Re 222: In fact, there's a joke in there somewhere.
"I was at the computer store, and the sales guy was supposed to give me $7.12
in change. He was out of dimes, but instead of 2 nickels I grudgingly
accepted an NE2000 clone."

<chuckle> True. I do think it's ironic that we're still using PCI
clones of one of the worst ethernet card designs ever. On the other
hand, CPUs are so fast now that hardware efficiency hardly matters for
such things. I use 'em and they work great. :>

I found the MacTCPWatcher website and downloaded the utility. However the
Trace option was grayed out and the documentation declares " Note that
Traceroute is an OT only function. You cannot use it under MacTCP. (The
button greys out under MacTCP.)" I guess it should be called
MacOpenTransportWatcher.) Anyway, PING works, but returns no responses
from cyberspace.org.

Shoot. We need traceroute, to find out where the packets are dropping.

Can we run it in the other direction? Trace from Grex to Rane's
machine, provided he can identify its IP?

Last I heard, only staff could run traceroute. If we know when he is online,
and the IP address, we can give it a try.

Re: #226: We're still using clones and kludged upgrades of one of the
worst-designed CPUs ever, too. There are rumours that IBM was going to
go for the MC68000 for the original PC design, but rejected it on the
grounds that it was too expensive and there weren't many expansion
cards available for it... If only...!

Yellow Alert:
In the next few weeks, UM ITD and CAEN will stop allowing telnet and FTP to
and from there. Sometimes I try to telent over to grex from school. The few
times I've tried SSH, I get cut off because Grex is using some funny version.
Until now I didn't care; telnet and FTP worked. Soon they won't and I wont
be able to get to Grex during the day.
Can someone help me figure outhow to check email and move files when telent
and FTP are forbidden?

Hmm. My machine's version of SSH is too new to be compatible with
Grex, so I told it to use rlogin (whatever that is) and I've had no
difficulty establishing or maintaining a connection using the SSH
utility since.
I'm not sure if that translates, but perhaps someone with more
knowledge than I about these things can use it to help you.

Re #232: Grex is running an old version of SSH. What client are you
trying to use to connect? If you have the option, make sure you tell it
to use SSH protocol version 1 instead of version 2.
rlogin is non-encrypted, so it's not as good as SSH but it's no worse
than telnet.
If you get SSH working you can use SCP to copy files to and from Grex,
assuming you can find a client. (Under UNIX-ish operating systems the
'scp' command should work.)
I don't know of a good SCP client for Windows that works on Grex.
Normally I use WinSCP, but it doesn't seem to work with Grex...I get
this error:
Error listing directory "/a/g/u/gull".
Unexpected directory listing line "drwxr-xr-x 5 gull 2560 Dec
8 18:00 .".
Operation aborted
Maybe Grex should upgrade to a newer version of SSH.

I've just logged in to grex from ITCS' login servers (login.itd.umich.edu),
using the version of ssh installed there. Because my login id on both
systems is the same (but the passwords aren't), I created a new id to
test with; that one also worked from login.itd
I did get the warning about the server lying about its key size, but it
still worked.
If you are not using login.itd, you may need to talk to the administrators
of the system you are using.

I too get the warning about the server lying about its key but it's not
always . ..sometimes I get it and sometimes I don't.

re #232: if "ssh grex.org" doesn't work because the host you're trying
from wants to talk a newer version of the ssh protocol, you might try
"ssh1 grex.org". Some machines support an "ssh1" command for backwards
compatibility.

For windows, try putty and psftp to connect to grex.
To find them, try this

Right, putty works great, and it has a pscp client (though you download that
separately).
Colleen - I happen to be in the UM library at the moment, and I couldn't ssh
directly to Grex either (using SSH Secure Shell, version 3.2.3). It says
it's downgrading to version 1 to connect to Grex, but then it craps out
anyway.
However, I am able to use Secure Shell to connect to login.itd.umich.edu,
and then from there type "ssh -l aruba cyberspace.org", which connects me to
Grex just fine. Kinda clunky, bt it does work.

I've never been able to get putty to work with Grex. Might be a configuration
issue.

Re #s 227-230: I will probably be on too irregularly from Florida - and only
until tomorrow....so we'll probably not be able to trace this problem....
oh well, I have been able to get on these past few days.

I used to use putty with Grex all the time. Worked fine, I used ssh from an
NT 4.0 box.

Re #243: I assume you can get other ssh clients to connect to Grex in
the same environment? I use PuTTY to connect to Grex also. Configuration
could be the problem. I had to fiddle with the "ssh" settings a bit.

I can confirm that PuTY does indeed work with Windows, (XP in my case)
