Hi Hans,

I do authentication against MySQL with Courier. Unfortunately, Courier 
from Suse 10.1 has no support for MySQL auth. If you don't mind 
compiling, you can add the missing pieces.
To ease maintenance, I modified the courier-authlib specfile, using the 
'original' (from Double Precision, maintainers (?) of Courier) spec-file 
and made an rpm for courier-authlib-mysql.
After that, you have to make an authmysqlrc file in /etc/authlib. 
authmysqlrc is documented in postfixadmin, I think.

Hope this helps,
Koenraad lelong.

Yes.
Not only "some kind of driver" but actually "the right driver".

See for example:

It doesn't matter which kind of network protocol you use
(SMB, LPD, IPP, whatever) to transfer data from Linux to Windows.
The crucial point is that a usual Windows system (without additional
special software) cannot convert generic PostScript, PDF, JPEG, or
whatever stuff which is to be printed into printer specific data.

FWIW, that special software could be Redmon 
(http://www.cs.wisc.edu/~ghost/redmon/ seems down for the moment). I 
used it to make a non-PCL printer accept PCL, but you can make it accept 
PostScript also.

[opensuse] Wireless setup [OT]

2007-01-23 Thread Koenraad Lelong
Sorry for the off-topic post, but I don't know where to ask, so any 
pointers are welcome.
At home I'm trying to set up a wireless accesspoint (connected to a Suse 
sever, that's why I ask here ;-) ). If the accesspoint is placed inside 
the house it's impossible to get access to it. I tried with two 
different products (Linksys and D-Link). Those accesspoints do work fine 
elsewhere, even in my gagage, which is a different building than my 
home, max. 20m away, but from inside my home I can't connect. I tried 
all channels, with no luck.

So, has anyone of you some hints what to try next to get connected ?
P.S. as far as I know there are no other transmitters in that band 
(2.4GHz ?) at home.

Do you have a cordless phone?

A lot of them are in that band and will interfere. We had to buy a new
cordless in a higher band.


Yes, DECT should use the band from 1880 MHz to 1900 MHz, but ETSI allows
2400–2480 MHz which can cause trouble. If your wlan router and your wlan
cards allows you to choose channel 14 (normally available in Japan) then
you have a good chance that they are not overlapping. I'm not sure if
this helps, but you can also adjust the burst-rate at the wlan-router.

Furthermore it helps to look for other radio-emitting (phone, microwave,
ham radio) devices that stand closely to each other (to the wlan
router). Try to place them at least 12,5cm away from each other.

A next good guess would be to look what objects are standing close to
the wlan router, because of reflection, refraction and interference it
is possible that the transmission waves are razed.

Patrick


Thanks for those suggestions, but besides some cell-phones (not near 
laptor or accesspoint) we don't have any wireless (radio) devices, and 
the microwave oven is meters away and inactive at most of the times of 
my tests.

I'll look at the burst rate and give it a try.
I tried at least five different locations in the house but except for 
one these were on or in open wooden closets, next to a wall. The other 
one was on the table max. 1 meter away from my laptop. I'll try on a 
different table farther away.

[opensuse] Avoiding spam to harvested addresses

2007-08-27 Thread Koenraad Lelong

Hi,
Recently I started receiving spam to a mail-address I setup for a list. 
To get rid of the spam I removed that mail-address so that's solved. 
Crude, but it works.
But then I read Sandy Drobic's post from 22/8 about those bounced mails 
from this list ("Why do I get this back all the time"). He mentions that 
he setup his system to reject mails not coming from the listserver.
Where in the Postfix documentation should I look for information about 
setting this up ?

Thanks.

If it is, in fact, an ALC883, then check out the posting I did on Linux

I just got a new PC, with an ALC883 codec on the MoBo. I downloaded the

I also tried 10.3Beta3 on it, and then it works 'out of the box'.

You will need to install it manually. If it was installed with an rpm,
uninstall it, and the download nvidia-installer, and run it. You will
need to have kernel-sources installed in order for this to work, as it
will need to build the kernel module.

Read the README on the download page.


I installed with the nvidia-installer. Seems to work fine now.

[opensuse] RDP through firewall

Hi,
I would like some "external" users to have access to a W2k3 server via 
RDP. Between the Internet and our intranet there is a Suse 10.1 machine 
acting as firewall (Susefirewall2).
To get access to the W2k3 server I added a rule in the firewall via 
Yast. When I look in sysconfig I see in FW_FORWARD_MASQ :

source-network : IP of client (what if this is dynamic ?)
IP to forward to : IP of W2k3 server
protocol : TCP
port : 3389
redirect Port : 3389
destination IP : IP of external NIC

Any comments before I try this ?
Maybe I should use FW_FORWARD ?

Re: [opensuse] Keeping 2 or more machines up-to-date, without wasting bandwidth

2007-09-25 Thread Koenraad Lelong

Sylvester Lykkehus schreef:

Hello list,

This question has puzzled my quite some time.
I have 2 machines, both running openSUSE (10.2)
They have different purposes, and therefore are quite different in 
amount/selection of installed packages.


I use (and is a big fan of) smart to keep both machines up to date.
They both have the same repositories added.
Even though the machines have different selection of packages, there are 
a lot of overlaps, for example KDE and Gnome are installed on both.
That means, when I do a 'smart upgrade', I will use 2x the bandwidth for 
the packages that the machines have in common.


It's not enough to just upgrade one, and snatch the packages from 
smart's cache to upgrade the other, since PC1 might not have gotten all 
the upgrades that would be available to PC2 as well.


Can anyone come up with a good solution to this problem ?
It's not a big deal for 2 PC's, but I could see it be useful, if I added 
a couple of more PC's to my lan.


I was thinking something like a third machine (or one of the already 
connected PC's), gathering a list of needed updates from all of the 
PC's, then download the packages needed, and serve them (over nfs for 
example) to the other PC's to grab as needed.


I could do this with a bit of scripting, would it be a feasible 
solution, or can anyone come up with something better ?


Best regards
Sylvester Lykkehus
What I recently did is sharing (NFS) the whole smart data-directory on 
one machine and point the other machine(s) to that shared directory. As 
long as you don't try to update at the same time on different machines I 
think this should work.

Of course you have to configure smart to not delete the rpm's.

[opensuse] stunnel certificates

2007-05-30 Thread Koenraad Lelong

Hi,
I want to secure access to a databese server (Firebird). I want to do 
this with stunnel. I'm having troubles with the certificates. This is 
what I did, using standard Suse 10.0 stuff (I modified openssl.cnf to 
have a number of defaults) :

#in a clean directory create structure :
mkdir demoCA
mkdir demoCA/private
mkdir demoCA/newcerts
touch demoCA/index.txt
echo 00 > demoCA/serial
#Create CA files
openssl req -new -x509 -keyout demoCA/private/cakey.pem -out \
 demoCA/cacert.pem
#Create server key & signing request
openssl req -nodes -new -newkey rsa:1024 -keyout server.key -out \
 server.req
#sign server certificate
openssl ca -policy policy_anything -notext -in server.req -out \
 server.crt
#Create client key & signing request
openssl req -nodes -new -newkey rsa:1024 -keyout client.key -out \
 client.req
#sign client certificate
openssl ca -policy policy_anything -notext -in client.req -out \
 client.crt
cp demoCA/newcerts/00.pem /etc/stunnel/server.pem
cp demoCA/cacert.pem /etc/stunnel/cacert.pem
chmod 740 /etc/stunnel/server.pem

My stunnel.conf is :
client = no
foreground = yes
debug = 7
verify = 3
CApath = certs
CAfile = cacert.pem
cert = server.pem
[firebird]
accept = 3051
connect = localhost:3050

When I try to start stunnel I get :

This procedure is an adaptation from a document from the Firebird 
community. What am I missing ? I think the Diffie-Hellman stuff can be 
ignored.
I tried three other documents (from the stunnel-site) but these don't 
work either (for me ;-) ).
Anyone can give suggestions, tips, links ? They will be very much 
appreciated.

Are there other methods ? I don't want to give ssh access to the users.
I know of zebedee, but this seems old (unsupported ?).

Well, I tried another howto, about adding TLS support to Postfix, which 
worked for my mail-server. But this didn't work either for stunnel. 
Finally I combined some howto's and I got partial success.
One has to append the private key, the certificate and "Diffie-Hellman 
parameters". Each section has a blank line between them. And the last 
line is also a blank line. I did it this way :

cat server.key > server.keycrt
echo \ >> server.keycrt
cat server.crt >> server.keycrt
echo \ >> server.keycrt
openssl gendh 512 >> server.keycrt
The server.keycrt is the cert stunnel uses.
With partial success I mean I can connect if I don't check the client 
certificate at the server (verify = 2). I believe the server can't find 
the client-certificate, but I don't know why. Anyone knows how to see 
which file an application tries to open ?

[opensuse] Migrating users to new machine

Hi,
I'm planning to replace a samba-server acting as PDC now running 
Suse9.3. For this I need to migrate all users, retaining their UID and

The home directories will be made first (restore from backup).

from the old machine to temporary files on the new machine and editing 
/etc/passwd, /etc/shadow end /etc/group of the new machine to copy new 
users from the old files.

The rest is following "Samba by example".
And suggestions and opinions are welcome.

[opensuse] hosts file and Yast

2007-08-22 Thread Koenraad Lelong

Hi,
I have a stupid application that reads /etc/hosts and uses the 
IP-address where an alias is placed as the address to listen for 
requests. This is fine when there is only one IP-address on the machine.
My server has two net-cards and thus two IP-addresses. One goes to the 
Internet, the other to the internal net. Unfortunately, everytime I 
change something in the network-card configuration the external 
IP-address gets the alias. That's not what I want.

If I edit hosts to be like this :
...
192.168.0.1 box1.local.net box1
192.168.1.1 box1.local.net
If I change something in the network-card configuration with Yast, hosts 
ends up like this :

...
192.168.0.1 box1.local.net
192.168.1.1 box1.local.net box1
Is there a way to tell Yast to give the alias to the internal address ? 
I use Suse 10.2 B.T.W.

I hope this makes sense.
Thanks for any help you could provide.

I tried recording with Krecord, but it doen't record anything, I tried

I briefly tested it on Suse (don't remember the version though) when I

If you have a choice, look for something else. Prior to the REV we used
the Peerless. That worked great. So of course it was discontinued. We
now use basic USB disks like LaCie or Maxtor. They may cost a bit more
than a REV disk, but we reuse them as they are only for data transport.
For backups, they are perhaps more than you want to pay. Depends on how
important the data is.


Thanks for your vision. Like I said, I use it on a Windows machine, 
works fine. Backing up about 80Gb in about 4 hours over the network I 
find acceptable. But that's on Windows.
I do the same with some USB disks also on the Windows 2K machine, but 
there the disks sometimes disconnect for no apparent reason.

And another con is the size : a Rev disk is very small.
Anyway, I'm gathering information to virtualise some servers. I would 
like the host OS to be Suse. Maybe it will be Windows :-(

Thanks again.

[opensuse] SNMP software

2008-01-09 Thread Koenraad Lelong

Hello,
My router has snmp-functions and in the usermanual is written that this 
is "compatible with HP Openview compliant software".

Is there some Linux-software I can use to access the router ?
I played with net-snmp but I don't get anything back. I enabled snmp on 
another suse machine and from this I get answers on my queries.

CP1350AVRLCD UPS) under SuSE?


I use APC, because the explicitly support Linux, even
providing the Linux version of their powerchute program
on their website.

Right now I'm considering a new UPS. I used MGE (a sponsor of NUT), but 
they seem to be taken over by APC.
My question : do you protect more than one server with one UPS ? Does 
Powerchute provide information to the servers not directly communicating 
with the UPS ? What I mean is, when the UPS is exhausted, does the 
"master" server sends messages so the "slave" servers also go down 
cleanly (not just power off) ? "Master" meaning the server that listens 
to the UPS's status, "slaves" just get power from the UPS.

Can Windows be part of this setup ?
I looked on their web-site but I didn't find these answers, maybe I 
overlooked ?

In our company the ups is a bit bigger and includes a snmp card, so all
servers can query the ups directly and decide depending on their local
configuration if they should shut down or not.


I'd second everything Sandy said and add that it's not essential to have
an snmp card for multiple servers. apcupsd also has its own method of
distributing status to daemons on other machines. Use whichever is most
suitable for you.

Thank you both for this information.
