Their route tables don’t update accordingly. Why not? [00:14:13] <obamaHit1er> Do modern kernels not obey ICMP Redirects? [01:19:33] <syb> hi [01:29:46] <jadon> i have a problem with getting my laptop to stay connected to my router it connects then dissconnects and reconnects for a good half hour before connecting stabely [01:31:45] <jadon> anyone? [01:31:49] <jac099_> @jadon: hows signal strength? whats the output of ‘iwconfig’ ? [01:32:55] <jadon> signal is perfect [01:33:35] <jadon> wlan0 IEEE 802.11bg ESSID:”omnomnom” [01:33:36] <jadon> Mode:Managed Frequency:2.462 GHz Access Point: 00:24:01:67:11:81 [01:33:36] <jadon> Bit Rate=11 Mb/s Tx-Power=20 dBm [01:33:36] <jadon> Retry long limit:7 RTS thr:off Fragment thr:off [01:33:36] <jadon> Power Management:off [01:33:36] <jadon> Link Quality=61/70 Signal level=-49 dBm [01:33:38] <jadon> Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 [01:33:42] <jadon> Tx excessive retries:0 Invalid misc:0 Missed beacon:0 [01:33:59] <jac099_> yeah.. signal looks good.. [01:34:42] <jadon> i can be next to the router and it will do its thing [01:34:43] <jac099_> what do you mean by disconnect? Is your LAN getting disconnect or some specific service? [01:34:54] <fluter> jadon, 61/70 is perfect?? [01:35:03] <fluter> its not 70/70 tho [01:35:07] <jadon> let me exspain the symptions [01:35:13] <jadon> i boot up [01:35:22] <jadon> wifi starts to auto connect [01:35:36] <jadon> it connects and i can browse the web [01:35:51] <jadon> around 30 seconds later it disconnects [01:35:57] <jadon> and starts to reconnect [01:36:17] <jadon> repeat last 3 steps for a long time [01:36:35] <jac099_> Did you conclude this based on ping or some other way? [01:37:00] <jadon> well it pops up and says wifi disconnected and i cant load any websites [01:37:34] <jac099_> Do “ping and leave it running.. see how many packets drops are there [01:37:50] <jadon> if i play with the RF-kill switch on the laptop and ifconfig wlan0 up/down after a while i get a stable connection [01:38:26] <jac099_> what does “iwlist scan” says? [01:38:32] <jadon> i did the router ping a while ago and it was dropping all the packets while it said it was disconnected [01:38:50] <jadon> wlan0 Scan completed : [01:38:50] <jadon> Cell 01 – Address: 00:24:01:67:11:81 [01:38:50] <jadon> Channel:11 [01:38:50] <jadon> Frequency:2.462 GHz (Channel 11) [01:38:50] <jadon> Quality=64/70 Signal level=-46 dBm [01:38:50] <jadon> Encryption key:on [01:38:52] <jadon> ESSID:”omnomnom” [01:38:54] <jadon> Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s [01:38:56] <jadon> 9 Mb/s; 12 Mb/s; 18 Mb/s [01:38:58] <jadon> Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s [01:39:00] <jadon> Mode:Master [01:39:02] <jadon> Extra:tsf=0000000003a015ce [01:39:04] <jadon> Extra: Last beacon: 95244ms ago [01:39:06] <jadon> IE: Unknown: 00086F6D6E6F6D6E6F6D [01:39:08] <jadon> IE: Unknown: 010882848B968C129824 [01:39:12] <jadon> IE: Unknown: 03010B [01:39:14] <jadon> IE: IEEE 802.11i/WPA2 Version 1 [01:39:16] <jadon> Group Cipher : CCMP [01:39:18] <jadon> Pairwise Ciphers (1) : CCMP [01:39:20] <jadon> Authentication Suites (1) : PSK [01:39:22] <jadon> IE: Unknown: 2A0100 [01:39:24] <jadon> IE: Unknown: 3204B048606C [01:39:26] <jadon> IE: Unknown: DD180050F2020101070003A4000027A4000042435E0062322F00 [01:39:28] <jadon> IE: Unknown: DD0900037F01010000FF7F [01:39:30] <jadon> IE: Unknown: DD0A00037F04010004000000 [01:39:33] <jadon> like i said right now its fine [01:40:47] <jac099_> basically, you need to conclude if its wireless router issue specific to link or something else.. for exa: your IP is not getting registered properly due to conflict [01:41:23] <jadon> oh thats the other thing its specific to this router but it been fine on the router before [01:41:37] <jadon> like for a month or 2 then this started [01:42:24] <jadon> it seems to coinside somewhat with my adding a game server connected VIA a DD-WRT client bridge [01:42:35] <jac099_> what router? Do you get any hints from router admin webpage? it must be like.. http://192.168.1.1/ and then some login.. [01:42:55] <Spice_Boy> jadon, I had a similar issue [01:43:00] <Spice_Boy> when I changed the wireless driver [01:43:13] <jadon> i have RTL1817B drivers [01:43:15] <Spice_Boy> it then does similar, maybe not quite as bad [01:43:25] <Spice_Boy> and it became very fussy about the AP settings [01:43:41] <Spice_Boy> I have to have WMM off, and SSID broadcast on for it to even connect. That was not an issue with a different drive [01:43:44] <Spice_Boy> *driver [01:43:47] <Spice_Boy> just a thought [01:44:07] <jadon> WMM? [01:44:10] <jadon> SSID broadcast is on [01:44:45] <jadon> jac what do you mean by hints? [01:45:29] <jadon> i have some logs [01:45:30] <jac099_> like.. network stats [01:45:43] <jac099_> I gtg.. will be back in 1-2 hrs [01:45:53] <jadon> UDHCPD sendOffer : client is in lease/offered table [01:45:55] <jadon> lots of that [01:46:09] <jadon> with this [01:46:13] <jadon> UDHCPD sending ACK to 192.168.0.101 [01:47:02] <jadon> what should i do to log more info client side? [01:47:14] <jadon> for when its being a bugger [01:48:48] <jadon> encryption is AES only should i make it AES-TKIP? [01:49:59] <Spice_Boy> if your client can do AES, then leave it AES [01:50:34] <jadon> well im wondering if it could be haveing trouble with AES [01:50:51] <jadon> im in said problem laptop now with AES [02:30:29] <rhett> i have a local home network with 2 linux boxes, and i can see their ip addresses, but they aren’t finding each other by hostname [02:30:29] <rhett> how do I made that work? [02:30:29] <jadon> exsplain finding eachother? [02:30:29] <rhett> ping otherhostname returns the local ip [02:30:29] <rhett> jadon, one is addr:192.168.0.106 the other is .108 currently [02:30:29] <rhett> but i use dhcp [02:30:29] <rhett> with a router [02:30:29] <jadon> so you ping the 106 from the 108 and… [02:30:29] <rhett> jadon, it works [02:30:29] <rhett> but if i say ping otherhostname, it says “ping unknown host” [02:30:31] <jadon> what does otherhostname do exactly? [02:30:31] <jadon> i get the same thing [02:30:33] <jadon> what were you exspecting otherhostname to give you? [02:30:33] <rhett> look [02:30:33] <rhett> I have 2 linux ubuntu computers [02:30:33] <rhett> i want my dns to find the ip by hostname [02:30:33] <jadon> yes i see that i have the same as well [02:30:33] <jadon> (laptop and desktop/server) [02:30:33] <rhett> how do i set up resolv.conf to do that? is that where it should go? [02:30:36] <rhett> my resolv.conf says this: domain austin.rr.com [02:30:36] <rhett> search austin.rr.com [02:30:36] <rhett> nameserver 192.168.0.1 [02:30:36] <jadon> bluuu thats out of my league [02:30:36] <rhett> ok, thanks anyway [02:30:36] <jadon> sorry i couldnt be of more help [02:30:36] <jadon> but why dont you just use the IP [02:30:36] <jadon> instead of hostname [02:30:36] <rhett> because i’m using dhcp [02:30:36] <rhett> so the ip can change [02:30:36] <jadon> set static IP adresses [02:30:36] <jadon> works for me [02:31:29] <rhett> yeah that would work [02:33:28] <jadon> well i got to go sleeping time then crunch on finals paper [02:43:36] <booginga> hey all i have a weird question that i haven’t been able to solve. I want to get the route from a remote machine to a remote ip. so something like traceroute but i want to force it through a speci<booginga> I’m running centos I’m I’m willing to install whatever or go to windows if that is needed. just need a push in the right direction if that direction exists [02:44:49] <woggle> It’s not generally possible to do that. [02:46:12] <woggle> In some cases, you may be able to map enough of the network from traceroutes and similar tools to guess the path. In other cases, you might be able to reflect traffic off the remote machine or somet<booginga> i see well i guess that makes sense [02:47:48] <woggle> For wide-area Internet paths, there are some databases from organizations who’ve done a lot of traceroutes and thus can guess a reasonable number of plausible partial paths. [02:50:36] <booginga> what should i look at to find out more about reflecting off a remote machine? [02:51:24] <woggle> The most straightforward thing to do would be a traceroute or record-route ping with loose source routing, but this is very likely to be filtered and/or disabled. [02:51:39] <woggle> (Loose source routing is an IP option.) [02:52:27] <woggle> Where not filtered or disabled, you’d probably need to mention a router and not an end-host as the LSR target. [02:54:28] <booginga> ok great thanks for pointing me in the right direction that should get me something to look for on google [02:55:59] <woggle> I should note that LSR is likely to be filtered _outgoing_ from most connections, especially consumer ones. [03:01:03] <woggle> Without something like LSR, the best you can get reflected through the host is probably just going to be timings and loss rates to or from target hosts. [03:02:03] <woggle> I suppos it’s also worth pointing out here that Internet routes aren’t symmetric, so you should figure out which route you want, too. [03:08:33] <booginga> thanks for the help i have plenty to read now [04:35:03] <ZeitFight> Hello! I want to learn the basics of networking but can’t find any book on it. Any recommendations? [05:07:59] <X0Rc0re> hello [05:08:04] <X0Rc0re> can someone help me please? [05:08:20] <X0Rc0re> i need to forward port 2121 on my comp [05:08:21] <wooter> whats the prob [05:08:40] <X0Rc0re> how would i do that? [05:08:47] <wooter> windows ?
