[00:00]<vd2r>I want a minimal laptop type thing that does console and telnet/ssh type stuff.
[00:00]<vd2r>would be nice
[00:04]<fncu>Linux?
[00:05]<vd2r>perhaps.
[00:05]<vd2r>but I'm thinking even more minimal.
[00:05]<vd2r>smaller. longer battery life. built in transformer and takes standard pc power cables.
[00:05]<vd2r>touchscreen/soft keyboard.
[00:06]<fncu>it would have to run some embedded os
[00:06]<fncu>to give you tcp/ip for SSH
[00:06]<fncu>linux would be a good candidate..combine that with a tablet pc
[00:06]<bsdrgdjg>get one of those old translators, they have full keyboards. you might be able to rig something up
[00:07]<fncu>does it need to be portable?
[00:07]<fjzvxnz-wjzc>i could probably design something for you.
[00:08]<fjzvxnz-wjzc>having it accept IEC320-P10 might not be a good idea though. Those connectors are typically pretty large.
[00:08]<fjzvxnz-wjzc>Do you care if it has a full-size keyboard, or do you want it really small?
[00:09]<fncu>you an EE?
[00:09]<fjzvxnz-wjzc>i;ve done some work with it. I could do everything but fab it, basically.
[00:09]<fjzvxnz-wjzc>what would be better is to find some sort of pre-made small embedded system and work around that
[00:09]<fjzvxnz-wjzc>something ARM based, perhaps
[00:10]<fncu>yeah
[00:10]<fncu>why ARM tho? power consumption?
[00:10]<fjzvxnz-wjzc>yeah, fast and low-power
[00:11]<gndyvx>i always wanted a small console device
[00:11]<gndyvx>for when shit hits the fan
[00:12]<gndyvx>i don't want to wait for a pc to boot
[00:12]<ljanuz>they have linux for arm, and you can make a very minimal kernel for quick boot
[00:12]<fncu>yeah
[00:12]<fncu>i have linux running on a NeTTwinder (StrongARM)
[00:13]<fjzvxnz-wjzc>yeah, boot in under 20 seconds or so
[00:13]<fncu>you can boot the netty off of a 9vt battery
[00:14]<fjzvxnz-wjzc>what is a netwinder?
[00:15]<ljanuz>buy a palm, put linux on it, then install a usb to ethernet adapter
[00:15]<ljanuz>buy an ebay palm
[00:16]<ljanuz>ohh looks like serial only
[00:16]<fncu>the netwinder is a small linux server made by San Mehat (now at google) aka NeTTwerk
[00:16]<fncu>he ported linux to the StrongARM while at Coral, and made that little box
[00:17]<fncu>http://www.netwinder.org/
[00:17]<fncu>http://dev.gentoo.org/~vapier/pics/arm-netwinder/netwinder.jpg
[00:18]<fncu>it has an onboard dsp, two ethernet ports, scsi drive, and a slider on the front panel that controls your volume for the soundcard
[00:19]<sycn>i put two VWIC2-2MFT-T1/E1 cards in a 2821 - show diag sees them, but i can't enter any 'controller' commands. do i have to activate them or something?
[00:20]<gndyvx>http://cgi.ebay.com/Psion-Netbook-Pro-BNIB-Laptop-PDA_W0QQitemZ290009538241QQihZ019QQcategoryZ38331QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[00:21]<gndyvx>http://linux-7110.sourceforge.net/
[00:26]<gndyvx>sike: you need the card type
[00:26]<gndyvx>since you can do either t1 or e1
[00:27]<sycn>nemith: this is my first stab at a T1/E1 card...
[00:27]<gndyvx>sike: card type t1 ? in ios
[00:28]<sycn>ah...
[00:28]<gndyvx>that will get you the controller which in turn will get you the physical interface(s)
[00:28]<fncu>that is a nice lookin machine
[00:28]<sycn>nemith: thanks
[00:28]<gndyvx>leku: yeah
[00:29]<gndyvx>hell leave wince on it
[00:29]<fjzvxnz-wjzc>leku: those are pretty expensive little boxes
[00:29]<fncu>i bet
[00:31]<fncu>wait
[00:31]<fncu>179 euros?that's not bad at all
[00:31]<fjzvxnz-wjzc>i'm looking for something small, low-power, with two ethernet ports and a decent amount of RAM and disk, which I can use to off-load a bunch of mundane tasks I don't want my personal machine to do.
[00:31]<fncu>does it have to hve a screen?
[00:31]<fncu>you could get a netwinder
[00:31]<fjzvxnz-wjzc>leku: uhh, i see $999 for the desktop and $1699 for the rackmount
[00:31]<fncu>or buy mine 8)
[00:31]<fncu>http://cgi.ebay.com/Psion-Netbook-Pro-BNIB-Laptop-PDA_W0QQitemZ290009538241QQihZ019QQcategoryZ38331QQssPageNameZWDVWQQrdZ1QQcmdZViewItem#ebayphotohosting
[00:32]<fncu>213 euros in dollars is 266.67600 USD
[00:32]<vcul>that's cheap
[00:35]<fjzvxnz-wjzc>oh, the psion thing
[00:35]<fjzvxnz-wjzc>yeah, that does look pretty sweet
[00:35]<fjzvxnz-wjzc>i don't think i could tolerate the wince interface though
[00:36]<fjzvxnz-wjzc>it'd be fun getting the kernel and utilities to fit in 32MB FLASH.
[00:37]<fncu>haha
[00:37]<fncu>they have a linux page for it
[00:37]<fjzvxnz-wjzc>oh, well then i'm set
[00:37]<fjzvxnz-wjzc>i don't really have the money for it right now though :
[00:46]<ljanuz>any good way to make cisco always return the loopback address instead of whatever address cisco feels is right in a traceroute?
[00:48]<gndyvx>it's should be the source interface
[00:49]<ljanuz>yeah, and I wanted it to return a loopback ip
[00:49]<gndyvx>it breaks icmp
[00:49]<ljanuz>why?
[00:49]<gndyvx>traceroute is nothing on the router
[00:50]<gndyvx>it is just random udp packets sent to the destination ip address with the TTL incresed
[00:50]<ljanuz>yes, I understand traceroute
[00:50]<ljanuz>but the router can return an icmp unreachable from any source
[00:50]<ljanuz>s/the/a good
[00:50]<gndyvx>well the ICMP time-exceeded message should come from the interface it was arrived on
[00:50]<ljanuz>err time exceeded
[00:52]<gndyvx>but the RFC does state
[00:52]<gndyvx>The address of the gateway or host that composes the ICMP message.
[00:52]<gndyvx> Unless otherwise noted, this can be any of a gateway's addresses.
[00:52]<ljanuz>exactly, so I want it to return it's loopback ip, not the interface ip
[00:57]<gndyvx>well i don't think you can
[00:58]<ljanuz>me neither... not easily. policy route set ttl 1, then forward to the loop0
[00:58]<ljanuz>blah
[00:58]<gndyvx>but pbr wouldn't change the source ip address
[00:58]<ljanuz>we did that on some linux firewalls to make then invisible
[00:58]<gndyvx>hmm
[00:58]<ljanuz>source ip isn't the prob
[00:59]<gndyvx>pix used to do that by default
[00:59]<gndyvx>just put all of your interfaces in DNS
[00:59]<ljanuz>it'd send it back to the correct source, the loop0 iface would be the iface that it decriments ttl to 0, then the router would respond from loop0 with icmp time-exceeded
[00:59]<ljanuz>that's plan 2 :)
[00:59]<gndyvx>right
