• How do I connect two computers with a LAN cable?

  - by John

  I have two machines - Windows XP and a laptop using Windows 7. I connected them with a WLAN cable. On the Windows XP machine, I set the IP address to 192.168.0.10. On the Windows 7 laptop, I set the IP address to 192.168.0.20. The laptop can see the Windows XP machine, but Windows XP machine cannot see the Windows 7 machine. But this does NOT concern me. I want to move the files from my desktop (Windows XP) to Windows 7 (laptop). That's why I'm going through all this. The problem is that when I try to connect from Windows 7 to Windows XP machine, I get this window: I don't understand what username/password is needed. I use none on the Windows XP machine. I tried all usernames - no success. Please explain in deep details how to solve my problem so I can connect to my Windows XP machine. EDIT: Maybe this can help: the Windows XP machine is named 'I' and '???????? III' is the name of the laptop. Both computers share one workgroup - WORKGROUP.

• Enable PasswordAuthentication on OpenSuse 10

  Hi, I've a virtual instance of Suse 10 running in my VMWare player, and I'm fighting against it to allow ssh password authentcation.

• Can't start Bind9 on Ubuntu 10.04 + Plesk 10.1 - "named: no process found"

  - by bradley.ayers

  I've installed a fresh version of Ubuntu 10.04 64bit, I didn't install bind when choosing what packages should be installed in the Ubuntu installer. I downloaded the auto installer for Plesk 10.1 and installed it successfully. When I logged into the Plesk control panel and tried to change the password, it failed because it couldn't restart bind. I SSH'd into the box and tried a sudo /etc/init.d/bind9 restart and get the following: brad@ws01:/root# sudo /etc/init.d/bind9 restart * Stopping domain name service... bind9 WARNING: key file (/etc/bind/rndc.key) exists, but using default configuration file (/etc/bind/rndc.conf) rndc: connect failed: 127.0.0.1#953: connection refused named: no process found [ OK ] * Starting domain name service... bind9 [fail] Looking at tail /var/log/messages reveals a whole bunch of: Feb 23 16:08:21 ws01 kernel: [ 3840.065851] type=1503 audit(1298441301.831:31): operation="open" pid=5565 parent=5563 profile="/usr/sbin/named" requested_mask="::r" denied_mask="::r" fsuid=108 ouid=0 name="/var/named/run-root/etc/named.conf" Edit: After following ooshro's advice, bind runs, however I still get the named: no process found error: brad@ws01:/etc/apparmor.d$ sudo /etc/init.d/bind9 restart * Stopping domain name service... bind9 WARNING: key file (/etc/bind/rndc.key) exists, but using default configuration file (/etc/bind/rndc.conf) named: no process found [ OK ] * Starting domain name service... bind9 [ OK ]

• SQL Server 2008 Unique Problem for bring DB Online...

  - by Nai

  This is my error I am facing TITLE: Microsoft.SqlServer.Smo Set offline failed for Database 'Go3D_Retailer ------------------------------ ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) Unable to open the physical file "E:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\ftrow_Go3D_catalog.ndf". Operating system error 2: "2(failed to retrieve text for this error. Reason: 15105)". Database 'Go3D_Retailer' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. ALTER DATABASE statement failed. (Microsoft SQL Server, Error: 5120) Background to this error I've been trying to move my destination logshipping database to another physical server for analysis purposes. Because I do not have active directory set up, I had to hack my process by using the same username/password for both the source and destination servers to get the process to work. Following that, I used this guy's solution to move the destination database to another server. However, this error occurs when I try to bring the database back online. I don't have an E drive on my server and I have no idea why it's trying to open a file from E drive. I have over a 100gb left on my hard disk so it's definitely not a space issue. This sounds like a bug... Any ideas? I'm running SQL Server 2008 Enterprise edition on Windows Server 2008 R2 64bit

• Don't let the mouse wake up displays from standby

  - by progo

  I like to put my displays to powersave/standby mode when I leave the computer for a while. It would be ok if it weren't for oversensitive mouse. Sometimes the driver reads in some movement that's not visible to the naked eye (the cursor, that is) and it breaks the power save. It would wait for another 10 minutes before going back to its standby. My workaround is the following script bound to C-S-q: xlock -startCmd 'xset dpms 2 2 2' -endCmd 'xset dpms 600 1200 1300' -mode blank -echokeys -timeelapsed +usefirst By using xset I set the values to 2 seconds each before going to standby. It's not nice, anyway. Sometimes there are cool fortunes that I want to read before typing in the password. I could keep the cursor moving but it's cludgy. (By the way, xlock's option mousemotion doesn't help -- it just hides the cursor but the displays fire up nevertheless.) So the question: is there a way to make displays go standby and stay there until a keyboard key is pressed? I'm running gentoo and recent Xorg, but I hope the answer doesn't have to be distro-specific. Basically the answer can be as simple as how to enable/disable mouse within command line? It think that would do the job if DPMS doesn't know the idea.

• saslauthd authentication error

  - by James

  My server has developed an expected problem where I am unable to connect from a mail client. I've looked at the server logs and the only thing that looks to identify a problem are events like the following: Nov 23 18:32:43 hig3 dovecot: imap-login: Login: user=, method=PLAIN, rip=xxxxxxxx, lip=xxxxxxx, TLS Nov 23 18:32:55 hig3 postfix/smtpd[11653]: connect from xxxxxxx.co.uk[xxxxxxx] Nov 23 18:32:55 hig3 postfix/smtpd[11653]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory Nov 23 18:32:55 hig3 postfix/smtpd[11653]: warning: xxxxxxx.co.uk[xxxxxxxx]: SASL LOGIN authentication failed: generic failure Nov 23 18:32:56 hig3 postfix/smtpd[11653]: lost connection after AUTH from xxxxxxx.co.uk[xxxxxxx] Nov 23 18:32:56 hig3 postfix/smtpd[11653]: disconnect from xxxxxxx.co.uk[xxxxxxx] The problem is unusual, because just half an hour previously at my office, I was not being prompted for a correct username and password in my mail client. I haven't made any changes to the server, so I can't understand what would have happened to make this error occur. Searches for the error messages yield various results, with 'fixes' that I'm uncertain of (obviously don't want to make it worse or fix something that isn't broken). When I run testsaslauthd -u xxxxx -p xxxxxx I also get the following result: connect() : No such file or directory But when I run testsaslauthd -u xxxxx -p xxxxxx -f /var/spool/postfix/var/run/saslauthd/mux -s smtp I get: 0: OK "Success." I found those commands on another forum and am not entirely sure what they mean, but I'm hoping they might give an indication of where the problem might lie. If it makes any difference, I'm running Ubuntu 10.04.1, Postfix 2.7.0 and Webmin/ Virtualmin.

• What is the advantage of not running as root? [closed]

  - by Shmuel Brill

  Possible Duplicate: What's wrong with always being root? All modern brands of Linux highly discourage (or disable) one from running as root instead of a normal user. I do not understand why. As a "normal" user, one could Download a rouge program from the internet. Run it (After all, one isn't root, what can it do). It installs itself in .bashrc or .xinitrc It writes a rouge "sudo" and "su" and adds . to the path Not noticing that . is in path, one runs sudo. The rouge program now has root password and can do anything it wants in the system. Even if 3-6 doesn't happen, the program could still Be part of a botnet. Read all files in the home directory and send them back (mine for SS#, Credit Card numbers, bank account numbers, etc). Send spam. Run a backdoor server to allow an attacker a chance to connect to the machine to determine vulnerabilities. It seems that the whole "permissions" thing (root/non-root) is just to prevent amateur crackers from getting into the system, so the question is: Is there a point in avoiding running as root, and is there a way to protect oneself if one wants to run unsafe code?

• What's the right way to create a Ubuntu user whose home directory is /var/www/SITE?

  - by Leonnears

  First of, I need to state I'm a complete ignorant when it comes to server administration on Ubuntu, and I'm doing what I can. I have been trying to do this for hours with no luck. Basically, I want to create a Ubuntu user whose home directory is /var/www/SITE, and prefered it is chroot'd to it. The chroot part is not so important right now, as first I prefer to make anything work. The user should be able to upload files here and the webserver (www-data user?) should be able to pick them up with no problem. I was able to create the user and give it the home directory /var/www/SITE. (the user is "anders"). I gave him a password, and "anders" can connect to FTP just fine and upload files. But here's where things don't work: While my user can upload files to that /var/www/SITE directory, when I access the webpage on my browser I get a Forbidden error. Note that anders is also a member of the www-data group. I can fix this by running sudo chmod g+s /var/www/SITE/* anders -R but this is of course not ideal. Ideally the files should "work" as soon as I upload them. What's the right way to fix this? If it matters (don't think so), I'm editing my files in Coda 2 and anders is the user for it.

• SSH public key authentication -- always require users to generate their own keypair?

  - by schinazi

  I was working with a partner today that I needed to upload files to my server using scp. I have passwords turned off in the server's SSH configuration, so I wanted them to use public key authentication. I generated the keypair for them on the server and gave them the private key and put the public key in the appropriate authorized_keys file. After a bunch of problems with them setting up their job, they finally got a more experienced sysadmin involved on their end, and he scolded me for handling the key generation this way. He said that by giving them a private key generated on my system, I had enabled them to do a brute-force attack against other keys generated on the same server. I even asked him "so if I have an account on a server, and I can log in with a password but I want to automate something and I generate a keypair on that system, does that then give me an attack vector for brute forcing other users' keys?" and he said yes. I've never heard of this, is it true? Can anyone point me to a discussion of this attack? Thanks in advance.

• What's the best way to telnet from a remote Windows PC without using RDP?

  - by Rob D.

  Three Networks: 10.1.1.0 - Mine 172.1.1.0 - My Branch Office 172.2.2.0 - My Branch Office's VOIP VLAN. My PC is on 10.1.1.0. I need to telnet into a Cisco router on 172.2.2.0. The 10.1.1.0 network has no routes to 172.2.2.0, but a VPN connects 10.1.1.0 to 172.1.1.0. Traffic on 172.1.1.0 can route to 172.2.2.0. All PCs on 172.1.1.0 are running Windows XP. Without disrupting anyone using those PCs, I want to open a telnet session from one of those PCs to the router on 172.2.2.0. I've tried the following: psexec.exe \\branchpc telnet 172.2.2.1 psexec.exe \\branchpc cmd.exe telnet 172.2.2.1 psexec.exe \\branchpc -c plink -telnet 172.2.2.1 Methods 1 and 2 both failed because telnet.exe is not usable over psexec. Method 3 actually succeeded in creating the connection, but I cannot login because the session registers my carriage return twice. My password is always blank because at the "Username:" prompt I'm effectively typing: Routeruser[ENTER][ENTER] It's probably time to deploy WinRM... Does anyone know of any other alternatives? Does anyone know how I can fix plink.exe so it only receives one carriage return when I use it over psexec?

• Nginx with PAM authentication through pam_script

  - by Envek

  Have anyone set up such a configuration? It's not work for me. So, I've installed nginx-extras on Ubuntu 12.04 (it's built with PAM module), and write to site config: location ^~ /restricted_place/ { auth_pam "Please specify login and password from main_site"; auth_pam_service_name "nginx"; } Afterwards, in /etc/pam.d/nginx: auth required pam_script.so dir=/path/to/my/auth_scripts And wrote simplest /path/to/my/auth_scripts/pam_script_auth (also I've tried to write complicated scripts) #!/bin/sh exit 0 # should allow anyone Doesn't work. The script is launched (I've wrote full functional script, that successfully executes, check credentials, writes to its own log and returns correct exit code, and executes noticeably long). But no access granted. Only rejected. In /var/log/nginx/error.log appears next record: 2012/09/13 10:44:42 [alert] 1666#0: waitpid() failed (10: No child processes) If I'm specify in /etc/pam.d/nginx: auth required pam_unix.so and grant for www-data user right to read /etc/shadow, unix authorization works fine. But script auth doesn't work. Can't understand, where is trouble. In nginx module, or in pam_script module.

• Unable to install PEM/pkcs12 created by gnutls to Cisco ASA

  - by ACiD GRiM

  I've been pulling some hair out trying to figure out why cisco devices don't like my certificates. My primary need is to get a trustpoint set up with CA,cert,key on the ASA for VPN systems, however I'm having the same issues on my IOS devices. I created a pkcs12 with openssl a few months ago that imported with no issues, but now that I'm getting ready to move this lab to production I'm using gnutls certtool as I found it adds alt_dns and ip_address fields properly to the certificate, (which cost me a few more hairs trying to get to work with openssl's ca tool) I'm including the current test certs below, don't worry I'm not using these in production ;) The maddening thing is that after I thought gnutls was generating certs incorrectly, I tried making a pkcs12 for a printserver and it imported with no issues. Here's my command flow for creating these certs: certtool --generate-privkey --disable-quick-random --outfile nn-ca.key certtool --generate-self-signed --load-privkey nn-ca.key --outfile nn-ca.crt certtool --generate-privkey --disable-quick-random --outfile nn-g0.key certtool --generate-certificate --load-privkey nn-g0.key --outfile nn-g0.crt --load-ca-privkey nn-ca.key --load-ca-certificate nn-ca.crt openssl pkcs12 -export -certfile nn-ca.crt -in nn-g0.crt -inkey nn-g0.key -out nn-g0.p12 openssl enc -base64 -in nn-g0.p12 -out nn-g0.base64.p12 The password for the attatched pkcs12 is "ciscohelp" without quotes. Thanks for any help TestCerts

• Accessing network shares on Windows7 via SonicWall VPN client

  - by Jack Lloyd

  I'm running Windows7 x64 (fully patched) and the SonicWall 4.2.6.0305 client (64-bit, claims to support Windows7). I can login to the VPN and access network resources (eg SSH to a machine that lives behind the VPN). However I cannot seem to be able to access shared filesystems. Windows is refusing to do discovery on the VPN network. I suspect part of the problem is Windows persistently considers the VPN connection to be a 'public network'. Normally, you can open the network and sharing center and modify this setting, however it does not give me a choice for the VPN. So I did the expedient thing and turned on file sharing for public networks. I also disabled the Windows firewall for good measure. Still no luck. I can access the server directly by putting \\192.168.1.240 in the taskbar, which brings up the list of shares on the server. However, trying to open any of the shares simply tells me "Windows cannot access \\192.168.1.240\share You do not have permission to access ..."; it never asks for a domain password. I also tried Windows7 native VPN functionality - it couldn't successfully connect to the VPN at all. I suspect this is because SonicWall is using some obnoxious special/undocumented authentication system; I had similar problems trying to connect on Linux with the normal IPsec tools there. What magical invocation or control panel option am I missing that will let this work? Are there any reasonable debugging strategies? I'm feeling quite frustrated at Windows tendency to not give me much useful information that might let me understand what it is trying to do and what is going wrong.

• Deploying a Git server in a AWS linux instance

  - by Leroux

  I'm making a git server on my linux instance in AWS. I tried doing it using these instructions but in the end I always get stuck with a "Permission denied (publickey)" message. So here is my detailed steps, the client is my windows machine running mysysgit and the server is the AWS ubuntu instance : 1) I created user Git with a simple password. 2) Created the ssh directory in ~/.ssh 3) On the client I created ssh keys using ssh-keygen -t rsa -b 1024, they got dropped in my /Users/[Name]/.ssh directory, id_rsa and id_rsa.pub key pair was created. 4) Using notepad I copy pasted the text into newly created files on the server in the ~/.ssh directory of my Git user. ~/.ssh/id_rsa and **~/.ssh/id_rsa.pub** were copied. 5) On the server I made the authorized_hosts file using "cat id_rsa.pub authorized_hosts" (while inside the .ssh directory) 6) Now to test it, on my client machine I did ssh -v git@[ip.address] 7) Result : debug1: Host 'ip.address' is known and matches the RSA host key. debug1: Found key in /c/Users/[Name]/.ssh/known_hosts:1 debug1: ssh_rsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Trying private key: /c/Users/[Name]/.ssh/identity debug1: Trying private key: /c/Users/[Name]/.ssh/id_rsa debug1: Offering public key: /c/Users/[Name]/.ssh/id_dsa debug1: Authentications that can continue: publickey debug1: No more authentication methods to try.

• Run Explorer in SYSTEM account on Windows Vista or 7 using Sysinternal’s psexec tool?

  - by Rob

  Has anyone been successful at launching an instance of Windows Explorer in the SYSTEM account on Windows Vista or 7? It is possible to do this on XP, but I haven't been able to get it to completely work in Vista or 7. Trying to launch Explorer as SYSTEM into session 1 (my user session) results in Explorer exiting immediately and returning an error code of 1. I can launch Explorer as SYSTEM into session 0 with the following command: psexec -i 0 -s explorer That will create an instance of explorer running as SYSTEM with a taskbar and start menu on the hidden session 0 desktop, but won't let you open a file browser window. If you switch to the hidden session 0 desktop and try to open an Explorer window from there to browse files, the following error message appears: "The server process could not be started because the configured identity is incorrect. Check the username and password." I have set the following registry key to 1 for my user account and the SYSTEM account: \Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\SeparateProcess There has got to be a way to make this work? If it is not possible, can anyone explain why? -Rob

• Windows file sharing with a private LAN when a public VPN is connected?

  - by netvope

  OS: Windows Vista My LAN interface is configured as a "private network". I want to have all the sharing and discovery features (Network Discovery, File Sharing, Public Folder Sharing, Printer Sharing, Password Protected Sharing, and Media Sharing), so I enabled them all. My VPN interfaces are configured as "public networks", and I do NOT want to have any of the above features. Now the problem is that if I disabled these sharing features while a VPN is connected, it affects both interfaces. I guess the Network and Sharing Center is probably an oversimplified tool that may not support multiple interfaces. Where can I tell Windows to enable sharing features for the private networks and not the public networks? For file sharing, I think I can disable "File and Printer Sharing for MS Networks" in each of the VPNs' properties. However, I will need to disable it every time I add a new VPN. Moreover, I can't find how to disable Media Sharing by this way. If this can be more easily done in Windows XP or 7, please let me know.

• Fedora, ssh and sudo

  - by Ricky Robinson

  I have to run a script remotely on several Fedora machines through ssh. Since the script requires root priviliges, I do: $ ssh me@remost_host "sudo touch test_sudo" #just a simple example sudo: no tty present and no askpass program specified The remote machines are configured in such a way that the password for sudo is never asked for. For the above error, the most common fix is to allocate a pseudo-terminal with the -t option in ssh: $ ssh -t me@remost_host "sudo touch test_sudo" sudo: no tty present and no askpass program specified Let's try to force this allocation with -t -t: $ ssh -t -t me@remost_host "sudo touch test_sudo" sudo: no tty present and no askpass program specified Nope, it doesn't work. In /etc/sudoers of course I have this line: #Defaults requiretty ... but I can't manually change it on tens of remote machines. Am I missing something here? Is there an easy fix? EDIT: Here is the sudoers file of a host where ssh me@host "sudo stat ." works. Here is the sudoers file of a host where it doesn't work. EDIT 2: Running tty on a host where it works: $ ssh me@host_ok tty not a tty $ ssh -t me@host_ok tty /dev/pts/12 Connection to host_ok closed. $ ssh -t -t me@host_ok tty /dev/pts/12 Connection to host_ok closed.

• Firefox and Chrome keeps forcing HTTPS on Rails app using nginx/Passenger

  - by Steve

  I've got a really weird problem here where every time I try to browse my Rails app in non-SSL mode Chrome (v16) and Firefox (v7) keeps forcing my website to be served in HTTPS. My Rails application is deployed on a Ubuntu VPS using Capistrano, nginx, Passenger and a wildcard SSL certificate. I have set these parameters for port 80 in the nginx.conf: passenger_set_cgi_param HTTP_X_FORWARDED_PROTO http; passenger_set_cgi_param HTTPS off; The long version of my nginx.conf can be found here: https://gist.github.com/2eab42666c609b015bff The ssl-redirect.include file contains: rewrite ^/sign_up https://$host$request_uri? permanent ; rewrite ^/login https://$host$request_uri? permanent ; rewrite ^/settings/password https://$host$request_uri? permanent ; It is to make sure those three pages use HTTPS when coming from non-SSL request. My production.rb file contains this line: # Enable HTTP and HTTPS in parallel config.middleware.insert_before Rack::Lock, Rack::SSL, :exclude => proc { |env| env['HTTPS'] != 'on' } I have tried redirecting to HTTP via nginx rewrites, Ruby on Rails redirects and also used Rails view url using HTTP protocol. My application.rb file contains this methods used in a before_filter hook: def force_http if Rails.env.production? if request.ssl? redirect_to :protocol => 'http', :status => :moved_permanently end end end Every time I try to redirect to HTTP non-SSL the browser attempts to redirect it back to HTTPS causing an infinite redirect loop. Safari, however, works just fine. Even when I've disabled serving SSL in nginx the browsers still try to connect to the site using HTTPS. I should also mention that when I pushed my app on to Heroku, the Rails redirect work just fine for all browsers. The reason why I want to use non-SSL is that my homepage contains non-secure dynamic embedded objects and a non-secure CDN and I want to prevent security warnings. I don't know what is causing the browser to keep forcing HTTPS requests.

• Unable to add datasource in ColdFusion 9 and SQL Server 2008 R2

  - by Evik James

  I just installed SQL Server 2008 R2 and ColdFusion 9.0.1 on my Windows 7 machine for development use only. I have ColdFusion running well and serving pages (that aren't connected to a database). I can view my databases in SQL Server Management Studio. I successfully restored a few small databases and now I am trying to set up datasources for them through the ColdFusion Administrator. On my other machine, this was super easy. Not so much this time. The database I just added is named "Test". I am getting this error: Connection verification failed for data source: Test java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host and port: localhost:1433. Reason: Connection refused: connect The root cause was that: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]Error establishing socket to host and port: localhost:1433. Reason: Connection refused: connect It looks like the connection between ColdFusion and SQL Server is being refused. I know, brilliant observation, right? On my other machine, I was able to create datasources with just the default settings, no server name, username, or password. Any clue as to what might be the cause and how I might fix it?

• Trying to configure DNS on a Godaddy Virtual Dedicated host, Mediatemple Domain Registration [closed]

  - by dclowd9901

  A client of mine purchased VD hosting with Godaddy and a domain name with Mediatemple. I've never configured DNS from scratch, and I'm finding it very difficult to find any sort of explanation on how to go about it. As of right now, Mediatemple is pointing to the Godaddy's ns1.domaincontrol.com and ns2.domaincontrol.com nameservers. The VD hosting on Godaddy (via their Simple Control Panel) has options to "Add a new domain", which brings you through a wizard of sorts that asks you if the domain has already been registered (yes), what it is (dclowd9901.com for this example), create a system username and password for it (with checkboxes for SSH and FTP access), which level of user can administer it, and whether a mail account should be setup. When complete, it also creates a zone file. In this zone file, the Primary nameserver is ns1.dclowd9901.com; the records are as follow (where 12.23.12.34 is the presumed host): @ A 12.23.12.34 @ NS ns1 @ NS ns2 ns1 A 12.23.12.34 ns2 A 12.23.12.34 @ MX mail www A 12.23.12.34 ftp A 12.23.12.34 ssh A 12.23.12.34 mail A 12.23.12.34 If anyone can shed any light on this for me, explain to me the interactions between the registrar and the host and so on, I'd be very grateful. Thanks in advance for the help.

• Kerberos authentication not working for one single domain

  - by Buddy Casino

  We have a strange problem regarding Kerberos authentication with Apache mod_auth_kerb. We use a very simple krb5.conf, where only a single (main) AD server is configured. There are many domains in the forest, and it seems that SSO is working for most of them, except one. I don't know what is special about that domain, the error message that I see in the Apache logs is "Server not found in Kerberos database": [Wed Aug 31 14:56:02 2011] [debug] src/mod_auth_kerb.c(1025): [client xx.xxx.xxx.xxx] Using HTTP/[email protected] as server principal for password verification [Wed Aug 31 14:56:02 2011] [debug] src/mod_auth_kerb.c(714): [client xx.xxx.xxx.xxx] Trying to get TGT for user [email protected] [Wed Aug 31 14:56:02 2011] [debug] src/mod_auth_kerb.c(625): [client xx.xxx.xxx.xxx] Trying to verify authenticity of KDC using principal HTTP/[email protected] [Wed Aug 31 14:56:02 2011] [debug] src/mod_auth_kerb.c(640): [client xx.xxx.xxx.xxx] krb5_get_credentials() failed when verifying KDC [Wed Aug 31 14:56:02 2011] [error] [client xx.xxx.xxx.xxx] failed to verify krb5 credentials: Server not found in Kerberos database [Wed Aug 31 14:56:02 2011] [debug] src/mod_auth_kerb.c(1110): [client xx.xxx.xxx.xxx] kerb_authenticate_user_krb5pwd ret=401 user=(NULL) authtype=(NULL) When I try to kinit that user on the machine on which Apache is running, it works. I also checked that DNS lookups work, including reverse lookup. Who can tell me whats going?

• keyboard intermittently stops working even after reinstalling windows 7; possibly a Chrome issue?

  - by neverskipbreakfast

  My keyboard intermittently stops working. Sometimes a couple of keys will work, but usually none. Sometimes if I mash the ctrl+alt+windows keys randomly for a bit, the keyboard will let me type one more letter before stopping again. Sometimes the keys will open a program menu but usually not. I have even completely wiped my machine and reinstalled windows 7; the problem continues. Specs: Intel iMac (early 2006, 2.0GHz, 2MB RAM, 240GB HD) running ONLY Windows 7 Professional, 32-bit (NOT through boot camp) and using a USB keyboard (Saitek Eclipse II.) Unplugging & reconnecting keyboard does NOT fix it. Connecting a different keyboard does NOT fix it. That one won't work, either. Drivers are up-to-date. Removing and reinstalling drivers does NOT fix it. Restarting the computer does NOT fix it. In fact, when the Windows logon screen appears the keyboard won't work and neither will the icon to pull up the on-screen keyboard. My mouse can click around just fine. I can only log onto a non-password protected account. Generally, logging into as different Windows user fixes it. I can then log back on to my main user account and continue work for a few hours until it happens again. Clearing my Chrome browsing data stopped the problem from recurring for a week or so. I have already REINSTALLED Windows 7 (not just a restore.) The problem returned after 2 days of use. I use Avira free antivirus software, and repeated scans turn up nothing fishy. I suspect it is related to something in Google Chrome because I used my google account to reload all my previous Chrome extensions, saved data, etc. (Chrome Extensions Installed: AdBlock, Better Google Tasks, DropBox, FB Photo Zoom, Google Mail Checker, StayFocusd.) Any ideas? Any at all?
