NetworkingLinuxFest 2008 Recap.Submitted by mhalligan on Sat, 2008-05-03 19:04.Mentoring | Networking
Last weekend we went to LinuxFest NorthWest 2008 in Bellingham, WA. It was a great time, we handed out a bunch of Tee-Shirts, met a lot of good people, and saw some interesting presentations. I even spoke with around half a dozen potential summer interns. mhalligan's blog | add new comment | 595 reads
tcpdropSubmitted by jm on Thu, 2007-07-05 15:14.Networking | Networking
A Tool to Drop TCP Sessions for the Solaris OS Stable There are occasions during an administrator's work when it is necessary to forcibly disconnect an established TCP session. However, no easy way exists for an administrator to drop an established TCP session without doing something heavy-handed, such as null routing all traffic from the client, adding an ipfilter rule (which, again, likely blocks more traffic than is strictly necessary), or taking the last resort of killing the associated server-side process. Ceri Davies ported tcpdrop from the BSD projects, which allows an administrator to easily drop any TCP connection without harmful effects elsewhere. add new comment | 714 reads
Asking for Comments: Samba Server Setup Experience Under Fedora Core 6Submitted by ant on Wed, 2007-05-23 12:43.Applications | Filesystems | Linux | Networking | Windows
Solved -- The box didn't retain my permissiable SELinux environment after a yum update. With a 'sudo setsebool -P samba_enable_home_dirs=1' there was a mighty noise and it started allowing public read-only access to the share. Someone liked my work (that they help me do) so well, that recently they requested I share the file with everyone on the LAN. I set out to create a publicly readable Samba share for the file. As a user, I issued a 'sudo yum install samba' and soon after started working on the default config file in /etc/samba/smb.conf. Here's the mix I came up with (which, keep in mind, doesn't work; I could use some help!) ant's blog | add new comment | 50644 reads

Enterprise class IP Address, DNS & DHCP management system. Stable The Carnegie Mellon NetReg package is a scalable and flexible Web-based system for managing networks. It consolidates information about DNS zones, subnets, machine registrations, and DHCP configuration, and provides tools for easy management. The system exports ISC BIND configuration and zones, and can update them via either static zone files or TSIG signed dynamic DNS updates. It also exports ISC DHCP configurations, and has a SOAP API for integration with other systems. add new comment | 1047 reads
Anthony Spina blogs on taggingSubmitted by doug on Fri, 2007-02-09 12:39.Naming | Networking
Anthony Spina writes an interesting article on the Splunk blog (here). Using network databases like this can make distributed operations much easier. How do you tag your machines? doug's blog | add new comment | 1078 reads

Fast enumeration of network services Active Nmap is a powerful tool for discovering hosts on a network and enumerating what service they are offering. This can be used to find vulnerable systems, to locate rogue services on your network or simply for a first step in troubleshooting. add new comment | 1461 reads
