• Constant prompts for credentials from one Mac Outlook 2011 client

  - by Top__Hat

  The majority of my Exchange users are all on Windows 7 and have no issues (at least using Outlook...) but a subset of the executives are ardent Mac users running Outlook 2011 for OS X. One of these clients is prompted every 5-10 minutes for credentials. Ticking the checkbox to remember credentials does not fix the situation. Mac version is 10.7.2. I have already removed and rebuilt the EWS virtual directory on my Client Access server. Outlook anywhere is set to NTLM authentication. None of the Microsoft clients are experiencing this issue. What else can I do to make this issue go away?

• LDAP loginShell on platforms with different paths

  - by neoice

  I'm using LDAP to deal with users and authentication across my network. I'm now adding FreeBSD hosts and have hit a problem with login shells. on Linux, shells tend to be in /bin/$shellname, so setting my login shell in LDAP to /bin/zsh works perfectly. on FreeBSD, /bin/zsh doesnt exist, I need to use /usr/local/bin/zsh. is there a solution to this? I imagine I might be able to make some sort of login-shell.sh script that LDAP passes out as the "shell" and then use the script to determine the actual shell for the user, but I'm not a fan of that idea. I'm using Debian and FreeBSD, both with a standard OpenLDAP/PAM/nss setup. edit: it looks like using /bin/sh and adding an exec $shell to .profile would "work", but that doesnt scale very well.

  - by Steve

  I am trying to submit a post on www.technicalhelp.de, but I receive an error: Invalid Session. Please resubmit the form.

• Does nginx auth_basic work over HTTPS?

  - by monde_

  I've been trying to setup a password protected directory in a SSL website as follows: /etc/nginx/sites-available/default server { listen 443: ssl on; ssl_certificate /usr/certs/server.crt; ssl_certificate_key /usr/certs/server.key; server_name server1.example.com; root /var/www/example.com/htdocs/; index index.html; location /secure/ { auth_basic "Restricted"; auth_basic_user_file /var/www/example.com/.htpasswd; } } The problem is when I try to access the URL https://server1.example.com/secure/, I get a "404: Not Found" error page. My error.log shows the following error: 011/11/26 03:09:06 [error] 10913#0: *1 no user/password was provided for basic authentication, client: 192.168.0.24, server: server1.example.com, request: "GET /secure/ HTTP/1.1", host: "server1.example.com" However, I was able to setup password protected directories for a normal HTTP virtual host without any problems. Is it a problem with the config or something else?

• How do I configure SSH on OS X?

  - by cwd

  I'm trying to SSH from one Mac running OS X 10.6 to another. Seems to work fine via a password, but I can't get it to use a RSA key instead. Where is the ssh configuration file on OS X and what is the command to reload SSH? Update What I'm asking is how to configured advanced options. For example, on Ubuntu there is a ssh config file at /etc/ssh/sshd_config and if you do something like change the port or disable password authentication for a particular user (PasswordAuthentication no) you need to run /etc/init.d/ssh reload to reload the config. I didn't see that file on OS X, so was just wondering where it was. I am aware of the ~/.ssh ~/.ssh/authorized_keys and `~/.ssh/config

• SSH Tunnel doesn't work in China

  - by Martin

  Last year I was working in China for a few months. I never bothered setting up a real VPN, but just created a SSH tunnel, and changed my browsers proxy settings to connect through it. Everything worked great (except flash of course) but that was fine. However, now I'm back in China but I'm having problems with this approach. I do the same thing as last time, and according to https://ipcheckit.com/ my IP address is indeed the IP of my (private) server in the US, and I'm logging in to my server using a fingerprint I created long before going to China so no MITM should be possible. Furthermore the certificate from ipcheckit.com is from GeoTrust - so everything should be OK However, I still can't access sites which are blocked in China. Any idea how this could be possible?

• Amazon S3: allow users to upload on a restricted basis (per bucket maybe)?

  - by Tom

  Hi there, I'm thinking about signing up to the Amazon S3 storage service. What I want to do is create a service where other people can register their own bucket with a certain amount of storage. These users will install my software, which then uploads their files. Of course, the users may only upload what they have paid for. For this to work I would like to create a separate bucket for each customer, each with its own properties. Question 1: is this possible with the API? How? This means that the installed software must have the rights needed to upload to my Amazon S3 account. Question 2: can I create individual authentication IDs for each bucket or customer, so that they can only upload with restrictions I have set? Thanks in advance.

• ConfigurationErrorsException when serving images via UNC on IIS6

  - by Mark Richman

  I have a virtual directory in my web app which connects to a Samba share via UNC. I can browse the files via Windows Explorer without issue, but my web app throws a yellow screen with the following message: Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately. Parser Error Message: An error occurred loading a configuration file: Could not find file '\cluster\cms\qa-images\120400\web.config'. What makes no sense to me is why it's looking for a web.config in that location. I know it's not an authentication issue because the virtual directory can serve images from its root (i.e. \cluster\cms\qa-images\test.jpg serves as http://myserver/upload/test.jpg just fine).

• AD Local Admins without password sharing

  - by Cocoabean

  My team is building out an Active Directory environment in a small grad school with support for general computer labs, and staff/faculty machine and account management. We have a team of student consultants that are hired to do general help desk work. As of now we have a local admin account on every machine. It has the same password and all of us know it. I know it's not best practice and I want to avoid this with the new setup. We want to have local admin accounts in case there are network issues that prevent AD authentication, but we do not want this account to be generic with a shared password. Is there a way we can get each machine to cache the necessary information to authenticate a group of local admins so that if AD is somehow inaccessible, student consultants can still login with their AD admin accounts?

• Domain account credentials fails to start scheduled tasks

  - by neoco

  I have 2 Windows 2000 servers in a domain 'DC', which run numerous windows scheduled tasks under the 'DC\Task-User' account. These tasks are and have been running successfully in the past couple of years without any account/password modifications. Yesterday, the tasks went to 'Could not start' status. Myself having an admin account, was able to run these tasks with my credentials. Today, I ran the tasks again under the DC\Task-User account and they seem to be running fine without any issues. This has happened in the past too. I'm not into networking so don't know much about the underlying problem. Has this something to do with a Domain controller account authentication? Any pointers will be great!

• Software for Company internal Website [closed]

  - by LordT

  hope this is the right stackexchange site to ask this: We've a group of webpages/services at work (SE Startup), ranging from SVN, trac, continous integration to link collections to a DMS. Nearly everything has an RSS Feed to get the info I need, with the exception of SVN. I'm looking for some kind of software that can integrate these well on a kind of start-page. The most recent changes, upcoming events etc should be clearly visible, as well as an option to search (the search will be provided from a different tool). A news area should be included as well. Currently, I'm pondering doing this with either wordpress or TWiki, although wordpress seems to be the simpler solution in terms of getting something good looking quickly. Authentication should be handled by HTTP-Basic Auth, which we already have in place and working well. I normally would consider Sharepoint a viable option for this, but we're exclusively mac and linux, I won't put up a windows server just for this.

• ssh asks for password despite ssh-copy-id

  - by Aliud Alius

  I've been using public key authentication on a remote server for some time now for remote shell use as well as for sshfs mounts. After forcing a umount of my sshfs directory, I noticed that ssh began to prompt me for a password. I tried purging the remote .ssh/authorized_keys from any mention the local machine, and I cleaned the local machine from references to the remote machine. I then repeated my ssh-copy-id, it prompted me for a password, and returned normally. But lo and behold, when I ssh to the remote server I am still prompted for a password. I'm a little confused as to what the issue could be, any suggestions?

• IPv6 scope id issue with IE

  - by eych

  I have an ASP.NET website that works with Firefox because FF doesn't need the % in the scope-id to be encoded (%25). The website also works on the same machine using IE because I can leave out the scope-id. However, to access the website from another machine in the network, I need to add the scope-id to the IPv6 address. For some reason, using the scope-id doesn't allow an authentication cookie to be created, and the website keeps going back to the login page. Anyone using IE7+ to access an ASP.NET website on a network using IPv6 with an encoded %?

• What is your approach to draw a representation of your network ?

  - by Kartoch

  Hello, I'm looking to the community to see how people are drawing their networks, i.e. using symbols to represent complex topology. You can have hardware approach, where every hardware unit are represented. You can also have "entity" approach, where each "service" is shown. Both are interesting but it is difficult to have both on the same schema (but this is needed, especially using virtualization environment). Furthermore, it is difficult to have complex informations on such representation. For instance security parameters (encrypted link, need for authentication) or specific details (protocol type, ports, encapsulation). So my question is: where your are drawing a representation of your network, what is your approach ? Are you using methodology and/or specific softwares ? What is your recommendations for information to put (or not) ? How to deal with the complexity when the network becomes large and/or you want to put a lot of information on it ? Examples and links to good references will be appreciated.

• Tool to allow Kerberos Authenticated users to modify Firewall settings

  - by Lars Hanke

  I run a firewall on a central router. Recently, several users want to use Skype. Since firewalling Skype virtually means to switch the firewall off, I consider to allow users to temporarily punch holes for their system. Since the users have no accounts on the router, I consider using Kerberos for authentication and authorization. The router is a Debian Squeeze box, with minimal configuration, i.e. no web-server, database or similar gimmicks. Does anyone know an existing solution, which could be used for that purpose? Or does anybody know easy to use and well documented frameworks in say Perl, Python, C, C++, ... making the set-up of a Kerberos authenticated Client and Server application really simple?

• Forward Request to Multiple Servers

  - by cactuarz

  We have 2 servers. One is old server and another is the new one. Currently we about doing a migration because the old server is not capable enough to handle everyday requests. The specs are: Old server Ubuntu 10.04 Nginx as Reverse Proxy Apache WSGI Python/Django New Server Ubuntu 10.04 Nginx Gunicorn Python/Django Celery+Redis Our manager asked us to research if the old server can perform multiple forwarding to all incoming request, for example, set Nginx of old server to forward all request to both old and new server. The purpose is to perform unit testing to new server using old server as comparer, see if the new server is ready to take over the role. Please help, if there is an idea, or must install some engine, or what we do is impossible. Many thanks.

• Run 2008 R2 Service under 2000 Domain Account

  - by NoDisassemble

  I'm trying to get a service to run under a domain account. When I try to add the account, I get the error The account name is invalid or does not exist, or the password is invalid for the account name specified I know the account exists and the password is correct. I am also having trouble adding it manually to the "Log on as a service" setting, I get the error An extended error has occured. Failed to save Local Policy Database After a day of research I'm starting to suspect it has to do with it being a 2008 R2 server trying to use a 2000 domain account. I've tried to change the LAN Manager authentication level and the Minimum session security looks okay per my Google digging. I'm not sure what else I can do?

• rsync not using forwarded ssh credentials

  - by Mat

  I have a situation where I would like to rsync some files from a remote server to a server in my office. The source server requires key-based authentication and I have an appropriate key set up on my desktop machine. If I ssh into the local server and then ssh to the remote server, ssh agent forwarding works correctly. However, when I try to rsync over ssh I get permission denied. So, Desktop -- Local server -- Remote server. When ssh'd onto the local server ssh user@remote works, but rsync -avPe ssh user@remote:/src /dest does not - Permission denied (publickey).

• Problem with the hosts file under windows 7

  - by martani_net

  I updated some entries in the hosts file "C:\WINDOWS\System32\drivers\etc" to make google for example point to 127.0.0.1 # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost ::1 localhost 127.0.0.1 google.com This works fine under windows Vista, but not under Widows 7. When I type google, it goes directly to Google's website. For info, I am not using a proxy server. I think there are some temporary DNS settings that must be flushed, but I don't know how, anyone knows how to fix this? Thank you.

• How can an RSA key be placed in a "non-folder"?

  - by Phil

  I lack a lot of knowledge regarding the subject so please excuse me if my question is very ignorant. I just started out with RSA key authentication to my test-server. It did not work at the beginning and I tried and tried and re-tried to no avail. Then I realised, I was creating "mkdir ~/.ssh" and then "mkdir ~/.ssh/authorized_keys" before placing the id_rsa.pub into the latter folder, which did not work. My question is: How can id_rsa.pub be placed in "authorized_keys", which is not created by "mkdir" therefore not a folder? Thank you.

• Block all third party domains from web pages

  - by wizlb

  When I'm browsing the web, I'd like to not be tracked by any third party services like Facebook or Google. For instance, if I visit somepage.com I don't want my browser requesting things from facebook.com unless I allow it. However, if I visit facebook.com, Facebook still works. Does anyone know of a Chrome or Firefox extension that will allow me to do this? AdBlock in Chrome doesn't seem to work because it just hides the web page elements, it doesn't stop the browser from downloading them. I imagine that some kind of proxy/browser extension hybrid would be the best. Any suggestions? Thank you.

• Restrict only some plugins to specific sites in Google Chrome

  - by Christian

  I am looking for a way to set up Google Chrome so that it will run a certain plug-in (Java, what else?) only on whitelisted sites, but other plug-ins (like the PDF viewer) everywhere. From playing with the policies available for Chrome, I think there are basically two levels of plug-in management: List of disabled plugins/enabled plugins: Controls whether a plug-in exists for the browser at all This pair of policies applies to plug-ins, but not to sites. Default plug-in settings/Allow plug-ins on sites: Controls on which sites plug-ins can run This set of policies applies to sites, but not to individual plugins, and it cannot override the first pair. There appears to be no way to configure Chrome so that some plug-ins only run on whitelisted sites, but others run everywhere by default. I have also looked at filtering content on the firewall/proxy level, but I'm not convinced it can be done securely there. Filtering by URLs (file names) or content types can be circumvented trivially, and identification by content inspection cannot be safe either.
