Subject: Poor man's failover?
Date: Thu, 18 Feb 1999 11:29:19 GMT
I run a small hodge-podge of computers loosely referred to
as a 'network.' We've got two servers, one in a dorm running
the local LAN, the other across campus (on a T1-connected
backbone) running our Internet services (web hosting, email).
The two are connected with a pair of 33.6 modems.
We're getting an xDSL line run into the dorm, and we're going
to at the very least move the cross-campus server into the
dorm. Since we'll have two relatively comparable machines,
and reliability and up-time are going to be imperative, what
I'm thinking of doing is this:
+-------------------------------+ +-------------------------------+
| EBHON SERVER | | SPRAWL SERVER |
| eth0 eth1 | | eth1 eth0 |
+-------------------------------+ +-------------------------------+
# # # #
# ################ #
# #
# ##############################################################
# #
# # +----------------+
# # ##################| xDSL interface |
# # # +----------------+
+--------------+
| HUB |
+--------------|
We're using a firewall, so all our local IP addresses are
'generic' Class-C (192.168.x.x). The configuration would
be something like this:
EBHON SPRAWL
eth0 192.168.0.1 not assigned
eth1 192.168.1.1 192.168.1.2
Once a week or so, SPRAWL uses eth1 to mount whatever variable
directories are on EBHON (nfs) and does a backup to the
corresponding directories on its local filestructure. (EBHON
also has a tape drive.)
Additionally, SPRAWL would periodically ping EBHON using eth1.
If for whatever reason it got no response, it would bring up
its own eth0 as 192.168.0.1 and thereby pick up the network
traffic destined for the primary server.
I think I can do all of this with some fancy shell scripts
and creative use of cron. It's cheap, and it just might work.
But before I lose sleep and hair, is this a workable solution?
I know the hardware duplication is a bit extreme, but we've
had bad karma with hardware, and we've definitely got more
than a surplus of hardware...
Thanks all!

i had ppp working with 2.0.34 and 2.0.36 and i could not dial out at all
after i went to 2.2.1 (slackware 3.5 and ppp-2.3.5, net-tools 1.50). after
a few minutes experimentation i discovered that if i removed the '\r' from
in front of the first AT command (in ppp-on-dialer) that is sent to the
modem then things started to work again. the AT command may not be needed
at all but i left it in anyway. perhaps something changed in chat.

Hi all,
I would like to setup a a home network consisting of an NT server, a
Windoze 98 box and a Linux box running RH5.1. I want to use the Linux
box as a caching proxy for the rest of the network with a demand dial
connection to my ISP.
Do I need to use NAT (IP masquerading in Linux) or will Squid be
sufficient? I heard that Squid can, if configured correctly, act as a
firewall of sorts. Has anyone used Squid in this way? BTW, where can I
find an RPM for a stable release of Squid? I saw a site recently that
had release 2.1PATCH2 (I think) but forgot to note it.

At our office, we use volcano names.
The network started with only 3~4 machines, so it was easy to dig out
our
brains to find Etna, Pinatubo, Vesuve and a few famous ones.
But when it has grown to ~20+ machines, we had to look at a world atlas
to
find new names.
Now, the network has ~200 machines and we found a database which
references
3000+ volcanoes on Earth (yes, there are so much !), so we are okay for
a
while !

Date: Thu, 18 Feb 1999 10:21:18 -0500
Hello,
after reading the
Mini-HowTo on using multiple Ethernet adapters with Linux at
http://cesdis.gsfc.nasa.gov/linux/misc/multicard.html
with RH5.2 (actually mandrake 5.3 using dhcpcd-.70-2 )
I concluded I should set my /etc/conf.modules to:
alias eth0 3c59xx
alias eth1 ec09xx
the computer boots but DHCP fails to initialize.
when conf.modules is set to only the first line, DHCP initializes fine
(or you wouldn't be reading
this).
Has anyone got a similiar set up working? better/clear references?
After I get the two cards going, I'm going to set up samba as a file
server for an NT box,
but one step at a time.
thanks,
ira

Subject: a small problem with ip-masqurading configuration.
Date: Thu, 18 Feb 1999 15:12:57 GMT
Hi, I'm from Chandigarh, India. I have setup a small network with a server
and five client machines. I'm using RedHat 5.2 (2.0.36) to configure
ip-masqurading on my network. The hardware includes six Compex RL 2000
ethernet cards which work perfectly fine with the NE2000 (PCI) driver shipped
with RedHat 5.2, a US-Robotics 56k modem and 6 assembled computers. The
problem I'm facing is that my internet connection works fine if I override
the configuration of LAN during the installation of RedHat, but if i
configure my LAN during installation then after that I am not able to connect
to my ISP. The exact problem that i face is that after all the handshaking
and all has occured (i've got a normal dial-up TCP/IP connection) the browser
i.e is netscape keeps on showing "looking up host ........." and nothing
happens after that. Please suggest some solution to this as this is becoming
really irritating. If you think that the detail i'm sending is less then also
just please let me know about that. Thanks and regards, VASU.

Here's some observations, but without much hope they will help.
The <CONNECT ''> sends an extra carriage return that sometimes causes the
ISP to become confused. <CONNECT '\c'> avoids this, but you use the

The ISP seems to be asking for Multilink PPP, at least I *think* that
the unnamed options below refer to. Pppd can't do this and rejects them.

The ppp-2.3.5 pppd was compiled under 2.0.36, I don't see why it shouldn't

I do know that there is new 2.2.1 kernel support for PPP relative to

Hi gurus.
Sorry if my questions seem dumb.
We're planning to setup network at our site.
Let me describe first what we're planning to do:
Host1 Host2 Host3
| | |
-------------------------- Gateway------- To ISP
| (Linux with
File Server 2 NICs)
Hosts and FileServer are equiped with 100BaseTX cards.
The Gateway is 486 box with Linux and two 10BaseT cards.
Let me make this point clear: there's no way to insert
there 100BaseTX card, since all available 100mbps ethernet
devices are PCI cards, while our 486 is ISA and VLB only.
The question is: what will happen when a workstation
(say Host1) starts session with Gateway? Would the
interface at Host1 drop to 10 mbps? If yes, what will
happen if Host1 starts session with FileServer at the
same time? Would FileServer also drop to 10 mbps? And
if the answer is yes, would any host on the LAN talking
to FileServer become 10mbps? (Let's call this scenario
"10mbps propagation").
If "10mbps propagatrion" really takes place, does there any
solution (like "wise hub") exist?
Thanks a lot.

Peter,
Actually, there is one ISA card out there that claims to be
100TX. It's the 3COM 3C515. I don't know if there are
drivers for it under LInux though, and it really only gets
about 25Megabits per second due to limitations of the ISA bus.
More importantly, how are you planning to connect this network?
If you use a regular 10Mbs hub, all the systems on this LAN will
be running at 10Mb/s. Another alternative is a 10/100 switching
hub. Using such a hub, Host 1 can talk to the file server
at 100Mb/s. Host1 would talk to the gateway at 10Mb/s though.
The 10/100 dual speed hubs have switching circuitry that does
this internal to the hub.
Does this answer your question?

Hi,
<p> We have an NT network in the lab, and I set up a Linux
server (independently) on the same network. The Linux box has its own IP
address and qualified domain name, and does not interfere with the NT network
in any way. The NT server is a print server for a HP 4000N Network printer.
Since the printer has its own IP address, I was trying to figure out a
way to make the Linux box be able to print to this printer with or without
(preferably) considering something like SAMBA. I was not able to find anything
pertaining to this case in the HOWTOs, and I am hoping someone would be
able to help me out and give me a head start on making this work.
<p> Someone please hear me! Thanks!

Try 'man sendmail'. Look for the '-q' option.

I am trying to collect mail for root on the linux box and read it with
NS running on an NT box.
I keep getting the message that the login is wrong.
Is there a way to enable root login for mail (pop3) only? Or, can I set
up mail forwarding for root that forwards to normaluser@linuxbox?
TIA,
Yan
