• iptables drops some packets on port 80 and i don't know the cause.

  - by Janning

  Hi, We are running a firewall with iptables on our Debian Lenny system. I show you only the relevant entries of our firewall. Chain INPUT (policy DROP 0 packets, 0 bytes) target prot opt in out source destination ACCEPT all -- lo * 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 state NEW Chain OUTPUT (policy DROP 0 packets, 0 bytes) target prot opt in out source destination ACCEPT all -- * lo 0.0.0.0/0 0.0.0.0/0 ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED LOGDROP all -- * * 0.0.0.0/0 0.0.0.0/0 Some packets get dropped each day with log messages like this: Feb 5 15:11:02 host1 kernel: [104332.409003] dropped IN= OUT=eth0 SRC= DST= LEN=1420 TOS=0x00 PREC=0x00 TTL=64 ID=18576 DF PROTO=TCP SPT=80 DPT=59327 WINDOW=54 RES=0x00 ACK URGP=0 for privacy reasons I replaced IP Addresses with and This is no reason for any concern, but I just want to understand what's happening. The web server tries to send a packet to the client, but the firewall somehow came to the conclusion that this packet is "UNRELATED" to any prior traffic. I have set a kernel parameter ip_conntrack_ma to a high enough value to be sure to get all connections tracked by iptables state module: sysctl -w net.ipv4.netfilter.ip_conntrack_max=524288 What's funny about that is I get one connection drop every 20 minutes: 06:34:54 droppedIN= 06:52:10 droppedIN= 07:10:48 droppedIN= 07:30:55 droppedIN= 07:51:29 droppedIN= 08:10:47 droppedIN= 08:31:00 droppedIN= 08:50:52 droppedIN= 09:10:50 droppedIN= 09:30:52 droppedIN= 09:50:49 droppedIN= 10:11:00 droppedIN= 10:30:50 droppedIN= 10:50:56 droppedIN= 11:10:53 droppedIN= 11:31:00 droppedIN= 11:50:49 droppedIN= 12:10:49 droppedIN= 12:30:50 droppedIN= 12:50:51 droppedIN= 13:10:49 droppedIN= 13:30:57 droppedIN= 13:51:01 droppedIN= 14:11:12 droppedIN= 14:31:32 droppedIN= 14:50:59 droppedIN= 15:11:02 droppedIN= That's from today, but on other days it looks like this, too (sometimes the rate varies).

• How to allow simple file sharing on Windows Server 2008R2 through VPN

  - by Martin Wiboe

  We are a small, distributed company with a Windows Server 2008R2 installation. I would like to set up a way for our employees to connect securely to this server via VPN and then be able to map a network drive. I have gotten this to work somewhat by installing the Network Policy and Access Services Role on the server and using the default settings. I have also created a network share on the server. The problem is that our connectivity is sporadic (sometimes the service stops listening on the port or simply refuses to authorize correct credentials) and slow. I can always connect through VPN, but mapping is problematic. I would be grateful for the answer on how to accomplish this as well as some guidance on whether I am on the right track. Thanks in advance!

• Toshiba laptop only shows black screen with mouse pointer after starting up

  - by BubblySue

  I only see black screen after the startup. It just shows the logo and the status bar upon start, then it goes black screen with moveable cursor. I tried alt+ctrl+del, but it doesn't work. I pressed shift 5 times and it makes a sound. I already removed battery and restarted it, but still the same. I can go to safe mode and scanned thru there. Still, desktop won't show up. Don't know what else to check?

• How do I connect remotely to SQL Server from Windows client?

  - by humble_coder

  Hi All, Having a bit of an issue connecting to SQL SERVER remotely from Windows. I've verified that all of my settings are correct via SQL SERVER MANAGEMENT STUDIO EXPRESS and SQL SERVER CONFIGURATION MANAGER. I can connect remotely using ODBC drivers from other OSes (e.g. OS X, Linux, etc). However, when I connect with the same credentials from a remote Windows machine using "SQL SERVER" as the driver I am told that the system cannot connect. I've tried creating an ODBC Data Source and I get the same error: Connection failed: SQLState: '01000' SQL Server Error: 14 [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]ConnectionOpen(InvalidInstance()). Connection failed: SQLState: '08001' SQL Server Error: 14 [Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Invalid Connection From the non-windows machines I can use the IP address of the SQL Server just fine. However, on the remote Windows machine, neither IP address nor named instance works. FYI, I can create an ODBC Data Source using the named instance on the machine actually running the SQL Server (but this is, of course, nothing special -- just proof that it isn't completely hosed). One interesting note: If I use SQL STUDIO 2005 from a Windows client machine, I can use the IP address to connect remotely. Still, the whole reason I bring this up is because I need to use a software package I've written to connect to SQL Server remotely from Windows machines as well. Previously the solution was only needed to xfer data from SQL Server into a PostGRES or MySQL database on non-Windows machines (due to DBA preference). However, now they also want to move the data from the legacy software to MySQL even on Windows. Any assistance would be most appreciated. Feel free to provide a full example connection string. Best

• Startech SVx41HDI Series Server Remote Control Usage Question - How do I switch away from a dead por

  - by tajh

  We have a Startech KVM over IP model SV841HDI and it was stuck pointing a port where the machine has been removed. We ended up having to physically plug something into that port in order to switch ports again, meaning that if someone in support accidentally switches to an empty port, we need to have a documented solution for making it useable again. The unit is old, no longer under warranty, firmware updates for it are no longer available (interestingly it runs a powerPC version of busybox). Since it does work well except for this one catch, we would like to avoid replacing it. Reading the manual, you have a several recommended methods. I tried them. Hit the left CTRL key a few times (as well as all the other popular KVM keys I could think of). The VNC GUI offers lots of buttons - none of them switch away from a dead port. The question is: how do I switch away from a dead port on this particular KVM remotely?

• Authentication error in LTSP client

  - by sat

  I am building a LTSP server with LDAP authentication for LTSP Clients. I have configured LDAP server also. When I try to login from LTSP client in GUI, I am getting No response from server, restarting. Then, It's restarting the GUI and comes to the login screen again. I thought that there could be a problem with LDAP authentication. But, When I try to login from Alt+Ctrl+F1 terminal in LTSP client, it is logged in successfully with LDAP user. LDAP Server and authentication is working fine. Even, after executing the below commands, still I am getting the same error. ltsp-update-sshkeys ltsp-update-kernels ltsp-update-image --arch i386 Whether I need to configure anything for GUI login from LTSP Client? How to fix this issue?

• When I type certain characters, they come out as backquotes

  - by JXG

  Very strange behavior. Some background: I bought a new lenovo G550 laptop, running Windows 7. I live in Israel. When I type certain keys, in any application, they are prefaced with the backquote (`). These characters are: Insert, Delete, Left Ctrl (the right-hand one is fine), - (the regular dash: the one on the keypad is fine), =, 5 (the regular one), 4 (the one on the numeric keypad, whether or not Num Lock is on), and PgDn (the regular one). When I press the Fn key with these I don't get the behavior. Does anyone know why this is happening, or how I can fix it?

• Where in the registry are application registered hotkeys stored?

  - by Stuart Allen

  I need to find in the registry the key that is holding the hotkey CTRL-ALT-SHIFT-E. This is normally a keyboard shortcut in Photoshop, but I installed some program that did a global override of this sequence. I have uninstalled that program, but it did not clean up after itself. So, where can I find this in the registry, I just want to delete this key so the global override won't affect Photoshop anymore. I've google'd the crap out of this, there are various program that claim to assist, but none of them work.

• Why doesn't Ghost 2003 offer to fill the destination drive?

  - by Neil

  Because it is dangerously low on disk space, I want to upgrade an SBS 2003 server by replacing its existing 72GB drive with a 364GB drive. When I tried to use Norton Ghost 2003 to clone the disk it didn't suggest that I use the entire new drive. I'm worried that I caused the process to fail by overriding its decision - although the cloned drive boots in Safe Mode, if I try booting it normally then none of the SQL Express instances start and something causes the server to reboot before even the Ctrl+Alt+Del screen appears. Does Ghost 2003 know something that I don't? Or should I be using some other software?

• Unix Shell/SSH config to allow TCP port forwarding without showing a command prompt

  - by Raphael K

  I'm running a Debian Linux. I'd like to have a user account that is able to connect via SSH for TCP-forwarding only, without a command prompt. e.g the following would work (from a remote computer): ssh -D1234 user@myhost but no command prompt would appear. Using a shell like /bin/false or /sbin/nologin is too restrictive as it doesn't even allow the user to log in. A shell that only allows the "exit" or Ctrl+D commands would do the job. I know that something similar is possible to allow only SFTP, but I can't find the equivalent for TCP forwarding. Thanks

• what does STOP service do in Windows?

  - by Radek

  I start my web server as web service on Windows XP. How it was done is described here My web server is coded in ruby/sinatra and I start it in .bat file. That file is used by the service too. Manually I stop the web server by pressing CTRL+C in the dos window. How can I stop the server now as it started via service? I found out that I can stop it via taskkill /f /t /im ruby.exe Is there any way I can use the MMC stop service function to stop the web server? runweb.bat c: cd C:\web ruby C:\web\web2.rb

• TCP/UDP hole punching from and to the same NAT network

  - by Luc

  I was wondering if tcp/udp hole punching would still work when you are in the same network (behind a NAT), and what the packet's path would be. What happens when using hole punching on the same network, is that it will send a packet out with the same destination and source address. Only the source and destination port would differ. I imagine a router with NAT loopback enabled will handle this as it should, but how about other routers? Would they drop the packet, or would a router (the first?) from the ISP bounce the packet back after which it gets handled okay? I'm wondering because I was thinking about using this technique to circumvent a block between peers in a network (like a school network where clients can only access the internet, but any contact with each other is blocked). The only other option is to use a man in the middle as proxy (tunnel?). The disadvantage of this is that you have to have a server with significantly more bandwidth than one that would only do hole punching. Also the latency would increase significantly.

• How can I select a default interactive console in pyDev?

  - by dorian

  Using PyDev 2.7.1 in Eclipse 3.7.2, when I hit Ctrl-Alt-Enter to open a new interactive console, I get a dialog asking me what type of console I'd like to start ("Console for currently active editor", consoles for Python, Jython, Iron Python etc.). Now this selection dialog has no default entry and keyboard selection doesn't work, meaning that I have to use my mouse every time I need a new console, which is kind of tedious. I've checked Preferences - PyPev - Interactive Console, but found no interesting options there. Is there any possibility to define a default interactive console type so that I just have to hit Return when the dialog pops up or, even better, skip this question altogether?

• Can't unlock locked screen, in Ubuntu 12

  - by Camille Goudeseune

  After locking the screen (with a keystroke bound to xlock -nice 8 -mode blank), I can unlock the screen as expected, but only within a few minutes. After being locked overnight, when I hit a key (even Ctrl+Alt combos), the screen stays black with just a brief white flash across the middle of both monitors. The workaround is to ssh in from another host and restart X. Some months ago, this happened every few weeks. By now it happens almost every morning. How do I even start to diagnose this? What might I look for in log files? (The intermittency is particularly troubling.) Failing that, is there an alternative to xlock aka xlockmore? Hardware: 3-year-old HP minitower, GEForce 9800 GT, two Asus LCD monitors. Software: Ubuntu 12.04.2 LTS. Window manager awesome-wm. NVidia driver 304.88. XLock version xlockmore-5.31.

• selecting files in windows-7 explorer just by hovering

  - by bortao

  One of the biggest annoyances for me of Windows 7 vs Windows XP is that you cant select files properly by hovering over them on Windows Explorer (or multi select by holding ctrl). When i hover an item it gets light blue, not selected. Only after a time or after more hovering, it gets selected. I set the delay (MouseHoverTime) to 1. Windows seems to avoid wrong selection by requiring an additional time or space of mouse hovering before actually selecting the item. I tried playing with the values MouseHoverHeight, MouseHoverWidth, MouseSensitivity, MouseThreshold1 and MouseThreshold2 in HKEY_CURRENT_USER\Control Panel\Mouse, but they seem to have no effect over this. (they are currently on (20, 20, 16, 6, 10, respectively). What i want: to immediately select an item whenever the mouse gets over its bounds.

• Make a drive from one machine appear as a physical disk in another machine.

  - by Roberto Sebestyen

  I want to take a physical disk (or part of a disk) in one machine (call it machine-A) and I want to make it available in another machine (machine-B). But I don't want to map a network drive. I want it to appear in machine-B as a physical drive. Even though it is not a physical drive. The reason I want to do this is i want the ability to create shares in machine-B on that drive. Since I cannot do that on mapped drives, I need to use some utility that fools machine-B to think that it is a physical drive, and treat it as such. Both of these machines are windows server 2003. I heard about NFS, It sounds like what could be the solution to my problem. But isn't that a Linux/Unix protocol? What tools can I use to make this happen? Are there any open source solutions? I don't care what the solution is, as long as it achieves the end result, preferably open source solution though. Thanks for reading guys and gals!

• How to fix Ubuntu 10.10 black screen from terminal?

  - by none

  I'm trying to install Ubuntu Desktop 10.10 on an Intel Atom mainboard (Intel D945GCLF2) with CRT that has been running Ubuntu 9.x previously. Both, Desktop live CD / installer and alternate install CD cause the screen to go black (and the status LED blinks). I was able to get a bit further into the boot process with nomodeset as parameter with the Live CD, unfortunately I can't pass GRUB any parameters now that I have used the alternate Install CD by pressing 'e', it just boots. So now I have Ubuntu installed, I get a terminal with CTRL-ALT-F1 but I don't know what I need to do now or how to adjust resolution or video settings from command line.

• Best practice for administering a (hadoop) cluster

  - by Alex

  Dear all, I've recently been playing with Hadoop. I have a six node cluster up and running - with HDFS, and having run a number of MapRed jobs. So far, so good. However I'm now looking to do this more systematically and with a larger number of nodes. Our base system is Ubuntu and the current setup has been administered using apt (to install the correct java runtime) and ssh/scp (to propagate out the various conf files). This is clearly not scalable over time. Does anyone have any experience of good systems for administering (possibly slightly heterogenous: different disk sizes, different numbers of cpus on each node) hadoop clusters automagically? I would consider diskless boot - but imagine that with a large cluster, getting the cluster up and running might be bottle-necked on the machine serving the OS. Or some form of distributed debian apt to keep the machines native environment synchronised? And how do people successfully manage the conf files over a number of (potentially heterogenous) machines? Thanks very much in advance, Alex

• How to open a program on particular desktop?

  - by Vi.

  When I start GUI program, it's window appears appears on currently active desktop (essentially, on random desktop). How to make it to appear on the specified desktop? For example, at startup I want certain programs to be started and distributed to desktops. I've already set up config file of openbox to force some programs to always start on specific desktop. Ideally it should be like: start_on_desktop 1 gnome-terminal --tab -e program1 --tab -e program2 start_on_desktop 2 gnome-terminal --tab -e program3 --tab -e program4 start_on_desktop 3 firefox It should be able to start the same program on other desktop. Also dislike when I start program while being on desktop X then switch to desktop Y and SUDDENLY a program which should be on X appears on Y. When I start lots of programs on and switch often between desktops they end up being in chaos and I need to collect them together and redistribute sanely. Also I want the first initial gnome-terminal to be on desktop 3, but I also want subsequent gnome-terminals to be on the desktop where I pressed the keystroke (also configured in openbox) that launches gnome-terminal.

• Why Are SPF Records Failing?

  - by robobobobo

  Ok I've been going through various different sites, resources and topics here trying to figure out what is wrong with my SPF records but no matter what I do they don't seem to pass. Here's what I have "v=spf1 +a +mx +ip4:217.78.0.92 +ip4:217.78.0.95 -all" I've tried multiple different tools to check my spf records, some give me a pass, some don't. But I can't send mail to certain google app accounts, they just bounce back all the time which is very annoying. Anyone got any ideas? I have noticed that the source IP address is not the IPV4 addresses I've defined, but Cpanel wouldn't let me add that address into it..

• Is Tomcat Shared Session / Cluster between two machine possible?

  - by Snorri

  I have a setup of several Tomcat servers distributed between a few servers, all running the same thing. Apache is on top of Apache and a loadbalancer in front of the Apache servers. I want to cluster the Tomcats using Shared Session to minimize downtime and user interruption while deploying apps. I know clustering works within the same server but is it possible to setup Tomcat in a way that it shares sessions between servers on different machines? = Server 1 == Apache 1 === Tomcat 1 = Server 2 == Apache 2 === Tomcat 2 When Server/Tomcat 1 would be taken down, users and their sessions would transfer over to Server/Tomcat 2 and vice versa.

• My HP ProBook 4520s running Windows 7 hangs intermittently

  - by Rory Alsop

  I have not been able to trace a consistent cause, but a few times a day my laptop will hang for up to about a minute. I can still move the cursor which displays as the wait icon for whatever application I was last in, but cannot carry out any other actions. Unfortunately I can't Ctrl+Alt+Del to bring up a task manager and I just have to wait. I can't pin it down to a particular application either, but generally I have either office apps, a browser or other tools open. I'm tempted to think it may be network timeout on something, as I can't think of anything else which would delay for that long with such a significant impact, but as I'm more a Unix person I thought it would be worth asking here.
