• FTP error when doing file transfer

  - by Ernie

  I'm running vsftpd version 3.0.2 over FTPeS, and I'm having a bit of trouble with file transfers. It seems to work fine when I'm on the LAN, but not from an external IP address. I have the control port and data ports open on my server's software firewall and my router's firewall. When I'm using the service from an external IP address, it seems like sometimes a file transfer will complete, but it times out and I always get the client error: "426 Failure writing network stream". I've tried several clients. I'm thinking there is some sort of data sabotage either at the router or some server policy; maybe because I'm using passive ftp? Suggestions?

• iPhone VPN to iTunes Home Sharing

  - by Philip Crumpton

  my goal is to set up a VPN on a Windows machine that contains my iTunes library then connect to that VPN with my iPhone and be able to utilize Home Sharing remotely. I have read that this can easily be set up if the iTunes library is on a Mac (Network Beacon and YazSoft ShareTool are two products I quickly found). I can't find anyone who has had success on a Windows machine, though. In my thinking, there are two options (aside from buying a Mac): 1.) Existing utility that takes care of this for me (like the Mac-only options listed above) and is compatible with iPhone (Hamachi is NOT compatible with iPhone VPN) 2.) Manually configure a VPN to allow Bonjour multicast (can't find any information on this) FYI my router is a Linksys WRT54GL running Tomato 1.28

• configure vpn so that it is not the preferred route

  - by pstanton

  Hi all, I recently re-installed XP on my PC. I had a vpn set up on the old system and remember being advised to change one setting so that it wasn't the preferred route for all network traffic. This was ideal as only connections to the target network would be made through the vpn and all normal traffic would go through the regular path unmolested. i remember thinking "why isn't this the default setting!?". now i've formatted my drive and lost the config for that vpn (besides host, username, passwd). does anyone know of the setting i'm referring to? thanks, paul.

• If i make a mail server can i send bulk email?

  - by Jake Smith

  I work for a small company and we have fallen into the fad of "email campains" a.k.a Junk mail. So far the company has gotten a subscriber list from our website, and paid a good chunk of change for a emailer program. The problem is, Our list has close to 4,000 people on it and growing. with gmail only allowing 100 emails per account through on SMTP and I am on a tight budget so I cant hire anyone else. I was thinking of doing a dedicated mail server off of the website server we have running in the office. Is it possible? to make emails on your own server, and then send it through your own SMTP? if it is, what software would I need and is if free or low cost at least. We run a WAMP server, i set it up just for information, but i could switch it to lamp or whatever if need be. Thank you for your time and youre answers

• Windows: How to add batch-script action to Right Click menu

  - by ervingsb

  I have a few programs that creates temp files or backup files or similar files that are not important. For example, GVim for Windows by default creates a backup file in filename.txt~. I sometimes need to clean up a dir and remove all these files. I have made a simple .bat file for this. However, it is cumbersome to have to start up cmd, navigate to the folder, run the script. Especially since this is a script that I would like to run often on various folders. And I do not want to copy the script to multiple folders, as this would be a maintenance nightmare. So, I was thinking, that the best solution would be to add a Right Click menu item that allows me to run the script. So that I can right click on a folder in Explorer and click Cleanup and then have my script run on this folder. So my question is: How do I add a right click menu action that runs a custom batch script?

• Win2008 - restrict VPN user permissions

  - by Sebas

  Windows 2008 R2 SP1 Foundations file server with no AD, only workgroup sharing some folders, and now a RRAS server. Shared folders are open to everyone in the office (XPs and Sevens) without accounts/passwords, but I was thinking about partially limiting access to the new "VPNuser" account. I'm new to Windows Server and its permissions settings: I thought about denying access to vpnuser through NTFS rights in some folders. It doesn't work, but now I'm guessing that the vpnuser is not considered as a logged user (doesn't appear as such) and is considered a "guest", like the rest of people connecting in the office. I say that because of this: http://social.technet.microsoft.com/Forums/windowsserver/en-US/ff6d3726-ff41-4d3f-9d97-5361af0206dd/vpn-users-on-server-shows-as-guest?forum=winserverNIS Also, because when I create a txt file using the VPN connection, owner field shows in description as "guest". Am I right? How can I set different rights for the VPNuser from the rest of "guest" users in the office?

• AWS: Should my EC2 and RDS instances be in the same Availability Zone?

  - by DOOManiac

  I just noticed that all of our EC2 instances are in zone us-west-2b, but our Multi-AZ RDS instance is in us-west-2a. Performance-wise everything seems to be okay, and it will be a hassle to "move" the instances to one place since you have to stop and re-create them all. However if either of the two zones goes down when we will have some downtime; if everything is in one zone then at least we have a higher chance of not being in the zone that has downtime... Is this something worth fixing, or am I over-thinking it? (I was about to purchase some EC2 Reserved Instances, which are tied to specific AZs, so I wanted to make sure before going through with it) Thanks!

• Is a computer's DRAM size not as important once we get a Solid State Drive?

  - by Jian Lin

  I am thinking of getting a Dell X11 netbook, and it can go up to 8GB of DRAM, together with a 256GB Solid State Drive. So in that case, it can handle quite a bit of Virtual PC running Linux, and Win XP, etc. But is the 8GB of RAM not so important any more? Won't 2GB or 4GB be quite good if a Solid State Drive is used? I think the most worrying thing is that the memory is not enough and the less often used data is swapped to the pagefile on hard disk and it will become really slow, but with an SSD drive, the problem is a lot less of a concern? Is there a comparison as to, if DRAM speed is n, then SSD drive speed is how many n and hard disk speed is how many n just as a ball park comparison?

• web spidering/crawling, can i do it or just search engines?

  - by bboyreason

  i already had a question answered about web-scraping with wget. but as i read a little more, i realize i may be looking for a web-crawling program. particularly the part about web-crawlers being able to get specific data like links or, in my case, products. all of the products on my site have the following naming convention, website.com/uniqueAlphaNumericID.html as far as i know, no dynamic content generation is being used and only one page per one item in the above format. should i just be thinking about: wget website.com | grep *.html or should i be looking into spiders/crawlers?

• Digitizing notes?

  - by Nimmy Lebby

  I want to digitize my note taking. I was looking into using tablets or something of that sort but I feel that it would be too much of a challenge to type instead of actually writing my notes during meetings. That got me thinking into looking into something like LiveScribe. It looks neat but I don't know how it would work in the real world. How does OCR work with something like smart pens? How is the desktop applications? Any experience? Does anyone have an alternative suggestions? Positives and negatives? Any advice would be helpful.

• How to connect a remote IP Phone to our VOIP Network?

  - by Mistiry

  We have an IP phone system in our office, and about 8 VoIP phones running on the system. We have a remote worker, who is literally states away. We'd like to connect his phone to our VoIP network, so that he has a business phone and an extension to which we could transfer calls. I was thinking, although I don't know for sure, that a pair of Cisco routers could be used in some way to make this work. I imagine a VPN solution, where I have one router connected to the phone network and the other router connected to the remote phone. Then have a site-to-site VPN set up so that the remote router... And that's where I'm stuck. I know the remote router will need to use the DHCP server of the phone system. I've never set up something like this, so I am seeking the help of the community here. What is the best way to get this remote VoIP phone RELIABLY connected to our internal VoIP network?

• Logging upload attempt with proftpd

  - by Amit Sonnenschein

  I have a logging server that i use with external hardware, the idea is that a special hardware is uploading logs about it's operation every few hours and from the server i can do whatever i need to do with the information, the old server was getting a bit too old and i've moved to a new one, i've install lamp,proftpd and ssh (just the same as i had on the old server). now for some reason the logs are not being uploaded and i don't know why. the hardware uses a direct ftp access - i've the proftpd.log and saw that the connection is not being rejected (just to make sure i didn't make a mistake with the user/pass) my problem is that for some reason the upload itself is failing... it might be due to wrong path (as it's hard coded in the hardware) but i can't really know as proftpd wont give me any details.. i've tried to change the loglevel to "debug" thinking it would give me more information but i don't see any change... is there any other way i can make sure proftpd logs EVERTHING ?

• What are some IT jobs where you don't sit at a desk for 8-10hrs a day?

  - by zippy

  Like a lot of people in IT I sit at a desk for 8-10hrs/day working on stuff that needs to get done "now". That usually means eating unhealthy lunches at my desk, and sometimes dinner too. This does terrible things to your health. I have been trying to work some exercise into the workday but I was thinking it would be great if I worked somewhere where I was exercising all the time (walking around, lifting servers, etc.). Does anyone have a job in IT (or know someone) where you are actually moving around (not sitting) doing something for most of the day?

• Does changing web hosts (changing a domain's nameservers) affect the private nameservers / glue records created under that domain?

  - by Kris

  We currently have a virtual dedicated server with GoDaddy and have 4 domains under it. I ended up creating private nameservers under, say mydomain_a.com, and have ns1.mydomain_a.com and ns2.mydomain_a.com as the nameservers for the other 3 domains. Now, we're thinking of switching web hosts (not domain registrar just the host) which means I have to change mydomain_a.com's nameservers to the new host. Will that affect or mess with the other 3 domains still pointing to ns1.mydomain_a.com and ns2.mydomain_a.com? Will that affect the private nameservers / glue records in anyway? Currently: domain: mydomain_a.com nameservers (GoDaddy): ns1.mydomain_a.com ns2.mydomain_a.com domain: mydomain_b.com nameservers (GoDaddy): ns1.mydomain_a.com ns2.mydomain_a.com After the Change: domain: mydomain_a.com nameservers (Other Host): ns1.some_other_host_ns.com ns2.some_other_host_ns.com This is my Question, Would this be affected? domain: mydomain_b.com nameservers (GoDaddy): ns1.mydomain_a.com ns2.mydomain_a.com

• how to create a simple radio station [on hold]

  - by John

  I've been digging around for ages but not getting very far so any links or tips would be massively appreciated. I want to create a central "radio station" in my home to stream one playlist to any computers pointing their browser to the ip within my internal network. I have an old mini slave mac mini running ubuntu and was originally thinking I could get php and apache to handle this but then quickly realised that of course, php will serve out streaming independently per connection ie no radio station. Are there any servers already built for this sort of behaviour? is shoutcast one of the only versions Thanks, John

• Block a machine from accessing the internet

  - by Simon Rigby

  After some confirmation that I have thinking right in this scenario. We have a number of wired and wireless machines which presently have direct internet access. I also have a Linux (Ubuntu) server which is used as a file server for the network. Essentially I would like to be able to turn internet access on and off for machines. My plan is to block these machines by MAC address at the router. I would then set up a proxy server on the Linux box (ie Squid) so that the machines I wish to restrict can access the internet via the proxy. As I can adjust access via ACLs in squid, I would be able to switch on or off a machines access to the internet without having to further adjust the router's MAC rules. And of course I could go further and create a few scripts to assist with this admin task. Does this seem sound and have I over looked anything? Any help greatly appreciated. Simon.

• Examples of applications where messages are guaranteed to turn up imediately

  - by James Hay

  I'm trying to find an example to show where data is sent from somewhere, whether manually or automatically, and is received IMMEDIATELY by the recipient, (doesn't matter whether we're talking mobile, desktop or whatever). An even better example would be where there were multiple recipients for the same message. It doesn't matter what the data is or the context it's used in, only the immediacy of receiving it. I was thinking that there might be some example in finance and the stock markets, but I haven't been able to find any through googling. IM clients are a great example of this and I think I'm basically looking for examples of applications that communicate over sockets. If anyone works on applications of this nature or knows of particular implementations, can you give me a quick run down of the use case and if it's commercial software the name of the software. This is all basically for research purposes so doesn't have to be particularly detailed. If anyone can help, thanks.

• Virtual Windows Servers and Pagefile location [closed]

  - by Luke Puplett

  Considering that Windows makes heavy use of the pagefile even with huge amounts of RAM available, is it not best to have this pagefile on the fastest disk possible as close to the virtual systems as possible? I'm thinking, RAM disk. Where I work, storage for VMs is out on a NAS/SAN. I'm worried that so much memory access is having to go across the network! As a side, I think its about time MS got rid of paging and told us to buy more DIMMS. UPDATE So this question has been downvoted??! Accessing a local spindle is C40,000 times slower than a DIMM, so going over the network will be even slower for hard faults. I don't know why I got the downvote, I'm certain that this is an issue unless there's some other mechanism in ESX/HyperV that manages this.

• Sync two external harddrives?

  - by acidzombie24

  A little mishap happened earlier today and i am thinking i should have a copy of my external harddrive since 10% of it is very valuable. What is the best solution to keep two external harddrive in sync? i'll probably use one as regular and maybe use the other only to copy data. The easiest way to keep it in sync is to clear one drive and copy the other but 1T of data will take a long time. Whats a good existing app that will keep them in sync? freeware preferred.

• Can I do an overwrite install of Windows 7 without losing all my apps and data?

  - by Brian Dougan

  My local computer technician installed his store's copy of Window's 7 Premium on my computer. I had been using Window's Vista; but needed the XP component of "7" As part of the price I paid; I have a fully licensed, unopened "7" disc; with all of the drivers included. The technician warned me about the "nag" screen; that asks me to install my licensed copy at any time. Without thinking; I downloaded all of my usual software programs before installing the licensed copy. Here is my question: I hope this won't sound obvious: Will it overwrite my downloads?

• Apache conf for high trafic CMS with backend users?

  - by Annan

  I'm in the situation where a website is going to have a high number of web users and a few backend webmasters. Webmasters will upload images (+other high mem tasks) and this bumps up the memory allocation of the httpd child processes to 100-150mb. In order to stop swapping I'm currently setting MaxClients in httpd.conf to 20. However this lowers maximum simultaneous requests. Will this be a problem when the website goes live? What is the best configuration? Info: Drupal 6, PHP 5, Apache 2.2 (Prefork atm) I'm thinking about Worker MPM, two apache instances or low MaxRequestsPerChild.

• Suggestions for someone wanting to become a Laptop Reseller

  - by Josh B.

  First of all, to give you a little background... I have had my Microsoft A+ for several years now. I used to run a small business repairing Xbox 360 consoles and I am currently a Network Engineer for a company in Ohio. I definitely know my way around a computer. I miss running a small business on the side and I'd like to get something going again. There is a really high demand in my area for Laptops and I was thinking about starting a small Laptop store out of my house. What is the best way to do this? I was assuming that the best way would be to buy barebones systems and build them yourself. If this is the best method, I would be very interested in any resources to get parts and such. Apparently Laptop parts aren't the easiest thing to come by (especially at a good price). Does anyone have any suggestions about how to get something like this going?

• IIS - Script for repeated hacks on a website

  - by dodegaard

  I currently have a site that is armored by ELMAH as its reporting mechanism. Each time someone hits a URL that is incorrect it notifies me or logs to the system. This is annoying for someone fat-fingering the URL with a misspelling but great when a hacker is trying to crack a site of mine. Has anyone ever written a script for IIS 7 on Win 2K8 that blocks an IP based on repeated attempts to hit a website? I've looked at Snort and other IDS systems but if I could get a script that could be linked to my ELMAH system it might be the perfect thing. PowerScript, etc. is what I was thinking. Hints and recommendations are wonderful and if you think a true intrusion detection system is recommended give me your ideas. Thanks in advance.

• Ubuntu+Mono+Postgres+ASP.NET 4.0. No problem?

  - by wreck_of_u

  Would this be ok? I'm an ASP.NET developer and I'm planning to build "portable" web app servers based on Atom D510 mini-ITX. I have ran Ubuntu 10 with MySQL along with a separate IIS machines (win 2k3, 2k8) before with no problems. But now I'm thinking of "packaging" a web/db server into one small, cheap machine. I thought of Ubuntu/Mono/Postgres/ASP.NET, that it would be a good idea but I'm not sure? I have not actually tried it yet. Your thoughts?

• Can I use only a HDMI monitor?

  - by Felix

  I recently found out there are such things as PC monitors with TV capabilities (or TVs that can be PC monitors), and the idea kind of tickles my fancy. I'm thinking of getting one of these gadgets, and if I do, I will connect it to my PC via HDMI (my graphics card has builtin HDMI), so that I also get sound to the TV. The reason for this is because I have a 2.1 sound system which I want to use both on the PC and the TV. Basically, I want the configuration to look like this: Cable --------> TV --> 2.1 Sound System PC --HDMI--> TV --> 2.1 Sound System My question is: can I use a setup like this? Can I not have a classic VGA monitor? Will I be able to see non-graphical interfaces (such as the BIOS, GRUB, a Linux terminal, ...) through HDMI on the TV? I use Windows 7 and Ubuntu.
