Weird. Very weird. My ISP (Sympatico) doesn't support Linux usage,
but now that they've moved to PPPoE, it isn't the nice simple DHCP
anymore. Ugh. Now I gotta deal with this stuff:

Any idea why, upon receiving my correct username and password, it
dumps me? I'm calling them about it in the morning, but I was hoping
maybe someone's run into the same problem, cos I'd rather get it from
a group that's Linux-oriented and can help with ADSL than from a tech
support group that's ADSL-oriented and will likely feed me the line
that, although they gave me the software, they don't support Linux.
Ugh.
(And please, don't tell me to switch ISPs. I'm already considering
it, and will (will have to, that is) if this doesn't work out.)

i think this is a memory overcommitment (due to lazy page allocation)
problem. add more swap space and see if it helps.

I have a 486 SX -25 mhz machine. with a 40mb HDD and a monochrome video
card (Hercules - Text only, pretty much)
Would it be possible, to somehow get a version of something, probably
linux on to it, so it can just sit there and work as a firewall or
tcpwrapper or whatever the hell you need to act as protection to your
system? The burning question is, will it be possible.. I can put a 300mb
HDD on it, but I would prefer to keep that one else where..

Assuming that you have compiled your kernel with
CONFIG_IP_ALIAS=y, you need to use eth0:#, where # is the number of
the
aliased interface: i.e. eth0:2.
Give that a try.
BL.
--- end of quote ---
i tried:
ifconfig eth0:1 198.115.160.6 netmask 255.255.255.0
i got back:
SIOCSIFADDR: Invalid argument
eth0:1: unknown interface.
SIOCSIFNETMASK: Operation not supported by device
Still wondering how to tell if the currently running kernel supports IP
aliasing. I snooped around /usr/src/linux/net and found this from the
most recent build:
# grep ALIAS *
Config.in:bool 'Network aliasing' CONFIG_NET_ALIAS
so does this seem like everything was built with IP alias support or
some way to check directly?

Hi Rob,
I use the @home cable network and this is what I had to do to get
it to work
1. take pump off the machine, rpm -e pump
2. install dhcpcd off the redhat cd
3. change /etc/sysconfig/network to look like this
NETWORKING=yes
FORWARD_IPV4=true
HOSTNAME=ci123456-a.athen1.ga.home.com
DOMAINNAME=athen1.ga.home.com
GATEWAY=24.9.213.1
GATEWAYDEV=eth0
(use your domainname and hostname from @home )
add dhcpcd -h ci123456-a to the bottom of /etc/rc.d/rc.local
script
(use your hostname)
at the command prompt type
dhcpcd -h ci123456-a to fire up dhcpcd and you should get back a
ip-number
the next time you reboot rc.local will take care of getting a ip
from @home

Edit /etc/hosts file and add your win95 and nt machine ip address, I guess,

And I think that ftp response is also slow, this problem can be solved by like
below
160.152.17.102 win95ip
160.152.17.103 nt40ip
But I have no idea what cause this problem.

Subject: The performance of IP chains
Date: Mon, 13 Sep 1999 05:01:54 GMT
I set up a Linux router and the performance is really bad. On my linux
machine I can download a certain file off of www.microsoft.com at 120k
a second. (downloading a big file off of microsoft is a GREAT way to
test the performance of your bandwidth by the way. Their servers are
FAST). Anyway, if I do it through one of the other client machines on
teh network, i only get about 27k a second. Interestingly, if I have
three machines on the network downloading the same file at the same
time, they ALL end up at 27k a second. You would think it would slow
down somewhat.
Is slowness just inherent in IP forwarding with the Linux kernel? Just
curious. . .

Hi, I've added those lines to my lilo.conf and modules.conf but my two 3Com Etherlink
III cards
still don't work.
They are both recognized at boot up and the following message prints:
eth0: 3c509 at 0x380 tag 1, 10baseT port, address <snip>, IRQ 11.
3c509.c <snip>
eth1: 3c509 at 0x300 tag 2, 10baseT port, address <snip>, IRQ 10.
...
but if after logging in I run ifconfig it only shows eth0.
My question is this: even if the second card is recognized, how do I get all the files
needed to use
it installed? The files I'm talking about are things like /sys/net/ipv4/conf/eth0 and
what ever
else it takes. If that sounds like a stupid question it's because I'm used to Windows
where you add
a device and get a whole bunch of files created/moved for you.

I just installed Red Hat linux 6.0 on my system. I can telnet into my

get ANY response if I do it through the net (say, from work). Not even
a login prompt. And I know telnet is working because I can do it
locally.
Interestingly, my FTP server is responding to requests on the net. Do
cable modems somehow prevent telnet access or something? I checked my

Any suggestions?

Thanks all for the replies!
OK, so fetchmail can do what I need it to do. But, how? If I run
fetchmail as root, won't the permissions get all messed up (the
mailbox permissions)? And, on our system, each user only has access
to his/her home directory (i.e., /home/user permissions are 700), so
one user running fetchmail for all the others may not be possible.
Finally, our Linux server is character-based only, so I can't run
fetchmailconf.
Thanks again for any information.

Thankyou for your response.
I have checked the route print in window98
Here is what it printed:

I have also checked the Linux side it is ok.
>From above, I do not know where the 224.0.0.0 entry coming from. There is
nothing in my network setup. I have tried to delete 224.0.0.0 but it
says the network does not exit.
The rest seems to be ok. In particular the local lan which is
192.168.1.0 is route through 192.168.1.11 which the window network ip.
192.168.1.10 is a linux ppp gateway to the internet. I have terminated
the ppp connection, then
the local lan is down as well, from the window guest os perspective. I
can still ping the other machine on the Lan.
It is just that the neigbourhood does not recognise the network
connection anymore.
After I took the ppp down I have checked the route table of window os.
It did not change. I rebooted window
again the route table is still the same. It seems the route table is ok
except the 224.0.0.0 bit.
Do you see any problem from the above. Mind you this is what happen when
the
internet is up and the local lan is working.
