Re: [one-users] Infiniband, nodes and VMs
As a first step, I'd like to be able to deploy vms tru IPoIB. The problem ips that my opennebula frontend does Not have infiniband. Only the NAS hosting the datastore mover nfs and the nodes running the vms have IB devices. Is it possible to get opennebula to deploy using the IB network while using ethernet as a managing network?

uppon closer examination, we figured out that the deadlocks were not related to the image problem. I was able to fix the uploading problem using this [1], but the random deadlock issue persists.

Re: [one-users] greetings
Hello! I'm sorry for the delay on my response. Thanks Valentin and Stefan for your responses! You were really REALLY helpful. At the time, I didn't know hooks existed! Even tho it sounds as the more elegant solution, my boss decided we should just route a block of 200 public addresses. Fastest and easiest solution to configure. As we say in Argentina, lo atamo con alambre (meaning, we stitched it with wire cables... there, I fixed it) He also decided I should have no life at all, and assigned me yet more work than I can handle :-D LoL I've got a new 20TB debian storage. Researchers here use the PostgreSQL database, and they have asked me to merge the database service with the cloud. Meaning... they want me to provide the database service from within the cloud. Is that even possible with OpenNebula? One solution I came up with is to install PostgreSQL on the debian storage, then DNAT the storage:PostgreSQLport so it can be accessible tru the firewall... the problem is: I'm limited on the accounting I can do on this service. is there some sort of OpenNebula Plug In that allows ONE to provide infrastructure services other than VMs? For instance: a PostgreSQL engine or DB? Once again, Thank you guys! best regards galimba On Fri, Jun 20, 2014 at 6:57 AM, Stefan Kooman ste...@bit.nl wrote: Quoting Galimba (gali...@gmail.com): Hello everyone. My name is Sebastian.

The problem is that I have a firewall in the middle, managing all the public ips, and my OpenNebula box is on a LAN behind that firewall. Question: Do you want to filter the traffic for your vm's on the firewall in the middle? If the answer is yes than you might want to use the vm-hook like Valentin suggested. If not then a vlan with public IP's is probably the easiest way to go. Another possibility is to use the Public Cloud interface from ONE, specifically: EC2 [1]. It makes use of Elastic IPs. It uses scripting to handle the mapping of public to private ips. Especially the scripts that interact with the OpenFlow seem promising [2]. Yet another way of doing this is to route the block of 100 ip's to a router/firewall (possible running on ONE) (through a little ip interconnection block). In that case you don't have to filter on the firewall in the middle and or do NAT (which I think is very ugly). So like this: public ip - interconnect-ip - router/firwall - router-ip-routed-ips - vm's with public ip. This will also work for IPv6. Natting IPv6 is possible, but even more ugly ;). You still have the possibility to do some filtering on the firewall while leaving the rest of the ports open. If you like GUI's, pfSense is a very nice and capable firewall (based on OpenBSD's pf) [3]. If you would like to use pfSense on KVM - don't use virtio network drivers, broken on KVM (at least that is our experience, intel e1000 works fine).

Is there an easy (and safe) way to assign public ips and pass tru the iptables on the firewall? I mean... the only solution I came up with was to modify the deploy script on the OpenNebula box to connect to the firewall and modify the iptables rules regarding the particular VM I'm trying to deploy. That's not a very happy solution. Thanks in advance. galimba -- ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[GlugCEN] q onda con este bug?
FUENTE: http://arstechnica.com/security/2014/03/critical-crypto-bug-leaves-linux-hundreds-of-apps-open-to-eavesdropping/ Hundreds of open source packages, including the Red Hat, Ubuntu, and Debian distributions of Linux, are susceptible to attacks that circumvent the most widely used technology to prevent eavesdropping on the Internet, thanks to an extremely critical vulnerability in a widely used cryptographic code library. The bug in the GnuTLS library http://www.gnutls.org/ makes it trivial for attackers to bypass secure sockets layer (SSL) and Transport Layer Security (TLS) protections available on websites that depend on the open source package. Initial estimates included in Internet discussions such as this onehttps://groups.google.com/forum/#%21msg/linux.debian.user/NYK3o7u91VI/aIylRShPOGwJindicate that more than 200 different operating systems or applications rely on GnuTLS to implement crucial SSL and TLS operations, but it wouldn't be surprising if the actual number is much higher. Web applications, e-mail programs, and other code that use the library are vulnerable to exploits that allow attackers monitoring connections to silently decode encrypted traffic passing between end users and servers. ___ Glug mailing list Glug@glugcen.dc.uba.ar http://glugcen.dc.uba.ar/cgi-bin/mailman/listinfo/glug
