• How to permanently add wireless interfaces with iw

  - by walli

  How can I permanently add virtual wireless interfaces to my network configuration with iw? I created the following interfaces: iw phy phy0 interface add vwlan0 type station iw phy phy0 interface add vwlan1 type __ap The first is configured as a wifi client connecting to an existing network (wpa_supplicant) The second is configured as wireless hotspot (hostapd + dnsmasq) The setup works, but now I can't quite figure out what the best strategy is to save this configuration permanently. Have made an init script for wpa_supplicant Have made an init script for the hotspot Virtual adaptor network settings set in /etc/network/interfaces But all this depends on the wireless interfaces being created. What would be the best way to make sure these interfaces are created before the network is set up and the services are run? As a bonus, since this wireless interface is a usb device, would it be possible to have the interfaces created (and the services started) when the interface is hotplugged? I know you can execute code after a network interface is up, but the wlan0 interface that is hotplugged should never be up. Operating system is raspbian

• Trouble connecting a Ubuntu system to IPv6 tunnel over NAT

  - by John Millikin

  I'm trying to set up an IPv6 tunnel, via Hurricane Electric's tunnel-broker service. I've configured my system using their example commands: # $ipv4a = tunnel server's IPv4 IP # $ipv4b = user's IPv4 IP # $ipv6a = tunnel server's side of point-to-point /64 allocation # $ipv6b = user's side of point-to-point /64 allocation ip tunnel add he-ipv6 mode sit remote $ipv4a local $ipv4b ttl 255 ip link set he-ipv6 up ip addr add $ipv6b dev he-ipv6 ip route add ::/0 dev he-ipv6 And have configured my desktop to be in my NAT router's DMZ. The router is running Tomato firmware. But I can't ping any IPv6 services: $ ping6 -I he-ipv6 '2001:470:1f04:454::1' PING 2001:470:1f04:454::1(2001:470:1f04:454::1) from 2001:470:1f04:454::2 he-ipv6: 56 data bytes From 2001:470:1f04:454::2 icmp_seq=1 Destination unreachable: Address unreachable From 2001:470:1f04:454::2 icmp_seq=2 Destination unreachable: Address unreachable I can ping my local address: $ ping6 -I he-ipv6 '2001:470:1f04:454::2' PING 2001:470:1f04:454::2(2001:470:1f04:454::2) from 2001:470:1f04:454::2 he-ipv6: 56 data bytes 64 bytes from 2001:470:1f04:454::2: icmp_seq=1 ttl=64 time=0.037 ms 64 bytes from 2001:470:1f04:454::2: icmp_seq=2 ttl=64 time=0.039 ms I don't know much about routing, but results I found online suggested the output of ip -6 route and ip addr could be useful: $ ip -6 route 2001:470:1f04:454::/64 via :: dev he-ipv6 proto kernel metric 256 mtu 1480 advmss 1420 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 via :: dev he-ipv6 proto kernel metric 256 mtu 1480 advmss 1420 hoplimit 4294967295 default dev he-ipv6 metric 1024 mtu 1480 advmss 1420 hoplimit 4294967295 $ ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 100 link/ether 00:1c:c0:a1:98:b2 brd ff:ff:ff:ff:ff:ff inet 192.168.1.10/24 brd 192.168.1.255 scope global eth1 inet6 fe80::21c:c0ff:fea1:98b2/64 scope link valid_lft forever preferred_lft forever 3: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 36:4c:33:ab:0d:c6 brd ff:ff:ff:ff:ff:ff inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0 inet6 fe80::344c:33ff:feab:dc6/64 scope link valid_lft forever preferred_lft forever 4: vboxnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 00:76:62:6e:65:74 brd ff:ff:ff:ff:ff:ff 5: pan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN link/ether 7e:29:5e:7c:ba:93 brd ff:ff:ff:ff:ff:ff 6: sit0: <NOARP> mtu 1480 qdisc noop state DOWN link/sit 0.0.0.0 brd 0.0.0.0 7: he-ipv6@NONE: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN link/sit 24.130.225.239 peer 72.52.104.74 inet6 2001:470:1f04:454::2/64 scope global valid_lft forever preferred_lft forever inet6 fe80::1882:e1ef/128 scope link valid_lft forever preferred_lft forever

• What's wrong with my custom patch cables?

  - by stu42j

  I have a box of bulk Cat5e riser cable left over from when I had my house wired. I figured I could use this to make some custom length cables for connecting my computers, switches, etc. I had a crimper already so I bought a bag of RJ45 plugs. I made a few cables several years ago, but my experience/knowledge with this sort of thing is minimal. None of my cables are working. I don't have a tester so I just plug the cable into a computer and switch but I get no link light. I wired them them all straight-through and visual inspection doesn't show any problems. Any ideas what I might be doing wrong?

• Sonicwall routing between multiple subnets on multiple interfaces

  - by Rain

  As shown by the network diagram below, I have two completely separate networks. One is being managed by a Sonicwall NSA 220, the other by some other router (the brand is not important). My goal is to allow devices within the 192.168.2.0/24 network to access devices in the 192.168.3.0/24 network. Allowing the reverse (192.168.3.0/24 - 192.168.2.0/24) is not required. So far, I have done the following: I connected the X3 Interface on the Sonicwall to the 192.168.3.0/24 network switch (shown as the dashed red line in the diagram). Next, I gave it a static ip address of 192.168.3.254 and set the Zone to LAN (the same Zone for the X0 interface). Judging by various articles and KBs I've read, this is all that should be necessary, although it does not work. I can ping 192.168.3.254 from any device in the 192.168.2.0/24 network although I cannot ping/connect to any device within the 192.168.3.0/24 network. Any help would be greatly appreciated! Network Diagram: (I asked a similar, yet more complicated, question earlier; although, I realized that I cannot solve that without first solving this (which may actually solve my original question))

• Changing default gateway on workstations connected to Windows Domain SBS server

  - by Gary B2312321321

  We have xp workstations connected onto a small business server acting as active directory/isa firewall/proxy (no dhcp). Is there a reason that after installing a 2nd firewall on the network (same subnet etc), that changing the default gateway on the workstations isnt sufficient to route inet traffic through the new firewall? A freshly setup linux box connects straight on to the alternate firewall with just ip, default gateway. dns settings. Will having ISA still active on the network confuse the process? Are there further config settings deeper down in windows that need attention? Any ideas pointers on this would be appreciated? Other info: Firewalls tried: Smoothwall and Ipcop; small ethernet netwoork 40 pcs; can ping to new firwalls from workstations; activating web proxy on new firewall and reconfiguring workstation browser works fine; Point of 2nd firewall is lack of some necessary features on ISA for a linux app; Would be nice to have some redundancy to though

• iPod touch has extremely slow wifi, drops packets - only on my router

  - by mskfisher

  I just purchased an iPod Touch. I am having a lot of trouble with its speeds on my Tenda W311R, but it has no speed problems on my neighbor's Netgear router. It will connect and authenticate to my network, but the Speed Test app from speedtest.net shows rates near 20-50 kbps. If I run the speed test immediately after powering the iPod on, it will get speeds of 10-20 Mbps, like it should - but the speeds slow down to the kbps range abut 10-15 seconds afterward. I get the same behavior with encryption and without encryption, and regardless of N, G, or B compatibility settings in the router. I've tried rebooting the iPod and resetting the network settings, but it's still slow. I've tried pinging the iPod from another computer, and it shows about 40% packet loss: $ ping 192.168.0.111 PING 192.168.0.111 (192.168.0.111): 56 data bytes 64 bytes from 192.168.0.111: icmp_seq=0 ttl=64 time=14.188 ms 64 bytes from 192.168.0.111: icmp_seq=1 ttl=64 time=11.556 ms 64 bytes from 192.168.0.111: icmp_seq=2 ttl=64 time=5.675 ms 64 bytes from 192.168.0.111: icmp_seq=3 ttl=64 time=5.721 ms Request timeout for icmp_seq 4 64 bytes from 192.168.0.111: icmp_seq=5 ttl=64 time=6.491 ms Request timeout for icmp_seq 6 64 bytes from 192.168.0.111: icmp_seq=7 ttl=64 time=8.065 ms Request timeout for icmp_seq 8 Request timeout for icmp_seq 9 Request timeout for icmp_seq 10 64 bytes from 192.168.0.111: icmp_seq=11 ttl=64 time=9.605 ms Signal strength is good - I'm never more than 20 feet from my access point, and it exhibits the same behavior if I'm standing next to the router. It works just well enough to receive text, but videos don't work at all. App downloads are hit and miss. I've tweaked just about all of the settings I can see to tweak, and I'm at a loss. I have also been searching Google for the past three days, all to no avail. Any suggestions?

• Wireless Network Issue, Disconnecting Randomly From Network

  - by Surfer513

  I'm having an odd problem with my wireless network. Here is the background information: Server (Windows Server 2008) 1 to 10 end user machines connecting to the network Layer 3 Access Point (Asus WL-330 gE) connected to ethernet of Server and all machines connect to the network via the AP The end user machines get a connection to the server with no problems initially. But then connections are randomly lost throughout the day to the server/network. The wireless NICs of the machines still see the wireless network but are unable to connect to it. Then after some time the connection is regained automatically. I initially thought there was a problem with this particular AP, but then I took the same make/model AP out of storage and still ran into the problem. Any ideas what could be causing this??? Very confusing that the wireless nics on the end user machines can still see the network but not connect, and that the connections are randomly lost/gained. Thanks in advance!

• Setup IPsec VPN using ASA5505 behind Juniper SSG5

  - by i_ch3ry

  I have been assigned to establish a Internet IPsecVPN connection between two sites using Cisco ASA5505 A site currently has following setup.(Same setup is expected in another site) Internet-----ADSL Router-----Juniper SSG5-----Intranet (Im not sure what is configured on SSG5 and if router is in bridge mode or if NAT is configured) I was thinking if I should install ASA5505 along with Juniper SSG5? Internet-----ADSL Router-----Juniper SSG5-----Cisco ASA5505(for vpn only)------Intranet or Internet-----ADSL Router-----Cisco ASA5505(for vpn only)-----Juniper SSG5------Intranet My question is if it is possible? What should be the normal way to achieve this goal? Thanks

• Visualization Tools for Networks that Change with Time

  - by devin

  Does anyone known of any good Linux tools for visualizing networks that change (quickly) with time. I'm interested in things like: Routes between nodes Delays between nodes (especially as they change with time) Throughput I have root access to all the nodes (so I can run daemons on them all). Also, assume that I either have a management network that is stable or I will collect data and then analyze it offline.

• Problem with switch dell 6224

  - by Matias

  Hello, we just have upgraded the firmware of a dell 6224 power connect switch and it won't reload. These are the symptons: - I power up the switch having the serial cable connected to it and the switch outputs nothing. The configuration of the serial console is fine: 9600 bds, etc... In fact, before the upgrade, I was connected to the switch through the very same cable. - Reseting the switch with its reset pinhole does not reset the switch: the power and fan lights powers off while I keep pressed the pinhole, but the switch itself does not resets. - When I connect an UTP cable to one of the switches port, the green lights don't flash, but ''mii-tool eth0'' in my laptop shows there is link!! The only thing I see in the output, different from other upgrades I've done, is this line at the end: Erasing Boot Flash.....^^^^Done. Any help or idea will be more than welcome!! Thanks!! console#show version Image Descriptions image1 : image2 : Images currently available on Flash -------------------------------------------------------------------- unit image1 image2 current-active next-active 1 <none> 3.0.0.8 image2 image2 console#boot system image2 Activating image image2 .. console#update bootcode Update bootcode and reset (Y/N)?

• VMware Fusion configuration files missing

  - by jdmuys

  I need to set up port forwarding to my VM in Fusion 5. Everywhere on the net, the solution is described as editing the file: /Library/Application Support/VMware Fusion/vmnet8/nat.conf However, on my install, that file doesn't exist. Neither does the vmnet8 directory. Here is the full content of VMware stuff I have in /Library/Application Support/: /Library/Application Support/ VMware/ VMware Fusion AdminWritable Shared vmInventory usbarb.rules VMware Fusion That's right: /Library/Application Support/VMware Fusion/ exists but is empty. And there is no VMware folder in other Library directories on my system. I am running OS X 10.8.2. I just reinstalled Fusion 5.02, no change. Meanwhile, I have 3 VMs that work just fine. So how am I supposed to set up port forwarding with Fusion 5? Thanks, JD Edit: in a hunch, I tried ps ax | grep natd which returned: 9646 ?? S 0:00.01 /Applications/VMware Fusion.app/Contents/Library/vmnet-natd -s 7 -m /Library/Preferences/VMware Fusion/vmnet8/nat.mac -c /Library/Preferences/VMware Fusion/vmnet8/nat.conf So it seems that the configurations files are now in the directory /Library/Preferences/VMware Fusion. I'll work from here and edit this question as I make progress.

• Linux pptp client stops working after several hours

  - by Aron Rotteveel

  Here's the situation: Setup: 1 Windows Server 2008 machine acting as a Domain Controller and RRAS server 1 CentOS machine in a datacentre located elsewhere PPTP client running on CentOS machine, connected to the DC via When I connect to the DC, everything is working fine. I have set up a static IP for the dialup connection in my RRAS server so that the CentOS machine is automatically assigned the IP 192.168.1.240. Inside the VPN, it is not possible to access this machine on the local IP-address. Perfect. However, after several hours, it simply seems to stop working (IE: I cannot ping to or from this machine on the local network). The strange thing is, however: The DC shows the VPN client as still being connected The CentOS machine shows the network interface as being up There are no entries in my /var/log/messages that indicate a problem Output from ifconfig: ppp0 Link encap:Point-to-Point Protocol inet addr:192.168.1.240 P-t-P:192.168.1.160 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1396 Metric:1 RX packets:43 errors:0 dropped:0 overruns:0 frame:0 TX packets:58 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:4511 (4.4 KiB) TX bytes:15071 (14.7 KiB) Output from route -n: 192.168.1.160 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 ppp0 I have the following in my ip-up.local: route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0 The situation can be easily fixed by issueing a killall pppd and re-connecting.

• Server 2008 print server down / access denied

  - by johnnyb10

  I have two Server 2008 servers (both running as VMs in VMware). One is a Full Installation, and the other is a Server Core installation. I just installed Print Services on both of them. In Print Management on the Full server, I added the Server Core print server (so now two print servers are listed in Print Management). However, the icon for my Server Core print server has a red, down-pointing arrow (indicating that it is down, I suppose). And when I right-click it and click Add Printer, I get a message saying that access is denied. Can someone tell me how to bring up or check on the status of the Server Core print server. Obviously, I'm somewhat of a noob with this stuff. Thanks in advance...

• Setup LAN to serve webpages and voip and access to the web site from inside LAN with domain name

  - by Mauricio Arias

  I'd like to know if it will work: I have my domain and I´m serving a webpage in a nginx to the internet, but if I type my domain in my laptop inside LAN I access to my modem/router configuration, I cannot access to the web server unless I type the IP address. I would like to add a Bind server after the modem/router - (port forward, ports 80 and 5060), if the request is www.mydomain.com bind should resolve the nginx IP address and serve it, and if it is a voip request should address to the voip server and if I'd like to access to the website from inside LAN I'd like to type mydomain.com. Could I do it with this configuration? Do I need something else? Thanks in advace!

• Why does my macbook pro have long ping times over wifi?

  - by randynov

  I have been having problems connecting with my wifi. It is weird, the ping times to the router (<30 feet away) seem to surge, often getting over 10s before slowly coming back down. You can see the trend below. I'm on a macbook pro and have done the normal stuff (reset the pram and smc, changed wireless channels, etc.). It happens across different routers, so I think it must be my laptop, but I don't know what it could be. The RSSI value hovers around -57, but I've seen the transmit rate flip between 0, 48 & 54. The signal strength is ~60% with 9% noise. Currently, there are 17 other wireless networks in range, but only one in the same channel. 1 - How can I figure out what's going on? 2 - How can I correct the situation? TIA!

• Windows user account just for accessing network shares on a Windows 7 machine

  - by Paulo

  I would like my Xbox (Xbmc) to access my Windows 7 shares without having Guest accounts enabled and without using my Administrator account login details. I have tried making it an account called Xbox and this works fine but the Xbox account appears on the login page for Windows. Is there a way to create an account that is purely for accessing shares without it appearing as a user account????

• Unable to connect to Adobe Connect

  - by ub3rst4r

  I am having troubles trying to connect my colleges Adobe Connect. I have done the test meeting connection and it will say "Unable to connect". I have tried connecting on 3 other computers and it works with flying colors. I am running Norton 360 on my computer and I also tried it on my other laptop thats also running Norton 360 and it works on that laptop. I also checked my hosts file and that is not the problem because I am able to connect to the server (on port 80) but not the Adobe Connect port (port 1935). The only thing in it is "127.0.0.1 localhost" Here are the details from the log that the test created: Player Version: WIN 11,3,300,271 App-Server returned: code:ok, servers=rtmp://connect.bowvalleycollege.ca:1935/_rtmp://localhost:8506/,rtmpt://connect.bowvalleycollege.ca:443/_rtmp://localhost:8506/ ERROR: FMS Server did not return correctly! Here is my specifications: Windows 7 SP1 x64 Norton 360 v6.3 (latest) It won't connect in Firefox v15, Chrome v19, or IE9 All of my computers are connected through the same router (D-Link DIR-625) Any ideas?

• Configuring VLAN's on two HP procurve switches

  - by pan

  Trying to route a new ISP (Microwave link) from one of my out buildings to my computer room and hence my firewall. Old ISP came direct into firewall. In the outbuilding the Microwave modem connects with cat5 to HP Procurve 2524 switch. Because this ISP is coming through my internal network, I plan on using a new vlan called "airspeed" only for this ISP traffic. Up until now I've just been using the Default_vlan on both HP switches (4108 + 2524). So far I've been unable to ping from my laptop to the ISP modem both of which are on the new vlan 2 ("Airspeed"). No traffic needs to cross from vlan 2 to vlan 1 so I've left the ports as untagged. I've used the subnet provide from my ISP as the new vlan 2 subnet. Can anybody see what I'm doing wrong here? I've added the configuration of both switch below. Rough diagram: Microwave modem (Gateway IP 77.75.00.49) | HP 2524 switch (port 24) | HP 2524 switch fibre link | HP 4108GL switch fibre link | HP 4108GL switch (port D1) | Laptop configured with IP 77.75.00.50 (for testing but will be connected to firewall) And my 4108GL config: ; J4865A Configuration Editor; Created on release #G.07.21 hostname "HP ProCurve Switch 4108GL" cdp run module 1 type J4864A module 2 type J4862B module 3 type J4862B module 4 type J4862B ip default-gateway 128.1.146.50 snmp-server community "public" Unrestricted snmp-server host 128.1.146.51 "public" Not-INFO snmp-server host 128.1.146.38 "public" vlan 1 name "DEFAULT_VLAN" untagged A1-A3,B1-B24,C1-C24,D2-D24 ip address 128.1.146.203 255.255.0.0 no untagged D1 exit vlan 2 name "Airspeed" untagged D1 ip address 77.75.00.51 255.255.255.248 exit Finally my 2524 config: ; J4813A Configuration Editor; Created on release #F.04.08 hostname "HP ProCurve Switch 2524" cdp run ip default-gateway 0.0.0.0 snmp-server community "public" Unrestricted snmp-server host 128.1.146.51 "public" Not-INFO snmp-server host 128.1.146.51 "public" snmp-server host 128.1.146.38 "public" vlan 1 name "DEFAULT_VLAN" untagged 1-23,25-26 no untagged 24 ip address 128.1.146.204 255.255.0.0 exit vlan 2 name "Airspeed" untagged 24 ip address 77.75.00.51 255.255.255.248 exit no aaa port-access authenticator active

• Network Logon Issues with Group Policy and Network

  - by bobloki

  I am gravely in need of your help and assistance. We have a problem with our logon and startup to our Windows 7 Enterprise system. We have more than 3000 Windows Desktops situated in roughly 20+ buildings around campus. Almost every computer on campus has the problem that I will be describing. I have spent over one month peering over etl files from Windows Performance Analyzer (A great product) and hundreds of thousands of event logs. I come to you today humbled that I could not figure this out. The problem as simply put our logon times are extremely long. An average first time logon is roughly 2-10 minutes depending on the software installed. All computers are Windows 7, the oldest computers being 5 years old. Startup times on various computers range from good (1-2 minutes) to very bad (5-60). Our second time logons range from 30 seconds to 4 minutes. We have a gigabit connection between each computer on the network. We have 5 domain controllers which also double as our DNS servers. Initial testing led us to believe that this was a software problem. So I spent a few days testing machines only to find inconsistent results from the etl files from xperfview. Each subset of computers on campus had a different subset of software issues, none seeming to interfere with logon just startup. So I started looking at our group policy and located some very interesting event ID’s. Group Policy 1129: The processing of Group Policy failed because of lack of network connectivity to a domain controller. Group Policy 1055: The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one of more of the following: a) Name Resolution failure on the current domain controller. b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller). NETLOGON 5719 : This computer was not able to set up a secure session with a domain controller in domain OURDOMAIN due to the following: There are currently no logon servers available to service the logon request. This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator. E1kexpress 27: Intel®82567LM-3 Gigabit Network Connection – Network link is disconnected. NetBT 4300 – The driver could not be created. WMI 10 - Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected. More or less with timestamps it becomes apparent that the network maybe the issue. 1:25:57 - Group Policy is trying to discover the domain controller information 1:25:57 - The network link has been disconnected 1:25:58 - The processing of Group Policy failed because of lack of network connectivity to a domain controller.
