• Installing Apache MPM Worker on Centos 5.5

  - by mrmartinblue

  I have a CentOS 5.5. server and am trying to switch from MPM Prefork to MPM worker. I have the standard yum httpd packages installed currently and from my reading I did the following: Uncomment the httpd.worker line in the /etc/sysconfig/httpd file. I also made sure that the httpd.worker file exists in the /usr/sbin/ directory. I also made sure that httpd service is stopped before making the above change. Ensured PHP was disabled for Apache. I'm fine with this and will use FastCGI to handle PHP files once I get the MPM worker up and running. Restart the httpd service, everything starts fine. Do a # httpd -V The console tells me it's still using prefork. If I do a # vi /etc/init.d/httpd the httpd.worker line is still commented out. I've tried changed this as well to no difference. Any suggestions? Things to look at? My application requires the worker MPM so the only choice I can think of is to go with ubuntu or another flavor that has the dedicated apache2-mpm-worker package. Is there something similar in the yum repos somewhere? Thanks in advance!

• How can I connect my Xbox to my Mac on my network

  - by codecowboy

  I have a wireless router/modem (Router 1) in my living room. This is connected to the internet (cable). Wireless is disabled as the router has a terrible wireless range. My Xbox is connected via ethernet to Router 1. Another LAN output from Router 1 connects to a powerline adapter. Router 1 acts as a DHCP server on 192.168.0.x and has the IP 192.168.0.1 In a second room I have Router 2. This has the powerline feed from Router 1 going into the WAN socket. This router runs the Tomato Firmware and acts as a wireless router for the rest of the house using the IP range 192.168.1.x. Router 2 IP is 192.168.1.1. My Mac is connected to Router 2 using a LAN cable and has the IP 192.168.0.133. Several mobile devices need wireless access. I want an ethernet connection to my Mac, not wireless. I should be able to use software like Connect360 to share media from my Mac to the XBox but the XBox does not see my Mac. I can ping 192.168.0.1 from the Mac. Is this possible using my current setup? If so, how?

• Windows authentication to SQL Server via IIS and PHP

  - by Jeff

  We're running a PHP 5.4 application on Server 2008 R2. We would like to connect to a SQL Server 2008 database, on a separate server, using Windows authentication (must be Windows authentication--the DB admins won't let us connect any other way). I have downloaded the SQL Server drivers for PHP and installed them. IIS is configured for Windows authentication, and anonymous authentication has been disabled. $_SERVER['AUTH_USER'] reports our currently logged on Windows account. In php.ini, we have set fastcgi.impersonate = 1. When we setup a connection using the following code from Microsoft: $serverName = "sqlserver\sqlserver"; $connectionInfo = array( "Database"=>"some_db"); /* Connect using Windows Authentication. */ $conn = sqlsrv_connect( $serverName, $connectionInfo); if( $conn === false ) { echo "Unable to connect.</br>"; die( print_r( sqlsrv_errors(), true)); } We are presented with the following error message: Unable to connect. Array ( [0] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. [message] => [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. ) Is it possible to connect to SQL Server 2008 via PHP using Windows authentication? Are there any additional required settings we need to make on IIS, SQL Server, or any other component (like a domain controller)?

• Why won't my computer go to sleep automatically?

  - by Django Reinhardt

  Windows 8 is set to sleep after 30 mins, and it used to work, but recently it's started refusing to sleep. (I can still manually ask it to go to sleep without any issue.) I was having issues a while ago, but it was with my network adapter. That's since been disabled, so it's definitely not that: I've checked to see what devices are able to wake up my machine, but it only appears to be my mouse: Which is odd, because I haven't recently changed my mouse, and more confusing still: The monitor does go to sleep just fine. If it was actually the mouse keeping my system awake, I'm pretty sure the monitor wouldn't go to sleep. I've checked my Wake Timers, and nothing: I've also checked my existing requests... UPDATE: I found something. What to do with it, I don't know... Note: Even when /requests says that there's "NONE" under every category, my machine still won't sleep(!). In short: How can I tell what's preventing my computer from Sleeping? UPDATE: Ok, so I now have a few more pieces of the puzzle. I came back to my computer and it was ASLEEP! Lawks! It seems that the only times it doesn't sleep is if VLC Player is open, even if a video isn't actually playing. UPDATE UPDATE: Ok, so it won't sleep sometimes when VLC Player ISN'T running, either. Bah!

• Can I get all active directory passwords in clear text using reversible encryption?

  - by christian123

  EDIT: Can anybody actually answer the question? Thanks, I don't need no audit trail, I WILL know all the passwords and users can't change them and I will continue to do so. This is not for hacking! We recently migrated away from a old and rusty Linux/Samba domain to an active directory. We had a custom little interface to manage accounts there. It always stored the passwords of all users and all service accounts in cleartext in a secure location (Of course, many of you will certainly not think of this a being secure, but without real exploits nobody could read that) and disabled password changing on the samba domain controller. In addition, no user can ever select his own passwords, we create them using pwgen. We don't change them every 40 days or so, but only every 2 years to reward employees for really learning them and NOT writing them down. We need the passwords to e.g. go into user accounts and modify settings that are too complicated for group policies or to help users. These might certainly be controversial policies, but I want to continue them on AD. Now I save new accounts and their PWGEN-generated (pwgen creates nice sounding random words with nice amounts of vowels, consonants and numbers) manually into the old text-file that the old scripts used to maintain automatically. How can I get this functionality back in AD? I see that there is "reversible encryption" in AD accounts, probably for challenge response authentication systems that need the cleartext password stored on the server. Is there a script that displays all these passwords? That would be great. (Again: I trust my DC not to be compromised.) Or can I have a plugin into AD users&computers that gets a notification of every new password and stores it into a file? On clients that is possible with GINA-dlls, they can get notified about passwords and get the cleartext.

• 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.

• Anonymous access to SMB share hosted on Server 2008 R2 Enterprise

  - by bwerks

  Hi all, First off, I have read through this post and a whole slew of non-SF posts which seem to address the same or a similar problem, however I was still unable to fix my problem. I've got three machines in this situation: a domain-joined server that runs Server 2008 R2 Enterprise ("share server") a domain-joined workstation running XP Pro SP3 ("test server") a domain-unjoined test server running Server 2003 R2 SP2 ("workstation") The share server is exposing a share on the network that the test server must access--it's a Source/Symbol Server share for our debugging purposes. I believe visual studio simply accesses the the share with its own credentials in this case, meaning that the share must be accessible anonymously since the test server isn't joined to the domain and there's no opportunity to supply domain authentication. I've attempted a lot of things to avoid the authentication window when accessing the share: I've enabled the Guest account on the share server and given Guest full sharing/NTFS permissions for the share. I've given ANONYMOUS LOGON full sharing/NTFS permissions for the share. I've added my share to “Network Access: Shares that can be accessed anonymously” in LSP. I've disabled “Network access: Restrict anonymous access to Named Pipes and Shares” in LSP. I've enabled “Network access: Let Everyone permissions apply to anonymous users” in LSP. Added ANONYMOUS LOGON to “Access this computer from the network” in LSP. Added the Guest account to “Access this computer from the network” in LSP. Attempted to provision the share using the Share and Storage Management MMC snap-in. Unfortunately when I attempt to access the share from the test server, I still see the prompt and I'm forced to enter "Guest" manually. I also tried this workflow using the local administrator account on a workstation, and the same thing happens both with and without XP Simple File Sharing enabled. Any idea why I'm getting these results, or what I should have done differently?

• 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

• Windows Server 2008 R2 Finding Hidden files that are causing drive to fill up

  - by Xaxum

  What is the best way to find out what files are sucking up so much space? My Windows directory lists its size as 15 GB but when I run a powershell script against it, it shows 40 GB. It seems 40 GB is about right because if I use that 40 GB and add it to the rest of my folders on C I get the 45 GB that is in use. I checked volume shadow copy and that is disabled and there are no volume shadow files listed. My page file is limited to 3 GB. How can I find out what files are taking 25 GB of space? Final Results: We ended up disabling UAC and then the Properties showed the true file size of the Windows folder, as shown in powershell script. This allowed us to drill down to the folder that had the issues... In our case it was in C:\Windows\System32\config\systemprofile\AppData\Local\VMware\VDM there were several large dump files, these were the mysterious unknown files in WinDirStat. It turns out our nessus scan is crashing a view service for a couple seconds so it creates a large dump file. So we will try this.. https://discussions.nessus.org/thread/5212

• Is there a free PDF printer / distiller that creates signable documents?

  - by Coderer

  I've used various methods (mentioned elsewhere on this site) to create PDFs, using a printer driver or converting from PostScript, etc. The common problem is that if I open any of the output files in the newer versions of Adobe Reader, there's an option to "Place Signature" but it's greyed out, or gives an error message that the feature has been disabled for this document. As far as I can tell, there's an option set somewhere in the document metadata that tells Reader "allow the user to sign this document", or don't. None of the free/open source tools that have been been linked to in other SU posts have had this listed as an option (though to be fair I haven't actually downloaded and tried all of them). Is there a tool that does this? Can I just poke a bit with a hex editor somewhere to turn on this functionality? I can sometimes get access to Acrobat Professional to turn on this option, but doing it for every desired case would be more work than I care to do. The current workaround for single-page documents is: Print the document to PDF (possibly via postscript) Open a single-page blank PDF with the "signable" bit turned on in Reader create a custom "stamp" using the Reader markup tools, by importing the printed-to document "stamp" an image of the printed document on the blank page, hoping to get it centered about right place a signature over the document-but-not-really you just stamped This obviously does not scale well at all. It would be much better if I could: Print the document to PDF Drag the document to a simple shortcut / tool / whatever Open the document in Reader Place a signature in the document ETA: Sorry, maybe I should have been clearer -- I'm talking about the certificate-based digital signing available in Adobe Reader, not adding a virtual ink signature. Also, any solution really would have to be available offline.

• mount error 5 = Input/output error

  - by alharaka

  I am running out of ideas. After a long period of testing this morning, I cannot seem to get this to work, and I have no idea why. I want to mount a Windows SMB/CIFS share with a Debian 5.0.4 VM, and it is not cooperating. This the command I am using. debianvm:/home/me# whoami root debianvm:/home/me# smbclient --version Version 3.2.5 debianvm:/home/me# mount -t cifs //hostname.domain.tld/share /mnt/hostname.domain.tld/share --verbose -o user=SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD/username mount.cifs kernel mount options: unc=//hostname.domain.tld\share,ip=10.212.15.53,domain=SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD,ver=1,rw,user=username,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,pass=*********mount error 5 = Input/output error Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) debianvm:/home/me# The word on the nets has not been very specific, and unfortunately it is almost always environment-specific. I receive no authentication errors. I have tried mount -t smbfs and mount -t cifs, along with smbmount and such. I get the same error before. I doubt it is a problem with DNS resolution, because logging shows the correct IP address. dmesg | tail -f no longer shows authentication errors when I format the domain and username accordingly. I have played a little with iocharset=utf8, file_mode, and dir_mode as described here. That did not help either. I have also tried ntlm and ntlmv2 assuming it might be a minimum auth method problem, but not forcing sec=ntlmv2 it can still authenticate without errors anymore. smbclient -L hostname.domain.tld -W SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD -U username correctly lists all the shares and shows it as the following. Domain=[SUBADDOMAIN] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager] Sharename Type Comment --------- ---- ------- IPC$ IPC Remote IPC ETC$ Disk Remote Administration C$ Disk Remote Administration Share Disk Connection to hostname.domain.tld failed (Error NT_STATUS_CONNECTION_REFUSED) NetBIOS over TCP disabled -- no workgroup available I find the last line intriguing/alarming. Does anyone have any pointers!? Maybe I misread the effin manual.

• What kernel modules are required for wi-fi to work?

  - by Leonid Shevtsov

  My custom-built 2.6.32 kernel cannot connect to any WPA-protected network. The kernel includes (probably?) everything that should be needed for wifi, including IPv4 network support (IPv6 is disabled), the ath5k wireless driver (which is used in the generic Ubuntu 2.6.31 kernel) and all crypto APIs. The card is being detected, however, iwlist scan returns wlan0 Failed to read scan data : Network is down and network-manager log says <info> (wlan0): driver supports SSID scans (scan_capa 0x01). <info> (wlan0): new 802.11 WiFi device (driver: 'ath5k') <info> (wlan0): exported as /org/freedesktop/NetworkManager/Devices/1 <info> (wlan0): now managed <info> (wlan0): device state change: 1 -> 2 (reason 2) <info> (wlan0): bringing up device. <info> (wlan0): preparing device. <info> (wlan0): deactivating device (reason: 2). supplicant_interface_acquire: assertion `mgr_state == NM_SUPPLICANT_MANAGER_STATE_IDLE' failed <info> modem-manager is now available <WARN> default_adapter_cb(): bluez error getting default adapter: The name org.bluez was not provided by any .service files <info> Trying to start the supplicant... <info> (wlan0): supplicant manager state: down -> idle <info> (wlan0): device state change: 2 -> 3 (reason 0) <WARN> nm_supplicant_interface_add_cb(): Unexpected supplicant error getting interface: wpa_supplicant couldn't grab this interface.

• Can I use a Windows Server 2003 Domain Controller but my home router for DNS?

  - by NetworkingWannabie

  Hi All Probably easiest to start with a description of my current setup, which works (oh, and this is a home setup not an office or anything): I have an ADSL modem with a static IP address (192.168.128.1), and its DHCP capability is disabled. I have a permanently powered up Windows Server 2003 machine with a fixed IP (192.168.128.2) which provides my domain controller, dhcp, and dns. The default gateway for everything is my ADSL modem everything is setup to use the WS2003 machine as the primary DNS with the ADSL modem as Secondary DNS just in case the server goes down (everything includes the server itself). Lastly, just in case it's relevant, I have my DHCP leases set to infinite (or whatever the right term is). Everything is pretty hunky dory. Except, that is, for the fact that my server is ALWAYS on, and it isn't always used, so I'm burning juice that I don't need to - my server burns around 120W which isn't immense but isn't irrelevant either, so I'd like to put it into a stand-by state when it isn't being used (the more standby the better) and then get the clients to wake it up. Am I correct in assuming that this won't work at the moment - A given client would need an IP address to wake the machine up, and it needs to machine to be awake to get an IP - catch 22? Assuming I'm correct, can I move to using my router (which is always on) for DHCP? What impact will this have on DC and DNS? Alternatively, does anyone have a better way for me to achieve this? Can I get the server to wake up when it sees clients look for a DHCP server, etc? Wow, that came out longer than expected! Thanks for your help.

• Troubleshooting wireless client-bridged networks between two DD-WRT routers?

  - by KronoS

  I recently purchased a Buffalo N600 wireless router which came with DD-WRT pre-installed. I want to take my old wireless router a Linksys WRT54GL, also with DD-WRT pre-installed, and use it as a wireless bridge for my HTPC and Blu-Ray Player in the other room. I other words, I'm trying to connect to WIRED networks via the wireless on the routers. I followed eactly the instruction from DD-WRT's manual for 'Client Bridged' however I'm still not able to connect to two routers correctly, when the encryption is enabled (WPA2-Personal Mixed) however I am able to connect the two routers when there is NO encryption. I've checked, double checked, and triple checked that EVERYTHING is the same on BOTH routers: Routers 1 & 2 Encryption: WPA2-Personal Mixed Wireless Mode: G-Only Wireless Channel: 6 Subnet Mask: 255.255.255.0 Subnet: 192.168.1.0/254 SSID: Krono$ Primary Router #1 (Buffalo N600) IP Address: 192.168.1.1 Firewall: Enables w/ defaults DCHP: Enabled as DHCP Server Secondary Router #2 (Linksys WRT54GL) IP Address: 192.168.1.2 Firewall: Disabled as per DD-WRT instructions I'm looking for any configurations that I may have missed, or settings that may need to happen in order for this work.

• SSH connection problem - allowed from LAN but not WAN

  - by Kerem Ulutas

  I tried to setup my Arch Linux installation to be an SSH host, but here is the thing: I can ssh localhost, it fails to login via public key and asks for username and password, but still able to login. When I try ssh my_wan_ip it gives ssh_exchange_identification: Connection closed by remote host error. I've read all topics about this error and none helped me. By the way, just confirmed, it gives ssh: connect to host my_dyndns_hostname port 22: Connection refused from another machine (outside of my network, it has different wan ip). I have sshd: ALL in "hosts.allow", ALL:ALL in "hosts.deny". I am able to connect to my own pc via ssh, ping my own pc, but my ssh setup seems to be the problem, it gives that annoying error when I try to ssh from wan. /etc/ssh/ssh_config /etc/ssh/sshd_config And finally, here is the debug output for both sshd and ssh: (i ran ssh command and i took output to sshd debug after that): sshd debug ssh debug I can edit my question according to your needs. Just ask for any more information needed. BTW I have no iptables running. I have one cable dsl modem connected to a asus wl-330gE wireless access point, they both have their firewall disabled. I configured NAT so port 22 is directed to the pc I'm having this trouble. Any help appreciated, thanks..

• What are the requirements for Windows Remote Assistance over Teredo?

  - by Jens

  I try to get the Windows 7 (or Vista) remote assistance feature to work, without using UPnP on the novices computer. After enabling Teredo on the expert's computer (that is in a corporate network, and therefore has teredo disabled by default), I tried to connect to the novice both using Easy Connect and the invitation file with no success. My triubleshooting included the following (so far). A connection to the novice from my home pc was successful, hinting at a misconfiguration on the experts side. Both computers have a "qualified" connection to the Teredo Server. Both computers have a valid Teredo IP, access to the Global_ PNRP cloud and can resolve names registered with PNRP on the other computer. The expert can resolve the PNRP Id automatically generated with an Easy Connect help request Both computers can ping the other's PNRP name. Both computers can ping the other's Teredo IP Address using ping -6 Now, I am a little stumped. I expected Remote Assistance to work at this point, since my corporate firewall has no Teredo filtering. What could RA cause not to work in this setting? Thanks in advance!

• Distortion problem with Creative audio equalizer

  - by e-t172

  Hi, I have a problem with the Creative Console EQ, I don't know if it's fixable or not (is the EQ software or hardware on these cards?). Basically, I have enormous distortion with certain sounds in the 30 - 125 hz range. When this happens I get some sort of "frrzzzz" (sorry, I'm french and don't really know the correct english word for that) on top of the original sound. I have a Sound Blaster Audigy SE. I'm using the Daniel_K drivers, on Windows 7 Profesionnal x64. All the effects are disabled except EQ. Steps to reproduce Put the card in 24bit/96khz mode. The problem is also present with 16bit/48khz but seems to be less audible. In the Creative Console, use the following EQ: (full size) Play this sound at a reasonably high volume. You should hear distortion on the two "booms". Especially the second one. Disable Creative EQ. Play the sound in an application with an integrated EQ (e.g. foobar2000, ffdshow) using the same EQ parameters. There is no distortion. Conclusion: the Creative EQ is broken. Is anyone having the same problem? I'm also interested in the results with other Creative cards or even other brands soundcards with a similar EQ feature.

• can't ssh from mac to windows (running ssh server on cygwin)

  - by Denise

  I set up an ssh server on a fresh windows 7 machine using the latest version of cygwin. Disabled the firewall. I can ssh into it from itself, from a different windows box (using winssh), and from a linux vm. In spite of that, I tried to ssh in from two different macs, and neither would let me! This is the debug output: OpenSSH_5.1p1, OpenSSL 0.9.7l 28 Sep 2006 debug1: Reading configuration data /etc/ssh_config debug1: Connecting to 3dbuild [172.18.4.219] port 22. debug1: Connection established. debug1: identity file /Users/Denise/.ssh/identity type -1 debug1: identity file /Users/Denise/.ssh/id_rsa type 1 debug1: identity file /Users/Denise/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.5 debug1: match: OpenSSH_5.5 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.1 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-cbc hmac-md5 none debug1: kex: client->server aes128-cbc hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY debug1: Host '3dbuild' is known and matches the RSA host key. debug1: Found key in /Users/Denise/.ssh/known_hosts:43 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,password,keyboard-interactive debug1: Next authentication method: publickey debug1: Trying private key: /Users/Denise/.ssh/identity debug1: Offering public key: /Users/Denise/.ssh/id_rsa Connection closed by [ip] It shows the same output, and fails at the same place, whether I have put my public key on the ssh server or not. Any help would be appreciated-- hopefully someone has run into this before?

• 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!
