Are there any prospects for user partition backups any time soon?

I think Grex's policy has always been that the user partition is not
backed up on any regular basis. As long as I've been here there have
been warnings not to store anything too important there.
It doesn't take too long to tar up all your files and then use FTP or
SCP to copy them to your home machine.

I'd like some help in doing that. I can do it file by file, but can I just
compress and download my whole directory, and open it as needed on my
home Mac (OS X)? If so, how (e-mail me, if it convenient).

I'll post it here, so that other people can benefit, too.
To get all your files into one tarball:
Change to your home directory and type
tar cvf mystuff.tar .
If you then want to compress it, type
gzip mystuff.tar
and you'll end up with a file called mystuff.tar.gz.
I'm not sure what the best utility to open this on OS X would be, though
I bet you can extract it in a terminal with
tar xvzf mystuff.tar.gz
but if you want a GUI solution, something like StuffIt may work.

(Incidentally, I should probably point out that there's a period on the
end of that first command line. Don't forget it; it's there to indicate
you want everything in the current directory.)

How about tar zcvf to produce .tar.gz ?
When I telnet here with Kermit it gives me some helpful hints about what is
taking so long: The Telnet server is not sending required responses:
WILL TERMINAL-TYPE
WILL NAWS
WILL NEW-ENVIRONMENT
WILL COM-PORT-CONTROL
Does this mean there is a software problem at grex?

re #274:
> Change to your home directory and type

What happens when the tar command tries to add ./mystuff.tar to
the archive it's building in ./mystuff.tar?
Another problem (well, not really a *problem*, but potential
complication is that when files are extracted from the mystuff.tar
file they'll be dumped unceremoniously into the directory where
the tar extract command is run. You ought to either tell the
user to extract in a fresh directory or else back up a level before
building the tar file, e.g.
cd ~/..; tar cvzf /tmp/grex_homedir_$USER.tar.gz $USER
(in most shells, anyway..)

Also, while tar is the most convenient archive utility for most
Unix users, PC and Mac afficionados may find zip to be more useful
for them (Mac users can unpack zip archives using UnStuffIt; I'm
not sure how well it handles gzipped or bzipped tar files.)

tar is nicer because it retains the perms info

I agree that tar is the way to go if you're going to be extracting
under Unix or a Unix-like system..

Based on other investigation I doubt it's a telnet- or telnet-and-ssh-
specific problem. The same 79 second delay seems to affect outgoing
SMTP connections, too, for example.

It's definitely a configuration problem or software error of some sort.

Something in inetd perhaps?

No promises, but it looks like I'll have some time on Friday to attempt
a back-up of grex. I hope folks can stand losing it for a day during
the week. ;/

From my reading of recent responses, there seems to be some questions, or
suggestions, inre what gull said in #274. What should I take as the
current consensus inre my ? in #273?

Re resp:277: The version of tar that Grex has is smart enough not to add
the archive it's creating to itself...as long as you *don't* use the z
flag. That's why I didn't use it as was suggested in resp:276. I
thought about telling people to create the tar file in the /tmp
directory, but I didn't for two reasons: There's not much room in /tmp,
and people would inevitably leave the file lying around there where
anyone can read it. I agree with your other comments.
Re resp:284: Any of the suggestions that have been given will work.
There's More Than One Way To Do It(tm).
