Hello, I'm an MD working in an eye clinic. I'm learning by myself to use R for use in my research works and for implementation in a software project. There are some authors who recomends the use of Cox regression as a substitute for Logistic regression (<a href="http://www.biomedcentral.com/1471-2288/3/21.pdf"> Barros AJD, Hirakata VN.

I''m trying to implement simple untagged vlans on our switch and have misconfigured something.. ISP gw is on the default vlan1 (untagged) Router eth1 is setup on the switch with default vlan1 and member of vlan4. eth0 is default vlan4 which connects to the clients that are all default members of vlan4 eth0 is x.x.x.86/28 This is what clients are connecting to as their gw.. (no

I?m looking to install a couple of SIP phones into a small/medium company. The easiest way would be to simply add the phones on the LAN network. But what would happened if someone make a huge file transfer: will it make trouble on the Sip connections ? I think so, that?s why I?m asking you if there is a good (better) way? Maybe connect SIP phones on a separate network and setup a linux box as

Is anyone aware of a package that can detect viri on the network & possibly alert when there are? Here is the scenario: Our network is utilized by guest users all the time, sometimes into the thousands. We see guests from all over with a variety of OSs & hardware, all of which, we have no control or say in that matter. I am looking for something that I can run in promiscuous mode and/or

My network uses reserved IPv4 addresses (192.168.2.0/24) behind a NAT firewall, but public IPv6 addresses behind a filtering firewall. My ISP (Comcast) assigns both IPv4 and IPv6 addresses dynamically. As a result, the IPv4 address of my internal Samba server is statically assigned, but its IPv6 address is dynamically assigned. The server has multiple IPv4 addresses assigned to it, all on

Hi all I have installed vyatta system, (vyatta-livecd-vc4-alpha2.iso ) on top of Centos5.

Hey gang, We have about 30 Cisco 79XX phones all running latest 7.5 SIP. We are also using all Cisco Switches and Routers. Everything works great except that when you reboot a phone it takes like 3-5 minutes for it to come up. The phones spend tons of time 'Configuring VLAN..' We don't run any VLANs. Is there some way to skip this? In the 'Network Settings' I have

Hey folks, I had some general questions and when reading through the list archives I came across an iSCSI discussion back in February where a couple of individuals were going back and forth about drafting up a "best practices" doc and putting it into a wiki. Did that ever happen? And if so, where is it? Now my questions : We are not using iSCIS yet at work but I see a few places

I am using 8021q vlans on my servers, and I cannot figure out how to make PXE/DHCP work. Has anyone figured out how to do this ?

Hello all, I'm looking to troubleshoot some echo issues and possibly "studdering" while using the speakerphone with the Intellitouch ITC3002. On the hardware end, i have a 2621 setup as the router with some policy maps for qos, and a 2900XL with cos priority set to 5. I have setup created 2 vlans currently (really small office), 1 for corp/data, and 2 voice vlan. Asterisk is on

I did a very quick search of the archive and couldn't find a readily available answer to this one: I'd like to convert, for example: c("a", "b", "a", "b") to c(1, -1, 1, -1) In the case of the first vector, it may be any length, but will always only have two unique values. It must always be replaced by corresponding values of 1 and -1. Any

I have recently upgraded my firmware from v6.3 to v7.4. Now when the phone is booted or rebooted, the initial screen "Initializing Vlan" takes forever to initialize before it initializes IP. Any ideas/Thoughts? (Trying not to Revert back to v6.3). -C -------------- next part -------------- An HTML attachment was scrubbed... URL:

Gordon, thanks! What sort of security implications did you have in mind? Just curious. Boris.

Hey, all. We're rolling out VoIP, and I'm wondering about PoE recommendations, as we're going to have to replace our current network equipment. My first inclination would be to just plunk down the cash and do a Cisco system, but I'm relatively certain that would get shot down by finance. Any recommendations for a couple-hundred-port solution with VLANs, PoE, and QoS? Don't

I'm working on some heatmaps, and the person I'm working with would prefer a red-black-green color palette (red denoting gene induction and green denoting gene repression). Does such a palette exist already? If not, is there an easy way to create one? Thanks, Jake

Just curious... Is there anyone out there who has given this outfit money and actually received any service from them?
