Networking :: OpenVPN Openssl And OCSP To Make Sure Revoked Certificates Are Denied
Apr 6, 2010
I have openVPN working with a thirdparty CA, and validating UID entries from the client certificates in LDAP groups. My next step is to figure out OCSP to make sure revoked certificates are denied. I could dump out my CRL as a nightly job, but that of course presents a window where a revoked certificate is still valid. how to dump out client certificate back to pem format? For the ldap check all i was using was the DN, which doesn't really help me for openssl/ocsp
I run a web server on Fedora 12, principally using Apache, MySQL, and PHP. I host a variety of sites, one of which is a family website that contains semi-sensitive personal data for several hundred extended family members, who all have access to the database-driven site.
Until now, I have been using a self-signed SSL certificate to encrypt the data as it is read and written back and forth from my database. Family members have simply had to put up with clicking past certificate warnings as they enter the site, as most browsers flag self-signed certificates as bad. It hasn't really been that much of a bother, but I'd love to do it more professionally. I have looked into buying SSL certificates, but it's a site I host for free and would rather find a cheap or free alternative if possible.
So I'm just fishing for ideas to work with. What are some alternatives to using SSL certificates for moderately strong website encryption? So far, I run only one host on the domain, but may eventually need encryption that would support multiple hosts. Or does anybody know a way to make self-signed certificates work on most popular browsers without being flagged as suspicious?
Why is that certificates need to be revoked with openvpn?I simply removed them from the keys folder but everytime the client connects it just places the certificates back into the keys folder itself?! Should that be possible?
Secondly, I have a problems etting the revoke command.Is there a known setting on the openssl.cnf file that might cause this?
[root@server]# source ./vars NOTE: If you run ./clean-all, I will be doing a rm -rf on /etc/openvpn/easy-rsa/2.0/keys [root@server]# ./revoke-full client2 Using configuration from /etc/openvpn/easy-rsa/2.0/openssl.cnf error on line 282 of config file '/etc/openvpn/easy-rsa/2.0/openssl.cnf' 21368:error:0E065068:configuration file routines:STR_COPY:variable has no value:conf_def.c:629:line 282 code....
i am using red hat5 n i want to create X.509 certificates for ipsec vpn help me in creating certificates, not able 2 create certificates guide me ehere is the location for certificates.
I did some reading on Openvpn and am following some instructions I found @ Install & Configure OpenVPN SSL VPN in SUSE & openSUSE Linux | SUSE & openSUSE
I keep getting the same error message when I run the . ./vars command "NOTE: If you run ./clean-all, I will be doing a rm -rf on /etc/openvpn/easy-rsa/2.0/keys"
But when I run ../vars I get "Bash: ../vars: Permission denied"
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 am using Ubuntu 10.04-alternate-amd64 for full disk encryption. After getting my updates which i get as soon as they are released. I am getting the issue temp root (sudo) password is not being revoked. After using any app that requires the use of sudo the permission for it does not get removed like it normally does.
I have tried logging out then back in, which usually removes the permission, this no longer works, also tried waiting and even after 1 hour permission still there. The only work around I have found is to use the terminal to execute the required programs then after closing terminal the temp permission is now removed like it should be. This issue has effected all of my systems and a friend of mine as well, (friend uses same distro).
To replicate issue:
1) Boot system. 2) Login. 3) Check for updates or any other app that uses root permission. 4) Logout 5) Login 6) Repeat step 3 7) App will not ask for permission it will use root permission automatically.
Does anyone know how to configure an SSL cert with GoDaddy? On the following squid page it seems to use x509 and PEM format for everything. GoDaddy seems want CSR files to issue the cert. The x509 & PEM combo don't seem to generate these CSR files in the correct format. Does anyone know the openssl commands to generate the files and the config line(s) to put in squid.conf?
I started from this wiki: [URL] I also tried following this godaddy wiki, but it was for apache and not squid [URL]
I use openvpn to connect otherwise isolated machines, and use samba to share filesystems across the vpn, which works just fine.But I recently discovered that copying files using rsync -e ssh is so much faster than copying from a mounted filesystem - like about 5 times faster.I've got comp-lzo enabled in both server and the client, at least I think I have, the directive is there in both the server.conf and the client.conf files, but how do I check that it's active?Does anyone know if I can make openvpn behave more like rsync, because copying is easier than rsyncing?
I had installed openvpn in linux machine (public ip) remote pc.. and installed client openvpn in windows xp machine (local network )remote pc... ...how can i accesss openvpn server to access local lan network without performing NATING in firewall.
how can i make openvpn to access my entire office lan network through linux firewall. how can i allow remote client with (private ip)to access my entire ofice network through linux firewall
I am fairly clueless when it comes to open vpn configuration file. Though I should have some understanding to execute the fix if it is available.
I have a ovpn file that is created by my organization (so theoretically there should be nothing wrong with it) containing not only the typical connection information, but also my CA key, certerficate/Public and certificate/Private key. I was able to locate these keys using the standard text editors.
When I follow the procedure to import (Right click on Internet Icon --> Edit Connection --> VPN Tab --> Import) none of my keys were imported (perhaps the import is not complete). I think because of the import failure I was not able to click ok and create the connection.
Is there a method to get around this and get it working? I have been looking for existing solution online but I was not able to find any similar cases with mine.
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 ftp into the server and see the files, but when i try to make a directory or upload a file it returns an error saying that permission is denied.I am wanting the users to be able to log on with their user account and then be able to have full control over their directories. What can i do to fix this problem?I have enabled port forwarding for ftp. What else is there i can do? If you need any extra information, let me know! I would like to get this fixed asap!Here is my vsftpd.conf file.
# Example config file /etc/vsftpd.conf # # The default compiled in settings are fairly paranoid. This sample file
i just one to emulate the windows 2003 - windows XP easy VPN deployment, with my ubuntu server.I got my server side (ubuntu) and client side ( openVPN gui) and everything looks okbut now, i cant make a //server/SHARED and get from my house to the office's docs, despite the conection its ok... whats wrong?
I have been trying to set up openVPN on a Virtual Machine running Ubuntu 10.04 with the eventual intention of having a closed VPN in the workspace I'm at, and a bridged internet connection out through the server.My initial process/instinct was to go through Webmin. After a fair bit of tooling around making eys/certificates, I was able to get a response (and that's all it was, really) from my windows machine accessing the VPN server. However, in my attempt to bridge the network, I have lost all internet/networking capabilities from the server.Fortunately I am able to access the server directly from the hardware underneath (i.e. I don't need to SSH in or anything), and so I've been attempting to restore the server's networking back to default. I have returned the /etc/network/interfaces file to it's original state (just the loop, and an eth0 on dhcp) and restarted the networking. A check with ifconfig returns what seems to be a working eth0, and the loop (noting else) however I am unable to ping any outside server. When I do, I am given the message:From XXX.XXX.XXX.XXX icmp_seq=1 Destination Host Unreachable(where of course XXX is my IP address).nother VM on the server is able to access the internet just fine, so it's not the overall server hardware...I guess at this point I'm just trying to take steps back,
I have set up OpenVPN for my connection. I'm using this to connect to the internet from different locations using tunnelling.
Right now I have a few IP's : on eth0 I have IP from my ISP, on eth0:1 I have my own IP.I set up MASQUERADE to eth0 - but in this case when I try to access my restricted resources IP address from ISP is visible. What I want is to use my own IP address from eth0:1 - could somebody help me to build good working redirect entry for that? I want to redirect all connections to that IP assigned on eth0:1... - just to access Internet using my IP.
i've set up an openvpn server (with dhcp running on it) and i have to create compatible clients.the problem is how to get an ip by dhcp.with ubuntu i made a script like this
/sbin/ifconfig tap0 up /sbin/dhclient -e tap0
and everything works fine:tap0 goes up and then start a dhcp request to the server on tap0with fedora there is a nice problem i've noticed that is impossible to run dhclient later on a new interface because i receive this error "dhclient is already running".the tap0 goes up normally but i receive this error when i attempt to get an ip.is there a simple way to get an ip?if i try to kill or restart dhclient when the vpn tunnel is up,all'interfaces lost theirs ip and network goes down crashing my vpn...
Is there anyway you can configure either OpenVPN client or the system to allow connections using OpenVPN to be made to computers on the OpenVPN network using their alias rather than their IP address. This may sound blasphemous but you can in Windows. That is if the VPN network is say 10.x.0.x I could connect to Comp4 or Comp2 using Comp4 or Comp2 not 10.x.0. 4 or 10.x.0.2 or whatever IP is allocated by the OpenVPN server. If the OpenVPN server has not been restarted then it will usually allocate the same IP every time the same client connects.
I have access to a VPN I use when having confidential instant messaging sessions. For the purposes of my work, essentially.I'm a command line kind of guy, and like to use Finch (the shell version of Pidgin) for those.However, when I turn on my OpenVPN connection it routes all traffic through the VPN. Web-browsing, IMing, and I can no longer access other machines on my home network.Can I set OpenVPN to only route traffic I ask through that connection (either by port number or application, or some way I haven't thought of), while other traffic flows through my usual home network?Some kind of local proxy perhaps? Or a dd-wrt box set up as a proxy, connected to OpenVPN?I've played around with the GUI environment too (I have a basic GUI I sometimes use on my main machine) and have installed the full desktop 10.10 on a second machine just to see if I can work it out.
