Subject: Problem with netgroup in /etc/exports
Crossposted-To: comp.os.linux.networking
Date: Sat, 11 Nov 2000 17:18:38 GMT
I'm setting up a Linux server at work where we use netgroups in our
/etc/exports files (HPUX and Solaris). According to the man pages,
Linux should be able to use netgroups in /etc/exports as well, but I
can't seem to get it to work.
I've tried RedHat 6.1, RedHat 6.2, Mandrake 7.0 and Mandrake 7.1 with
the same problem (shown in transcripts below). I'm exporting from a
Linux machine, I'm trying to mount on Linux, HPUX, and Solaris
machines, the results are the same with all three OS's.
I've searched with deja.com and found some others with the same
problem, but only two potential solutions. One was from back in '98
(concerning RH 5.2) where it was suggested that the poster recompile
all of the nfs utilities with the netgroup option turned on. I did this
under RH 6.2, even though the SRPM unpacked with this option already
turned on. It did not help. The other suggestion was to make sure that
/etc/nsswitch.conf had either nis or files specified for for netgroup,
which I have verified.
At work I'm getting netgroup via NIS, duplicating the problem at home
where I use NFS, but not NIS, I'm trying /etc/netgroup, with the same
results.
"Managing NFS and NIS" (Hal Stern/O'Reilly, 1992) says that
/etc/netgroup is not used, netgroups have to be served via NIS. Some
deja.com searching showed that this was true of Linux under libc5, but
with glibc, /etc/netgroup is consulted.
Here is my setup (from home), and the results:
netgroup entry on ichabod:
all_hosts (zaphod,,), (flenser,,), (ichabod,,), (cerberus,,)
Working /etc/exports on ichabod:
/dp4 zaphod(rw,no_root_squash) flenser(rw,no_root_squash) cerberus(rw,no_root_squash)
/ zaphod(rw,no_root_squash) flenser(rw,no_root_squash) cerberus(rw,no_root_squash)
New (non-working) /etc/exports on ichabod:
/dp4 @all_hosts(rw,no_root_squash)
/ @all_hosts(rw,no_root_squash)
Runninf exportfs;
root@ichabod# exportfs -r
root@ichabod# exportfs
/dp4 @all_hosts
/ @all_hosts
Attempt to mount:
root@zaphod# mount ichabod:/dp4 /mnt
mount: ichabod:/dp4 failed, reason given by server: Permission denied
root@zaphod#
This mount attempt works with the original /etc/exports on ichabod.
Can anyone help?
Thanks!

Put it in .bashrc for each user.
You can also put it into /etc/bashrc although I am not sure this is read
always.

Your machine is only suitable for running as a terminal. It doesn't
have enough memory to run a graphics display. It doesn't have enough
disk to put any modern distro on (except slackware and debian).
It doesn't have enough cpu to do much of anything.
If you must use it, try putting an old slackware on it. 2.2 would be
ideal.

I have done fetchmail from cron using demand pppd. The demand pppd

But what percent (%) is free on that partition? A certain amount is
reserved for root (5%?) so things do not grind to a halt if a user uses
too much. Also the reply to another post about trouble accessing hda
mentioned a problem with the logrotate of Mandrake 7.1 eating
inodes. What does 'df -il' show for IFree?

2GB is enough for RH 5.2 (2.0.36 kernel)
I have RedHat 5.2 on a '486 laptop with 32 meg of RAM and a 1/2 gig
disk. No I don't run Netscape, but I do run X11. I use fvwm in MWM
mode, don't use gnome or kde. I do use g++, latex, xv, xf, and xdvi on
it. I am not sure if I have used gimp on this box. 1/2 gig is a bit
tight, but enough for my laptop, given *my* usage patterns.
I *have* used Netscape 4.51 AND gimp on a '66mhz 486 with 16meg of RAM
and a 2gig disk. A bit slow, but worked fine.

I read Peter's reply before relying to this and I am just going to agree
with his suggestion. You will need to compare with a working system to
see exactly what is broken. Also, next time, before you change the SUID
bit on everything you might want to double-check that the program indeed
does not need SUID.

Is the client IP and hostname listed in DNS or /etc/hosts of the server?
Sounds like there is a hostname or IP resolution problem.

Well, in my case (just bought one a month ago), the floppy had instead of
a driver, a .txt file that gave the (old) URL for Becker's updated drivers
page. It was a little bit annoying since the URL they gave 404'd, but I
just tried the root page at cesdis.nasa.gov, which helpfully pointed me to
scyld.com where the new driver site is.

Once I compiled pci-scan and tulip as downloaded from Becker's site (mostly
trivial -- the only complication being the necessity of having modversions.h
accessible, so don't do a "make clean" after compiling the kernel), it has
worked just as well as older LinkSys cards have for me.

Unsure about that. I know the stock 2.2.17 kernel (as available in Debian
unstable) does not contain the latest version of tulip.c, and I haven't
ventured into the 2.4.pre* area yet.

The Perl Telnet module which is available from any CPAN mirror or
www.perl.com is known as Net::Telnet. You might also want to take a look
at rsh or ssh (encrypted) which can run remote commands.

It is possible that finger runs as or changes to an effective uid of
something other than root for security reasons. Have you checked the
finger results when run by user other than yourself? The effective user
needs the 'x' bit set on a dir in order to access anything in it. For
example in order for an apache user's public_html to work, their home dir
needs at least 711 permission.

Hi Mark and All,
I had found that my Linux 6.1 system did not
have the module smbfs.o. A suggestion on the newsgroups got
me to check. I had transferred a hard drive from a 586 system
to a 386 system and I had to recompile the kernel. Somehow
that module did not get produced. As a quick and dirty method,
I extracted the module from the 386 kernel rpm on the Redhat 6.1
CD.
