    Firewall for managment network

    Ok, an ugly work around: INPUT ACCEPT OUTPUT ACCEPT Build an 'Security group' in the datacenter which OUTPUT DROP all essential destination ports like 20,21,22,23,80,161,443,3306,5432,8006 ... Then add this group in the firewall of the VM.

    Firewall for managment network

    Hi, our VMs always have a managment network interface. Now we had the problem that a person from outside needed root access via ssh to do some work. We thought it is possible to block everything from the VM to our managment net, but still allow ssh from the managment net to the VM. But... we...

    External CEPH performance and more ...

    Hi, maybe I'm 'naive', but I have to copy files inside my CTs and VMs. And if this is so much slower, even in a container (which is not the case when I use a local disk at the Proxmox server as storage), than I have 2 possibilities: 1. Using 'real' servers and CEPH 2. Using Proxmox and use...

    External CEPH performance and more ...

    Hi, my rates are given in bits per second. How I did my tests: Very simple but like in daily use, I always used mc in a Debian 8 environment. Proxmox 4.4 is also a Debian 8, so the 'outer' environment is/was always the same. I copied an ISO file of 6GB. No cache has such a size. Since I...

    External CEPH performance and more ...

    No, if you read a bit below, you can see that I was able to achieve nearly the same speed when I mount the CEPHfs on the Proxmox server by hand and start a file copy in the mounted directory. The speed of >5000Mb/s is available. But not inside of a CT or VM :( Btw. sync on a CEPH cluster ???

    External CEPH performance and more ...

    Hi, we just installed a separate CEPH cluster with Debian 8 and Kraken (because up to now stretch is not officialy supported by CEPH) The cluster works and everything is connected via 10Gb network. A first filecopy test on one of the OSDs itself resulted in 6500Mb/s. Fantastic. Then we...
