• How can I run a speed test for Netflix and Hulu?

  - by Brennan Stehling

  Since the FCC rules were struck down I have noticed that Netflix and Hulu often stall on my Time Warner home connection. I've heard others are experiencing the same delays. I use Speedtest.net regularly from my computer and phone to check my connection and typically at home I get 10 to 15Mbps and occasionally higher. Currently it is around 10Mbps yet Hulu is stalling. Is there a way to specifically test my speeds for streaming Netflix and Hulu?

• TCP/IP Ilustrated 1 second edition [on hold]

  - by user196821

  Well, I want to read and learn about how tcpip works in detail, so I got a copy of the well known book of Richard Stevens. But after a little, I discovered there is a second edition of the book, so I checked it out. But surprisingly, the second edition does not cover some subjects that the first actually does (like telnet, ftp, smtp etc...), so I thought "well I just have to read the misshing chapters on the first edition", but if they removed them in the second, it is for a reason. Is there really a good reason for that?

• Where should executables be run from? Network share or client?

  - by user74150

  We have an executable that is used by 50+ client machines on a network and upgraded regularly. Is it acceptable to put the executable on a network share and have the client machines run it from there via a shortcut on their desktop? That way when we upgrade the .exe we can simply replace the one file with a new one and all clients will be accessing the new one. How will a slow or unstable network handle this? If this is not acceptable, what would be the best way to keep all clients updated with the latest .exe?

• How do I make dnsmasq serve IP addresses via IPoIB?

  - by Matt

  I have a cluster farm that I'm setting up. The nodes (computers in the farm) are connected via ethernet & IP over Infiniband. I'm needing to netboot the nodes and thought dnsmasq would fit well as it provides all the features including support for DHCP over IB and it works great for our ethernet setup. However, I can't seem to get it to provide IP addresses to the infiniband adaptors on the nodes. Each node is running an Ubuntu desktop 12.04 LTS. The dnsmasq server is running on ubuntu server 12.04LTS and has the following test config: dhcp-authoritative domain-needed bogus-priv expand-hosts no-hosts domain=local dhcp-range=eth0,10.0.0.10,10.0.0.255,12h dhcp-option=eth0,3,10.0.0.1 dhcp-range=ib0,10.1.1.10,10.1.1.255,12h dhcp-option=ib0,3,10.1.1.1 log-queries log-dhcp IPoIB works between nodes when configured statically but not with dhcp. On the nodes the file /etc/network/interfaces contains auto lo iface lo inet loopback auto ib0 iface ib0 inet dhcp #iface ib0 inet static #address 10.1.1.5 #netmask 255.0.0.0 up echo connected >`find /sys -name mode | grep ib0` Is there something I need to do on the client or server end to make this work?

• Subdomains for different applications on Windows Server 2008 R2 with Apache and IIS 7 installed

  - by Yusuf

  I have a home server, on which I have installed Apache, and several other applications that have a Web GUI (JDownloader, Free Download Manager). In order to access each of these apps (whether be it from the local network or the Internet), I have to enter a different port, e.g., http://server:8085 or http://xxxx.dyndns.org:8085 for Apache http://server:90 or http://xxxx.dyndns.org:90 for FDM http://server:8081 or http://xxxx.dyndns.org:8081 for JDownloader I would like to be able to access them using sub-domains, e.g, http://apache.server or http://apache.xxxx.dyndns.org for Apache, http://fdm.server or http://fdm.xxxx.dyndns.org for FDM, http://jdownloader.server or http://jdownloader.xxxx.dyndns.org for JDownloader First of all, would it be possible like I want it, i.e., both from LAN and Internet, and if yes, how? Even if it's possible only for Internet, I would like to know how to do it, if there's a way.

• CentOS Failover Cluster - SIOCADDRT: No such process (when adding a loopback)

  - by Steve Rolfe

  I'm trying to configure two web servers for a load balancing server. The load balancing aspect works fine (it sees both server, kills 'em if it needs to, and seems to direct traffic fine). The only issue is with the servers looping: /etc/sysconfig/network-scripts/ifcfg-lo:0 DEVICE=lo:0 IPADDR=<Virtual IP> NETMASK=255.255.255.255 ONBOOT=yes NAME=loopback Everytime I try a "service network restart" I get a SIOCADDRT: No such process when loading the loopback interface. Anyone have an idea what's causing this?

• Linux clients and Windows Servers can connect but not windows clients

  - by Mustafa Ismail Mustafa

  This is driving me insane because I can't make head or tails of it. We have two DCs (W2K3 SP1) and I'v tried this once on each machine as a sanity check. DHCP is being served by either one of the machines and all machines get an address no problem. The servers can connect/ping/browse to the www and so can all our linux clients. But NONE of our windows clients (all windows 7). I can do anything within the network, I can even ping the firewall/router but nothing from the windows clients is leaving the confines of our subnet. I don't get it. The linux and windows clients are both served from the same DHCP server, the gateway is the same, everything is the same. Anyone care to take a shot at how to resolve this? I tried adding explicit routes at the clients, but still no go. TIA SMIM

• I can't externally access my home server's wordpress website

  - by piratepartypumpkin

  Basically, I can access everything just fine using 127.0.0.1, but if I use my external IP (123.123.123.123), I get page not found. My router is port forwarding HTTP port 80 to port 8080 on my servers internal IP address. In other words: (Application: HTTP | Start: 80 | End: 8080 | Protocol: Both | IP Address 192.168.0.101 | Enable [YES]) I know it's forwarding properly, because when I stop port forwarding, I can access my router page by using my external IP. My virtual hosts file is: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /opt/lampstack-5.3.16-0/apps/wordpress ServerName example.com ServerAlias www.example.com </VirtualHost> and my httpd.conf file is: Listen 80 Servername localhost:80 DocumentRoot "/opt/lampstack-5.3.16-0/apache2/htdocs <Directory /> Options FollowSymLinks AllowOverride None Order deny, allow deny from all </Directory> <Directory "/opt/lampstack-5.3.16-0/apache2/htdocs"> Options FollowSymLinks AllowOverride None Order allow, deny allow from all </Directory>

• Can I use a wireless-N laptop as an NAS for seamless and fast data transfer and access?

  - by techaddict

  I have a nice spare laptop (Dell 15R, one year old) that I was wondering if I could use as an NAS. The laptop has an E-Sata port, and I was wondering if I could set it up and plug in a few hard drives permanently (meaning I won't be unplugging it) to the eSata port and use the laptop as a wireless NAS to seamlessly and wirelessly store and access my files. To see more about what I'm looking for in the NAS to see if it's possible to use my other laptop for this purpose, see my other question: Is it possible to have a wireless in-house NAS with wireless data transfer rates of equivalent to SATA speeds? Alternatively, would it be better to sell the laptop and buy a dedicated NAS?

• Failed to mount to nfs server with "Program not Registered"

  - by Farrel

  I'm trying to setup nfs server on Fedora 17 and I'm getting "Program not Registered" error when I'm trying to mount. I guess the main reason for this is rpcbind. I'm a newbie in linux, so I don't know what info should I provide you with. Here is some info that might be useful. rpcinfo -p program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100005 1 udp 20048 mountd 100005 1 tcp 20048 mountd 100005 2 udp 20048 mountd 100005 2 tcp 20048 mountd 100005 3 udp 20048 mountd 100005 3 tcp 20048 mountd 100024 1 udp 42223 status 100024 1 tcp 50054 status cat /etc/exports /home/Farrel/prog 192.168.xxx.xxx (ro,sync) service nfs status Redirecting to /bin/systemctl status nfs.service nfs-server.service - NFS Server Loaded: loaded (/usr/lib/systemd/system/nfs-server.service; enabled) Active: active (exited) since Fri, 02 Nov 2012 09:29:04 +0300; 5min ago Process: 924 ExecStartPost=/usr/lib/nfs-utils/scripts/nfs-server.postconfig (code=exited, status=0/SUCCESS) Process: 909 ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS ${RPCNFSDCOUNT} (code=exited, status=0/SUCCESS) Process: 885 ExecStartPre=/usr/sbin/exportfs -r (code=exited, status=0/SUCCESS) Process: 864 ExecStartPre=/usr/lib/nfs-utils/scripts/nfs-server.preconfig (code=exited, status=0/SUCCESS) CGroup: name=systemd:/system/nfs-server.service Warning: Journal has been rotated since unit was started.

• linux to linux, 10TB transfer?

  - by lostincode

  I've looked at all the previous similar questions, but the answers seemed to be all over the place and no one was moving a lot of data (100GB != 10TB). I've got about 10TB that I need to move from one raid to another, gigabit net, XFS file systems. My biggest concern is having the transfer die midway and not being able to resume easily. Speed would be nice, but ensuring transfer is much more important. Normally I'd just tar & netcat, but the raid I'm moving from has been super flaky as of late and I need to be able to recover and resume if it drops mid process. Should I be looking at rsync?

• Good way to run commands on remote computer without its own public-facing IP address (Linux Centos)

  - by Chris Dutrow

  Have a few computers running Linux Centos 6.4. They are connected to an unmanaged switch, which in turn, is connected to a router (Verzion Fios issue). What is a good way to "log in" to one of the computers so that I can run commands? Do I need to use SSH, or something different? Since the computers do not have their own public-facing IP addresses, do I need to set up some kind of port forwarding within the router? What is a simple, reliable way to accomplish this? Thanks so much!

• Changing the mac address in a libvirt xml config file breaks network connectivity for the guest

  - by foob

  I'm using Xen with libvirt and trying to set it up on a bridged interface. I am able to install an OS and everything works as I would expect. If I save the xml output from "virsh dumpxml guest", edit the mac address for the interface, and then define the domU with this new xml file I find that traffic is no longer forwarded from the vif0.0 interface to br0. The ifcfg-eth0 file on the guest was automatically updated to reflect the new mac address and the ifconfig output looks the same. Does anyone know why this is happening or how to properly change the mac address for a libvirt configuration?

• monitor network bandwidth via ssh

  - by ServerSideX

  I'm running a Centos 6.4 server with cPanel. WHM (admin side panel) shows about 100GB of bandwidth this month. However, the server's RTG shows 3.4TB last 30 days, 121GB past 24 hours alone. Doesn't make sense. I'm trying to trace the cause of this. It's a shared web hosting server for approximately 300 domains. I would appreciate help tracing this down somehow. I utilize CSF firewall and Configserver exploit scanner as well. Day http://s10.postimg.org/ti1qhj5mx/day.png Week http://s7.postimg.org/8ho8kds57/week.png

• Virtual guest does not have network access in cafe.

  - by blee

  My Virtualbox guest OS (Ubuntu on ubuntu host) does not connect to the internet when I have wifi access through an internet cafe system. By this, I mean where your browser redirects to an internal web page where you can enter a code. On the guest, I can successfully connect to the virtual network adapter, but I do not get internet access, nor a redirect to the internal web page. I use OpenDNS for the host. I have no problems when connecting through ethernet or regular wifi. Can someone tell me any of: 1) How to fix the problem. 2) How such cafe systems work. 3) At least point me to a technical explanation of such a cafe system so I can begin to troubleshoot. Thanks!

• NFS performance troubleshooting

• tomato firmware unstable when I am connected to Chromecast

  - by Graviton

  I have an Asus RT-N12D1, and I installed the tomato firmware by shibby ( version tomato-K26-1.28.RT-N5x-MIPSR2-112-Max.trx). However I found that the connection can be really unstable. Whenever I stream youtube videos on TV via Chromecast ( I tried both the cast from iPad and Win7, both can reproduce the problem), the router will frequently restart itself, leading to a loss of connection and subsequent reconnection. I want to get this problem fixed, but I don't know how. Is there anyway where I can troubleshoot what is the real problem, or is there anyway I can collect enough log information so that I can then present to the original developer for a fix ( maybe)?

  I have a windows 7 host with firewall turned off. And I have a windowsXP guest running on Virtualbox 4.2.4r81684.

• How to specify what network interface to use with TTCP or IPERF?

  - by Sammy

  The PC has two Gigabit Ethernet ports. They function as two separate network adapters. I'm trying to do a simple loopback test between the two. I've tried TTCP and IPERF. They're giving me hard time because I'm using the same physical PC. Using pcattcp...

• VPN Network intermittantly fails to provide internet: What could be possible causes

  - by Jake M

  We have a small office with our own VPN setup. We occasionally experience failures in our internet connection where we cannot access the internet. Most of the time the internet connection will resume by itself(without me doing anything) after a period of time(10 mins). Would you be able to suggest possible causes of the connection failure so I can then go and run some tests? Our network architecture is like so: A 'Billion' brand router that is connected to the internet via phone cable and then connected to our Cisco Switch A Cisco Switch/Bus which is connected to all our office nodes, our external harddrive and also to our router as stated above. All connections are via ethernet cable A series of work computers(nodes) connected via ethernet cable to the Cisco switch. Our ISP is TPG Australia We have a Virtual Private Network All the ethernet cables are about 3 years old Do you think that the causes of our intermittant connection problems could be due to the following: Data collisions in the ethernet cables Old/Faulty ethernet cables Our ISP has bad service Can you think of any other causes of the problem?

• Using two ports on my ZyXel USG gateway to patch two devices together?

  - by Matthew Beza

  I don't know if this is possible but it would save me many long drives! I have drawn, with my epic MS Paint skills, my current setup. I have a ZyXel USG300 Gateway with a built in 5 port switch. It supports bridging, tunnles, VLANs, etc.. I have a Cisco WLC2112 plugged into port 6 (P6). The cisco is set to 192.168.6.2 and P6 is set to 192.168.6.1. This works but I need to incorporate a Nomadix AG3000 to handle guests. (Router (A) in the picture). So I need the Cisco WLC2112 to use the Nomadix as if it where plugged into it's LAN port. Right now the Nomadix WAN Port is plugged into (P2) on the ZyXel, and the Nomadix LAN port is plugged into (P3). Is it possible to set something up where (P3) and (P6) are somehow "Patched" as if the Cisco was plugged directly into the Nomadix LAN port? Basically making the ZyXel a fancy Cat5e coupler?

• Huawei b260a gsm modem not forwarding gre for pptp tunnel

  - by Priit

  I have a huawei gsm modem that does not want to let gre through. The goal is to connect into a pptp server thats behind the huawei. In the modems port forwarding settings theres a ready made profile for pptp (1723). After activating that the MS pptp test tools show that connection is being initiated but no gre packets make it to the server. After taking a closer look into the modems iptables rules theres nothing in there about gre. So I tried making gre rules manualy into forward and preroute chains without any success what so ever. As far as I can tell theres no ip_gre module present on the device is that needed for gre forwarding? Thats what I'm afraid of that it doesn't support gre in NAT but how would I turn it into a bridge? The wan interface is ppp0 so bridging it with eth0 would not work right? Is there some iptables rule I could use to make the modem let all the traffic just straight through?

• All traffic is passed through OpenVPN although not requested

  - by BFH

  I have a bash script on a Ubuntu box which searches for the fastest openvpn server, connects, and binds one program to the tun0 interface. Unfortunately, all traffic is being passed through the VPN. Does anybody know what's going on? The relevant line follows: openvpn --daemon --config $cfile --auth-user-pass ipvanish.pass --status openvpn-status.log There don't seem to be any entries in iptables when I enter sudo iptables --list. The config files look like this: client dev tun proto tcp remote nyc-a04.ipvanish.com 443 resolv-retry infinite nobind persist-key persist-tun persist-remote-ip ca ca.ipvanish.com.crt tls-remote nyc-a04.ipvanish.com auth-user-pass comp-lzo verb 3 auth SHA256 cipher AES-256-CBC keysize 256 tls-cipher DHE-RSA-AES256-SHA:DHE-DSS-AES256-SHA:AES256-SHA There is nothing in there that would direct everything through tun0, so maybe it's a new vagary of Ubuntu? I don't remember this happening in the past.

• Determining who is running with administrator rights?

  - by Alex C.

  I work at a small non-profit organization with about 55 desktop PCs running Windows XP Pro. The domain controller is running Windows Server 2003. I have a two-part question (note that I'm a bit of a newb when it comes to network administration). Part 1: Is there some simple way that I can determine which accounts are logged in with administrator rights? Part 2: Is there a way that I can remove administrator rights from users without sitting down at each individual machine? Thanks for considering my questions.
