Hi, I am having some difficulties with matrix operations. It is a little hard to explain it so please bear with me. I have a very large data set, large enough that it needs to be split in parts in order to deal with. I can work things on these "parts" but the problem lies in adding together these parts for the final answer. So that been said, let's say that i split the data in 2

Hi, In populating our racks with several gigbit switches over the next few days, i'm wondering this: Is it over-engineering to seek out 550mhz rated cables over the typical Cat 6 250mhz rated cables? I've been advised (if you can a salesperson's words advice, heh.) that 250mhz is enough to handle traffic up to 10GB's. Should I just be happy with Cat6 for my GB switches or is

...ill having network problems b) if all of your dovecot tests is on one host ... disconnect it from the network and see if dovecot's auth finishes its tasks c) to clean up your network ... - use switches ... not hubs .... even inexpensive netgear switches is good enuff - use good 3-6' cat6e cables ... we'll assume the bldg's wiring is done to bldg specs - my guess, you're probably having cabling problems ) - separate slow devices from faster devices eg. separate printers onto its own network with a switch in between printers and everybody else - separate 10/100 de...

On my intranet, I sometimes transfer large files, about 4G, to an CentOS old box that I use for a web server. I transfer with ftp or sftp. Usually, before the file is complete, the transfer "stalls". At that point, ping from the destination box to the router fails. I then deactivate the net interface on the destination box and then activate it. Ping is then successful, and the

please can someone send to me his files like zaptel & zapta if he si using TE110P thank you

Hello, on an x64 ubuntu 15.10 desktop tinc 1.0.26 sometimes crashes on startup of the machine. eth0 (via good old cat6 cable, no wireless) is configured to use dhcp. The crash does not happen often, I have seen it in total maybe 2 or 3 times since installing 15.10 while it was still in alpha ( July 2015 ) until today. The desktop is not shut down very often, maybe once a week or every two weeks

I have to provision several dozen * users to a seperate building on our campus in the same subnet. Ordinarily, I'd just run a gigabit cat6 cable to another switch if it doesn't violate the 100 metre rule, but this building is several hundred metres away from my backbone. My only option for cabling to the remote building is copper. My plan is to provision them with a Linux bridge with 4

Thanks for your tip regarding the busy network. I am using a one year old Cisco Catalyst 2960S (WS-C2960S-48TD-L) with cat6e cables and my network should not be overloaded as far as I know. My mailbox and mail proxy servers are on two different virtual machines on two different servers. It could be possible that it is something with the virtualization but my other VMs do not have any connection time outs or anything. I w...

I've been tasked with fitting out an appartment building with a phone system. The entire appartment is getting broadband, with Cat6 Cables into each appartment and fibre down the trunk. I was hoping to have PSTN in the basement connecting to the IP system. Today I found out however that one of the services will be paid TV - and it will need a PSTN backchannel - ie a modem. The set top

Hi, I am trying to optimize my gigabit network. I have two Intel 1000 MT Gigabit Server Adapters, which support Jumbo Frames -- as well as a Switch that supports Jumbo Frames. However, I am observing some strange behavior in my file transfers from Windows XP to Linux and I am wondering if it has anything to do with the way the Samba variables are set on my Linux box? The "strange

I've got a Dell Precision Workstation 490 with 64-bit Centos 5, fully updated, with an on-board Broadcom 57xx gigabit Ethernet controller, updated BIOS, 1 GB switch, and /var/log/messages and dmesg both claim the link is 100 Mb, not 1 GB. I tried setting eth0 to mtu 9000 but got an error in going so. What do I need to do to have the card see 1 gb? Thanks. Scott

In the next few months I'll be moving and will have a room specifically for my office. As part of this move, I'll be putting in cat5e or cat6 throughout the new location and extra phone pairs. I'll want to replace my Talkworks/WinfaxPro based voicemail system with an Asterisk system, so what do I need to do cabling wise to make best use of Asterisk? I'll have at 2 phone

I'm having issues with echo. My setup is Polycom IP501 phones connected to an Adit 600 via T100P. 13 Lines going to the Adit. All echo so far is on the local side (Employees hears own voice, but only on some calls). Watching the channel with ztmonitor, I notice that TXGAIN is pegged out most of the time. RXGAIN is anywhere between 45 and 60%. Is it safe to assume that playing around
