• Apt Stalls When Using HTTP Sources

  - by UltraNurd

  I was getting some to me inexplicable behavior from apt-get/aptitude on an admittedly crusty old webserver. While it was otherwise running fine, as soon as I tried a package upgrade, after a downloading a few updates it would stall completely, then my SSH session hung (and I was unable to reconnect), thus requiring a hard restart. First, I switched to a different package source in /etc/apt/sources.list, but still got the same behavior. At this point I was assuming the NIC was dying in some weird way... but as soon as I changed the package source to use FTP instead of HTTP, everything worked fine, and I was able to upgrade. For now I'm not too concerned since I have an easy work around, but it implies that there's something very weird with my network setup, since it seems to be protocol (or port?) specific. I didn't think any of my NAT setup would affect outbound traffic, but I could be crazy. Any ideas what I should try to look for?

• ServerName no longer works as SQL Server 2008 Default instance name?

  - by TomK

  Folks, Somehow in struggling to install something (Sage MIP), I have unsettled my system's SQL Server 2008 instance names. If I fired up SSMS and connected to "MySystemName" (while logged into MySystemName), I used to immediately connect and could view my databases. Now if I connect to "(local)" or "." I connect just fine...but "MySystemName" gives me a timeout error. If I log in with "." and do "SELECT @@SERVERNAME" it comes back with "MySystemName" just fine. I've double checked that my network name is in the Security\Logins list, and it is, as a dbadmin. Any suggestions? I thought that having SQL Server 2005 Express might be a problem (the "battle of the default instances"), so I uninstalled that. No better.

• My wireless has suddenly became disabled by hardware switch, BIOS, rfkill, fn+f8 do nothing

  - by cwwk

  I have a toshiba l655d-s5145. There is no physical toggle for the wireless, although the f8 key is supposed to do the trick. It doesn't. The wireless has been working since October, and suddenly, nothing. RFKILL reports that the wireless is hard blocked, but unblock wifi, unblock 0, unblock all do nothing. I inserted a usb dongle, and that is also disabled by hardware switch, although rfkill reports that it is neither hard nor soft blocked. My onboard wireless is 02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01) according to lspci. Lsmod reports that these drivers are loaded. rtl8192c_common 75767 1 rtl8192ce rtlwifi 110972 1 rtl8192ce I resorted to reformatting the drive and reinstalling, but that also did not work. In BIOS I restored system defaults as there is no specific entry for wifi. Before reinstalling a pure xubuntu I went into Unity and saw that the airplane mode was on and despite being toggled off, it returned to the on position. I'm not sure where to find airplane mode in Xubuntu. What else can I do? I need my wireless.

• No internet on some devices, still on WiFi

  - by Joost

  Ok, here's the situation. I live with 3 friends, and we often sit in the living room with laptops out. There's a WiFi router in the kitchen, and we have quite a stable connection. The issue, however, is this: sometimes, all of a sudden one of my friends loses internet connection. Even disconnecting/reconnecting to the WiFi network does not help. When we restart the router, though, it works like a charm again. The odd thing is, it happens just for this one Windows 7 laptop. We've switched routers (for a different reason) in the mean time, but the issue remained. This makes me suspect the laptop even more. I realise I've given little details, but I don't really know what to try/do. Any suggestions what it might be?

• Using Arch Linux computer as a server for Rack Apps

  - by wxl

  What would be the best way to go about using an Arch Linux computer as a Rack (as in Ruby Rack, not an actual rack server) server? Here's what I want to be able to do: Automatically deploy on a git push to the server. (I already have this worked out, on post-receive the server checks out the app to /home/git/app from /home/git/app.git.) Run a Rack server application to serve up this app, one that can be restarted on demand. Run a MongoDB server Be able to access the app by going to my-server.local/app or something similar. (It's really only going to be used on the local network, no port forwarding or outside use) Any ideas would be greatly appreciated. I apologize if this seems too "do it for me".

• IoT: Wearables!

  - by Tori Wieldt

  Wearables are a subset of the Internet of Things that has gained a lot of attention. Wearables can monitor your infant's heartrate, open your front door, or warn you when someone's trying to hack your enterprise network. From Devoxx UK to Oracle OpenWorld to Devoxx4kids, everyone seems to be doing something with wearables.  In this video, John McLear introduces the NFC Ring. It can be used to unlock doors, mobile phones, transfer information and link people. The software for developers is open source, so get coding! If you are coming to JavaOne or Oracle OpenWorld, join us for Dress Code 2.0, a wearables meetup. Put on your best wearables gear and come hang out with the Oracle Applications User Experience team and friends at the OTN Lounge. We'll discuss the finer points of use cases, APIs, integrations, UX design, and fashion and style considerations for wearable tech development. There will be gifts for attendees sporting wearable tech, while supplies last. What: Dress Code 2.0: A Wearables Meetup When: Tuesday, 30-September-2014, 4-6 PM Where: OTN Lounge at Oracle OpenWorld IoT - Wearable Resources The IoT Community on Java.net Wearables in the World of Enterprise Applications?

• Cannot connect to IIS 7 from localhost

  - by Wout

  I cannot connect to the local IIS 7 using "http://localhost" in IE. "http://127.0.0.1" doesn't work either. The strange thing is that if I add a binding on e.g. port 81, then I can reach "http://localhost:81". Also turning off the firewall on the local machine doesn't help. The site is reachable from the internet. The local requests don't seem to hit IIS (no entries in the IIS log files). IIS is hosted on Windows Server 2008 R2 from behind a hardware firewall device. Note that I'm a programmer, not a network administrator, so I'm having a hard time trouble shooting this.

• Inbound connections using Internet Connection Sharing in Apple/Mac/Leopard

  - by tlianza

  I have a Mac mini which I'm using to give some other devices wireless access, by sharing it's Airport connection with the local ethernet, and that is plugged into a switch. All devices can get online no problem. (See how: http://www.macosxhints.com/article.php?story=20041112101646643 and http://www.macosxhints.com/article.php?story=20071223001432304 ) The issue is that I need to be able to connect in to these machines as well (at least, for the Slingbox to work). All the devices have 192.168.2.* addresses, and the rest of my local network is on 192.168.1.*. I tried setting a static route so that the 192.168.2.* addresses would use a gateway of 192.168.1.50 (my mac mini's address) but that didn't seem to help. Does anyone know if what I'm trying to do is possible? I admit I'm not certain what Internet Connection sharing is really doing under the hood... perhaps it just does basic nat, and doesn't do the type of routing I'm looking for. If so, anyone know if this is possible?

• Windows 7 - Wireless connection before login possible?

  - by EJ

  Is there a way for Windows 7 to connect to a wireless network before a user has logged in? I have found no good answers to this question elsewhere. Some say it should already be happening if I am using Windows' connection management (WLAN AutoConnect, formerly WirelessZero), but I am using that, and it is not. I can sit at the login screen for as long as you please and it will not connect (watching the router from a separate PC), moments after I login it will connect. Others have said that you need to use the manufacturer's connection management (not Windows'), and they can sometimes have the option for prelogin/prelogon connections, but I am using generic drivers. The device is a Netgear/Cisco WMP300N, with a Broadcom chipset. Netgear/Cisco and Broadcom all claim to not have drivers for Win7, but Win7 apparently comes with a functional driver.

• Has anyone figured out how to use same username with different passwords (Windows)

  - by Coder

  Tried Googling, tried net use, and anything I could, with no results. I have a PC with users, and I have a network server with shared folders. For some users the usernames of the share and local account match, but the passwords are different (a good security practice). Unfortunately, Windows doesn't want to remap the drives on login, and asks for credentials when I try to connect. If I enter the password, the connection succeeds, but it still fails on next login, even if I have checked the "remember" checkbox. On PC: usera@machinea pass1 On NAS: usera@nas pass2 net use z: \\nasip\usera /user:nasip\usera pass2 /persistent:yes Credential store seems to have the user credentials stored... But the mapping fails all the time.

• What would be the best way to correlate logs and events on several hosts?

  - by user220746

  I'm trying to build a log correlation system on multiple hosts. SEC seems interesting but I don't know if it will cover my needs. How could I correlate system events, logs, network events, etc. on multiple hosts at the same time, in real time? Examples: If 5 failed logins happened on host A the last minute and if firewall B has denied lots of access on differents ports on A, then we assume there is a potential attack in progress on A. If the Apache service on host A didn't receive any request for the last N minutes and Apache service on host B did, then the load balancing could be faulty.

• why doesn't my computer resume after sleeping overnight?

  - by bamdad

  i'm having a weird, weird bug that's been haunting me since 11.10. if i listen to music or watch a video and my computer automatically goes to sleep at night, it won't properly resume in the morning. otherwise, suspend and resume works just fine. what happens is that the wi-fi and bluetooth indicator (that turns from white to orange when suspending) stays orange, the display doesn't turn on, and the only option i have is to hard reset the machine. here's what i've tried so far: installing (and uninstalling and reinstalling) laptop-mode-tools switching the proprietary wireless driver (broadcom-wl) to the open source one (brcmsmac & bcma) and back unloading (and blacklisting) all bluetooth modules (rfcomm, btusb, bnep, bluetooth) and stopping (# stop bluetooth) and disabling (# echo 'manual' /etc/init/bluetooth.override) the bluetooth service creating a custom pm sleep action as suggested here: http://ubuntuforums.org/showthread.php?p=11926504 not watching youtube / any stuff that uses flash before going to sleep (i have flashblock, and i checked $ ps aux | grep flash) because i suspected flash to be the culprit trying out different versions of fglrx (the one from the repos, then installing the latest one from amd's site via generated .deb files, then back to the official ones) none of these worked. i remember back in the days of 10.04, there was a gconf key called network sleep: i thought about disabling that, since re-enabling the wireless card seems to be the problem (according to the indicator led), but the option appears to be missing from gnome 3 (unity-2d, whatever). does anyone have any ideas? thanks, bamdad

• How to define a Crystal Report to Windows Default-Printer with a certain papertray

  - by Ice

  I got the job to design some reports with crystal reports XI for a user-group of nearby 20 peoples. Each user has his own printer on his desk. These printers are attached to the network and are served by a print server. The users have thin-clients and are served by citrix with desktops and so has each user his own windows default printer defined. All printers are from the same type and have some papertrays. the reports in question have to go on paper-tray number 3. I have one *.rpt File and so there is one possibility to define a printer and a paper-tray, but how do i define the windows 'default' printer?

• Conflicts with MS Office temporary files when using Offline Folders on Vista

  - by Tambet

  We are using Offline Folders feature of Windows Vista to make files on network shares available when out of office. Mostly it is working, but every time I do a sync I get a lot of such errors: D500E7B8.tmp - A file was deleted on this computer and changed on the server while this computer was offline. There are hundreds of them. I always select all of them and choose resolution "Delete from both locations". But what is causing this and how can I avoid it? I suspect the reason is that we are using Debian and Samba (3.4.7) on our file server. I've been looking for some Samba options that would cure this, but with no success. I learned that probably the cause is, that both Word and Excel are using specific pattern to change files - they never change the original file, but instead always write a new temporary file and rename it to original file, when you click Save. This is documented here: http://support.microsoft.com/kb/211632/?FR=1.

• Oracle Solaris 11 How To Guides

  - by glynn

  Over the past year or so I've been writing a lot of How To Guides for different technologies.

• Cannot resolve a single A Record from client machine

  - by Alex

  I set up a simple Bind server on my VPS and it is working properly. The problem occurs with my local windows machines, which are connected to internet through the home router. I created an A-record named 'dev' and it is invisible from my local network for some reason, though people from other locations can resolve dev.mydomain.com. Ironically, dev.mydomain.com cannot be resolved for myself only. If I add another A-record, say, 'gamma' then it becomes visible from my local windows machines instantly. So this is just for that particular 'dev' name. The only difference is that I had dev.mydomain.com server on another IP but that was a month ago; all nameservers have been changed since then. I tried to reboot my router and flushed dns cache on windows machines: no result. Thank you in advance.

• Nginx save file to local disk

  My case is: In our China company, we have to access one web server in USA headquarter through Internet. But network is too slow, and we download many big image files. All our developers have to wait. So we want to setup a Nginx which acts as reverse proxy, its upstream is our USA web server. Question is can we make Nginx save the image files from USA web server into its local disk? I mean let Nginx act as one cache server.

• IDC Recommends Oracle Solaris 11

  - by user12611852

  IDC published a research report this week on Oracle Solaris 11 and described it as "Delivering unique value."  The report emphasizes the ability of Oracle Solaris to scale up and provide a mission critical platform for a wide variety of computing. Solaris built-in server and network virtualization helps to lower costs and enable consolidation while reducing administration costs and risks. Learn more about Oracle Solaris and the recently announced 11.1 update. In their conclusion, IDC reports: Today, Oracle is a multi-OS vendor that is adjusting to the opportunities presented by a significantly expanded product portfolio. The company has a long history of supporting Unix operating systems with its broad product portfolio, but the main difference is that now Oracle has direct control over the destiny of the Solaris operating system. The company has made a strong commitment to Solaris on both SPARC and x86 systems, as well as to Linux on x86 systems, and expects to continue to enhance Oracle Solaris 11 with update releases once a year as well as Solaris 12, which is already on the road map. Oracle is working to help its customers understand its strong commitment to Oracle Solaris and the product's role as a single operating system that runs on both SPARC and x86 processors. While Oracle Solaris and Oracle Linux are critical assets, the company's crown jewel is the deep collection of software that runs on top of both Oracle Solaris and Oracle Linux, software that creates a robust application environment. The continuing integration and optimization of the software and hardware stack is a differentiator for Oracle and for customers that run an Oracle Solaris stack.

• Any way to stop VMWare workstation from dropping SSH connections?

  - by oljones

  I have VMWare workstation 8 with a few Linux guests. I have had problems maintaining an active SSH connection to my VMs when they are in bridged mode. I first read that the onboard realtek network cards were not well supported so I bought a Intel Pro/1000 GT card. This supposedly had support. But this made no difference. Connections via SSH are active for about the first 3 minutes then hang and die. I have changed the TCP Checksum offload on the Intel and Realtek NICs, but this only works some of the time and even then not for very long. The best I could do was about 20 minutes before the connection was dropped. Any ideas?

• 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 ....

• How do I restore the default applets to Gnome's notification area?

  - by gbacon

  I have a fresh install of Karmic Koala. In a botched attempt at trying to change my default window manager, I somehow removed at least three applets from the notification area: network manager (nm-applet), volume control (gnome-volume-control-applet), and the battery meter (???). Now if I logout and back in, these applets don't run, but I can start them from the command line. Because it's a fresh install, I completely removed my luser account and home directory. After recreating my account, I was frustrated to find that the applets are still missing and no obvious way to add them back. How can I restore the default configuration?

• virtualbox port forwarding - firewall config

  - by Roose

  i have a ubuntu host system with virtualbox running a windows server. In Virtualbox i have configured the network with a NAT interface and port forwarding for the RDP deamon running inside the vm. That works really well - i can connect to the windows rdp service over the internet. TCP *:3389 - *:3389 Now i like to restrict the access to the rdp service to only 3 public ip addresses and have no idea how to do that via iptables / shorewall. Something like: ACCEPT net:91.x.x.x fw tcp 3389 (shorewall rule) isn't working. Would be glad for any hint.
