  • 1. iwlist scanning
    I'm using orinoco_cs driver from 2.6.6 kernel and when I try iwlist eth1 scanning I get Interface doesn't support scanning : Operation not supported error. I was under impression that scanning is a very basic functionality and that orinoco driver was supposed to support it. Without scanning, the driver is nearly useless. What am I missing ?
  • 2. pptpd - what is localip?
    In the pptpd config files, what is localip supposed to be? Isn't that just the address of the machine running the pptpd server? If this is the case, then why does the config file specify that you can have a range there?
  • 3. pptpd only works with a single client
    I have set up pptpd under Debian 3.0 and it works fine with a single client. The problem is, as soon as a second client connects, the 2nd client cannot ping anyone. I have updated my firewall script to forward packets from both ppp interfaces, but it still doesn't work. Has anyone got more than one simultaneous client to work with pptpd? cheers

Two network connections NICs not activating on Fedora 3 Linux 2.6.11-1.14_FC3

Hi,

   Running Fedora kernel 2.6.11-1.14_FC3

   This problem has been present since Fedora 2 (kernel 2.6 ?)

   I have a generic laptop with built-in UTP LAN socket and a Netgear
802.11b PCMCIA card.

   When the laptop boots, the onboard LAN is assigned eth0 and the
PCMCIA Netgear eth1 .

    Both appear as Active in the Network Device dialog - even if no UTP
cable is connected to the eth0 port .

   When UTP cable is plugged in, the eth0 can get DHCP IP Address from
the router and then connect out to the internet.

   However, when there is no UTP cable connected but there is wireless
card that shows steady green light, the device is not connected to the
router. I have to disable BOTH eth0 and eth1 then activate eth1 (the
wireless card) to get a DHCP IP address and then an active network
connection

   Is there anyway to get the NetGear wireless card on eth1 active and
usable after boot without going through all of this?

Thanks

Clive

1.two dsl connections, two routers, dual nics on linux box , want to run two websites 

Hello,

I have two dsl connections, with one public ip on each. I have a linux
box with two nic cards.

xx.xx.xx.xx(WAN)---ROUTER(LAN23.123.45.110) ---- MYLINUX
(23.123.45.107) eth1
yy.yy.yy.yy(WAN)---ROUTER(LAN192.182.1.1)   ---- MYLINUX
(192.168.1.100) eth0

I have apache listening on both interfaces. 

Problem:

1. How do I make the packets route back to the gateway from which they
originate.

Currently the gateway marked as "default" is able to serve content
from the apache. The other one cannot.

I tried adding static routes, but that didn't work.

Any help is appreciated.

Thanks
Jay

2.Mouse problems with " Fedora Core (2.6.11-1.14_FC3)" kernel 

Hi,

I have just installed a FC new kernel on my notebook, but it seems that
the mouse is less sensitive (you must hit strong the mouse). With the
previous kernel (2.6.10-1.770_FC3) the mouse run right. Has anybody
this problem ?

Thanks,
Jose Luis.

3.Two NICs, Two networks, secure websites 

Hi!

I have a Cisco router (provided by the ISP) that offers 29 usable IP's.
 One of the public IP's is set to be the WAN IP of a simple SOHO
Linksys router that then creates a private network 192.168.1.0.  There
is a Linux server with Apache on the private network.  Port forwarding
on the Linksys router allows SSL access to secure web pages,
unencrypted HTTP, SSH, etc. to the Linux server.  This all is working
OK.

I need to have a 2nd SSL site running on the same Linux server.  So, I
installed a 2nd NIC and connected it to the Cisco router and used one
of the available public IP's.  I cannot connect to the new public IP
(via the new NIC), but can still connect to everything described in the
1st paragraph above.

I can ping out each of the interfaces (e.g. ping -I eth0 yahoo.com  and
  ping -I eth1 yahoo.com both work).  The results of route are:

Kernel IP routing table

On the server, I can do   lynx https://192.168.1.2 and lynx
https://AAA.BBB.CCC.164.

>From outside of the server, https://AAA.BBB.CCC.163 works now, but
https://AAA.BBB.CCC.164 does not.  What needs to be done to allow
https://AAA.BBB.CCC.164 to work?  And/or, what can I do to troubleshoot
the problem?

4.Forwarding of multicast packets between two subnets with two NICS - Does not work 

WHY DO I NOT GET ANY REPLY FROM A DIFFERENT SUBNET? WHY ARENT
IGMP/MULTICAST PACKETS BEING FORWARDED THROUGH THE LINUX BOX?

Here is my setup:

                               Linux Box with two NICS
PC1         router          NIC(eth0)---NIC(eth1)          router
 PC2
192.168.1.100 192.168.1.1 192.168.1.111 192.168.4.114 192.168.4.1
192.168.4.100


Linux Box:
---------
/proc/sys/net/ipv4/ip_forward


PC1
----
ping 192.168.4.1 - works
ping 224.0.0.1 - only get reply from 192.168.1.1 and 192.168.1.111


PC2
----
ping 192.168.4.1 - works
ping 224.0.0.1 - only get reply from 192.168.4.1 and 192.168.1.114

5.Change inet on two NICs without loosing connections - Want IPMP solution 

Dear everyone,

	Academic question here:


There are three NICs on the same subnet on a Solaris 10 box.

ce0
ce1
ce2


The IP addresses for ce0 & ce1 are back-to-front.
	ce0 1.2.3.4
	ce1 1.2.3.5

However, these ought to be,
	ce0 1.2.3.5
	ce1 1.2.3.4

I want to swap these around on a system that cannot be shutdown and I do
not wish any established connections to be lost.

I exclude this solution of placing the ifconfig commands on one line and
pressing carriage return, which should be quick enough to work.

What I want is something sneaky using IPMP on the third interface of
ce2, which is also on the same subnet.

Anyclues?

Regards, z.
