• No icons in top panel notification area

  - by PeterOakland

  (writing here because my reply to a previous post is marked "deleted by diago") Ubuntu 9.10 Karmic I have tried removing the notification area from the top panel and reinstalling it, and still I have nothing in it: no volume control, no connection icon. I have put a notification area on the bottom panel, and the only icon appearing is the connection one, looks like two plugs meeting, or a large resistor in line, or two toilet plungers face to face, so to speak. How can I get this up top where it used to be, along with the volume control icon? Thanks for any help.

• Can I alias all directory requests to a single file in nginx?

  - by user749618

  I'm trying to figure out how to take all requests made to a particular directory and return a json string without a redirect, in nginx. Example: curl -i http://example.com/api/call1/ Expected result: HTTP/1.1 200 OK Accept-Ranges: bytes Content-Type: application/json Date: Fri, 13 Apr 2012 23:48:21 GMT Last-Modified: Fri, 13 Apr 2012 22:58:56 GMT Server: nginx X-UA-Compatible: IE=Edge,chrome=1 Content-Length: 38 Connection: keep-alive {"logout": true} Here's what I have so far in my nginx conf: location ~ ^/api/(.*)$ { index /api_logout.json; alias /path/to/file/api_logout.json; types { } default_type "application/json; charset=utf-8"; break; } However, when I try to make the request the Content-Type doesn't stick: $ curl -i http://example.com/api/call1/ HTTP/1.1 200 OK Accept-Ranges: bytes Content-Type: application/octet-stream Date: Fri, 13 Apr 2012 23:48:21 GMT Last-Modified: Fri, 13 Apr 2012 22:58:56 GMT Server: nginx X-UA-Compatible: IE=Edge,chrome=1 Content-Length: 38 Connection: keep-alive {"logout": true} Is there a better way to do this? How can I get the application/json type to stick?

• Windows 7 port Forwarding Issue

  - by Elliot

  I can't get port forwarding to work now that I am using windows 7 (64-bit). I am using a wireless connection (no wired connection available). I have the ports forwarded (IP has been double checked, router settings are confirmed), there is an exception for all of the programs in question in windows firewall, and in the resource monitor windows lists the ports as available, not restricted, and yet when I either use a specific program (ie utorrent, DC++, Command & Conquer 3) or check using firefox, the port reads as closed. How do I get the port forwarding to work?

• TIME_WAIT connections not being cleaned up after timeout period expires

  - by Mark Dawson

  I am stress testing one of my servers by hitting it with a constant stream of new network connections, the tcp_fin_timeout is set to 60, so if I send a constant stream of something like 100 requests per second, I would expect to see a rolling average of 6000 (60 * 100) connections in a TIME_WAIT state, this is happening, but looking in netstat (using -o) to see the timers, I see connections like: TIME_WAIT timewait (0.00/0/0) where their timeout has expired but the connection is still hanging around, I then eventually run out of connections. Anyone know why these connections don't get cleaned up? If I stop creating new connections they do eventually disappear but while I am constantly creating new connections they don't, seems like the kernel isn't getting chance to clean them up? Is there some other config options I need to set to remove the connections as soon as they have expired? The server is running Ubuntu and my web server is nginx. Also it has iptables with connection tracking, not sure if that would cause these TIME_WAIT connections to live on. Thanks Mark.

• Ubuntu not connecting to network in Hyper-V

  - by soandos

  I am unable to connect the Ubuntu guest (both 12.10 and 12.04) to the internet via hyper-V. Here is what I have done so far (with much thanks due to @Kronos's blog post on the topic): Created a switch in the switch manager with connection set to external, selected my wifi card (Intel Centrino Ultimate-N 6300 AGN). If it matters, the Microsoft Filtering Platform is checked under extensions. Added this switch to my Ubuntu guest. I also tried a different wireless card (Aethros 9285) same issue. Connecting through my wired card works just fine (assume that I select that card, and I am wired in of course). Making it a legacy network adapter does not fix the issue. Ubuntu can see this connection, but is unable to connect to it. What follows is what I attempted to do to get Ubuntu to connect: Start and restart the network manager Restart the machine Verify that it could in fact see the adapter (resulted in device not ready a few times) How can I get this to work properly?

• Wireless Access Point - Can't ping other machines on the wireless network

  - by Surfer513

  I have a wireless access point (Netgear), and I have it setup so that it has an IP address in the current subnet (let's say 192.168.2.0, subnet mask of 255.255.255.0). The machine that it is connected to via ethernet cable has an IP in the same subnet as the AP. The machines that are connected to the AP via the wireless connection also have an IP address in the same subnet as the rest of the network (192.168.2.0). All machines can ping the access point, but they cannot ping each other. I don't totally understand why, because there is connection and all of the machines are in the same subnet. I realize this is a layer 3 device, but is there an issue because of this AP's lack of gateway capabilities? (i.e. no routing table, etc.)

• Question about Remote WAN IP on NetGear FVS336G VPN setup

  - by camilian

  I wanted to be able to have a VPN connection to my home network so I purchased the FVS336G because the reviews said it was easy set up. I am sure it is for someone that knows what needs to be entered it is easy, but I am a little confused. Using the VPN wizard I choose VPN Client as the tunnel connection, enter key, etc... but then I get to the "What is the remote WAN's IP or Internet Name" and "What is the local WAN's IP address or Internet Name" I am lost. I am probably being really dumb, but I am not sure what I need to put in here. Is the remote WAN ip the ip from the outside world to my cable modem? Is the local ip the ip to my FVS336G? Any help would be appreciated.

• What are the steps to set up a Hyper-V solution with one NIC

  - by Cameron Aziz

  I have successfully installed centos on a virtual machine via Hyper-V on Windows Server 2008 R2. This server has one NIC. I have created a virtual NIC, and virtual subnet, and within the virtual machine (via console) I can ping the gateway. But not google. Is there certain steps I am missing, I feel like I'm one setting away. Im not sure what other information would be useful. Here is the ipconfig of the host: Ethernet adapter vNIC losangeles1_1: Connection-specific DNS Suffix .. : IPv4 Address. . . . . . . . . . . : 10.10.0.1 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : Ethernet adapter Local Area Connection 2: Connection-specific DNS Suffix .. : IPv4 Address. . . . . . . . . . . : 72.51.43.43 Subnet Mask . . . . . . . . . . . : 255.255.255.192 Default Gateway . . . . . . . . . : 72.51.43.1

• Network bottleneck/throttling issue

  - by Gavin

  Hi all, It's my first day at a new company and i've been given the task to find out an issue with the internet connection. I noticed that whilst I was downloading a large file, the network grinds to a halt, except for my download. At first I thought it was the internet connection/modem but it seems that whilst the lockdown occurs, I am unable to access any network device. Has anyone experienced this before and if so, do you have any pointers? Looking at the setup. They have an DSL modem that connects to a 10/100 switch. There are only 5-6 computers on the network. Cheers Gavin

• dpkg E: Sub-process /usr/bin/dpkg returned an error

  - by user81269

  I decided to shift around my partitions on my hard drive for a fresh install of Kubuntu. I booted my Ubuntu 10.10 live disc, shifted everything around and attempted to install grub and it didn't work, so I burnt an Ubuntu 12.04 disc and installed it. I got the computer working and wanted to install some packages, but didn't have an internet connection at the time. So (I know this was stupid) I got some debs from previous versions of Ubuntu, as I needed my music, and the other install took a long of time to boot. Once I got my internet connection back, everything worked ok, for a little while. Then I stumbled upon this problem after removing ten broken packages using synaptic: drhax@Spamotard:~$ sudo apt-get install -f Reading package lists...

• Some DHCP clients end up with wrong DNS server

  - by Nic Waller

  The scenario: DC running Windows Server 2008 R2 providing DNS + DHCP Cisco 1811 Router as the gateway 30 Windows XP DHCP clients on the LAN The problem: Some workstations are spontaneously switching to an incorrect DNS server. Specifically, ipconfig /all shows that they start using the gateway as a DNS server. This happens about 5-10 times a day to various computers, sometimes more than once per day. The workaround: Repairing the connection on the XP client always fixes the problem, and the correct DNS server address is obtained. We lost our main DNS/DHCP machine a week ago, and had to bring this one online as a spare. We've been having this issue since then. DHCP leases on the old and new servers are configured for "wired" (8 day) duration. There are definitely no other DHCP servers active on the LAN. So far there is no discernible pattern about which clients will show this problem, or when. When I ran DCDIAG /test:DNS it came back clean. Manual inspection of the DNS zone shows that all the records are appearing as expected, with no traces of the previous machine in there. Update Feb 27: Added screenshots. Here is a screenshot of the DHCP scope options on the 2008 R2 server. And here is a screenshot of ipconfig /all running on a healthy host. I don't have any ailing hosts at the moment, but will grab a screencap next time it happens. Update Feb 28: More screenshots. Here's a screenshot of DHCP and DNS traffic from a healthy client when repairing the local area connection. There's definitely only one server responding, but it does seem strange that the negotiation takes place twice. I'll try to get a similar capture from a sick machine this coming week. Update Mar 01: Caught a bad ipconfig. Here's a screenshot of ipconfig /all from a client that had this issue. It says the lease was issued this morning, but it doesn't even have an entry for the secondary DNS I set up yesterday. Both DNS servers were discovered properly when repairing the connection. Update Mar 01: It even got the sysadmin! This issue finally affected my personal workstation this morning. Unfortunately I had just rebooted and wasn't running a packet dump at the time. I set up a secondary server yesterday, and was logging all DNS traffic to it. My machine had not contacted the secondary DNS in over half an hour, so that says to me that it's just spontaneously reverting to the gateway without even failing over to secondary DNS first. Today I swapped the order of the DNS servers in DHCP, so the secondary is primary and vice versa. I will update again once I know how that goes.

• Linksys WRT54G2 not showing connected PC's in DHCP table

  - by Moose

  For some reason all of a sudden my linksys WRT54G2 no longer shows PC's connected in the DHCP table. It was being touchy then all of a sudden they all just disappeared. It showed 2 of the 4 connected then it showed the other 2 then it only showed 1 and then it was showing none. I seem to be having a connection reset every 30-60 minutes also not sure if that is related to the router going bad or if it is just comcast being it's typical crappy self. I have tried to reset my router and my cable modem and both problems still seem to keep happening(no PC's in table and connection reset every 30-60 mins). Now I know the router doesn't store clients after a router reboot but they normally show up within a matter of minutes for me in the past. Before anyone asks yes all devices on the network are using DHCP and not static. Could this be a sign of the router starting to go bad?

• intermittent DNS problems

  - by jemminger

  How would I go about tracking this issue down? One of my websites has been up for years without issue. We're using Godaddy's nameservers for our domain. Lately in the past two weeks, I've noticed that once from home on my Cox cable connection, I could not connect to the site... it said the domain could not be resolved. I checked downforeveryoneorjustme.com, and it said it was fine. The "outage" lasted maybe five minutes (through a reboot too, and I'm on a mac FWIW) and then it started working again. Then it happened again this week, but from our office on a different Cox connection. Then it happened again from the office, but for a different domain. I called Cox during one outage, and the tech there could resolve the domain without a problem. When these outages are occurring, I can issue "host mydomain.com" and get "domain not found", but using "host mydomain.com 8.8.8.8" will resolve normally. Where do I start? We're getting reports now that our customers are experiencing it too.

• how to connect only ethernet and only wireless hosts together

  - by Ashok Das

  Here is my problem. I have an android tablet that have only WiFi for network connectivity and I have a windows server that have only Ethernet ports for network connection. Now I want to telnet to my server from my tablet. I think some wireless to Ethernet converter required in between. I am planning to use Buffalo Air Station WCR-GN or TP-LINK TL-WR740N or TL-WR702N. The connection setup should be like this: [server]<---Ethernet---[WIFI router]<---wireless---[Tablet]. Now I am in doubt will this setup work? Anybody please help me with this. Regards Ashok

• Wireless networking on Gnome on Ubuntu 9 / 10

  - by WaveyDavey

  So here's my problem: I have some netbooks (ASUS eee, and ACER Aspire Ones) that I've been tasked to set up as kiosk machines, locked up tight for normal users. I am a command-line, server man, so this gnome malarkey is all a bit new to me. I found a lovely 9.04 kiosk livecd that installs and runs exactly as I want it to, but I can't get the wireless working. So I dropped on a full 10.4 distro, and wireless works straight out of the box (so hardware is good) - all I needed to do was right-click on the network connection icon, enter my SSID and password (WPA/WPA2) and away it went, perfect. Further investigation on 10.4 distro shows that /etc/networking/interfaces is virtually empty (just auto lo iface lo inet loopback in it), even after I have set up the wireless thru the gnome taskbar applet (is that the right word?). So where does gnome / ubuntu store the network settings to bring the blasted wireless connection up, and what do I need to do on the kiosk version to get wireless running?

• Wi-Fi performance in Windows 8 RP on a MacBook Air (mid 2011)

  - by Steven Lu

  I was able to install the Boot Camp Windows software using the executable that it provided, and there are no unrecognized or unknown devices in Device Manager. Wi-Fi works but it seems to be limited to an extremely slow 1.5Mbits. Network Center reports an 802.11n connection (at 65Mbps usually) but transfers never reach above about 200kB/s. Being limited to 1/20th of the connection speed of my internet service is quite frustrating. Does anybody experience the same issue? I have been trying to identify the Broadcom Wi-Fi chipset and a driver that I could try to upgrade to but I have made very little progress on Google on this front.

• USB ports causing Wireless and Mobile Phone tethering drop out

  - by chrolli

  I have a problem with my USB ports and I can't seem to pinpoint the problem. I'm hoping that I can get some idea as to how to troubleshoot my problem. Problem description: I recently bought a USB Wireless Adapter in order to connect my Desktop PC to the WLAN. The dongle keeps dropping off connection regularly on average once a minute. And the connection is slow. What I've tried: I installed a network scanner to determine signal strength. The PC/adapter combo is getting about 70% signal strength. I have a laptop that has an internal Wireless adapter. I moved the laptop near the location of the PC. The signal strength was above 90%. I installed the USB adapter on the laptop. I placed the laptop near the location of the PC. The signal strength was above 80%. And there is no drop out issue. I've isolated the problem to be on the PC. I used internet tethering on my mobile phone in order to test the USB ports. I get the same problem, themobile phone keeps dropping in and out. I plugged the adapter and phone on all USB ports, and it is still dropping out on all ports. I've isolated the problem to be the Motherboard, USB hub. I updated the BIOS, and USB driver. Still dropping out. I noticed that when I used the mobile phone tethering method, the phone (iphone 5) is guarenteed to drop out and does not appear to charge if I jiggle the the 8-pin connector on the base of the phone. If I push the pin tightly on the phone, the phone starts charging, as soon as I let go, it stops and drops out from the PC. This is strange because this doesn't happen when it is plugged to the powerboard. Which means that the 8 pin connector is fine. I'm not sure what the problem is. I assume that it is to do with the USB ports not supplying enough power which in turn causes the devices to intermittently drop out. The reason I say this is because the USB cable works fine when plugged into a powerboard with enough power supplied to the phone. Only when it is plugged into the USB port on the PC, does it drop out. My motherboard is Asus P8z68-v le. My Wireless adapter is the D-link DWA131. I can't seem to find any settings in the BIOS to increase the south bridge voltage so as to supply more power to the USB ports. Although this problem only occurs when I'm trying to hook up to a device supplying internet connection. My USB HDD, Flash drives, and Mouse and Key are working fine! Any suggestions please?

• Algorithm to Find the Aggregate Mass of "Granola Bar"-Like Structures?

  - by Stuart Robbins

  I'm a planetary science researcher and one project I'm working on is N-body simulations of Saturn's rings. The goal of this particular study is to watch as particles clump together under their own self-gravity and measure the aggregate mass of the clumps versus the mean velocity of all particles in the cell. We're trying to figure out if this can explain some observations made by the Cassini spacecraft during the Saturnian summer solstice when large structures were seen casting shadows on the nearly edge-on rings. Below is a screenshot of what any given timestep looks like. (Each particle is 2 m in diameter and the simulation cell itself is around 700 m across.) The code I'm using already spits out the mean velocity at every timestep. What I need to do is figure out a way to determine the mass of particles in the clumps and NOT the stray particles between them. I know every particle's position, mass, size, etc., but I don't know easily that, say, particles 30,000-40,000 along with 102,000-105,000 make up one strand that to the human eye is obvious. So, the algorithm I need to write would need to be a code with as few user-entered parameters as possible (for replicability and objectivity) that would go through all the particle positions, figure out what particles belong to clumps, and then calculate the mass. It would be great if it could do it for "each" clump/strand as opposed to everything over the cell, but I don't think I actually need it to separate them out. The only thing I was thinking of was doing some sort of N2 distance calculation where I'd calculate the distance between every particle and if, say, the closest 100 particles were within a certain distance, then that particle would be considered part of a cluster. But that seems pretty sloppy and I was hoping that you CS folks and programmers might know of a more elegant solution? Edited with My Solution: What I did was to take a sort of nearest-neighbor / cluster approach and do the quick-n-dirty N2 implementation first. So, take every particle, calculate distance to all other particles, and the threshold for in a cluster or not was whether there were N particles within d distance (two parameters that have to be set a priori, unfortunately, but as was said by some responses/comments, I wasn't going to get away with not having some of those). I then sped it up by not sorting distances but simply doing an order N search and increment a counter for the particles within d, and that sped stuff up by a factor of 6. Then I added a "stupid programmer's tree" (because I know next to nothing about tree codes). I divide up the simulation cell into a set number of grids (best results when grid size ˜7 d) where the main grid lines up with the cell, one grid is offset by half in x and y, and the other two are offset by 1/4 in ±x and ±y. The code then divides particles into the grids, then each particle N only has to have distances calculated to the other particles in that cell. Theoretically, if this were a real tree, I should get order N*log(N) as opposed to N2 speeds. I got somewhere between the two, where for a 50,000-particle sub-set I got a 17x increase in speed, and for a 150,000-particle cell, I got a 38x increase in speed. 12 seconds for the first, 53 seconds for the second, 460 seconds for a 500,000-particle cell. Those are comparable speeds to how long the code takes to run the simulation 1 timestep forward, so that's reasonable at this point. Oh -- and it's fully threaded, so it'll take as many processors as I can throw at it.

  I'm trying to connect to a server but if i use any other user than root the connection closes itself after a successful login: XXXXXXX:~ user$ ssh -v [email protected] OpenSSH_5.2p1, OpenSSL 0.9.8l 5 Nov 2009 debug1: Reading configuration data /etc/ssh_config debug1: Connecting to XXXXXXX.XXXXXX.XXX [xxx.xxx.xxx.xxx] port 22. debug1: Connection established. debug1: identity file /Users/user/.ssh/identity type -1 debug1: identity file /Users/user/.ssh/id_rsa type -1 debug1: identity file /Users/user/.ssh/id_dsa type 2 debug1: Remote protocol version 2.0, remote software version OpenSSH_4.3 debug1: match: OpenSSH_4.3 pat OpenSSH_4* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.2 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host 'XXXXXXX.XXXXXX.XXX' is known and matches the RSA host key. debug1: Found key in /Users/user/.ssh/known_hosts:12 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Next authentication method: publickey debug1: Offering public key: /Users/user/.ssh/woo_openssh debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Offering public key: /Users/user/.ssh/sidlee.dsa debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Trying private key: /Users/user/.ssh/identity debug1: Trying private key: /Users/user/.ssh/id_rsa debug1: Offering public key: /Users/user/.ssh/id_dsa debug1: Authentications that can continue: publickey,gssapi-with-mic,password debug1: Next authentication method: password [email protected]'s password: debug1: Authentication succeeded (password). debug1: channel 0: new [client-session] debug1: Entering interactive session.

I've added the users i want to log in with to a group (sshusers) and added that group to /etc/sshd_config: AllowGroups sshusers I'm not sure what to try next as i don't get a clear error anywhere. I would like to enable specific accounts to log in so that i can disable root. This is a GridServer/Media Temple (CentOS).

• MySQL blocking new connections, and mysqladmin flush-hosts

  - by aidan

  I'm running MySQL on a remote server, and it suddenly started rejecting all connections: $ mysql -h 192.168.1.10 -u root -p ERROR 1129 (00000): Host 'web' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts' So, I try this flush-hosts command... $ mysqladmin flush-hosts -h 192.168.1.10 -u root -p mysqladmin: connect to server at '192.168.1.10' failed error: 'Host 'web' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'' I.e. it's blocking the very un-blocking tool it recommends. Am I doing it wrong, or will I have to resort to ssh/cpanel/physical access?
