Programming :: Openvpn AUTH_FAILED And Remote Authentication Script?
May 22, 2011
Ive been trying to fix my openvpn remote authentication script. I managed to write a script for remote authentication using wordpress db as my base access details storage. However I cannot seem to get past AUTH-FAILED issue. Possible source of conflict might be my database query inside the script which returns nothing. Hope someone with enough knowledge of scripting and database querying can help me here.
here is my vpn_auth.sh:
Code: Code: #!/bin/bash
### Database Informations
DBUSER='dbuser'
DBPASS='dbpass'
Since yesterday I'm fighting with OpenVPN on Ubuntu 10.04TLS and I can not cope with the authorization of users from Windows 2008 AD server. It looks like this: Published 93.159.XX.XX IP address the router and all traffic directed to the internal LAN IP 10.0.1.210. Customers who will combine the different platforms are Mac OS, Linux, Windows XP, 7, Vista. The whole domain is for Windows 2008. Uploader authLDAP module, but I still can not connect, that is, not after entering the username and password from the W2K8 domain does not log
I've recently installed OpenVPN on my dedicated server (Fedora) in order to have full internet access for all of my WinXP clients. In case somebody is interested in the details of the OpenVPN installation, I followed this documentation: Rootserver-as-OpenVPN-Gateway. The installation runs quire nicely, I'm able to surf the net and even file-sharing programs work on the XP clients - at least to some extent. There is a slight problem though: the file-sharing programs complain that they have a "NAT problem" or that they are "Firewalled".
Most likely, this problem can be addressed by configuring remote port forwarding (RPF) on the server. The only routing rules which I've added on the server during the OpenVPN installation are these: Code: # initialize natting for openvpn iptables -t nat -F POSTROUTING echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -o eth0 -s 10.66.66.0/24 -j MASQUERADE Let's assume a certain application on a client is listening on e.g. port 1234. How do I configure RPF for this port on the server side.
I have OpenVPN 2.0.8 installed configured to Ethernet Bridge BR0. All windows outside machines can "see" and mount remote inside firewalled machines (i.e. \machine1 or [URL]). However I can't access to inside windows machines with windows Remote Desktop
I recently ran out of space with my free 2 GB U1 account. So I upgraded to a 20 GB pack.This was shortly after upgrading from 10.04 to 10.10, during which I changed the name of my computer from 'Rain' to 'El-Mustango'. Don't ask.Anyway, in the process of upgrading U1 to 20 GB, I noticed the machine I had connected on the website was still called Rain. So without really thinking, I removed it.Now I can't get U1 to sync. If it tries at all, it tells me that I've got no free space. And when I say "it tells me", I mean "someone should fix the bug where it pops up a notification for every single file it tries to sync".I've gone through every fix I can find online. My issue is the u1sdtool -s shows:Quote:

I have a openvpn server configured and users are using from remote location. I got some errors in the /var/log/messages file as:PHP Code:

My server is connected to the Internet for ssh on port 22 with root logon disabled, a single non-dictionary word user name allowed, and pki authentication only (about as secure as I can make it). I've previously run fc5 and 9 servers using the same sshd config since 2006 and had no security troubles, so I'm happy, but.. After the fc13 install and configuration, logins from a host on a remote network are taking about 1m 30s to complete! A (partial) console output for ssh -vv appears below. The lines marked with "**" were the lines after which significant pauses happen. This is fully repeatable.

Migrating whole Corporate Windows stations to Ubuntu which is a huge thing so I'd like to do it right and as painless as possible to users.
Here's how it's done now: Main server are already running Linux for years with DHCP, DNS, IMAP, Postgres and SAMBA.
Windows machines are part of Samba PDC and when user logs in, Windows connects to the user profile on Samba server. When user logs out and logs to another computer, he/she has the same files and settings. Basically, nothing is held on local stations.
All printers on the network are printers with network cards, so they are not attached to any computer. The right printer is set with cmd script when user logs in, which makes it possible to make other printer as default if one is faulty.
In my job we have 48 machines with Suse10 SP2 and they want all the machines to be able to authenticate to a unique server (something like a Radius Server or TACACS server), not doing the authentication locally. Do you have any idea on what to use and what needs to be change in the Suse Linux password auth for a remote server to be the auth server?
I try to get authentication working from remote LDAP server (Novell eDirectory)So far I can get correct info from id user or using ldapsearch (so the connectivity is there)But what do I need to configure to get authentication working for SSH login & vsftp login?
i have some problems with configuring openvpn tunnel connection to my openvpn server. I'm using static-key tcp connection. Network manager always said to me that connection could not be established. Also, when i try to run openvpn from terminal, i got some strange permissions problem:
Code:
openvpn --config config.ovpn Mon Apr 5 15:48:37 2010 OpenVPN 2.1_rc19 i486-pc-linux-gnu [SSL] [LZO2] [EPOLL] [PKCS11] built on Oct 13 2009 Mon Apr 5 15:48:37 2010 NOTE: OpenVPN 2.1 requires '--script-security 2' or higher to call user-defined scripts or executables Mon Apr 5 15:48:37 2010 /usr/sbin/openvpn-vulnkey -q moj.key
I want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.
So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.
Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.
Well, when I tried to change static IP to dynamic IP (changing '192.168.0.2' to '192.168.0.0/24') in the configuration file, the OpenVPN didn't work.
Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.
I hope I explained my problem as well.
My configuration file:
# OpenVPN Server Configuration File dev tun 0 ifconfig 192.168.0.1 192.168.0.2 cd /etc/openvpn secret key_file
In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (192.168.0.0/24, for example), instead of a static IP (192.168.0.2).I also thought to use a DHCP server, but I'm not sure that will work.
I am trying to ssh a remote box from putty but I am getting following error. "No supported authentication methods available" I don't have access to the server so I must have make my ssh client compatible to ssh server. This is the trace from another client

I'm writing some php code and part of it sending an email through smtp server, I used Mail.php from pear but unfortunately I didn't work since the smtp server is using NTLM authentication.Any alternates to Mail.php could solve this problem?
I'm trying to add HTTP authentication to my app (it's a rss reader). As the app is in written in C and uses Libxml2, I've been searching in Libxml2 doc, but it seems it's not possible. Maybe someone could point me to a link to relevant info about how I could achieve that?
I've got an asp page (I can't edit) which I can access with a test user I've setup, however when I try to access to same page via curl, I get the following error: Code: <h1> You are not authorized to view this page </h1>
The URL you attempted to reach has an ISAPI or CGI application installed that verifies user credentials before proceeding. This application cannot verify your credentials. There's lots of other text (doubt it's relevant though).
Here's the one liner I'm using: Code: curl -A "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)" -u myusername:mypassword [URL] I've done some searching but cant find anything which doesn't suggest rewriting the asp...
On Ubuntu server 10.10, with a relay smtp server with authentication via postfix; I keep getting 535: Incorrect authentication data. I'm sure my username and password is correct. Heres how I set up postfix: I created a file called smarthosts.conf in my /etc/postfix/ directory that contains the following:

my server uses plain text authentication on port 25. I would like to use security like SSL, but this particular server is unsecured.
If I am running a script, let's say a install script. Is there a way to make Su repeat authentication rather then just returning "Authentication failed" and continuing the script?
I need to make a choice on what authentication protocol I want to use for Authentication and Authorization. I was looking at Radius and then literature suggested that Diameter was a better protocol. Keep in mind I need this on a hetrogeneous setup ( linux & windows together). Diameter seemed like a good fit until I discovered that the open source code no longer seems to be maintained ( C/C++).
I was also looking at Kerberos as an option though there is alot overhead with the server. SSL/TLS or EAP? I am looking for simple but secure and am new at the security protocols.
I have a problem with ldap client authentication in ubuntu. I am using rhel5 as openldap server and I configured ubuntu as client, when I am trying to login the following message is coming."su: Authentication service cannot retrieve authentication info. Sorry" But when I do search through "ldapsearch" command output is coming without any errors, Can anybody explain what would be problem.
I have the need to SSH into a Slackware 12 box to provide remote support. I got this, but it doesn't provide for a real 2-way communication.
while : ; do read -p "Enter text to Local: " TXT ; DISPLAY=:0 Kdialog --inputbox "$TXT" ; done
So this loops and all, but it doesn't have a history and I have to wait for a return from the Local operator. If the operator has changed focus I can be waiting all day for a response and I would have to start another session to post a second comment.
What is nice is that it's small and I can create the .sh when I remote in.
-----Update since I started
I now have two scripts to take over from the first one. I have to have 4 SSH running to get this to work.
1 SSH to move(archive) and create a chat.txt; it also fires off a .sh that fires off a console that tails a chat.txt so the operator can see the chat history 2nd SSH to fire off a .sh that loops a Local kdialog input box that appends the chat.txt 3rd SSH to tail -f the chat.txt file on the remote so I can see the chat history 4th SSH to loop a read -p on the SSH so I can append the chat.txt
I'm writing something which takes user input (which may or may not contain spaces...) and then runs a command on a remote system via ssh. However the remote command does not work. I can't print the exact code so I'll just provide an equivelenat problem. This needs to work with filenames which do and do not contain spaces.
I have the following command that works Code: ssh root{at}IPADDRESS 'vim-cmd vmsvc/power.getstate 64 | grep Powered | awk "{ print $2}"' Which outputs the following text:- Powered on I would like to Append some text so the output is:- Ubuntu Server: Powered on Every different variation that I have tried ends up in an unexpected token.
i have made a java web server which works on localhost.but now i want to capable it handling many clients at a time.so clients running on different computer need machine name or IP address of server computer.How can i do this in java?
I want to run the scripts on remote system using plink. Here I am using pipes concept .I created two pipes And I want to handle the output and error in two different files. If host key (available in /.putty/sshhostkeys file) is not available or is not match then we will get "Store key in cache? (y/n)" message from child process into error file. If parent process reads this message then we will send "yes" if not then we will continue to next step and parent process will wait until exit child process .
In this bug case, host key did not match and response came late from child process into error file and parent process took it as host key already available and waiting for exit status of child process using waitpid(). But here "yes" did not send for running commands and exit the child process.Hence it is hanged at waitpid(). Please help me how to solve this issue.
