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

  - by MariusPontmercy

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

• RHEL hangs after starting virt-who succesfully

  - by Nick

  Idea #1: Is there a way to REPAIR an RHEL 6.2 installation? During the start-up procedure, after a recent forced reboot, my Linux machine (RHEL 6.2) hangs right after successfully starting virt-who. I can use login screens (Alt + F2/F3...) in text mode. I am clueless -- how can I find out what is the next step in the startup sequence? That step is most likely what is causing it to hang. These are the last lines saved to /var/log/boot.log: Starting RPC idmapd: [60G[[0;32m OK [0;39m] Starting cups: [60G[[0;32m OK [0;39m] Starting acpi daemon: [60G[[0;32m OK [0;39m] Starting HAL daemon: [60G[[0;32m OK [0;39m] Starting PC/SC smart card daemon (pcscd): [60G[[0;32m OK [0;39m] Retrigger failed udev events[60G[[0;32m OK [0;39m] Loading autofs4: [60G[[0;32m OK [0;39m] Starting automount: [60G[[0;32m OK [0;39m] Enabling Bluetooth devices: Starting sshd: [60G[[0;32m OK [0;39m] Starting ntpd: [60G[[0;32m OK [0;39m] Starting mysqld: [60G[[0;32m OK [0;39m] Starting postfix: [60G[[0;32m OK [0;39m] Starting abrt daemon: [60G[[0;32m OK [0;39m] Starting ksm: [60G[[0;32m OK [0;39m] Starting ksmtuned: [60G[[0;32m OK [0;39m] Starting Qpid AMQP daemon: [60G[[0;32m OK [0;39m] Starting crond: [60G[[0;32m OK [0;39m] Starting atd: [60G[[0;32m OK [0;39m] Starting libvirtd daemon: [60G[[0;32m OK [0;39m] Starting rhsmcertd 240 1440[60G[[0;32m OK [0;39m] Starting virt-who: [60G[[0;32m OK [0;39m]

• Remote RIB iLO on Proliant via RIBCL

  - by Wudang

  I'm trying to automate a process for our Ops. The process requires that some windows servers running on blades are shut down, left down for a few hours, the restarted when some other processes complete. This is done by an op logging on to each blade's iLO web interface to stop and start. I've been trying to automate this with HP's cpqlocfg program with partial success. I can issue the GET_POWER, GET_USER_INFO, etc commands but SET_HOST_POWER fails in a specific way. Using the cpqlocfg GET_EVENTLOG command I can see the events XML login and the power comand being issued from the iLO interface but then nothing happens. Some hints from googling suggest ACPI isn't configured properly but I can't find any hits on how to verify this. Am I even using the right command? There's also a few other options like PRESS_PWR_BUTTON etc. Problem is I have nowhere to test this, all I can do at the moment is give a script to ops and ask them to try it as 4am on a Sunday when they try the proc. The shutdown is trivial as I can use the windows "shutdown" command, it's the power on that I need help on. Anyone done this? I'd tag this "rib ribcl ilo" but lack the rep points, sorry.

• Xenserver 6.2 cannot send alert using gmail smtp

  - by Crimson

  I'm using Xenserver 6.2 and configured ssmtp.conf an mail_alert.conf in order to receive alerts through email. I followed the instructions on http://support.citrix.com/servlet/KbServlet/download/34969-102-706058/reference.pdf document. I'm using gmail smtp to send the emails. When i try: [root@xen /]# ssmtp [email protected] from the command line and try to send the email, no problem. It is right on the way. But when i set some VM to generate alerts, alerts are generated. I see in XenCenter but emailing is not working. I see this in /var/log/maillog file: May 27 16:17:09 xen sSMTP[30880]: Server didn't like our AUTH LOGIN (530 5.7.0 Must issue a STARTTLS command first. 18sm34990758wju.15 - gsmtp) From command line every thing works fine.

• Dovecot install: what does this error mean?

So the dovecot.conf file might not be correct, but there is no good source I have found yet for making dovecot install correctly. Can anyone tell me what the error above means? The terminal does not give any message as to start OK or FAIL. When I issue the service dovecot start command, it says: Starting Dovecot Imap: and nothing more.

• Apache Bad Request "Size of a request header field exceeds server limit" with Kerberos SSO

  - by Aurelin

  I'm setting up an SSO for Active Directory users through a website that runs on an Apache (Apache2 on SLES 11.1), and when testing with Firefox it all works fine. But when I try to open the website in Internet Explorer 8 (Windows 7), all I get is "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Authorization: Negotiate [ultra long string]" My vhost.cfg looks like this: <VirtualHost hostname:443> LimitRequestFieldSize 32760 LimitRequestLine 32760 LogLevel debug <Directory "/data/pwtool/sec-data/adbauth"> AuthName "Please login with your AD-credentials (Windows Account)" AuthType Kerberos KrbMethodNegotiate on KrbAuthRealms REALM.TLD KrbServiceName HTTP/hostname Krb5Keytab /data/pwtool/conf/http_hostname.krb5.keytab KrbMethodK5Passwd on KrbLocalUserMapping on Order allow,deny Allow from all </Directory> <Directory "/data/pwtool/sec-data/adbauth"> Require valid-user </Directory> SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile /etc/apache2/ssl.crt/hostname-server.crt SSLCertificateKeyFile /etc/apache2/ssl.key/hostname-server.key </VirtualHost> I also made sure that the cookies are deleted and tried several smaller values for LimitRequestFieldSize and LimitRequestLine. Another thing that seems weird to me is that even with LogLevel debug I won't get any logs about this. The log's last line is ssl_engine_kernel.c(1879): OpenSSL: Write: SSL negotiation finished successfully Does anyone have an idea about that?

• Vista Power Management GPO

  - by Matt

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

• Mounting a TrueCrypt volume over FTP

  - by Maxim Zaslavsky

  Is it possible to mount a TrueCrypt volume file over FTP? Here's how TrueCrypt works with a local file: User inputs path to volume file, enters password TrueCrypt verifies that the password is correct (probably by decrypting the very first part of the volume file?) TrueCrypt reads the directory listing from the volume file and mounts the volume. However, in this step, TrueCrypt does NOT process the whole volume file. The user browses the directory listing and opens a file. TrueCrypt reads only the part of the volume file that contains the file the user wants, and then decrypts it. Once again, TrueCrypt doesn't process the whole volume file - it only reads part of it. The user edits part of the file and saves it. TrueCrypt encrypts the change and edits the volume file. I'm pretty sure it should be possible to mount a volume over FTP, without undermining security and without having to transfer the whole volume file just to read one small part of the volume. Here's how I imagine it: User inputs FTP path to volume file, enters FTP login information, enters password to volume TrueCrypt downloads the very first part of the volume file and verifies that the password is correct TrueCrypt downloads the part of the volume file that contains the directory listing - the data is sent encrypted over FTP and is decrypted locally. The user browses the directory listing and opens a file. TrueCrypt downloads only the part of the volume file that contains the file the user wants, and then decrypts it locally. The user edits part of the file and saves it. TrueCrypt encrypts the change and edits the volume file over FTP, transferring encrypted data only. Is such a feature available?

• Two-way Trust relationship between Samba 3 and AD 2008 R2

  - by Romain

  Did somebody already make a two-way trust relationship between Samba 3 and AD ? I've got Samba 3.5 domain (ES02) controller and AD 2008 R2 domain (ES01) controller. Trust domain seems to be ok: Trusted domains list: ES01 S-1-5-21-1816646249-803782145-3669927669 Trusting domains list: ES01 S-1-5-21-1816646249-803782145-3669927669 I can login AD domain workstation with a Samba user account and access to AD domain workstation shares from Samba workstation with Samba user account. BUT, when I try to access to Samba domain workstation shares from AD domain workstation with AD account (test), I've got this: [2012/12/16 23:00:26.146090, 5] auth/auth.c:268(check_ntlm_password) check_ntlm_password: winbind authentication for user [test] FAILED with error NT_STATUS_NO_SUCH_USER [2012/12/16 23:00:26.146123, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [test] - [test] FAILED with error NT_STATUS_NO_SUCH_USER When I try to access samba share with the Administrator account that I create on both side with same password, I've got this: [2012/12/16 22:57:22.701841, 1] rpc_server/srv_pipe_hnd.c:1602(serverinfo_to_SamInfo_base) _netr_LogonSamLogon: user ES01\Administrator has user sid S-1-5-21-1816646249-803782145-3669927669-500 but group sid S-1-5-21-3405883886-2425668597-4100599511-513.

• cPanel web server redundancy advice?

  - by crgnz

  At present I operate a (reasonably low volume) web-hosting service with a Centos 5.3 server running cPanel/WHM. I would like to implement a level of redundancy such that in the event of server failure, I can restore service with a minimum of effort in less than 60 minutes. I also want to setup a secondary DNS that cPanel will replicate with. My current idea is to kill two birds with one stone by: My current server is called "www1" Purchase an identical server (HP DL360 G4) with mirrored disks. Call this server "www2" Install Centos 5.4 (or perhaps I should install 5.3 to be identical with www1) Install cPanel/WHM on this server and fully license it Setup www1 and www2 cPanel to replicate DNS with each other Setup a nightly replication script that does the following: a) rsync's the /home directory from www1 to www2 b) dumps all MySQL databases on www1 and copies them to a temp folder (with root access only) on www2 c) triggers a script to run on www2 that restores the MySQL dumps Thus each night a fully working copy of all the websites and MySQL databases is copied to www2. I do not have enough knowledge of MySQL replication to understand if it works safely and transparently with cPanel. Thus I propose the mysql dump/copy/restore due to not knowing any better! In the event that www1 dies a horrible death, I envisage that I could login to www2, change the IP addresses to those that www1 had, and presto, the websites are available again. The advantage of this idea is that it is fairly simple and "low tech" and thus does not require an expert sysadmin to setup and monitor (I am NOT an expert sysadmin) The disadvantage of this idea is that up to a full days worth of data changes would be lost. I think this would be acceptable to the sorts of customers I host at the moment. The other disadvantage would be having to pay for a full cPanel license, but I am comfortable with that cost, so for now all I want to discuss are technical considerations. Is this a sound scheme?

• 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.

• Adding an user to samba

  - by JustMaximumPower

  I'm trying to setup some samba shares in my home network on an Ubuntu 12.04 machine. Everything works fine for my user account (max) but I can not add any new user. Every time I try to add new user they can not use the shares. It's likely that the error is very basic to the concept of samba but please don't just tell me to read the docs. I've been trying that for about 2 weeks now. I've set up the server with my user max who can mount transfer and the share max. Than I added the user simon with sudo adduser --no-create-home --disabled-login --shell /bin/false simon because the user should not be able to ssh into the machine. I did an sudo smbpasswd -a simon and set an (samba) password for simon and added an share for simon. I also added simon to transferusers to give him access to the share transfer. But simon can't connect to transfer or simons. ---- output of testparam: ------- Load smb config files from /etc/samba/smb.conf rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) Processing section "[printers]" Processing section "[print$]" Processing section "[max]" Processing section "[simons]" Processing section "[transfer]" Loaded services file OK.

• Prosody mod auth external not working

  I installed mod_auth_external for 0.8.2 on ubuntu 12.04 but it's not working. I have external_auth_command = "/home/yang/chat/testing" but it's not getting invoked.

• Can't connect to computer via SBS2011 RWA

  - by sbrattla

  I've got an SBS 2011 Essentials server. Users a able to log on to Remote Web Access using their username and password. However, the trouble starts when a users attempts to log on remotely to his/her computer from the Remote Web Access website. When the user clicks on his/her computer (in the RWA website), the user is first presented with a window listing Publisher, Type, Remote Computer name and Gateway Server. Everything seems fine here, and the user clicks Connect. The user credentials are provided, and a connection is attempted. However, the logon attempt always fails with the message "The logon attempt failed". The logon attempt always generates three log events in the server log: EventId: 4672 - Special Logon EventId: 4624 - Logon EventId: 4634 - Logoff All events happens have the same timestamp. No events are logged on the client machine which the user attempts to log on to. Others have solved this by going to their IIS server and enable "Windows Authentication" for Rpc and RpcWithCert (in Default Web Site). However, this is in place on the server. I've also got RD CAPs and RD RAPs in place. As a side note; if i try to connect to any of the machines using the Remote Desktop Connection using the "Connect from anywhere" functionality - then things work flawlessly! In other words, the error only occurs when attempting to login to a computer via the Remote Web Access website. I've run out of ideas for how I can solve this (too many hours spent). Any ideas highly appreciated!

• Postfix mail server: can't connect via POP/IMAP

  - by MelkerOVan

  I've followed this guide on setting up a mail server on my dedicated server. I've been able to send mails from the php application I'm using and the linux commandline (using telnet, php, etc). The problem is that I cannot connect to the server via IMAP/POP which I've setup using Courier. I've tried using thunderbird but it complains that the username or password is wrong. I doubt it is the username/password but I don't know how to trouble shoot this. Edit: Here's the messages in mail.log: Jan 9 22:43:38 mail authdaemond: received auth request, service=imap, authtype=login Jan 9 22:43:38 mail authdaemond: authmysql: trying this module Jan 9 22:43:38 mail authdaemond: SQL query: SELECT id, crypt, "", uid, gid, home, "", "", name, "" FROM users WHERE id = '[email protected]' AND (enabled=1) Jan 9 22:43:38 mail authdaemond: password matches successfully Jan 9 22:43:38 mail authdaemond: authmysql: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: authmysql: clearpasswd=<null>, passwd=6SrBcYq65l8QU Jan 9 22:43:38 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: Authenticated: clearpasswd=peter, passwd=6SrBcYq65l8QU Jan 9 22:43:38 mail imapd: chdir Maildir: No such file or directory

• How to use cURL to FTPS upload to SecureTransport (hint: SITE AUTH and client certificates)

• Apache Simple Configuration Issue: per-user directory is accessing /~user instead of ~user

  - by Huckphin

  Hello. I am just getting Apache 2.2 running on Fedora 13 Beta 64-bit. I am running into issues setting my per-user directory. The goal is to make localhost/~user map to /home/~user/public_html. I think that I have the permissions right because I have 755 to /home/~user, and I have 755 to /home/~user/public_html/ and I have 777 for all contents inside of /home/~user/public_html/ recursively set. My mod_userdir configuration looks like this: <IfModule mod_userdir.c> # # UserDir is disabled by default since it can confirm the presence # of a username on the system (depending on home directory # permissions). # UserDir disabled root UserDir enabled huckphin # # To enable requests to /~user/ to serve the user's public_html # directory, remove the "UserDir disabled" line above, and uncomment # the following line instead: # UserDir public_html The error that I am seeing in the error log is this: [Sat May 15 09:54:29 2010] [error] [client 127.0.0.1] (13)Permission denied: access to /~huckphin/index.html denied When I login as the apache user, I know that /~huckphin does not exist, and this is not what I want. I want it to be accessing ~huckphin, not /~huckphin. What do I need to change on my configuration for this to work?

• Per client DNS server assignment using Pfsense

  - by Trix

  I have a network where pfsense is the gateway. There are two sets of clients that I want. One where there will be some restrictions to the network (example, IM being blocked) and one network where there are no restrictions. One easy way I thought about doing this was assigning the different domains different DNS servers. One set could use OpenDNS, the other could use Google's Public DNS. The set with OpenDNS would have the filter options on (using OpenDNS' dashboard, I can check block IM .... so I do not manually need to block login.oscar.aol.com, meebo.com, gmail chat ....etc). So the problem is the DHCP server looks like it will only assign a single set of DNS servers to clients. Is there a way to set a per client assignment? Is there a better way to obtain what I want to obtain. This is just a small home network. I do not need anything fancy, but I do need this functionality in one way or another.

• Office Communicator and cannot sync Address book error

  - by Noah

  We are trying to get OCS 2007 R2 up and running. The clients login fine, but when I let it sit for a while, we still get the address book sync error message of: "Cannot synchronize with the corporate address book. This may be because the proxy server setting in your web browser does not allow access to the address book. If the problem persists, contact your system administrator". When I try and download the file locally, this error comes up: Could not load file or assembly 'ABServerHttpHandler, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. Failed to grant minimum permission requests. (Exception from HRESULT: 0x80131417) I googled and came across this post (http://social.technet.microsoft.com/Forums/en/ocsaddressbook/thread/c28ff2d8-66a4-456c-a5ad-e445a667e8ed) which suggests removing and reinstalling .NET 2.0 but that didn't seem to resolve the issue either. When we run abserver.exe -validateDB it works properly. We even tried the suggestion from Greg's Blog (http://blogs.technet.com/greganth/archive/2009/03/11/office-communicator-notifications-cannot-synchronize-address-book.aspx) about restarting the web component services but that didn't work either. Still seeing the same issue. So does anyone have an idea of where we go from here?
