• How to document linux server configuration?

  - by Margaret Thorpe

  Hi, I have about 20 linux servers which I need to document the configuration of. I do not mean the detailed configuration of services, but rather user accounts, databases, databases accounts, ip addresses, physical location, SSH port etc. etc. I know all this data is stored in config files, but I want to centralize it all. I am considering just creating a spreadsheet to record this data, but was wondering if there is something better (perhaps a small php/mysql app) which would be more structured and complete than a hacked together spreadsheet. What do you use?

• EC2-like virtualisation platform with non-RDP access

  - by code'

  I'm looking into setting up a few small VMs. The trouble is the software I intend to install on them (Cisco VPN Client) blocks out networking (other than to the target VPN destination...) with no workaround. This means that Remote Desktop or other methods of connecting to VMs that go via the Internet (e.g. GoToMyPC, LogMeIn) are a non-starter. What I'm really looking for is an EC2-like platform but which gives direct access to the VM through (for example) Hyper-V Manager. Sadly the only way they all seem to offer to remote control the VMs is direct access via Remote Desktop, whereas I need to be one layer above that (if that makes sense). A viable alternative would be to run virtualisation software within a Windows EC2 instance; obviously hardware virtualisation is impossible but I wonder if there are any software virtualisation platforms that could be run and that would work. Does anyone know if something like this exists/is possible? Thanks! C

• How to associate a domain name and IP address?

  - by StackedCrooked

  The situation is as follows: I am renting a dedicated server using SliceHost. On this server I have installed a small HTTPServer. I can verify that it works by nativating directly to its IP address (example). I have also purchased a domain name from gandi.net and would like to link it with to my server. However, I'm having much trouble finding clear instructions on how to create this link. After a few hours of reading documentation and trying out things I ended up the following configuration. on the DNS registrar I have specified the following settings: on the Slicehost server I specified these "records": But it doesn't seem to work. I end up on this page telling me the domain name is not available. Does anyone have an idea what I am doing wrong?

• Webserver security, intrusion detection, and file intregrity

  - by enfield

  I would like to add some type of tracking / alerting on some linux webservers running PHP and Apache. In doing searches I have come across a lot of info from 2006-2009. Would like to revisit things and see what others are doing now. The main purpose here is to track when any files are changed and if so alert me somehow. The same goes for IDS and hopefully something that can reside on same server? Since some of these are small scale projects I would prefer opensource/free solutions that are really effective. Although I would still like to hear of other alternatives if someone has the experience and the cost can be justified.

• The best software for users internet usage

  - by nikospkrk

  Hi, We are a small business using a Vigor 2820 as the internet router, and we'd like to install a software that could report any internet usage from our users. I already tried the "official" software made by Draytek called "SmartMonitor", but is reliability is a real issue as it doesn't seem to keep capturing packets after working 3 to 6hours (randomly), whereas Wireshark keeps capturing packets after that amount of time. As I'm really fed up with this tool, I'm looking for other solutions but I still want the same features: users statistics, websites ranking, users traffic, ... I already enabled the port mirroring feature, so it would be perfect if you could suggest me a port mirroring-based software (ideally freeware). I thought I had found the good one with Etherscout, but it just doesn't launch. I am even open to a tool that would "just" make some reports based on Wireshark captured files (*.pcap). Thank you for any of your suggestion, Nicolas.

• FTP Issue when connecting to a debian machine from windows

  - by erin c

  I have a .net application which copies bunch of files to a specific FTP folder on a debian machine on periodical basis, ftp folder has 755 mod, owner of the directory is the ftp username that I authenticate in .net application. So far I tested this application with bunch of debian boxes, my initial attempts generally fail with following message if I try it with a debian machine that I haven't tried it before: "remote server returned an error 550 File unavailable" When I see this error, I log onto another debian machine on my network, and I try FTP'ing the debian box that returns the error message from command line. I generally "put" a very small file to the folder in question, right after that windows application starts copying files successfully via FTP. It is as if my command line ftp operation fixes the problem and makes debian compatible with my .net application. I checked permissions before and after the problem, it doesn't look like what I did changed anything, I am at loss understanding why this problem occurs and why it is fixed with my silly hack. Can anybody tell me where to look at next to fix this extremely annoying issue?

• Windows 7 x64 CD to MP3 ripper

  - by marc_s

  I'm trying to find a good, simple CD-to-MP3 ripper to copy my physical CD's to my computer's hard disk. I'm running Windows 7 Professional x64 - and that appears to be a major problem. All the "usual" free- and shareware tools I've tried (CD-to-MP3, Visual MP3 and quite a few more) seem to have trouble with either 64-bit Windows, or with my HP CD/DVD built into my HP Compaq Elite 8100 machine. Does anyone have any good recommendations? I don't want to install a monster like iTunes - something really clean, small, simple would be fine. Free- or Shareware - if it works reliably and with good quality output, I'll be happy to register! Any hints are welcome!

• Should a sysadmin contractor charge overtime for off-peak hours?

  - by Jakobud

  This is not necessarily a server-related question, but more of a system admin question that I think would related to many on SF. I'm doing Sysadmin/IT consulting for a small company. I only work about 3 days a week for them on average. If a server goes down or something like that during off hours (nights, weekends, 3am, etc) and they need it fixed during those time periods, should I be charging overtime for that? I would I not be justified in charging overtime until I've logged 40 hours for the week? Perhaps calling it overtime isn't the best name. I guess maybe its better to call it an off-peak hourly rate. Anyways I just was curious what other consultants did in these circumstances.

• Good 1U Rack Firewall

  - by AX1

  Hello, I'm trying to find a good 1U rack firewall at a reasonable price. Most pricing is completely out of space (thousands of dollars? Why?). I don't want to list all features I need/want (there are too many variations but I don't care about most of them) - I'm just looking for something simple and not overly expensive. I've looked at the WatchGuard XTM 505 which is more reasonably priced -- are there any other firewalls in that range or even less expensive that are good for a small company?

• Continued title numbering

  - by mrg

  Let's assume we have a small Word document containing: First Title On Level A Lorem ipsum .. Title On Level B Lorem ipsum .. Second Title On Level A Lorem ipsum .. What I would like to achive is the following: 1. First Title On Level A Lorem ipsum .. 1.1 Title On Level B Lorem ipsum .. 2. Second Title On Level A Lorem ipsum .. I can't set this up by simply adding numbering to the title styles, because that only adds one number to the title without support for the x.y number format.

• Should I upgrade Exchange 2003 or just upgrade the hardware?

  - by JohnyD

  My organization currently has a 4 y/o Exchange 2003 email server (32-bit, Intel Pentium D @ 3GHz, 3GB RAM). It's run very well over the past 4 years but it is time to upgrade its hardware. This server would handle email for approximately 30 clients, a few OWA users with iPhones. My (somewhat ambiguous) question is, when I receive the new hardware should I build out a new Exchange 2003 deployment or should I look at Exchange 2007 / 2010? I've heard that Exchange 2010 requires Sharepoint 2010 (which I am currently not running). Are there benefits that a small-medium sized business can or can't do without? Am I making a horrible mistake staying with antiquated software? Other details: Exchange 2003 (v6.5 + SP2) single front-end server All opinions and thoughts are very much appreciated.

• File doesn't exist in Linux although it's located in Terminal

  - by Mazen Ayman

  I'm a bit new to unix/linux environment, but I have a small problem. I'm using "locate" to find the path of a file I need, it gives me the path for it, but the file doesn't exist in that path, like that: locate test1.txt /home/user/test files/text1.txt /home/user/test1.txt~ "test files" directory is where I was keeping the file and I copied it to the home directory once but I deleted it, no idea what it keeps telling me there is still a tmp file for it. it worth mentioning that I used the command: locate test1.txt~ |xargs -n1 rm to remove that tmp file, but maybe that what caused the problem. I tried to show hidden files, and check for temp files, didn't find it either. any clue what happened?

• I can't launch any Win8 apps after upgrading to Windows 8.1

  - by locka

  I just upgraded to 8.1 and now none of the Metro apps start. The issue is that if I start any metro app, including the Store and PC Settings they immediately fail. The classic desktop is fine, as are standard programs, it's just the metro apps. If I look in the system event log I see errors like this: *Activation of application winstore_cw5n1h2txyewy!Windows.Store failed with error: This application does not support the contract specified or is not installed. See the Microsoft-Windows-TWinUI/Operational log for additional information.* In addition the tiles in metro have a small cross icon on them: I suspect that my Live ID (which I somehow managed to skip during update) is not set properly and consequently none of the online stuff works. But how do I fix this? I can't start PC settings, I can't start store. I see no way in the classic desktop of setting these things. I don't want to have to reinstall for this. Is there a simple fix?

• Installing Software from a CD onto a Netbook

  - by Jonathan Sampson

  I apologize if this question has come up before - I can't seem to find it. Tonight my wife and I purchased a small samsung netbook and have been enjoying it for a light-weight solution around the house. My wife has a game she loves to play that was installed on her last laptop, but we'd like to put it on the netbook. The problem is, there's no cd-drive on the netbook and the game must be installed from a CD. What other ways can I install software from a CD onto the netbook lacking a local cd-drive on the device itself? I would prefer to not have to create image files, and mount virtual drives, etc.

• Does an unmanaged 4/8-port GBit Ethernet switch with a GBIC port exist?

  - by Aaron Digulla

  I'm looking for a simple unmanaged switch with 4-8 GBit Ethernet ports and a fiber port (either as a GBIC slot or pre-installed with a 1000BASE-SX port). Does something like that exist? [EDIT] I want to connect to places in my home without drilling large holes though the floors. Therefore, I'm looking for a cheap way to connect two GBit switches via fiber. I tried with a media converter (GBit <- multimode fiber) but that costs about 50% throughput. So I was hoping that there is a cheap, small GBit switch which has a GBIC slot). All I found so far are very expensive managed switches with 12 or 24 ports for industry use.

• Cropping a PDF File's Margin During Printing

  - by JavaMan

  I'm using the free Acrobat Reader to print out some pdf documents having very large top/bottom/left/right margins. I want to remove the margins (which are wasting too much space and making the fonts too small). I used to use Acrobat (the paid version having edit features) to crop the src pdf file manually. But since it is an old version it does not support new pdf format and I don't want to upgrade for such a simple use. Is there any free way to crop/remove unwanted white margins from the printed pdf? I am thinking to print the pdf files to a PDF Printer like the Bullzip PDF Printer and enlarge the output file manually so as to remove any white margin. But there does not seem to be such a feature in Bullzip PDF Printer. Is there any other virtual printer software that can be used for this purpose?

• Automatically delete old files from a specified folder?

  - by davr

  I want to set up an automatic task that will automatically delete files older than X days from a specific folder. I'd prefer to do it without having to install any 3rd party software, but I'll be ok if it's a very small and simple utility. I want this to force me to keep my files organized. I am setting my browser to download to a standard folder, and then with this script to automatically delete files older than a week, I will be forced to move & organize downloaded files I want to keep.

• 1Gigabit vs 1.25Gibabit mismatch

  - by Joel Coel

  I need to re-connect the network to a small old outbuilding that hasn't been used in several years. I have to use the existing 62.5um multi-mode fiber run. This end of the fiber is already connected. For the end in the building, I was looking at this pair: http://www.tp-link.com/products/productDetails.asp?class=switch&content=spe&pmodel=TL-SM311LM http://www.tp-link.com/products/productDetails.asp?class=&content=spe&pmodel=TL-SL2210WEB If you look at the sfp first (first link), it's listed at 1.25Gpbs. That's odd, because IIRC the fiber should really only do 1Gbps. It's also supposed to work with the switch I posted (2nd link), but the gbic port on the switch also only shows 1Gbps. What am I missing here?

• Nginx Static Content Server Maxing Out?

  - by Harry

  I use nginx to serve the static content for a decently busy website of mine. I have the logging disabled, and 4 worker processes enabled with 5,000 connections per worker (which should yield a max connection limit of 20,000. The server is only operating at about 10% CPU usage and 50% ram, but it's very laggy, and sometimes nginx is so slow to respond to the requests, it times out. For a small number of connections, it's fine, but once any load starts occurring (~2,500 connections), it backs up and bogs down. Is there any other bottlenecks or limits that I might be hitting? This is a FreeBSD server, and all the static files are located locally (not NFS). The NIC is an unmetered gigabit, and it's only using around 75 megabit. Any insight would be appreciated. Thanks.

• Automatically encrypting incoming email

  - by user16067

  I have a small website and would like to encrypt incoming email using gpg. Is there a way to force sendmail to check email and encrypt it if its not already encrypted? I'm using GPG on a linux server. Thanks [added]Someone asked what I hope to accomplish. My intent is for the users of the email to become more familiar with seeing thier own email encrypted and losing that fear of the unknown. The side benefit is that the email can't be looked at later down the road. If the email isn't encrypted on its way in, I'm unable to do anything about it. I'm assuming most email would be nosed around with once its already on my hard drive, so GPG would protect against those issues.

• How can I share a video file during a webinar?

  - by Brien Malone

  Here is the scenario: I have a number of remote employees around the globe. I want to have a video chatting session. No problem there. Halfway through, I want to shut off all camera video feeds and simulcast (synchronous) a training video to my team. How do I do this? We have tried office communicator, but the frame rate was awful and no audio. Adobe Connect had similar trouble. In both cases we were limited by the main office's small internet pipe, but it is clear that video delivered by shared desktop is not a good solution.

• Stop a particular key getting captured by rdesktop

  - by user18151

  Hello, I want F12 to be not capture by my rdesktop while in fullscreen, so that I can do whatever stuff I'm doing on my remote Windows computer, but pressing F12 would bring down yakuake, and I can type down my commands, or use vim etc for whatever I'm doing. Is there any possible way to do this? I tried playing with keymaps, but that didn't help. I set F12 to inhibit, but that seems to have stopped sending F12 altogether, rather than let gnome catch it and let yakuake pop up. Would be really grateful for answers. I am ready to do my homework, if someone could please just give me pointers etc. Thanks :). Sidenote: My current arranement stems from my large monitor in lab, and small personal laptop monitor, and the laptop has Windows 7. My lab computer has Linux, on which I do my coding work.

• Block P2P traffic on a Linksys router WRT54G with Tomato firmware

  - by Kami

  I'm running a small wireless network (6 to 10 users) on a Linksys WRT54G with Tomato firmware sharing an Internet connection. I don't want the users to download files with BitTorrent (mainly used) and other P2P apps. I've also found some solutions about lowering P2P traffic priority using QoS. I really need to ban P2P traffic. Does anyone know how to setup some rules to deny that kind of traffic? I've tried to setup an Access Restriction Rule: However it's not working at all.

• Postfix count relayed messages per user

  - by Martino Dino

  I would like to know if it's possible to count the outgoing (relayed) messages on a per user basis in postfix. I'm managing a small commercial SMTP relay and decided that it would be nice to have a detailed daily report on how much mail a single user have sent (and eventually enforce some limits) possibly in realtime. I've looked almost everywhere and started to think that writing my own milter would be the way to go... Are you aware of anything that already exists for postfix that can count and report relayed mail for authenticated users (a script, milter or whatever)?
