• Windows 7 can't find Ubuntu computer by hostname

  - by endolith

  I got a new Windows 7 machine, and was using VNC, SSH etc to connect to my Ubuntu machine, and it worked fine previously connecting to the Ubuntu computer's hostname. Now it doesn't work if I use the machine's hostname, but it does if I use the local IP or DynDNS name. I can also access it from my Android phone using the local hostname over SSH. If I try to connect with SSH to the hostname, it says "Host does not exist". VNC says "Failed to get server address". NX says "no address associated with name", and I don't see it in Windows' "Network" folder. I've rebooted everything. I've turned off Windows firewall. It was working fine a few days ago, but now it's not. How do I figure out what's blocking it? Aha: It probably has something to do with Samba. I reset the Samba configuration the other day, and apparently this can affect it. http://ubuntu-virginia.ubuntuforums.org/showthread.php?t=1558925 I tried commenting out "encrypt passwords = No" as described there, but it still doesn't work.

• What can be a reason for phpMyAdmin login to be not working (not at all, no reaction on submit)?

  - by Ivan

  When I open "http://localhost/phpmyadmin/", enter "root" as the user name and my MySQL root password and press go, then if I was using Firefox, I was getting offered to download index.php file (of a zero length), if I was using Opera 11, it said "Connection closed by remote server". Following recommendations I've removed all packages related to phpMyAdmin, PHP, MySQL and Apache and then reinstalled them step-by step (instead of just issuing apt-get install phpmyadmin and relying on the system to install the whole LAMP stack via dependencies as I've done before). The only change I've got was Firefox to stop offering to download index.php - now when I press Ok to submit my password, it just doesn't show any visible reaction at all. What may the reason be and how to fix it? I use up-to-date Xubuntu 11.04. Reinstalling the whole LAMP stack and phpMyAdmin did not help, neither did removing AppArmor. I've tried to use SQLBuddy instead, but there's exactly the same problem. So, I think, the problem is not in phpMyAdmin but in MySQL, Apache or something. MySQL seems to work if I use command line to access it. Apache & PHP seems to work also, as the login page of phpMyAdmin displays correctly.

• Software RAID 1 Configuration

  - by Corve

  I have created a software RAID 1 quite some while ago and it always seemed to work for me. However I am not completely sure that I have configured everything right and do not have the experience to check so I would be very grateful for some advice or just verification that all seems right so far. I am using Linux Fedora 20 (32 bit with plans to upgrade to 64bit) The RAID 1 should consist of two 1TB SATA hard drives. This is the output of mdadm --detail /dev/md0 /dev/md0: Version : 1.2 Creation Time : Sun Jan 29 11:25:18 2012 Raid Level : raid1 Array Size : 976761424 (931.51 GiB 1000.20 GB) Used Dev Size : 976761424 (931.51 GiB 1000.20 GB) Raid Devices : 2 Total Devices : 1 Persistence : Superblock is persistent Update Time : Sat Jun 7 10:38:09 2014 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 Name : argo:0 (local to host argo) UUID : 1596d0a1:5806e590:c56d0b27:765e3220 Events : 996387 Number Major Minor RaidDevice State 0 0 0 0 removed 1 8 0 1 active sync /dev/sda The RAID is mounted successfully: friedrich@argo:~ ? sudo mount -l | grep md0 /dev/md0 on /mnt/raid type ext4 (rw,relatime,data=ordered) Basically my question are: Why do I only have 1 active device? What does the State removed at bottom mean? Also I noticed some strange error messages that I see on the console on system start and shutdown and always repeating in the background when I switch with Ctrl + Alt + F2: ... ata2: irq_stat 0x00000040 connection status changed ata2: SError: { CommWake DevExch } ata2: COMRESET failed (errno=-32) ata2: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen ata2: irq_stat 0x00000040 connection status changed ata2: SError: { CommWake DevExch } ata2: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen ... Are these errors related to the RAID? Something seems wrong with the SATA devices.. All together the system works (I can read and write to the mounted raid) but I always had these strange errors on startup shutdown (probably always in the background). Thx for your help

• Openvpn - stuck on Connecting

• Failed none and iptables

  - by Michael

  The problem is that when I ssh to my host with putty and enter user name, after that the password prompt delays. Found this is directly related to my iptables and can solve by changing default policy to ACCEPT. If default INPUT policy is ACCEPT, then password prompt is coming immediately. Mar 13 00:05:01 server-ubuntu sshd[6154]: Connection from 192.168.0.10 port 26304 Mar 13 00:05:06 server-ubuntu sshd[6154]: Failed none for acid from 192.168.0.10 port 26304 ssh2 However, if default INPUT policy is DROP, I got slight delay in getting password prompt after I enter username Mar 13 00:07:12 server-ubuntu sshd[6177]: Connection from 192.168.0.10 port 26333 Mar 13 00:07:35 server-ubuntu sshd[6177]: Failed none for acid from 192.168.0.10 port 26333 ssh2 For the second case, I tried to set default policy for FORWARD and OUTPUT chains to ACCEPT, but it didn't help. The only rule in this case is: -A INPUT -i eth1 -m mac --mac-source 00:26:XX:XX:XX:XX -j ACCEPT 00:26:XX:XX:XX:XX is the mac address from which I am trying to ssh to server's LAN(eth1). I'm sure there has to be some rule, which I can use while default INPUT chain policy is DENY in order to get password prompt immediately. I realize that the error message in the log is something normal and part of some verification procedure.

• choosing hosting for custom ecommerce site, shared, dedicated, what to look for?

  - by spirytus

  Hi, I have (almost) developed website for my client and now need to decide on hosting. Most of the users of the site will be located in Australia, and so am I and my client. Now, I want to consider everything before deciding on host and few questions comes to my mind: I cannot afford website being down, and all hosts say something like "99% uptime guranted". Should just that be enough or shall I ask hosts for some stats maybe? Does it make any difference if servers and whole hosting company is located in Australia or outside? I've been hosting few sites with JustHost.com on shared hosting (cheapest plan, servers in US I believe) and never seen any delays but could that be an issue? I would prefer Australian company so I can actually go to them and give them piece of my mind if something goes wrong, but US servers seem cheaper. Would share hosting do? Its ecommerce custom build php application, I know there are security issues with sessions etc on shared hosting. Will take precautions of course but could share hosting be an issue? Would dedicated be worthy option considering that my knowledge of server is very limited? I need to run php/mysql, with preferably unlimited bandwidth as with my experience I cannot tell what amount of traffic would be sufficient. Please let me know if I didn't provide you with enough information so you could answer my questions, will gladly explain further. In advance thanks for any answers :)

• Ping with explicit next-hop selection (aka Monitoring multiple default gateways)

  - by Michuelnik

  I have a linux (debian) router with two internet connections (A) and (B). (A) is preferred, (B) is fallback. I want to monitor the internet connection (and not only the availability of the gateways!) and change the default route appropriately. If (A) is not providing internet, switch to (B) If (A) is providing internet again, switch back to (A). Only problem I have is in case (2). My routing table points towards a working internet so I cannot easily detect whether internet is working over link (A) again. I am search for a ping or traceroute (or other diagnosis-tool) which can select the next-hop explicitly. ping -r looks promising, but can only ping a host on the lan. (It only has to write another destination address in the packet, damnit!) traceroute -g gateway looks even more promising and nearly does what I want - but sets source routing options which my next-hops deny. (Not within my administrative boundary...) I just want a $ping, that can: select a source interface (and address) select a next-hop on that interface ping any arbitrary ip address I could do evil trickery with policy-based routing but that would have production impact for all users. I would like to see a side-effect-free solution....

• "Error 53" with local LAN machines after VPN session on server

  - by tim11g

  I have a Windows 2000 server with a Windows 7 client that occasionally gets "error 53" when accessing the server by name (net view \\server). It still works by IP address (net view \\192.168.0.1). The server's primary IP address (as shown in "routing and remote access" as "Gigabit Ethernet" is 192.168.0.1. There is also a secondary IP address shown as "Internal" which is 192.168.0.50 The server also supports VPN. When a VPN user connects, it gets an address in the range of 192.168.0.51 to .59. Normally (when there is no error), when the local LAN client runs "ping server", it resolves to 192.168.0.1. When the Error 53 problem happens, "ping server" resolves to 192.168.0.50. This problem seems to be related to when a user connects or has recently connected to the server VPN. Is there some connection between the VPN services on the server and the DNS services on the server that could cause a local LAN client to become confused about which IP address to use for the server? Or is there a misconfiguration in the VPN or DNS?

• Apache Named Virtual Hosts and HTTPS

  - by Freddie Witherden

  I have an SSL certificate which is valid for multiple (sub-) domains. In Apache I have configured this as follows: In /etc/apache2/apache2.conf NameVirtualHost <my ip>:443 Then for one named virtual host I have <VirtualHost <my ip>:443> ServerName ... SSLEngine on SSLCertificateFile ... SSLCertificateKeyFile ... SSLCertificateChainFile ... SSLCACertificateFile ... </VirtualHost> Finally, for every other site I want to be accessible over HTTPS I just have a <VirtualHost <my ip>:443> ServerName ... </VirtualHost> The good news is that it works. However, when I start Apache I get warning messages [warn] Init: SSL server IP/port conflict: Domain A:443 (...) vs. Domain B:443 (...) [warn] Init: SSL server IP/port conflict: Domain C:443 (...) vs. Domain B:443 (...) [warn] Init: You should not use name-based virtual hosts in conjunction with SSL!! So, my question is: how should I be configuring this? Clearly from the warning messages I am doing something wrong (although it does work!), however, the above configuration was the only one I could get to work. It is somewhat annoying as the configuration files have an explicit dependence on my IP address.

• How do I change the default ftp folder in MacOS X 10.6?

  - by Wild_Eep

  I'm running WordPress 2.9.1 from a Mac running 10.6.3. WordPress is installed to the /Library/WebServer/Documents folder. WordPress has a feature called AutoUpdate. Clicking an autoupdate button will download and install updated versions of the WordPress software, or third-party plugin tools. It's a convenient way to keep things up to date. WordPress uses FTP to download the files. I've enabled FTP and set up a user account and opened the requisite ports in my firewall for FTP traffic. This doesn't seem to be enough for my self-hosted installation, though. I'm sure this feature was originally designed for someone who has access to a remote shared webserver, and that it's merely a configuration challenge related to the FTP setup. I feel that if I can adjust the initial directory that the FTP service presents to the AutoUpdate feature, everything else will work properly. So, my question is, how do I adjust what folder is presented when a given user connects to a Mac running 10.6.3 via FTP?

• Gigabyte H55N-USB3: No video on HDMI

  - by newt

  I built a new PC with a Gigabyte H55N-USB3 / Intel Core i5 650. With a monitor plugged in the DVI port, everything works fine. I installed Windows 7 32-bit and enabled remote desktop connection. After that, I unplugged the monitor, plugged it into network and installed everything else (drivers, programs, etc) via RDP. However, when I try to use the HDMI port on my TV nothing appears. Neither during the boot, neither after Windows starts. The TV says there's "no signal" (if I remove the cable the message changes to "check cable"). The cable is new, and it is working fine with my home theater on same TV (by the way, it is the cable which came bundled with the home theater). Video driver is the latest from Intel site. Anyway, this shouldn't be the problem since there is no image during the boot. Any ideas or tips would be welcome. I'm googling around but found nothing useful, yet.

• GIT Website Deployment

  - by Brian

  I am attempting to setup GIT to deploy my project to different locations based on the branch. (I think this is what I want to do anyway). My current setup is this: Local dev machine running Netbeans to make changes. Remote server hosting GIT projects (same server running apache) - 2 subsites exist a test.FQDN.com and a live.FQDN.com What I would like to do is have 1 GIT project (MyProject) and create a new feature branch. Any commits done to the new feature branch would push to test.FQDN.com. Once the features have been tested and then merged into the master branch, it would push to live.FQDN.com. I have looked at GIT's post-receive hooks and was able to use "git checkout -f" command to pull on the test.FQDN.com site however that only pulls the master branch and not the new feature branch. I do not have any funding to use a third party to make this work, and would prefer to stay within GIT but have full root access to the web server if there is a package to install which would help control this. Any suggestions would be great!

• Application Pool Identity corruption

  - by Gavin Osborn

  I have observed a few times while deploying software into IIS that every now and again the related Application Pools fail to restart and in the Event Log we see an error like the following: The identity of application pool, 'AppPoolName' is invalid. If it remains invalid when the first request for the application pool is processed, the application pool will be disabled. This does not happen frequently but when it does the only solution is to re-apply the Identity password in the IIS Manager Window. As soon as I re-apply and then restart the application pool the web sites come back up. Facts: The account is a service account whose password never expires. The account is local to the IIS host. The account password is never changed. This is IIS 6 running on Windows Server 2003 Deployment of the software is via MSI and involves several IIS Resets. The software is created in house and does not do anything fancy to IIS. Any ideas how the identity information might become corrupt? Edit: Clarification To be clear - this user account and password combination work absolutely fine and usually works fine as the Identity of the Application Pool. It is only when we deploy updates of our software into an existing IIS application that it stops working. Our password has not changed Our deployment does not change the password or reconfigure the application pools. This does not happen every time, 1/20 times perhaps. If we re-enter the password into IIS and restart the App Pools everything works.

• Proper Outlook Free/Busy status when working from home

  - by rwmnau

  Our office (pretty large - about 200 people) has recently started part-time telecommuting. It's only one day/week now, but it's already raised some questions about availability, so I wanted to see how the users here, some of whom I'm sure telecommute to a corporate job, how they set their out of office status. Outlook has four statuses, and here's what I (and most others?) take them to mean: Free: I'm available for meetings Busy: I'm in a meeting or otherwise occupied, and unavailable Tentative: Shy away from scheduling over, but I'm available if needed Out of office: I'm on vacation and unavailable. However, I don't travel for work - do people tend to use this status to mean they're remote, but available for a phone call/bridge? As we begin to telecommute, I'll be available by phone for meetings, but not in person - any meeting can have a conference bridge, but some meetings just need to be in person. I'd like to send the right message about my status - people can schedule meetings with me on my telecommute days, but they should expect me to be on a conference bridge when they do. What status do people use? Does "Out of Office" correctly reflect that you're working from home, even though I perceive this to mean that somebody is on vacation? Maybe I'm the only one confused here, but as a company that's never before done telecommuting of any kind, I'm in the dark about standard practices. Thanks for the insight! Though this isn't a technical question directly, I'm hoping it's still applicable to the group and constructive - if it's not, please close it and accept my apology.

• IPTables forward from only one ip on my server

• CentOS 5.7 issues with iptables

  I'm trying to set up IPTables on a new CentOS server. This server will function as an FTP server that I need to be accessible from the outside, however, I want to lock down SSH to only accept internal IP connections. I need to allow SSH for 10.0.0.0/8 and 172.16.132.0/24. Below I've posted my /etc/sysconfig/iptables file.

• How to redirect a name-based VirtualHost to a different port?

  - by Andra

  I have a virtuoso sparql endpoint installed, which I want to make available through a hostname (e.g. www.virtuosoexample.com). The thing with virtuoso is that the is no Document root. The endpoint is initiated by the daemon and made available through a source port (e.g. localhost:1234/) I know how to set a virtual host pointing to a document root, but i don't know how to do this for a server with a port number. Any advice would be appreciated. Below is the code, how I would do it with a document root. I tried to change that (naively) into localhost:1234/sparql, but that didn't work <VirtualHost * ServerName www.virtuosoexample.com <www.virtuosoexample.com> ServerAlias www.virtuosoexample.com <www.virtuosoexample.com> ErrorLog /var/log/apache2/error.wp-sparql.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

• What can I do to determine the root cause of a Windows server hanging/freezing?

  - by Aaronaught

  We set up a new server here a few weeks ago that I am informally responsible for managing. Almost everything works perfectly except for one thing: Every so often it hangs without warning. To clarify: When I say hangs, I mean completely. None of the services respond and I'm unable to even get onto a local console - the display acts as though there's no VGA signal. One time, the server actually responded to pings, another time I got the "destination host unreachable" response, but most of the time the pings just time out, as one would expect for a hung server. Event logs don't show anything after a reboot. I don't mean that they don't show anything interesting, I mean that they don't show anything at all from before the failure occurs to after the reboot. And there are never any performance problems, strange errors, or other obvious signs of impending doom before it happens. I don't expect any easy answers here. What I'd like to know his I can methodically determine the root cause of this problem, be it a misbehaving service, defective hardware, or something else. Is there any kind of logging I can set up that will help me get to the bottom of this? Any hardware diagnostics or remote monitoring? Anything else I can do to help me discover what's actually happening, or at least be able to eliminate what isn't wrong? Just to reiterate, I really don't want to start speculating about possible causes and take a trial-and-error approach, because it's going to be at least several days at a time before I would have conclusive results. I'm looking for solutions to reliably trace the problem to its source.

• What could be wrong with my VLAN?

  - by Matt

  I've got a VLAN 10 setup as a management VLAN. The management VLAN comes off port 48 and links to another set of switches that do not support VLAN's so it was I believe set up as an untagged access port. In the past this was a different brand of switch and this worked fine. However, since changing to the HP V1910-48G series I can't seem to get this working. I must point out that as far as I'm aware it is wired up properly (I can't check this physically as I'm working remote and have asked the tech who's got access to double check for me). Now I don't have a huge amount of experience with VLAN environments but AFAIK this is right. I've set the port 48 (linked to the management switches) as an untagged port with PVID 10 and access link type. Is this all I'd need to do from a configuration perspective to ensure all devices connected to port 48 would end up being on VLAN 10 and not needing to tag their frames. i.e. the tag would be added by the switch before being forwarded.

• Pushing Windows Store apps silently

  - by seagull

  As part of a requirement I have been issued, I seek the ability to push apps from the Windows Store (.appx) to remote users. The framework surrounding the data transmission is sorted; What I need to know is if there is a script that can be sent out along with a URI or the package proper to facilitate installation on the user-side of the Windows Store app. I am well aware that numerous guides exist from Microsoft on pushing out Line-of-Business (LOB) (AKA Enterprise) applications -- that is, apps that have been developed in-house and are not for the consumption of the Windows store. This is inappropriate for my requirement, however; the customer wants their clients to receive apps that appear currently on the Windows Store, and for them to be installed in a silent manner. I've seen this guide; http://blogs.technet.com/b/keithmayer/archive/2013/02/25/step-by-step-deploying-windows-8-apps-with-system-center-2012-service-pack-1.aspx, which details doing exactly this, but it is only applicable to machines that are administered by a system running Windows Server 2012 R2 with the 'System Center 2012' bundle installed. The systems I target are considerably more decentralised than this, making this guide inappropriate. I have a hunch that Microsoft have deliberately designed the Windows Store to be this way, but I figured I ought to ask around before I resign myself to the requirement. Much obliged

• Subdomain is preventing my search results from rising as expected in page rank

  - by culov

  My problem is that I have a site which has requires a dedicated page for every city I choose to support. Early on, I decided to use subdomains rather than a directly after my domain (ie i used la.truxmap.com rather than truxmap.com/la). I realize now that this was a major mistake because Google seems to treat la.truxmap.com as a completely different site as ny.truxmap.com. So for instance, if i search "la food truck map" my site will be near the top, however, if i search "nyc food truck map" im no where in sight because ny.truxmap.com wouldnt be very high in the page rank by itself, and it doesnt have the boost that it ought to be getting from the better known la.truxmap.com So a mistake I made a year ago is now haunting my page rank. I'd like to know what the most painless way of resolving my dilemma might be. I have received so much press at la.truxmap.com that I can't just kill the site, but could I re-direct all requests at la.truxmap.com to truxmap.com/la and do the same for all cities supported without trashing my current, satisfactory page rank results I'm getting from la.truxmap.com ?? EDIT I left out some critical information. I am using Google Apps to manage my domain (that is, to add the subdomains) and Google App Engine to host my site. Thus, Google Apps provides a simple mechanism to mask truxmap.appspot.com (the app engine domain) as la.truxmap.com, but I don't see how I can mask it as truxmap.com/la. If I can get this done, then I can just 301 redirect la.truxmap.com to truxmap.com/la as suggested below. Thanks so much!

• How to display/define Mirror/Stripping pairs with mdadm

  - by Chris

  I want to make a standard linux software Raid10 over 4 HDD. The server has 4HDDs, 2 pairs from different vendors in order to avoid batch problems. I want to have the mirror over two different Vendors, and then the Stripe over the mirror pairs. I could do that by manually creating Raid1/0, but mdadm supports Raid level 10. I just cant figure out how the Raid10 is then handled and how the data is distributed. mdadm --detail /dev/md10 /dev/md10: Version : 1.2 Creation Time : Wed May 28 11:06:23 2014 Raid Level : raid10 Array Size : 1953260544 (1862.77 GiB 2000.14 GB) Used Dev Size : 976630272 (931.39 GiB 1000.07 GB) Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Update Time : Wed May 28 11:06:23 2014 State : clean, resyncing (PENDING) Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Layout : near=2 Chunk Size : 512K Name : pdwhost:10 (local to host pdwhost) UUID : a3de0ad5:9e694ee1:addc6786:c4449e40 Events : 0 Number Major Minor RaidDevice State 0 8 1 0 active sync /dev/sda1 1 8 81 1 active sync /dev/sdf1 2 8 97 2 active sync /dev/sdg1 3 8 113 3 active sync /dev/sdh1 does not really give any information about that. How it should be: Raid 1 / Mirror over /dev/sda1 /dev/sdf1 and /dev/sdg1 /dev/sdh1 Raid 0 over the two Raid 1 pairs Is it possible to do that with the built in "level=10", how can I see what pairs are mirrored? Thanks a lot for you help

• Best method to redirect internal DNS to external website?

  - by ProfessionalAmateur

  We host several web based applications outside of intranet. The URL's to these applications are long, complex and overall not user friendly. Ex: http://hostingsite:port/approot/folder/folder/login.aspx <-- (production) http://hostingsite:port22/approot/folder/folder/login.aspx <-- (dev) http://hostingsite:port33/approot/folder/folder/login.aspx <-- (test) I'd like to create an internal DNS entry to allow users to access these sites with ease. Ex: http://prod --> http://hostingsite:port/approot/folder/folder/login.aspx http://dev --> http://hostingsite:port22/approot/folder/folder/login.aspx I'm not familiar with the DNS process and setup, as far as I know a DNS can only be redirected to an IP, but not to subdomains for directory paths as described above? Is this a correct assumption? I am thinking for throwing up an internal webserver that will listen to the internal DNS entries and redirect to the external sites. http://prod --> [internal webserver] --> redirect --> http://hostingsite:port/approot/folder/folder/login.aspx Is there a better way to do this?

• Measure Upload Speed between a client and our server

  - by tresstylez

  We host a SAAS application specially customized for multiple clients. For one customer in particular -- they are reporting sporadic performance issues from various locations on their network, in particular UPLOADING documents through a form on our website. The client claims they have "bandwidth to spare" and that utilization of their "pipe" is so low that it MUST be our application, but our application has MANY clients and all features are working fine for all other clients. Interestingly enough -- DOWNLOADS (ie. just accessing the website, or downloading documents) is working fine. Speed test shows that they should get 1.2Mbps UP. So, a 3MB file should take 20 secs to upload. It takes 60+ seconds on their network. Sometimes even small files take OVER 10 minutes to upload or they timeout. Pings and Traceroutes don't show any abnormally long hops or response times. They claim other SAAS applications they use allow them to upload just fine. Both IT teams are working together to resolve this issue. What kind of data can I request from the clients to begin ruling things out. Seems like we need to somehow measure LATENCY of the networks involved or even at the switch level, we need to understand if packets are getting dropped somewhere and why. Where should I start? Any help is appreciated. I'll provide more info upon requests

• .htaccess issue on Apache Web Server in Ubuntu VM

  - by Neon Flash

  I just installed Apache Web Server on Ubuntu 11.04 in VMWare Workstation. I created a basic HTML page, named it index.html and placed it in /var/www directory (document root). I am able to access this web page from my Host OS (Windows 7), by pointing the browser to: http://192.168.2.2/index.html where, 192.168.2.2 is the IP Address of the Ubuntu VM. Next, to test various configurations of .htaccess files, I created a new directory in /var/www called, members. Inside this directory, I created and placed a .htaccess file with the following configuration: AuthUserFile /www/Neon/auth/.htpasswd AuthName "neon's home" AuthType Basic require valid-user IndexIgnore */* I created a directory path like /var/www/Neon/auth/ and then placed a .htpasswd file inside it. To place the username and hash inside the .htpasswd file: I created a username "neon" and calculated the DES hash of a password and placed it inside .htpasswd file in format: username:hash Now, when I try to access the web page: http://192.168.2.2/members/ It does not prompt me to enter the username and password with a popup box. Instead it just displays the index.html which is placed inside members directory. I would like to get this configuration working :)
