jammcq, are you Jim Kronebusch?
01:44
<vagrantc>
lns: different jim
01:44
<lns>
ahh ok
01:44
<vagrantc>
unless jammcq has as many names as i do :)
01:45
<lns>
haha
01:45
keeps the mob off of ya
01:46
i think i'm going to write a HOWTO on vnc over an ssh tunnel to GDM for Ubuntu & LTSP - there's another really good HOWTO out there but they suggest to download xinetd...which...breaks LTSP :(
01:46
at least in a default install w/no config updating
01:46
<vagrantc>
vnc ... over ssh tunnel ... to GDM ... ?
01:47
<lns>
yep
01:47
<vagrantc>
that is... weird.
01:47
:)
01:47
<lns>
why is that weird??
01:47
lol
01:47
it's a great setup!
01:47
<vagrantc>
so vnc is running server-side ?
01:47
<lns>
Xvnc is (server)
01:48
with a single SSH port forwarded to public IP
01:48
so then you go to your client, start an SSH tunnel that forwards the regular VNC port (5901 for display :1)
01:48
to localhost
01:48
then you 'vncviewer localhost:1' and viola!
01:48
very fast, too
01:49
to a gdm login screen
01:49
which is nice if you have to reboot
01:49
<vagrantc>
sound and local devices work... ?
01:49
<lns>
nono
01:49
<vagrantc>
figured :)
01:49
<lns>
this is just for remote admin of the server
01:49
haha..i wish!
01:49
<vagrantc>
ah.
01:49
not for every client ?
01:49
<lns>
oh no
01:49
just the ltsp server
01:49
<vagrantc>
ok, that makes much more sense, then. :)
01:50
<lns>
;)
01:50
vino is nicely integrated but it's really lame for anything more than a home PC
01:50
with multiple admins wanting access, they need to have a login mgr..and ssh tunneling is just necessary for anything outside the lan
01:51
i guess its kind of a 'duh, of course' situation..but unfortunately there really isn't any good solid documentation on getting this going easily in linux
01:52
<vagrantc>
why not just use LDM ?
01:52
<lns>
not sure how to call it outside of ltsp...
01:52* vagrantc recently documented at least one way
01:52
<lns>
oh cool
01:53
<vagrantc>
it's an ugly way, though ...
01:53
<lns>
i guess it would be nice, but there's nothing really wrong with gdm either
01:53
<vagrantc>
if you're using ssh ...
01:53
<lns>
and if you have x running on the server (nice for lesser experienced linux admins, say, in a school) it defaults to gdm anyway
01:54
<vagrantc>
all you really need to do is ssh -X user@server /etc/X11/Xsession
01:54
<lns>
where's your doc?
01:54
oh totally, but i had some issues using XWinLogon earlier (had that implemented before this)
01:54
gnome kept bugging me about keyboard layouts for some reason afterwards
01:54
<vagrantc>
well, my doc is in the debian package, and in my bzr branch
01:54
<lns>
oh ok
01:55
<vagrantc>
it'll make it's way to ubuntu when they sync after gutsy release.
01:55
<lns>
vnc is just really nice too because even my Treo can run a client
01:55
cool

now wtf is this bullshit? http://developer.novell.com/wiki/index.php/LTSP_Gutsy_Gibbon
01:57
you click on one of those and it asks you for a un/pw
01:57
particularly meukow/ubuntu howto
01:59
<vagrantc>
lns: they are links that don't yet exist
01:59
<lns>
ahhh
01:59
ok
01:59
i'll take my tinfoil hat off
01:59
<vagrantc>
though seeing any docs for ubuntu on a novell site...
02:00
<lns>
seriously
02:01
first hit on google when you do a 'ltsp gutsy', too.
02:02

[sbalneav]:: the image that the client boot is what is under /opt/ltsp/i386 ?
07:54
<ogra>
cdealer, /opt/ltsp/images
07:55
<cdealer>
[ogra]:: and there are a way to use the image in a flash memory in the thinclient ?
07:55
<ogra>
no
07:56
you would need to change the initramfs to not try to do netbooting
07:56
i.e. change the ltsp-nbd script ...
07:56Blinny has joined #ltsp
07:56
<cdealer>
hmmm
07:57
[ogra]:: there are any voip program working in ltsp ?
07:58
<ogra>
no idea, as i said before we have b´no capturing by default yet
07:58
<cdealer>
yeah
08:02
[ogra]:: have you heard about the amd geode processors? We are studing the idea of buying thin clients with Geode GX2 466 and 128mb of ram, do you think its a good configuration?
08:03
<ogra>
i think so, yes
08:03
<cdealer>
the link to the thinclients http://www.brazilmkt.com.br/iclient/
08:03
<ogra>
i have some geodes here
08:04
<cdealer>
nice... you think im not lose perfomance then a celeron/sempron or pentium III ?
08:05
<joebaker>
Good Morning All ... I had a little excitement this morning.
08:05
<ogra>
sure you do, but thats not really relevant
08:05
<joebaker>
I added kqemu and VDE and Dnsmasq (for a virtual subnet).
08:05
<ogra>
the only thing where you casn notice preformance issues on a thin client is really the bootspeed
08:06
<joebaker>
And upon reboot this morning, dhcp3d failed to start.
08:06
<ogra>
since you told it so, what do you expect ?
08:06
<joebaker>
I need to specify in dhcp3d's config files that it should not try to bind to the virtual subnet.
08:06
<cdealer>
[ogra]:: are you saing that using this thinclients it could be more slow the boot ?
08:07
<ogra>
joebaker, if there is a dnsmasq server running dhcpd will respect that and not start
08:07
<joebaker>
dnsmasq is/was configured to only bind to the virtual subnet.
08:07
I actually hope to have them both operating.
08:07
<ogra>
cdealer, no, i say that if you notice perfocmance issues it will be the beeotspeed
08:07
*bootspeed
08:07
<joebaker>
Each on seperate interfaces.
08:08
<ogra>
joebaker, i'd realy go with one server for the task ...
08:08
<joebaker>
But maybe I can just use dhcpd3 to control them all.
08:08
Is dnsmasq up to the task of providing LTSP level dhcp support?
08:09
<cdealer>
[ogra]:: but when you say issues what you mean? I think issues could not be a good thing, right
08:09
<ogra>
no idea
08:09
<joebaker>
Well maybe I'll investigate it a bit and let you know what I find.
08:09
<ogra>
what i meant is bad client performance rarely affects the session
08:09
only the boot speed
08:11
<cdealer>
sure.... the only problem im seeing about this thinclients is that we will have to buy some usb cdroms and diskets so users who need them could use
08:13
<ogra>
i'D just give out usb keys ... 2Gig cost about 20€ over here, cant be more expensive than a CDrom even in .br :)
08:14
<cdealer>
[ogra]:: it isnt, but someuser may bring cds and diskets to the work.. and they will need to read them, so if we buy 2 or 3 usb cdrom drives we can workaround this problem.... and about the usb stickys most users already have it... the cdroms would be more for legacy use

08:15
<cdealer>
morning]
08:18
<joebaker>
dnsmasq is a DNS, DHCP and TFTP server...
08:21
<sbalneav>
ogra: heh, quite the exchange between you and hasan over debconf :)
08:22
<ogra>
yeah
08:22
well, he has two workarounds ... so i dont mind it for gutsy
08:22
eve though i'd still like to know why the intel driver doe it
08:22
*does
08:25
<joebaker>
Any release party plans?
08:26
I want to celebrate Gutsy when it goes live.
08:28
<sbalneav>
Ah, that reminds me. Need to send an email to my local Unix Users Group and see if anyone's interested in getting together for a brew for Gutsy.
08:29
Usually not: Winnipeg, for reasons that escape me, is a Fedora town.

I've got a few questions about the boot process. from power on of client to finish. Reason being I've come up with an idea about load balancing ltsp servers.
08:38
<mikkel>
Anyone know if it is possible to add a digital camera to the thin client and then access it from the server running X and not by USB storage but directly ?
08:40
<joebaker>
mikkel: I've heard of a driver somebody wrote for the Linux kernel which attaches remote USB systems back to the server over TCP/IP.
08:40
<mikkel>
joebaker, Cool, that sound like what I need.
08:40
<joebaker>
I havn't heard of anybody using it within LTSP.
08:41
Keep googleing Good Luck!
08:41
<mikkel>
joebaker, okay thanks.
08:41
<sbalneav>
mikkel: You're talking a gphoto camera?
08:41
<jammcq>
Scotty !!!!!!!!!!!!!!!!!!!!!!!!
08:42
<sbalneav>
Morning jammcq!
08:42
<mikkel>
sbalneav, Yes
08:42
<tsurc>
If I load balance tftp does anyone think that I can evenly distribute clients between servers and still be able to use LDA/Souns etc
08:42
<sbalneav>
mikkel: We've got a spec on that. What we need to get going is gphotofs
08:42
<tsurc>
*Sound
08:42
<sbalneav>
tsurc: Gutsy has load balancing capabilities built in now :)
08:43
<joebaker>
What's LDA?
08:43
<tsurc>
;) oh goody
08:43
<sbalneav>
Local Device Access
08:43
<joebaker>
Oooooo
08:43
<mikkel>
sbalneav, will look at that. Thanks.
08:43
<sbalneav>
jammcq: I need to book some flights today.
08:43
<tsurc>
you guys are the b........ best :)
08:44
sbalneav: any docs on it?
08:44
<sbalneav>
jammcq: on the flight home, I should book something from DTW to winnipeg on Wednesday?
08:44
tsurc: Yup
08:44
!handbook
08:44
<ltspbot>
sbalneav: "handbook" is The edubuntu handbook is the best source of LTSP5 documentation. You can find it at: http://doc.ubuntu.com/edubuntu/handbook/C/
08:45
<joebaker>
In the scientific community there is this bus called GPIB General Purpose Interface Bus. Oscilliscopes, programmable power supplies use it.
08:45
<tsurc>
ah ha, thanks.
08:45
<sbalneav>
The Gutsy version of the handbook that comes installed on Gutsy has all the docs on the loadbalancing features.
08:45
<joebaker>
It's slow ... max of 1.5 megabits per second.
08:46
Anyway they developed this over Ethernet way to access devices like GPIB, Serial Ports,
08:46
<sbalneav>
joebaker: heh, used to have to use it back when I was at the University.
08:46
<joebaker>
parallel ports etc. Called VISA.
08:46
<jammcq>
sbalneav: yeah, wednesday, DTW->YWG. Hopefully not too early in the day
08:46
<sbalneav>
ok, I'll work on that today.
08:47
<jammcq>
sbalneav: when are you flying out to BOS ?
08:47
<joebaker>
We use allot of GPIB here where I work. Programs measure crystal oscillators that we build.
08:48
<Blinny>
Will lengthy boots be sorted by Gutsy?
08:48
<tsurc>
currently 57% through a download of edubuntu-7.10-beta-server-i386.iso. the daily wouldn't work for me. Cupsys would install.
08:48
<joebaker>
We can pick this discussion up next month. Thanks for the LDA news!
08:49
We've had mixed results with the Edubuntu-7.10-beta-desktop-i386.
08:49
One user boots up to a desktop and can launch firefox, but cannot start the installer.
08:49
Or maybe he launched it twice.
08:49
<sbalneav>
jammcq: Either Friday night, or early saturday
08:50
<ogra>
sbalneav, i'll arrive sat. afternoon
08:50
<sbalneav>
Blinny: We've improved boot times quite a bit.
08:50
<ogra>
13:45 or so
08:50
<sbalneav>
ogra: Ah, ok.
08:50
ogra: ARe you and I rooming?
08:51
<ogra>
no idea
08:51
just got my itenary which took me nearly four weeks this time (our travel agent sucks)
08:51
<jammcq>
sbalneav: you thinking about being there for FossCamp ?
08:52
<sbalneav>
When's that?
08:52
<jammcq>
sat/sun
08:52
<ogra>
jammcq, he has to
08:52
<jammcq>
I figured you guys would be all over that
08:52
<ogra>
jammcq, thats where we are supposed to do upstream/ubuntu stuff
08:52
<jammcq>
I'm even considering flying to boston for that
08:52
<ogra>
i.e. the *handover* of upstream :)
08:52
<jammcq>
ogra: yeah, how come you are missing half of it?
08:53
<ogra>
ask the travel agent :P
08:53
i'm happy i got a flight at all
08:53
<jammcq>
but that's their JOB, for crying out loud
08:54
<ogra>
(for the cyprus flight last week *i* had to send him the best flights, he was not capable finding something that wouldnt have meen at least half my mothly loan)
08:54
s/meen/been
08:55
(i culd have chartered a flight for his fees)
08:55
sbalneav, but since you expressed iterest and claire knows my general "i dont care" i guess we'll share
08:56
<cdealer>
i think we are having problems with packets lost using ltsp... the
08:57
where do i see the clients ips (info) ?
08:57
<ogra>
on the login screen (bottom right)
08:58
<cdealer>
in the server isnt a way ?
08:58
<ogra>
(unless sbalneav patched that out and i didnt notice)
08:59
cdealer, just do a ping sweep on the TC network
09:02
<sbalneav>
ogra: Ohhh, BTW, I forgot, we've got a bug on the login screen.
09:02
<ogra>
do we ?
09:02
<sbalneav>
The time/date is in UTC, not Localtime
09:02
<ogra>
meh
09:02
<sbalneav>
I can look at that today.
09:02
<ogra>
well, my next upload will be the last one
09:03
<sbalneav>
when's that?
09:03
<ogra>
today
09:03
as soon as i have dropped the progressbar from the installer :P
09:03
rc freeze is today ...
09:04
i'm currentl mucking around in the artwork package ... then ltsp is up
09:05
<Blinny>
sbalneav: Awesome.
09:10
<ogra>
sbalneav, btw, how would you solve that ?
09:11
you cant determine if the HW clock is local or UTC
09:11
what you could do (and what i actually had planned but missed) is to send timestamp with the ldminfo data
09:12
and adjust the screen clock accordingly

Will Boston be your first touchdown on US soil?
09:57
Because if so, even though I'm arriving 15 minutes later than you' I'll probably beat you because I won't have to go through i18n customs.

Im with one slackware linux 12.0 running a LTSP 4.1 iso , by the moment I boot the terminals some of then load completely other cant mount NFS
10:28
some ideia about what could be ?
10:30Clown-MG- is now known as Clown-MG
10:35
<sbalneav>
Well, nfs is running, yes?
10:35
Are these ones that won't load nfs on a different subnet?
10:35

yay
10:35
its ugly but it works :)
10:35* ogra hugs the debian installer parts

i'm working in a vm yet
10:36

now i just need to figure out the NIC stuff ....
10:37
i still cant belive i ever noticed that bug
10:38
<sbalneav>
ogra: for the clock thing, can't we use the timezone information in the chroot to adjust the clock?
10:38
Or don't we have TZ info in the chroot?
10:38
<ogra>
not for the HW clock
10:39
you have a TZ but you dont know what the user has set in his BIOS
10:39
if there was a windows installed before it will be localtime
10:39
<sbalneav>
How's a HW clock on a thin client any different from a HW clock on a server?
10:39
<ogra>
on unix or barbones systems that never had an os it might be UTC
10:39
not at all
10:39
<sbalneav>
Ah, I always set my systems to localtime
10:39
is that bad?
10:40
<ogra>
its the same, thats why we still ask in the installer if the HW clock is UTC or not
10:40
<sbalneav>
Ahhhhh
10:40
but we don't do that for the ltsp-build-client.
10:40
<ogra>
the prob is that you cant just apply that to the client
10:40
since you dont know the BIOS values yet
10:41
i would leave the system clock alone and just adjust the displayed one on the screen
10:41
if you want to set the system clock we need to do that from initramfs already i fear ... else you get timestamp issues etc during the boot

sbalneav, sorry
11:01
sbalneav, they are in the same subnet all working with the same server, the most strange thing.. is while I have 2 terminals working i can run showmount localhost -e
11:02
after other machine it just dont awnser nothing freezy
11:06
<sbalneav>
hm
11:06
Switch or hub connecting them ?
11:07
<kernelfreak>
switch
11:07
I was thinking about the terminals are working on 100mbit on the server I have a 1gbit card
11:07
<sbalneav>
Smart switch? Any chance the switch is blocking UDP or something like that?

sbalneav, no beacaus I have an old Suse working as a server..
11:10
<sbalneav>
How many terminals are we talking? Maybe you need to increase the number of NFS threads?
11:11
Any messages on the terminals that don't boot?
11:11
<kernelfreak>
sbalneav, 15
11:11
sbalneav, no messages it only stay long time trying to mount.
11:11
and nothing happends
11:11
<sbalneav>
What kind of switch is it?
11:12
<kernelfreak>
is 3com with gigabit uplink port
11:13
<sbalneav>
Have you tried just plugging the server into a regular port, as opposed to the gigabit port?
11:14
<kernelfreak>
sbalneav, Ive read the troubleshooting got some possibility like kernel 2.6 blocks
11:14
sbalneav, not yet
11:15
sbalneav, I will try by the end of the day recompile the serverkernel on 2.4 series.
11:18
sbalneav, I just dont understand why can 3 machines and when anyother tries nobody else can trie the server just dont awnser
11:19
<sbalneav>
I'd also check your /etc/hosts.allow, and /etc/hosts.deny
11:19
<kernelfreak>
just to easy my mind I clear the denny and ALL:ALL in the allow

kernelfreak: you need something in that host.allow. ALL:ALL probably covers at least three important options I can't think of right now.
11:44
NFS, TFTP and ... well maybe sshd.
11:45
<kernelfreak>
joebaker, the main problem are in NFS
11:45
joebaker, because it bootup and loads the kernel in the right way.
11:45
<joebaker>
Did you try putting server on 100 Mbps
11:45
<kernelfreak>
joebaker, I thougt about it today
11:45
will try it latter
11:45
<joebaker>
UDP packets could get deliverd out of order.
11:46
Switches have buffers.
11:46
You might even have multiple switches between the server and the clients.
11:47
I usually setup a ping to the IP of the server that keeps going when moving the ethernet.
11:47
To force the discovery of the new port as soon as possible.
11:47
It will probably take 20 seconds for the switch to redirect.
11:47
<kernelfreak>
joebaker, I will check it at the old sevrer because I have one old one working perfectly ..
11:48
<joebaker>
I can't say this is the problem. But I've seen enough to suspect it.
11:48
<kernelfreak>
joebaker, it makes sense
11:49
<joebaker>
The other weird thing I see sometimes are boxes with multiple NICS.
11:49
thin clients with multiple nics.
11:50
<kernelfreak>
joebaker, isnt the case.

joebaker, other think that i noticed.. is that while 2 machines are working well i can do a showmount at the server and see everything ok.. after one machine dont work the command just dont work
11:52
<joebaker>
Hmmm... I wonder if the DHCP server could be giving it's own IP address out to a client.
11:52
restarting portmap might help.
11:52
Or re-runing exportfs -a
11:53
<kernelfreak>
after restaring the portmap it works but I dont think there is other machine with the same IP
11:53
<joebaker>
Is the server assigned a static IP address?
11:53
<kernelfreak>
joebaker, yes
11:53
<joebaker>
DNS is the server reverse name served by your DNS server?
11:54
IE if you lookup the server's ip address on the network does the name come back?
11:54
<kernelfreak>
no..
11:54
<joebaker>
Is there any chance another machine is registering your server's hostname into the dns server?
11:55
<kernelfreak>
no
11:57
<lns>
kernelfreak, not sure if this has been asked but are all of your thinclients the same hardware?

12:03

And does anything show up in the local X server log when you try?

other question ... when I plug a pendrive or a cdrom at the server it open to all clients... how can I avoid this to happen

cdealer, you can't plug it in directly to the client?
14:09
<cdealer>
[joebob777as7_]:: sure but the problem is when I have to plug something on the server to make some config or i dont know what ...but it must not open to the clietns
14:11
<joebob777as7_>
oh ok i get it. i think if you make it so the users can not access external storage devices automatically in system administration users user privileges...?
14:13
<cdealer>
something like that... imagine the situation, i have to install something in the server, so i pic up the app cdrom os pendrive and plug in the server.. and them that driver open in 60 clients ... they are all users so they will be scared and start calling to the support
14:13
hahaha
14:18
<joebob777as7_>
do you know cdealer when i have to update client images? do i need to when i update the client or when i update the server?
14:19
<cdealer>
the images are on the server.... so if you update on the server the pxe clients will take the new image
14:28
<joebob777as7_>
yes but when do i need if ever to update those images?

Hey, can anyone verify where you set the monitor stand-by mode for LTSP clients? is it /opt/ltsp/i386/etc/inittab or handled somewhere else?
14:42
<sbalneav>
cdealer: No, audio isn't supported
14:54
<lns>
would it be ideal to turn off screen blanking/DPMS under /opt/ltsp/i386/etc/X11/Xsession.d/myscripttorun, by using 'xset s off' and 'xset -dpms' ?
14:56
doesn't seem like there's a static xorg.conf file to disable dpms or anything... does xorg create a dynamic xorg.conf file per station when booting via hardware detection?
14:57cdealer has left #ltsp
15:01Blinny has quit IRC

15:04
Why not just do it on the server, as part of /etc/X11/Xsession.d/something
15:05
<lns>
sbalneav, ok, wasn't sure at that point where the client was pulling config info for Xsessions - would that be a better place than in /opt/ltsp?
15:07
<sbalneav>
Sure. The xset can happen either on the server or the client, and if it's on the server, then you're not having to maintain customizations in the chroot you have to remember to maintain later.

i'll assume you guys are good with NFS mounts and might be able to help me
18:42
i'm running into a problem where clients mount a root and secondary filesystem via NFS, then aren't able to quickly open files. the client reports the first reqest to the server was unresponsive and a second is performed, which goes through
18:43
i'm unsure what causes this behavior, but it's quite annoying
18:43
machines i have with root hard disks and secondary (nfs) mounts don't exhibit this problem

Hi All, First time IRC user. Recently setup a Edubuntu server and several clients. So far it has gone pretty well. However, the non-Linux computers in the house cannot get out to the Internet through the Edubuntu DHCP server.
23:06Amaranth has quit IRC
23:08
<JayPerez1>
I can see that people are coming into and leaving the room but don't see any chat at all. Can anyone see this ???
23:10
<sbalneav>
JayPerez1: Yep
23:10
It's just that no one's talking right now.
23:10
<JayPerez1>
Thank you. Wasn't sure if I did it right.
23:17
<booghotfoot>
JayPerezl--did you configure the gateway properly?
23:20muh2000 has joined #ltsp
23:20
<JayPerez1>
I didn't have to configure anything to get this far and don' t know how to correctly set up the gateway info. Are you referring to the server or on the non-linux computers ?
23:21
<booghotfoot>
the server. Does your machine have two nics or just one?
23:22
let me rephrase my response after having read your question more closely
23:22
<JayPerez1>
Two. They seemed to work out-of-the-box for everything else. All my computers in the house cans see both the Edubuntu and the other network.
23:23
The Edubuntu server and clients can get to the Internet.
23:23
<booghotfoot>
are there winsows boxes that cannot get out
23:23
<JayPerez1>
Yes. That's the problem.
23:23
<booghotfoot>
are they on the same network and subnet?
23:23
<JayPerez1>
Yes.
23:24
<booghotfoot>
what is the gateway device for the ubuntu server, and is it the same gateway for the windows boxes?
23:25
<JayPerez1>
Everything in the house is connected to a 16 port switch which is connected to the second NIC on the server. The 1st NIC is connected to my cable modem.
23:26
<booghotfoot>
so you do not have a router on your network? Ubuntu is acting as the router for the thin clients?
23:26Amaranth has joined #ltsp
23:26
<JayPerez1>
I had/have a wireless router but I took that out of the system for now so the Edubuntu server is the only device serving DHCP.
23:27
<booghotfoot>
and your windows boxes are getting address and gateway info from the ubuntu server?
23:28
<JayPerez1>
Yes, I think so. They seem to be successfully be getting an IP address from the server.
23:28
<booghotfoot>
if you type ipconfig /all at a command prompt in windows, you can confirm what the windows box is getting
23:29
<JayPerez1>
I don't really understand the 'gateway' stuff so it may not be configured correctly.
23:31
I don't have a windows machine in the room where I'm sitting right now. Will I need one to continue this chat ?
23:31
<booghotfoot>
can you check it conveniently, I will be hanging around for a while?
23:32
I'll find a quick resource for you to look at explaining gateway concepts.
23:32
<JayPerez1>
I know it's getting an IP address OK. What other info do you need me to check ?
23:32
<booghotfoot>
the gateway address
23:33
<JayPerez1>
OK
23:33
<booghotfoot>
we need to make sure your dhcp server is handing out the proper gateway address
23:39
the second nic on your ubuntu box is the gateway for all computers on your network except the ubuntu server.
23:40
all of the thin clients and the windows boxes need to point to this nic's address as their gateway. it probably has a 192.168.x.x address
23:42
that nic then uses the nic connected to your cable modem as its gateway. This setup isolates all of your computers except the server from the internet
23:42
<JayPerez1>
Sorry for the delay. None of my other boxes are boot up right now except one that is having some issues. Will go check another downstairs.
23:42
<booghotfoot>
no problem
23:43
so, when the windows box wants to get a web page, the request goes to the inside nic on the server, and it passes it to the nic connected to the modem.
23:44
When the server gets a response back, it hands it off to the inside nic to send back to the windows box.
23:45
So, in effect, the windows box is not connected directly to the internet. It has to talk through the gateway
23:47
<JayPerez1>
Thanks. I have tried configuring my windows PCs with that info in an earlier attempt to get this to work but was not successful but may have been doing it wrong.
23:48
<booghotfoot>
can you ping a windows box from your server?
23:48
<JayPerez1>
My PCs IP is 192.168.0.250, Gateway is 192.168.0.1, Subnet Mask is 255.255.255.0, DNS Servers is192.168.0.1
23:49
<booghotfoot>
that looks good. can you ping 19.168.0.1 from the pc?
23:49
192.168.0.1 sorry
23:49
<JayPerez1>
Everything inside the house works and all my boxes can communicate and share files with SAMBA
23:49
<booghotfoot>
okay, but they cannot get out to web, is that right?
23:50
<JayPerez1>
Right, the windows boxes can't. The server and clients can.
23:50
<booghotfoot>
just a second...
23:50
<savetheWorld>
Winboxes need know what IP is gateway.
23:52
<JayPerez1>
ipconfig /all is reporting the gateway correctly, I think.
23:53
<booghotfoot>
do you have ipforwarding enabled on the ubuntu server?
23:54
<JayPerez1>
On Edubuntu server, ifconfig doesn't use the term 'gateway' in results ...
23:55
If ipforwarding is on it's because it came that way off the CD. I don't know how to configure that.
23:56
<booghotfoot>
just another minute
23:56
<JayPerez1>
Thanks booghotfoot
23:58
I prefer a solution that doesn't require me to configure the winboxes if possible as I am constantly adding/changing computers and have people come over with their laptops to connect to my network.
23:59
<booghotfoot>
your winboxes are just fine. no changes needed there
23:59
you just need to enable ipforwarding on the ubuntu box
