Hello, I have Fedora Core 3 linux and Samba 3.0.14a on a server that has 2 ethernet interfaces connected to the same LAN. The purpose to have such a server with 2 network cards is to serve 2 network shares with high traffic. I want the first share to be accessed trough the first network card (named drone.domain.com) and the second share trough the second card (named probe.domain.com). My DNS

I need to move a Samba 2.2.1 server form a Windows 2000 Domain network that is currently running in Mixed mode with a domain name if "ABC" to a pure Windows 2000 Active Directory network with a domain of "ABC.net". Do I need to do anything other than change the domain controller name listed in the password server property in the smb.conf? Thanks! Devin M. Rader, MCP

It's probably too late for you, but the best solution is to buy

Any recommendations on an economical layer 3 switch? Preferably something that you have hands on experience with connecting to IP phones with attached PCs? Specifically I need the ability to set the VLAN in the phone to tag voice packets and to set a native VLAN on a per port basis on the switch to put the untagged packets from the attached PC into a separate VLAN. POE is not a requirement

Hi all, sorry for the OT. Is IBM and Dell 42U rack compatible in dimension, rails, etc? Can we put IBM servers into Dell rack? Google says it depends. Much appreciated if you can share your experience. http://www.server-racks.com/why-all-racks-are-not-created-equal.html Thank you.

Yep, done that already, but it is not at all a good fit when the device is inside a drone flying around ;-) What we do have, is a fake file-system that keeps everything in memory, and after the profiling is completed we offload it for analysis. I guess I was hoping that there would be a more robust system agnostic implementation. Use of ‘mmap’ is similarly constraining. MartinO

Hi there, I'm currently trying to install a server with Centos 4.3 x86_64. I have issues installing drivers from a Driver disk, I got a driver(2810SA) from the Adaptec site, I started it up with "linux dd" It reads the disk fine .... I can see the aacraid module in the list but as soon as I choose it. Then I get a screen saying "Do you wish to load more Driver Disks?" I

Though quiet at the moment, my desktop sometimes sometimes makes a noise that I attribute to either a disk or a fan on its last legs. I'm looking for suggestions for distinguishing. For the disk, I expect I should use either hdparm of fsck. Even after reading the man page, I'm not sure how I would use hdparm. If I use fsck, what should I take as evidence of a bad drive? A good drive? Is

Ok... I asked a question a few months back about a 7960 that a user claims to be "shocking" her in her ear from time to time. A few others indicated they had similiar issues and alot of them seemed to stem from power over ethernet. Here's what we've done... We replaced the phone, ran two new cat5 cables to a different switch, put in a power brick and disabled power over

Hey folks, Does anyone know of a rack configurator that runs on CentOS? It does not have to even be very fancy - immediately I'm just looking for an easy way to keep track of what is in my racks, and being able to have a visual of it. Maybe juggle stuff around. Bonus if it does power calculations based on model numbers and so on - or data I punch in for each model. But really right

we have several servers on same rack and servers are all inside firewall. Centos version from 4.X to 5.X. sometime the connection are very slow (compare to servers on other racks also inside firewall). we discuss with network engineer he ask us use "ping" and traceroute" to check. Both tools response time are good but if we connect through application like Web browser, database,

Is there a list somewhere or a way to find the following: 1- All non US 48 area codes which can be dialed as 1+10 2- All strange area codes which are used for premium services such as 900-XXX-XXXX 3- Anything else that should be restricted if one was to restrict all calls to US 48 only I have found many list but it's tough looking at the entire list of area codes and pulling out each of them
