• Cannot connect to FTP server from external host

  - by h3.

  I have a FTP server (vsftpd) setuped on a Linux box (Ubuntu server). When I try to connect with a computer on the same network everything works fine as expected. But as soon the IP is external it won't connect.. I first assumed the port was blocked, but then: localserver:$ sudo tail -f /var/log/vsftpd.log Wed Jan 13 14:21:17 2010 [pid 2407] CONNECT: Client "xxx.xxx.107.4" remotemachine:$ netcat svn-motion.no-ip.biz 21 220 FTP Server And it hangs there. Do any ports other than 21 need to be open?

• Windows 7 - Static DHCP server address with dynamic IP Address

  - by mkstreet

  Is this possible? On my LAN, I would like to setup the network properties such that the DHCP server's address is static. However, I want that server to hand out the IP Addresses and DNS addresses dynamically. The reason is that some devices on the LAN will try to behave like a DHCP server. For example, we use software to push images to computers on the LAN (our computer software configurations are centrally managed). When that imaging distribution software happens to be running, the machines being imaged will get confused as to which device is the DHCP -- the real one or the machine that is sending them the image. So, to remove the confusion, I would like to setup my Windows 7 images such that the DHCP server address is statically assigned. And then that server would assign the IP Addresses and the DNS addresses dynamically.

• how to skip grub dual boot option menu entirely (without picking an OS to boot)

  - by bevcan izBevk

  I'd like to skip the entire Grub 2 interface, where I have to decide booting Linux or Windows im running linux ubuntu lastest version (14.04.1 LTS) and windows 8.1 both 64 bit versions. I've installed easyBCD software, which I want to use as (my only) boot manager. Issue: whenever I run my computer, I get grub interface to pick Linux or Windows, after that I get easyBCD interface where I have to pick linux or windows again. If both choices are the same, proper system boots, else I get thrown back to beggining (grub UI). I'd like to somehow delete / skip grub from appearing. TLDR title :) thank you for helping!

• Poor TCP loopback throughput on Windows

  - by Yodan Tauber

  I measured the throughput of a locally bound TCP socket connection on my computer (Intel Q9550, 64 GB RAM, Windows XP 64 bit) using iperf. I got dissatisfying results (around 1.6 Gbit/s) each time, no matter how I tweaked the TCP settings (buffer length, window size, max segment size, no delay). I got similar results when I tried netperf. Now, I understand (from sources like these) that the average throughput of a loopback connection should be around 5 Gbit/s. What could be the reasons for such poor performance?

• Changing the IP address with a name [closed]

  - by fede

  I have a web server (xampp) in a particular PC running on my LAN, and I added the following line in the 'hosts' file : 127.0.0.1 mysite. Then, in another PC connected to the LAN, I'm trying to acces the previous web server by typing 'http://mysite/index.php' on the web browser, with no luck. But if I type the IP from the server computer (http://192.168.2.87/index.php) I am able to access the web site. So, what should i configure so when i type 'http://mysite/index.php' I get the same result as http:// 192.168.2.87/index.php ?? Thanx!

• Bug: unable to handle kernel NULL pointer dereference at

  - by maria

  I have recently installed new system on my disc, Ubuntu 12.04. Installation proceeded without problems, I started installing additional software and put data from other discs. I had already two times bug report, it was quite long, and I have no idea how to acces to log file (which probably is somewhere saved) and since I had to switch off the computer using the button, anything else was possible, here is just a small part of it (what I've noted on paper) could not write bytes: Broken pipe speach dicpatcher disabled: edit etc/default/speach-dispatcher saned disabled: edit .... and than: BUG: unable to handle kernel NULL pointer dereference at 0000009c I've run Memory test in GRUB, everything is fine. First time it occured when I was using rsync, second time when I was trying to install texlive. Should I install whole system once again? Or can it be hardware problem? Or something else? If there is any hardware details which may be relevant, please ask, since I have no idea what is happening, I don't know what kind of information could be useful. Thanks P.S. dmesg output:

• Delete Grub and OpenSuse but keep Windows 7.

  - by elvispt

  Hi. Here is my problem. I have OpenSuse installed alongside Windows 7. Grub is the boot loader from where I access OpenSuse and Windows 7. I want to delete Grub and also the OpenSuse partitions. My first, failed, approach was to insert the Win7 DVD, choose Repair your computer and then enter the commmand prompt. I then typed "bootrec /fixmbr" and restarted. It didn't worked. Grub was still there, so was Windows7. I then tried using "bootrec /fixboot and /rebuildbcd and neither worked. So what can I do to fix this? I remember when I was using WinXP this was much simpler. I would just type fixmbr and that was it. Any clues? Thank you.

• Documenting software-updates semi-automatically in MacOS X by parsing log files?

  - by Martin

  I'd like to document changes I made to my computer (running MacOS 10.6.8) to be able to identify the sources of eventual problems. Mostly I install updates when a software notifies me about a newer version and offers me a dialog to download and install the update. Currently I'm documenting those updates "by hand" by noting in a text file, when I have e. g. installed a Flash-Player update or updated another 3rd party software ... I wonder if I could achieve that easier and semi-automatically by parsing system logfiles for certain texts like "install" and that way directly get the relevant information: what has been installed (Software and version) when has been installed where has it been installed/what has changed Is there a way to extract such information by a script from the existing logfiles?

• Vertically resize two windows at same time?

  - by Guy

  I love the new feature in Windows 7 where I can grab the title bar and "slam" a window against the right edge of the computer and it will size that window to the right half of the screen. I can then grab another window and do the same against the left side of the screen. Once I've done that I often find that one of those windows needs a bit more horizontal space and the other can do with less. So I grab the edge in the middle of each window and resize that window so I can most efficiently use my screen space. Problem is that I have to do this twice, once for each window. Is there a way to grab the inside vertical edge of both windows at the same time so that I can make one wider and the other smaller at the same time?

• Suggestions for hosted file sharing services

  - by Jon

  Before I pose my question, I will give some insight as per my scenario: I work for a small business (cost is an important factor) Our bandwidth is limited and would not support an in-house FTP server We need to share files (mostly pdf, inDesign, Illustrator documents) to our clients, and as we expand, we are finding that our current locally-hosted FTP solution is too slow and is becoming a detriment to our sales team. What we need is a remotely hosted solution to share files with our clients, specifically with the following features: Greater than 100gb of secure storage The Ability to distribute unique log in credentials to clients, granting access to a personalized directory or folder, while limiting access to other files on the server. A relatively simple web-based UI for clients with limited computer knowledge We have considered a dedicated remote server, and web-based services (box.net, yousendit.com, onehub.com, filesanywhere.com) but I am unsure as per the direction we should be taking - have I left another solution out? What would you suggest? Thanks in advance.

• TrueCrypt - "Warning! Password locked: Fixed disk0" error message on boot

  - by Tibi

  TrueCrypt - "Warning! Password locked: Fixed disk0" error message on boot. When i start my laptop (Acer TravelMate 2410). after the starting memory check, the screen goes full black, and a message appears for about 3 seconds: Warning! Password locked: Fixed disk0 and after that, disappears, and next message comes out: Operating System Not Found and all stops here. Windows Xp was installed on it, before this came. TrueCrypt cd (witch was made during the process of full encryption) is not working, not in restoring MBR, no even in decrypting my drive - completely useless. Note: I detected some short of boot sector errors (i dont know the amount) on my drive before this happened. Please, i would greatfully thank every comment, or suggestion, because my computer is unusable now. The HDD is a Samsung HDD, 160Gb. Other preferences: Acer TravelMate 2410 Notebook, 2 Gb RAM, 1500 Mhz Intel Celeron M processor. Regards

• Why won't Windows use the other CPU cores?

  - by revloc02

  In Windows Task Manager the Performance tab shows the first CPU maxed out, the other 7 just idling along with the occasional spike. What gives? More info: I've got 8GB and only 4.5GB are being used. The Processes tab has no indication of any process hogging processing power. In fact System Idle Process is 98-99. When I program stuff and have like 8 to 12 applications going (several directly unrelated to programming of course) my computer slows to a crawl.

• Do I have a bad SD card?

  - by User1

  I'm trying to copy data from my computer to an SD card. After a few hundred megs, I keep getting the following errors in dmesg: [34542.836192] end_request: I/O error, dev mmcblk0, sector 855936 [34542.836284] FAT: unable to read inode block for updating (i_pos 13694981) [34542.836306] MMC: killing requests for dead queue [34542.836310] end_request: I/O error, dev mmcblk0, sector 9280 [34542.837035] FAT: unable to read inode block for updating (i_pos 148486) [34542.837062] MMC: killing requests for dead queue [34542.837066] end_request: I/O error, dev mmcblk0, sector 1 [34542.837074] FAT: bread failed in fat_clusters_flush [34542.837085] MMC: killing requests for dead queue These were all files I copied from a smaller SD card. I just want to transfer them to my new, larger card for my phone. I tried the same experiment with different files on a different machine and the card failed again. Reading data from the old card went fine. My systems are older and the new SD card is new (16GB Class 4). Could this be that my computers are too old? Is there a definitive test to verify if my SD card is bad?

• How to use HFS formatted pen drive in Windows 7?

  - by row-sun

  I recently used disk utility in my mac book pro to format my 8 GB pen drive to install OS X. After that I formatted my pen drive from disk utility as FAT32 so that I would be able to use it in windows. But in windows the pen drive does not show up. When I right click on my computer and click manage and then disk management, the pen drive is listed there, but it doesn't show up in the explorer and I cant use it. I tried to do many things but I'm still not being able to use it in windows though I can use it in Mac OS X. Could anyone help? Thanks.

• Not recognized as operating system on startup

  - by mastabruce

  I am new to Ubuntu and just decided to install it in (on my new lenovo thinkpad) in addition to my windows 7 operating system. Now, whenever I reboot the computer, it only runs window 7. I went (in windows) to Control Pannel ? System ? Advanced Settings ? Startup and Ubuntu is not even listed as a choice for operating system. I tried installing ubuntu again, but now it wants to partition the already partitioned windows folder. I can't figure out how to get Ubuntu, which seems to be installed, to run. I saw on another question here that I could be able to edit my mrb settings using EasyBCD but I can not figure out how to choose ubuntu as an operating system. My disk is already partitioned (seen from the attempted second install) so I'm pretty sure it is on the disk. Basically, how can I get ubuntu to run when I can't choose it as an operating system? Thank you for your help.

• Redirecting HTTP traffic from a local server on the web

  - by MrJackV

  Here is the situation: I have a webserver (let's call it C1) that is running an apache/php server and it is port forwarded so that I can access it anywhere. However there is another computer within the webserver LAN that has a apache server too (let's call it C2). I cannot change the port forwarding nor I can change the apache server (a.k.a. install custom modules). My question is: is there a way to access C2 within a directory of C1? (e.g. going to www.website.org/random_dir will allow me to browse the root of C2 apache server.) I am trying to change as little as possible of the config/other (e.g. activating modules etc.) Is there a possible solution? Thanks in advance.

• IE8 Stopped Keeping History

  - by BillP3rd

  Like the title says, apparently my IE8 has stopped keeping the history of pages I've visited. I've searched SU and Google and can't find anything that seems to describe what I'm seeing. I have IE set to retain history for 999 days (the maximum allowed): As you can see below, apart from today and last Thursday, IE appears to be oblivious to any activity more recent than three weeks ago. Clicking on either "Thursday" or "Today" reveals no recorded history, however. Very odd behavior. Finally, the history does extend back 30 weeks to when I built the computer, and there is recorded history for every week. I'd appreciate suggestions. NB. Windows 7 Ultimate, x64 (but 32-bit IE8).

• Is full partition encryption the only sure way to make Ubuntu safe from external access?

  - by fred.bear

  (By "external access", I mean eg. via a Live CD, or another OS on the same dual-boot machine) A friend wants to try Ubuntu. He's fed up with Vista grinding to a crawl (the kids? :), so he likes the "potential" security offered by Ubuntu, but because the computer will be multi-booting Ubuntu (primary) and 2 Vistas (one for him, if he ever needs it again, and the other one for the kids to screw up (again). However, he is concerned about any non-Ubuntu access to the Ubuntu partitions (and also to his Vista partition)... I believe TrueCrypt will do the job for his Vista, but I'd like to know what the best encryption system for Ubuntu is... If TrueCrypt works for Ubuntu, it may be the best option for him, as it would be the same look and feel for both. Ubuntu will be installed with 3 partitions; 1) root 2) home 3) swap.. Will Ubuntu's boot loader clash with TrueCrypt's encrypted partition? PS.. Is encryption a suitable solution?

• Setup IPv4 local on IPv6 VPS

  - by A.D.

  I have a dedicated server running multiple IPv6 only OpenVZ containers. I want them to be able to communicate with the IPv4 internet, but I realized that isn't going to be possible with IPv6 only. So they need to have an IPv4 address as well, not sure if a local address will work for it, but pretty sure it should. I added 169.254.1.100 in the container .conf file, but when I try to start it, I get this : Adding IP address(es): (the IPv6 address) 169.254.1.100 arpsend: 169.254.1.100 is detected on another computer : 00:04:9b:f2:b0:00 vps-net_add WARNING: arpsend -c 1 -w 1 -D -e 169.254.1.100 eth0 FAILED I did a lot of research, and searched serverfault before posting this, but found nothing relating to this.

• Backup folder on sometimes attached external usb harddrive

  - by ctrler

  My girlfriend no longer has space her laptops drive to store her photos. The drive she has now is 750GB, so to go to a bigger drive would be expensive, as there isn't many 1.5tb 2.5 inch 9.5mm hdd on the market (as of now, there is only one). Because of that, I am thinking of moving her pictures to a cheap external usb hdd. As of now, I'm automatically backing up her important folders (My Documents, Pictures, etc.) using Windows 7 default backup software to a network drive. My problem is that I don't know of a good solution to automatically backup a folder residing on an usb disk. The usb disk won't be attached to the computer all the time, so I can't just treat it as a normal backup folder. Sometimes the backup would run and the folder would not be there! Anyone knows any software or methodology to backup folders on external usb hard drives that are not always present? Thanks

• How do I reinforce compression options?

  - by Gooberpatrol66

  Shortly after I got my computer, I enabled NTFS compression on it, selecting the option to compress "all files and subfolders". I recently noticed that several folders on my PC are not compressed anymore, including "Program Files" and "Windows". I suspect this happened when I installed Windows 8.1. The problem is, the only way I can think of to fix this would be to uncheck the tick box under "Properties" for my drive, thus decompressing everything on my drive, and then re-check it with the "all files and subfolders" option. Is there a way to compress all the uncompressed folders without first decompressing the compressed folders?

• after BIOS splash, will not boot -- asks me to select an OS, but it just reboots

  - by user92040

  I'm running Linux Mint 13 MATE 64-bit. Everything has been working for several weeks. Yesterday, when I tried to boot up my computer, after the BIOS screen flashes I reach a screen with a black background that reads at the top: GNU GRUB version1.99-21ubuntu3.4 Then there is a box in which I can select from the following lines: Linux Mint 13 MATE 64-bit, 3.2.0-31-generic (/dev/sdb2) Linux Mint 13 MATE 64-bit, 3.2.0-31-generic (/dev/sdb2) -- recovery mode Previous Linux versions Memory test (memtest86+) Memory test (memtest86+, serial console 115200) At the bottom it reads: Use the ? and ? keys to select which entry is highlighed. Press enter to boot the selected OS, 'e' to edit the commands before booting or 'c' for a command-line. I have no idea why it started doing this and, worse, I have no idea how to get out of here. No matter which option I select, I can't get it to boot the OS. If I select either of the first two, it reboots to splash the BIOS and then I'm right back where I started. If I choose "Previous Linux versions" I get essentially the same screen with only two choices (which are the same as the first two choices listed above, Linux 13 MATE and the recovery mode). Again, choosing either one of those results in a reboot. If I try to run either of the memtest options, it reads: error: unknown command 'linux16', Press any key to continue... Then it brings me back to the same screen Can anyone help me please? Intel Core i5-2500 ASUS P8Z68-V LX Intel Motherboard G.

• Monitoring remote employees with screenshots and screen sharing?

  - by Lulu

  I'm looking for a way to track and monitor my online employees I hire on Elance, oDesk and such. The tool should be able to: Produce screenshots on set intervals. Provide real-time screen sharing. Preferably track computer usage while user is logged in as "working" + state which task was done in that time. If I have no all-in-one solution, I will go with RealVNC for screen sharing. But I still need a recommendation for the other things. Thanks

• How can I view a .eml file from command line in Windows Vista?

  - by Nosrettap

  Ok, so my parent's computer crashed (horribly - corruptedRegistry) and I'm trying to access one of their e-mail files that is saved locally on the hard drive. I can't launch Windows itself so right now I am in a "bootup command prompt". I've navigated to where the e-mail appear to be stored C:Users\[userName]\AppData\Local\Microsoft\Windows Mail\Local Folders\Inbox and it shows a list of what appear to be the files. The problem is, they are .eml files and I can't seem to be able to open them. I've tried 'vim' and 'vi' commands but it tells me that 'vim is not recognized as an internal or external command. Does anyone know how I can view .eml files from command line? Thanks

• Ubuntu 11.04 64bits Keeps Randomly Freezing

  - by user971602

  This has been a real headache for me since the number of freezes has increase from twice a week to about 1 or twice a day. The system just halts and nothing can be done but hitting the restart button. At the beginning I thought it was related to Flash since I was getting random freezes when playing full screen flash videos online. I also thought it could be the wireless pci card. But the system has freezed using browsing around GNOME. The truth is, the freezes are really random and strange. I checked this thread Ubuntu keeps randomly freezing and try to ssh my computer using another one, but I could not ssh since it was really totally frozen. NumLock or CapsLock wasn't responding or blinking. Since I could not ssh I, also ignored this article https://wiki.ubuntu.com/X/Troubleshooting/Freeze According to my wife, the system has also halted under Win7 Pro 64bit but with less frequency. Here is my system configuration Intel Core i7 2600k ASRock Z68 Extreme3 gen3 Motherboard Crucial M4 128GB CT128M4SSD2 SSD WD Caviar Green WD10EADS 1TB SATA II G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR2 OCZ ModXStream 600W Power Supply Rosewill RNX-N300X PCI Wireless Adapter No external Graphics Card I remove the Wireless card and used Ethernet to see if the problem was the that, but I got a freeze after doing that. I also ran memtest86 and everything was ok. The only other thing I might suspect of is the SSD. I will try to clone the SSD to a HDD to see if that solve the problem. At this point I am stuck with the freezes. Do anyone have a clue of why this is happening and how can i solve this?
