a do nothing shell ?
Hi bods, I wish to create a guest account on a machine where that account exists purely for the ability to connect via SSH and create tunnels. There is no requirement for an interactive shell on the host machine. What then I can I specify as the guest accounts shell ??? I have noted various 'restricted shells' such as rbash and rssh but they still do more than I need. Really all I want is MOTD and logout. What do you suggest ? Cheers, Chris

Re: OT: Cabling to a shed
Robert Fisher wrote: -Original Message- From: Volker Kuhlmann list0...@paradise.net.nz Yes. For starters, the power cables are legally required to be in conduit of their own, and with good reason. Not quite correct. Separation is mandatory and protection is recommended. Protection can be as simple as tanalised timber above the cable. Of course conduit is highly recommended though for lots of good reasons. Rob When I 'undergrounded' my street feed I was advised to bury the cable directly in the ground for the cooling effect of the earth. If I had used a conduit then I would have had to use the next larger wire size. The price difference was significant to me at least. I imagine for 3-phase the difference will be even greater.

NFS exports with wildcards
Hi team, I had a curious problem with an attempt to create NFS export using wildcard declared hosts. The man:exports page has this to say: wildcards Machine names may contain the wildcard characters * and ?. This can be used to make the exports file more compact; for instance, *.cs.foo.edu matches all hosts in the domain cs.foo.edu. As these characters also match the dots in a domain name, the given pattern will also match all hosts within any subdomain of cs.foo.edu. so I set up an export thus: /tmp *.cs.foo.edu(rw,sync) and when I tried to mount it from a box with hostname='mybox' and dnsdomainname='mybox.cs.foo.edu' I get a permission denied error. But if export thus: /tmp mybox.cs.foo.edu(rw,sync) I can mount the export no problems. From the server and the guest I can ping either 'mybox' or 'mybox.cs.foo.edu' without problem. I tried even adding a reverse lookup for mybox's ip - but no change. Any wisdoms out there in *nix admin land ? : ) ChrisB
[SOLVED]Re: NFS exports with wildcards
I found the problem: I mention below that I tried Reverse DNS. In fact I stuffed up the reverse zone file by leaving off the trailing dot of the domain name! so I had the client IP resolving thus: xen1:~# host 10.64.9.15 15.9.64.10.in-addr.arpa domain name pointer leela.xen.au.ivc.15.9.64.10.in-addr.arpa.

visibility memory useage in elf binaries
Hi team, I am looking for a utility that will give me a really powerful
look into the memory usage of my elf binaries
What I want to do is something like this:
first extract all the symbols and size information using nm -S,
then graph the information with an expression in section terms ie
(.text|.rodata) vs. an expression in symbol terms ie. symbols starting
('rtos_[.+]|gui_[.+])
thus the above example would show me the combined ROM useage of all
the sybols being with 'rtos_' or 'gui_'.
even cooler would be then to present the information in a pie chart
fromat like 'filelight' or konqueror's 'radial view' does with the
ability to drill down and look in more detail at a given area.
If you are a programmer and can identify the need I refer to above what
are the tools you are already using to glen this kind of analysis of
memory usage in your programs ??
What I am aiming at here is a powerful tool which will help show me
where to take a scalpel to a slightly overweight binary constructed from
1000 objects.

Re: Alcatel Speedtouch Pro (ADSL Router)
I am currently running a PRO - have been for years. The difference to the HOME is the addition of a NAT router on the PRO. If you use it in this mode then there is nothing to setup in linux other than basic network configuration ie. a valid dhcp client server relationship or manual ip config etc. The HOME requires that you to set up pptp on a your linux box. In many firewall distros (such as IPCop) this is done for you and you simply tell the firewall which pptp phnone book entry to use. So if you use the PRO in PPTP mode it's like the home and I hear there is a hack somewhere to turn a HOME into a PRO. So... the easiest setup with linux is to use a PRO in ppp mode with NAT routing and DCHP DNS services active and your machine as DHCP client - like that it will 'just work' until you want to run any internet servers at which point you can read http://www.nzdsl.co.nz/howtos/Alcatel/alcatelpinholing.html in order to open the outside ports which you desire to serve from - eg http, smtp, bittorrent etc I have run the PRO like this, in PPTP with IPCop, and in BRIDGE mode with a WRT54G in France (but I get get the same thing to work here!). If you need to swap notes just ask. Regards, Chris Kerry Mayes wrote: Has anyone out there set up one of these? I know they are really old but should still work alright.

Re: can xp be loaded by default and not opensuse?
If you are using the 'grub' boot loader then simply change the 'default=?' line in /boot/grub/menu.lst to indicate your XP entry in the same file. If you use the 'lilo' bootloader then wait until a lilo user chimes in. Chris Reg wrote: Can XP be loaded up at startup by default rather than Opensuse? Just to make my question more clear, I am talking about when the computer starts and you get to the boot menu where you have to manually choose windows, if you don’t it will automatically load Opensuse.

nVidia teething issues
I have recently moved over from a long tradtion with ATI to my first nVidia card (GeForce 7100GS) and I have noticed the functionality of 'X -configure' is somewhat less than I am accustomed to with the ATI cards; i.e. with the ATI cards when I issue the above command X gives me a config with my monitor details well spec'ed and X functions in a great variety of modes and refresh rates. With the nVidia card X can't detect any details of the monitor and X fucntions by default in just one mode/Vrate: 1280x1024/75Hz unless I hand code other modes into the .conf file. Is this normal behavior for nVidia cards ? Do I have to configure all of the modes and the monitor details by hand ? Xorg is v. 7.1.1 nVidia-driver is v. 1.0.8776 Cheers, Chris

Need help with Spamassassin rules....
Hi guys, a continuous torrent of spam has been driving me to distraction recently and the out of the box configurations seem to be loosing ground so it come time for me to learn about writing custom rulesets for spamassassin. Unfortunatly the first rule I want to write appears to be a bit more than a simple regex : ( Here's what I have observed about the bulk of the spam that comes my way and what differentiates from the ham: Received: from YOUR-4ECD8HHOVM.druuvln.net (unknown [70.106.176.148]) by mail4.zoneedit.com (Postfix) with ESMTP id 027C1A529F for [EMAIL PROTECTED]; Mon, 24 Jul 2006 10:15:41 -0400 (EDT) In the received headers for spam the sending domain is almost always forged and for ham I can find no example of this nor any valid reason for doing so. First job; there are many Recieved headers and the one that is of interest is where the mail enters my mail domain and can be identified by 'mail?.zoneedit.com' in the second line. Then; pull the claimed sender domain e.g. druuvln.net and comapre it to a hostlookup on the real sender ip [70.106.176.148] or the zoneedit supplied lookup 'unknown', then when they don't match add LOTS of points to the spam score Does anyone know if a spamassassin rule can be this sophisticated or is it necessary or is there even a way to break out into some script for this test ??

In over my head with bash scripting....
Hi team
I have been whipping up a wee bash script to empty out the photos of my
digital camera to my storage device. It runs from ivman when the camera
is plugged in and the idea was to have as little user intervention as
possible. It started off as a small bash script that was all right if
you were watching on a terminal, but not robust enough to run unsupervised.
I have come unstuck when trying to deal with CLI programs that expect an
input on stdin but give me a question on std{out/err} that has no linefeed.
I have found it very tricky indeed to read stdout when there is no LF.
Here is some example code:
#/bin/bash
# init some files and a pipe to play with
touch file{1,2}
mkfifo pipe1
catch_question()
{
# with this read loop I would like to read from stdin (the std{out,err}
from cp)
# problem is with the 'file exists, overwrite (y|n)?' type questions a
LF is often
# not sent in order the the user input occurs on the same line.
# hence 'read' seems unusable in this context ?
while read LINE
do
# if I find something of concern then I will do my own UI for
the question?
if echo $LINE|egrep 'overwrite.+?' /dev/null
then
if kdialog --yesno $LINE # your choice of UI here
then
# and copy a response to the pipe for the blocked cp
echo y pipe1
else
echo n pipe1
fi
fi
done
}
# here I have a cp that complains of existing files
# stderr and stdout are combined and piped to 'catch_question'
# cp is expecting responses from the named pipe 'pipe1'
cp -iv file1 file2 21 pipe1 | catch_question
#clean up
rm file1 file2 pipe1
So, if anyone has some ideas about how to read 'incomplete' lines from
stdin or approaches to the task above I'd love some new ideas.
Meanwhile I'm off to 'man expect' - I may be some time!

module load order
When my gentoo(kernel 2.6.14) system boots up coldplug detects the pcmcia-usb card attached and loads both ohci_hcd and ehci_hcd in that order as the usb host drivers. Now the problem is that if the attached usb peripherals are USB1.0/2.0 compatible they are first bound to the ohci_hcd(USB1/full_speed) driver and not the ehci_hcd(USB2/high_speed) driver resulting in the dictated reduced performance. I could remove the ohci_module from the kernel build, but I am sure there is a more elegant solution to specifying the discovery order to hotplug, I'm just not sure what it is yet. Any takers ? : ) ChrisB

I am about to choose a switch for a primary school network that I am building, the network has 14 LTSP clients + 4 standalone off a sever with GBIC (1000Mbps).

The setup: I've got the LTSP running and currently the client machine boots from floppy. Unfortunitly the floppy drive came from my main server machine and it's getting annoying swapping it back and forth. So the obvious solution is to keep the drive in the remote client and then be smart and access it remotely. Having failed the 'be smart' criteria I'm wimpering for how-elp?? Synco Actually, the obvious solution is to install a boot ROM in the network card in the terminal machine and use that to boot it. The floppy drive can then be moved back to the server. SICOM in Antigua St. have the facilities to program PROMs. The other easy solution is to get yourself another floppy drive. $5 for a s/h one wouldn't break the bank would it? The truely horrid, or depending on tour point of view, high powered geek solution is to fiddle about with the LTSP file set so that you can remote mount the floppy in the terminal on to the file system in the server using NFS or something. imho time consuming and definitely _not_ recommended. I haven't set it up yet but I will be following these directions: http://ltsp.org/documentation/floppyd.html to access the local floppy on a ltsp client from programs running on the server - which is what you want to do I think.

I've got a standard IDE DVDROM drive (cos it was about $15 more expensive than a new CDROM drive) and I can't get it to play DVDs. The machine is a celeron 1Ghz with a budget motherboard, via chipset, and trident graphics. The DVD is slave on the second IDE bus (/dev/hdd) with an HP CDRW as /dev/hdc I've tried xine, mplayer, ogle, etc. as players, and lsdvd and dvdbackup to simply read some info. I can mount a CDROM fine. I can mount a DVD fine too, but some chapters don't read. For example: tramadol:/dvd/VIDEO_TS# file * ... VTS_02_5.VOB: MPEG system stream data VTS_02_6.VOB: ERROR: cannot read `VTS_02_6.VOB' (Input/output error) ... Showing the disk is mounted. /dev/ide/host0/bus1/target1/lun0/cd 7.7G 7.7G 0 100% /dvd One thought was that there was no region set, so I set it to zone 4 using regionset, but that made no difference. Most errors look similar to this, so I suspect the problem lies with libdvdcss and friends. tramadol:~# lsdvd libdvdread: Using libdvdcss version 1.2.5 for DVD access libdvdread: Can't seek to block 256 libdvdread: Can't seek to block 256 libdvdread: Can't open file VIDEO_TS.IFO.

Re: DVDs under Linux]
I first got mplayer going in console with framebuffer and then worked my way through the X players. Play with the switches in mplayer and try playing the audio only or the video only...

Question of how to burn it though: Do corpcons sell to Joe Bloggs? In what quantities? TasTech min qty is 20 for $30. Enough interest for 20? I brought 10 from corpcons no trouble - I never tried asking for 1, but I'll sell anyone 1 (pre burnt if you wish) for a beer or less. Technical point: corpcons says theit business blanks are 45MB, but the lnx-bbc image is 50MB. Anyone know what the real story is?

grep or sed regex ?
In egrep or sed what is the metacharacter to match _across_ a newline i.e. something like 'line1chars.\n.line2chars' ? $ matches the end of a line, but I want to match several lines for search and replace TIA /cb
Re: Mirroring Gentoo on local drive prior to installing
At the Gentoo home thier is a document about creating a local gentoo mirror.

Re: ADSL modems or routers with IPCop - war stories and medals??
I used to use an Alcatel SpeedTouch in PPP routing w/NAT as a gateway for my network - but after a _MASSIVE_ incident with my jetstream billing I have found that I had needed much better logging and ipaccounting to protect my ass. I have subsequently installed an IPCop gateway which talks to the alcatel in PPTP bridging mode. I now have a record of every packet in or out of my network. Support for the Alcatel comes as standard in IPCop 1.3 and was straight forward to get going. Less than a hour I would say from a clean box to having the network back up. : ) /cb Andrew Sands wrote: List dwellers, Can any wise individuals using IPCop with ADSL indicate the type of modem and/or router they are using and any problems they had getting it set up.

I'd prefer the this is what I have and this is what it took to set it up replies rather than you poor bastard your screwed! :-) If you know what I mean. Also on the other hand, if suggesting to a associate, colleague and/or potential client that they utilise the IPCop firewalling solution what type/model of suitable (for the scumbag Telecom Network) ADSL devices available from a reputable Christchurch sited company can people suggest. This is not my only problem site as I also need to convince the owner of a Ni500 to make the move as well. Anyway, regards all and have a nice happy evening. Andrew
