find(1), which is used to locate a list of files matching a given set of

The guide to securing bind9 available from the SANS link I posted has a
good template for configuring your system to act safely, even if you use
a single system as a resolver *and* an authoritative DNS server.
I used it, (urgently since my systems were participating) and it has
resolved the issue: rimspace.net no longer responds inappropriately to
outside queries, but is a recursive and authoritative resolver.
I highly recommend their guides.
yeah I have been through it, had it mostly configured that way - but
nothing majour missing.
I was more sort of interested to see if other members were seeing it,

It is pretty trivial to get a standard AHCI SATA controller for six drives, although 8 are less common. A 4 port AHCI PCIe SATA controller is fairly inexpensive though... I would recommend amd 5200+ gigabyte ma78gm-s2h+2gb from fluidtek.com.au, 5 sata and a Adaptec 1430SA SATA II RAID Controller - 4 Port $199 from techbuy. I put this together in a tower case with 4G of ram, with 9 x 1T drives ($150 / drive fluidtek). works really well with debian amd etch ( and above). The one caveat is you have to compile your own nic driver the one in the kernel doesn't support the one on the motherboard. or ga-m750sli-ds4 (6 sata) again with the adaptec card (works out the box). For a total of 10 x 1Tb (raid6). had some problems with optical out with this mb, because it was so new, but 1.0.18 fixed that. both have gige nics Alex (recent buys in the last 12 months) Now for the but: The NAS devices are generally less power hungry, and sometimes less noisy, than building your own NAS solution. They also (generally) come with hot-swap disks rather than fixed. Building a PC that has hot-swap will generally cost you more than buying the NAS. Finally, the NAS kit usually performs less well than the PC, which matters for high IOPS or streaming workloads, but hardly at all for normal use. (Notably: you see somewhere between 1/4 and 1/10th the performance with the NAS device compared to local SATA with RAID, depending on the sort of testing being done.) Personally, I ended up with a server with hot-swap SATA, and am happy with that — but I a new server anyhow, and it cost less than buying a new server /and/ NAS storage. Once it fills up (6 SATA disks, possibly 8 if I get enthusiastic) my plan is to start a collection of the NSS4000 units. They run nothing but Linux, are *fully* source-available, and should be able to be upgraded to a real distribution if I wanted... They also do ATAoE, so I can mount their disks via a back-end gigabit network and talk to them directly as high latency local disk in my server, allowing me to manage them nicely without having to buy an NSS6000 and live with their built-in limits... (Plus, I prefer to have a sensible server doing access control, etc, rather than trusting an appliance to do it — it reduces the number of places I have to worry about problems cropping up.) Does that help, or just confuse things more? Feel free to ask if you have more questions about any particular part of my writeup.

Having a look at the ip-up scripts there is no mention of user id. I have noticed that pptpd logs to wtmp logins and logout. I was figuring that i could use the ip-up scripts to capture the ip address of the client, find the interface and then lookup last to find the user and then I could set some iptables rules. and then try and undo what i have done on logout. But that seems fraught with too many places it could go wrong. I don't really want to undo the winbind install and move to radius (seems like more pain that it would be worth) It would be nice if I could use the chap-secrets and winbind as the same time, but that seems to be ruled out by the winbind plugin. any thoughts ?

Re: [SLUG] Capturing emails from IMAP folders
On Mon, Oct 13, 2008 at 06:56:41PM +1100, Nigel Allen wrote: Hi We are currently modifying an email system for a customer and have got a little stumped at their latest request. Basically what happens now (paraphrasing) is that a customer service rep receives an email from a customer. We have put a plugin into Thunderbird that, when the send button is pressed, prompts the rep for a customer number. That number is embedded into an X-header in the email. At this point on the linux server, mimedefang looks into the email and if it finds a header, it validates the customer code that has been entered. If it is a valid customer number, mimedefang writes a copy to customers (a large email account with hundreds of folders). When the copy arrives in customers, procmail grabs the header value and files away the email into the correct subfolder. The problem is that the original email is still sitting in the rep's inbox. What the customer has asked for now is for something that will grab the original email from the rep's inbox and file that in the correct place with the response automagically. The only identifier which is common across the emails that I can think of using would be the in-reply-to header. Does anyone have any thoughts of how on earth we could comb through the user's inbox in real-time and achieve this? not sure if it will do all of it, but grepmail might be a place to start TIA Nigel -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- Any reproduction or redistribution of the Software not in accordance with the License Agreement is expressly prohibited by law, and may result in severe civil and criminal penalties. signature.asc Description: Digital signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Re: [SLUG] Multiple Offices with redundant DSL Connection

You have to decide on your networking policy, is it going to shared, load balance, fail over. You could also look at setting up a tun device sitting on top of openvpn and try and aggregate the lines - but very complex setup. I would suggest to keep it simple if you have 3 offices A, B C.and 2 connections at each site (same spec) 1 2 then something like this (forgetting about DMZ's, presuming its all private traffic) A2 - B1 B2 - C1 C2 - A1 These can be the primary paths - this is simple to do with weight/metric is the routing table and then the failback (backup routes) A1 - B2 B1 - C2 C1 - A2 you could have 2 instances of openvpn running at the same time and again you will need to setup routing with weights/metrics so on A you would have something link (private LAN) ip r a B/24 via openvpn primary interface addr metric 5 ip r a B/24 via openvpn secondary interface addr metric 10 this way primary route would be used until it is not available. NOTE this doesn't do any load balancing, so you don't get the benefit of 2 lines. as for userid's, is this for vpn login, workstation login ? What is the predominant OS used in the company, probably stick with that. I am not sure if you can link AD and/or ldap into openvpn with cert's and userid password.

Sorry my presumption that this was a norm of some sort. I have a dns server that host a public/internet facing domain. only lan clients can make recursive requests. eg, is it set up to allow normal DNS queries to only a certain range of client IPs? or is it a private DNS server that's authoritative for an internal domain that you don't want people external to query? This could be as simple as someone's laptop set to use your DNS server and they go home and are suddenly coming from an external IP but still using your DNS server, so any normal DNS queries are being sent to you first (eg, www.google.com) nope = well not set by me atleast The log itself looks like it's just after an ordinary A record.. If your sure it's an attack it could be someone trying to find names in your zone by trying a whole bunch of names a'la brute force, but that's pretty but they are not requesting anything in my domain ? unlikely imho.. by doing that they might be interested in finding internal IP ranges so they can play NAT tricks for firewall rule enumeration or perhaps finding the IP of certain functional servers, eg names that indicate what kind of network service an IP may be providing - eg, samba.example.comor printserver.example.com - something that gives them a new attack vector.. You could also be participating in a DDoS - because DNS is UDP, forged source IPs can be used to start sending DNS replies from a whole bunch of DNS servers to a target IP, thus using all the targets bandwidth Just in case I drop their address at the firewall now :) (only 2 - somewhere in china) On Wed, Jun 25, 2008 at 3:28 AM, Alex Samad [EMAIL PROTECTED] wrote: Hi I have been seeing these in my logs Jun 25 15:19:45 hufpuf named[3574]: client 59.151.50.248#64821: query (cache) './A/IN' denied Jun 25 15:19:48 hufpuf named[3574]: client 59.151.50.247#63595: query (cache) './A/IN' denied Jun 25 15:20:25 hufpuf named[3574]: client 59.151.50.248#10848: query (cache) './A/IN' denied Jun 25 15:20:28 hufpuf named[3574]: client 59.151.50.247#9753: query (cache) './A/IN' denied I can understand 1 / day or maybe / hour, but I have a couple of pages full in side an hour. can somebody shed some light on what they think they can gain ? -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFIYgG9kZz88chpJ2MRAklTAJ9EglbfqgbT4zr9KBH2FUD9e6Ld3wCg7QVP Mh+7tVHJ4dLSPTS4LxvTs0c= =Pe1p -END PGP SIGNATURE- -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- See, the irony is that what they need to do is get Syria to get Hezbollah to stop doing this shit, and it's over. - George W.

Hi there,
Thank you for your e-mail.
I have checked my mixer settings in Ubuntu and the sliders for PCM Centre,

ummm no dmix in alsa, do a google for dmix alsa

this is a fragment of my /etc/asound.conf, notice the bindings option
please also reply to the list, that way other people can get help with
this as well.
I have been reading that will Pulse audio you can not get 5.1 channel
sound but would rather check it with the people in the know.
Hope you can still help me.

And how does it work when the VPN is NOT connected? Is it smart enough
to figure out not to try 10.2.2.{1,41} when the VPN is down and go
directly to the external DNS?
Basically, yes. It obviously won't resolve internal fqdns because they are
not reachable anyway, neither are the internal dns servers, but the resolver
still tries the localhost dns server first (as it is the first nameserver in
the /etc/resolv.conf file) to resolve an external address and the forward
first clause causes the localhost dns server to try the (now inaccessible)
forwarders just the once and then give up, and the resolver then goes on to
try the other dhcp supplied name servers. Thus there is a small delay in dns
resolution but I don't see it as a major problem. I guess if you used the
forward only clause then it might knicker up.
I was hoping for something more along the lines of when the VPN link
goes down - reconfigure:
1. Remove the search soho.lannet.com.au line from resolv.conf
2. Reconfigure local DNS server to forget about the zone
soho.lannaet.com.au part.
why not have 2 resolv.conf something like resolv.conf.{a,b}, then
symlink to resolv.conf.
attach a script on vpn up to symlink .a and when the vpn is down to
symlink .b

I'm sure it's doable. Will try to get to it over the weekend (need to
be outside the office to test this).
Maybe it's less relevant to you because you still want to use the same
name but get the external view when the VPN is disconnected, right?

This is not quite true. Data can be exported from the clinical component of HCN's software, Medial Director, on a patient by patient basis. One output option is XML format. I offer a modest example, http://ozdoc.mine.nu/wedgetail/wedetail_wedgewood.xml The format for this data is undocumented but should not be too difficult to decipher. It changes from time to time so you are playing samba to HCN's Microsoft. Nevertheless if we can get a stable data structure for clinical information, it becomes much more feasible to move clinical between rival Australian EMRs (electronic medical record systems). This is the path as Tony and Ken suggest and is certainly the next step. Another hoped for, and perhaps more stable, format will be that of Google Health's. This is in beta and they are making the API available for external developers. Now, this type of software is the perfect candidate to be on an open platform (which some medical practices use Linux to store a flat-file database on), and with simple google seaches I've found some open-source Medical Billing/Appointment book practice management suites, but they were all on 0.x releases and unsuitable for the Australian medical billing system, with no mention to Medicare. Has anyone found anything for Australia; I'd be interested in following the development for a Linux/multiplatform open-source practice management suite suited to Australia's medical/Medicare standards.

Idle speculation is no match for the man: rsync -avz foo:src/bar /data/tmp This would recursively transfer all files from the directory src/bar on the machine foo into the /data/tmp/bar directory on the local machine. The files are transferred in archive mode, which ensures that sym- bolic links, devices, attributes, permissions, ownerships, etc. are preserved in the transfer. Additionally, compression will be used to reduce the size of data portions of the transfer. rsync -avz foo:src/bar/ /data/tmp A trailing slash on the source changes this behavior to avoid creating an additional directory level at the destination. You can think of a trailing / on a source as meaning copy the contents of this directory as opposed to copy the directory by name, but in both cases the attributes of the containing directory are transferred to the contain- ing directory on the destination. In other words, each of the follow- ing commands copies the files in the same way, including their setting of the attributes of /dest/foo: rsync -av /src/foo /dest rsync -av /src/foo/ /dest/foo (with out actually testing, just relying on memory and speculation :)) ) the first example you would end up with /dest/foo the second you would end up with /dest/(and the children of foo) Looks like JW was correct. cheers rickw -- _ Rick Welykochy || Praxis Services Tis the dream of each programmer before his life is done, To write three lines of APL and make the damn thing run. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- Expansion means complexity; and complexity decay. signature.asc Description: Digital signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

I want this mail address to take the mail as spam and then processes into the userid spamassassin's spamassassin DB I run 3 accounts (not) called amspam amnot maybe I am presuming this is are not different email;s and by bouncing you are not talking about using smtp to move between accounts All spam that is received is *bounced* to amspam Everything tagged as spam gets sent to maybe Not Spam in maybe gets bounced to amnot cron.daily runs a 'bayesian' task to learn amspam and amnot Bouncing is different for each mail client.

Please confirm that the above is correct, or point out any errors if applicable. After lots of Web searching I've spent hours recently changing UUID's and disk/partition labels due to moving HDs from another PC ( I currently have 3 IDE and 2 SATA HD's plus a DVDRW in this PC) and don't want to stuff this up.

[SLUG] Setting up a spam email
Hi I want to set up an email address where for my domain, were users can send spam emails to and they will be added to the spam DB. I use debian, exim and spamassassin. All my spam processing gets done as user spamassassin, so I thought I could just process all mails sent to spamassassin as spam with a procmail rule like # # Record it as spam :0 fw | /usr/bin/sa-learn --spam but then I realised how do I get it to ignore the senders address (because it will be one of my addresses and I don't when then blacklisted ?) how do other people setup site wide spam addresses Alex -- I also understand how tender the free enterprise system can be. - George W.

Hi I was wondering if any one has any recommendation for some interactive kids programmes for learning/playing that i can get for linux. I currently have a spare keyboard that the little bashes on, but I would like to have something happen on the screen as well and hopefully maybe learn some things as well?

Re: [SLUG] bigpond cable modem and any old DHCP client?

Specifically, is it possible to use the SB-5101 modem and plug in a DHCP-client wireless router on the ethernet side, or does BigPond still require a custom login tool running on the client? I have a cable modem and a normal linux box running just dhcpd (with out the old bigpond login client), but you need to be on the new billing system The whirlpool forums are fuzzy at best, and I'd like to know if anyone can give a definitive yes that will work versus no, that won't. Why? It might be cheaper to use an existing wireless router, or easier to maintain a linux PC as a router, than purchase the all-in-one SBG-900 cable modem + wireless router with a new plan.
