Subject: Peculiar behavior of usernet on RedHat 5.1
Date: Mon, 29 Mar 1999 23:21:57 +0000
Perhaps someone can explain what I am observing with the usernet utility
undre RedHat 5.1.
I am using usernet to allow any user to start up a ppp session. In the
past everything worked well and the usernet window would appear with the
indicator changing from red to yellow to green as the connection
progressed.
However recently, when I bring up usernet and start a ppp session, the
indicator goes from red to yellow and never changes to green--yet the
conection is made and everything appears to be working.
This behavior only occurs when usernet is started from a user account.
The indicator never turns green regardless of whatever ISP I am using.
Oddly enough, the behavior doesn't appear when I run usernet as root.
The indicator goes from red to yellow to green as I would expect.
Is this a setup or configuration problem? I noticed that usernet uses a
system service called netreport to get status information but never had
enough time to feret out what is really going on.
Can anyone give me a clue as to what is happening?
Many thanks.

Check out "Linux Network Toolkit" by Paul Sery, from IDG books. It comes

Linux box.

Hi,
How do you ring the bell on an arbitrary remote X server?
In this case it is an X-terminal that runs 1 display application
that runs under mwm where xterm has been disabled. The client host
will need to draw attention to the display. I thought there might
be an xbell sort of thing where I could direct the display to this
X server, but so far I can't find one.
Thanks,

An alle Novell- / Linux-Cracks,
ich habe SuSE 6.0 installiert. Netzwerk, DHCP, DNS,
Internet-Zugang mit IPPPD, Samba, MARS_NW,
alles l�uft fehlerfrei.
ABER,
wei� jemand, wie man IPPP zum Multiprotokoll-Routing �berredet, konkret:
IPX, Frame Ethernet_802.2
UND
TCP/IP, Frame Ethernet_II
�ber dieselbe IPPP-Verbindung?
Ich habe inzwischen ALLE mir bekannten RTFM's usw durch {:-[[
Die letzten Versuche haben auch nicht funktioniert. Ein Ping auf
die IP des remote Routers hat den Verbindungsaufbau veranla�t,
ich bekam immer ca. 4-6 Verbindungs-Zeilen und danach
keine Antwort mehr von der Gegenstelle.
Die ISDN-Verbindung bleibt aber offen, die IP-Routing-Tabelle ist ok.
Beim Blick in var/log/messages sieht man als letze Meldung nur time-out
beim Versuch, die IPX-Verbindung aufzubauen.
Ich vermute inzwischen, da� der IPPPD versucht, das IPX-Protokoll auch
an den Frame Ethernet_II zu binden und damit die schon �ber diesen Frame
laufende IP-Verbindung zerhackt.
Nehme ich die IPX-Optionen aus der /etc/ppp/options.IPPPx raus, gibts
keine Schwierigkeiten mit IP!
Der Remote-Router ist ein Hardware-Router von Bintec und IP / IPX MPR
funktioniert damit sonst absolut problemfrei.
Kann mir jemand helfen ?

True.

But the free software community is a testing/debugging in a massively
parallel way, with much lower overhead and redistribution latency.
Communication bandwidth between developers and testers is better, too.
All in all the free software model makes for faster and better fixing
of a greater number of bugs per unit of time.

Well, that may be true for sufficiently small values of "true" and a
value of "properly configured" that is much, much higher as the value
of "well configured"...

Subject: multiple ip#s on one machine
I have multiple ip#s on one machine for some virtual domains. The ip#s
are added at boot up with ifconfig. The web pages for all the virtual
domains work fine and dns is set up correctly for all the vitrual
domains.
I installed sendmail 8.9.3 and set it up to handle mail to/from all the
virtual domains and it works great except for one small problem. It
will not deliver any mail locally. If a user has a .forward file the
mail
is forwarded fine, if the email address is mapped to an external address
it works fine as well. But it refuses to deliver mail locally. Of note
is if you are logged into this machine, you cannot ping any of the other
ip#s on said machine. I can't imagine that this is "correct" or the way
it is supposed to be?
ifconfig eth0:2 208.247.139.186
Are how the ip#s are added in rc.local at boot up.
Questions:
Is it normal to not be able to ping any extra ip#s set up on a machine
in this manner? If not, how do I make it so the machine can see all of
it's IP#s?
Could the fact that you cannot connect to one of the extra ip#s be the
problem behind delivering mail locally? ie. you send mail to
[EMAIL PROTECTED]
and it goes to the paul.com ip#, sendmail translates this to the local
user
morgan, but cannot deliver it because it can't connect to the "real"
ip#?
But if the mail is translated to an address on any other machine it is
delivered without problems.
Any help anyone can provide would be greatly appreciated.

There's plenty of 'intelligible' info at www.samba.org and its mirrors, or
you can type 'samba' into most any search engine and find other sites and
pages that detail how different folks have set up and are using Samba right
now. Many, many people before you have managed to set up Samba with no or
little difficulty, and your inability to do so doesn't make these
instructions unintelligible.
You can also get an excellent book called 'Using Samba' from O'Reilly &
Associates; just look in the computer book section at any decent bookstore,
or go to amazon.com or barnesandnoble.com, or you can check out the
publisher's page at http://www.oreilly.com/catalog/samba/noframes.html
which, incidentally, can be found by simply using a search engine to do some
research on samba.

That's not a difficult task at all. I have a Linux box serving over 75
DOS/Windows boxes right now, and it works so much better, faster and more
reliably than our NT server, which has now been demoted to doing a single
department's menial tasks (for that MS geek who loves NT and just can't live
without it).

What sort of work are you expecting Linux to do? Will it be a print server?
File server? Email server? Usenet news server? Web server? SQL database
server? Have you taken the time to first figure out just what it is you want
to do with it, what you expect of it? And then taken that list and checked
to see if Linux/UNIX can indeed fulfill those tasks that you want done, and
in the ways that you want them done?
It sure doesn't sound like you've really thought this out, from what you've
written. First you talked about your Linux box being a server, then you
whine about your inability to find X11 or console desktop applications for
it. It sounds to me like you just picked it up and installed it because you
thought it was so cheap and you've heard all these neat things about it
(which are, incidentally, true even though you cannot seem to see it), and
started playing before you even looked into it to see if it would actually
work for you. Most business owners and managers actually take the time to
analyze the task first, then pick and choose the right equipment to get that
task done. You seem to be doing this backwards, which is not a wise way to
make a business decision.
>In all honesty, and without intending to offend anyone, Linux appears to

I think you need to spend a bit more time deciding what it is that you want
Linux to do, before investing the time and trouble needed to set up a
Linux/UNIX server. It's not a 'toy' at all, and you do it a great disservice
to call it one just because you have not been able to figure it out. It's
like calling a Lear jet a 'toy' because all you have ever learned to fly is
the Microsoft Flight Simulator, and you want to start flying now and don't
want to put in the time and effort to learn how to fly the real thing but
can't seem to get the damn engine started, much less actually get the plane
off the ground.
Because you can't seem to get a grasp on Samba but more importantly Linux
itself, you're whining and moaning like it's Linux's fault, or worse yet,
the readers of this newsgroup's collective fault! Take some personal
responsibility, man!
>this project. Although I believe I would have served my purposes much

And perhaps NT would be better for you. You're the one who has to make that
decision. But you need to better analyze your needs first before trying to
make an intelligent decision, unless you make all your business decisions
this haphazardly.

Oh, please, don't do it. Oh, please. [snicker]
C'mon, give us a break. Threatening to format your drive unless you get some
help here and now? I think that you didn't do your homework, and you're
stuck now because you're clearly in over your head with a real operating
system now, and just want someone to bail you out because you can't be
bothered to take the time to read and understand, to learn things for
yourself. Expecting to get good support from irc or a newsgroup is
unrealistic. If this is the way you run your business, I'd be surprised if
you're still in business in a few more months.
Either buy a commercial UNIX with a help desk to call, or go back to
DOS/Netware/Windows, or actually take the time to learn Linux. But whatever
you do, quit your bitchin' and moanin' and pissin' and blamin' others for
your own lack of knowledge, research, initiative and responsibility.

You need to give us more information, like the content of /etc/lilo.conf.
You definetely don't need to fdsik your system. If you have redhat installed,
you can use their boot disk to boot the computer. Insert the boot disk in, and
when you get to the ifisrt prompt, choose rescue. From there insert the resque
disk in and tyep rescue root=/dev/partition_with_linux (e.g. /dev/hda1). This
will boot you into linux and you can tango with lilo from there.

Maybe I'm displaying my ignorance, but isn't this essentially what
the ident daemon does? It listens to port 113 and responds to queries
about the UID owning a given port.

Subject: very slow networking problems
Date: Mon, 29 Mar 1999 15:20:15 GMT
I have a Dell OptiPlex GXPro (200MHz) with 64MB RAM, an integrated 3Com
vortex ethernet card, and Slackware with kernel version 2.0.33. Everything
has worked beautifully for the past two years, but last week, mysteriously,
telnet, http, ftp, smb, and probably all others are _very_ slow. Once
connected, there are very long pauses. For example, in a telnet session, it
will sometimes take minutes for anything to happen after pressing a key. When
telnetting in, the connection is usually instantaneous, but there is a very
long pause until the login prompt appears. In fact, the login will often time
out before the prompt appears. When I moved the server to a different subnet
and changed its IP address (to an appropriate one for that subnet),
networking seemed back to normal! On the original subnet, no other machines
that I know of are experiencing this kind of problem, including a
Sun(UltraSparc?) and Windows 95/NT workstations. In addition, I had (on the
original subnet) a test linux server with the newest distribution of Red Hat
linux on a totally different type of machine (an old Dell 433 with a 3Com
Etherlink III NIC), and it suddenly became just as slow at the same time! So
it seems like this problem is only affecting linux machines and nothing else!
Could this possibly be a denial of service aimed at linux boxes? One other
note: The original subnet is outside our company firewall, and the one I am
not having the problem with is inside. Does anyone know what might be going
on? Also, any informational references would be _greatly_ appreciated!!!
Thanks in advance.
