[SLUG] Switching gnome workspaces with mouse scroll - Ubuntu 9.10
Hi All, I upgraded to Karmic last night but I prefer one panel at the top of my screen so I removed the bottom panel and the workspace switcher in that and added another applet to the top panel. But now I can't switch between the spaces with mouse scrolling, I know the key combo to do this but mouse would be nice as well. Does anyone know how to re-enable this? My research so far hasn't shown up anything other than the bottom applet does it by default and the help files aren't very verbose.

To summarise, you want anyone to login with no password required? (except maybe root) I think the best place to do this is PAM. You could set it so they still need passwords via ssh but not the console gui (gdm/kdm). Actually THAT is easy, this is much harder: UserA logs in (auto or with password) UserB comes along so UserA does logout-switch user UserB logs in to the new session, does their thing and logs out UserA's session is now exposed behind a password dialog. This gives her the sh-one-ts as userB could have done ctrlaltF7 to browse her session before the logout, but now needs to enter her password to access her (UserA)'s original session. This looks exactly like the screensaver password dialog but I cannot find how sessionA is locked when switching to sessionB.

Re: [SLUG] Data Redundancy, RAID5/LVM backup decisions
f its myth, it performs better with your drives as simple partitions. mythvideo will support multiple video directories (check this) mythtv uses storage groups to record and playback with better performance. I set my myth up thusly. 3x 320gb drives (somewhat old, it has had a few 1tb drives added since) all 3 drives are partitioned the same \boot , 200mb raid 1 ext3 \, 10gb raid 5 xfs, you might think about reiser or ext4 for this on 9.10. swap, 1gb raid0 \var\lib\mythtv xfs (pick one drive to do this to) using linux software raid, as a result I have moved this install through a few systems. I leave the rest of the space empty during install then i partition the remaining space on each drive as xfs (good for large files) i mount those partitions as /var/lib/mythpool/1 /var/lib/mythpool/2 mkdir /var/lib/mythpool/1/recordings mkdir /var/lib/mythpool/1/video etc then go into myth and edit the storage groups to add /var/lib/mythpool/1/recordings to the general recordings pool and the same for video. if you want to add another drive you just stick it in, partition it and tell myth about it. stick videos on whichever drive has the most free space at the time. Mike Andy wrote: Ok so i'm trying to figure out what to do with all my data when I upgrade and i've got more options and ideas than i know what to do with. At the moment I'm on an everything machine I'm considering breaking it up into two different machines. All this might be aside from the overall point but basically my desktop is my MythTV backend, MythTV frontend, a samba server, virtual box/vmware player, and general desktop. If i go ahead with splitting it up i'll probably put centOS or debian on the server and have it running Samba and MythTV backend. I'll get a bunch of WOL and ping/sleep idle scripts like i've already got running to and from the server to save power. MythTV and Samba shares are going from my desktop to another frontend hooked up to a TV downstairs for good times. on my desktop I've got 2 hard drives totalling a possible 2TB in LVM folders on my desktop of ripped DVDs and CDs etc.. My /videos folder is larger than a single hard drive it's self, that and the fact that I was on a budget is why i chose LVM. The 3rd hard drive is 300Gig and is not in LVM and is my OS hard drive (Arch Linux, Ubuntu, XP) So I'm recently getting more and more nervous about my OS hard drive crashing, and to a lesser extent one of the media drives crashing. So what should I do? At present I use clonezilla to backup my Arch OS to a spare partition (along with standard photo/document backups done) Could i get my OS hard drive and put it into RAID5? if so, how? I'm confused because I heard I can do RAID5 in software, though i don't understand how that would work or how to get it running across 3 or more different operating systems. I heard RAID is also something a motherboard can control too, actually i know nothing about RAID! Also is it possible to get LVM working inside a RAID5? I could do that for my data maybe? Sorry i'm a bit of a noob but i'm keen on learning, unfortunately i'm self taught so go easy on me! -- 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] Pulse Audio
2009/11/2 Daniel Pittman dan...@rimspace.net Heh. Let me assure you, the integration question wasn't FUD: it is firmly grounded in fact. Well, at least, was, in the sense that the first Ubuntu with PulseAudio *really* screwed up. [deleted long description of what I may have been through myself too, without knowing all the details Daniel explains] I'd just like to point out that after a long time with 9.04 and no mic working (essential for Skype calls) - once I upgraded to 9.10 and found some ubuntu wiki page which explains what to look for I got mic working with very little GUI twiddling. Sound output was already on with 9.04 (after initial period of it getting lost after a while). So now I have Skype working properly with both the stand-alone mic and the one on the webcam. Ubuntu 9.10 warned me very clearly about some SMART errors on the office desktop disk (I took the opportunity to replace the disk by two disks and an MD mirror raid :). I don't follow this stuff closely but my general impression is that Ubuntu's weak point for a while now is not enough integration and testing - for many things not just PA.

[SLUG] Asset Tracking / Inventory Management
SLUG, Looking for a lightweight open-source asset tracking / inventory management tool. Our needs are basic, but we may want to customize the model or starting getting funky with it. The tool should: - Have a reasonable web based interface - Allow us access to the data raw or otherwise leverage it for our automated tools (monitoring, configuration management) - Allow us to customize the model Basically we want to store the information about a number of xen guests and their hosts, and some network related information in a database where we can all access it. Any suggestions? A simple rails/django app you have used would be sufficient.

Re: [SLUG] advice on security compliance
2009/11/2 Daniel Bush dlb.id...@gmail.com: I was following Rick's recent post about penetration testing with some interest. I'm looking at complying with anz e-gate for e-commerce transactions. ANZ has this declaration form for internet sites that you have to sign. One of the tick boxes says Do you operate a firewall that is regularly updated? I'm a bit late in the party but still wanted to add my two cents if that's OK. Some relevant points I learned during the PCI DSS compliance process we've gone through: 1. They also care not just about preventing people getting unauthorised access to your server but also in making it difficult to get data out (e.g. by someone with an inside knowledge). So firewall rules should also limit outgoing connections to specific hosts. E.g. you want to talk to specific, hopefully more trusted, DNS and NTP servers, specific upstream SMTP servers (instead of allowing access to just about any SMTP server in the world) and maybe specific yum update servers, but not more. Since rules could be added to allow you temporary access outside for specific tasks, it might be prudent to verify once in a while that they are back to the way you expect them to be. 2. Application firewalls can add a lot to the simple block everything except ports 80 and 443 iptables. I'm talking about mod_security and having its rules updated regularly to catch attempts to exploit holes in known application as they get discovered (e.g. http://www.gotroot.com/tiki-index.php?page=mod_security+rules). 3. They care about auditing and accountability - the rule of thumb is no shared accounts - if there are more than one users on the system then each should use their own account and sudo ... for each privileged command. It also makes it easier to track who did what and when (bash HISTTIMEFORMAT='%F %T ' is also very useful, not just for Them). 4. SE Linux is a major headache, I seem to be in the mainstream by disabling it for now. But it appears that once you get to learn it and tweak it properly it can add a lot to the security on your server and limit the damage done by a potential cracker. e.g. allow HTTP access to the yum servers only by the yum process, or send mail only from specific programs/scripts. The best tutorial I found about SE Linux so far resides in http://docs.fedoraproject.org/selinux-user-guide/f10/en-US/ (I still have to finish reading it) In general - you can look at this as ah yeh, the security lawyers and paper pushers are at it again but I found that giving attention to these requirements and the thinking behind them makes a lot of security sense (most times - anti-virus for purely linux environment is pretty useless from what I've researched so far) and should end up in more secure servers.
