• Office documents on intranet all requiring second login and can't pass auth? Disable webdav?

  - by DOTang

  I am not sure what is going on, but recently all the Office documents on our intranet get prompted a second time for login and according to the error logs it looks like it's trying to use webdav to open (an editable?) version of the document to save directly on the server? We have no sharepoint server setup or anything, but this shouldn't be happening. All I want is for the document to be saved or opened from a local copy in temp like normal. Here is the log: Line 57499: 2011-04-12 15:57:10 (ip) OPTIONS (address) - 443 (username) (user ip) Microsoft-WebDAV-MiniRedir/6.1.7601 - 401 1 1326 1525 238 0 Line 57500: 2011-04-12 15:57:10 (ip) OPTIONS (address) - 443 (username) (user ip) Microsoft-WebDAV-MiniRedir/6.1.7601 - 401 1 1326 1525 238 0 Line 57501: 2011-04-12 15:57:10 (ip) OPTIONS (address) - 443 (username) (user ip) Microsoft-WebDAV-MiniRedir/6.1.7601 - 401 1 1326 1525 238 0 The log basically contains a bunch of these. How can I disable this behavior so that office documents that are downloaded aren't attempted to be used through webdav?? Edit: I should clarify behavior, it asks if you want to save or open it, upon choosing open open, it asks to re-authenicate, you put in the user information and the login box comes up 3 times acting like you entered the wrong password. For some users, after passing the login box the third time, it still opens up, for others their browser just locks up. It also doesn't even look like webdav is installed on our server, I see no config options in IIS for it as outlined on this page: http://learn.iis.net/page.aspx/350/installing-and-configuring-webdav-on-iis-7/#001

• Some of my keys are automatically being pressed along with other keys

  - by Santosh

  History The last time when my computer shutdown was a power failure. Now some keys are automatically being pressed when I type something. The last thing I did to keyboard setting was adding a keyboard layout (on Ubuntu). What is happening Whenever I press c, xc is writeen s gives me sd d gives me sd e gives me we 2 gives me 23, So when I want @ it gives me @# 3 gives me 23 Pressing CAPS Lock gives me F3 and vice-versa. All other key are either working fine or I don't use them. I have two operating system Ubuntu and Windows, I use Windows very less and found this problem on Ubuntu, but as soon as I logged in to Windows (for checking) then I found that Windows has the same problem. Effects on my life This starts form the time of login, even I have problem in typing my password. Whenever I try to save any webpage, it is bookmarked automatically. Whenever I copy, it is cut automatically. I have to spend more than half of time correcting what I have typed. Note: Typing thisd quwesdtion wasd rweally a big pain to mwe.

• tftpd starts randomly

  - by Mutant

  A few days ago my Little Snitch filter starts popping up tftpd. I'd never seen this before, so I immediately start freaking out thinking my Mac has been compromised. I can't find anything unusual on the system. The process usually dies before I can trace it (little snitch never allowed the connection just left the popup up). I finally caught it once, and found this: [10:32]: sudo lsof -nlP | fgrep tftp Password: tftpd 1924 18446744 cwd DIR 1,3 1326 2 / tftpd 1924 18446744 txt REG 1,3 29856 163979456 /usr/libexec/tftpd tftpd 1924 18446744 txt REG 1,3 600576 163686622 /usr/lib/dyld tftpd 1924 18446744 txt REG 1,3 303300608 189014898 /private/var/db/dyld/dyld_shared_cache_x86_64 tftpd 1924 18446744 0u IPv4 0x34a76100fcbb06e3 0t0 UDP *:55818 tftpd 1924 18446744 2u IPv4 0x34a76100f1113c53 0t0 UDP *:69 [10:32]: ps ax | fgrep 1924 1924 ??

Nothing in cron, launchdaemons, etc. Google searches haven't yielded much either. The connection IP is different each time. So my question is: Has anyone seen anything like this before?

• Strange File-Server I/O Spikes - What Is Causing This?

  - by CruftRemover

  I am currently having a problem with a small Linux server that is providing file-sharing services to four Windows 7 32-bit clients. The server is an AMD PhenomX3 with two Western Digital 10EADS (1TB) drives, attached to a Gigabyte GA-MA770T-UD3 mainboard and running Ubuntu Server 10.04.1 LTS. The client machines are taking an extremely long time to access/transfer data on the file server. Applications often become non-responsive while trying to open files located remotely, or one program attempting to open a file but having to wait will prevent other software from accessing network resources at all. Other examples include one image taking 20 seconds or more to open, and in one instance a user waited 110 seconds for Microsoft Word 2007 to save a document. I had initially thought the problem was network-related, but this appears not to be the case. All cables and switches have been tested (one cable was replaced) for verification. This was additionally confirmed when closing down all client machines and rebooting the server resulted in the hard-drive light staying on solid during the startup process. For the first 15 minutes during boot, logon and after logging on (with no client machines attached), the system displayed a load average of 4 or higher. Symptoms included waiting several minutes for the logon prompt to appear, and then several minutes for the password prompt to appear after typing in a user name. After logon, it also took upwards of 45 seconds for the 'smartctl' man page to appear after the command 'man smartctl' was issued. After 15 minutes of this behaviour, the load average dropped to around 0.02 and the machine behaved normally. I have also considered that the problem is hard-drive-related, however diagnostic programs reveal no drive problems. Western Digital DLG, Spinrite and SMARTUDM show no abnormal characteristics - the drives are in perfect health as far as the hardware is concerned. I have thus far been completely unable to track down the cause of this problem, so any help is greatly appreciated. Requested Information: Output of 'free' hxxp://pastebin.com/mfsJS8HS (stupid spam filter) The command 'hdparm -d /dev/sda1' reports: HDIO_GET_DMA failed: Inappropriate ioctl for device (the BIOS is set to AHCI - I probably should have mentioned that).

• Is there any way to synchronize AD users with Office 365 but still be able to edit them online?

  - by Massimo

  I'm performing a migration to Office 365 from a third-party mail server (MDaemon); the local Active Directory doesn't include any Exchange server, and never had any. We will need directory synchronization in order to enable users to log on to Office 365 using their domain credentials; but it seems that as soon as you enable directory synchronization, you can't perform any action anymore on Office 365 users: all changes need to be made on the local Active Directory, and then replicated by the synchronization process. For ordinary users with a single e-mail address and standard features, this is not a big problem; but what about users which need an additional address? What if I need to configure some nonstandard setting, like "hide from address list" or a custom mailbox quota? From what I've gathered, the only supported way to do this, as you can't directly edit Office 365 objects anymore after synchronization is enabled, is to extend the local AD schema with Exchange attributes, and then manually edit them (!). Or, you can install at least one local Exchange server, and then use the Exchange administrative tools to configure the required settings. Is this correct or am I missing something? Is there any way to synchronize user accounts and password, but still be able to edit user settings directly in Office 365? If not (everything really needs to be set locally and then synchronized), is there any simpler way to do this than manually editing LDAP attributes or installing a local Exchange server?

• Is it possible to trace someone using Google during an online exam?

  - by George

  I happen to be a professor at a reputed college. I want to design an online exam for over 1000 students via around 50 computers right after the vacation ends. Now the problem is that I have heard that many students use Google on a different tab to find answers when no invigilator is around. I want to know if there is a way to backtrace it after the exams via some kind of history or any other possible way. In our university there is a standard system. I am not good with computers but I will try to explain. Each computer uses mozilla to connect to a server centrally located via an IP. The students open it and enter a unique ID and password to start the exams. Many questions are jumbled and different groups of students give exam in a different time slot. Is there any way to trace it since I want to set an example for students so they won't cheat and give exams in an honest way. Additional details: Since the number of computers are less than the number of students, more than 10 students are going to use a single computer on a single day over a period of 10 hours. After this, if I check the history (and let's say someone even forgot to delete the history and I see it), will I able to figure out who among the 10 has done it? Moreover, is it even practical and feasible?

• Certificates in SQL Server 2008

  - by Brandi

  I need to implement SSL for transmissions between my application and Sql Server 2008. I am using Windows 7, Sql Server 2008, Sql Server Management Studio, and my application is written in c#. I was trying to follow the MSDN page on creating certificates and this under 'Encrpyt for a specific client', but I got hopelessly confused. I need some baby steps to get further down the road to implementing encryption successfully. First, I don't understand MMC. I see a lot of certificates in there... are these certificates that I should be using for my own encryption or are these being used for things that already exist? Another thing, I assume all these certificates are files are located on my local computer, so why is there a folder called 'Personal'? Second, to avoid the above issue, I did a little experiment with a self-signed assembly. As shown in the MSDN link above, I used SQL executed in SSMS to create a self-signed certificate. Then I used the following connection string to connect: Data Source=myServer;Initial Catalog=myDatabase;User ID=myUser;Password=myPassword;Encrypt=True;TrustServerCertificate=True It connected, worked. Then I deleted the certificate I'd just created and it still worked. Obviously it was never doing anything, but why not? How would I tell if it's actually "working"? I think I may be missing an intermediate step of (somehow?) getting the file off of SSMS and onto the client? I don't know what I'm doing in the least bit, so any help, advice, comments, references you can give me are much appreciated. Thank you in advance. :)

• Windows 8 preinstall downgrade to Win 7: UEFI problems :/

  - by Tim Flemming

  I have a friend who has a Hp Laptop with UEFI booting. He locked himself out of windows 8 (forgot his password)... so he called me. Well after trying to use the latest version of chntpw in UBCD5.2.6, i came to the conclusion i needed to wipe the drive and install windows 7. A little googling suggested using certain versions of chntpw, but i decided to not waste the time burning endless CDs. Anyway, He agreed to installing Win7 "I hate the big tile thingys". So i attacked with Gparted. Wiped the whole drive. Set flags to boot. Set part table as MBR. However upon trying to install win7, it still claimed i had a GPT style disk. unable to install. the only thing i can think of I'm doing wrong is not changing the bios/UEFI to legacy... My question is, If I enable legacy, somehow get the drive to actually be MBR, and use my X86 DVD, should I be good? Is there some common glitches ppl miss when dealing with GPT/EFI/UEFI? I need answers cuz he now has a blank laptop which I am responsible for. Another question. windows 8 came installed on a GPT disk. SO WHY WHEN I BOOT THE INSTALL DVD DOES IT SAY IT CANT INSTALL TO A GPT STYLE DISK??? WTF??? talk about the bleeding edge man.

• Powershell Script Scheduled Task Stopped Running (Could not Start)

  - by Hatsune Yuki

  I'm running a scheduled task (for Powershell Script) on Windows 2003 Server. I believe the script works fine. The task is scheduled to run every 10 minutes from 7:00am to 11:50pm everyday. However, it never gets to run more for than a day. It always stops some time in the afternoon (between 2pm and 6pm). I'm not sure exactly what happened but I always get the error The attempt to log on to the account associated with the task failed, therefore, the task did not run. The specific error is: 0x80070569: Logon failure: the user has not been granted the requested logon type at this computer. Verify that the task's Run-as name and password are valid and try again. It seems like most people with this error are saying that they need to make user "logon as a batch job". However, this option is greyed-out for me. I search for other places where users have similar problems but the solutions are not written in detail (some of them have something to do with GPO). I've only used the basic features of Windows Server and I have no clue how to get to the place they are referring to. Can someone please confirm whether "logon as a batch job" is indeed a solution and provide a detailed walkthrough on how to solve my problem? Thanks. p.s. someone suggested the website http://technet.microsoft.com/en-us/library/cc755659(v=ws.10) I tried to followed the method for web server with domain. However, got stuck on the 6th step where it mentions Group Policy Object. I don't know where it is.

• Can't remote into Virtual PC

  - by Spamela

  I used to be able to remote into my Virtual PCs. It has been working for at least a year. Yesterday just stopped working... I cannot figure it out... Things I have triple-checked: 1. My Virtual PCs have "Allow Remote Access" checked. 2. My Virtual PCs have an account in the Administrator group that is password protected. 3. My Host's entry in the registry for the Terminal Services Port is still the default of 3389. So here is the strange thing. I can't even remote into the Virtual PC from it's host much less another PC... From the host, I can ping the Virtual PC and get a response but when trying to remote into it from the host I get the following error: Remote Desktop can't connect to the remote computer for one of these reasons: 1)Remote access to the server is not enabled. 2)The remote computer is turned off 3)The remote computer is not available on the network My host is running Windows 7. Virtual PCs are running XP. Thank you for looking at this!

• Hyper-v and sql server connections for web apps

  - by Rick Ratayczak

  I have a physical machine running win8, and two VMs in hyper-v client: 1 web server, 1 sql server. The web server works fantastic. The sql is the one that is giving me the problem. I can connect to it with server explorer in visual studio or management studio just fine, and it's blazing fast. The problem happens when I use the same connection string I am using in visual studio server explorer in the web.config for an app. data source=VMSQL1;initial catalog=OtherShell;persist security info=True;user id=OtherShell;password=****;network library=dbmssocn;MultipleActiveResultSets=True;App=EntityFramework I made sure it was also using tcp-ip, but it doesn't connect with or without the network library part of the connection string. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) This is driving my batty for the last two days, any ideas? It fails from the web vm too, but works in management studio with the same connection string.

• Mounting fuse sshfs fails when invoked by Cron on FreeBSD 9.0

  - by Tal

  I have a remote server filesystem that I'm attempting to mount locally on a FreeBSD 9 machine via FUSE sshfs, and Cron for a backup routine. I have ssh keys between the boxes setup to allow for passwordless login as the root user on the local machine. Cron is set to run the following script (in Root's crontab): #!/bin/sh echo "Mounting Share" /usr/local/bin/sshfs -C -o reconnect -o idmap=user -o workaround=all <remote user>@<remote domain>.com: /mnt/remote_server As root, I can run this script on the command line without issue, and without being asked for a password the share mounts successfully. Yet, when run by Cron the script fails. The path to sshfs is identical to the value of which sshfs Here is the email root receives from the Cron Daemon: X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <HOME=/root> X-Cron-Env: <PATH=/usr/bin:/bin> X-Cron-Env: <LOGNAME=root> X-Cron-Env: <USER=root> Mounting Share fuse: failed to exec mount program: No such file or directory fuse: failed to mount file system: No such file or directory I'm stumped as to why I'm receiving No such file or directory in this instance. It further seems odd given that the paths appear to be correct. I've also attempted to compare the output of env on the shell with env inserted into the script. I don't see any environment variables that should cause this trouble. At bootup, FUSE reports its version as: fuse4bsd: version 0.3.9-pre1, FUSE ABI 7.8 Help me ServerFault wizards, you're my only hope!

• How do I automatically connect my client to an ODBC data source on another machine with dynamic IP?

  - by Kdansky

  At the customer's place, we've got a postgres DB on a server, and a few clients. We connect them through ODBC-drivers, and all machines run windows (usually XP). Now we had a few annoying issues: The client "forgets" some flags in the ODBC drivers, such as ByteA as LO. Every time anything changes, we have to reset that, and type in the password, and sometimes even the IP of the server. On x64 machines running Windows 7, configuring this is a pain as the system settings dialogue will only show 64-bit connections by default. And most importantly: If the server changes IP because the customer restarts or replaces a switch, all connections are lost. Annoyingly, this cannot be fixed with just correcting the IP, but rather, we have to check every single place (even hba_conf) because all the settings magically disappear. Our customers often are very small companies, where "server" means "that one PC in the other room", and not "Oracle mainframe in the dungeon", so we don't want to rely on them not restarting switches. Is there a better way than to rely on these really unstable settings? Are these settings somewhere in a file which I could edit manually, to make fixing it easier?

• Compatibility of Fedora install on a Hybrid drive

  - by kjh

  I recently bought un ultrabook with a 500gb/32gb sdd hdd hybrid drive, and I'm having trouble replacing windows on it with fedora seventeen. it errors out saying there was an unhandled exception. Is linux compatible with hybrid drives? or can the operating system on a hybrid drive not be replaced? Edit: here are the steps I select special storage devices because it ignores my hard drives otherwise at this point i get the message: "Disk contains bios raid meta data, disk sda will be ignored" I can pick a hostname, select my timezone and set a password at the install type screen, no matter what I select (use all free space, replace linux systems, create custom partition etc..) once I click next, it says "an unhandled exception" has occured. and I can no longer proceed with installation. Here is the error message: anaconda 17.29 exception report Traceback (most recent call first); File "/usr/lib64/python2.7/size-packages/pyanaconda/bootloader.py"; line 183 self.stage1_drive=self_drives[0] File "/usr/lib64/python2.7/site-packages/pyanaconda/rw/cleardisks_gui.ph"; line... and tons of more lines like that

• How do I prevent my computer from freezing when it starts to swap?

  - by cdauth

  I work as a Java programmer, so I often have to run several programs at the same time that consume a lot of memory. When my memory is full and Linux starts swapping, my computer almost completely freezes. I can see that it is heavily writing on the hard-disk and everything reacts really slowly, often not at all. Moving the mouse in X sometimes doesn’t work at all, sometimes it has a delay of several seconds, clicking usually has a delay of several minutes. Sometimes it is possible to change to the TTY (with a long delay), there I can usually type without delay, but when I try to log in, it takes several minutes after typing in the user name until the password prompt appears, and usually an error message appears that tells me that the login timed out. So the only possibility is usually to restart the computer. I noticed that other intensive writing to the hard disk also significantly slows down my computer. Sometimes, I used rsync to limit the bandwidth when I copied files around on my own computer, as else the system would be almost unusable. How can this be? At the moment it seems more useful to me to completely turn off swapping. That might crash some processes, which is unfortunate, but the alternative at the moment is to crash all processes by turning off my computer. I am using Gentoo Linux with kernel 3.6.2-gentoo, I have a 10 GB swap partition on a HDD.

• ssh hangs on "Last login" line

  - by Pavel H

  This happened for the first time three days ago - I ssh to the server, authenticate using a password, get the welcome message but it remains hanging on the "Last login:..." line. The command line doesn't show and the server doesn't react to my input. Other services on the server keep working ok (apache, tomcat, database, ..). The box has an out-of-band management using which I was able to restart it. After the restart the ssh worked ok again and I didn't find anything suspicious in the logs. Three days later the same problem occurs on this box again, and newly on yet another server in the cluster - 100% same symptoms. Both servers have about 2 month old installation of Debian Squeeze (6.0.2) and the problem never occurred before despite frequent ssh-ing, so it should not be a problem of settings. We haven't been installing anything new for quite some time now. I also made sure there is enough disk space on both servers. Since it started to happen all of a sudden on two servers at about the same time, I suspect some bug may have been introduced via Debian updates, yet I haven't been able to find anyone with the same problem. Most similar issues I have found: ssh freezes at the "Last Login Line" - in our case everything worked fine until recently, so nothing related to settings should be our problem. Diskspace checked, I couldn't check the memory but I would expect something would be in the logs if the system had been running out of it. Remote Fedora system unresponsive, odd but consistent behavior when trying to log in - problem with high load on the server; unlike in this case, nothing changes even if I wait for 10+ minutes

• How to deal with ssh's "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!"?

  - by Vi.

  I often need to login to multiple remote stations that are just placed to the same static IPs for me. SSH complains about changed keys in this case: $ ssh [email protected] @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ ...

• Kickstarting an Ubuntu Server 10.04 installation (DHCP fails)

  - by William

  I'm trying to automate the network installation of Ubuntu 10.04 LTS with an anaconda kickstart and everything seems to running except for the initial DHCP autoconfiguration. The installer attempts to configure the install via DHCP but fails on its first attempt. This brings me to a prompt where I can retry DHCP and it seems to always work on the second attempt. My issue is that this is not really automated if I have to hit retry for DHCP. Is there something I can add to the kickstart file so that it will automatically retry or better yet not fail the first time? Thanks.

• UIDs for service users in Mac OS X

  - by LaC

  Some third-party servers should be run under a special user for security reasons (eg, PostgreSQL is typically run by "postgres"). Of course, these service users should not show up in the Mac OS X login windows. I know how to create hidden users using dscl or dsimport, but I'm wondering what the best policy is for assigning UIDs (and matching GIDs). Apple's documentation states that UIDs from 0 to 100 are reserved (pg. 69), but OS X comes with several special users and groups outside that range. I used to use ids from 401 onwards for services, but I noticed that OS X 10.6 has started using that range for groups created by the Sharing pane in System Preferences. What is the recommended ID range to use for third-party services, then? Perhaps I should just use IDs in the 500 range, since all that is needed to hide a user in Snow Leopard is setting his password to "*"? Also, most of Apple's services have names starting with an underscore, with an alias sans underscore; eg, _sandbox and sandbox. Is there any special significance to this? Should I do the same for my services?

From an administrator account (called admin) within the VM, I try to access the hidden C$ share on machine0 (i.e. start - run - "\\machine0\C$\"). I get no prompts for credentials. Worse, machine0 has an admin account (different password), and machine0\admin gets locked out when VM\admin tries to access the network share. I get a message several seconds later, which feels like a cached credential failure leading to the lockout. I have checked several places for cached credentials; net use, Stored Usernames and Passwords, mapped shares. I rebooted (both machine0 and VM) to make sure the session was clear of any cached credentials. I can force net use to use my domain credentials when accessing machine0, and then I can see the share. I can also see shares that do not require credentials. I decided to try another machine on the network (machine1), 64-bit Vista, local user. This machine has no lockout policy, and after several seconds (feels like failed cached credentials again) it prompts me for credentials. After I enter them, it re-prompts me, saying "logon unsuccessful" (tried my domain credentials, and also machine1\admin's). Which is bogus, because I proceed to log on with remote desktop using the machine1\admin credentials. I have tried this on another machine (machine2, 64-bit Vista), running a copy of the same 32-bit VM, and I don't remember having this problem. machine0 has a fingerprint reader...could that try storing passwords and interfere? Are there any places I'm missing where there could be cached credentials? Is there a way to see what credentials are flying around when I try to connect?

• Getting dwl-g122 to work on ubuntu

  - by User1

  I have a USB WiFi adapter, D-Link dwl-g122. I'm running Ubuntu 10.4. My laptop has a built-in wireless card that is connecting fine to the router. I plug in the usb and it never really connects. Here are some details: iwconfig wlan1 IEEE 802.11bg ESSID:"\x0B\xE1..." Mode:Managed Frequency:2.457 GHz Access Point: Not-Associated Tx-Power=19 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:on lshw -c network: *-network:1 description: Wireless interface physical id: 3 logical name: wlan1 serial: 00:13:46:8b:xx:xx capabilities: ethernet physical wireless configuration: broadcast=yes multicast=yes wireless=IEEE 802.11bg dmesg [ 1096.814176] wlan1: direct probe to AP xxx (try 1) [ 1096.820960] wlan1: direct probe responded [ 1096.820969] wlan1: authenticate with AP xxx (try 1) [ 1096.823790] wlan1: authenticated [ 1096.823869] wlan1: associate with AP xxx (try 1) [ 1096.827667] wlan1: RX AssocResp from xxx (capab=0x411 status=0 aid=1) [ 1096.827674] wlan1: associated [ 1142.590912] wlan1: deauthenticating from xxx by local choice (reason=3) lsmod|rt2 rt2500usb 19643 0 rt2x00usb 11260 1 rt2500usb rt2x00lib 32133 2 rt2500usb,rt2x00usb mac80211 238896 3 ath5k,rt2x00usb,rt2x00lib cfg80211 148725 4 ath5k,ath,rt2x00lib,mac80211 led_class 3764 3 ath5k,rt2x00lib,sdhci It looks like the driver loads but it doesn't feel like connecting. The behavior is identical even if I blacklist the other wifi card (using an ath5k driver). It's almost like it is using the wrong password or something. Does anyone know what is happening? Is anyone using Ubuntu successful?

• can't register a soft phone to asterisk11

  - by Tom

  I have a VM (on oracle vbox) running Fedora17. I've installed asterisk 11 on it from sources. I've followed the wiki for installation (https://wiki.asterisk.org/wiki/display/AST/Creating+SIP+Accounts) to the letter. The ip on the VM machine running fedora is 192.168.1.7 and I can ping it from the host machine (Ubuntu 12.04), which is at 192.168.1.2 I've tried registering with ekiga with the following settings: user: [email protected]. Password: verysecretpassword registar: 192.168.1.7 but I'm getting an error "transport fail". Also, while trying to register I'm logged in to the asterisk CLI with verbose level 3 and debug level 4 and nothing appears. some more relevant data: I've added the following code to the end of my sip.conf.sample file: [demo-alice] type=friend host=dynamic secret=verysecretpassword context=users deny=0.0.0.0/0 permit=192.168.1.0/255.255.255.0 [demo-bob] type=friend host=dynamic secret=othersecretpassword context=users deny=0.0.0.0/0 permit=192.168.1.0/255.255.255.0 After I changed the sip.conf.sample file, I've created a copy of it and named it sip.conf. then I logged in to the asterisk CLI and typed sip reload. Then I'm trying to register and ekiga client from my host machine at 192.168.1.2 but it doesn't work and nothing appears on the asterisk CLI while in verbose mode level 3. BTW, If there is missing information about my question, please don't close it. comment about what you need to know and I'll edit it in to the question. tnx.

• REMOTE_USER not getting set?

  - by landed

  I am trying to setup LDAP Authentication in Joomla using a plugin called JMapMyLDAP (in fact 4 plugins each doing a different job). I need to pull a part of a string out of the server variable REMOTE_USER and this should be visible (we see here http://timplummer.com.au/4-how-to-integrate-joomla-3-with-active-directory-using-ldap.html) in phpinfo(); The issue is that REMOTE_USER is not set or at least not appearing. A few things to note (if you don't mind) here- conceptually I am not really understanding authentication as a whole subject it appears to be vast despite my years working in websites. Yes I used asp and built php pages to check a user is who they say they are with a token(/session?) that was given to just them and then they are identified when a stateless request is made to the server. Thats my level of understanding. This sounds different to the basic authentication in apache where a password sits in a file and a username and the user needs to login to a basic form to get access to the folder/docs this is via an .htaccess file. Ok so with the LDAP to work I need to get REMOTE_USER this sounds very reasonable as how else do we know is making the request. Thank you.

• Trouble setting up incoming VPN in Microsoft SBS 2008 through a Cisco ASA 5505 appliance

  - by Nils

  I have replaced an aging firewall (custom setup using Linux) with a Cisco ASA 5505 appliance for our network. It's a very simple setup with around 10 workstations and a single Small Business Server 2008. Setting up incoming ports for SMTP, HTTPS, remote desktop etc. to the SBS went fine - they are working like they should. However, I have not succeeded in allowing incoming VPN connections. The clients trying to connect (running Windows 7) are stuck with the "Verifying username and password..." dialog before getting an error message 30 seconds later. We have a single external, static IP, so I cannot set up the VPN connection on another IP address. I have forwarded TCP port 1723 the same way as I did for SMTP and the others, by adding a static NAT route translating traffic from the SBS server on port 1723 to the outside interface. In addition, I set up an access rule allowing all GRE packets (src any, dst any). I have figured that I must somehow forward incoming GRE packets to the SBS server, but this is where I am stuck. I am using ADSM to configure the 5505 (not console). Any help is very much appreciated!
