• pGina with automatic Kerberos ticket and OpenAFS token/ticket

  - by rolands

  I am currently updating our educational Windows lab images from XP to 7, In doing so we are also migrating from Comtarsia to pGina. Unfortunately somewhere in the transition our automation that fetched kerberos and OpenAFS tickets/tokens on login has completely stopped functioning. Basically what used to happen was, using kfw-3.2.2 and the old OpenAFS release (loopback adapter days), either comtarsia would share password or something with the NIM (Network Identity Manager) which would authenticate against the kerberos server gaining a ticket and AFS token needed to access the users file, this was aided by the fact that our ldap database that windows authenticates against is also what kerberos uses to authenticate so usernames/passwords are the same across both services. I have set up all of the tools, albeit newer 64bit versions which seem to have given me less trouble than the previous releases of NIM/OpenAFS/Krb5, as well as setting their configurations back to what we used to use. Unfortunately this seems to be fubar'd in some way, instead all we get now is a OpenAFS token, most likely I assume from the AFScreds tool which operates some kind of integrated login process, although this does not help in getting a kerberos ticket or a afs ticket for which a login box is provided be NIM after the user logs in. Does anyone know IF it is possible to do what we are trying, and if so how? I was considering writing a pGina plugin which would interact with the server itself but this seems slightly like overkill considering that all these applications already exist...

• Exclude specific domains from Apache2 serverAlias while using a catch all *(wildcard) alias

  - by Victor S

  I have a web application that needs to support custom domains, in that regard I have set-up the following name based virtual server: <VirtualHost *:80> ServerName example.com ServerAlias * *.example.com www.example.com example.com RailsEnv production RackEnv production DocumentRoot /srv/www/example/current/public <Directory /srv/www/example/current/public> AllowOverride all Options -MultiViews FollowSymLinks </Directory> ErrorLog /srv/www/example/log/error.log TransferLog /srv/www/example/log/access.log </VirtualHost> Notice the * as the server alias? that catches all the domains on that server. However, I have other sites on this server which I want to be excluded from this list. It is more economical for me to have a list of excluded domains than manually set every domain a user may register with at this service as a serverAlias... Perhaps this is not the best way to go, but I'm looking for help, in the best (relatively simple) way to set up a web-app that may catch any domains, while allowing other specific domains to be routed to different apps. Thanks!

• Telnet does not give a response

  - by floorish

  Some wireless access points are acting a little weird, so I want to reboot them every couple of hours. Luckily there exists a security flaw which lets me login as root through telnet when using port 1111 (without username and password). Now I want to use that to let my QNAP NAS execute the reboot command through telnet every now and then. The problem is however that that telnet version doesn't give any response if I connect to the AP. The telnet I use on OSX works just fine but the one on the NAS not. BusyBox v1.01 (2012.06.14-18:35+0000) multi-call binary Usage: telnet [-a] [-l USER] HOST [PORT] When I execute telnet <HOST> 1111 nothing happens. I can send the escape character ^] which gives me the following options: Console escape. Commands are: l go to line mode c go to character mode z suspend telnet e exit telnet The only way to get some commands executed is by suspending telnet with z followed by some random command which isn't recognized. Then the prompt shows this: # telnet 192.168.1.5 1111 ^] Console escape. Commands are: l go to line mode c go to character mode z suspend telnet e exit telnet z continuing... asdf Illegal command. 00> After that I am able to communicate with the AP, but when I exit the telnet session and try the same again, the AP refuses to connect at all and it must be manually rebooted (looks like the telnet session isn't shut down properly on the AP). So the question is what commands should I execute in order to communicate with the AP using the Busybox telnet version of the QNAP? (No, can't use ssh unfortunately)

• postfix + opendkim not signing correctly. how to debug this?

  - by Dean Hiller

  EDIT: I did get a little further but all posts on my search say permissions are wrong or regenerate key but I fixed that to be 644 as well as owned by DKIM AND I keep regenerating the key but it is not helping. My latest error now is this Apr 21 21:19:12 Sniffy opendkim[8729]: BB5BF3AA66: dkim_eom(): resource unavailable: d2i_PrivateKey_bio() failed Apr 21 21:19:12 Sniffy postfix/cleanup[8627]: BB5BF3AA66: milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]: 4.7.0 resource unavailable; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<abcs.com> I am looking for a way to simply debug this(don't necessarily need the answer but a way to get logs from opendkim would be good). If I stop opendkim, I see postfix log connection refused which is good. but when I send mail with opendkim started, I see no logs whatsoever. I even add the "LogWhy Yes" line to my opendkim.conf file as well and still see no logs there. Since I see opendkim running under user opendkim, I changed the owner of /etc/opendkim/* and /etc/opendkim and /etc/opendkim.conf all to opendkim user. I am running on ubuntu. My opendkim.conf file is # Log to syslog Syslog yes # Required to use local socket with MTAs that access the socket as a non- # privileged user (e.g. Postfix) UMask 002 # Sign for example.com with key in /etc/mail/dkim.key using # selector '2007' (e.g. 2007._domainkey.example.com) #Domain example.com Domain sniffyapp.com #KeyFile /etc/mail/dkim.key KeyFile /etc/opendkim/keys/sniffyapp.com/default.private #Selector 2007 Selector default # Commonly-used options; the commented-out versions show the defaults. #Canonicalization simple Mode sv #SubDomains no #ADSPDiscard no Socket inet:8891:localhost ExternalIgnoreList refile:/etc/opendkim/TrustedHosts InternalHosts refile:/etc/opendkim/TrustedHosts LogWhy Yes I of course have these lines added to main.cf in postgres smtpd_milters = inet:127.0.0.1:8891 non_smtpd_milters = $smtpd_milters milter_default_action = accept

• Ubuntu 9.10 RSA authentication: ssh fails, filezilla runs fine

  - by MariusPontmercy

  This is quite a mistery for me. I usually use passwordless RSA authentication to login into my remote *nix servers with ssh and sftp. Never had any problem until now. I cannot connect to an Ubuntu 9.10 machine: user@myclient$ ssh -i .ssh/Ganymede_key [email protected] [...] debug1: Host 'ganymede.server.com' is known and matches the RSA host key. debug1: Found key in /home/user/.ssh/known_hosts:14 debug2: bits set: 494/1024 debug1: ssh_rsa_verify: signature correct debug2: kex_derive_keys debug2: set_newkeys: mode 1 debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug2: set_newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug2: service_accept: ssh-userauth debug1: SSH2_MSG_SERVICE_ACCEPT received debug2: key: .ssh/Ganymede_key (0xb96a0ef8) debug2: key: .ssh/Ganymede_key ((nil)) debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Next authentication method: publickey debug1: Offering public key: .ssh/Ganymede_key debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Trying private key: .ssh/Ganymede_key debug1: read PEM private key done: type RSA debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password,keyboard-interactive debug2: we did not send a packet, disable method debug1: Next authentication method: keyboard-interactive debug2: userauth_kbdint debug2: we sent a keyboard-interactive packet, wait for reply debug2: input_userauth_info_req debug2: input_userauth_info_req: num_prompts 1 Then it falls back to password authentication. If I disable password authentication on the remote machine my connection attempt just fails with a "Permission denied (publickey)." state. Same thing for sftp from command line. The "funny" thing is that the exact same RSA key works like a charm with a Filezilla sftp session instead: 12:08:00 Trace: Offered public key from "/home/user/.filezilla/keys/Ganymede_key" 12:08:00 Trace: Offer of public key accepted, trying to authenticate using it. 12:08:01 Trace: Access granted 12:08:01 Trace: Opened channel for session 12:08:01 Trace: Started a shell/command 12:08:01 Status: Connected to ganymede.server.com 12:08:02 Trace: CSftpControlSocket::ConnectParseResponse() 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Status: Retrieving directory listing... 12:08:02 Trace: CSftpControlSocket::SendNextCommand() 12:08:02 Trace: CSftpControlSocket::ChangeDirSend() 12:08:02 Command: pwd 12:08:02 Response: Current directory is: "/root" 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Trace: CSftpControlSocket::ParseSubcommandResult(0) 12:08:02 Trace: CSftpControlSocket::ListSubcommandResult() 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Status: Directory listing successful Any thoughts?

• VMWare ESXi 4.1- 5.1 installation hang

  - by osij2is

  I'm well aware that I'm trying to install VMWare ESXi 5.1 on hardware that's not on the HCL. I can't find my motherboard on the ultimatewhitebox site as well. I acknowledge these issues in advance. What I'm trying to find is someway to access the logs during installation or see a console or log file to see where the installation is hanging at and remove a device or change a setting in the BIOS. The installation is hanging, not getting a purple screen of death. I thought by hitting ALT+F10 or F12 (or some key combination as such) would enable me to see the console but no such luck. I haven't been able to find much within the ESXi online documentation either. Here's the parts I'm using: AMD Phenom II x3 700 MSI 890FXA-GD70 (IOMMU capable) 16GB DDR3 1333 RAM (2x8GB DIMMs) Intel Pro 1000 (Dual-GbE) PCIe x4 (removed during installation) LSI 9211-8i PCIe (removed during installation) LSI 9201-16i PCIe (removed during installation) Matrox video card BIOS settings: IOMMU is enabled (during 5.1 IOMMU successfully loads) AHCI is enabled (hangs for 4.1) Both onboard Realtek NICs are disabled For ESXi 5.1, the installation hangs after vmkapi_v2_0_0_0 is loaded. For ESXi 5.0, it hangs when loading the vmklinux_9 module. For ESXi 4.1 U3, the installation hangs during loading of ahci module. Again, I'm looking for some way to view a console (service console?) or log file during or after an installation attempt to see what verbose error messages or logging can lead me to solving this problem.

• How to mount a LOFS in Solaris that doesn’t cross mountpoints

  - by jcea

  I need to access my "root" ZFS dataset to delete a file under "/var". But "/var" is overlayed by another ZFS dataset. Since these are system datasets I can't "umount" them while the machine is running. And I want to avoid to reboot the system in "failsafe" mode, since this is a production machine. Teorically ZFS would refuse to mount "/var" dataset over the underlying "/var", because it is not empty. But it works, possibly because they are system datasets mounted early in the boot process. But having the underlying "/var" not empty is preventing me to create an ABE (Alternate Boot Environment), so patching is risky, and I can't upgrade my system using Live Upgrade. The machine is remote. I have an IP KVM, but I rather prefer to avoid booting this machine in "failsafe" mode, if I can. I know there is a file in "/var/" because I can snapshot the "root" dataset and check it. But snapshots are read-only, so I can't get rid of the file. I tried "mkdir /tmp/zzz; mount -F lofs / /tmp/zzz", but when I go to "/tmp/zzz/var", I see the "/var" dataset, not the underlying "root" dataset. That is, the LOFS is crossing mountpoints. I would usually like it, but not this time!. Any suggestion, beside rebooting the machine in "failsafe" and mess with it thru the IP KVM?

• Commvault Oracle RMAN Restore to new host

  - by Glenn Stauffer

  We use Commvault Simpana 8 and I have a situation where I have backups of an Oracle database on tape that were taken from Host A. Host A suffered a disk failure (lost its raid configuration) and the sys admins are trying to restore it; in the meantime, I'd working to bring the database back up on another host - Host B. I'm running into problems and am trying to sort out the parameters that need to be passed to the Commvault media agent to get this to work. Unfortunately, I do not have access to Commvault support and the backup person is unavailable. Any one have a clue? The backups are there and the media agent reported a successful write when they ran last night. This is what fails: run { allocate channel t1 device type sbt_tape parms='SBT_LIBRARY=/usr/local/galaxy/Base/libobk.so,BLKSIZE=262144, ENV=(CvClientName=dbsrv2,CvInstanceName=Instance001, CVOraSID=BBPROD)'; restore spfile to pfile '/tmp/bbdb.ora' from autobackup; } allocated channel: t1 channel t1: sid=34 devtype=SBT_TAPE channel t1: CommVault Systems for Oracle: Version 7.0.0(Build76) Starting restore at 09-MAY-10 channel t1: looking for autobackup on day: 20100509 channel t1: autobackup found: c-3941155360-20100509-01 released channel: t1 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of restore command at 05/09/2010 18:01:35 ORA-19870: error reading backup piece c-3941155360-20100509-01 ORA-19507: failed to retrieve sequential file, handle="c-3941155360-20100509-01", parms="" ORA-27029: skgfrtrv: sbtrestore returned error ORA-19511: Error received from media manager layer, error text: sbtrestore: Job[0] thread[26316]: InitializeCLRestore() failed.

• Configuring ASP.NET MVC2 on Apache 2.2 using mod_aspdotnet

  - by user40684

  Trying to get an MVC2 website to run on Apache 2.2 web server (running on Windows) that utilizes the mod_aspdotnet module. Have several ASP.NET Virtual Hosts running, trying to add another. MVC2 has NO default page (like the first version of MVC had e.g default.aspx). I have tried various changes to the config: commented out 'DirectoryIndex', changed it to '/'. Set 'ASPNET' to 'Virtual', will not load first page, always get: '403 Forbidden, You don't have permission to access / on this server.' Below is from my http.conf: LoadModule aspdotnet_module "modules/mod_aspdotnet.so" AddHandler asp.net asax ascx ashx asmx aspx axd config cs csproj licx rem resources resx soap vb vbproj vsdisco webinfo <IfModule aspdotnet_module> # Mount the ASP.NET /asp application #AspNetMount /MyWebSiteName "D:/ApacheNET/MyWebSiteName.com" Alias /MyWebSiteName" D:/ApacheNET/MyWebSiteName.com" <VirtualHost *:80> DocumentRoot "D:/ApacheNET/MyWebSiteName.com" ServerName www.MyWebSiteName.com ServerAlias MyWebSiteName.com AspNetMount / "D:/ApacheNET/MyWebSiteName.com" # Other directives here <Directory "D:/ApacheNET/MyWebSiteName.com"> Options FollowSymlinks ExecCGI AspNet All #AspNet Virtual Files Directory Order allow,deny Allow from all DirectoryIndex default.aspx index.aspx index.html #default the index page to .htm and .aspx </Directory> </VirtualHost> # For all virtual ASP.NET webs, we need the aspnet_client files # to serve the client-side helper scripts.

• Cannot open TUN/TAP dev /dev/as0t0: No such file or directory (errno=2)

• 4in6 tunneling (via OpenVPN?)

  - by Deshene

  I have a local network with internet access. But unfortunately IPv4 internet connection speed is limited to 1mbps, which is realy sad. Fortunately I have a native IPv6, and there is no connection speed limit over IPv6. So, in order to get a good internet connection I made a plan: connect to the VPN-service over IPv6, and pass all IPv4 traffic through IPv6 tunnel, or something like that, I think you get the idea. I suggested to use service like HideMyAss.com, but unfortunately they don't support IPv6. The question is: Is there any existing VPN service that will make my dreams come true, and is easy to use, which I could connect over PPTP or OpenVPN (I want to set up connection to VPN in my router settings). Edit: It seems like there are couple of VPN services that supports IPv6 (it's odd, but the biggest VPN services support only IPv4), and there is none providing 4in6 tunnels. So, I came to the following solution: rent a VPS with IPv6 address, and manually setup 4in6 tunnel. I'm not good at networking, never did things like that, and don't know where to start, and what should I do. The use case, as I undestand, should look like this: I connect from my home computer to the VPS via OpenVPN, and after that all my IPv4 traffic pass through IPv6 (server do the job). OpenVPN - because I want to configure VPN connection to server in my router (Asus RT-N16?). How can I achieve this?

• PHP-FPM and APC for shared hosting?

  - by Tiffany Walker

  We are looking into finding a way to get APC to only create one cache per account / site. This can be done with Fastcgi (last update 2006…) but with Fastcgid APC will have to create multiple caches for multiple processes run by the same account. To get around this problem, we have been looking into PHP-FPM PHP process manager allows multiple PHP processes to share a single APC cache. But from what I have read (I hope I'm wrong) , even if you create a pool per process, all sites accross all pools will share the same APC cache. This brings us back to the same problem as with shared Memcached: it's not secure ! On php-fpm's site I read that you can chroot php-fpm pools and define a specific UID and GID per pool… if this is the case then shouldn't APC have to use this user and not have access to other pools cache ? An article here (in 2011) suggests that you would need to run one process per pool creating multiple launchers on different ports and different config files with one pool per config file : http://groups.drupal.org/node/198168 Is this still neceessary ? If so what would be the impact of running say 800 processes of php-fpm ? Would it be mainly memory ? If so how can I work out what the memory impact would be ? I guess that it would be better to run 800 times php-fpm then to have accounts creating multiple APC caches for a single site ? If on average an account creates a 50MB cache and creates 3 caches per account that makes 150Mb per account which makes 120GB… However if each account uses on average only 50Mb that would make 40GB We will have at least 128GB of ram on our next server so 40GB is acceptable if running 800 x PHP-FPM does not create an overhead of more than 20GB ! What do you think is PHP-FPM the best way to go to provide secure APC cache on shared hosting with a server that has a decent amount of memory ? Or should I be looking at another system ? Thanks !

• Vista Power Management GPO

  - by Matt

  Hi, I've created a loopback GPO that has several settings (both computer and user) including a Custom User Interface (Access 2007 Application) and Power Management (has the computer sleep after being idle for 2 min). I'm also filtering so that this policy does not apply to "Admins" - only to "Users". The problem I'm having is when the "Users" login the Power Management settings don’t work, but they do for "Admins". For testing I'm allowing the "Users" to launch Task Manager and use the Run line, so I'll run Explorer and look at Power Management and it shows the settings from my GPO. So I created a test OU with copies of the aforementioned GPO, but removed the Custom User Interface and found the Power Management settings do work for both the "Users" and "Admins". When I add the Custom UI the Power Management settings break for the "User" but continue to work for "Admins". Do the Power Management options need to have User Interface be "Explorer.exe"? Is this a bug or am I doing this the wrong way? BTW the tablets are using Vista SP2. Any insight or advice would be greatly appreciated. Thanks, Matt

• QoS for Cisco Router to Prioritize Voice and Interactive Traffic

  - by TJ Huffington

  I have a Cisco 891W NATing Voice and Data to the internet over a 10mbit/2mbit connection. Voice traffic gets degraded when I upload large files. Pings time out as well. I tried to configure a QoS policy but it's basically not doing anything. Voice traffic still degrades when upload bandwidth gets saturated. Here is my current configruation: class-map match-any QoS-Transactional match protocol ssh match protocol xwindows class-map match-any QoS-Voice match protocol rtp audio class-map match-any QoS-Bulk match protocol secure-nntp match protocol smtp match protocol tftp match protocol ftp class-map match-any QoS-Management match protocol snmp match protocol dns match protocol secure-imap class-map match-any QoS-Inter-Video match protocol rtp video class-map match-any QoS-Voice-Control match access-group name Voice-Control policy-map QoS-Priority-Output class QoS-Voice priority percent 25 set dscp ef class QoS-Inter-Video bandwidth remaining percent 10 set dscp af41 class QoS-Transactional bandwidth remaining percent 25 random-detect dscp-based set dscp af21 class QoS-Bulk bandwidth remaining percent 5 random-detect dscp-based set dscp af11 class QoS-Management bandwidth remaining percent 1 set dscp cs2 class QoS-Voice-Control priority percent 5 set dscp ef class class-default fair-queue interface FastEthernet8 bandwidth 1024 bandwidth receive 20480 ip address dhcp ip nat outside ip virtual-reassembly duplex auto speed auto auto discovery qos crypto map mymap max-reserved-bandwidth 80 service-policy output QoS-Priority-Output crypto map mymap 10 ipsec-isakmp set peer 1.2.3.4 default set transform-set ESP-3DES-SHA match address 110 qos pre-classify ! fa8 is my connection to the internet. Voice traffic goes over a VPN ("mymap") to the SIP server. That's why I specified "qos pre-classify" which I believe is the way to classify traffic over the VPN. However even when I ping a public IP while saturating upload bandwidth, the latency is exceptionally high. Is this configuration correct? Are there any suggestions that might make this work for my setup? Thanks in advance.

  I have a c-compiled CGI application that I need to execute from the DocumentRoot of my Apache server. The CGI file is called index.cgi and is located at /usr/lib/cgi-bin/index.cgi. I have the following Directory definition <Directory "/usr/lib/cgi-bin/"> Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch AllowOverride None Order allow,deny Allow from all DirectoryIndex index.cgi </Directory> I have the following VirtualHost setting: <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /usr/lib/cgi-bin # ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined </VirtualHost> If I go to 127.0.0.1 or 127.0.0.1/index.cgi I get prompted to download the index.cgi file, however if I enable the ScriptAlias in the vhost configuration block and go to 127.0.0.1/cgi-bin/index.cgi I see the output of my CGI application. I had originally solved this problem with mod_rewrite, however that worked on my test system the target (embedded) doesn't have that module available so I'm looking at another route (again).

• Mouse wheel in VirtualPC (mostly) does not work on 64-bit Windows 7 RC

  - by JonStonecash

  I have recently upgraded my laptop from WinXP Pro (32-bit) to Windows 7 RC (64-bit). I have a number of VirtualPC 2007 images that I use for testing on various platforms and looking at beta software. I have installed the 64-bit version of VirtualPC. The images all work with the exception of the mouse wheel within the virtual machine. I have tried this out with WinXP Pro, Windows 7 RC, and Windows Server 2008 images. All are 32-bit and all exhibit the same behavior: a gentle rotation of the wheel does nothing; a quick rotation of the wheel sometimes gets a scroll and sometimes not. I regard this behavior as unusable as I tend to use the mouse wheel a lot. All of this worked just fine on WinXP. I have re-installed the Virtual machine additions on all of the machines. The Windows 7 RC virtual image was created after the upgrade to Windows 7 and the 64-bit version of VirtualPC (just to isolate the possibility that I had corrupted the images during the transition). I have googled, binged, and yahoo-ed. There are scattered mentions of this problem (dating back to VPC 2004) but no solutions. I am aware that I could start up one of these images and then use remote desktop connections to get access to that image. I, in fact, do just that for some development that I am doing; the mouse works just fine. This is acceptable in this case because I spend hours at a time in the development VM. These test environments are different in that I will bring up an image for just a short time: minutes rather than hours. Adding the rdc step is much more significant in these cases. Does anyone have any idea of what to do next?

• Trying to reconcile global ip address and Vhosts

  - by puk

  I have been using my local machine as a web server for a while, and I have several websites set up locally on my machine, all with similar Vhost files like the one seen here /etc/apache2/sites-available/john.smith.com: <VirtualHost *:80> RewriteEngine on RewriteOptions Inherit ServerAdmin [email protected] ServerName john.smith.com ServerAlias www.john.smith.com DocumentRoot /home/john/smith # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn LogFormat "%v %l %u %t \"%r\" %>s %b" comonvhost CustomLog /var/log/apache2/access.log comonvhost </VirtualHost> then I set up the /etc/hosts file like so for every Vhost: 192.168.1.100 www.john.smith.com john.smith.com 192.168.1.100 www.jane.smith.com jane.smith.com 192.168.1.100 www.joe.smith.com joe.smith.com 192.168.1.100 www.jimbob.smith.com jimbob.smith.com Now I am hosting my friend's website until he gets a permanent domain. I have port forwarding set up to redirect port 80 to my machine, but I don't understand how the global ip fits into all of this. Do I for example use the following web site addresses (assume global ip is 12.34.56.789): 12.34.56.789.john.smith 12.34.56.789.jane.smith 12.34.56.789.joe.smith 12.34.56.789.jimbob.smith

• Bypassing Router's DNS Settings

  - by Ramon Marco Navarro

  Is there a way to bypass my ISP provided CPE/router's DNS settings? I'd like to use OpenDNS but I am unable to access the administrator acount of the CPE. I tried logging in using the default passwords (admin/admin, admin/1234, etc) to no avail. I found out later that the admin password is generated using a generator where you input the CPE's MAC address. I tried emailing the manufacturer of the CPE (Huawei, the CPE is Huawei BM625) and my ISP but they aren't replying. I also saw similar queries (lots of them!) at Huawei's forums, without a single reply. So as a last resort, I'd like to know a way to bypass the CPE's DNS settings. My subscription is for a WiMAX service. I'm using Windows 7 and have already set the DNS settings for the Local Area Connection. But I still am not seeing the "You are already using OpenDNS" text at OpenDNS's site. And when explicitly using the OpenDNS servers I still seem to get 208.69.38.150 rather than the expected 208.69.38.160: nslookup www.opendns.com. 208.67.222.222 Server: resolver1.opendns.com Address: 208.67.222.222 Non-authoritative answer: Name: www.opendns.com Address: 208.69.38.150

• Indefinite hang when restoring SQL 2005 database on a SQL 2008 server in EC2

  - by erinloy

  I'm trying to restore a 25 GB database backup taken from a Windows 2003/SQL 2005 machine to a Windows 2008/SQL 2008 machine in the Amazon EC2 cloud, using a .bak file and the SQL Management Studio. SQL Management Studio reports the restore reaches 100% complete, and then just hangs indefinitely (24+ hours) using a lot of CPU, until I restart the SQL Server service. Upon restart, SQL again uses a lot of CPU activity for what seems to be an indefinite amount of time, but the DB never comes online. Here are some details: - I have created two EBS volumes, one for DATA and one for LOGS, and I have set the default directories in SQL Server to the \DATA and \LOG directory on these respective volumes. (I wonder if the issue could be related to this, but the DB is too big to restore on the root drive.) - I have given the SQL Server user group full access to these directories. - The server can create a new empty test DB in these directories just fine, and can backup and restore the test DB. - I have tried both restoring of a .bak file and attaching directly to copies of the original .mdf/.ldf files, and the result is the same in both cases. - Both the .bak restore and the .mdf/.ldf attach occur from/to the EBS volumes. - I've also tried the above via SQL script, and "WITH RECOVERY", with no difference in the result, just less UI. - The backup contains two full text indexes. - I have to use "WITH MOVE" for most of the files in the backup. - There's nothing wrong with the backup or .mdf/.ldf files, as this works just fine on a Windows 2003/SQL 2005 machine in the Amazon EC2, but not Windows 2008/SQL 2008. - The DB is NOT marked as "Restoring" in the SQL Management Studio - it is just listed as a normal database, but throws errors when I try to do anything with it (expand the object browser tree, view properties, etc.) Any ideas?

• Wacom consumer tablet driver service may crash while opening Bamboo Preferences, often after resuming computer from sleep

  - by DragonLord

  One of the ExpressKeys on my Wacom Bamboo Capture graphics tablet is mapped to Bamboo Preferences, so that I can quickly access the tablet settings and view the battery level (I have the Wireless Accessory Kit installed). However, when I connect the tablet to the computer, in wired or wireless mode, and attempt to open Bamboo Preferences, the Wacom consumer tablet driver service may crash, most often when I try to do so after resuming the computer from sleep. There is usually no direct indication of the crash (although I once did get Tablet Service for consumer driver stopped working and was closed), only that the cursor shows that the system is busy for a split second. When this happens, the pen no longer tracks on the screen when in proximity of the tablet (even though it is detected by the tablet itself); however, touch continues to function correctly. To recover from this condition, I need to restart the tablet driver services. I got tired of having to go through Task Manager to restart the service every time this happens, so I ended up writing the following command script, with a shortcut on the desktop for running it with elevated privileges: net stop TabletServicePen net start TabletServicePen net stop TouchServicePen net start TouchServicePen Is there something I can do to prevent these crashes from happening in the first place, or do I have have to deal with this issue until the driver is updated? Windows 7 Home Premium 64-bit. Tablet drivers are up to date. Technical details Action Center gives the following details about the crash in Reliability Monitor: Source Tablet Service for consumer driver Summary Stopped working Date ?10/?15/?2012 2:48 PM Status Report sent Description Faulting Application Path: C:\Program Files\Tablet\Pen\Pen_Tablet.exe Problem signature Problem Event Name: APPCRASH Application Name: Pen_Tablet.exe Application Version: 5.2.5.5 Application Timestamp: 4e694ecd Fault Module Name: Pen_Tablet.exe Fault Module Version: 5.2.5.5 Fault Module Timestamp: 4e694ecd Exception Code: c0000005 Exception Offset: 00000000002f6cde OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 1033 Additional Information 1: 9d4f Additional Information 2: 9d4f1c8d2c16a5d47e28521ff719cfba Additional Information 3: 375e Additional Information 4: 375ebb9963823eb7e450696f2abb66cc Extra information about the problem Bucket ID: 45598085 Exception code 0xC0000005 means STATUS_ACCESS_VIOLATION.

• ADSIEdit Cleanup After Exchange 2003 Crash During Transition To Exchange 2010

  - by ThaKidd

  Hello all. I would value some input from a few Exchange 2010 experts. I have almost completed the transition from Exchange 2003 Standard to Exchange 2010 Standard. Everything went smoothly until I tried to uninstall Exchange 2003. At that point the server bit the dust and died completely. I now have NO access to the old Exchange System Management MMC as I am running Windows 2008 SR2 and Windows 7 only. I can only fix this with ADSIEdit, EMShell, and EMConsole. I have used the 2010 shell to move/remove/verify that all mailboxes, public folders and OAB are hosted on Exchange 2010. I also verified that the routing connector has been deleted. The only two things that were not done was to remove the Recipient Update Service and actually perform the removal of the 2003 software. I have spent a lot of time going through ASDIedit and have located the old Administrative Group and the Exchange 2003 server listed under it. I also located the Recipient Update Service which includes two entries; Enterprise and my domain name. I have read that it is an unwise idea to remove the old administrative group so I won't bother messing with that. I am repeatedly getting three warnings in the Application Log. Both are from MSExchangeTransport EventID 5006 (Cannot find route to Mailbox Server OLDSERVER) and 5020 (The topology doesn't contain a route to Exchange 2000 Server or Exchange Server 2003) So my questions are: To clean out AD of the old Exchange 2003 info, can I delete the server name folder (Configuration - Services - Microsoft Exchange - ExchOrg - Administrative Groups - First Administrative Group - Servers - Old Server) and also delete the Update Recipient Service (Enterprise) and Update Recipient Service (DOMAIN) containers safely? Are there any additional items I need to address to ensure the AD is clean? Thanks in advance for your help!

• CVSROOT problem because of username string

  - by jatanp

  Hi, I have always been SVN user but currently I have to use CVS as the source repository. I am quite new to CVS and really got confused many a times (reason being I always tried to access CVS like SVN !) However now I am really stuck in one problem wherein I am not able to do any cvs operations through cygwin. Actually I have checked out the code using WinCVS and while doing that it created the CVSROOT as following, :pserver;username=<user_name>;password=<pwd>:<serverip>:/cvs/repository However whenever I try to use cvs command in cygwin (after setting CVSROOT variable using export) it fails with following error: cvs update: Unknown option (`username') in CVSROOT. cvs update: in directory .: cvs update: ignoring CVS/Root because it does not contain a valid root. cvs update: Unknown option (`username') in CVSROOT. cvs [update aborted]: Bad CVSROOT: `:pserver;username=<user_name>;password=<pwd>:<serverip>:/cvs/repository'. However the command works fine, if invoked through dos command prompt. I got to know that on DOS prompt, cvs command is provided by CVSNT whereas in cygwin it's some different package. Please let me know where I have made a mistake and how it can be corrected ! I need cvs to work inside cygwin for some scripting purpose.
