Re: [SLUG] Federal Gov Open Source Policy
this legislation is meaningless as open source projects cant respond to tenders. vendors are already selling products rooted in, or heavily based on open source. the basis of the softwares development was already irrelevant in the tender process. this legislation should have also included statements requiring software licenses to be strictly adhered to - open source or otherwise - and some commitment to enforcing the disclosure of source code from the vendors when appropriate.

Re: [SLUG] Optus broadband stick
which model is it? this will dictate 3.6 or 7.2 meg max (dual frequency) huawei modems typical appear as two usb serial devices. the first for data, the second provides a control plane of sorts. both use a classic hayes 'AT' like command set, and ppp is used to create an ip connection with the modem. network-manager since about 18 months ago was perfectly able to fully configure and manage usb 3g devices from huawei. google will show you many chat scripts for various ppp helpers if network-manager is not your ice cream flavor. huawei have been very good at keeping a consistent command set so scripts for other huaei models will almost certainly work perfectly if your kernel recognises the device properly. ive found huawei support in linux to be excellent, mostly as a result of using a simple interfacing technique and being consistent.

Re: [SLUG] Which Virtualisation, and why?
Hi David All the linux big boys are moving fast to KVM. Redhat and IBM have abandoned Xen completely, making it an out of kernel patch set maintained by Citrix and perhaps code from Oracle. Youll find that Debian has also elected to discontinue Xen in the next release. Virtualbox is still nice for desktop quasi-trivial virtualisation. (Im sure someone objects to that, and has taken it to a huge scale...) KVM is still the only in kernel hypervisor (if thats what it is, which it sort of isnt). VMware is free as in beer. At my telco of employ, we are using KVM extensively. Im of the opinion is the most sane design, gives you the most control and follows the unix way of re-using existing components to the nth degree. Chances are its already installed on your reasonably recent release distribution of choice.

Centos 4.8 supports virtio for much faster io and network performance. At my undisclosed business we are running 14 physical machines, 128gig ram 2x6 core amd, each with ~100 VMs. Pretty mind boggling stuff.

If your ok with a manual change over with a little downtime (in the case of an intentional transition between servers) I'd put something like ext4 on a LVM ontop of the DRBD partition mainly to keep things fairly simple. to migrate machines you shutdown the guests, unmount the file system on host A, mount it on host B and start the guests there If you want seemless transitions your going to want something like OCFS or somesuch for the file system, which gives you the ability to have it mounted at both locations and hence live migration, you might be able to feed your VM's raw lvm partions on the DRBD system and not bother with OCFS which would make life easier but I haven't looked into that. Upside to this system is you don't have a NAS that can go down as a single point failure. For your offsite backup I'd then snapshot the machines and LVM's and rsync them to your remote location. rsync of the memory snapshot could consume a decent amount of bandwidth, its probably going to be pretty volatile, if you can shutdown the guest snapshot its disk then boot it back up again then the rsync traffic should only be a little over the quantity of changes made to the disk IE files added/changed, so not much more than your existing offsite backup needs. I'm using KVM for my virtuilisation and it seems to be working well, very simple to use and the host has a full OS there to do whatever you want with. Currently I run mysql on the host to get a bit more performance out of the machines (with a ~20Gb database) and the application servers in VM's on the same machine, with mysql replication to pass the data between the hosts.

Customer currently has 3 x HP rackmounted servers runnning Centos 4.8 and a Dell rachmounted server running Windows Server 2003. Backups are currently done to tape every night using Amanda. Given the nature of the business and the reliance it places on computer availability, we're looking at replication and virtualization a a first step and off-site replication of some sort as step two. First thought was to max out the memory on two of the servers, one for normal running and one as a hot or warm standby, and the virtualize all of the servers onto the two machines. An external consultant has already suggested doing this with VMware, installing the ESXi hypervisor on the two main servers and installing a NAS shared between the two systems (hot and cold) so that if the hot server fails, we can simply switch over to the cold server using the images from the NAS. Couple of things concern me about this approach. The first is using VMWare rather than a GPL solution. The second is where we would install the NAS. Physically, the office space is all under one roof but half the building has concrete floors and half has wooden. (The hot server is in the wooden main office, while the cold server was to go in the concrete floor area. There is also a firewall (a real one) in between the two areas). Questions: 1) Can anyone offer any gotcha's, regardless of how obvious they may seem to you? 2) Is there a GPL solution that fit's this scenario? Even if it's not a bare metal hypervisor and needs an O/S. Remember it has to virtuaize both Server 2003 and CentOS 3) What's the minimum connection we would need between the NSA and and the two servers sharing it? 4) What kind of speed/bandwidth should we be looking at for the off-site replication. I'll happily take anything else anyone would like to throw at this - suggestions, reading matter etc - it's not an area of great expertise for us having only paddled around the edges with Virtualbox.

Its also possible that a point 3. might be that distributions are successfully building their own communities, which people are involved in rather than their local linux UG.

Re: [SLUG] Wireless Broadband?
Part of the motivation for buying a modem out-right and use pre-paid is that it doesn't tie us to any plan, plus we expect to use the pre-paid modem very sporadically - in emergencies which happen when the guy on call is out and just must access the network. the down side of pre-paid is that the data expires fairly quickly. a few gigs typically only has a 30 day expiry. larger data blocks tend to last longer (up to 90 days on optus) you can just whip out your credit card and buy a data block. that may not sit well with the on call person... heres a usb 3g modem, just add your CC# and expiry date as needed Dean -- 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] Secondary Mail Server
Ideally, a secondary MX should have the same configuration as the primary. How often does your user list change? It should be reasonably straight forward to provide a list of users to the secondary. If you configure your secondary as a relay host for your primary, then it will accept mail from anywhere and deliver it to the primary when possible. This i believe is the behavior your wanting? Spammers will usually exploit the relaxed rules on a secondary, and the trust relationship with the primary, to deliver spam. My understanding and from observation, is that spammers will try the highest value secondary and work their way down. A normal mail server should do the opposite, trying the lowest MX and working upwards. I have seen recommendations to put your real mail server a few MX's up, and make the rest of the MX's bogus entries, thus (arguably) tarpitting spammers and still allowing proper email delivery - albeit slightly delayed. Keep in mind that if your primary mail server is down, other mail servers wanting to deliver will hold on to the mails and retry for days. So a secondary is not strictly necessary. I must also advocate the use of Exim, it is the best MTA. People may flame away on that point.

Re: [SLUG] IPTables
You most likely want to allow outbound dns and the subsequent reply Keep in mind that blocking outbound usually requires a few more allowances than just the basic service you plan the box to provide. NTP also springs to mind, so that you can keep the clock in sync.

Re: [SLUG] IPTables
Even though dns may not be 'turned on', almost everything tcpip related wants dns look ups. sshd for example, will stall for quite an annoying amount of time trying to do a reverse lookup. unless you dont actually have name servers configured at all. also, not syncing the clock makes date stamps in logs almost entirely unreliable.

Re: [SLUG] attaching lots of disks to PowerEdge 860?
These servers have space for only two internal disks and I'd like to try to convert a couple of them into servers of shared storage. I'm thinking of just setting them up to sync their disks using DRBD and providing access to the rest of the network via iSCSI. I am not sure that you want to use it as an iSCSI host. This is a block level device and isnt really (easily) shared between more than one client system. Most likely you want NFS or CIFS/SMB. External eSATA or USB devices is really the only low low cost option. Using an external iSCSI or ATAoE (or even FCoE) is an option if the disk array is the right price. But then most of them come with an NFS/CIFS head on them anyway. Take a look at Coraid. These guys made up ATAoE and their disk arrays are surprisingly cheap. http://www.coraid.com/ Keep in mind though, it may be cheaper still to just guy a cheap case with lots of disk space (perhaps this behemoth http://www.auspcmarket.com.au/show_product_info.php?input[product_code]=EL-PC-343Binput[category_id]=277 or this much cheaper icute case, of which i have its little brother http://www.mwave.com.au/newAU/mwaveAU/productdetail.asp?SKU=16010594) and then drop in a cheap CPU, a motherboard with a lot of sata connectors and some cheap 4 port sata2 cards.

Future: * monitor web logs on servers for hits, usage, etc. * monitor security related logs on servers. Will it be simpler to use multiple tools, or is there some giant swiss army knife that it's worth learning? What you're trying to achieve broadly falls into two categories: * data collection * notification I find that most of the monitoring tools out there try to do both, and don't quite manage to pull it off. For the data collection, I would recommend using something like collectd[0]. It can collect stats on disk space, io throughput, ups usage, web server usage (apache2 + nginx), vm utilisation, and a whole bunch of other things. It's also network aware, so you can collect stats on all your machines individually, and aggregate the results in one place. For the notification, the easiest option would be Nagios[1]. collectd provides a collectd-nagios[2] binary which can be used to query stats that collectd has collected, and return warnings depending on whether values are out of range (which Nagios will pick up and notify you about). For quick status checks (questions like is mdadm reporting any failures?), you can Google for one that suites your taste, or write a Nagios check yourself to do it. The main advantage of breaking the problem up like this is you can swap out parts of the system when something better comes along. Oh, and for triggering shutdowns from your UPS, try something like Apcupsd[3].

Re: [SLUG] HTTP server recommendations?
Apache is always a great choice. Apache 2 is extremely modular and allows for some mind boggling configuration arrangements. The configuration is somewhat intimidating, but debian has packaged it up to make it much more convenient (and possibly less intimidating). If ubuntu has borrowed this arrangement then the same will be true for ubuntu. Its worth considering that lighttpd, boa etc have significantly less features than apache (how many of these features are in the 80% commonly used 20% rare ratio is of course debatable). So you may find yourself setting up non-apache now, then finding yourself having to convert to apache later, or implement something in an awkward way that apache would do elegantly. I would certainly advocate something like nginx as a load balancer or ssl reverse proxy if the website warranted it.

Re: [SLUG] virtualisation solutions?
Yes, it's Solaris 10. I was under the impression that Virtualbox was focused more on desktop virtualisation and is less geared for servers. Is that incorrect? They are feeling the lure of data center virtualisation. However Virtualbox is probably not mature enough for system critical applications. Xen is pretty powerful, but there is still a lack of good, solid management tools that cover HA, iSCSI integration, replication, migration etc etc. A lack of good management tools is what concerns me. I want to get productive quickly and not have to spend unnecessary time setting up and managing. I don't need zillions of features, but I do want something that's solid and easy to use. Xen is snapping at VMwares heels, however if you want basics and simplicity, why are you resisting the free VMware server. Granted you cant get at all the source code. And i understand the moral high ground. However, from a solution point of view it is free, its the leader of the pack and unless you are in dire need to hack the source of the virtualisation suite xen vs vmware free is largely the same. VMware tools is now FOSS software, and vmware provides API's for its server component which will allow tight integration. Also its guest machines can easily be transported from servers to desktops etc. Im all about open source, and not settling for 'close enough'. But in terms of my 9-5 often times slipping of my moral high ground just a little, goes a long way to keeping my natural hair color :) Dean -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
