• Accessing to shared folders with OpenVPN

  - by Ergec

  This is my first attempt to configure a vpn so I have very little knowledge about this. Network where centos server is having local IPs 192.168.123.* Network where windows machine is having local IPs 192.168.1.* I installed and configured my openpvn server on centos 5 and client on a windows machine. Generated all keys, certificates e.t.c and transferred them to client and I'm able to connect to server. Below there is a screenshot of the client log. Also on server side I can also see incoming packets with this command tcpdump -n port 1723 So I assume I did most of the things correct. But still when I try to open shared folders using \\192.168.123.33 or \\network-name I can't access folders

• VPN between Cisco ASA 5505 AND Sonicwall SOHO3

  - by user41451

  Hello. I am trying to establish a site-to-site VPN tunnel between an old SOHO3 and an ASA 5505. The ASA has a static IP and the SOHO3 is dynamic. I have tried everything my limited knowledge lets me and need some advice on how to proceed! Phase 1 (according to the ASA logs) completes - followed by a message saying "All IPSec SA proposals found unacceptable!" so I guess the settings between the two don't match. I have played with various combinations and nothing seems to work - I am overlooking something, just not sure what it is! Any help would be appreciated.

• I run about 100 small traffic websites, what host would you recommend (expansion is planned)?

  - by MALON

  I know there are plenty of suggestions like asmallorange, linode, etc, but how well do these apply to someone who is running 100 sites? Traffic can be anywhere from zero hits a month up to about 1,000. The host I'm using right now doesn't allow access to httpd.conf or other important apache features. If I had to guess, it seems like Linode or other services like it are right up my alley, however, I am not great with linux. I can get by alright in Ubuntu, but that's about it. Will this knowledge be enough to get by with Linode? What about domain name transfers? The way it works now for me is if someone has an existing site, I ask them to get the domain transfer code and then I send the domain name xfer code to my current host and they take care of the rest. Does Linode take care of domain name transfers? How do I do it?

• Hosting-why should I pay? [on hold]

  - by user196919

  Can I avoid, eliminate or neutralize propagation? Hours of research for a first-time unregistered domain returned the usual suspects ("Oneandblank", "GoBlanky", "BlankCow", "HostBlank-or" and others)all with 24-72hr or more. Would a roll-your-own, inhouse SHO Linux/Winserver box help? Thank you so much! edit; navigating SF for my first time I now notice the "professionals" air and feel to the comments. Although I feel justified for being here(armed with directly relevant, well-rounded knowledge/proficiency/experience)I apologize for diving in headlong without proper post etiquette or correct placement. I envy each of you and hope to gain my own inviolable foothold in the coming years.

• When connected to VPN through Windows 7 running under OS X via VMWare Fusion, does traffic from the OS X side go through the VPN?

  - by user1202747

  I only have a rudimentary knowledge of VPNs. My understanding is that, in most network configurations, when a client is connected remotely to a VPN server, all network traffic passes through the VPN server before going to the client, and all data coming from the client passes through the VPN server before going out over the wider Internet. I run Windows 7 using VMWare Fusion under OS X Lion. If I access a web page in Safari, say, on the OS X side of things, does that traffic pass through the VPN server? Or does it bypass it because the two OS's are regarded as separate network devices by my LAN? I would appreciate any insight anyone can provide. Thanks.

• Clicking on a link in Chrome opens up Notepad

  - by jonsca

  I'm currently using Chrome 21.0.1180.89 on Windows 7, but I have noticed this behavior in other versions before. Probably about one time in a hundred, I will click on a link on a website and an instance of Notepad will open up with a blank page rather than the browser going to the link. To my knowledge, I have no malware or viruses on the machine that could be causing this. It's a minor annoyance, so I'm not very concerned about it, but I'm wondering if there could be a MIME type that's set wrong by default in the browser?

• Seeking easy to use Setup creator with logic and ability to write registry keys

  - by Mawg

  I want to create a Setup to install my application. It as to be able to do the following: ask a question (maybe 2 radio buttons?) and, depending on the reply, copy one of 2 DLLs to the Windows directory and invoke regsvr to register the DLL write some registry keys I would code my own program to do this, but I don't have enough knowledge of the different versions of Windows (XP, Vista, 7, etc) and 32/64 bit, registry layout, or permissions like UAC, etc So, it seems to me that it would be easier to use a Setup generator which has been around for a while and already handles all of this stuff. I went to my favorite site for free stuff and found this page. However, the programs mentioned there are either too simplistic or have too steep a learning curve for me. Can anyone recommend a Goldilocks solution which does what I mentioned in those two bullet points while taking into account all Windows versions, 32/64 bit, non-admin accounts, etc?

• What are the methods of separating network spaces in a LAN?

  - by dash17291

  Please detail me the methods. My thoughts: put the servers in separate (sub)networks the servers are forced to go through the firewall but no NAT is required assign more IP addresses to the internal interface of the server choosing gateway addresses from the clients and servers IP address ranges split DNS Netfilter/{iptables, ipset} could be heavily involved, I'm talking about Linux servers. See for example: Destination NAT Onto the Same Network from internal clients Please do not explain what is NAT or DNS. This is a theoretical question, but my poor English knowledge prevent me to describe it in a fancy fashion.

• Does "I securely erased my drive" really work with Truecrypt partitions?

  - by TheLQ

  When you look at Truecrypt's Plausible Deniability page it says that one of the reasons for partition with solely random data is that you securely erased your drive. But what about the partition table with full disk encryption? How can you explain why the partition table says there's a partition of unknown type (With my limited knowledge of partition tables I think that they store all the partition filesystem types) and with solely random data? It seems that if your going to securely erase the drive you would destroy everything, including the partition table. And even if you just wiped the partition, the partition table would still say that the partition was originally NTFS, which it isn't anymore. Does the "I securely erased my drive" excuse still work here? (Note: I know that there's hidden truecrypt volumes, but I'm avoiding them due to the high risk of data loss)

• How to make vim display unicode

  - by Yitzchak

  I am trying to work with a utf-8 encoded xml file in vim 7.3 running on ubuntu. ASCII characters display normally but vim gives me gibberish instead of the unicode characters. After trying the following, I've reached the limits of my knowledge: 1) Checked that unicode was enabled by running set termencoding?. Output was termencoding=utf-8. 2) I installed the script from here (vim.org/scripts) 3) moved my ~/.vimrc file into ~/.vim 4) moved it back into ~ 5) followed the instructions in the accepted answer to this question. Is there some other variable I'm supposed to set? I know my system has the fonts I need. Update: Issue seems to be limited to html files for some reason.

• Network flooded with seemingly empty packets

  - by Adam Particka

  Let me preface this with the fact that I'm just a web developer at my company with little networking knowledge. Earlier today there was a department that lost all of their network connections so I popped open Wireshark and observed the influx of packets to my machine. There was normal traffic (ARP requests, etc.) coming in at ~50 packets every second. Then all of a sudden the log was flooded with packets arriving ~5000 a second. It looks as though they all contain the same data, just a looped sequence. We have someone here looking at it but I thought I would ask if anyone had seen anything like this before. Here's a selection from one of the captures in Wireshark. http://www.cloudshark.org/captures/06f950725c74

• Features of Emacs that are complementary to Vim?

  - by redacted

  I've been using Vim extensively for a while now, and I really enjoy working with it. However, I keep reading praises for Emacs. I've decided to take a look at Emacs to round out my knowledge of the Unix editors (not to mention Emacs keybindings are used extensively). But! I'm happy doing most of my daily work in Vim. So ideally what I'd like is to look at (apart from basics) are the gaps that Emacs can fill, or things that it can just do better than Vim. I suppose the canonical example is Lisp/Scheme coding in Emacs versus Vim. Where would you start tinkering with Emacs to really appreciate its power, and to get a good idea of how its approach to editing differs from Vim, and how the editors can complement each other? What would be a good introduction in the same vein?

• Optimal partition setup for Windows 7 on SSD

  - by Mike C.

  Hello, I'm setting up my system with Windows 7 right now, with knowledge that I am going to be getting a SSD in the future. What optimizations/setup should I do now to make a smoother transition in the future? Should I created two partitions - one for the OS and one for the data? Assuming this is the case, I would be able to easily ghost my OS partition onto the SSD in the future. If so, what should go on the OS drive besides the OS? Program files? If I install games or Visual Studio, should it go on the OS drive or the data drive? I can see the SSD filling up fast if I install all my program files on there. I've seen a few posts where people talk about leaving a portion of the SSD unformatted - is this something I should do? Thanks!

• Firefox: combine bookmarks toolbar and tabbar

  - by horsedrowner

  I am looking for a way to 'minify' the Firefox UI by combining the bookmarks toolbar with the tabbar. The easiest way I could see this done, is by simply moving the Bookmarks left of the tabs on the tabbar. I do not have the knowledge of writing my own userChrome.css styles, but it seems possible to do it this way. Another more difficult way to do this, would be by making it work similar to Windows 7's taskbar. What I mean by this, is to have a bookmark toolbar, and clicking on a bookmark would turn it into a tab, just like clicking an icon in the taskbar in Windows 7 would turn that into a 'program'. Ultimately, it comes down to this: by default, you have two toolbars: a bookmarks toolbar and a tabbar. I would like to combine these into one toolbar.

• WIFI connection interfering with Windows Server 2003 Active Directory domain. (How to debug?)

  - by Vinko Vrsalovic

  RELATED: This question has led me to ask this one. I had to change our unnamed crappy ADSL router to a crappy Comtrend CT-5361 WiFi router, now every WiFi connection to the domain doesn't work correctly: Joining the domain is impossible (see related question) Logging into the domain takes ages Authentication usually fails Question: How to debug this and pinpoint the exact problem? I have no enough knowledge on either WiFi networks or on Active Directory to know which connections are made at which stages nor how to check what's happening at the wireless level to compare what should happen to what is happening. I'm looking for resources to learn what should be happening and tools to detect what is actually happening (I expect a sniffer should be enough, but if there are better, more specialized tools, that'd be great).

• Point IP to site for testing before delegation?

  - by cosmicbdog

  I'm migrating to a new server and would like to test before redelegating the domain over. I have some familiarity with setting up apache virtual hosts, but limited knowledge. How can I go about setting this up? My server already has a domain delegated to the server, and the IP by default has been setup to point to that. I've been told I can just add an entry to /etc/hosts/ which I haven't been able to understand what I can add in there to make this work. Any pointers would be greatly appreciated!

• Multiple EyeFinity Display groups

  - by Shinrai

  Is it possible with an EyeFinity enabled card to make multiple display groups at once? I was playing with a FirePro 2460 and while a 4x1 or 2x2 display group works quite nicely, if I make a 2x1 display group and then select one of the other displays to try to make a second 2x1 display group, it disables the first one. Is there any way to circumvent this behavior and set up two separate spans on the same card? Additionally, can you set up distinct display groups if they're on different cards? I will have the opportunity to test several of these cards in one machine very shortly, but I'm curious if anyone has any experience. EDIT: I can confirm that you can make multiple spans on multiple cards (as long as they don't cross cards, obviously) (If the answers are different for FirePro/FireMV cards and Radeon cards, that is helpful and relevant knowledge - I doubt it, though.)

• JBoss view active user sessions

  - by user49080

  We have a JBoss server with a single J2EE on it. I wish to find out who are the current active users using that application. Does JBoss give me any utilities that lets me view those existing sessions? (NOT the count, but who all are logged in) The question is kinda lame, but so is my JBoss knowledge :) I checked the JBoss community, but it only had a couple of relative unanswered questions there. The information i'm looking for would help me in maintenance cycles. I do not wish to reboot the system when users are still using it. We also need to keep a track of any illegal activities on our server. Hence the requirement. Would appreciate any pointers :) Regards, Abhi

• Tomcat SSL integration issue

  - by small_ticket

  Hi all, I've bought a wildcard ssl certificate from a company, i sent them the csr file and they send me two certificate files namely CA.txt and com_sertificate. I've searched on web and find some tutorials about tomcat and ssl but i can not accomplish with these two files. All that tutorials mention about different files that i don't have. (I asked about this process to the company that i bought certificates but they said they don't have any knowledge about tomcat integration) Is there anyone that has an idea about this? p.s I'm using ubuntu 8.04 server, Java 1.6 and tomcat 6

• A unique identifier for a Domain

  - by jchoover

  I asked a question over on StackOverflow and was directed to ask a related one here to see if I could get any additional input. Basically, I am looking to have my application aware of what domain it's running under, if any at all. (I want to expose certain debugging facilities only in house, and due to our deployment model it isn't possible to have a different build.) Since I am over paranoid, I didn't want to just rely on the domain name to ensure we are in house. As such I noted the DOMAIN_CONTROLLER_INFO (http://msdn.microsoft.com/en-us/library/ms675912(v=vs.85).aspx ) returned from DsGetDcName (http://msdn.microsoft.com/en-us/library/ms675983(v=vs.85).aspx) has a GUID associated with it, however I can find little if any information on it. I am assuming this GUID is generated at the time the first DC in a domain is created, and that it would live on for the life of the domain. Does anyone else have any inner knowledge and would be kind enough to confirm or deny my assumptions?

• StorageWorks MSA60 and other storage related questions

  - by Mejmo

  Hi, I do not have deeper knowledge of the storage area, sorry for asking evidently stupid questions :) We are thinking about getting HP StorageWorks MSA60 for storing our VM. Do we need another DL server with controller so that we could use iSCSI ? Do we need to get some P800 controller for doing that? I cannot imagine how it is connected together actually ... MSA60-DLserver with p800 controller and servers that are running VM connected with iSCSI to this DL server ? Or MSA60 directly supports iSCSI so the DL server is not necessary ? What is inside this MSA60? Is it possible to install there OS ? Thank you.

• Who should own /var/www? [closed]

  - by John

  Possible Duplicate: How should I structure my users/groups/permissions for a web server? I've seen a few answers to this on the internet, but I'm looking for a definitive answer. I have a new Ubuntu 12.04 LTS server with LAMP. Apache is set to run as "www-data" and /var/www is set as having "root" as the owner and "root" as the group. The permissions for /var/www are "drwxr-xr-x" which I believe translates to 755 numerically. I know that /var/www should not be owned by "www-data" because then buggy/malicious code could have a field day. However, should I keep it as root:root (inconvenient) or should I change it to ubuntu:ubuntu, the default user that Ubuntu preconfigures for you to log in with? Should the permissions remain at 755? I've been administrating systems for a while with no big security issues, but I'm trying to get really serious about security, double-check everything, and make sure that there are no gaps in my knowledge.

• Connect a linux server to network and access it from another computer browser

  - by user1732451

  I had a server in a hosting company and I took it home. I need to connect him to a local network (not wifi) and access to the server from another computer in the network via browser, like I did it when it was in the hosting company. I don't have any knowledge in linux, I just know how to type in the command line :) I thinks all the IP configuration of the server is one big mess, because it passed from more then one hosting company to another... I tried a lot of tutorials that I found in the web, but nothing works - mainly because I don't know how to check if I did something wrong. I just need to know how to connect to local network ( D-Link router) and then access the server from another computer browser. thanks update: the server os is: CentOS release 4.8 (Final)

• Social Shopping

  - by David Dorf

  I've written about various breeds of social shopping in the past, so I decided to give some thought into a categorization with examples. Below I've listed the different types of social shopping I've observed and some companies that support them. Comments and Ratings -- Commenting on products has been around almost as long as e-commerce. Two popular players in this space are BazaarVoice and PowerReviews. Most shoppers prefer relying on peer reviews rather than retailer descriptions, so the influence over sales is very strong. f-commerce -- A new term that was sure to rear its ugly head when retailers started allowing shopping on Facebook, And its all Elastic Path and Alvenda's fault! Co-shopping -- Retailers like Wet Seal are enabling multiple people to shop together online. This is particularly applicable to fashion, where the real-time exchange of opinions is important. I actually tried this with a co-worker and its pretty cool. Bragging -- Blippy is Twitter for shoppers, allowing purchases to be "tweeted" so you can keep up with your friends. I get alerted when friends download music or apps from iTunes because chances are I'll be interested as well. This covert influence is one-up'ed by Snatter, a service that gives people discounts for tweeting or posting promotions from retailers. This is the petri dish of viral marketing. Advice -- Combine the bragging of Blippy and the opinions from BazaarVoice and you'd get ShopSocially, a social network dedicated to spreading product knowledge amongst informed shoppers. I'm sure if I gave it more thought, a few more types would come to mind, but I've got to get back to work. Now is not the time to be blogging at Oracle!
