Hello,
Does anyone know any FTP server capable of authenticating users against
a LDAP (Lightweight Directory Access Protocol) Server?
Thank you very much.

What do you mean by "not technically"? Not legal, perhaps? Anyway, where
can I find information for these things? It was amazing that the
documentation for RedHat Secure Web Server did not include license
information.
Thank you.

I know Red Hat Linux 5 comes with a Novell 3.11 server called Mars_NWE.
enable the daemon by running ntsysv under RH5 and edit the /etc/nwserv.conf
to customise. This will require the IPX module loaded, check your boot
messages. You will need the dos files login.exe and every thing else that
netware needs to be put in a directory (cant remeber which)

Date: Thu, 22 Apr 1999 11:33:50 GMT
I have this specified in my ~/.ncftp/macros for a particular a kernel mirror
site:
get -n 15 patch-2.2.*
This tells ncftp to download only files beginning with patch-2.2 that are no
more than 15 days old.
However, when I ncftp -L -a to the specified ftp site, the macros get executed
okay, but 'get' was *trying* to download files much older than 15 days.
Already have patch-2.2.5.gz.
Already have patch-2.2.5.gz.sign.
Already have patch-2.2.6.gz.
Already have patch-2.2.6.gz.sign.
,... even though patch-2.2.5* are dated March 29 and today is April 22,
definitely beyond 15 days. It did though saw that patch-2.2.4* are older than

Is making up of virtual server as easy as it sounds?
I only got one IP, I just give aliases as many as I want eg
dom1.com dom2.fi etc. Do an alias file for sendmail, call for my ISP to
route
dom1.com etc to this one IP and that's it?

The top two and bottom two are fine... *great* infact, pppd adds and drops
the routes 100%... but the middle two *will not go away* and affect about 2%

Typing: "route del 192.168.0.0" or *any* derivation of that gives the error

It appears that you have your WIn98 box configured to log into an NT
domain, not a DNS issue. Open network properties, then check the
properties of the Microsoft Client. Uncheck the domain logon option.
The other alternative is to configure your Samba box as a PDC
(currently not the easiest thing to do), but remember that you will
have to activate encrypted passwords in Samba.

Subject: 2 NICs, 2 IPs: how is it determined which one is used?
Date: Thu, 22 Apr 1999 10:54:38 GMT
I'm using a Redhat Linux with 2.2.6 kernel. I have 2 nic's and thus
two IP addresses. One address is for the private lan, one for the
net.
Now, I'm having serious problems on another fields - of which I posted
a message here and to no one bothered/could answer. But the bottom
line of it was:
Connections to the world are made from my private lan IP and
unnecessarily masqueraded.
So the question becomes (to simplify it): how do you change which IP
of multiple ones is tried first? Or where is that decision made made
(kernel)?

The way it was explained to me was that if the 'wrong' processor tried to
access a value (one that was not it *it's* cache), it would not be able to
and would effectively do nothing (hence the insertion of the noop to make
sure the 'other' processor got the instruction). That never made any sense
to me [the 'wrong' register is always going to contain *something*, and how
the hell is the CPU supposed to know it's not the 'right' value], which is
why I've always thought of SMP as a load of crap. Now it seems that
explanation didn't make any sense to me because it just doesn't make any
sense.

*That* makes perfect sense to me now, and I think it also explains why my
manager (and by consequence I) was confused. I know he knows the difference
between threads and instructions, but he probably doesn't know the difference
between instructions and interrupts.

Thanks a lot for this mini-primer. I'll stop bashing SMP now. :)
