Today's topics:
- Temporary disk space for large files.
- IP link to abroad.
- RLOGIN and TELNET to the VAX.
- Running X-window applications from the VAX to your station.
- JANET addresses revisited...
- BITNET nodes list.
o A large temporary disk space has been defined for short time usage.
It is pointed by the logical name TEMP$; note that files will be
deleted from there when there is lack of space. This temporary space
is given as long as we can do it. When disk space becomes scarce this
area will be taken for other usage. Users are requested to delete
unneeded files from it, in order to let other users use it.
IMPORTANT: this disk space is not backed up.
o IP link to abroad: The IP link to NyserNet has finally been
connected. It is possible now to FTP and TELNET to almost everywhere;
all you need is the full name of the host at the other side. Since
the line is slow, the translation of name to address might be long (up
to a minute). Please also refrain from doing un-needed FTP sessions,
as this degrades the interactive performance quite badly.
A faster line is anticipated to be operational in a few months,
but that's only what Bezeq promise... (the current slow line should
have been installed months ago, according to Bezeq's promises).
This international line will be accessed only via the mainframes
and department's central machines; there will be no direct access from
terminal servers or PC's. This is done in order to prevent
unauthorized access to this line from users not belonging to the
Hebrew University.
As long as we have a slow line to the InterNet, mail traffic will
not be routed on it, but we'll continue to use the old BITnet link for
it. When the faster line will be installed we'll reconsider this
policy.
o RLOGIN and TELNET to the VAX: RLOGIN does not display the login
message to users. Hence, if you login via RLOGIN you loose messages
about system shutdown, etc. If you use TELNET from your workstation
and leave the session open for a long time, we suggest that you'll
logout and login again once a day or two to review the new
announcements.
o X-windows: It is possible to open an X session from the VAX to your
station; it can be done to any workstation which supports the X
windows protocol. The way to do it is described here shortly. A more
detailed manual is available at the VMS group in Taylor building.
In order to create an interactive session, TELNET to the VAX, and hit
the command:
$ WINDOW node-name
Where node-name is the name of your station. After the window has
been created you can logout from the TELNET session. Now you have a
VT-320 terminal window. Most of the standard applications will run as
normal, except from the debugger which will create separate windows
when run from this window.
There is a utility called FileView which allows you to walk through
your directory tree, edit and compile files, and more using the mouse.
In order to start it issue the command (applicable only when you are
logged in via a window as described above):
$ FILEVIEW
which will open a new window of the FileView sessions.
More commands are available (like MAIL inside windows, etc) which take
advantage of the windowing system. For a more detailed explanation,
look in the above mentioned guide.
o JANET addresses: This issue comes back each time, and will probably
continue to be a problem... JANET (the British Academic Email
network) writes the addresses in the reverse order we are used for.
However, when mail is sent to there from outside, the reverse order
should be used (i.e the "right" order we are used for). To make it
more clear, inside Janet an address will look like: USER@UK.AC.B.A;
when we send mail to this address from here it MUST look like:
USER@A.B.AC.UK; thus, if you see an address which has UK.AC
immediately after the at-sign, reverse the order of the address
components.
o BITnet nodes list: A list of all BITnet nodes is placed in the file
UTIL$:BITNET.TXT; this list includes a short description of each node,
so you can search in it. This is list is updated once a month.
InterNet addresses are harder to find out. If you need an address
there, please send Email to the VMS group people.
