Subject: PPP at 9600bps
Date: Thu, 18 Feb 1999 02:31:38 GMT
Hi,
I have a PPP connection problem (which I don't know how to solve
it). The link is connected by two modems; one is Hayes Accura 14.4k
and the other is Diamond Supra 33.6k. Due to the older model of the
motherboard which the Supra is connected, the maximum serial line
speed is 9600 (I have locked the pppd speed into that).
I use Linux Slackware 3.5 on both PC machines (Acer/486 and
Acer/586). The Acer/486 has an 2 16450 UART (which I believe
it's the source of the problem), the other one has a 16550A. The
2 I/O port was replaced by an I/O card yesterday, which
unfortunately had a 16450 UART. So, the problem persist.
Pinging using ping -i 2 would work just fine; the time didn't get
longer and longer.
ping:
PING bdg-gw.pindad.co.id (192.200.9.110): 56 data bytes

Please help me with some pointers. I think I configured the pppd on
each machine correctly. But finding out that I couldn't send/receive
(via ftp) files larger than approx. 20Kbytes was pretty distressing.
I believe that PPP connection can be established on 9600 bps links,
but unfortunately there are some things still missing.
Can this problem be resolved by setting the LCP parameters in
/etc/ppp/options?
Thanks in advance.

Does the card emulate any well known ethernet cards? For example ne2000? If
so you can use that driver under linux. You may have to configure your card
to a specific I/O address and IRQ number before your card will work. To make
setting changes to the card you will need to do it through switches on the card
or through a Dos utility set up disk that ships with your ethernet card.

hello ,
i Need to have a good firewall to protect my local network under linux.
Please where i can find a package easy to setup for that ???
At this time i've manually use ipfwadm but i think it's not perfect,
and just heard ipchains it's may be more flexible ...
Can you send to me any good ideas about this subject ?

Date: Thu, 18 Feb 1999 23:29:06 GMT
Mike,
I too am having similar troubles with my masq'ing Linux box. A couple
of things to try would be upgrading to a 2.2.x kernel as this now
includes router optimizations. Try compiling in the options:
CONFIG_IP_ROUTER
CONFIG_NET_HW_FLOWCONTROL
CONFIG_CPU_IS_SLOW
This helped a touch. Also try playing with your MTU and MRU sizes in
your pppd config file (possibly /etc/ppp/options). I have a value of
552 for both (512 bytes of data plus 40 byte header). These changes
may improve your situation. Mine improved slightly but if anyone has
any other ideas I'd be glad to hear of them. Just out of interest,
how much CPU time does IP masq'ing take up? My box is only a P133,
could a faster processor improve things further? I'd also be quite
interested in knowing if there is a seperate Quake2 module (of if
there is a need for one).
Hope this helps,
Robin

Going in the same vein...if one of the boxes is using a transciever
rather than a built in TP connection, make sure your SQE is ???. I
can't remember if it should be on or off if you're connecting to a
repeater (hub), but switch it if you can and see what happens.

FIXED! I fixed it, it was trivial. I didn't know that the pop servers
weren't installed by default. Once I RPM'd the IMAP package, all was
well.
Is this some sort of test that Red Hat puts in there?

Subject: Re: Help with Appletalk
Date: Thu, 18 Feb 1999 20:02:05 -0500
Okay, a little bit of education here:
Appletalk is a protocol that runs on top of ethernet (or other lower level protocols,
like Fddi, Token ring, etc. but let's not get into that). Hence it runs "beside" TCP/IP
on an Ethernet segment. It is different than TCP/IP, has its own numbering scheme,
usually uses different frame types (Ethernet_SNAP rather than Ethernet_II), and talks
to
its own higher level protocol such as Printer Access Protocol or Appletalk File Service
protocol, just like TCP/IP talks to its higher level protocol services like FTP, NFS,
etc.
Therefore:
When you bind Appletalk to your NIC in your Linux box, all you do is have that NIC
listen to Appletalk packets on that ethernet segment. In no way, shape or form does its
host "automatically" offer higher-level services like Appletalk File Service protocol
which would be needed for your MacOS workstation to see your Linux box as an Appleshare
server in the Chooser window. You would need an Appletalk Fileserver Protocol compliant
package to run on your linux box for this to do that. I think the shareware NetAtalk
does exactly that. On commercial Unix'es (SUN, HP DEC, SGI, etc.), a commercial package
called Helios EtherShare does it at blazing speed. It is however unavailable for Linux.
As for Constantine's advice to turn on file sharing: it has NOTHING to do with your
problem. What that would do is adverstise your MacOS workstation as an Appletalk
Fileserver Protocol compliant *server* on your network; but what good would that do,
since your linux box has no Appletalk Fileserver Protocol *client* running on it? The
only thing it would acheive is allow other MacOS workstations (which do have an
Appletalk Fileserver Protocol client running -- it's built into the MacOS and is called
AppleShare in the Chooser) to mount your MacOS workstations' shared folders on its hard
drive.
The quick and dirty way to quickly transfer files from your Mac to your Linux box is to
start an FTP server on your linux box and use an FTP client (like Fetch) on your MacOS
workstation, provided you configure your TCP/IP networking parameters properly in your
MacOS workstation's TCP/IP Control Panel.This way you avoid the Appletalk protocol
altogether. It is not elegant but will work. A more transparent and elegant solution
would force you to learn Appletalk networking and implement it as a fully functional
Linux service.
Hope this helps.

Just install IMAP from the RedHat CD and set up accounts for everyone on
the Linux box (they don't HAVE to be login accounts, but that might be
easiest).
To check mail, people just pop their mail (using Eudora, for example) from
the Linux box (using its IP address in place of a domain name). To send
mail within the group they just point their mail client (Eudora, etc) at
the Linux box.
I've done it, it will work, you may have to monkey with a few things, however.
The BEST thing about this is that you own the server and can play merry
hell with the aliases file. You can set up any number of mail groups and
you can have any number of mail aliases (for example, you can set yourself
up as "[EMAIL PROTECTED]"). Plenty of fun.

Certainly true. But...
...the linux VPN described in the HOWTO *does* provide that encryption
(ssh is the component that performs it).
>If that is what you wish to achive with a VPN then you are on the wrong track.
So, he shouldn't necessarily give up on this track. The tunneled
packets can be intercepted as you say. But once intercepted, there's
no way they can be meaningfully interpreted because they've been
scrambled beyond recovery.
