8.10, vmware server 2.0, no vmnet0 [Archive] Sergio Ruocco January 14th, 2009, 05:21 PM Hi to all! I have EXACTLY the same problem. I am running Ubuntu 8.10 (with the latest updates & patches), VMware ServerVersion 2.0.0Build 122956, on a Mac Pro (server, not laptop) I installed a Ubuntu8.10 in a VM (a ready-made VM "appliance"), that works perfectly with NAT/hostonly interfaces. However, I am struggling to get it working with a BRIDGED interface to eth1, using a second public static address, so that the virtual Linux machine can be accessed from the outside.
According to a friend, who admnis tens of these things for his company, networking in the guest is configured correctly. The only problem I can see is that VMWare's vmnet0 does not show up if ifconfig: [sergio 17:05 ~]$ ifconfig (I removed the static public IP from eth0) I deleted the entire network configuration, and re-done as the standard (vmnet0 bridged to eth1, vmnet1 host only, vmnet8 NAT). .... values that you may need to migrate to your current datastores.xml.
Securing SSH On Ubuntu With WiKID Two-Factor Authentication. SSH offers a highly secure channel for remote administration of servers. However, if you face an audit for regulatory or business requirements, such as Visa/Mastercard PCI, you need to be aware of some potential authentication related short-comings that may cause headaches in an audit. For example: There is no way to control which users have public key authorization There is no way to enforce passphrase complexity (or even be sure that one is being used) There is no way to expire a public key In this document we are going to demonstrate how to combine two-factor authentication from WiKID on Ubuntu. The WiKID Strong Authentication System is a commercial/open source two-factor authentication solution. First, we will configure a domain on the WiKID server, then add the targeted server as network clients to the WiKID server, and finally configure the Ubuntu box via pam-radius. The WiKID Strong Authentication server is now available for Ubuntu.
Adding A Domain To The WiKID Server Just above: PBX in a Flash. Appliance Details Introduction PBX in a Flash is an aggregation of open source tools used to build a flexible, extensible VoIP telephony PBX. The open source tools include the CentOS 5.5 operating system, Apache web server, MySQL database management system, PHP, and a choice of Asterisk 1.4, 1.6.2, or 1.8 plus FreePBX 2.6 or 2.8 GUI. Check out this Nerd Vittles Article for the latest OpenVZ template and step-by-step VM installation instructions.
Both Proxmox Network Types are supported, and both are covered in this Nerd Vittles Article. Check out the PBX in a Flash forum link for support. Download latest PIAF OpenVZ template. To transform the PBX in a Flash VM into a turnkey system, run the Incredible PBX Installer script. NOTE: A new 64-bit PBX in a Flash OpenVZ template has just been released. Securing Your System Security Matters especially with a VoIP telephony system. To activate the IPtables firewall, shut down all running VMs. Using PBX in a Flash with Proxmox cd /root . How to securely control another Mac over the internet - Mac OS X.
I decided to put together his how-to after setting this up for my dad, and figuring there are probably a number of others out there who serve as the de facto tech support person for friends and family in remote locations. The idea is to be able to remotely view and, if needed, control another Mac to help teach a new Mac user how to do something or fix their problem. This isn't the fastest thing in the world mind you -- anything they do with much in the way of graphics, like iPhoto, takes a long time to paint on my end -- but it definitely works well enough for what I need. My method certainly isn't the only way of doing it, but it meets my criteria, which are: So, the first thing I did was upgrade his Mac to the latest ARD client software.
Once that was installed I went into the Sharing prefrences pane on the Mini and started the ARD service. Next I enabled Remote Login (i.e. ssh server) on my PowerBook. Next I installed Chicken of the VNC on my Powerbook. Almost there! That's about it. Secure your SSH server with Public/Private key authentification. Open SSH is the most widely used SSH server on Linux. Using SSH, one can connect to a remote host and gain a shell access on it in a secure manner as all traffic is encrypted. A neat feature of open SSH is to authenticate a user using a public/private key pair to log into the remote host.
By doing so, you won't be prompted for the remote user's password. This tutorial will describe how to create a SSH public/private key pair, how to enable key based authentication and finally how to disable password authentication. Even though SSH is secured, there is tons of brute force attacks against SSH server which will attempt to gain access to your machine. By using key based authentication and by disabling the standard user/password authentication, you will reduce the risk of having someone gaining access to your machine. This tutorial suppose that you already have your remote machine running a SSH server. On Debian Stable, you need to install: #apt-get install ssh On the server and:
BigAdmin Feature Article: Secure Shell: Part 2. Oracle acquired Sun Microsystems in 2010, and since that time Oracle's hardware and software engineers have worked side-by-side to build fully integrated systems and optimized solutions designed to achieve performance levels that are unmatched in the industry. Early examples include the Oracle Exadata Database Machine X2-8, and the first Oracle Exalogic Elastic Cloud, both introduced in late 2010. During 2011, Oracle introduced the SPARC SuperCluster T4-4, a general-purpose, engineered system with Oracle Solaris that delivered record-breaking performance on a series of enterprise benchmarks. Oracle's SPARC-based systems are some of the most scalable, reliable, and secure products available today.
Sun's prized software portfolio has continued to develop as well, with new releases of Oracle Solaris, MySQL, and the recent introduction of Java 7. Oracle invests in innovation by designing hardware and software systems that are engineered to work together.
