The default value if qemu.conf options chardev_tls_x509_verify,migrate_tls_x509_verify, or backup_tls_x509_verify are not specifiedexplicitly in the config file and also the default_tls_x509_verify configoption is missing are now '1'. This ensures that only legitimate clientsaccess servers, which don't have any additional form of authentication.
Libvirt now provides a virt-ssh-helper binary on the serverside. The libvirt remote client will use this binary for settingup an SSH tunnelled connection to hosts. If not present, it willtransparently fallback to the traditional nc tunnel. The newbinary makes it possible for libvirt to transparently connectacross hosts even if libvirt is built with a different installationprefix on the client vs server. It also enables remote access tothe unprivileged per-user libvirt daemons (e.g. using a URI such asqemu+ssh://hostname/session). The only requirement is thatvirt-ssh-helper is present in $PATH of the remote host.

After renewing TLS certificates, it was usually necessary to restartlibvirtd for the new ones to be loaded: now the same result can be obtainedwithout restarting the daemon by using virt-admin server-update-tls .
PCI support for RISC-V guests was already available in libvirt 5.1.0, butit required the user to opt-in by manually assigning PCI addresses: withthis release, RISC-V guests will use PCI automatically when running againsta recent enough (4.0.0+) QEMU release.
The requirement resulting from private chains improvement done inv5.1.0 was refined so that only tables from corresponding IP versionare required. This means that if a network doesn't have IPv6 enabledthen those tables are not required.
While it's reasonable to turn off client certificate validation, as settingit up can be non-trivial, clients should always verify the servercertificate to avoid MITM attacks. However, libvirt was using the same knobto control both checks, leading to CVE-2017-1000256 / LSN-2017-0002.
Download the ISO image and burn it to CD-ROM or Install from USB Stick and boot your server from CD-ROM or USB stick. For a quick how-to see Quick installation or check out the detailed Installation article.
If you run windows KVM guests your operating system will recognize some hardware changes on the first boot and windows shows a new network card in the device manager. (e.g. you need to reassign the fixed IP setup to the new network card. if you have DHCP setup there should be no issues). Under some circumstances reactivation of your windows license can be necessary.
Variant ThinClient contains applications supporting most popular connectivity protocols like: Citrix, RDP, NX, Spice, VNC and SSH. Our goal is to deliver an operating system which works as a client for your existing shared/virtualized desktop infrastructure. Thin client model improves the security, simplifies the maintenance and allows to reduce hardware costs and energy consumption as all desktop applications are hosted on the server side.
Please find below an overview of new features which can be controlled through the kiosk wizard or through the remote kiosk config in upcoming Porteus Kiosk version 4.1.0.1) Kiosk config can be hosted directly on Porteus Kiosk Server variant "Premuim". In order to take advantage of this feature the clients must be configured with 'server://config_name' protocol. Feature can be controlled in the remote config by following parameter: kiosk_config.
You can now protect the kiosk or server session with a password. Only authorized users can access the browser/administration panel and use the system. Feature can be controlled in the remote config by following parameter: session_password.
Here is our usual overview of new features which can be controlled through the kiosk wizard or through the remote kiosk config in upcoming Porteus Kiosk version 3.6.0.Implemented support for Porteus Kiosk Server which allows monitoring, accessing and managing the clients even if they are placed behind a NAT, proxy or firewall. Feature can be controlled in the remote config by following parameters: kiosk_server, client_id.
If you want to become a beta tester then please install the server ISO in a network location accessible by the kiosk clients. Next step is to install standard 3.6.0_Beta ISO and activate 'Porteus Kiosk Server' option in the wizard to associate clients with the server:
Once server and clients are up and running then SSL tunnel is created between them to allow communication throug the SSH and VNC protocols (which are embedded in the SSL). Our goal is to access the kiosks even if they are placed behind the NAT, proxy or firewall.
Instead of using our default 'Ripples' screensaver its possible to use images slideshow. JPEG and PNG images should be packed into ZIP archive (other archives are supported) which must be kept on your server all the time as it will be downloaded during each kiosk boot:
Kiosk Wizard allows appending specific string to the homepage. It can be either MAC address or the hostname. String will appear only in the server logs and wont modify the homepage URL. This is useful for kiosks tracking purposes.
We understand that corporate environments are very often locked and restricted so thinking how to handle the server (kiosk management unit) and the client (kiosk PC) communication in the less problematic way. Probably some VPN or SSL tunneling will be required to avoid NAT/proxy/firewall issues. Need to investigate this further.
Another advantage is that the kiosk becomes automatically safer as devices and their nodes are removed completely from the system. Even after successful ssh password breakage (if someone enabled ssh server in the kiosk wizard) an attacker wont be able to wipe our hard drive with 'cat /dev/zero > /dev/sda' command as /dev/sda node does not exist anymore.
The other problem was a proxy authentication which very often is required in restricted/corporate environments and was not implemented in the kiosk so far. I have found that wget utility (which we use in kiosk to download full wizard, additional modules and updates from our server) is able to perform a proxy authentication with the 'basic' method (but not digest, NTLM, SPIEGO, etc) so proxy authentication support has been added to the welcome wizard. If your proxy requires authentication then please enter the data in following format: USERNAME:PASSWORD@IPADDRESS:PORT.
Correspondence between the project root folder, the folder on the server to copy the data from the project root folder to, and the URL address to access the copied data on the server. This correspondence is called mapping.
Click Autodetect. IntelliJ IDEA detects the user home folder settings on the FTP/SFTP server and sets up the root path according to them. The button is only enabled when you have specified your credentials.
Note, that this release introduces minor incompatibility of scp as mitigation of CVE-2019-6111. If your scripts depend on advanced bash expansions of the path during an scp download, you can use the -T switch to turn off these mitigations temporarily when connecting to trusted servers.
The libssh client and server now automatically load the /etc/libssh/libssh_client.config file and the /etc/libssh/libssh_server.config, respectively. This configuration file includes the options set by the system-wide crypto-policies component for the libssh back end and the options set in the /etc/ssh/ssh_config or /etc/ssh/sshd_config OpenSSH configuration file. With automatic loading of the configuration file, libssh now use the system-wide cryptographic settings set by crypto-policies. This change simplifies control over the set of used cryptographic algorithms by applications.
With the introduction of Red Hat Enterprise Linux 8.0, the IBM Virtual Network Interface Controller (vNIC) driver for IBM POWER architectures, ibmvnic, was available as a Technology Preview. vNIC is a PowerVM virtual networking technology that delivers enterprise capabilities and simplifies network management. It is a high-performance, efficient technology that when combined with SR-IOV NIC provides bandwidth control Quality of Service (QoS) capabilities at the virtual NIC level. vNIC significantly reduces virtualization overhead, resulting in lower latencies and fewer server resources, including CPU and memory, required for network virtualization.
This update introduces the ansible-freeipa package, which provides Ansible roles and modules for Identity Management (IdM) deployment and management. You can use Ansible roles to install and uninstall IdM servers, replicas, and clients. You can use Ansible modules to manage IdM groups, topology, and users. There are also example playbooks available.
This update introduces the ipa-crl-generation status/enable/disable commands. These commands, run by the root user, simplify work with the Certificate Revocation List (CRL) in IdM. Previously, moving the CRL generation master from one IdM CA server to another was a lengthy, manual and error-prone procedure.
The ipa-crl-generation status command checks if the current host is the CRL generation master. The ipa-crl-generation enable command makes the current host the CRL generation master in IdM if the current host is an IdM CA server. The ipa-crl-generation disable command stops CRL generation on the current host.
Additionally, the ipa-server-install --uninstall command now includes a safeguard checking whether the host is the CRL generation master. This way, IdM ensures that the system administrator does not remove the CRL generation master from the topology. 2ff7e9595c
