| Kamping_Kaiser | Centaur5, check users .xsession (.xerror?) fro errors | 00:19 |
|---|---|---|
| Kamping_Kaiser | do you have sabayon installed? | 00:19 |
| Centaur5 | I'm installing that now | 00:21 |
| Centaur5 | I'm getting this in .xsession-errors xrdb: Can't open display '' | 00:23 |
| Centaur5 | That's rather odd, I wonder what suddenly caused that to happen. | 00:25 |
| Kamping_Kaiser | any hardware/software/configuration chagnges happened recently? | 00:33 |
| Centaur5 | The thin clients have been dead for over a week and I haven't figured it out. The last thing I changed on the server before they died was setting up a chillispot/freeradius server. | 00:41 |

| Delvien | ARP cache,, is that held on my router or the computer itself? | 21:00 |
| Delvien | ok held on the server, | 21:10 |
| Delvien | I need to know how to extend the ARP flush to 48 hours | 21:10 |
| nealmcb | Delvien_: what is the underlying problem pou're trying to solve? | 21:46 |
| nealmcb | *you're | 21:46 |
| Delvien_ | WoL for my vmware server, If the computer is off for some time.. i cant wake it up by sending it a "magical packet" | 21:47 |
| Delvien_ | looks like 5 minutes is the timeframe | 21:47 |
| nealmcb | Delvien_: hmm - sounds complicated :-) how does vmware fit into this? and which sort of magical packet are you talking about, and which host do you want to wake up from where? | 21:48 |
| Delvien_ | no no no, i need to wake up my machinie not nec my vm, | 21:49 |
| Delvien_ | I dont need my vmware server on all the time | 21:49 |
| Delvien_ | which is run off ubuntu-server | 21:49 |
| Delvien_ | so i turn off the machine when im not using it | 21:49 |
| Delvien_ | and when i need it on i use an app called "wakeonlan" so my server will boot up, its a whole thing with wake on lan receives a signal and boots the computer | 21:50 |
| Delvien_ | but the ARP flush is set to 5 minutes, i cant find ANYTHING online on how to extend this to 48 hours | 21:50 |
| Delvien_ | nealmcb do you get what im trying to do? | 21:53 |
| nealmcb | Delvien_: so we can ignore vmware entirely? | 21:54 |
| Delvien_ | yep | 21:54 |
| nealmcb | and you have a client machine (linux?) | 21:55 |
| Delvien_ | thats just what my server runs :P | 21:55 |
| nealmcb | and a server? | 21:55 |
| Delvien_ | ubuntu-server | 21:55 |
| Delvien_ | a client ubuntu-desktop | 21:55 |
| Delvien_ | server is ubuntu-server 7.10 | 21:55 |
| nealmcb | do you get an error message? | 21:55 |
| Delvien_ | woops nick is wrong | 21:55 |
| === Delvien_ is now known as Delvien | ||
| Delvien | nealmcb no, it just doesnt wake up because the settings are flushed, the computer simple just doesnt turn on after a time if i send a WOL packet, | 21:56 |
| nealmcb | so you think you want to have the client machine remember the ethernet address longer than 5 min? but it doesn't complain about not knowing it? | 21:57 |
| nealmcb | if this was a common problem with WoL I'd expect them to suggest a solution.... | 21:58 |
| nealmcb | so what is unusual about your configuration? | 21:58 |
| Delvien | nothing, some people have the same problem but like always, they never post their solutions | 21:58 |
| * nealmcb nods | 21:58 | |
| Delvien | ARP is automatically set to clear within a few minutes or hours | 21:58 |
| Delvien | i can run command "arp" while the computer is on, and man arp shows nothing that will help | 21:59 |
| Delvien | im at a loss | 21:59 |
| nealmcb | does a packet get sent? e.g. does ethereal show anything? | 22:01 |
| * nealmcb wonders why there is no error message from wakeonlan | 22:01 | |
| Delvien | there wouldnt be | 22:02 |
| Delvien | its not accessing the computer itself when its off. its just sending it a packet | 22:02 |
| Delvien | saying "hey wake up" | 22:02 |
| Delvien | there would be no response because the eth card is "sleeping" and only accepts a packet to signal the boot | 22:02 |
| nealmcb | I was assuming that the problem was that the arp cache is on the client didn't have the sleeping server's mac address - right? | 22:03 |
| nealmcb | s/is on/on | 22:03 |
| Delvien | it has it , but only for a certain amount of time | 22:03 |
| nealmcb | you run wakeonlan on the client, right? | 22:03 |
| Delvien | ye | 22:04 |
| Delvien | yep | 22:04 |
| nealmcb | so if it sends a packet, it is a problem on the server end, and if it doesn't send a problem, it is a client / network issue | 22:04 |
| * nealmcb forgets most of the details of arp caching, frankly.... | 22:04 | |
| nealmcb | we once had to run a rarp daemon, but since then, most "arp" problems turned out to actually be other networking issues | 22:05 |
| Delvien | ARP caching keeps the mac address and the ip address so if your system goes down for a short amount of time it will keep the same information, the MAC address of course would all stay the same, but the IP would remain | 22:05 |
| Delvien | err wouldnt remian for IP | 22:05 |
| Delvien | remain | 22:05 |
| Delvien | there is a way to extend that ARP caching, but i dont know how to in linux | 22:06 |
| nealmcb | what kind of network? what kind of router(s)? | 22:08 |
| Delvien | just LAN atm | 22:09 |
| Delvien | wrt54g | 22:09 |
| Delvien | nealmcb and i know its something in ubuntu-server i can change because if i disconnect the power then turn it off just far enough to get to grub turn it off, and send the WOL it doesnt boot | 22:15 |
| Delvien | but if i let it boot up then shut down, it will wake with the packet | 22:15 |
| nealmcb | wired lan? I wonder if the router can be configured to help | 22:17 |
| nealmcb | I don't see what the server has to do with it - it is asleep.... | 22:17 |
| nealmcb | I would think you'd be changing the arp cache time on your client | 22:18 |
| nealmcb | the server might ignore wol when already in grub or something.... | 22:19 |
| nealmcb | Delvien: what command line do you use to wake it up - do you give it an ip address or a mac address? | 22:24 |
| nealmcb | seems like you just need to remember the mac yourself.... | 22:24 |
| Delvien | nealmcb right i thought that to but what WOL does is keeps power coming to the ethernet , so it can receive a packet, which sends a signal to the mobo to boot | 22:24 |
| Delvien | wakeonlan -i 65.186.88.xx -p 9 00:11:5B:14:4A:xx | 22:24 |
| Delvien | put x's in there so no ones gonna try and hack me :P | 22:25 |
| Delvien | im testing something, hopefully this will work | 22:25 |
| nealmcb | so why do you need an arp cache if you give it the mac address? | 22:25 |
| Delvien | put wol into "d" mode | 22:25 |
| Delvien | if the cache is cleared its not on the network technically | 22:26 |
| Delvien | therefore the router is like "huh" and throws the packet away, course, you wouldnt get an error | 22:26 |
| Delvien | unless im wrong | 22:26 |
| nealmcb | I think the arp cache is just a local thing used to construct the packet. if you give it the mac addr, it shouldn't need the cache | 22:26 |
| Delvien | the cache is on the server not the client | 22:26 |
| nealmcb | no - the router would have its own arp cache | 22:26 |
| nealmcb | the cache is on each local machine, whether it is a client, server or router | 22:27 |
| nealmcb | but as I say I don't think you need it.... | 22:27 |
| Delvien | i guess you are right | 22:28 |
| Delvien | there is a parameter in the router named "ARP flushing time" that is defined in 5 minutes. | 22:28 |
| nealmcb | and sniffing your network will tell you if the packet is being sent | 22:28 |
| Delvien | I have no idea how to change the ARP flushing time | 22:28 |
| nealmcb | can you change that? | 22:28 |
| Delvien | weird cant find an option | 22:30 |
| nealmcb | if it is a switched network I guess the router might need to be involved, but that would seem error-prone.... | 22:32 |
| Delvien | nealmcb think if i didnt have it on DHCP would it be a problem ? | 22:32 |
| nealmcb | is it getting the same ip address each time? | 22:33 |
| Delvien | yeah | 22:33 |
| Delvien | only 2 on the lan atm | 22:33 |
| Delvien | my client and server | 22:33 |
| nealmcb | then the answer should be "no it wouldn't matter" | 22:33 |
| nealmcb | but of course most of my answers are based on theory, not practice :-) | 22:33 |
| proprietarysucks | anyone know how to get 3ware card working on ubuntu 6.10 server ? | 22:36 |
| nealmcb | !hardware | 22:37 |
| ubotu | For lists of supported hardware on Ubuntu see https://wiki.ubuntu.com/HardwareSupport - To help debugging and improving hardware detection, see https://wiki.ubuntu.com/DebuggingHardwareDetection | 22:37 |
| proprietarysucks | https://wiki.ubuntu.com/DebuggingHardwareDetection is a blank page with how to file a bug report | 22:44 |
| proprietarysucks | and the first one doesn't have it | 22:45 |
| proprietarysucks | this is 9650SE | 22:45 |
| proprietarysucks | the instructions from 3ware are: http://www.3ware.com/KB/article.aspx?id=15054 | 22:45 |
| proprietarysucks | however it's not working as expected; something is different | 22:45 |
| Delvien | nealmcb was seeing if i could upgrade my routers firmware, of course my router is the ONLY one on the list i have to jump through a flaming hoop to flash | 22:45 |
| proprietarysucks | specifically step 7 | 22:46 |
| nealmcb | proprietarysucks: hmm - scary set of instructions.... | 22:54 |
| proprietarysucks | here's the problem I run into | 22:54 |
| proprietarysucks | When I go back to tty1 to 'select' 3w_9xxx, there's nothing to select | 22:55 |
| proprietarysucks | it's still on the same screen it was before | 22:55 |
| proprietarysucks | in other words, the instructions suggest the installer will fail to find drive and then ask you to load a module | 22:55 |
| proprietarysucks | however in reality the installer doesn't seem to be doing that | 22:55 |
| proprietarysucks | I have to have this done on 3 systems asap :( | 22:56 |
| nealmcb | proprietarysucks: sorry - not my area of expertise :-( | 22:57 |
| nealmcb | perhaps ask 3ware for help or ask them to release the source for the driver and build your own kernel.... | 22:58 |
