• Bacula Director and Storage in LAN

  - by B14D3

  I have two networks LAN and DMZ.. Machines in DMZ are accesible from internet ( only over http). In LAN I have servers that see all LAN and all DMZ machines but machinse from DMZ don't see any LAN servers. Machines in LAN have access only to all LAN and DMZ, no direct access to internet and no access from internet. DMZ <------ LAN DMZ ----X--->LAN I'm planning to configure Bacula as major backup system. My plan is to install Bacula Director and Storage deamon on the same server in LAN for safety reasons. So my question is: Will this configuration work, is it posible for bacula director and storage deamon installed on server in LAN to makes backup servers that are in my DMZ? Or in this network configuration Bacula should be in DMZ? (If yes will I can backup with it servers in LAN ?)

• Basic IIS7 permissions question

  - by Tom Gullen

  We have a website, with a file: www.example.com/apis/httpapi.asp This file is used by the site internally to make requests joining two systems on the website together (one is Classic ASP, the other ASP.net). However, we do not want the public to be able to access the file. In IIS7.5, is there a setting I can do to make this file internal only? I've tried rewriting the URL for it but this rewrite is also applied internally so the scripts stop working as they fetch the rewritten url. Thanks for any help!

• There are currently no logon servers available

  - by Ian Robinson

  I am running a Windows 7 laptop that is joined to my company's domain. When I installed Windows 7, I created an account for myself, joined to the domain, and it had been working quite well even though I'm physically remote most of the time, and not actually on the network. However, today I created a new local user account (non-admin) for my little brother. While he was using it, he decided he wanted to install a program, because his account is not an admin, he was prompted to enter Administrator credentials to allow the program to make changes to his computer. I entered my credentials, and this is the first time I ran into the error message: There are currently no logon servers available to service the logon request. I tried logging off and loggin back in, rebooting, etc etc, and no matter what, every time I try to authenticate as my "normal" domain account - I get that message. I can no longer access my computer as an administrator. I no longer know how to log in to my machine using any other account aside from my little brother's non-admin account. I don't have any other local accounts created, and the default local admin account was never enabled. I'd appreciate any ideas on how I can recover access to my account. Let me know if I can provide any more information. FYI - This is a similar question but not sure any of the answers help me in my case. http://serverfault.com/questions/71632/there-are-currently-no-logon-servers-available-to-service-the-logon-request

• Setting up Shibboleth to secure part of a website

  - by HorusKol

  I've installed the Shibboleth module for apache on Ubuntu 10.04 using aptitude to install libapache2-mod-shib2 as per https://groups.google.com/group/shibboleth-users/browse_thread/thread/9fca3b2af04d5ca8?pli=1 and enabled the module (I have checked in /etc/apache2/mods-enabled) I then proceeded to secure a directory on the server by placing a .htaccess file with the following directives: AuthType shibboleth ShibRequestSetting requireSession 1 Require valid-user Now - I haven't set up an SSL host yet - and I also haven't set up the IdP - but I would expect that the server would block access to this directory - but I'm getting the content without any problems. I have restarted the apache service and I have no errors in the log files.

• Recommend an SFTP solution for Windows (Server & Client) that integrates well with Dreamweaver

  - by aaandre

  Could you please recommend a secure FTP solution for updating files on a remote windows server from windows workstations? We would like to replace the FTP-based workflow with a secure FTP one. Windows Server 2003 on the remotely hosted webserver, WinXP on the workstations. We manage the files via Dreamweaver's built-in FTP. My understanding is Dreamweaver supports sFTP out of the box so I guess I am looking for a good sFTP server for Windows Server 2003. Ideally, that would not require cygwin. Ideally, the solution would use authentication based on the existing windows accounts and permissions. Thank you!

• How to close the logon process named NtLmSsp ?

  - by Aristos

  I have a windows 2003 server and time to time I am getting many login failures like this one. Logon Failure: Reason: Unknown user name or bad password User Name: administrator Domain: xx.xx.xx.xx Logon Type: 3 Logon Process: NtLmSsp Authentication Package: NTLM Workstation Name: XLHOST Caller User Name: - Caller Domain: - Caller Logon ID: - Caller Process ID: - Transited Services: - Source Network Address: 173.45.70.100 <- hacker Source Port: 4722 AND Logon attempt by: MICROSOFT_AUTHENTICATION_PACKAGE_V1_0 Logon account: user Source Workstation: XLHOST Error Code: 0xC0000064 The question is, how can I close this process of login ?, what I have left open and some one can try to login ? Some notes: I login to the server using tunneling, nothing is open except dns, email, and web ports, not even ftp, and all default ports are change and hidden. I also monitor port scan and capture any one that try to find the hidden ports. Probably it is something open... Thank you in advanced.

• How to handle user accounts for many sites running on same server

  - by Simon Courtenage

  Background to this question: I want to host multiple e-commerce sites on the same server, each with their own separate customer login application. Each site's login application needs to be secured by SSL. I'm unsure how best to handle this. For example, do I need to acquire a separate SSL certificate for each site (in which case, how do I do this dynamically, as the sites are created), or do I handle this using ONE login gateway-style application, which handles it on behalf of all the sites via a kind of transparent redirect? I'd be grateful for any pointers or advice. Thanks.

• Get the "source network address" in Event ID 529 audit entries on Windows XP

  - by Make it useful Keep it simple

  In windows server 2003 when an Event 529 (logon failure) occures with a logon type of 10 (remote logon), the source network IP address is recorded in the event log. On a windows XP machine, this (and some other details) are omitted. If a bot is trying a brute force over RDP (some of my XP machines are (and need to be) exposed with a public IP address), i cannot see the originating IP address so i don't know what to block (with a script i run every few minutes). The DC does not log this detail either when the logon attempt is to the client xp machine and the DC is only asked to authenticate the credentials. Any help getting this detail in the log would be appreciated.

• Google Chrome suspicious connections

  - by Poni

  I'm using Chrome at Windows and with TCPView (of the SysInternals freeware suit) I see that chrome.exe establish connections to these IPs: 173.194.37.104 209.85.146.138 Using http://www.ipaddresslocation.org/ I check about these IPs and see they're related to Google. Now, in order to clarify, these are the exact things I do: Open up chrome, the default page is set to BLANK (i.e no homepage whatsoever). Then I get into my website which has a blank page, so no "other" http requests are made. Right from this point there is a persistent connection, usually to '173.194.37.104'. What are these?? Very suspicious.. Edit #1: - I'm in 'incognito' mode right from start, when launching Chrome, using a shortcut with the '-incognito' switch. - I've turned off all phishing protections and other "advance" features in order to reduce Chrome's network activity.

• How do I disable administrator prompt in Windows 8?

  - by Arnold Zokas

  I am using Windows 8 Enterprise on my development machine. Most of the time, I need full administrator for debugging, changing system files, etc. In Windows 7, setting UAC to "never notify" would disable any administrator prompts. In Windows 8 this is no longer the case. Even with UAC disabled I get prompted to grant programs elevated privileges. Is there a way disable this behaviour? Note: I am fully aware of the repercussions. I have antivirus, firewall, etc and am generally quite careful about what I download or install on my machine.

• Has anyone had luck running 802.1x over ethernet using the stock Windows or other free supplicant?

  - by maxxpower

  I just wanted to see if anyone else has had luck implementing 802.1x over ethernet. So here's my basic setup. Switch sends out 3 eapol messages spaced out 5 seconds apart. if there's no response the machine gets put on a guest vlan with restricted access. If the machine is properly configured it will authenticate and be placed into a secure vlan. About 10% of my windows xp users are getting self assigned 169 addresses. I've used the Odyssey Access Client and it worked without a hitch. I'm using the setting to automatically use the users windows login to authenticate, but it's workign on 90% of the machines so I don't think that's the issue. Checking the logs on the dc it seems that the machines are trying to authenticate with computer credentials even though they are configured not to. I'm running Juniper switches with IAS for radius. I have radius configured for PEAP and MSvhapv2. Macs and linux boxes seem to have no issues authenticating. One last thing to add If I unplugging the ethernet cable and plug it back in usually resolves the issue, but I'd hardly call that acceptable for production. Kinda long winded and specific for a discussion, but just want to see if anyone else has had similar issues or experiences, or if anyone knows of a free XP supplicant that actually works with 802.1x over ethernet.

• Correctly setting up UFW on Ubuntu Server 10 LTS which has Nginx, FastCGI and MySQL?

  - by littlejim84

  Hello. I'm wanting to get my firewall on my new webserver to be as secure as it needs to be. After I did research for iptables, I came across UFW (Uncomplicated FireWall). This looks like a better way for me to setup a firewall on Ubuntu Server 10 LTS and seeing that it's part of the install, it seems to make sense. My server will have Nginx, FastCGI and MySQL on it. I also want to be allow SSH access (obviously). So I'm curious to know exactly how I should set up UFW and is there anything else I need to take into consideration? After doing research, I found an article that explains it this way: # turn on ufw ufw enable # log all activity (you'll be glad you have this later) ufw logging on # allow port 80 for tcp (web stuff) ufw allow 80/tcp # allow our ssh port ufw allow 5555 # deny everything else ufw default deny # open the ssh config file and edit the port number from 22 to 5555, ctrl-x to exit nano /etc/ssh/sshd_config # restart ssh (don't forget to ssh with port 5555, not 22 from now on) /etc/init.d/ssh reload This all seems to make sense to me. But is it all correct? I want to back this up with any other opinions or advice to ensure I do this right on my server. Many thanks!

• May the file size returned by stat be compromised?

  - by codeholic

  I want to make sure that nobody changed a file. In order to accomplish that, I want not only to check MD5 sum of the file, but also check its size, since as far as I understand this additional simple check can sophisticate falsification by several digits. May I trust the size that stat returns? I don't mean if changes were made to stat itself. I don't go that deep. But, for instance, may one compromise the file size that stat returns by hacking the directory file? Or by similar means, that do not require superuser privileges? It's Linux.

  How to run specific program with root privileges (Ubuntu OS) when no sudo user log into system? Program need root privileges to function correctly.

• Securing ColdFusion for internet facing server

  - by Goyuix

  What do I need to do to tighten down a ColdFusion server for internet facing apps? The only thing that specifically came to mind was to restrict the CFIDE and JRunScripts directories to a local subnet. Are there settings in the administrator I can tweak to make the applications more secure?

• Windows Server 2012 - SSL Cypher Suite Order Not Long Enough

  - by Sam

  I want to re-order the cypher suites on our new Windows Server 2012 box to help mitigate the BEAST vulnerability for our clients. I went to Local Group Policy => Computer Configuration => Administrative Templates => Network => SSL Configuration Settings, opened SSL Cypher Suite Order, enabled it, and copied the values from the SSL Cypher Suites textbox. I pasted them into notepad, re-ordered them, then copied+pasted them back into the SSL Cypher Suites textbox. However, the box isn't long enough to hold them all, despite the fact that the length didn't change. I would have to drop the last 3 cyphers (SSL_CK_DES_192_EDE3_CBC_WITH_MD5,TLS_RSA_WITH_NULL_SHA256,TLS_RSA_WITH_NULL_SHA) in order for it to fit. Should I just drop them? Other ideas?

• What are some good methods to improve personal password management?

  - by danilo

  I want to improve my personal password management. I usually use secure passwords, but overuse them for too many different places. My questions: What methods do you use to create passwords, e.g. for different online sites/logins? What methods do you use to remember those passwords? Memory? Pen&Paper? Software storage? Is there some good way to store my passwords somewhere, so I can always have access to them when I need them (e.g. a webbased solution on my own server) but at the same way keep them away from unwanted access? Edit: Someone on another site mentioned http://passwordmaker.org/. Have you had any good or bad experiences with that software?

• Protecting PHP packages on server

  Hi, I am a php developer and have recently decided to make one of my Magento extensions commercial. I have downloaded and configured MageParts CEM Server and that is all working perfectly in regard to licencing and delivery of module packages. The only issue is that the directory that the packages are stored in could be accessed by anyone. I tried this in a .htaccess file, but now it is not working. <Files services.wsdl> allow from all </Files> deny from all Clients are receiving a 403 Forbidden response. Have I done something wrong in the .htaccess file or would there be a better way to secure the directory? Any help would be greatly appreciated.

• PostgreSQL encrypted backups

  Is it possible to ensure that dumps taken from a PostgreSQL db are always encrypted? The data in the database is highly sensitive and we cannot afford un-authorized personnel, including Sys Admins who need to backup the db, to access the actual data.

• Prevent registry changes by users

  - by graf_ignotiev

  Background: I run a small computer lab of 10 computers using Windows 7 x64 Enterprise. Our users are set up as limited users. For additional restrictions, I set up local group policy for non-administrators using the microsoft management console. Problem: Recently, I found out that some of these restrictions had been removed. Reviewing the settings MMC and in ntuser.pol showed that the settings should still be in place. However, the related registry settings were missing in ntuser.dat. I already have registry editing disabled in the GPO (though not in silent mode). Question: What is the best way to deal with this situation? Should I look into preventing registry setting changes? Should I set up registry auditing to found out how these keys are getting changed in the first place? Or should I give up the ghost and write some kind of logon script that enforces registry values if they've been change? Any other ideas?

• Could local ISP capture my location whenever i launch a VPN to a VPN server?

  - by Ozgun Sunal

  I am extremely concerned that my ISP collects any information once I am connected to a VPN server. For instance, as far as I know, when I start a connection to a HotSpotShield VPN server, an IP address is assigned to me just before a successful connection. Besides, I'll be having an extra IP address at the beginning with the TAP Adapter. An encryption tunnel is set up between me and the VPN server. Whenever my request for a website reaches them (VPN server), they decrypt the data and later they encrypt the reply which returns from the web (targeted) server. This works like that. So, the ISP can not see what I am watching, displaying and writing because the connection is encrypted. But, the targeted websites see and record all actions. Still, they can not identify my real IP address. I'm really concerned about if the ISP can see "my location". OK, it has an IP address from another country as my real IP address, but how does my ISP detect the traffic going through them? Can they find out who I am? Won't they say "Hey, there is a traffic but who is and what he is doing right now?", because I get the Internet from them?

• Can I build a VPN on top of Tor?

  - by Thilo

  If I understand correctly, the Tor client works as a combination of a proxy server and application plugins (such as the Firefox Torbutton) that enable use of the proxy and contain additional application-specific privacy features (such as suppressing cookies, sandboxing JavaScript, turning off Flash). That works very well with applications that support it (such as Firefox). But is there a way to establish a VPN over Tor, so that my whole Wifi network can be protected, including applications that do not support proxy configuration and devices like iPod touches?
