Two screens, two kbds, two users ?



  • 1. size of gnome applets?
    I'm looking at the memory usage of different gnome applet, and the size is simple incredible. For example, gweather-applet 10.7MB battstat-applet 3.9MB multiload-applet 6.4MB cdplayer_applet 5.5MB gconfd-2 8.2MB ... Some of them might be justifiable (e.g. CDplayer), but 10.7MB for the weather applet, and 6.4MB for multiload-applet??? I know they might share memory in some places, but still, this is ridiculously bloated. Is there any way to trim them down? They are nice little tools, but.... My system config: - RH9, Ximian desktop 2 with metacity thanks kk
  • 2. Minimal Linux Distribution with X and Netscape
    I'm looking for a minimal Linux distribution that will boot with X (1024X768 or 800X600) and run Netscape only. I'm trying to build an ultra simple web-client that can simply boot from CD-ROM (or a really small hard drive or flash-disk). Any suggestions? TIA, Zack (Email to zhamm at
  • 3. Xwindows without a Keyboard
    Hi I have a little proble here. I have a device with no real keyboard attached, so Xwindows will not start. I have to change the XF86Config file and set another inputdevice like that : Identifier "noinputdevice" Driver "void" In this case XWindows starts, but I lose the ability to simulate Keypress Events on the system. Does anyone has a solution for this ??? Thx Sebastian
  • 4. KDE and PATH
    hello, I am runnung KDE 3.1 on Debian testing/unstable and use KDM as display manager. I tried to add a directory to my PATH environment variable, with more or less success. Here's what I tried: 1. set it in /etc/profile -> no luck at all 2. set in /etc/bash.bashrd -> works partially. If I do a # env | grep PATH in Konsole the directory is part of the PATH, but: If I do "Execute Command" (ALT + F2) env > /tmp/test the directory is not part of the PATH I even tried further: 3. in the files - /etc/kde3/kdm/Xsession - /etc/kde3/debian/startkde I sourced /etc/profile Effect: now it works for regular users, but not for root... My Question: How do I adjust the PATH variable so that my adjustment works for both regular users and root? Inside an xterm-session and outside? Andy

Greetings.  Given a PC with two video outlets, is it possible to
plug two keyboards in (e.g. 2 usb keyboards) and associate each
keyboard with its particular screen in such a way that two users
can log in ?

We have a Userful station at the local library - four seats hosted from

Looks like you can download a 2-user version...
(Haven't done this yet)

Excellent link :-)  Also linked to from there:

The problem ("While the system worked very well, it was extremely
unstable. In particular, we got a kernel oops fairly often when we
logged out.") looks like it might be intractable, since they tried
fvwm and xdm as well as gnome.  Their approach (xorg.conf and
[gx]dm.conf) should port to *BSD too, so that might also be worth
a try...  I mean, just as an experiment, of course ...

It also raises the related off-topic question about logging in
multiuser at the getty level.  Getty, and AKAICS the tty driver
assume a bidirectional /dev/ttyXX device, so I'm also trying to
work out what pairs off kbds and screens into /dev/ttyXX devices.

Hoping to rediscover multiuser computing,   Regards,   Peter

2.Two distros, two video cards.

I am running Mandrake 10.1 with a modern GeForce video card (AGP).  I want
to install Mandrake 9.0 alongside it to run some old software that hasn't
been updated, but my new card isn't supported and I cannot start X, even
with the "nv" driver.  I don't seem to be able to get a usable set of
config options.

I still have my old PCI Riva TNT2 card, and would be happy to run it with
the "nv" driver for this purpose. If the NVidia driver works, that is a

Can I install both cards, and select only one in the setup on each distro? 
I think I saw something like that in the early days, when an old card could
be configured two ways, and showed up as 2 cards.  There is a thread on
getting two different cards to work at the same time, but here that
wouldn't be necessary.  Perhaps I can install the modern Xorg files on the
old distro, but that might introduce library version conflicts, which are
the reason for the whole exercise.  If it is possible, that might be the
next step.

3.One DHCP server - two interfaces - two subnets

        I run a DHCP server which supports wired internet in the internal LAN range Now I wish to add a wireless internet LAN in the internal
LAN range How do I accomplish this ?

/etc/dhcpd.conf :

option www-server,,;
ddns-update-style ad-hoc;

subnet netmask

subnet netmask

host clientwired
        hardware ethernet       wr:wr:wr:wr:wr:wr;
        fixed-address ;

host clientwireless
        hardware ethernet       wl:wl:wl:wl:wl:wl;
        fixed-address ;

where wr:wr:wr:wr:wr:wr and wl:wl:wl:wl:wl:wl are the obfuscated hardware
addresses for two clients - one wired and one wireless. How do I make sure
that the server listens on eth0 for the wired connections ( -
as it already does) and wlan0 for wireless connections ( ?



4.having two interfacesand two default routes..debian etch.

I've done a bit of research on this, but the answers are still unclear.

So any help appreciated.

I want to migrate a linux server fronm one ISP to another semalessly.

At some point, the dns servers pointing to it will switch IP addresses 
as caches time out etc, so for a while., I want it to respond via either 
ISP - I will have twin routers and twin DSL.

The only application of note is an apache web server.

The server is on 192.168 network using NAT routers

The server is on, and the current gateway is

Apache is not bound in any special sits on any and all interfaces.

Lets say I bring up another router to a different ISP on a different 
public IP address, and its Internal interface is


#ifconfig etho:1 will add a virtual interface to talk to it.

If I now add a second default route as

#route add default gw eth0:1

then it has a choice of default routes.

My question is this: will the network side of the kernel know which way 
to route packets originating from this machine in response to incoming 
requests down a specific interface?

I.e. with two default routes, will it pick one at random, or use the one 
associated with the interface that it received the packets on?

In particular Apache, as that is the only application that 'needs to know'

I.e. will apache always send packets out via the same interface as it's 
particular forked instance received them on? Or is it something deeper 
that makes that decision, in which case how would it 'know' which way 
the original source packet came from? It seems to me a state table 
-'route these IP address targets via that interface cos that's how they 
came' is needed?

I cant afford to let it go randomly via either  interface because each 
will translate to a different IP address as far as the world beyond NAT 
is concerned..

Anyone know chapter and verse?

5.How to set my Linux machine to have two network cards with two IPs

Dear all gurus out there,

I am newbie to Linux and networking.

I have a Red hat linux that used as a Database machine, oracle.

I have 2 network cards that I wish to set to and respectively, the default gw is The
connection of the two IPs coming from 2 different switches (still from
the same router).

My purpose is that : if one of the switches is down, my connection
still up with the other side.

I know switch is hardly "down", but i wish to have full redundancy.

What I did is, I jus set the 2 network cards with the two IPs and I
switch off one of the switches, "poof" the whole network, how can it be done ?

Or any other alternatives ?
