A45: First thing is to make sure you are using the right command to
read the tape. (For example a tape created with ufsdump cannot be
read by tar.) So check with whomever wrote that tape.
Second thing is to make sure you are using the right drive. (For example, a
125-m DAT tape cannot be read by a DDS-2 DAT drive.) So check the
tape drives web page.
Third thing is to determine whether it is a drive or a tape problem. Try the
tape you are having problems with in another drive (that can read your
tape--see previous paragraph). If it works there, then use it there and report
the other drive was bad (assuming it was not known to be experiencing some
outage). If it doesn't work in
that another drive, try writing to a blank tape in the drive that couldn't
read your tape in the first place. If the new tape can't be read (back), then
there is a problem with the drive--please report it--but chances are that your
tape is bad as well. If the new tape can be read successfully, then your tape
is definitely bad.
There are two main reasons why your tape could be bad. Either it got
``corrupted'' when the first record was overwritten by mistake, or it has
physically deteriorated. In either case, data recovery will be very difficult
(if at all possible)...
Q46: How can I access web sites restricted to computers in the
UCLA domain from home?
A46: Use our web server (www.astro.ucla.edu) as proxy. Access to
the proxy service is restricted, so you must
e-mail your IP address and
request it before you can use it. It is available to static IP
addresses only (i.e. mostly cable modem/DSL/fixed wireless customers).
You should use the proxy only when necessary; otherwise all your browsing will
be slowed down since it will first go through our web server. Also, keep in
mind that anyone with an account in our domain can look at the web server log
files and find out what web pages you were looking at and when, whenever you
use the proxy service...
Alternatively, if you have a Bruin OnLine account, you can use the
regardless of whether you have a static IP address or what ISP you use.
Q47: What news/NNTP/USENET server is available?
SunOS, the environment variable NNTPSERVER is automatically set to
that for you.
Q48: How can I get the drivers for our printers (to install on my PC)?
A48: You don't need to worry about this anymore. Just follow the printer installation instructions and you should be good to go.
