Hi to everybody !
I have a problem creating a login script in
kppp. My situation is the following:
1. I'm connecting my computer to an ISP who then connects me to the
other computer which is
my real ISP. This looks like when I connect to the firs comp. I have
to isue at the username
prompt the "kiss.uni-lj.si" and the first comp starts the ppp which
then conect me to the second
comp. which then verify my Username an Password. Can somebody help
me how to make a
script in kppp ?
2. I try to use kppp with the terminal-prompt but it seems that the
computer i'm dialing in does not
support the V120 so only grbbed text apears on connect.
Any hel apreciated.
Thank you in advance
Sasa

The cards work fine using the tulip driver. However, there are
second revision cards out there (the ones with wake-on-lan
support) which you might need a modified driver for. Linksys
actually _provides_ the driver on their website! They are
giving _excellent_ support to the Linux community IMO, and
deserve our patronage.

If you don't get it, then you need to do some reading about
switches. Low end, cheaper switches are fine for smaller
networks, but for those times when you really NEED the
management, then those switches don't cut it.
We use a Cisco switch because of the management features ---
price was not a serious consideration, although considered.
We needed that.
At home, I run a small network, on a cheap switch --- it is
better than a hub, but it doesn't have any management. For
that situation, it is fine.
So basically, you have to define the problem before you can
pick the hardware.

You need to supply more info. Did you 'make modules' and
'make modules_install' after making the kernel image? Can
you see the 3c509.o file in '/lib/modules/2.2.11/net/' ?

I have run this ssh client and also the Datafellows one together with Exceed and
Xwin-32 without any problems. You have to mark the checkbox "Forward X" in the ssh
client. No need to redirect the output like you do with telnet for example. You may
have to put the machine you log into some kind of xhost file for the X server
though.
What has been the problem?

Subject: Internet Mail setup
Date: Wed, 15 Sep 1999 16:28:36 GMT
Hi,
I'm submitting this post in the hope of helping anybody else who's been
stuck in the same boat as me. We have, up until now, been using Windows
NT to pick up our email from our ISP and then distribute it out to
ourselves when we dial into the NT box. I wanted to move this over to
Linux for all the usual reasons. (Not least being the fact that the
Linux box won't need rebooting every two weeks).
Anyway, the problems are this. Our ISP sends all our mail to a single
account, which we connect to with PPP and POP. We then need to
distribute all of the mails to the different internal accounts, and
serve out the mail internally using POP. (Via PPP, or over the internal
network). We also wanted to preserve the [EMAIL PROTECTED] format.
So, I implemented this with the following solution:
Arriving email from the ISP to the Linux box:
We dial up using the standard PPP connectivity. This was explained fully
in ISP Connectivity mini-HOWTO. This has proved the most straightforward
part of the whole exercise, although I have been dogged by routing
problems. However, only lack of time has stopped me from getting to the
bottom of this.
Once connected to the ISP, we use fetchmail to pick up the mail, using a
given mail account. However, all previous postings suggested then
passing the incoming mail onto the procmail. BEWARE, this method does
not support CC and BCC. It passes through incoming mail once and passes
it off to whoever needs it. That's it. This wasn't much use as we often
receive incoming mails for multiple addresses. So, in the .fetchmailrc
file I didn't specify the mda (mail delivery agent). This works fine.
All aliases are specified in the /etc/aliases file and work no problem.
Outgoing mail from the Linux box to the ISP:
This was difficult to get going until I sorted out the routing and put
the domain in the relevant file. (/etc/resolv.conf I think). However,
once done, I just do a sendmail -q when the system comes up and all mail
is gone. (I think that I should be doing sendmail -qdomain.com for
secutiry reasons).
Incoming and Outgoing mail from external users to the Linux box:
This required the mgetty package to be installed. (I'm running Redhat
V6.0). Thereafter, it was fairly easy to set up, using the necessary
files in the /etc/ppp and /etc/mgetty???? directories. Couple of
gotchas, though. Beware of not confusing the ppp options files used by
the incoming dialin users, and the outgoing connection to the ISP. (Had
a few problems when I was trying to force my designated remote IP
address onto the ISP !)
I use AutoPPP with PAP verification, which works fine. Beware here that
you can't stipulate all of the pppd options in the login.config file
itself. You have to say something like "pppd file filename" and the
filename contains all of you options. (Pulled some hair out on this one
!)
For the picking up of mail, the users access the Linux box via POP. This
was setup by just enabling the service in the /etc/inetd.conf file. It
automatically starts up when connected to.
So, that's my setup ! I've sent this in the hope it may help out some
other poor soul trying to achieve the same thing, if only for the
knowledge that it is do-able. The FAQ's and HOWTO's are an invaluable
source of information and guidance, as is Dejanews, although many of the
Dejanews posters have an irritating habit of saying "yeah, that's easy,
all you need to do is to enable the ????????", and then not saying HOW
you enable the ????????. But, then again, we're not paid for doing this
and the advice was, more often than not, spot on.
If I can help anyone by posting any cfg files, such as ny sendmail.cf or
whatever, just let me know.
Good luck !!
Mike Ryan
PS I hope I didn't make this sound easy. It took me an awful long time,
and I have learned far more about sendmail than I ever wanted to.
However, I now have a solid mail delivery system that I can fully debug
and rely on. Next stop IP Masquerading !

The client would need to support ip forwarding, and your X server
would need to be set up to allow connections from the localhost.
Looking through the strings in the above-mentioned ssh client seems
to indicate some support for X forwarding.

There is no single answer. One size definitely does not fit all.
The original poster simply asked "what's best". To answer that simply
by naming a brand/model would be incredibly irresponsible.
For example. Imagine two different LANs:
LAN 1 is a small/home office with about 10 devices (computers, maybe a
few printers), and 5-6 employees. There's no real need for security,
because everybody knows everybody else, and the amount of bandwidth used
is pretty low, because all the access is just grabbing files from a
server and printing them.
LAN2 is a mid-size corporation with 300 employees and 1000 network
devices. Management is concerned with security, and some people/servers
consume large amounts of bandwidth throughout the day.
A cheap $150 unmanaged layer-2 switch would be just fine for LAN 1. It
would be quite useless for LAN 2.
A $15,000 layer-2/layer-3 switch with over 100 ports, SMTP management
and other features would probably be a good idea for LAN 2. It would be
a colossal waste of money for LAN 1.

Excuse my ignorance here, but I'm not seeing that on my boxes.
I've got a RedHat 2.5 box (kernel 2.0.36) here. It has one Ethernet
adapter configured for 10.1.1.2/255.255.255.0.
/etc/sysconfig/network-scripts/ifcfg-eth0 contains:
>>>>>>>>>>
DEVICE=eth0
IPADDR=10.1.1.2
NETMASK=255.255.255.0

ONBOOT=yes

/etc/sysconfig/network contains:
>>>>>>>>>>
NETWORKING=yes
FORWARD_IPV4=false
HOSTNAME=myhost1
DOMAINNAME=

<<<<<<<<<<
When I run netatat -rn, I see:

So what am I missing here? Looks like all the default routes are
automatically created at boot time from the network configuration files.
I never wrote a single "route add" line.
I've got another 2.0.36 box with three ethernet adapters, and forwarding
packets between the three attached subnets. Again, I never explicitly
added any routes. Since there are no networks beyond the directly-
attached ones, there is no need to add any additional routes. (Some are
added on the attached workstations, of course.)

Subject: NFS problem for RH6.0

Reply-To: [EMAIL PROTECTED]
I try to mount Linux from Solaris 2.6
using NFS, but I can not succeed.
I get a message : NFS service not
responding. I check the nfsd, it is
up with state SW. I put the following
line in the /etc/exports file
/home hostname(insecure)
and then run /usr/sbin/exportfs.
By the way, if I run
/usr/sbin/rpc.nfsd I get a message:
nfssvc : Address already in use.
My rpc.statd and rpc.mountd and
rpc.rquotad are all sleeping there.
But
I don't have rpc.nfsd in the process.
Is this the reason why I have
problem?

One addendum to this. Just because a hub is 10/100 switchable, doesn't
mean that if you plug 10 and 100 cards in, that it will run at the card
speed. You need to make sure that the hub is n-way switchable which
means it will allow both 10 and 100 mixed but running at the fastest
speed the card allows!
Linksys products are excellent and deserve the linux communities
patronage as they have provided linux drivers for their cards for quite
some time.
