• Ubuntu server security; Is this enough?

  - by Camran

  I have a classifieds website, which uses php5 and mysql, and also java (solr). I am new to linux and VPS... I have installed SSH, and I have installed IPtables, and also I have PuTTY which I use as a terminal. Also, Filezilla is installed on my computer, and whenever I connect to my VPS, the "host" field in Filezilla says "Sftp://ip-adress" so I am guessing it is a safe connection. I used this command to find out if I had SSHD installed: whereis sshd and it returned some places where it actually was installed. So I havent actually installed it. Now, my Q is, is this enough? What other security measures should I take? Any good articles about security and how to set it up on a VPS? Remember, I have a windows xp OS on my laptop, but the OS for my VPS is Ubuntu 9.10. Also, I have apache2 installed... Thanks

• messed System Files on Mac PPC

  - by glider

  My buddy deleted her System folder from her PPC Mac wanting to get that space for something else. She copied it first in another drive (she had partitioned disk).She haven't emptied the Trash Bin yet. The screen just froze right after she moved the folder to Trash. We tried to use the install disk but even if we try Power-C on booting,it would try to continue,display the apple logo page then quickly follow it with black screen filled with dumps of hex codes and "We are hanging here..." We have a Windows-based PC that we tried to connect using ethernet cable but we can't find her computer from there. What should we do now???

• How many site visitors can my server handle? [closed]

  - by coolboycsaba

  I have a website, and I want to host it on my own computer, but I'm wondering if it's good enough. The website checks if the user is logged in and then displays 15 items (title, description) from a mysql database and the rating (stored in another database) and the comments (another database) for each item. It also displays some stats (number of items, comments). I also have an image for each item. My specs are: AMD Athlon 64 X2 Dual Core Processor 5600+ 2.90 GHz RAM: 4.00GB Windows 7 64bit So what do you think, how much visitors and items could it handle (at once or daily) ? My internet connection is good, around 7-10 mb upload and same download speed

• What monitor specifications should be taken into consideration to avoid eye problems? [closed]

  - by coding crow

  I spent time programming on my 13.3" laptop for 8 to 10 hours a day. I was planning to buy a good monitor. Now that I have developed CVS buying a monitor has became an immediate priority. I have spend some time trying to understand what I should buy and why. I could only zero down on the size (20") and LED. So, I'm looking for advice on many other factors like resolution, pixel density, panel technology and so forth. What should I look for in a computer monitor to avoid further eye problems? Why?

• FTP client hangs after a while

  - by lfbn

  I'm using Linux Ubuntu 12.04 with curlftpfs to connect to a remote server. After mounting a remote ftp, opening and saving files with vim, list directories and files, for some time, after a while (no more of 30 minutes), with no reason it hangs. After opening other terminal tabs, all tabs remain iddle...but when using filezilla without restart the computer I still can get to the server and working with no problem. When using Nautilus, instead of curlftpfs, I'm having the same problem. After a while it hangs. Can anyone help me please?

• Is there a way I can find if my hard disk data was stolen? [closed]

  - by Bridget

  How can I tell if the repair shop stole my hard drive? I had my computer in the shop for a couple of days to get a diagnostic check and he quoted me $130. I have a family member who said he would do it for $30 so I rejected the offer and requested it back. When he returned it I hooked it back up and now I get a low disk space warning; when I dropped it off I had at least 50 gb of space left, on a total of 149 gb and all my pictures movies, and music are gone. Can I find if he indeed did steal my hard drive or something?

• Reset windows XP machine dates

  - by KL

  What steps would you take to make a windows xp machine appear that it hasn't been logged on to since some past date. Not to a forensic level here, just to a casual inspection. Fyi this is not intended to do anything destructive to someone elses machine. This is for my own use believe it or not. And no, I'm not trying to hide from daddy that I used his computer. If you want to be sarcastic here, please come up with something half way amusing, thanks.

• Upgraded from ubuntu 12.04 to 12.10 issues

  - by ubuntu novice user

  I recently upgraded 12.04 to 12.10 ubuntu and then all hell broke loose. Being more specific, I have a Compaq machine and its hard disk is partitioned into 3 parts, so when I installed Ubuntu 10.04, I installed it in windows, since then have upgraded with each new ubuntu release via the update manager without any problems. I have installed the 64 bit versions. 12.10 downloaded via update manager, and initial downloading of packages was without problems, however, as it tried to install the packages, error messages appeared. The first was one about missing lib files, but I clicked to continue, since I am a relative novice on ubuntu. It continued, and during the restart process, when it was powering down, the computer hanged on the shutting down bit without rebooting for more than half an hour, so I manually shut down the machine and restarted it. Then a new error message appeared stating could not find disk, and I hit the manual fix option, and it now boots to an empty ubuntu desktop with my wallpaper but no launcher and the graphics appears as if this was put on a 640 x 480 resolution, and the screen no longer fits onto my 19" LCD. I had to use Ctrl-Alt-T to log out and then restart from there. How can I resolve this issue. Please help!

• Windows 7 100% Memory Usage (without any process listed as using that much memory)

  - by Paul Tarjan

  When I plug my external USB 2TB hard drive into my windows 7 box, my RAM usage climbs up to all 4 Gigs (but in task manager it shows that all process are small) and the hard drive is churning like crazy. My CPU is only about 20% utilized All I can think of is there is a Virus scanner or an indexer running like crazy. I've tried to kill all virus scanners (AVG and Windows Security Essentials) and it still keeps going. My computer is completely unusable as everything is constantly swapping. I've tried leaving it on for 2 days now and it still hasn't finished whatever it was doing. Any ideas?

• New Kingson SSD drive fails after 1 week

  - by user35356

  I upgraded the hard disk in my notebook to a 128GB Kingston SSD V100. Everything worked fine for about a week then out of the blue the notebook would not boot up any more. A black dos-like screen was shown with the options to try and boot normally or attempt to repair windows. Neither option would do anything. When I removed the drive and tested it in an external usb case no other computers are able to access the drive either. Is there anything I can try to fix it myself? The drive is partitioned into three drives and when it's connected through an external usb case to another computer I can see the partitions, just can't access anything on them. Does this mean the drive might be recoverable?

• How to access network shares, printers, etc.through Windows 7 Built-In VPN?

  - by mbrion

  After I have successfully connected to a Windows 7 box via the built-in VPN: how do I access shares, shared printers, network appliances, etc.? So, call me bad at googling, but: I can find dozens of articles on "How to Set up a VPN Connection" and "How to connect to a VPN" for Windows 7... but I can't find a single article on how to access resources after connecting. I have a home VPN set up in Windows 7; I was able to connect to it from my friend's Windows 7 machine last night. I expected to be able to UNC into my shares; I also expected to be able to go to "Start Computer" and Click "Network" on the left side, and then see all of the devices on my home network (while the VPN was connected). Am I missing something obvious? How do I make this happen?

• Windows Mobile 6.5 Remote desktop

  - by mpop

  I am trying to help a friend out, we have gotten him able to connect via his windows mobile 6.5 phone to his computer via remote desktop. The problem we are running into is that the program that he needs to be able to access does not work at lower resolutions (such as his phone has) and most of the program screen is cut off (it is a VB program) Is there a way to have a "higher" resolution on the screen being sent to the Windows Mobile 6.5 phone and just have him scroll up and down on the screen? Right now replacing the phone is not an option (it might be 6 months down the line, but for now it is not an option).

• Can I use Server Monitor with a non-server Mac?

  - by Chris

  I have a computer I use as a simple file and web server. I am simply desiring to be able to monitor load, traffic, memory usage, etc via Server Monitor. I have also downloaded an app for my iPhone which does the same thing, but it uses the same protocol that Server Monitor does. Is it possible to get Server Monitor to recognize my non-server box as a server so I can monitor this information? For reference, I am running 10.4.11 on this PPC box. Thanks in advance!

• Ubuntu is unresponsive and scrolling is very jerky

  - by peterpipe

  I'm new to Ubuntu. I've been using 12.04LTS for over a week now. For 3 days it was great but now I'm having a number of problems. I'm using an Acer Aspire one D255 it has a 250GB HDD and a 1GB Memory. My browser is Firefox. Pages freeze occasionally and I wait for over 10 minutes and have to use the computer's 'off' button. Pages crash. On facebook some pictures don't load and I have to close down and restart a couple of times. Scrolling can sometimes be very jerky. Downloading software has become a problem and I have a 'no entry' sign in the top taskbar. I've looked at this page for some help but the words used and the explanations are not helpful to someone like me who has little knowledge of this. Please - 'Ubuntu for dummies'. I'd like to continue using Ubuntu but am close to giving up.

• I have a bunch of CHK files on my USB Drive that used to be my stories that I saved on there. How do I get them back?

  - by Susana

  Ok, so I am not sure why, but my USB flash drive isn't showing all of my stories that I typed and saved. It might be because I removed the USB flash drive without ejecting it safely. All of the data was there on my flash drive, I just couldn't see it. The capacity was almost full so I'm pretty sure the data was there. So, when I decided to run and check to see if there were any problems, the computer found that there were. I think it found my files, but now they are CHK files and I don't know how to get them back. Can someone please help? This is my life's work here!

• DVD Drive Has Stopped Recognizing Discs

  - by ricree

  My DVD drive no longer recognizes dvds, but does recognize CD-ROMs. When a DVD is in the drive, the computer continues to act as though there is no disc in the drive. However, when a normal CD-ROM is in the drive, it appears to work normally. I have tested on several discs, both video and game, and the behavior is consistent. I have also tested this on both Windows Vista and Ubuntu 9.10, and the issue remains the same. Can anyone recommend a way to fix this?

• Long term system health monitor

  - by user30336

  As an experienced user, I sometimes notice that things are not going well with my computer. For example, my backup drive recently started cycling up and down, so I guessed it was probably dying, and replaced it. I detected this with my ears. Windows did not seem to notice or care. There ought to be software that monitors overall system health by keeping track of things like this, so that unusual events or increasing error rates will not be shrugged off. Among other things: disk errors that are recovered, corrupt network packets (at above the baseline expected rate) and crashes of trusted programs are early warnings. Is there any software that tries to use this kind of monitoring to warn of impending trouble?

• Can't connect to Wireless

  - by SimplyRed37

  Good day all! I hope you are doing good. I have performed a WUBI installation of 12.04 on my HP G62 laptop, which has an Atheros AR9285 wireless chipset. Everything works fine with my wired network connection. However, wireless is unable to connect to my wifi network. I enter the WPA2 key and then it attemps to connect, but eventually comes back, asking for the WPA2 key again, as if it was not good. All of the other laptops in the household are able to connect, using the same key (I configured them all, so I am 500% sure of the WPA2 key). Any idea as to what could be causing this? I can definitely post the output of CLI commands like "rfkill list" or "sudo lshw -class network", or "ifconfig". I have installed Ubuntu a few time but I am definitely still a newbie, but I am definitely computer savyy. Looking forward to suggestions . Thanks in advance !!! Dan...

• hdmi output of windows 7 does not stay alive

  - by sjors miltenburg

  I have built a server that is connected to ONLY my tv (with hdmi). If I switch my tv to hdmi and boot my server I get the expected result (windows is displayed on my tv) and I can fully interact with it, no problem. However when "some time" passes the image on my tv dissapears and it seems the server is not outputting any hdmi signal anymore. It does not wake up on mousemove or keyboard presses. I can still interact with my server through a remote desktop session. The only way to get the hdmi output back is to reboot the server. I tried to prevent the computer from "sleeping" but this did not work. I tried upgrading from windows vista to windows 7 but this also did not work. Do you guys have any other ideas?

• Computers with Small Capacity SSD - For caching?

  - by RXC

  Recently, in newsletters from websites, I have been seeing computers for sale from manufacturers that include an HDD and an SSD but the SSD has a small capacity like 24 GBs. I don't know if this still holds true, but I learned that when building a computer, you would want to install your OS on your fastest hard drive. I do a lot of PC gaming, so I install my OS and games on my SSD, because I learned that games and many applications make lots of system calls to the OS and performance can only be as fast as the slowest piece. Why these computers come with small capacity SSDs? Most OS's take up around 20 to 30 GBs of space, so what are the benefits of such a small SSD? Are these small size SSDs for caching? and what exactly does caching mean (what does it do and how does it help)?

• Run SSH trough a proxy

  - by Row Minds

  I have a question. How can i run SSH trough a proxy or a SSH Tunneling Protocol? For example i have a computer(Ubuntu) with ip eg. 123.123.123.123 and i want to connect to my server trough a proxy eg. 111.111.111.111 so i can see in lastlog that the last authentication was made from 123.123.123.123 . I need this because i cannot access a certain server at work only with an specified range IP. What i tried so far was http://daniel.haxx.se/docs/sshproxy.html where i used ssh -D 1 [email protected] -p 443 where i had 127.0.0.1 forwarded to a SSH Tunneling Protocol http://www.nixtutor.com/linux/installing-and-configuring-an-ssh-server/ (i configurated listening on port 443 but no result, still no connection (denied) ...) This question may sound simple, but i can't figure it out, can you please help me? Thanks.

• How to remove GRUB from dual boot (Debian and Windows XP)

  - by All

  I have a computer witch cannot be boot from CD or USB. I have Debian and Windows XP with dual boot via GRUB. Now I want to uninstall Debian and GRUB and restore the Windows MBR. I can enter boot Debian and Windows OSes, but no boot from CD or USB for recovery. How can I remove GRUb and restore MBR from within Windows XP or Debian? NOTE: I asked this question before, but after accepting the answer, I found that Windows XP does not have fdisk command. However, I think it is too late to continue the discussion there; thus, I asked this brand new question.

• Why are Google search results not working for me? Does it have to do with otnggrneohai? [closed]

  - by shaahin

  Possible Duplicate: What to do if my computer is infected by a virus or a malware? I can't use Google search results right now. The actual searches return results that look valid, but whenever I click on a link, I'm redirected to strange sites. I believe I'm being affected by a virus that has something to do with the string "otnggrneohai." I was running Windows 7 Home with Microsoft Security Essentials, but Microsoft Security Essentials has been deleted. I did not delete it myself. Here is the screen shot, I did a search test in google videos:

• Virtual IP, and Reverse Proxying Ports (Making up terms)

  - by macintosh264

  So here is the exact situation that I have I have 2 game servers in my house. One on port 25565, and the second on 25567. I have only one IP in my house I need to get a "virtual IP" for the second server. Some way of giving the computer that runs these game servers a second IP (linux) I need the Virtual IP to receive connections on 25565 and forward the data to 25567. Although if linux recognizes the second IP in networking I assume I can bind to the second IP on port 25565

• Find an old static IP address on a mac backup?

  - by Joe

  I have an old backup of a mac via time machine, and I was wondering if there is some sort of accessible file that would have the static IP of the old computer it was backed up from. If you are curious, I am in IT and it is a PITA to get a new static IP here. I am just trying to use the old one to save some hassle. I've tried searching through the system log with no success (but I might be doing it wrong- grep with a regexp for an IP). Thanks!
