It should time out after a few minutes, and finish starting up.
Sendmail wants to see a domain name. You could just add a
domain name to your machine's name in /etc/hosts. That did the
trick for me. You could, of course, disable sendmail altogether.

Just one thing
I suppose you've read the /usr/src/linux/Documentation/Changes?
You did upgrade everything that was mentioned in there?
If so I'm really at my wits end.
You should perhaps try a new posting in a kernel related group.

Symlinks are implemented in the filesystem; IBM's software doesn't even
need to know about them.
(Of course, it can explicitly look for symlinks and refuse to install, but
why would anyone do that?)

Subject: NFS can't recurse directory as user
Date: Fri, 16 Mar 2001 08:07:35 -0600
Hi, I'm using NFS to share files from a linux workstation to a linux
server.
The server is using v2.
My /etc/exports file is like this:
/usr/public (rw,all_squash,anonuid=99,anongid=99)
/usr/public 192.168.1.2(ro,secure)
/mnt/cdrom zeus(ro)
>From the client machine I have an fstab entry that looks like this:
hades:/usr/public /mnt/hades nfs defaults 0 0
So at boot time, server:/usr/public becomes client:/mnt/hades
The problem I run into is that I can't write to any sub directory under
client:/mnt/hades unless I'm root.
I can create a directory, but I can't write into it. Initially, my
/etc/exports file looked like this
/usr/public (rw,no_root_squash)
...
And after ready the man page found out that for a user to have rw
permission, you need to have the same uid and gid so I created a user on
the server but it didn't work.
anyway that's where I'm at ...
I have tried replacing defaults with user,rw but to no avail.
Thanks

Subject: Problems with Jdk1.3 with kernel 2.4
Date: Fri, 16 Mar 2001 09:08:42 -0500
Last week I was running RH 7.1 beta with Sun's JDK 1.3 just fine on my AMD K6-2.
The only tweaks required were a symlink (or copy) of /bin/cut to /usr/bin/cut and the
usual PATH and CLASSPATH stuff.
Over the weekend I put together an Athlon (old-style slot A) box and re-installed the
OS and JDK (rpm), as well as the same little /cut and PATH/CLASSPATH tweaks.
Same stuff as before.
Weirdness: In the terminal window I can "javac" my little test "Helloworld.java" file
to a class no problem, but when I try to "java" it, it just hangs and requires a Ctrl-C
to get the prompt back. This same little file works on the Windows side just fine
(as it has in the past).
Doing "which java" shows the proper path. Doing the full path like
"/usr/java/jdk1.3/bin/java -version" also just hangs.
Doing "/usr/java/jdk1.3/bin/java -verbose" shows a long list of opened and loaded
libraries which eventually hangs after:
[Loaded java.lang.ref.Finalizer$FinalizerThread from /usr/java/jdk1.3/jre/lib/rt.jar]
.. and requires a Ctrl-C to get the prompt back. I have also tried tweaking my
PATH and CLASSPATH everywhich way.
Anyone have any suggestions on this? Geez, could it be something to do with the
kernel/jdk and Athlons? (unlikely)

You *can* (see ldconfig, and useful info in other replies) but you don't
*have* to (you can use LD_LIBRARY_PATH when running the application).

IIRC in Win32 you don't register DLLs unless they implement COM objects
or plugins or codecs, thus are loaded at runtime by applications that
fetch their locations from the registry. For non-registerd DLLs, they
are looked for in standard places. See the doc for LoadLibrary.

The *name* of the DSO will have been specified at link time. The *path*
is determined at runtime. The man pages explain it much better than I
ever could!

found the program I had used before: gcdmaster --it's a

Unfortunately about half-way through burning a CD (in simulate

wide->narrow SCSI conversion is flakey. I think I'll add a
second (narrow) SCSI controller for external stuff like the CD
burner, and use the wide one only for internal (wide) drives.

Hi all,
I am using LM7.2. I found that when I try to install some
packages, I have never succeed! The problem is in the ./configure step,

My second question is still the upgrading of glibc2.2. there are so many
dep. problems e.g. for my currect gnumeric, it needs a lib in glibc2.1.x
which is not provided by glibc2.2. However, the new gnumeric needs
another lib provided by glibc2.2 only but not 2.1.x. Should I force it?
Thanks a lot.

WOW! you should read some of the other NGs.
I had exactly this problem yesterday -
I discussed it with Dean Thompson on comp.os.linux.networking
As I discovered, sendmail needs a full domain name for
whatever you have set for your hostname. It will wait for
2 minutes if it can't find it (I don't know what its waiting for).
So you have a choice:
1. Put a fake domain name in your /etc/hosts file
2. Disable sendmail (remove it or just remove the startup link in /etc/rc.d/rc#.d)
3. Find something else to do for 2 minutes while booting.

i am currently in the process of writing an admin tool that deletes accounts

just making each line an alias or even making each address it finds an
alias. my boss had mentioned that there was some way to poll the address
with some system calls and make sure it at least exist but was not sure
about the implementation or details. does anyone know anything about this,
or can anyone point me in the direction to do something like that. if not
do you have other suggestions about how to get only the email addresses out

Date: Fri, 16 Mar 2001 10:52:52 -0500
I've read the hard drive howto, and I am still unclear. Here is my
question:
Does it matter that the BIOS in my Nec Versa E (circa 1992) can't
handle a 10 gig drive if I am using Linux exclusively on the machine?
The way I read the howto, all I have to do is make a 5meg first
partition as the root. Is this correct? If I make the first partition 5
meg, will the installation system find another partition and use it if
I mount the second partition with /root as the mount point?
Need I even do all this if I am only using Linux? Can I, in other
words, make the first partition 5 gig and still expect the BIOS to find
the master boot record in the first 1024 cylinders?
