Re: Fwd: [SLUG] SLUG meeting videos/slides? SYSADMINS:- LOOK AT VIDEO STORAGE
Yes, I had the same issue. I actually found that Movie Player (totem) actually does a better job in playing then mplayer. (mplayer basically shows garbage/blocks, whereas totem just does a freeze-frame for a second or two when the errors occur). My guess is that during the transfer from camera to disk (maybe using dvgrab??) that video frames are being dropped - possibly due to your capture workstation not keeping up with the firewire/1394 transfer. The fault-mode displayed doesn't seem to what you would normally see because of an encoding issue, but I could be wrong.

[SLUG] Any knowledgeable bacula users on the list?
I've been battling with some issues with our install of 1.38 (etch, stable release) and I cannot seem to get the backups back on track. Rather than submit the list to the rather long problem and ensuing configs I figure I'd ask first. Essentially the problem is that bacula appears to have lost track of it's volume retentions and is using volumes (both tape and file) all over the place instead of linearly. Amongst things I've tried re-initialising the MySQL tables to get it back to a fresh slate, but with no luck. If anyone can assist it'd be appreciated. I'm happy to post config files and errors as required.

Oh. This is a VE inside a Virtuozzo system? (The commercial version of OpenVZ, specifically, and a "containers" solution.) Your ISP response isn't terribly technically accurate, then. (I should have noted that from the specific kernel version. Tsk.) Inside the VE you can't load kernel modules, and they shouldn't have bothered putting a kernel image on disk — the kernel is not accessible to you, which is also why lsmod returns nothing. > Seems that there is only one kernel running that is shared by all the > virtual machines, not sure of the details but bottom line is, no > kernel modules! Well, not that are accessible to you. However, two options: http://wiki.openvz.org/VPN_using_IPsec http://perso.telecom-paristech.fr/~beyssac/pipsec/ I would take the second option, since it seems that vpnc has some issues with the Juniper VPN implementation. If the ISP can provide a TUN interface, which isn't a security risk to them and is virtualized, as well as routing for the traffic types needed[1], then pipsecd should work just fine. Regards, Daniel Footnotes: [1] Which is probably the less likely option, sadly, unless your friend paid for a dedicated IP for his system. -- 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] Site to Site VPN
That isn't right! The RHEL kernel should have a whole bunch of modules, and their being missing is not a good sign. [snip] ...because your kernel is screwed. Try reinstalling that to get all the modules in place, then give IPSec a shot again. :) The thick plottens! The box that I'm trying to make be the VPN peer is a Virtual machine which is running Virtuoso and it's kernel has been deliberately "screwed" to prevent kernel modules from being installed because "they represent a security threat to the other VMs" at the ISP. Seems that there is only one kernel running that is shared by all the virtual machines, not sure of the details but bottom line is, no kernel modules! So my mate will now have to consider his options and will probably have to move to a dedicated server environment. In the mean time I'm going to try and set a VPN up from another test box with a real kernel that does support modules. Ah who'd give away computing for a life in the Bahamas? ;-) Pete -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

OpenSWAN used to provide the in-kernel parts; now they provide as ISAKMP daemon and management tools, as do a bunch of other people.

Re: [SLUG] Site to Site VPN
Hi Daniel, thanks again for the info re the routing tools setting the preferred source address. >Wait until after you get ISAKMP and IPSec routing working, /then/ say it is the wrong tool. ;) LOL, yes I meant it was "the wrong tool to talk to a Juniper Netscreen". And as I'm rapidly finding out getting the IPSEC to just load and run is a battle. I'm wondering if IPSec is supported by this centOS version with kernel 2.6.18-028stab060.8 #1 SMP The /lib/modules directory is empty and lsmod returns no modules loaded in the kernel. I've read up a bit and it seems that openswan is not required? Apparently you install ipsec-tools, edit say ifcfg-ipsec0 in /etc/sysconfig/network-scripts and then run ifup ipsec0 But when I do so I get this error message ERROR: libipsec failed pfkey open (Address family not supported by protocol) racoon: something error happened while pfkey initializing. If I try to do a modprobe then I get: FATAL: Could not load /lib/modules/2.6.18-028stab060.8/modules.dep: No such file or directory Hmmm, might be a long road ahead, sigh Cheers Pete -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Wait until after you get ISAKMP and IPSec routing working, /then/ say it is the wrong tool. ;) More seriously, it isn't the tool for this job, because Juniper use IPSec, but it is a good general VPN solution where you control both ends of the deployment, or have a cooperative remote.

Re: [SLUG] Site to Site VPN
Hey Daniel, Thanks for the info, that's helped to clear things up. I think I've got a reasonable shot at making this work. Will look into the idea of assigning a secondary address to the VPN link and setting it as the preferred source IP. That makes sense and is probably cleaner than setting up a source nat, I just didn't know that the VPN software could do that. Darn clever these linux guys. Also searched and found some more info on openVpn vs IPSEC and yes agree entirely, openVPN uses a different protocol and is the wrong tool.
