After trying the kioslaves in the desktop of my choice (KDE) and the FUSE programs Fusesmb and SmbNetFs, I was not really satisfied. There had to be a way to let my computer discover all the workgroups/domains, the hosts and the shares, and mount a share on a hosts on demand. falko Wed, 29 Aug 2007 09:56:28 GMT http://www.howtoforge.com/automatic-file-replication-mirror-across-two-storage-servers-with-glusterfs-3.2.x-on-ubuntu-12.10 This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 12.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 12.10 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA. falko Tue, 22 Jan 2013 12:26:48 GMT http://www.howtoforge.com/boot-linux-over-http-with-netboot.me This tutorial shows how you can boot Linux over HTTP with netboot.me. All that users need is Internet connectivity and a small program (gpxe) to boot the machine. This gpxe program provides network booting facility. netboot.me allows you to boot into the following distributions: Debian, Fedora, OpenSUSE, and Ubuntu. netboot.me provides gpxe images for USB sticks, CDs, and also for floppies, i.e., you can boot from a USB sticks, a CD, or a floppy. falko Thu, 01 Oct 2009 12:41:50 GMT http://www.howtoforge.com/how-to-enable-networking-in-xen-guests-on-hetzners-new-eq-servers-debian-lenny This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests. falko Tue, 27 Oct 2009 23:58:22 GMT http://www.howtoforge.com/zabbix_network_monitoring_debian_etch Zabbix is a solution for monitoring applications, networks, and servers. With Zabbix, you can monitor multiple servers at a time, using a Zabbix server that comes with a web interface (that is used to configure Zabbix and holds the graphs of your systems) and Zabbix agents that are installed on the systems to be monitored. The Zabbix agents deliver the desired data to the Zabbix server. This tutorial shows how you can install the Zabbix server and agent on a Debian Etch system. falko Fri, 13 Jul 2007 10:10:25 GMT http://www.howtoforge.com/lintrack_lan_gateway_openvpn_bridge This tutorial will guide you through installation and configuration of Lintrack, a GNU/Linux distribution specialized in networking tasks. We will give two LANs access to the internet along with DHCP and DNS cache servers, and then we will connect our networks using OpenVPN in bridging mode. You should be running all these in well under an hour, thanks to the unified configuration interface of Lintrack. falko Wed, 09 May 2007 17:16:02 GMT http://www.howtoforge.com/monitoring_network_latency_smokeping_debian_etch This guide shows how to install and configure Smokeping on Debian Etch to monitor network latency. From the Smokeping web site: "SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm data-store and to draw pretty graphs, giving up to the minute information on the state of each network connection." falko Sun, 16 Sep 2007 11:03:07 GMT http://www.howtoforge.com/monitoring-network-latency-with-smokeping-ubuntu-9.04 This guide shows how to install and configure Smokeping on Ubuntu 9.04 to monitor network latency. SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm data-store and to draw pretty graphs, giving up to the minute information on the state of each network connection. falko Thu, 16 Jul 2009 11:29:43 GMT http://www.howtoforge.com/mounting-remote-directories-with-sshfs-on-ubuntu-11.10 This tutorial explains how you can mount a directory from a remote server on the local server securely using SSHFS. SSHFS (Secure SHell FileSystem) is a filesystem that serves files/directories securely over SSH, and local users can use them just as if the were local files/directories. On the local computer, the remote share is mounted via FUSE (Filesystem in Userspace). I will use Ubuntu 11.10 for both the local and the remote server. falko Tue, 06 Dec 2011 10:36:53 GMT http://www.howtoforge.com/network-analysis-with-wireshark-on-ubuntu-9.10 Wireshark is a network protocol analyzer (or "packet sniffer") that can be used for network analysis, troubleshooting, software development, education, etc. This guide shows how to install and use it on an Ubuntu 9.10 desktop to analyze the traffic on the local network card. falko Sun, 21 Feb 2010 15:40:11 GMT
