  • How to give a user NTFS rights to a folder, via Powershell

    - by Don
    I'm trying to build a script that will create a folder for a new user on our file server. Then take the inherited rights away from that folder and add specific rights back in. I have it successfully adding the folder (if i give it a static entry in the script), giving domain admin rights, removing inheritance, etc...but i'm having trouble getting it to use a variable I set as the user. I don't want there to be a static user each time, I want to be able to run this script, have it ask me for a username, it then goes out and creates the folder, then gives that same user full rights to that folder based on the username i've supplied it. I can use Smithd as a user, like this: New-Item \\fileserver\home$\Smithd –Type Directory But can't get it to reference the user like this: New-Item \\fileserver\home$\$username –Type Directory Here's what i have: Creating a new folder and setting NTFS permissions. $username = read-host -prompt "Enter User Name" New-Item \\\fileserver\home$\$username –Type Directory Get-Acl \\\fileserver\home$\$username $acl = Get-Acl \\\fileserver\home$\$username $acl.SetAccessRuleProtection($True, $False) $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Administrators","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow") $acl.AddAccessRule($rule) $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Domain\Domain Admins","FullControl", "ContainerInherit, ObjectInherit", "None", "Allow") $acl.AddAccessRule($rule) $rule = New-Object System.Security.AccessControl.FileSystemAccessRule("Domain\"+$username,"FullControl", "ContainerInherit, ObjectInherit", "None", "Allow") $acl.AddAccessRule($rule) Set-Acl \\\fileserver\home$\$username $acl I've tried several ways to get it to work, but no luck. Any ideas or suggestions would be welcome, thanks.

  • Whitelist IP from google-authenticator in sshd pam

    - by spudwaffle
    My Ubuntu 12.04 server uses the google-authenticator pam module to provide two step authentication for ssh. I need to make it so that a certain IP does not need to type the verification code. The /etc/pam.d/sshd file is below: # PAM configuration for the Secure Shell service # Read environment variables from /etc/environment and # /etc/security/pam_env.conf. auth required pam_env.so # [1] # In Debian 4.0 (etch), locale-related environment variables were moved to # /etc/default/locale, so read that as well. auth required pam_env.so envfile=/etc/default/locale # Standard Un*x authentication. @include common-auth # Disallow non-root logins when /etc/nologin exists. account required pam_nologin.so # Uncomment and edit /etc/security/access.conf if you need to set complex # access limits that are hard to express in sshd_config. # account required pam_access.so # Standard Un*x authorization. @include common-account # Standard Un*x session setup and teardown. @include common-session # Print the message of the day upon successful login. session optional pam_motd.so # [1] # Print the status of the user's mailbox upon successful login. session optional pam_mail.so standard noenv # [1] # Set up user limits from /etc/security/limits.conf. session required pam_limits.so # Set up SELinux capabilities (need modified pam) # session required pam_selinux.so multiple # Standard Un*x password updating. @include common-password auth required pam_google_authenticator.so I've already tried adding a auth sufficient pam_exec.so /etc/pam.d/ip.sh line above the google-authenticator line, but I can't understand how to check an IP adress in the bash script.

  • OpenLDAP, howto allow both secure (TLS) and unsecure (normal) connections?

    - by Mikael Roos
    Installed OpenLDAP 2.4 on FreeBSD 8.1. It works for ordinary connections OR for TLS connections. I can change it by (un)commenting the following lines in slapd.conf. # Enable TLS #security ssf=128 # Disable TLS security ssf=0 Is there a way to allow the clients to connect using TLS OR no-TLS? Can the ldap-server be configured to support both TLS connections and no-TLS connections? Tried to find the information in the manual, but failed: http://www.openldap.org/doc/admin24/access-control.html#Granting%20and%20Denying%20access%20based%20on%20security%20strength%20factors%20(ssf) http://www.openldap.org/doc/admin24/tls.html#Server%20Configuration Tried to read up on 'security' in manualpage for ldap.conf, didn't find the info there either. I guess I need to configure the 'secure' with some negotiation mechanism, "try to use TLS if client has it, otherwise continue using no-TLS". Connecting with a client (when slapd.conf is configure to use TLS): gm# ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts ldap_bind: Confidentiality required (13) additional info: TLS confidentiality required gm# ldapsearch -Z -x -b '' -s base '(objectclass=*)' namingContexts (this works, -Z makes a TLS connection) So, can I have my ldap-server supporting client connections using TLS and ordinary (no-TLS) connections? Thanx in advance.

  • After update, suddenly lost ability to access Windows Server 2008 R2 shares from Windows XP clients

    - by Knute Knudsen
    Today I lost the ability to see my Windows Server 2008 R2 shares from any of my 3 Windows XP machines in my small office. The 5 Win7 machines haven't been affected (they are still able to browse/access the 2008 server), but none of my WinXP machines can access the 2008R2 server anymore. Yesterday (and for the previous year) everything was working fine. I do not have a domain setup. I can still access Win7 shares from WinXP clients. Browsing the server logs, I see that the following update was installed last night: > Installation Ready: The following updates are downloaded and ready for > installation. This computer is currently scheduled to install these > updates on ?Thursday, ?November ?15, ?2012 at 3:00 AM: > - Security Update for Windows Server 2008 R2 x64 Edition (KB2761226) > - Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2729452) > - Windows Malicious Software Removal Tool x64 - November 2012 (KB890830) > - Cumulative Security Update for Internet Explorer 9 for Windows Server 2008 R2 x64 Edition (KB2761451) It seems likely that something was changed in last night's update, but so far I haven't seen anything on microsoft.com to prove it. I did hear that XP is reaching the end of the road soon. Any ideas?

  • Group Policy GPO not 'seen' at client

    - by fukawi2
    I have a new OU (natorg.local\NATO\Users) that I am trying to apply GP to. I have created a new user in this OU, and linked the 3 GPO's to this OU: DESKTOP - Folder Redirection (AppData) DESKTOP - Folder Redirection (Desktop) DESKTOP - Folder Redirection (Documents) Hopefully the names are sufficient to suggest what they do exactly. The settings are under User Settings so there is no Loopback processing required (if my understanding is correct). GP Modelling for the user and specific computer says that the GPOs will/should be applied, however on the client, gpresult doesn't even appear to see the GPOs under either "Applied" or "Not Applied": USER SETTINGS -------------- CN=Amir,OU=Users,OU=NATO,DC=natorg,DC=local Last time Group Policy was applied: 25/06/2012 at 11:07:13 AM Group Policy was applied from: svr-addc-01.natorg.local Group Policy slow link threshold: 500 kbps Applied Group Policy Objects ----------------------------- LAPTOPS - Power Settings WSUS - Set Server Address OUTLOOK - Auto Archive SECURITY - Lock Screen After Idle Default Domain Policy DESKTOP - Regional Settings NETWORK - Proxy Configuration NETWORK - IE General Config OFFICE - Trusted Locations OFFICE - Increase Privacy OUTLOOK - Disable Junk Filter DESKTOP - Disable Windows Error Reporting DESKTOP - Hide Language Bar NETWORK - Disable Skype DESKTOP - Disable Thumbs.db Creation WSUS - Set Server Address The following GPOs were not applied because they were filtered out ------------------------------------------------------------------- Local Group Policy Filtering: Not Applied (Empty) NETWORK - Google Chrome Configuration Filtering: Not Applied (Empty) SYSTEM - Event Log Configuration Filtering: Not Applied (Empty) SECURITY - Local Administrator Password Filtering: Not Applied (Empty) NETWORK - Disable Windows Messenger Filtering: Not Applied (Empty) SECURITY - Audit Policy Filtering: Not Applied (Empty) WSUS - Automatic Install Filtering: Not Applied (Empty) NETWORK - Firewall Configuration Filtering: Not Applied (Empty) DESKTOP - Enable Offline Files Filtering: Not Applied (Empty) I haven't altered permissions on the GPO's at all, no WMI filtering... As I said, GP Modelling says that they should be applied. GPResult on the client correctly identifies itself as being the correct OU (CN=Amir,OU=Users,OU=NATO,DC=natorg,DC=local) There are 2 x 2008R2 and a 2003 DC, domain is 2003 level, client is Windows XP SP3. Can anyone suggest why these GP Objects would be "invisible" to the client?

  • EC2 Configuration

    - by user123683
    I am trying to create a server structure for my EC2 account. The design I have chosen consists of 2 instances running in different availability zones, elastic load balancer, an auto-scaling group with cloudwatch monitoring configured and a security group defining rules for access to the instances. This setup is to support an online web application written in PHP. I am trying to decide what is a better policy: Store MySQL DB on a separate Instance Store MySQL DB on an attached EBS volume (from what i know auto-scaling will not replicate the attached EBS volume but will generate new instances from a chosen AMI - is this view correct?) Regards the AMI I plan to use a basic Amazon linux 64 bit AMI, and install bastille (maybe OSSEC) but I am looking to also use an encrypted file system. Are there any issues using an encrypted file system and communication between the DB and webapp i neeed to be aware of? Are there any comms issues using the encrypted filesystem on the instance housing the webapp I was going to launch a second instance or attach a second volume in the second availability zone to act as a standby for the database - I'm just looking for some suggestions about how to get the two DB's to talk - will this be a big task Regards updates for security is it best to create a recent snapshot and just relaunch and allow Amazon to install updates on launch or is the yum update mechanism a suitable alternative - is it better practice to relaunch instead of updates being installed which force a restart. I plan to create two AMI snapshots one for the app server and one for the DB each with the same security measures in place - is this a reasonable - I just figure it is a better policy than having additional applications that are unnecessary included in a AMI that I intend on using. My plan for backup is to create periodic snapshots of the webapp and DB instances (if I use an additional EBS volume instead of separate instances my understanding is that the EBS volume will persist in S3 storage in the event of an unexpected termination and I can create snapshots of the volume backup purposes). Thanks in advance for suggestions and advice. I am new to EC2 and I may have described unnecessary overkill but I want to try implement what can be considered a best practice solution so all advice is appreciated.

  • Read access to Active Directory property (uSNCreated)

    - by Tom Ligda
    I have an issue with read access to the uSNCreated property when doing LDAP searches. If I do an LDAP search with a user that is a member of the Domain Admins group (UserA), I can see the uSNCreated property for every user. The problem is that if I do an LDAP search with a user (UserB) that is not a member of the Domain Admins group, I can see the uSNCreated property for some users (UserGroupA) and not for some users (UserGroupB). When I look at the users in UserGroupA and compare them to the users in UserGroupB, I see a crucial difference in the "Security" tab. The users in UserGroupA have the "Include inheritable permissions from this object's parent" unchecked. The users in UserGroupB have that option checked. I also noticed that the users in UserGroupA are users that were created earlier. The users in UserGroupB are users created recently. It's difficult to quantify, but I estimate the border between creation time between the users in UserGroupA and UserGroupB is about 6 months ago. What can cause the user creation to default to having that security property checked as opposed to unchecked? A while back (maybe around 6 months ago?) I changed the domain functional level from Windows Server 2003 to Windows Server 2008 R2. Would that have had this effect? (I can't exactly downgrade the domain functional level to test it out.) Is this security property actually the cause of the issue with read access to the uSNChanged property on LDAP searches? It seems correlated, but I'm not sure about causation. What I want in the end is for all authenticated users to have read access to the uSNCreated property for all users when doing an LDAP search. I would also be OK if I could grant read access for that property to an AD group. Then I can control access by adding members to the group.

  • Is it possible to repair a Cisco 3500 XL (3548) switch with POST Error messages?

    - by Alex
    I've got an old Cisco 3500 XL, and it seems to have hardware issues. I've loaded the latest IOS and cleared all config. Does anyone have any experience fixing the switch core? I'm a reasonably competent SMD solderer, can I replace/reflow some chips? I've checked the power supply voltages and it's all within tolerance, and no visible signs of any component damage. Some chips are hot to the touch. I understand that these were EOL as of 2007, but should have a lifetime warranty for the electronics. I don't have a Cisco support contract, so I can't file a ticket. What should I do?

  • Dell fumbles OpenManage installation process, forgets to write documentation?

    - by bwerks
    Hi all, I'm setting up a Dell PowerEdge 2950 for a small business, and I've just spent a while with Dell OpenManage Server Administrator 6.2, trying to clear the installation process of errors before I execute it. Right now I'm getting the following warning from the installer. The installer has detected that the HTTPS listener is not configured for Windows Remote Management. You can either configure the HTTPS listener before installing Remote Enablement, or install Remote Enablement now by selecting the "Custom" installation screen and configure the HTTPS listener later. See the "Remote Enablement Requirements" section in the "Dell OpenManage Installation and Security User's Guide" for information on configuring the HTTPS listener. Note: Remote Enablement is required to manage this system from a remote Server Administrator Web Server and is applicable only for those systems that support Server Instrumentation. Click here to configure HTTPs Listener for Windows Remote Management. The italicized line is a link, which executes...something...via cmd, and doesn't seem to help the problem. Not knowing exactly what to do here, I consulted the documentation. I read through the Setup and Administration section of the User's Guide, but all that it contained was a weird primer on role-based security and some SNMP stuff. The next section skips installation entirely and moved on to features of the suite. Thinking myself crazy, I consulted the readme, which told me that for installation I should consult the "Dell OpenManage Installation and Security Version 6.2 User's Guide" which not only doesn't exist in the documentation, but also not in all of google? Soo yeah, if anyone is familiar with this problem, drop me some knowledge!

  • Terminal Server 2008: Remote App Issue

    - by JohnyD
    I have a FoxPro 2.6 (16-bit) application that I've installed on a Win2008 (32-bit) Terminal Server. I then created a Remote App from it. It works fine. The problem is that within this FoxPro application it calls out to a .Net application. I have the proper .Net Framework installed on the server (2.0) and I have run the code access security policy tool (caspol.exe). However, when I launch the .Net app from within the FoxPro application I get the following error: Description: Stopped working Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: vector.exe Problem Signature 02: 1.0.0.3 Problem Signature 03: 48b579f2 Problem Signature 04: vector Problem Signature 05: 1.0.0.3 Problem Signature 06: 48b579f2 Problem Signature 07: f Problem Signature 08: 57 Problem Signature 09: System.Security.Security OS Version: 6.0.6001.2.1.0.18.10 Locale ID: 1033 Vector.exe is our .Net application. In fact, it's an in-between application that checks to ensure you have the latest version. When it's done it calls out to another .Net executable. Does anyone believe this should be a problem? Thanks in advance.

  • CryptSvc not matched by Windows 7 Firewall rule

    - by theultramage
    I am using Windows Firewall in conjunction with a third-party tool to get notified about new outbound connection attempts (Windows Firewall Notifier or Windows Firewall Control). The way these tools do it is by setting the firewall to deny by default, and to add an auditing policy to log blocked connections into the Security event log. Then they watch the log, and display notification about newly added entries. netsh advfirewall set allprofiles firewallpolicy blockinbound,blockoutbound auditpol /set /subcategory:{0CCE9226-69AE-11D9-BED3-505054503030} /failure:enable With this configuration in place, I now need to craft outbound allow rules for applications and system services. Here is the rule for CryptSvc, the service frequently used for certificate validation and revocation checking: netsh advfirewall firewall add rule name="Windows Cryptographic Services" action=allow enable=yes profile=any program="%SystemRoot%\system32\svchost.exe" service="CryptSvc" dir=out protocol=tcp remoteport=80,443 The problem is, this rule does not work. Unless I change the scope to "all programs and services" (which is really unhealthy), connection denied events like the following will keep appearing in the security log: Event 5157, Microsoft Windows security auditing. The Windows Filtering Platform has blocked a connection. Application Information: Process ID: 1476 (<- svchost.exe with CryptSvc and nothing else) Application Name: \device\harddiskvolume1\windows\system32\svchost.exe Network Information: Direction: Outbound Source Address: 192.168.0.1 Source Port: 49616 Destination Address: 2.16.52.16 Destination Port: 80 Protocol: 6 (<- TCP) To make sure it's CryptSvc, I have let the connection through and reviewed its traffic; I also configured CryptSvc to run in its own svchost instance to make it more obvious: ;sc config CryptSvc type= share sc config CryptSvc type= own So... why is it not matching the firewall rule, and how to fix that?

  • Using our own certificate authority for business email encryption

    - by LumenAlbum
    I've read the available similar questions on serverfault but I haven't quite found a definite answer to the security aspect of it - hence here's my question: I'm administrator of an office working with tax data and we want to start using certificate-based eMail encryption with our clients. Considering the prices for issued certificates by VeriSign & Co I was wondering if we couldn't issue the necessary certificates with a certificate authority of our own. I realize that they do not offer the trust hierarchy that commercial certificates do but I don't see why we would need that. Most of our clients have small businesses and only 20% of them even exchange data with us via email. So if we were to issue certificates for those 20% and our employees, that would enable us to use encrypted emails. Of course they would have to trust our certificate authority and thus once receive our public root certificate. But if we would hand them out to them (or install it) personally, they'd know that it really is our certificate. Is thery a huge security risk that I am missing here? As long as nobody has access to our certificate authority server nobody should be able to interfere with security, right? And the client certificates would be generated and handed out by us, as well... Please advise me if I am making an error in judgement here and thank you in advance.

  • Reverse and Forward DNS set up correctly but sometimes MapReduce job fails

    Ever since we switched over our cluster to communicate via private interfaces and created a DNS server with correct forward and reverse lookup zones, we get this message before the M/R job runs: ERROR org.apache.hadoop.hbase.mapreduce.TableInputFormatBase - Cannot resolve the host name for /192.168.3.9 because of javax.naming.NameNotFoundException: DNS name not found [response code 3]; remaining name '9.3.168.192.in-addr.arpa' A dig and nslookup both show that the reverse and forward look-ups both get good responses with no errors from within the cluster.

  • Which is more secure: Tomcat standalone or Tomcat behind Apache?

    - by NoozNooz42
    This question is not about performance, nor about load-balancing, etc. Which would be more secure: running Tomcat in standalone mode or running Tomcat behind apache? The thing is, Tomcat is written in Java and hence it is pretty much immune to buffer overrun/overflow (unless a buffer overrun in a C-written lib used by Tomcat can be triggered, but they're rare [the last I remember was in zlib, many many moons ago] and one heck of a hack to actually exploit), which gets rid of a lot of potential exploits. This page: http://wiki.apache.org/tomcat/FAQ/Security has this to say: There have been no public cases of damage done to a company, organization, or individual due to a Tomcat security issue... there have been only theoretical vulnerabilities found. All of those were addressed even though there were no documented cases of actual exploitation of these vulnerabilities. This, combined with the fact that buffer overrun/overflow are pretty much non-existent in Java, makes me believe that Tomcat in standalone mode is pretty secure. In addition to that, I can install both Java and Tomcat on Linux without needing to be root. The only moment I need to be root is to set up a transparent port 8080 to port 80 forwarding (and 8443 to 443). Two iptables line as root, that's all root is needed for. (I don't know for Apache). Apache is much more used than Tomcat and definitely does not have a security track record as good as Tomcat. What would make Tomcat + Apache more secure? What would make Tomcat + Apache less secure? In short: which is more secure, Tomcat standalone or Tomcat with Apache? (remembering that performance aren't an issue here)

  • How to Eliminate Tape Backup and Off-site Storage Service?

    - by Daniel Lucas
    PLEASE READ UPDATE AT THE BOTTOM. THANKS! ;) Environment Info (all Windows): 2 sites 30 servers site #1 (3TB of backup data) 5 servers site #2 (1TB of backup data) MPLS backbone tunnel connecting site #1 and site #2 Current Backup Process: Online Backup (disk-to-disk) Site #1 has a server running Symantec Backup Exec 12.5 with four 1TB USB 2.0 disks. BE jobs for full backups run nightly on all servers in site #1 to these disks. Site #2 backs up to a central file server there using software they already had when we purchased them. A BE job pulls that data nightly to site #1 and stores them on said disks. Off-site Backup (tape) Connected to our backup server is a tape drive. BE backs up the external disks to tape once a week which gets picked up by our off-site storage company. Obviously we rotate two tape libraries, one is always here and one is always there. Requirements: Eliminate the need for tape and off-site storage service by doing disk-to-disk at each site and replicating site #1 to site #2 and vice versa. Software based solution as hardware options have been too pricey (ie, SonicWall, Arkeia). Agents for Exchange, SharePoint, and SQL. Some Ideas So Far: Storage DroboPro at each site with an initial 8TB of storage (these are expandable up to 16TB at present). I like these because they are rackmountable, allow disparate drives, and have iSCSI interfaces. They are relatively cheap too. Software Symantec Backup Exec 12.5 already has all the agents and licenses we need. I'd like to keep using it unless there is a better solution, similarly priced, that does everything BE does plus deduplication and replication. Server Because there is no more need for a SCSI adapter (for tape drive) we are going to virtualize our backup server as it is currently the only physical machine save for SQL boxes. Problems: When replicating between sites we want as little data as possible to go across the pipe. There is no deduplication or compression in what I have laid out here so far. The files being replicated are BE's virtual tape libraries from our disk-to-disk backup. Because of this each of those huge files will go across the wire every week because they change every day. And Finally, the Question: Is there any software out there that does deduplication, or at least compression, to handle just our site-to-site replication? Or, looking at our setup, is there any other solution that I am missing that might be cheaper, faster, better? Thanks. Sorry so long. UPDATE 2: I've set a bounty on this question to get it more attention. I'm looking for software that will handle replication of data between two sites using the least amount of data possible (either compression, deduplication, or some other method). Something similar to rsync would work but it needs to be native to Windows and not a port involving shenanigans to get up and running. Prefer a GUI based product and I don't mind shelling out a few bones if it works. Please, answers that meet the above criteria only. If you don't think one exists or if you think I'm being to restrictive keep it to yourself. If after seven days there is no answer at all, so be it. Thanks again everyone. UPDATE 2: I really appreciate everyone coming forward with suggestions. There is no way for me to try all of these before the bounty expires. For now I'm going to let this bounty run out and whoever has the most votes will get the 100 rep points. Thanks again!

  • Nginx and automatic updates

    - by Desmond Hume
    I'm on Ubuntu 12.04.1 with unattended-upgrades configured for automatic security updates, and I installed Nginx by first adding deb http://nginx.org/packages/ubuntu/ lucid nginx deb-src http://nginx.org/packages/ubuntu/ lucid nginx to /etc/apt/sources.list file, just as was suggested by the official wiki, and then by sudo apt-get update sudo apt-get install nginx which installed Nginx with all the standard modules. But now I think I could make good use of one or two of the Nginx optional modules, like the gzip precompression module or some security-related one. So far, I see two ways of adding an optional module to Nginx, one is compiling and installing from the source code and the other is described in this article. So, which of the ways should I choose so that automatic updates still run for and apply to Nginx and its optional modules? Or should I create a cron job with a command/script specific for Nginx instead of using unattended-upgrades utility? Can I choose between volume updates and security-only updates to be automatically applied to the standard and optional modules? And finally, is there a possibility to automatically update Nginx's modules on the fly (without any connections having been dropped), like the documentation suggests it's possible with sudo kill -USR2 $( cat /run/nginx.pid ) P.S. Actually I'm not certain if unattended-upgrades utility would automatically update the standard modules in the first place, not enough time has passed since Nginx was installed to say for sure.

  • Completed downloads freeze Windows

    - by Ben Hooper
    The Issue Shortly after a file download via Google Chrome for Windows completes, the download will get stuck on "0 seconds left" and all other programs (except Google Chrome, for some reason, but browsing will not work) completely freezes into Windows' infamous "Not Responding" state, affecting Explorer particularly badly. Eventually, the programs will recover themselves but they will recover significantly faster if you cancel the file download, relative to how quickly you react. Performing the exact same operation immediately after cancelling the download usually works without issue. This issue occurs when with any file type (.ZIP, .MSI, .MSG, .PNG, .URL, etc) of any size from any source (Dropbox, SourceForge, Imgur, even tiny and locally-generated BLObs created by my own Chrome extension, etc) to any location.   Potential Causes As this issue is so inconsistent, I haven't been able to prove whether the issue is Chrome-specific or being caused by my system or my Chrome configuration but it's happening on both my work and home PCs. I originally suspected that this issue was being caused by security software scanning completed downloads for threats but I'm not as confident in that theory anymore as the issue persisted even after changing my security software from ESET NOD32 and Malwarebytes Anti-Malware Pro to ESET Endpoint to Microsoft Security Essentials.   System Information (of both PCs) Windows version: 7 Service Pack 1 64-bit Google Chrome version: 30.0.1599.101 (but has been happening for a long time)   Screenshots

  • Struggling with proper way to setup Permissions on Linux/Apache Web Server

    - by Dr. DOT
    Your expert experience and assistance is great, greatly appreciated here. I have been running a LAMP server for a long time, yet I still struggle with the best way to set file & directory permissions for FTP and WWW protocol activity. My Control panel is WHM/cPanel (not that it makes a difference), and out-of-the box: files are owned by the user account setup in WHM (eg, "abc") files have a group setting of "abc" as well file permissions are created with 644 directories are owned by "abc" directories have a group setting of "abc" directories permissions are created with 0755 Again, these are the default permission settings. Now everything is fine with FTP activity, but please advise me if any of these file/directory settings create issues, especially with security. Here's where my struggle comes into play. I have PHP apps that allow a visitor to create, edit, rename, delete, etc. sub-directories and files in certain selected directories. PHP runs as "nobody" on my server. So in order to get my PHP/Web apps to work, I have had to: chown nobody * chgrp nobody * chmod 0777 * to everything in these certain & selected sub-directories. I know this is probably a huge security whole (so don't ask me for any links :) but how should I set all the permissions to allow my FTP user to do his thing while allowing the PHP apps to do their thing will also "minimizing" any security risks and exposures? I know that big CMS systems like Drupal, Joomla, WordPress and so on, handle this. Thanks ahead of time for reading through this and offering your expert advice!

  • Why are my Windows 7 updates continuously failing?

    - by Chris C.
    I'm an advanced level user here with an odd issue. I have two Windows Updates that are failing to install, every single time. I'm getting a mysterious "Code 1" error on both updates, an error for which I'm having difficulty finding a solution.

  • Configuring PAM with pam_mount; getting a dlopen() with an HX_Init error

    - by Jamie
    I'm trying to get automounting upon login working on Ubuntu 10.03 Beta 2. I didn't find a package for pam_mount, so I ended downloading it and building it. This required: sudo apt-get install build-essential pkg-config libxml2-dev libssl-dev libpam-dev Additionally, the libHX-dev is required but as of yesterday (23/4/2010) the package version provided (3.2) wasn't up to snuff (3.4) so I downloaded, compiled and installed that too. cd ./pam_mount-1.36/ && ./configure && make && sudo make install When I tried it (pam_mount) I got this in my auth log: Apr 23 12:18:02 ubuntu sshd[1195]: PAM unable to dlopen(/lib/security/pam_mount.so): /lib/security/pam_mount.so: undefined symbol: HX_init Apr 23 12:18:02 ubuntu sshd[1195]: PAM adding faulty module: /lib/security/pam_mount.so Apr 23 12:18:06 ubuntu sshd[1195]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.20.182 user=jrisk Apr 23 12:18:06 ubuntu sshd[1195]: pam_winbind(sshd:auth): getting password (0x00000388) Apr 23 12:18:06 ubuntu sshd[1195]: pam_winbind(sshd:auth): pam_get_item returned a password Apr 23 12:18:06 ubuntu sshd[1195]: pam_winbind(sshd:auth): user 'jrisk' granted access Apr 23 12:18:06 ubuntu sshd[1195]: Accepted password for jrisk from 192.168.20.182 port 4369 ssh2 Apr 23 12:18:06 ubuntu sshd[1195]: pam_unix(sshd:session): session opened for user jrisk by (uid=0) What do I need to do get HX_Init into the system?

  • Access to CD/DVD Drive is Denied through Windows 7 Explorer (Permission Problem)

    - by Synetech inc.
    A while ago I started having trouble with my optical drives. Both of them keep showing up in Explorer as CD/DVD drives on boot, but as soon as I put a disc in either one, it suddenly turns into a hard-drive—“local disk” is displayed in the Type column, though the File System column remains UDF/CDFS. (I though that maybe it was a permission issue on the registry key in HKLM\System\CurrentControlSet..., but I’m not so certain because of the next test.) When I try to open a disc (of any type), I get an access denied error message. If I open an elevated command-prompt, I am able to access the files. Also, if I kill Explorer and run it from an elevated command-prompt (thus giving Explorer elevated permissions), then I can access the files from Explorer. I’ve tried uninstalling and reinstalling the devices without success. The security dialog indicates that there are none set for the drives (no owner and no permissions). I tried setting the owner, but am only able to do so if there is a disc in it (it complains if it is empty), but the settings do not stick (if I immediately open the security dialog after setting it, it is empty again). I tried setting permissions, but that gives an error. I’ve included a screencap-flowchart of the security dialog of one of the drives below. (Yes, I made sure that there are no upper- or lower-filters, and yes, I ran sfc. I also made sure that in the policy editor, “devices: restrict CD-ROM...” is not set.) Does anyone know what the owner and permissions are supposed to be for optical drives and how to reset them?

  • Read access to Active Directory property (uSNChanged)

    - by Tom Ligda
    I have an issue with read access to the uSNChanged property when doing LDAP searches. If I do an LDAP search with a user that is a member of the Domain Admins group (UserA), I can see the uSNChanged property for every user. The problem is that if I do an LDAP search with a user (UserB) that is not a member of the Domain Admins group, I can see the uSNChanged property for some users (UserGroupA) and not for some users (UserGroupB). When I look at the users in UserGroupA and compare them to the users in UserGroupB, I see a crucial difference in the "Security" tab. The users in UserGroupA have the "Include inheritable permissions from this object's parent" unchecked. The users in UserGroupB have that option checked. I also noticed that the users in UserGroupA are users that were created earlier. The users in UserGroupB are users created recently. It's difficult to quantify, but I estimate the border between creation time between the users in UserGroupA and UserGroupB is about 6 months ago. What can cause the user creation to default to having that security property checked as opposed to unchecked? A while back (maybe around 6 months ago?) I changed the domain functional level from Windows Server 2003 to Windows Server 2008 R2. Would that have had this effect? (I can't exactly downgrade the domain functional level to test it out.) Is this security property actually the cause of the issue with read access to the uSNChanged property on LDAP searches? It seems correlated, but I'm not sure about causation. What I want in the end is for all authenticated users to have read access to the uSNChanged property for all users when doing an LDAP search. I would also be OK if I could grant read access for that property to an AD group. Then I can control access by adding members to the group.

  • Cannot browse Visual SVN Repositories

    - by user1783560
    I went through Unable to browse repository after setting visual SVN Server and tried to implement the answer suggested but even the IP address is not solving my problem. I have 1) Turned off firewall 2) Set the directory C:\Program Files (x86)\VisualSVN Server security rights to "full control" for all groups including "Network service" group. 3) Set the directory D:\Repositories security rights to "full control" for most groups including "Network service" group. 4) Tried switching between secure and non-secure connection option in visual svn server manager. 5) Tried different with port numbers. Including 443 (with https) and 80 (http). Also tried giving random ports with/without https. Using computer name/ IP address in the url doesn't help. Windows network diagnostics - Troubleshooting report has following message for me. Security policy settings or firewall settings on this computer might be blocking the connection. = Detected Can someone guide me please? I have spent more than two weeks on this now without any solution. Thanks in advance! I appreciate your responses.
