• Windows 7 pc freezes for an indeterminate amount of time after unlocking

  - by pikes

  Not sure if this type of question is appropriate for this forum, but I've tried everything I can think of to solve this problem aside from format/reinstall. I recently got a new work PC (Dell optiplex 755) with windows 7 professional x64. Standard developer software installed for .net development: VS2008, VS2005, SQL management studio, office 2007, etc. Recently I've been having this weird problem where after I lock my pc, when I try to unlock it, the screen will be black for awhile after unlocking. I can ctl+alt+del and put my password in but then it just goes black. The amount of time on the black screen seems to be related to the amount of time I am away from my PC. If only away a few minutes, it'll take about a minute to get to the desktop. If away for an hour, could take up to 15 minutes. If I lock it and go home for the night, I have to restart my PC in the morning (I've let it sit for an hour after a night of being locked and nothing happened). It doesn't do it every time but definitely the majority of the time. One weird thing I've seen is that if I remote into my machine before trying to log back in it does not do it. I uninstalled all software back to the point when I remember it started happening and it still does it. I was using this PC for a few weeks without this problem happening at all. Anyone know what my next troubleshooting steps could be? My IT department tried to fix it by moving my old profile to another disk and having me log in, effectively recreating a profile from scratch but that didn't solve it. As I said above if this isn't the right forum for these types of questions please let me know. Thanks in advance!

• Juniper’s Network Connect ncsvc on Linux: “host checker failed, error 10”

  - by hfs

  I’m trying to log in to a Juniper VPN with Network Connect from a headless Linux client. I followed the instructions and used the script from http://mad-scientist.us/juniper.html. When running the script with --nogui switch the command that gets finally executed is $HOME/.juniper_networks/network_connect/ncsvc -h HOST -u USER -r REALM -f $HOME/.vpn.default.crt. I get asked for the password, a line “Connecting to…” is printed but then the programm silently stops. When adding -L 5 (most verbose logging) to the command line, these are the last messages printed to the log: dsclient.info state: kStateCacheCleaner (dsclient.cpp:280) dsclient.info --> POST /dana-na/cc/ccupdate.cgi (authenticate.cpp:162) http_connection.para Entering state_start_connection (http_connection.cpp:282) http_connection.para Entering state_continue_connection (http_connection.cpp:299) http_connection.para Entering state_ssl_connect (http_connection.cpp:468) dsssl.para SSL connect ssl=0x833e568/sd=4 connection using cipher RC4-MD5 (DSSSLSock.cpp:656) http_connection.para Returning DSHTTP_COMPLETE from state_ssl_connect (http_connection.cpp:476) DSHttp.debug state_reading_response_body - copying 0 buffered bytes (http_requester.cpp:800) DSHttp.debug state_reading_response_body - recv'd 0 bytes data (http_requester.cpp:833) dsclient.info <-- 200 (authenticate.cpp:194) dsclient.error state host checker failed, error 10 (dsclient.cpp:282) ncapp.error Failed to authenticate with IVE. Error 10 (ncsvc.cpp:197) dsncuiapi.para DsNcUiApi::~DsNcUiApi (dsncuiapi.cpp:72) What does host checker failed mean? How can I find out what it tried to check and what failed? The HostChecker Configuration Guide mentions that a $HOME/.juniper_networks/tncc.jar gets installed on Linux, but my installation contains no such file. From that I concluded that HostChecker is disabled for my VPN on Linux? Are the POST to /dana-na/cc/ccupdate.cgi and “host checker failed” connected or independent? By running the connection over a SSL proxy I found out that the POST data is status=NOTOK (Funny side note: the client of the oh-so-secure VPN does not validate the server’s SSL certificate, so is wide open to MITM attacks…). So it seems that it’s the client that closes the connection and not the server.

• getent passwd fails, getent group works?

  - by slugman

  I've almost got my AD integration working completely on my OpenSUSE 12.1 server. I have a OpenSUSE 11.4 system successfully integrated into our AD environment. (Meaning, we use ldap to authenticate to AD directory via kerberos, so we can login to our *nix systems via AD users, using name service caching daemon to cache our passwords and groups). Also, important to note these systems are in our lan, ssl authentication is disabled. I am almost all the way there. Nss_ldap is finally authenticating with ldap server (as /var/log/messages shows), but right now, I have another problem: getent passwd & getent shadow fails (shows local accounts only), but getent group works! Getent group shows all my ad groups! I copied over the relavent configuration files from my working OpenSUSE 11.4 box: /etc/krb5.conf /etc/nsswitch.conf /etc/nscd.conf /etc/samba/smb.conf /etc/sssd/sssd.conf /etc/pam.d/common-session-pc /etc/pam.d/common-account-pc /etc/pam.d/common-auth-pc /etc/pam.d/common-password-pc I didn't modify anything between the two. I really don't think I need to modify anything, because getent passwd, getent shadow, and getent group all works fine on the OpenSUSE11.4 box. Attempting to restart nscd service unfortunately didn't do much, and niether did running /usr/sbin/nscd -i passwd. Do any of you admin-gurus have any suggestions? Honestly, I'm happy I made it this far. I'm almost there guys!

• Why do I have to log into hotmail twice?

  - by Tony Lee

  I just recently noticed I have to attempt a login into hotmail twice before it succeeds. Although I'm using Google Chrome (3.0.195.21), the symptoms are well described in a Mozilla thread. In short, I'm told: The e-mail address or password is incorrect. Please try again. The thread on mozilla's site that supposed to describe the latest details (and the 1st hit on google when I search for "hotmail login twice") requires an account to read so I'm hoping someone here has a good synopsis of what the cause is. I normally start at hotmail.com, which redirects to login.live.com/.... I can login by starting at mail.live.com, using IE8 or attempting a 2nd login. Oddly, if I start at login.live.com Chrome tells me there is a redirect loop. Does anyone know or have a public link to the root cause of the double login? (it is a hotmail account I'm login into) EDIT - Caused by my 'restricting how 3rd parties can use cookies'. If I allow all cookies, it works first time.

• Security implications of adding www-data to /etc/sudoers to run php-cgi as a different user

  - by BMiner

  What I really want to do is allow the 'www-data' user to have the ability to launch php-cgi as another user. I just want to make sure that I fully understand the security implications. The server should support a shared hosting environment where various (possibly untrusted) users have chroot'ed FTP access to the server to store their HTML and PHP files. Then, since PHP scripts can be malicious and read/write others' files, I'd like to ensure that each users' PHP scripts run with the same user permissions for that user (instead of running as www-data). Long story short, I have added the following line to my /etc/sudoers file, and I wanted to run it past the community as a sanity check: www-data ALL = (%www-data) NOPASSWD: /usr/bin/php-cgi This line should only allow www-data to run a command like this (without a password prompt): sudo -u some_user /usr/bin/php-cgi ...where some_user is a user in the group www-data. What are the security implications of this? This should then allow me to modify my Lighttpd configuration like this: fastcgi.server += ( ".php" => (( "bin-path" => "sudo -u some_user /usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 1, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "4", "PHP_FCGI_MAX_REQUESTS" => "10000" ), "bin-copy-environment" => ( "PATH", "SHELL", "USER" ), "broken-scriptfilename" => "enable" )) ) ...allowing me to spawn new FastCGI server instances for each user.

• Create a wifi hotspot in a place where an authentication is required

  - by SoftTimur

  I live in a residence where Internet is provided via cable. Once the computer is connected to the cable, launching a browser will trigger an authentication, I have a username and password to enter, then the internet will be connected. With a gateway (e.g. Wireless Cable Voice Gateway Model CBVG834G) and 2 cables, two PCs can connect to the Internet with my account at the same time. Now the question is, I don't like the cable, and would like to create a wifi hotspot. It seems realizable with the same gateway. According to the instruction on page 2-4 of the manual: Enter http://192.168.0.1 in the address field of your Internet browser. Log in to the gateway with either of the default user names, MSO or admin... However, while connecting to the Internet successfully via cable and the gateway (e.g. google works), opening 192.168.0.1 oddly gives me an error on the browser: Does anyone know what happened? Is it due to the authentication required by my residence? Is there any other way to build a hotspot of wifi? PS: My system is MAC OS

• Creating a pseudoterminal to make sudo happy

  - by larsks

  I need to automate the provisioning of a cloud instance (running Fedora 17) for which the following initial facts are true: I have ssh-key based access to a remote user (cloud) That user has password-free root access via sudo. Manual configuration is as simple as logging in and running sudo su - and having at it, but I would like to fully automate this process. The trick is that the system defaults to having the requiretty option enabled for sudo, which means that an attempt to do something like this: ssh remotehost sudo yum -y install puppet Will fail: sudo: sorry, you must have a tty to run sudo I am working around this right now by first pushing over a small Python script that will run a command on a pseudoterminal: import os import sys import errno import subprocess pid, master_fd = os.forkpty() if pid == 0: # child process: now that we're attached to a # pty, run the given command. os.execvp(sys.argv[1], sys.argv[1:]) else: while True: try: data = os.read(master_fd, 1024) except OSError, detail: if detail.errno == errno.EIO: break if not data: break sys.stdout.write(data) os.wait() Assuming that this is named pty, I can then run: ssh remotehost ./pty sudo yum -y install puppet This works fine, but I'm wondering if there are solutions already available that I haven't considered. I would normally think about expect, but it's not installed by default on this system. screen can do this in a pinch, but the best I came up with was: screen -dmS sudo somecommand ...which does work but eats the output. Are there any other tools available that will allocate a pseudoterminal for me that are going to be generally available?

• Backup script to FTP with timed subfolders

  - by Frederik Nielsen

  I want to make a backup script, that makes a .tar.gz of a folder I define, say fx /root/tekkit/world This .tar.gz file should then be uploaded to a FTP server, named by the time it was uploaded, for example: 07-10-2012-13-00.tar.gz How should such backup script be written? I already figured out the .tar.gz part - just need the naming and the uploading to FTP. I know that FTP is not the most secure way to do it, but as it is non-sensitive data, and FTP is the only option I have, it will do. Edit: I ended up with this script: #!/bin/bash # have some path predefined for backup unless one is provided as first argument BACKUP_DIR="/root/tekkit/world/" TMP_DIR="/tmp/tekkitbackup/" FINISH_DIR="/tmp/tekkitfinished/" # construct name for our archive TIME=$(date +%d-%m-%Y-%H-%M) if [ $1 ]; then BACKUP_DIR="$1" fi echo "Backing up dir ... $BACKUP_DIR" mkdir $TMP_DIR cp -R $BACKUP_DIR $TMP_DIR cd $FINISH_DIR tar czvfp tekkit-$TIME.tar.gz -C $TMP_DIR . # create upload script for lftp cat <<EOF> lftp.upload.script open server user user password lcd $FINISH_DIR mput tekkit-$TIME.tar.gz exit EOF # start backup using lftp and script we created; if all went well print simple message and clean up lftp -f lftp.upload.script && ( echo Upload successfull ; rm lftp.upload.script )

• Use Apache authentication + authorization to control access to Subversion subdirectories

  - by Stefan Lasiewski

  I have a single SVN repo at /var/svn/ with a few subdirectories. Staff must be able to access the top-level directory and all subdirectories within it, but I want to restrict access to subdirectories using alternate htpasswd files. This works for our Staff. <Location /> DAV svn SVNParentPath /var/svn AuthType Basic AuthBasicProvider ldap # mod_authnz_ldap AuthzLDAPAuthoritative off AuthLDAPURL "ldap.example.org:636/ou=people,ou=Unit,ou=Host,o=ldapsvc,dc=example,dc=org?uid?sub?(objectClass=PosixAccount)" AuthLDAPGroupAttribute memberUid AuthLDAPGroupAttributeIsDN off Require ldap-group cn=staff,ou=PosixGroup,ou=Unit,ou=Host,o=ldapsvc,dc=example,dc=org </Location> Now, I am trying to restrict access to a subdirectory with a separate htpasswd file, like this: <Location /customerA> DAV svn SVNParentPath /var/svn # mod_authn_file AuthType Basic AuthBasicProvider file AuthUserFile /usr/local/etc/apache22/htpasswd.customerA Require user customerA </Location> I can use Firefox and curl to browse to this folder fine: curl https://svn.example.org/customerA/ --user customerA:password But I cannot use check out this SVN repository: $ svn co https://svn.example.org/customerA/ svn: Repository moved permanently to 'https://svn.example.org/customerA/'; please relocate And on the server logs, I get this strange error: # httpd-access.log 192.168.19.13 - - [03/May/2010:16:40:00 -0700] "OPTIONS /customerA HTTP/1.1" 401 401 192.168.19.13 - customerA [03/May/2010:16:40:00 -0700] "OPTIONS /customerA HTTP/1.1" 301 244 # httpd-error.log [Mon May 03 16:40:00 2010] [error] [client 192.168.19.13] Could not fetch resource information.

• SQL Server 2008 Bring Database Online trying to open a file from a drive that doesn't exist

  - 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 domain keys and 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?

• Sudoers file allow sudo on specific file for active directory group

  - by tubaguy50035

  I have active directory sign in working on an Ubuntu 12.04 box. When the user signs in, I have a script that runs that needs sudo permission (since it modifies the samba config file). How would I specify this in my sudoer's file? I've tried: %DOMAIN\\AD+Programmers ALL=NOPASSWD: /usr/local/bin/createSambaShare.php I've found various resources on the internet stating that this is how it would be done, but I'm not sure that I have the first part right. What are they using as the DOMAIN? The workgroup or the realm? I use Samba + winbind for active directory integration. Here's my smb.conf: [global] security = ads netbios name = hostname realm = COMPANYNAME.COM password server = passwordserver workgroup = COMPANYNAME idmap uid = 1000-10000 idmap gid = 1000-10000 winbind separator = + winbind enum users = no winbind enum groups = no winbind use default domain = yes template homedir = /home/%D/%U template shell = /bin/bash client use spnego = yes domain master = no EDIT: The users that should have access to run that script are all part of the Programmers group which has an Active Directory Domain Services Folder of Company.com/Staff/Security Groups (not sure if that matters or not).

• Win7 Credential manager and accessing SQL Server from outside of the domain

  - by David Lively

  My SQL Server is set to use windows authentication. If I am connected to the domain directly from my Win7 Ultimate x64 machine, SQL Management Studio (SSMS) will let me authenticate with Windows authentication. However, if I am connected via the VPN (from a different machine that is not joined to the domain), it won't. If I start SSMS with the following command line: C:\Windows\system32>runas /netonly /user:domainname\username "C:\Program Files (x86)\Microsoft SQL...\ssms.exe" then connecting to the SQL Server (which is in the domain) with Windows Authentication works fine. I'd like to save these credentials so that I don't have to launch SSMS from the command line, or modify the shortcut. I know I can use the SysInternals ShellRunAs extension to do this, but I again have to enter my domain username and password each time, and shift+right-click to see that menu option. The Windows Credential Manager seems designed to solve this problem, and works for network shares. However, it doesn't seem to work for SSMS. Any suggestions? I've tried using the /savecred option with runas to create the necessary credentials, but that appears to be incompatible with the /netonly option. Running the above command line with the addition of /savecred just displays the runas help screen. Grrr. Argh.

• Understanding tcptraceroute versus http response

  - by kojiro

  I'm debugging a web server that has a very high wait time before responding. The server itself is quite fast and has no load, so I strongly suspect a network problem. Basically, I make a web request: wget -O/dev/null http://hostname/ --2013-10-18 11:03:08-- http://hostname/ Resolving hostname... 10.9.211.129 Connecting to hostname|10.9.211.129|:80... connected. HTTP request sent, awaiting response... 200 OK Length: unspecified [text/html] Saving to: ‘/dev/null’ 2013-10-18 11:04:11 (88.0 KB/s) - ‘/dev/null’ saved [13641] So you see it took about a minute to give me the page, but it does give it to me with a 200 response. So I try a tcptraceroute to see what's up: $ sudo tcptraceroute hostname 80 Password: Selected device en2, address 192.168.113.74, port 54699 for outgoing packets Tracing the path to hostname (10.9.211.129) on TCP port 80 (http), 30 hops max 1 192.168.113.1 0.842 ms 2.216 ms 2.130 ms 2 10.141.12.77 0.707 ms 0.767 ms 0.738 ms 3 10.141.12.33 1.227 ms 1.012 ms 1.120 ms 4 10.141.3.107 0.372 ms 0.305 ms 0.368 ms 5 12.112.4.41 6.688 ms 6.514 ms 6.467 ms 6 cr84.phlpa.ip.att.net (12.122.107.214) 19.892 ms 18.814 ms 15.804 ms 7 cr2.phlpa.ip.att.net (12.122.107.117) 17.554 ms 15.693 ms 16.122 ms 8 cr1.wswdc.ip.att.net (12.122.4.54) 15.838 ms 15.353 ms 15.511 ms 9 cr83.wswdc.ip.att.net (12.123.10.110) 17.451 ms 15.183 ms 16.198 ms 10 12.84.5.93 9.982 ms 9.817 ms 9.784 ms 11 12.84.5.94 14.587 ms 14.301 ms 14.238 ms 12 10.141.3.209 13.870 ms 13.845 ms 13.696 ms 13 * * * … 30 * * * I tried it again with 100 hops, just to be sure – the packets never get there. So how is it that the server does respond to requests via http, even after a minute? Shouldn't all requests just die? I'm not sure how to proceed debugging why this server is slow (as opposed to why it responds at all).

• Provisioning DELL servers using only linux tools

  - by Krist van Besien

  We have taken delivery of a bunch off Dell Poweredge Rack servers. Unfortunately when ordering it was neglegted to ask for dhcp to be enabled in the built in iDRAC controlers... So they are all stuck on the same IP address. Which means that I'll have to go to each of them individually and configure a new IP in the console... In the future I want to avoid that. Now Dell proposes to deliver the next batch with auto discovery enabled. As I understand this means that when the machine wakes up for the first time the iDRAC will request a DHCP address. The DHCP server then supposedly also provides a "provisioning" server, that provides it with a username and password, and a configuration to be applied. This would allow us to for example configure things like RAID automatically. However, I can't seem to find a way to set up such a provisioning server that does not involve setting up a windows machine. I want to use Linux tools exclusively. Is there a way to do this? I want to just rack servers, switch them on, and then do everything remotely. And that using only linux tools?

• How do I secure Sql Server 2008 R2

  - by Mark Tait

  I have both a dedicated and a VPS (from Fasthosts) virtual server - the web sites/applications I run on these, access Sql Server stored on the same web server. Until now, I have logged onto Sql Server on both the deidicated and VPS server, from Sql Server Management Studio - until I noticed in my server application logs, multiple attempts to logon to Sql Server using the 'sa' username, but failed password. So someone/bot is trying hard (repeatedly every couple of hours, for approx 20 attempts during each instance) to log on... so obviously I have to lock down access to Sql Sever remotely. What I have done is gone into Configuration Manager, and in Sql Server Network Configuration - Protocols for Sql2008 and also in Sql Native Client 10.0 Configuration - Client Protocols - I have diabled Named Pipes, TCP/IP (and VIA by default). I have left Shared Memory enabled. I also disabled in Sql Server Services, the Sql Server Browser. Now the only way I can manage the databases on these servers, is by logging on to them via Remote Desktop. Can anyone confirm if this is the correct way of stopping anyone maliciously logging on to Sql Server? (I'm not a DBA or security expert - and there are hundreds of articles advising all different ways - but I was hoping for the experts here to confirm, or otherwise, if what I've done is correct) Thank you, Mark

• Upgrading MySQL Connector/Net

  - by Todd Grover

  I am trying to publish a website with our hosting provider. I am getting error due to the fact that they only allow a medium trust and the MySQL Connector/Net that I am using requires reflection to work. Unfortunately, reflection is not allowed in a medium trust. After some research I found out that the newest version of the MySQL Connector/Net may solve this problem. Connector/Net 6.6 includes enhancements to partial trust support to allow hosting services to deploy applications without installing the Connector/Net library in the GAC. I am thinking that will solve my problem. So, I unistalled MySQL Connector/Net 6.4.4 and I installed MySQL Connector/Net 6.6.4. When I run the application in Visual Studio 2010 I get the error: ProviderIncompatibleException was unhandled by user code The message is An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct. InnerException is The provider did not return a ProviderManifestToken string. Everything works fine when I have Connector/Net 6.4.4 installed. I can access the database and perform Read/Write/Delete action against it. I have a reference to the following in the project: MySql.Data MySql.Data.Entity MySql.Web My connection string in Web.config <connectionStrings> <add name="AESSmartEntities" connectionString="server=ec2-xxx-xx-xxx-xx.compute-1.amazonaws.com; user=root; database=nunya; port=3306; password=xxxxxxx;" providerName="MySql.Data.MySqlClient" /> </connectionStrings> What might I be doing wrong? Do I need any additional setting(s) to work with version 6.6.4 that wasn't required in the older version 6.4.4?

• Windows 7 - system error 5 problem

  - by ianhobson

  My wife has just had a new computer for Christmas (with an upgrade from VISTA to Windows 7), and has joined the home network. We are using a mix of WindowsXP and Ubuntu boxes linked via a switch. We are all in the same workgroup. (No domain). Internet access, DHCP, and DNS server is an SME server that thinks it is domain controller (although we are not using a domain). I need to run a script to back up my wife's machine (venus). In the past the script creates a share on a machine with lots of space (leda), and then executes the line. PSEXEC \\venus -u admin -p adminpassword -c -f d:\Progs\snapshot.exe C: \\leda\Venus\C-drive.SNA With the wife's old XP machine, this would run the sysinternals utility, copy shapshot,exe to her machine and run it, which would then back up her C: drive to the share on leda. I cannot get this to work with Windows 7, nor can I link through to the C$ share on her machine. This gives me a permissions error (system error 5). The admin account is a full admin account. And yes - I do know the password. The ordinary shares on her machine work fine! I guess I'm missing something that Microsoft have built into Windows 7 - but what? The machine is running Windows 7 business, with windows firewall, AVG anti virus, and all the crap-ware you get with a new PC removed. Thanks

• Clarification for setting up SSH terminal access on Cisco IOS

  - by Matt Malesky

  I'm attempting to set up SSH on a Cisco 2811 and having some difficulties. The first step to this should be running crypto key generate rsa I seem to be missing this though: better#crypto key generate rsa ^ % Invalid input detected at '^' marker. better# Furthermore, the only available commands I have in the crypto key namespace are lock and unlock, which seem to indicate a locked keypair (for which I don't know the password): better#crypto key ? lock Lock a keypair. unlock Unlock a keypair. better#crypto key unlock ? rsa RSA keys better#crypto key unlock rsa %% Please enter the passphrase: %% Unlocking failed. . better# More or less, I'm asking what exactly this might mean, and if I actually do have certificates already here (used router)?

• What's the issue with this Samba setup?

  - by Dan Nestor

  I asked this on superuser, but I realized that may be the wrong place. I am duplicating the question here, I hope this is allowed. I am trying to share a directory through samba. In smb.conf I have the following: [global] workgroup = WORKGROUP security = user passdb backend = tdbsam netbios name = <hostname> [share_name] path = </path/to/share> writable = yes valid users = <username> <username>, the user in question, is the owner of directory /path/to/share. Permissions on the directory are 755. If I try to connect from another computer, the connection attempt is unsuccessful (I assume it's an authentication error, because it re-prompts me for the password). The client requires a domain name for authentication, I tried both WORKGROUP and the hostname/netbios name of the samba server. Samba logs on the server have no mention of the failed connection attempt. Firewall on the server is down. What am I doing wrong? Update: have since run smbpasswd -a <username> and now I am getting a clear error message, "not enough permissions to view contents of share".

• How to setup firewall to allow internet connection sharing via Wifi USB stick?

  - by hannanaha

  I have a Windows8 computer linked to the internet via an ethernet cable ("Ethernet" network connection). I have attached to it a DLink Wifi USB stick, and I'm trying to share the main PC's internet connection with my Android phone via a local wifi network. I am using the following batch file to set up this network: netsh wlan set hostednetwork mode=allow ssid=MyWifiName key=password keyUsage=persistent netsh wlan start hostednetwork After I run this script, I can see a new network connection appear in "Control Panel\Network and Internet\Network Connections" named "Local Area Connection *12", and I can see "MyWifiName" on the Android phone. The device name for this connection on the PC is "Microsoft Hosted Network Virtual Adapter". I also set up the "Ethernet" connection to share Internet with "Local Area Connection *12". However, the Android phone usually doesn't manage to obtain an IP from the wireless network, and when it does, there still seems to be no connectivity to the internet. When I turn off the Windows Firewall completely, or even just for "Local Area Connection *12", the Android connection is perfect. My questions are: How should I set up the Windows firewall to allow the phone to connect properly? Is there a specific rule I need to add to the Windows firewall advanced settings? [Note: the above method worked great in Windows 7, without any specific tinkering with the firewall]. Is it safe to turn off the firewall specifically for the "Local Area Connection *12" (the wifi connection) if the main Ethernet connection is still protected by the firewall? Thanks in advance.

• Set proper rights for sshfs mountpoint so it can be shared with samba

  - by CS01

  I have a domain hoster that provides access via SSH. My platforms are: Gentoo 2.6.36-r5 Windows (XP/Vista/7) I work on my Windows, I use Gentoo to do all the magic Windows can't do. Therefore I use sshfs to mount the remote public directory for my domain to /mnt/mydomain.com. Authentication is done via keys, so lazy me don't have to type in my password every now and then. Since I do my coding on Windows, and I don't want to upload/download the changed files all the time, I want to access this /mnt/mydomain.com via a samba share. So I shared /mnt in samba, all mounts except mydomain.com is listed on my Windows Explorer. My theories are: sshfs does not set the mountpoint uid/gid to something that samba expects samba does not know that it has to include the uid/gid that /mnt/mydomain.com has been set. All above is wrong, and I don't know. Here are configs and output from console, need anything else just let me know. Also no errors or warnings that I take notice of being relevant to this issue, but I might be wrong. gentoo ~ # ls -lah /mnt total 20K drwxr-xr-x 9 root root 4.0K Mar 26 16:15 . drwxr-xr-x 18 root root 4.0K Mar 26 2011 .. -rw-r--r-- 1 root root 0 Feb 1 16:12 .keep drwxr-xr-x 1 root root 0 Mar 18 12:09 buffer drwxr-s--x 1 68591 68591 4.0K Feb 16 15:43 mydomain.com drwx------ 2 root root 4.0K Feb 1 16:12 cdrom drwx------ 2 root root 4.0K Feb 1 16:12 floppy drwxr-xr-x 1 root root 0 Sep 1 2009 services drwxr-xr-x 1 root root 0 Feb 10 15:08 www /etc/samba/smb.conf [mnt] comment = Mount points writable = yes writeable = yes browseable = yes browsable = yes path = /mnt /etc/fstab sshfs#[email protected]:/home/to/pub/dir/ /mnt/mydomain.com/ fuse comment=sshfs,noauto,users,exec,uid=0,gid=0,allow_other,reconnect,follow_symlinks,transform_symlinks,idmap=none,SSHOPT=HostBasedAuthentication 0 0 For an easier read: [email protected] /home/to/pub/dir/ /mnt/mydomain.com/ options: comment=sshfs noauto users exec uid=0 gid=0 allow_other reconnect follow_symlinks transform_symlinks idmap=none SSHOPT=HostBasedAuthentication Help!

• Postfix misconfigured? 550 Sender rejected from recieving server

We have tested it with one other recipient and it worked, so this problem might be completely unrelated to our settings, but related to the recipient. Still, with this question, I want to make sure we're not making an obvious misconfiguration on our side.

• IIS 6 Windows Authentication in ASP.Net app fails

  - by Kjensen

  I am trying to install an ASP.Net app on an IIS6 webserver. The site requires the user to authenticate with windows, and this works on several other apps on the same server. In IIS I have enabled anonymous access and windows authentication. In web.config, authentication is set to: <authentication mode="Windows"/> and authorization...: <authorization> <allow roles="Users"/> <deny users="*"/> </authorization> Ie. allow all users in role "Users" and deny everybody else. This is the approach that is working with several other apps on the same server. If I run the site, I am prompted for username and password. If I remove the line: <deny users="*"/> I can access the site and everything works - but the user credentials are not passed to the site (Page.User.Identity.Name returns a blank string in ASP.Net). The site has identical (inherited) file permissions as other working sites on the server. The only difference in authentication/authorization between this site and the other working sites is, that this runs Asp.Net 4 (but there are other working asp.net 4 sites on the server as well). What am I missing here? Where should I look?

• Windows 8 Pro Homegroup Not Allowing Access to Shared Files

  - by Jack Herr

  I have two pc's and a laptop. With all three running Windows 7, homegroup worked perfectly, with all computers able to access the files on the others exactly as one would expect. I installed Windows 8 Pro, which I downloaded recently from the MSDN website, on the laptop. From the info on the MSDN website, I believe the version downloaded is the official release version, not a release candidate. The install preserved all settings, apps, and files. I cannot connect to the homegroup from the laptop. Well, not exactly. I joined the homegroup during the install, and later left and rejoined, that was advertised as being offered by one of the pc's (not sure why that one was picked and not the other or both). This homegroup appears in my "computer" folder in the file explorer, offering files from that pc. But it excludes documents (only the music, pix, videos, and playlists folders on the one computer appear). I can actually access those files from the laptop. But the Homegroup folder, which actually shows all the computers by account and computer name and includes documents from both computers, does not open those folders when clicked. The computers listed by name in the Network folder give me a login that doesn't work. It asks for a username and password, no combinations of which work. Further, the following error message appears before the login is even attempted: "The system cannot contact a domain controller to service the authentication request. Please try again later." The two windows 7 pc's continue to share all files, including documents, seemlessly. I can also get to the laptop shared files, which I shared during setup, from either pc. Any ideas?

• Are there any Graphical PowerShell tools?

  - by Dai

  As a developer for the .NET platform, I like to "explore" a platform, framework or API by browsing through the API documentation which explains what everything is - everything is covered and when I use tools like Reflector or Object Browser then I get to know for certain what I'm working with. When I'm writing my own software I can use tools like the Object Test Bench to explore and work with my classes directly. I'm looking for something similar, but for PowerShell - and ones that avoid text-mode. PowerShell is nice, and there are a lot of cool "discoverability"-things it has, such as the "Verb-Noun" syntax, however when I'm working with Exchange Server, for example, I wanted to get a list of AD Permissions on a Receive Connector and I got this list: [PS] C:\Windows\system32>Get-ADPermission "Client SVR6" -User "NT AUTHORITY\Authenticated Users" | fl User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : True AccessRights : {ReadProperty} IsInherited : True Properties : {ms-Exch-Availability-User-Password} ChildObjectTypes : InheritedObjectType : ms-Exch-Availability-Address-Space InheritanceType : Descendents [PS] C:\Windows\system32> Note how the first few entries contain identical text - there's no way to tell them apart easily. But if there was a GUI presumably it would let me drill-down into the differences better. Are there any tools that do this?
