  • Alternative Methods of Sharing Folders in Windows?

    - by Blaenk
    Hey guys. I'm running Windows 7 and as of now I simply share folders as one usually does in Windows. I then have a MacBook with Leopard (Now Snow Leopard) which I use to connect to my computer to mount the shares by going to Finder, then CMD + K and typing smb://BlaenkPC (The name of my PC) into the address box. This consequently connects to my computer and mounts all of the shares. The problem is that sometimes, if for example I close my MacBook (Which makes it go to sleep) or sometimes even without doing that, the connection somehow drops. Sometimes I close the MacBook and upon re-opening it, everything still works; it's random. It still shows the computer as being connected, but it just shows 'loading' indefinitely. If I hit 'eject' with the intention of re-connecting to the computer, it disappears from the sidebar (The Computer Icon) in Finder, but I cannot re-connect. Activity Monitor (or ps aux, whichever) both show hung instances of umount; one for each share that was mounted. I cannot kill these processes with kill or killall (Yes, even with sudo, and sending signal -9). This has happened to me before, and here is another person who has experienced this. My question boils down to this: Is there an alternative method of sharing folders in Windows, that my Mac can read/understand, that is possibly more reliable and preferably just as fast? I usually use the mounted shares to watch television episodes off my computer, or movies, etc. (In other words, I open them in VLC and they automatically stream from my computer). As far as I can tell, this is a problem with the Samba protocol. I have heard of NFS, but I am not sure if I would have to re-format my drives, or what. I don't mind running a service or daemon to allow the sharing of the folders, I just want it to be done and hopefully in a better way than typical Windows shares through Samba. Usually when I encounter this problem, which is often (read: every day), I have no other option but to restart the MacBook. As I stated in the first question I linked to, shutting down and restarting don't work; I have to manually force the shutdown by holding the power button. I have not modified my installation of Mac OS X in any hackish way, so I doubt it's something with the Operating System, but worst come to worst, I might end up reformatting and doing a clean install to see if that fixes anything, as I am at a complete loss as to what may be causing the problem, and no one else seems to have any idea or care, despite there being quite a few people suffering from this problem, as my research has shown. Any pieces of information that can help are extremely appreciated. You don't have to answer every question on here, but maybe even some insight as to why it might not be possible to kill those hung umount instances for example, or why I may not be able to reconnect using samba (Is it something regarding the way the protocol works?). One thing to note is that I have another computer in the home network that doesn't seem to have this problem. However, it is also running Windows 7 (Note though that I am not using the homegroup feature, but the typical windows sharing feature). My only deduction is that the problem is being caused by the way the Mac (Or Samba implementation, whichever) is handling things. Perhaps it is a limitation.

  • Gigabit capacity

    - by abronte
    Do gigabit ports have a total throughput of 1 gigabit so that you could be sending 800 mbit and receiving 200 mbit at the same time. Or is it 1000 in and 1000 out?

  • Wireless to Wireless Transfer Slow on a Linksys WRT54GL

    - by Kyle Brandt
    The Situation: When I try to transfer a file from one computer to another that are both connected via wireless on a WRT54GL (in a office) with dd-wrt firmware I often get bad speeds. In generally they average around 100 kilobytes a second. Either computer can download via wireless from the Internet at at about 2 megabytes a second. The speed is slow with the transfer of one large file. There are about 20 other wireless networks that the computers can see, so there is a lot of noise, but I don't have the equipment to really monitor the frequencies well. But that still seems pretty slow. I thought maybe it was the transmit on each card, but even when they are 5 feet away with a line of sight I still get these speeds. According to Linux both cards are operating at 54g. My Questions: Is this normal for this sort of consumer level wireless equipment? Anything I can do to improve it? why is wireless to wireless transfer slow when everything else isn't? Whats steps might I take to figure out what is happening? For example, are lots of packets not making to the access point requiring retransmissions? Above all, I want to find out what the problem actually is. This may seem odd, but at this point I am more interested in understanding what the problem is than fixing it. What I have tried: I have tried messing with lots of settings. Different channels, xmit power, G-Only, none of which has made anything any better. I've also tried upgrading to newer dd-wrt firmware version and doing a reset to wipe out the settings.

  • Vlan and Switch setting - dummy

    - by Andras Sebestyen
    I need to speak tomorrow the network engineer and I would like to understand his so apologise for the Dummy question: In the school we have a cab with a 24 port Netgear manageable switch with an admin and curriculum VLAN settings. Usually, as I over heard, in the morning and around 4.30pm there are a slowdown period on the computers which connect to this switch. No one could track this back yet. Questions: What is the best way to track back this slowdown Would it be a temporary solution to physical separate the two network with 2 switches If that would work how can I link them together to be able to see the curriculum from the admin side. Do I need an extra router then? Too many questions but I have no clue where to start and the gentleman will be paid by hours... can you see where I am coming from?:) Could you guide me in the right direction please? Any comment would be appreciated and please send links if you down vote the question:)

  • Why is my eth0 getting a dynamic ip when it is configured to be static?

    - by sdek
    For some reason our office linux box is being assigned an ip address via dhcp and I don't know why. What is confusing to me is that when I check system-config-network it shows that my eth0 is setup to be a static ip address. And /etc/sysconfig/network-scripts/ifcfg-eth0 also shows it is setup to be a static ip, yet it is getting a different ip address than the one specified in the ifcfg-eth0. Let me know if you have any suggestions on or ideas on where I can look next. Here are a few details that might help you figure out what an idiot I am :) Fedora 11 Router in front of this box is running dhcp, starting at 10.42.1.100 This box is configured to be 10.42.1.50 (at least I think it is!), subnet 255.255.255.0 (which is same as the router's lan subnet) Instead of having the static IP, this box is getting assigned 10.42.1.100. Here are the ifcfg-eth0 details DEVICE=eth0 BOOTPROTO=none ONBOOT=yes TYPE=Ethernet USERCTL=no NM_CONTROLLED=no NETMASK=255.255.255.0 IPADDR=10.42.1.50 GATEWAY=10.42.1.1

  • Cannot browse remote networks even with WINS configured

    - by paradroid
    As the NetBIOS protocol acts on Layer 2 and so is not routable, In order to enable network browsing of remote networks, WINS has been installed and configured on two domain controllers, both of which are on different networks. The WINS servers seem to be replicating with eachother, and each has 127.0.0.1 set as the Primary WINS Server in each of their LAN interface properties, with nothing entered for Secondary WINS Server. The DC which holds the PDC Emulator FSMO role has the Computer Browser service running and set to Auto start, and it has the WINS/NBT node type network setting at 0x8 (H-node - Hybrid node). Remote network browsing does not work. Is the WINS/NBT node type correct for this scenario? The reason why I think it may not be the right one is because I set the DHCP Server's 046 WINS/NBT node type option to 0x8 as well, after which the DHCP clients started to disappear from the Network folders. When that option is not set, does it default to B-node (Broadcast node)? Or could it be a problem with the WINS servers setup?

  • Managing an application across multiple servers, or PXE vs cfEngine/Chef/Puppet

    - by matt
    We have an application that is running on a few (5 or so and will grow) boxes. The hardware is identical in all the machines, and ideally the software would be as well. I have been managing them by hand up until now, and don't want to anymore (static ip addresses, disabling all necessary services, installing required packages...) . Can anyone balance the pros and cons of the following options, or suggest something more intelligent? 1: Individually install centos on all the boxes and manage the configs with chef/cfengine/puppet. This would be good, as I have wanted an excuse to learn to use one of applications, but I don't know if this is actually the best solution. 2: Make one box perfect and image it. Serve the image over PXE and whenever I want to make modifications, I can just reboot the boxes from a new image. How do cluster guys normally handle things like having mac addresses in the /etc/sysconfig/network-scripts/ifcfg* files? We use infiniband as well, and it also refuses to start if the hwaddr is wrong. Can these be correctly generated at boot? I'm leaning towards the PXE solution, but I think monitoring with munin or nagios will be a little more complicated with this. Anyone have experience with this type of problem? All the servers have SSDs in them and are fast and powerful. Thanks, matt.

  • Accessing local resources over wifi with a BES-connected Blackberry

    - by bshacklett
    I'm trying to get to a local web site on my LAN at 192.168.1.10 with my Blackberry, but I'm getting a message saying the server did not respond. I know that some, if not all, internet traffic on a BES-connected blackberry goes through the BES. This is clear because I can access internal resources on my employers network via the mobile network. Is there any way for me to specify that the device should attempt to route directly over wifi before it tries to connect via the BES server at work?

  • network topology including many services

    - by mete
    I know this is yet another question on how to setup network but I hope you are not bored of such questions yet. The site is also an office, so it includes windows dc, windows ad, exchange, sql, file sharing, development app servers and other pcs. In addition to office (internal) things, there are both test and prod environments consisting of a web server-app server-sql stack. There is also ftp service open to public. I consider: dmz1 - web server - exchange edge - ftp dmz2 - app server - sql for app server internal - dc and ad - exchange hub and transport - internal file sharing - sql for internal use - app servers for internal use - pcs public - dmz1, only web, ftp and smtp public - dmz2 not possible public - internal not possible dmz1 - dmz2 is possible from web servers to app servers by using http or ajp dmz1 - internal is only possible for exchange, otherwise not possible dmz2 - internal not possible Does this sound ok ? Any other recommendations ? It will be configured using either MS ISA or Jupiter SSG. Thank you.

  • How to pipe internet radio into a tuner?

    - by JW
    UPDATE: Thanks everyone for the ideas! This was an area I knew very little about but now I can talk with a little more expertise about it. Much appreciated! Visited my dad this weekend and he wants to pipe some internet radio he's found down to a tuner on quite a distance away in the house. He uses computers for only very basic things: e-mail, getting the Post crossword, checking Yahoo!, checking recipes, etc. There's currently one computer in the house (no router). My initial suggestion (without any research whatsoever) was to get a wireless router and a netbook for downstairs near the tuner, but he initially wasn't too keen about having another computer down there. Anyway, is there any computer hardware that could magically pipe the audio output from the computer down to one set of (RCA) audio inputs on the tuner? Wireless isn't necessary but it probably would be easier. Anyway, thanks for your suggestions! UPDATE Thanks everyone! Voted up all of your suggestions now that I have 15 rep. Much appreciated.

  • AuthInfoRequired cups overwrites

    - by mooscape
    My problem is basically identical to the following: http://bbs.archlinux.org/viewtopic.php?id=61826 Put simply, I have a machine in ubuntu trying to connect to another ubuntu machine via a network in order to use the printer attached. There is no problem printing until I restart the guest machine. Immediately it overwrites the printers.conf file (under /etc/cups/printers.conf). It always adds the same line: AuthInfoRequired username,password I stop cups and change it to *#*AuthInfoRequired username,password to comment out the command. Start cups. Works great 'til the next shutdown. Then it gets overwritten again. Googling indicates it may be GTK problem and not CUPS, but I have found no permanent solution to date. Any suggestions appreciated ....

  • Vista laptop 1 connects to network but Vista laptop 2 doesn't

    - by Jaips
    (Sorry if this is a dulipcate. I did a hunt but couldn't find matching question) We recently got a new router for our network (thomson TG585v8). It was already pre-configured by the ISP and was easy to setup. Both Vista laptops in this home network connected without trouble as well a iPod touch, all via wifi. In the last two days one of the laptops has been unable to connect cleanly to the network (connects as unidentified network). The other laptop, and iPod have not had any issues. I can't think of anything that has changed to make this happen now. I have rebooted the laptop and the router. I have updated the laptop wireless driver I have checked the laptop is set to automatically get IP I have logged into the router which correctly identifies all three wireless devices. The problem laptop connects via LAN without issue. Some things that may or may not matter: The problem laptop also sometimes uses a 3G dongle Both laptops use Windows Live Mesh to sync folders Laptop is usually set to go to sleep NB: it seems this is an intermittent issue, after an hour (since i noticed it) it seems to have fixed itself. Would love ideas though to solve this problem for good.

  • Teamed network cards on a Proliant Server

    - by Matt
    We have 4 network cards in a Proliant server with Server 2008R2 running Exchange 2010, with 1 card set to a static IP address and the other 3 set to DHCP. I just need some clarification as I have not teamed network cards. Do all the network cards need to have a static IP when I set as a team. The connection that has the static IP is the IP that I need to use for the Server. Is it possible to set the teamed cards to the same static IP or do I have to change the static IP to another IP then use it for the teamed IP? I will be using HP Network Configuration Utility to set this up.

  • Private staff network within public network

    - by pianohacker
    I'm the sysadmin at a small public library. Since I got here a few years ago, I've been trying to set up the network in a secure and simple way. Security is a little tricky; the staff and patron networks need to be separated, for security reasons. Even if I further isolated the public wireless, I'd still rather not trust the security of our public computers. However, the two networks also need to communicate; even if I set up enough VMs so they didn't share any servers, they need to use the same two printers at the very least. Currently, I'm solving this with some jerry-rigged commodity equipment. The patron network, linked together by switches, has a Windows server connected to it for DNS and DHCP and a DSL modem for a gateway. Also on the patron network is the WAN side of a Linksys router. This router is the "top" of the staff network, and has the same Windows server connected on a different port, providing DNS and DHCP, and another, faster DSL modem (separate connections are very useful, especially as we heavily depend on some cloud-hosted software). tl;dr: We have a public network, and a NATed staff network within it. My question is; is this really the best way to do this? The right equipment would likely make my job easier, but anything with more than four ports and even rudimentary management quickly becomes a heavy hit on our budget. (My original question was about an ungodly frustrating DHCP routing issue, but I thought I'd ask whether my network was broken rather than asking about the DHCP problem and being told my network was broken.)

  • Creating an office network and monitoring all activity without a proxy

    - by Robert
    We are setting up our office network and would like to track all the websites visited by our employees. However, we would not like to use any proxy based solutions. Our work is highly dependent on applications in which you cannot configure a proxy. Hence, the approach we would like to follow is setting up a router inside a computer (something like this : http://www.techrepublic.com/article/configure-windows-server-2003-to-act-as-a-router/5844624) This will also allow us to attach multiple ethernet cards and have redundancy in internet connectivity with complete abstraction from the user about which connection is being used. But most importantly, since all the traffic will be going through the computer (configured as a router) I assume there will be a way to run packet analysis on all the request / responses being made. For example, list all the FTP servers connected to (port 21), give a graph of all the URLs visited per day by frequency. Is there already a software which does this ? Or is it possible to build something like this ?

  • Connecting both WAN and LAN ports to the same hub

    - by C. Lee
    For some reason I wish to connect the WAN port and the LAN port on a router to the same hub and make the hub is connected to both networks, the Internet and a private network. Below is a diagram of the network configuration I'd like to build. I tried this and it didn't work as expected. PC 1 has no problem, but PC 2 cannot connect to the Internet. When I ping 192.168.0.1 from PC 2, all packets are lost. It works well when PC 2 is connected directly to the router. What's the problem with the network configuration above?

  • How to block/avoid a particular IP when connecting to websites?

    - by Mark
    I'm having trouble connecting to a particular website. I can view it through a proxy, but not from home. So I ran a traceroute: Tracing route to fvringette.com [76.74.225.90] over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms <snip> 2 * * * Request timed out. 3 9 ms 7 ms 27 ms rd2bb-ge2-0-0-22.vc.shawcable.net [64.59.146.226] 4 8 ms 7 ms 7 ms rc2bb-tge0-9-2-0.vc.shawcable.net [66.163.69.41] 5 10 ms 9 ms 9 ms rc2wh-tge0-0-1-0.vc.shawcable.net [66.163.69.65] 6 27 ms 23 ms 22 ms ge-gi0-2.pix.van.peer1.net [206.223.127.1] 7 18 ms 18 ms 20 ms 10ge.xe-0-2-0.van-spenc-dis-1.peer1.net [216.187.89.206] 8 9 ms 11 ms 10 ms 64.69.91.245 9 * * * Request timed out. 10 * * * Request timed out. ...

  • Is browser based wireless authentication secure?

    - by johnnyb10
    Our wireless network previously used a preshared WPA/WPA2 key for guest access, which allows them access to the Internet. (Our employee access uses 802.1x authentication). We just had a wireless consultant come in to fix various wireless issues we had; one of the things he wound up doing was changing our guest access to HTML-based instead of the preshared key. So now that guest SSID is open (instead of using WPA) and users are presented with a browser-based login screen before they can get on the Internet. My question is: Is this an acceptable method from a security standpoint? I would assume that having an open network is necessarily a bad idea, but the consultant said that the traffic is still using PEAP, so it's secure. I didn't get a chance to question him further on this because we ran late and a bunch of other things came up. Please let me know what you think about the advantages/disadvantages of using HTML-based wireless authentication as opposed to using a preshared WPA key. Thanks...

    Looking for a stepped-up ALIX or Soekris embedded network appliance to load pfSense and/or handle other FOSS-based network roles. Main criteria is a GbE NICs (will be used for core routing/firewalling with managed GbE switches), DDR3 RAM capable, and multi-core/Intel Atom processor, in a 1U rack-mountable case or smaller. Axiomtek has the ideal product but I don't think they have retail channels.

  • Cannot Resolve Host Or Access Website Through Router

    - by Boris_yo
    This is weird. I am on Windows XP with Edimax BR 6204Wg. I have 3 devices - 2 laptops and 1 smartphone. 1st laptop and smartphone are connected through WiFi to router and 2nd laptop is connected through LAN to router. Before firmware upgrade i did not try to access website but after firmware upgrade to latest version: http://www.edimax.eu/en/support_detail.php?pd_id=11&pl1_id=3#02 i had problems resolving host, pinging, tracerting and accessing website. Sometimes ping and tracert work but i cannot access website and sometimes i can access website but ping and tracert do not work. Weird? I downgraded to previous version and no changes. If i can no longer access that website through Internet Explorer, i can access it in Firefox. I tried deleting cookies, clearing cache and that seem not make difference. Switching LAN port did not make difference. When i disconnect router and connect laptop through LAN to internet modem, everything is normal. I tried resetting router, resetting to factory default settings and all did not help. At the moment i can access website on laptop connected through LAN from Firefox and Internet Explorer, but on my smartphone i can access website only with Opera but not with built-in browser and Skyfire. UPDATE: I just could only access with Internet Explorer but not with other browsers on my PC. Minutes later i could access with all browsers. But on smartphone i could only access with Opera and not with other browsers. I am confused. I also determined that sometimes i can access and sometimes can't. What is also weird is that when ping and tracert cannot resolve host, i still am able to access website.

  • how to broadcast a PXE server like Trinity Rescue Kit

    - by Larry G. Wapnitsky
    I would like to set up a portable PXE server for diagnostic purposes. The issue is that I won't always have access to the DHCP server, or the router itself (sometimes a home router) doesn't have an easily accessible place to set the servername/file for broadcast. I know that Trinity Rescue Kit is able to broadcast its PXE server without its own DHCP server. Can anyone point me in the direction to set this up on my own (without Trinity)? Thanks.
