• Firefox not using Kerberos despite being configured to

  - by Nicolas Raoul

  I am deploying Linux/Firefox on a corporate Kerberos network. I followed this Kerberos-on-Firefox procedure but still Firefox does not connect via the company's Kerberos. I am using Firefox 3.0.18 on RedHat EL Server 5.5 Here is what I did: Run kinit on the command line to create a Kerberos ticket Check with klist: the ticket is valid until tomorrow, service principal is krbtgt/[email protected]. In Firefox, set network.negotiate-auth.trusted-uris and network.negotiate-auth.delegation-uris to .dc.thecompany.com. Load the company's portal page via its full hostname: http://server37.thecompany.com/alfresco. (note: server37 is actually the machine I am running Firefox on, but that should not be a problem I guess) PROBLEM: the company's intranet portal still serves me the login/password page. The same portal correctly uses Kerberos on Internet Explorer/Windows 7 machines, same settings, and shows the user's personal page. The server does not see any Kerberos request coming. Did I do something wrong? I enabled NSPR_LOG_MODULES=negotiateauth:5 as explained here, but the log file stays empty.

• SFTP, Chroot problems on Redhat

  - by Curtis_w

  I'm having problems setting up sftp with a ChrootDirectory. I've done an equivalent setup on other distros, but for some reason I cannot get it to work on a Redhat AMI. The changes to my sshd_config file are: Subsystem sftp internal-sftp Match Group ftponly PasswordAuthentication yes X11Forwarding no ChrootDirectory %h ForceCommand internal-sftp AllowTcpForwarding no I have the concerned usere's homes at /home/user, owned by root. After connecting with a user in the ftponly group, I'm dropped into / without permissions for anything, and am unable to do anything. sftp bob@localhost Connecting to localhost... bob@localhost's password: sftp> pwd Remote working directory: / I can connect normally with users not in the ftponly group. openssh version 5.3 I've experimented with different permissions, as well as having users own their own home directory (gives a Write failed: Broken pipe error), and so far, nothing has seemed to work. I'm sure it's a permissions error, or something equally as trivial, but at this point my eyes are beginning to glaze over, and any help would be greatly appreciated. EDIT: James and Madhatter, thanks for clarifying. I was confused by chroot dropping me in /... just didn't think through it properly. I've added the appropriate directories and permissions to get read access. One other key part was enabling write access to chrooted homes: setsebool -P ssh_chroot_rw_homedirs on in order to get write access. I think I'm all set now. Thanks for the help.

• 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.

• Getting SMB file shares working over a PPTP VPN

  - by Ben Scott

  I'm having issues getting SMB file shares working over a PPTP VPN. The server setup consists of a security device (DrayTek V3300) which passes the PPTP authentication to a SBS2003 server running RRAS. The server is the DC and provides DNS and WINS, the single NIC's name server is set to 127.0.0.1, and DHCP on the DrayTek sets the server IP as the DNS. If I create a new VPN connection in Win7, leaving everything as default apart from the server, username, password and domain, I can: ping everything by IP address resolve IPs with nslookup using their fully-qualified name, as in nslookup fileserver.mydomain.local ping machines by fully-qualified name, as in ping fileserver.mydomain.local However if I try to access a file share: within Explorer, I get "Windows cannot access ..." with "Error code: 0x80004005 Unspecified Error", using net use z: \\fileserver.mydomain.local\share, I get "System error 53 has occurred. The network path was not found." If I add the machine name to my HOSTS file I can use the file share, which is my last-ditch workaround, but I have a number of VPN users and would rather a solution that doesn't involve me trying to hand-edit system files on computers half a country away. If I set the WINS server explicitly in the connection's IPv4 settings I don't have to use the FQN to ping the machine, but that doesn't change anything else.

• What ways are there to set permissions on an Exchange 2003 mailbox?

  - by HopelessN00b

  I'm having a difficult/impossible time tracing down a permissions issue on an Exchange 2003 mailbox, and I was wondering if I'm missing any technical possibilities here. The basic question is what ways are there to set a user's permissions to access a mailbox in Exchange 2003? I know of two. Permissions on the mailbox itself (Mailbox Rights) and having delegated rights. And then, if it's possible, how would one view all the permissions (including delegated permissions) on the mailbox? The situation is that a new user who's been set up "exactly like all the others" in his department (pretty sure he was copied via the right click option in ADUC, in fact) can't access a specific shared mailbox, which I've been assured about a dozen other people do have access to and access on a regular basis. As to how they got permissions to the mailbox, no one knows, so it must have been granted by a white wizard whose spell has since worn off, so now IT has to handle it instead. Anyway... This mailbox is a normal AD user, created as a service account, for which no one knows the password (of course), so it's probably not the case that this service account was being used to delegate permissions. Upon taking examining the Mailbox Rights directly... Here are the permissions I see: This leads me to believe that one of two things are happening - the managers have been delegating full mailbox permissions to the rest of the department, or everyone's logging in using... not their own account. But, before I get too excited about the prospect of busting out the LART and strolling over to that department, I want to make sure I'm not missing another possible explanation. Like most of the rest of the world, I ditched Exchange 2003 at the earliest possible opportunity, and had been looking forward to never seeing it again, so I'm a bit rusty on the intricacies of how it [mostly, sort of] works. Anyone see any or possibilities, or things I may have missed, or does the LART get to come out and play?

• 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 )

• 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.

• 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).

• Setup 2003 R2 Radius server to work on vista/seven

  - by Fox

  Hi All, I'm currently trying to configure my 2003 R2 server RADIUS module to enable WIFI client to authenticate throught my Active Directory. The RADIUS server use MS-CHAP V2 as encryption method. I got several Access Point running DD-WRT, configured to use WPA2-Enterprise security that use Radius Server. Everything is setup, and almost working. When I say almost working, I mean, I can login using my AD Credential on my IPod or even on a MacBook running OS X, Windows XP also work with some little tweak in connection properties. The problem is Windows Vista or Windows Seven clients computers that are not inside domain. It doesn't work at all, it doesn't even prompt for user/password/domain. I already install the patch for IAS to make the certsrv compatible with Vista and Seven, but still doesn't work. Anyone ever encounter the same issue I have right now? I'm searching for a solution to this for several already and still not find anything. Looks like many people have the same issue too. Thanks all for you eventual answers.

• Unattended Kickstart Install

  - by Eric

  I've looked around quite a bit and have seen similar setup and questions, but none seem to work for me. I'm using the following command to create a custom ISO: /usr/bin/livecd-creator --config=/usr/share/livecd-tools/test.ks --fslabel=TestAppliance --cache=/var/cache/live This works great and it creates the ISO with all of the packages and configs I want on it. My issue is that I want the install to be unattended. However, every time I start the CD, it asks for all of the info such as keyboard, time zone, root password, etc. These are my basic settings I have in my kickstart script prior to the packages section. cdrom install autopart autostep xconfig --startxonboot rootpw testpassword lang en_US.UTF-8 keyboard us timezone --utc America/New_York auth --useshadow --enablemd5 selinux --disabled services --enabled=iptables,rsyslog,sshd,ntpd,NetworkManager,network --disabled=sendmail,cups,firstboot,ip6tables clearpart --all So after looking around, I was told that I need to modify my isolinux.cfg file to either do "ks=http://X.X.X.X/location/to/test.ks" or "ks=cdrom:/test.ks". I've tried both methods and it still forces me to go through the install process. When I tail the apache logs on the server, I see that the ISO never even tries to get the file. Below are the exact syntax I'm trying on my isolinux.cfg file. label http menu label HTTP kernel vmlinuz0 append initrd=initrd0.img ks=http://192.168.56.101/files/test.ks ksdevice=eth0 label localks menu label LocalKS kernel vmlinuz0 append initrd=initrd0.img ks=cdrom:/test.ks label install0 menu label Install kernel vmlinuz0 append initrd=initrd0.img root=live:CDLABEL=PerimeterAppliance rootfstype=auto ro liveimg liveinst noswap rd_NO_LUKS rd_NO_MD rd_NO_DM menu default EOF_boot_menu The first 2 give me a "dracut: fatal: no or empty root=" error until I give it a root= option and then it just skips the kickstart completely. The last one is my default option that works fine, but just requires a lot of user input. Any help would be greatly appreciated.

• 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.

• 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.

• pppd disconnects from 3G, doesn't reconnect, w/ persist set

  - by bytenik

  I am trying to configure pppd to connect to a 3G network (Sprint, in this case) and then stay connected, reconnecting automatically if the remote connection is terminated. I have enabled the persist option. My configuration file is as follows: hide-password noauth connect "/usr/sbin/chat -v -f /etc/chatscripts/cellular" debug /dev/cell 921600 defaultroute noipdefault user " " persist maxfail 0 lcp-echo-failure 10 lcp-echo-interval 60 holdoff 5 However, when the peer disconnects the connection, pppd often waits a long time (substantially more than my holdoff) to reconnect the modem -- if it ever reconnects at all! An example log showing this: May 23 05:17:24 00270e0a8888 pppd[2408]: rcvd [LCP TermReq id=0x26] May 23 05:17:24 00270e0a8888 pppd[2408]: LCP terminated by peer May 23 05:17:24 00270e0a8888 pppd[2408]: Connect time 60.1 minutes.

I had a friend monitoring the server so I'm not certain that this wasn't a manual reconnection. Either way, it either took almost an hour to reconnect or never reconnected. Shouldn't persist + holdoff 5 cause this to automatically reconnect after 5 seconds of the link terminating?

• 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!

• 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

• 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?

• 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?

• 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?

• 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. [301, #0] [Mon May 03 16:40:00 2010] [error] [client 192.168.19.13] Requests for a collection must have a trailing slash on the URI. [301, #0] My question: Can I restrict access to Subversion subdirectories using Apache access controls? DocumentRoot is commented out, so it's not clear that the FAQ at http://subversion.apache.org/faq.html#http-301-error applies.

• 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

• 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

• Postfix misconfigured? 550 Sender rejected from recieving server

  We use Postfix on our CentOS 6 machine, having the following configuration. We use PHP's mail() function to send rudimentary password reset emails, but there is a problem. As you will see, mydomain and myhostname is correctly set, afaik. alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 html_directory = no inet_interfaces = localhost inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost mydomain = ***.ch myhostname = test.***.ch newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop unknown_local_recipient_reject_code = 550 Now this is the stuff that is in the /var/log/maillog of Postfix upon sending an email to ***.***@***.ch, with ***.ch being the same domain our sending server test.***.ch is on: Dec 13 16:55:06 R12X0210 postfix/pickup[6831]: E6D6311406AB: uid=48 from=<apache> Dec 13 16:55:06 R12X0210 postfix/cleanup[6839]: E6D6311406AB: message-id=<20121213155506.E6D6311406AB@test.***.ch> Dec 13 16:55:07 R12X0210 postfix/qmgr[6832]: E6D6311406AB: from=<apache@test.***.ch>, size=1276, nrcpt=1 (queue active) Dec 13 16:55:52 R12X0210 postfix/smtp[6841]: E6D6311406AB: to=<***.***@***.ch>, relay=mail.***.ch[**.**.249.3]:25, delay=46, delays=0.18/0/21/24, dsn=5.0.0, status=bounced (host mail.***.ch[**.**.249.3] said: 550 Sender Rejected (in reply to RCPT TO command)) Dec 13 16:55:52 R12X0210 postfix/cleanup[6839]: 8562C11406AC: message-id=<20121213155552.8562C11406AC@test.***.ch> Dec 13 16:55:52 R12X0210 postfix/bounce[6848]: E6D6311406AB: sender non-delivery notification: 8562C11406AC Dec 13 16:55:52 R12X0210 postfix/qmgr[6832]: 8562C11406AC: from=<>, size=3065, nrcpt=1 (queue active) Dec 13 16:55:52 R12X0210 postfix/qmgr[6832]: E6D6311406AB: removed Dec 13 16:55:52 R12X0210 postfix/local[6850]: 8562C11406AC: to=<root@test.***.ch>, orig_to=<apache@test.***.ch>, relay=local, delay=0.13, delays=0.07/0/0/0.05, dsn=2.0.0, status=sent (delivered to mailbox) Dec 13 16:55:52 R12X0210 postfix/qmgr[6832]: 8562C11406AC: removed So the receiving server rejects the sender (line 4 of log output). 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.

• 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)? Otherwise, how can I solve this? It's my first time configuring this feature, but I definitely believe it's part of my IOS. Speaking of my IOS, I'm running the image c2800nm-advsecurityk9-mz.124-24.T6.bin I'll also note that I have my hostname and ip domain-name configured. I'll also give you a dir flash: below if it's at all of use: better#dir flash: Directory of flash:/ 2 -rw- 2748 Jul 27 2009 14:03:52 +00:00 sdmconfig-2811.cfg 3 -rw- 931840 Jul 27 2009 14:04:10 +00:00 es.tar 4 -rw- 1505280 Jul 27 2009 14:04:32 +00:00 common.tar 5 -rw- 1038 Jul 27 2009 14:04:46 +00:00 home.shtml 6 -rw- 112640 Jul 27 2009 14:05:00 +00:00 home.tar 7 -rw- 1697952 Jul 27 2009 14:05:26 +00:00 securedesktop-ios-3.1.1.45-k9.pkg 8 -rw- 415956 Jul 27 2009 14:05:46 +00:00 sslclient-win-1.1.4.176.pkg 9 -rw- 38732900 Dec 8 2011 06:28:56 +00:00 c2800nm-advsecurityk9-mz.124-24.T6.bin 64016384 bytes total (20598784 bytes free) better#

• 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!

• 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".
