For several days (at least 4) after using DHCP to switch the NetBIOS node type from h-node (8) to p-node (2) the systems have worked fine (the lease time is only three hours so everyone was affected reasonably early). This morning, however, the logon scripts would not run until I changed the node-type back to h-node. I have found some information regarding timing issues with VPN's but

Hi, I am running two hosts with xen-4.0.1 and dom0 kernel 2.6.32.41. The two hosts are connected to a Gigbit switch. Then I use iperf to measure the bandwidth and got the results of 200Mbit/second, which is only 1/5 of the available bandwidth. Then I boot these two hosts using a vanilla kernel of 2.6.32.34. The iperf reports 937Mbis/s, which is very close to the available link bandwidth. So why

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

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

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

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 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

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

Hi all, I have two prodction servers with FreeBSD 5.4 (all security patches are applied). They running some services like dns, ssh, http, ftp, etc. But I woukd like to encrypt some services for some hosts with ipsec when it is accessed. For example: - DNS resolution: not encrypted. - DNS replication master-slave: encrypted by ipsec. - Telnet: encrypted by ipsec for some hosts. Deny

I'm looking for an up-to-date howto on using Samba as an AD PDC. I've been using Samba since the days of yore, but have recently acquired the resources to take another stab at implementing an AD system using Samba. Perhaps it has escaped notice that the page with the link text "Official HOWTO" on samba.org points to https://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/

Hi all, i am trying to setup my first t1 in asterisk, i have been using asterisk for several years but ahve never needed a t1 line before. I have a sangoma card already in the server with 4fxo ports. Now i ordered two single port t1 line cards from sangoma for the two servers i am connecting with the point 2 point t1. I am currently at the location trying to set things up but have some

In the example I posted previous, there is an obvious gaping security hole, it would be trivial for someone to read the querystring and exploit it to make free phone calls, spoof caller ID (if you allow the CallerID to be set with a QueryString value), etc. You want to make damn sure that the URL is not publicly accessible or somehow obsfucate the querystring, or use POST. In my case, I

Hello List, I work for an IP communication provider in upstate NY as the engineer assisting our technical support team. We provide a number of different Telco systems to residential subscribers; and in an effort to more effectively trouble shoot termination problems I came up with the idea of creating a click to call system that will allow our agents to effortlessly place test calls.
