 8 bit lines (and high speed lines) cost money. Being a poor and struggling
- student, I didn't want to have to pay to dial in (and being a lazy student,
- I didn't want to spend the 10 minutes to walk over to school). Now the PC network
- is pretty flimsy, but they have two free modem lines. Having spent a year in
- Engineering, I knew my way around the PC network fairly well, but it didn't have
- a reliable FTP and the telnet was limitted to only other on campus nets
- (ie: the unix net).
- Due to some small (and completely legal) hack at registration time, I
- managed to get myself an account on the Engineering net. So usually I could dial
- into that network, telnet over to the UNIX net, and then I was free to email
- and USENET to my hearts delight.
- Well, one day, during exams, at about 2:00am, It was absolutely imperitive
- that I read my mail account before 8:00am, and I don't like to get up before
- noon unless it's for money, or absolutely neccessary. So i dialed into the
- engineering network, and tryed to log onto my account there... unfortunately,
- the server I was on was down. Really not wanting to walk over to school at this
- time of night (I just wanted to go to bed), I set my mind on getting into
- the network however I could.
- The network had some 'scratch' accounts that you could use, but all it
- was was this little menu program that enabled you to do 'whois', 'kickoff'
- and a couple of other things. (No DOS prompt, and no telnet). Well, it was
- easy enough to do a couple of 'ctrl-c''s to get myself to a dos prompt. Then
- I tryed to telnet to the appropriate UNIX server, and I got the message
- "You are not authorized to use TELNET". Not being detered the least, I
- decided to find the right programs and make them skip over the bit that told me
- I wasn't allowed to telnet. On PC networks, almost every thing is done through
- batch files, and it's trivial to modify batch files.. so I ended up
- copying the appropriate batch files to my tempdir, modifying the appropriate lines
- and tadah... telnet access... or so I thought... when I tried to telnet
- across, the server just wouldn't connect... not being absolutely sure that
- I completely hacked the telnet batch files (three levels deep), I decide to
- call a friend of mine who had an account on a different server, on the PC net.
- So I got his password, and logged in, telneted and the same thing happened
- (No connection).
- So it turned out that my little 'crack' worked, but it wasn't my fault
- I couldn't get through (the UNIX side server was down) and I had to walk over
- to school =-(
- No, I don't think my actions were bad, because I did have
- authorization to telnet, but the server my account was on was down, so I feel
- I was justified.
- As an aside, I tried the same thing this term (I had to long distance call
- down to school), and they must have found out about the hole in security,
- because the tempdir that you get for a scratch account is now read only, and it
- doesn't run the standard login dos batchs (set path, prompt, and access dos disk).
- This was easy to fix, just get a tempdisk, do a subst with your tempdir (the N:
- you get at login) and then access the DOS disk, and setup the path appropriately.
- It wasn't any harder, just took longer.
