Hi, in port knocking setups, it would be great to have the possibility to execute a shell command before the ssh connection is actually initiated. That way, one could configure ssh like host foo hostname foo.bar.example user baz pre-connect knock foo.bar.example 1234 5678 and transparently initiate the connection by saying ssh foo. ssh would then first invoke the knock process and then initiate

Hi, I have dovecot 1.0rc15 on Debian and would like to allow plaintext auth not only from the local IP address but from the entire local network, but not from everywhere. Is that configurable? I am looking for something like "allow_plaintext_auth = 10.8.0.0/24". Greetings Marc -- ----------------------------------------------------------------------------- Marc Haber |

Hi, I would like to be able to configure VMs running off dm-crypt devices that were unlocked in the host. Unlocked dm-crypt devices show up in /dev/mapper/devicename, with devicename being the second parameter given to cryptsetup luksOpen. The LVM storage pool type insists on searching in /dev/vgname and cannot be tricked into reading /dev/mapper by giving it a fake VG named mapper; the LVM

Hi, I have virt-manager 0.9 connecting to a libvirtd 0.9.3 on Debian unstable. Hypervisor being used is KVM. In a VM, I can select the "IDE CDROM 1" and click on "disonnect" which makes the virtual disk disappear from the virtual drive and the former disconnect button now reads "connect". Hence, when I click there, nothing happens. Currently, the only way I am

Hi, for a test lab, I'm trying to write a small shell script that will eradicate all information regarding a special host from the known_hosts file. Unfortunately, it is quite non-trivial to find out what ssh doesn't like with a host. ssh says which line in known_hosts has the offending key, but ssh-keygen -R doesn't take a line number. Am I using an undocumented interface when I

Hi, my test host is running Debian/GNU Linux unstable and has virt-manger 0.9.5 and libvirt 1.2.1. I am using encryption and thus have devices in /dev/mapper that are not LVs, for example called /dev/mapper/myvirtualdisk. I'd like to configure libvirt in a way that allows me to directly assign such devices to a VM. This does not work when I create a filesystem directory storage pool in

Hello, I currently have an "interesting" task to accomplish: An IT environment with about 90 % Windows and 10 % Linux machines would like to unify backup. Currently, the Windows world backs itself up to tape using Backup Exec; the Linux world has Amanda backing up to a big disk RAID. This RAID is acting up and is scheduled to disappear. The current plan is to back up the Linux world

Hi, I would like to use btrfs subvolumes as storage place for VM images to use snapshots. Unfortunately, this does not seem to work in virt-manager at least since the "filesystem directory" storage pool type does not allow me to descend into subdirectories. Is there a trick to do this? Can I do it with virsh, or in the XML? Greetings Marc --

Hi, I am virtualizing with KVM via libvirt and virt-manager. To have decent amounts of Entropy in the guest, I tried loading virtio_rng in a running VM. Despite the module being loaded, I didn't get any log entries, and also no /dev/hwrng. Do I need to enable the virtualized random generator in libvirt/virt-manager? If so, how do I do that? Is the support for this rather recent feature

Hi, I am trying to access my Galaxy Tab from Samsung KIES running on Windows 7 inside a KVM VM. This unfortunately does not seem to work as expected. My Distribution is debian unstable. I therefore have qemu-system-x86 version 1.4.0+dfsg-1exp, libvirt 1.0.3-1 and virt-manager 0.9.4-2. lsusb shows the Tab as follows: Bus 001 Device 016: ID 04e8:6877 Samsung Electronics Co., Ltd Galaxy S in

Hi, I have a virtualization host running KVM and libvirt 0.9.12 (on Debian unstable). I would like to connect with virt-viewer 0.5.4 from a different host to a domain that has Display Spice configured as graphics interface. I can connect to the KVM host using virsh --connect=qemu+ssh://mh at fan.local/system and start m KVM domain from there, so I guess that authentication is just fine.

Hello, after two decades without a dedicated file server at home, it is about time to have Samba. While I am mainly a Linux guy there is a couple of systems that don't find rsync and sshfd adequate. We do have a handfull of standalone Windows 10 machines, a bunch of smartphones and a zoo of home entertainment appliances such as a TV, Sat receivers, IP radios/audio players. In addition to

Hi, I am using rsync to keep two directores on two servers in sync. Machine A, the "client" is the one where the rsync process is invoked, which then logs into Machine B, the "server" as root with ssh and a key. The key is restricted in /root/.ssh/authorized_keys to a script that checks wither $SSH_ORIGINAL_COMMAND matches the rsync --server command that I expect, such as, for

Hi, I would like to run a network firewall as a VM on a KVM host. There are ~ 25 VLANs delivered to the KVM host on three dedicated links, no LACP or other things. I have the VLANs 100-180 on the host's enp1s0, the VLANs 200-280 on the host's enp2s0 and the VLANs 300-380 on the host's enp3s0. To save myself from configuring all VLANs on the KVM host, I'd like to hand the entire

Hi, Exim4 is running fine and I am trying to set up Dovecot 0.99 to handle virtual users (http://wiki.dovecot.org/moin.cgi/VirtualhostingWithExim) so I don't have to set up user accounts for each e-mail address I want to server out via pop3. I need to create a user and passd file, a bit like /etc/passwd, but in a different location for my dovecot virtual users. I can create a blank file

Hi list I am just experimenting with seting up my own email server. I want some tips and hints on how to secure my setup to prevent unauthorised assess to my email. I have read through the wiki and have not found many tips. I hope to improve the wiki with tips gathered from the emailing list. :-) A basic measurement I could take right now would be to set more secure file premissions on my
