Space on Nyx is
inexhaustible (what else is new). This file
details what is considered acceptable and unacceptable usage of disk space. It
explains what will happen to your files if you don't follow these guidelines!
As stated in the "welcome" mail message,
500k is the recommended
. This should be fine for keeping the small amount of configuration files
that are typically needed.
Web space is limited to 2 MB
Your personal dir is for convenience only. It is NOT meant for you to keep all
worldly files. Nyx is not your personal closet, to store unneeded files.
Nyx does have "temporary" file space
-- make yourself a
directory in /nyx/temp1 by running /nyx/bin/mktemp. An easy way to make and use
directory is to use the 'ct' and 't' options in the 'u'nix file menu. The first
(do only once) and 't' moves you to that directory (do before ftp'ing, etc.).
[Note: do NOT use /tmp, /usr/tmp, or /nyx/tmp -- User files in there are
INSTANT removal (indeed, there is an hourly job that removes files from there).
directories are only to be used by programs like editors, mailers, etc. for
short-lived temporary files.]
Your temporary dir (that you create with the 'mktemp' program) is where you
large files, such as files you've ftp'd but haven't downloaded yet (just cd
starting ftp). Users working on projects for Nyx itself (installing new
software) can get
a dir in /nyx/projects by asking for one.
As the name suggests, temporary space is for *temporary* material, not items
to keep forever. Files in the temp dir are wiped out automatically after a
Note that you can find out how much space you use via the 'du' and 'du2'
options in the
status menu ('du' and 'du -a' commands from the shell). A periodic list of
'pigs' may also
be posted. You'll probably get nasty mail if you show up on this list.
Read your mail immediately, or at least save it off the mail spool to your own
directory. Do NOT send large amounts of data by mail (either sending or
receiving). Do not
use mail as a replacement for 'ftp'. Do not join mailing list if you aren't
going to read
Mail is subject to removal -- and note this is NEW mail, not old i.e.,
"saved" mail (which comes under the heading of home directory). If
you join a
mailing list, post a note to nyx.misc asking if others are also on it; if a few
it, I'll make a newsgroup for it and each reader can drop off the list (so Nyx
copy instead of N).
With all that in mind, here is The Policy:
If you exceed 300k in your home directory, all your files (ALL of them) will be
out. This policy has become necessary since users ignored the voluntary
previously imposed, and continually filled up the disk. When the disk fills up
it locks up
When space gets tight, as it inevitably does, users with the largest amount of
will get the deleted until we have enough space left.
To avoid file buildup, files older than 10 days will be automatically removed

out all the files in the N largest directories.)
Do not try to circumvent this, or you will lose the temp dir privilege.
Users working on projects can get a directory in /nyx/projects; tell us which
and we'll make the directory.
Files in /tmp, /usr/tmp, /var/tmp, /nyx/tmp are subject to instant removal; in
practice, files are removed by a job every 4 hours and directories are removed
Don't use them for your own files, period.
Incoming mail ("mail spool") file:
Any mailbox larger than 1Mb is subject to removal if the last read date is more
day ago OR if space is very tight (in which case it is subject to instant
Any mailbox larger than 50k and unread for 3 days is subject to removal.
Any mailbox larger than 10k and unread for 7 days is subject to removal.
Any mail file that is deleted will be replaced with a mail message containing
of users the mail was from (generated automatically via the Unix 'from'
mail will not be saved anywhere else.
General guidelines to keep your usage down:
- To see where your space usage is, use 'du' or 'du2' options from the info
shell: du, du -a). If .newsrc is large, remove groups you don't read (run
also on news menu).
- Use the 'u'nix menu's 'ct' and 't' option -- your temp dir. (/nyx/bin/mktemp
from the shell.)
- Remember to remove files after you download them.
- Remove files you don't need (download them, for example).
- If files are of general interest to other users, upload them (use the command
copy file1 file2...'); In the menu this is in the 'upload' menu. Then remove
- If you have programs you use on Nyx, have them installed where everyone can
(talk to the admins, email@example.com, about it). Then remove your copy.
- For mail: - Don't subscribe to mailing lists you can't keep up with - Post
you get to nyx.misc; common ones can be made into local newsgroups - Cancel
if you're going away - Don't send files by mail (ftp them) - Read then delete
your mail -
Forward your mail to another site (make a file named ".forward"
other address and TEST it!).
