Hello, all, getting ready to go to the NAMES show.
Does anybody know why an Ubuntu system absolutely crawls if it is not connected to the network? I don't expect to have network access at NAMES.
it crawls always, or only during boot?
ISTR booting without a network takes a long time because it looks for the net
I've never noticed problems just running without the net, but I don't do that often
No, boot seems ok, logging into KDE takes about 5 minutes, and getting the term emulator to complete the screen takes maybe 3 minutes.
you're not running stock ubuntu...
Whatever the windows manager is.
oh, you are running stock? (stock is gnome)
OK, right, it is Gnome.
did you try disabling the ethernet connection?
how fast is the pc?
It is a 600 MHz Pentium (3?) with 256 MB memory. It is totally adequate for EMC compiles.
yeah, thats not it (just checking)
I did not try disabling the ethernet, then I'll have to get the networking all back when I return.
when you are on the net, how is it set up? dhcp, getting a lease from your local router? or manually configured?
No SHCP, manually configured, and with some screwy network config that I use here.
it's probably looking for dns
unless you somehow tell it there is no net, its gonna keep trying I bet
MMM, good thinking, DNS!
with DHCP, you get a long lag at boot as it tries to get a lease, then it gives up and runs fine
make sure /etc/host.conf has "order hosts,bind" and then put whatever you need in your /etc/hosts file to make it happy
but yeah, I use dhcp for machines that I sometimes take offline
Yes, that is most likely right. I don't know how to dsable it without wiping out the config files I have. I guess I'll just copy them first.
DHCP makes a mess. I hard-configured my main server, but DHCP is still on in the cable modem/router, and I don't think they allow me to configure it from my side. If any machine asks for a lease, it gets assigned my one internal IP, and it starts a war with my main server.
WEll, I think I have some ideas now as to what to do.
you have a static IP from your ISP, right?
Yes, static IP.
dunno what router you have... but my netgear lets me forward incoming traffic to any specific machine (for the server), while still using DHCP
I have dhcp that hands out reserved (192.168) addresses behind my nat
And, the modem/router assigns that address to the first DHCP machine that asks, even if another machine is ALREADY at that addr.
I can tell it "assign MAX address xx.xx.xx.xx.xx.xx to IP address yy.yy.yy.yy where yy is the one I forward incoming traffic to
all the other DHCP IPs can be random
Umm, the odd way Charted does it is no routing, and your internal nodes with assigned static IPs are at their outside IP addr.
not charter - your router
(or don't you have a router?
I have no access to the router. I can't even read the error statistics. According to Charer, if I could access the config page, I could change my IP, etc.
oh, you don't have a router in your house?
It IS a router, but it is not set to do routing for their static IP setup.
their setup doesn't matter
Yes, the router is 3 feet from me, but I am not ALLOWED to access the config page, or really ANYTHING in it.
ok, I asked the wrong question
I should have asked "don't you have YOUR OWN router"
In fact, when I attempt to call up the modem/router's Web address, it will respond to pings, only.
so they gave you a dsl/cable modem _and_ a router...
I am not allowed to provide my own router for Charter static IP. Oh, my main server is also a router. That's what does all the NAT, DNS, etc. here.
Yes, with Covad, I had access to all that config stuff in the DSL modem/router. But, with DSL, you can't change your IP.
Anyway, that's not really that important. Just that it is easier not to use DHCP. Or, at least, it seemed simpler to set up fixed local addresses when I started all this.
I have my own router - I bought it at the computer store, not from the ISP, I own it, and I can do whatever I want with it - its INSIDE the modem, and appears to the ISP to be the only computer in the house
Oh, one other interesting thing - I tried to do threading with my mini-mill and pWM controller, and had to go back to a previous FPGA configuration. I will have to dig into this when I get back from NAMES.
I told it "assign 192.168.1.25 to the box with MAC address foo (my server), and forward all incoming requests there
it assigns 192.168.1.1xx to any other boxes I plug in
Yeah, I do all that on my server and only pay for one fixed IP.
but you don't do dhcp on your server (I mean, you don't have it serve DHCP to your net...)
I don't pay for any fixed IPs, thanks to dyndns, but I can see why you might want one
I don't run a dhcp server at work.. (disabled in the router).
everything is configured manually?
same here, manual.
that works fine until you take one of the computers somewhere (like the CNC workshop)
Yes, I have several hundred page loads a day, at least.
Also, I run my own mail server here.
I just have web, I use fastmail for mail
Usually, reconfiguring was no big deal.
with xp - you can have 2 different configs - on that does dhcp other that does static local address. works great. (have not played with ubuntu to see if I can do something similar)
begone you heathen!
if it doesn't find a dhcp server - it tries the static address.
but yah - it can be a pain.
is "xp" a special distribution of linux, or is it bsd?
Yeah, really! UGH
I use both kinds of operating systems: linux AND bsd
I use microsoft, novell, linux... :)
I have so many Linux versions now it is a mess. I'm still running Red Hat at work!
I finally shut down my Red Hat 5.2/EMC system.
> uname -a
BSD/386 humpy 1.1 0 i386
> ls -la /bin/ls
-r-xr-xr-x 1 bin bin 98304 Feb 2 1994 /bin/ls
Well, I gotta go tinker with this and see if I can shut off the network easily.
this was my first machine when starting my current job - still going on the same installation (not used much anymore)
and good luck
yeah, have fun at names
Thanks, the show is a blast!
cpu = Pentium (unknown speed) model 2, stepping 11
original pentium, F00F bug and all
sounds like the old compile farm - 200MHz Pentiums
about 5 of us used to use this machine, we had X stations
this is probably 133 or 166, don't remember
we still have a 166 upstairs, we run quicken on it
floating point bug? I thought that was only on the 60/90 mhz
thats all we use it for, its not network connected
F00F is the "any user can halt the processor" bug I think
I resisted the urge
then dave has to go and actually give him the link.....

hey Alex. how goes it?
pretty wild lately
lots of things happening very fast.. not much time for anything else
how are you?
SWPadnos: nope, not much yet
fine. just got back from Las Vegas. headed out to Honolulu on Monday :)
an actual vacation with my wife - should be better than (1) a not-quite-vacation with my mother and (2) business trips
that's something :)
I hope so ;)
I'm trying to convince her that she really would like to go to Australia for our 10th anniversary. gotta get her used to snorkeling and stuff :)
that's always hard..
convince her she "likes" or "wants" something
luckily, the weather was cooperating (until this weekend)
several April snowstorms helped a lot ;)
heh, I can imagine
