Hi all,



  I have similar problem.


  The only thing is that instead of installing from DVD, i put the DVD
  images on to a server which loop-back mounts the DVD. I have added=20
  the local server address to the sources.list.=20
  But on the Etch DVD there is no Release.gpg file.
  Now, how can i avoid the authetication warning without using=20
  APT::Get::AllowUnauthenticated 1




 OR


  can i download the GPG keys from the etch website and then have it
  installed in my machine so that i can avoid the authentication=20
  warning  ? If so can someone point me to the website and the method
  to import the keys


Do you need help?X

thanks

Dear each



Iceweasel is telling me that I have a missing plugin, the JRE, which I 
need for a course. I have downloaded jre-6u1-linux-i586.bin (which is 
the appropriate plug-in), but:


(i) is this the best thing to be using on a Lenny/Sid system and
(ii) if so, how do I go about installing a *.bin file on my system?



Many thanks

Extensively discussed here:
http://www.nvnews.net/vbulletin/showthread.php?t=90214

The problem is that post 2.6.18 Debian kernels have PARAVIRT_CONFIG and 
nvidia does not like that.

You can either rebuild the kernel and turn that off (Note: but in that 
case I had hard hangs in qemu!) *or* use the descriptions in that page 
to rebuild the kbuild .deb and install nvidia so it does not mind paravirt.

You'll hit the problem both with m-a *and* the nvidia installer.

I would first try to get it working for a normal user (see below).

Have a look at /etc/pam.d/login, you will probably see this:

# Disallows root logins except on tty's listed in /etc/securetty
# (Replaces the `CONSOLE' setting from login.defs)
auth       requisite  pam_securetty.so

AFAIK, this can block remote root logins even if sshd_config allows
them.

I agree with Kent that it is better not to allow remote root logins. 

It would be nice to have more debugging output from the client. Try to
run this on the Apple box:

sftp -v username@host

and post the output here. (Replace "username" and "host" as is
appropriate for your Debian system; you will be prompted for the
password.)

(I hope that OS X, being BSD based, still has the normal sftp utility.)

I've asked that question before and never got an answer.
I now use Sid and use a script to install all the packages.
That script now installs tetex and which apt replaces with texlive.

But my question was: how long before installing tetex will actually 
cause "package not found" because the tetex -> texlive transfer is not 
one to one. Where is there a description of what tetex package 
corresponds to the right texlive package?

Is this a typo? Etch IS stable, right?  And those of us running a
stable Etch with tetex should not migrate to Tex Live is how I'm
reading the last few threads on the topic.

My mistake, I meant to say when Lenny is stable. Etch is already
fixed, so no matter what happens in testing, you should stick with
what you've got in Etch -- if you're using tetex, just keep using it.

Hello,

I'm planning on restructuring our authentication services. Currently
they're a simple LDAP setup with posixgroups which afaik makes dynamic
groups impossible (correct me if i'm wrong, _please_ tell me how to do
that).

Googling around I found rfc2307biz, which makes in contrast to rfc2307
posixGroup an auxiliary group so that one could use groupOfNames to
build groups.

For those not knowing what this is about:

Using posixgroup you define group members with the memberUID (the loginname)
imho a better approach (but the rfc is deleted by the ietf, anybody
knows why?) to use the DN of a ldap object. This is very well possible
with groupOfNames but groupOfNames is missing the gidNumber attribute,
which is needed by libnss-ldap, and samba.

The quirk in debian imho now is that samba doesn't support rfc2307bis
schema and schema-mapping - it's simply compiled without it. wihle
libpam-ldap and libnss-ldap do support this schema.

Any way to get around that using groupOfNames (so that i can add one
group to another group and sleep well cause pam, nss and samba will
know how to deal with it). Or any other means, groupOfNames would be
quite comfortable cause intermediate tools could always check for the
existance of a ldap object with the given DN and thus check for
validility?

regards
martin

PS: if you know where it is better to better ask this question please
point me to it, imho that is very debian specific because it
specifically deals with the standard packages available in etch.

Testing-Etch was just fine; I started sometime between the last beta and
RC1.  I stuck with Etch when it went stable to avoid the flood of
pent-up sid stuff.  If the flood's over and the experience is as it was
before etch RC1, that would be fine.

Thanks,

Doug.

Yes and no.  For 99% of what I do, my 486 is fine.  Although, after
doing  a drive-shell game to get Etch on it (it only has 32 MB ram so
the installer doesn't work), its really much slower than sarge and
certainly slower than woody.  Text-mode scrolling (no framebuffer) and
cursor movement, as in arrow-down in mc or lynx, is jerky and slow.
OTOH, Net- or Open-BSD run great on it.  That 99% of what I do is
text-based.  Konquerer is too painful (the other 1%).  OTOH, now that
I've got an Athlon64 with 1 GB ram, and dual 80 GB drives (raid1 for the
system), I've got lots of room.  OTOH, Stuff just takes up more and more
memory.  OTOH, there are no other hands (from __Fiddler_on_the_Roof__)
:)

I use the nvidia driver for my en7300GT so that I can get a good picture
when watching DVDs.  I forgot about the lack of nvidia modules in
testing.

I already use TexLive.  What happened to your / partition?  How small
was it.  Is it only / or is it everything but swap and /home?

I can understand that anything like a dvi viewer may want Tex stuff but
not KDE in general.

Many thanks to all that provided their help.  Mostly I found easy to use
Thomas' suggestion:

.  Now, `readcd' would produce I/O error messages with *all* DVDs, also the ones
that I know for sure are all right.  So, it was actually not useful at all.
Instead, `star' seems to do the proper job: with Sarge I did:

 # apt-get install star

, then mounted the disk, then cd into it and:
 
 $ star -cPM . >/dev/null

.  With the damaged disk, it produced an output like:

 star: Input/output error. Error reading 'rodolfo-30.giu.2007/mobile/opensync/libsyncml/tests/.svn/README.txt'.


, then ended up with:

 star: 118167 blocks + 5120 bytes (total of 1210035200 bytes = 1181675.00k).
 star: The following problems occurred during archive processing:
 star: Cannot: stat 0, open 0, read/write 662. Size changed 0.
 star: Missing links 0, Name too long 0, File too big 0, Not dumped 0.
 star: Processed all possible files, despite earlier errors.

.  Instead, with the brand new DVD the output was:

 star: 119837 blocks + 9216 bytes (total of 1227140096 bytes = 1198379.00k).

.  So it seems that I can use this tool to verify disk integrity.  I didn't try
other people suggestions because this one was the simplest for me.  Only one
thing: the command `apt-get install star' does not work with Etch: it knows no
package named `star'.  Any suggestion about how to install star under Etch?

Thanks indeed,
Rodolfo
