[Trinux-talk] building a high-performance monitoring system

[Mike P. <MPi...@lg...>]

Hello All,

I'm just getting started with Trinux and have two intended purposes 
for it:  One, to run on older laptops in my IDF closets.  These will
run minicom for console access, as well as give me the ability to 
log in for remote monitoring, as needed.  The second is to build a 
few high-performance monitoring stations that can be used on our 
core switches.  Does anyone have any recommendations for building 
and spec'ing a high-perfomance network monitoring system?  I did 
some quick searches on Tom's Hardware Guide and HardwareCentral.
They are mainly focused on home & wireless networking (although I
did find an interesting article on Tom's HG about laptop NICs:
http://www4.tomshardware.com/network/20011210/index.html).  

If I were to buy the boxes right now, I'd probably either get a 
few cheap Dells and install a gigabit card (or 2) in it, or buy the 
separate components (case, motherboard, CPU, HD, CD/floppy, lots of 
RAM, and 2 or 3 network cards--one or all gigabit.)  I guess my 
primary question is, what network cards are best for capturing a
lot of frames?  I'll probably look primarily for SC fiber cards
since that's what we currently have capacity for.  But I will also
want to install a 100/1000 copper card for later use as we install
more copper gig.

So, if anyone has researched the latest & greatest and could either 
give me advice or point me to some good websites on the subject, I
really appreciate it!

Take care, Mike

[Trinux-talk] SSH Keys

[von K. R. <Rob...@gf...>]

My <mailto:tri...@li...>  previous mail asked
erroneously about SSL Keys, I meant, of course SSH.
The bugbear info wants the keys in the users $HOME directory
This is not quite specified under Trinux. Can someone help and tell me
where they need to be so that an ISO version is ready for remote SSH
admin with RSA Keys after boot ??

I'll find that part in the doc, but I think I said it is done using a
loadlin.exe (which is a boot loader, like grub/lilo) which boots from an
MS-DOS partition.

See 1.4 (Booting from Fixed Partition)

Today I booted to trinux using a floppy. The docs say that it can be

Re: [Trinux-talk] Dropbear SSH Server <= 0.34 Vulnerability

[MP <gr...@tu...>]

Until you get 0.35 working (unless you have already??) can you compile
0.33 with the "fix" mentioned at:
http://www.securiteam.com/unixfocus/5VP0E2AAUS.html  (or maybe even just
compile a version with syslog disabled).  Thats of course if that fix
applies to 0.33.

Thanks. I'll add this to the bug page. I believe I've seen some discussion
on the busybox mailing list about fprintf issues.. 

For those that aren't aware of it. The gnu version of tar is available in
the fileutil.tgz package.

[Trinux-talk] TriNux5250

[Projet G. <pro...@sm...>]

Hello there,

As some of you probably know, I've been working on a tn5250 diskless 
workstation solution based on a mini-Linux distro called Trinux.

Scott Klement's proposal based on PicoBSD is a great thing. Unfortunately, 
that solution was not adapted with my needs since I have to be able to build 
diskless workstations from Windows stations.

I worked on my function keys problem and finally solved it thanks to Matthew 
Franz's help. So, here is TriNux5250, "an automagic access to your AS/400 
from diskless computers".

I wrote a french howto with a kind of english translation but it is not online 
yet. If you want to know more about this solution, send me an email.

Cheers,

Mathieu

[Trinux-talk] busybox-tar crashes

[<HHu...@t-...>]

Hallo,

my busybox-tar crashes with "tar -xvf some.tar" when the file has a  
size of about 300 MByte.
It tells something about GLIBC and "fprint" or "fprintf" - I haven't  
noticed the exact text, sorry.
And then I have to push the reset switch.

On several machines (586 with 32 MByte RAM) it always crashes at the  
same time (at the same file).

Sometimes (in 2 of about 14 tries) it doesn't crash - don't know why.

Maybe it will crash with smaller files - I have seen this behaviour  
with a file of this size.
The "real" tar does work without any problem.

I'm also running dropbear and can connect to it with SSH2.  I'm curious 
though about the last statement that it doesn't require you to have the 
SSH client.  Can someone elaborate?  How would I connect without an SSH
client (not that I need to or even want to...just curious)?

Thanks,

Look at

Maybe that's the way you can use trinux, too.

Re: [Trinux-talk] proxy

[Matthew F. <mf...@ci...>]

For some reason there is a problem with exporting environment variables. So anything you set within
linuxrc or the /etc/init scripts doesn't work.

So the solution is to put it within the getpkg script.

The latest initrd.gz from http://trinux.sf.net/snaps/ has the new version of getpkg.

So basically put your proxy setting in \tux\config\proxy (such as http://192.168.1.10:8080) and it
should work just fine.

Thanks - I have found some more informations:
A better explanation is in the "curl"-manpage.

And then the "snarf"-manpage tells some special variables - may be  
it's better to set the snarf proxy.

I have tried to set the environment variable "HTTP_PROXY", but bash  
didn't accept my tries.
No "set HTTP_PROXY=...". no "HTPP_PROXY=...; export ..."
"set" didn't show the variable.
Strange.

Where could I define those variables: in "/tux/init/last" or in
"/tux/init/postpkg"?

Or just another place?

Re: [Trinux-talk] boot on USB drive

[rick p. <ric...@ho...>]

Hi,

One idea. He had the drive connected to the usb port of some kind of 
machine, Windows or Linux, which allowed him to move files to it.  Can he 
fdisk to the drive and toggle on the "bootable partition" flag??


My CF disk require i do that, iirc.

I'm assuming these drives use the USB storage (which is SCSI, actually)
so you'd need a modified kernel that includes USB and the right SCSI
stuff.

Right now the only way to boot a non-floppy (or CD) drive is to create a
DOS partition and then boot with loadlin. I don't have acccess to any
devices that allow USB booting, so I haven't been able to try this. I'm
assuming FreeDOS won't recognize it as a drive so that wouldn't work,
but perhaps Win98 (can't remember if that has USB support or not)

Booting off a floppy and loading packages from the drive is definitely
doable, though.

Anybody else have any ideas?

Re: [Trinux-talk] proxy

[Matthew F. <mf...@ci...>]

I'll need to update the getpkg script to read /etc/tux/config/proxy
and set SNARF_PROXY to that value.

# snarf --help

This is snarf, version 7.0
usage: snarf [OPTIONS] URL [OUTFILE] ...
Options:
    -a     Force active FTP (default is passive)
    -v     Verbose; print anything the server sends
    -q     Don't print progress bars (compiled default is on)
    -p     Force printing of progress bars (overrides -q)
    -r     Resume downloading a partially transferred file
    -n     Ignore '-r' and transfer file in its entirety
    -m     Spoof MSIE user-agent string
    -z     Spoof Navigator user-agent string

Lowercase option letters only affect the URLs that immediately follow
them.
If you give an option in caps, it will be the default option for all
URLs
that follow it.

If you specify the outfile as '-', the file will be printed to standard
output as it downloads.

You can have as many URLs and outfiles as you want

You can specify a username and password for ftp or http authentication.
The
format is:

    ftp://username:password@host/

If you don't specify a password, you will be prompted for one.

snarf checks the SNARF_PROXY, FTP_PROXY, GOPHER_PROXY, HTTP_PROXY, and
PROXY
environment variables.

snarf is free software and has NO WARRANTY. See the file COPYING for
details.

Yes, I updated the packages and broke them. The old packages are back

those packages. I'm using the dropbear package (it is much smaller) and
it is working great and doesn't require you to have the ssh client.
