I have been happy with OpenVPN so far. But I have other issues.

Following is the situation right now : - OpenVPN server installed on Amazon Linux. - OpenVPN client installed on Windows 7. - Set up port forwarding and Masquerading as mentioned in the video on OpenVPN server. - Can establish VPN connection and RDP into all windows instances in the VPC without any problems.

Problems :

  • SSH over this OpenVPN connection doesn't work "properly". What I mean is, I can connect via SSH to a ubuntu instance in the VPC but after connecting when the shell pops up it shows me the date/time but I cannot type into the shell. The SFTP window which opens up on my SSH client also cannot list files.

  • MySQL connection doesn't work properly, I can establish a connection to the MySQL server in the VPC via MySQL workbench, but I cannot select the database and run a query, I can only 'see' the database.

What am I missing ?

The problems you mention are very odd. It doesn't seem like they would have anything to do with OpenVPN. You might need to fire up tcpdump/wireshark to figure out what is going on. –  Zoredache Apr 25 '13 at 23:03
    
Should I do that on my OpenVPN server or from the client machine I am connecting from ? –  LaWFuL EviL Apr 26 '13 at 0:42

Sounds like possible MTU issues: wandin.net/dotclear/index.php?post/2009/01/08/OpenVPN-MTU-Size –  fukawi2 Apr 26 '13 at 1:33
    
I'll definitely check out the MTU settings. But also, does this have anything to do with character encoding ? –  LaWFuL EviL Apr 26 '13 at 15:46
    
It was the MTU size. I first performed the mtutest from the client. Which gave me an answer of 1573, then I added "mssfix 1300" to the client size configuration and it solved the problem. –  LaWFuL EviL May 7 '13 at 14:52
