I have a Ubuntu VM in the cloud - the display is ok but the it's not perfect. There is a 'lag' when moving windows which makes the movement a bit 'jerky' and difficult to follow. So what I need is for someone to go into the VM via VNC so that the display is fixed. Because I need to be able to replicate this I will also need instructions of the script or method that was used.

I Have an existing VoIP Server and need Technical help configuring settings and establishing new security protocols and DDNS Protocols I am needing someone who has knowledge of how to configure DDNS for the Linux Server IP Configurations as well as we are using a dynamic ip address.

So I have an account setup through and have it set to the router for Elastix access. Our Elastix system is about 2 years old now and has been working fine. - We have had issues regarding not being able to hear callers, being able to dial out and the caller will hear us, but we cannot hear them. Also we need to ensure that the account is setup correctly in the ifconfig-settings of the linux server as well. We can use Team Viewer for you to login and see settings and walk me through the settings as I need to see the work being completed. Please let me know as soon as you can work on this - I want to hire - NOW - and can meet up anytime for the tech support! Thanks for your time Aaron

I am receiving errors on our website when customer tries to purchase a product. We believe this is an issue related to a HTTPS canonicalization issue. Our previous server expert solved this same exact issue on year ago. These were his notes: "your server has CentOS 5.9 installed, so it doesn't support SNI, so there was a subdomain mess. I've just had to make some changes to webserver configuration so solve the issue" We are seeking professionals with server-side development experience who can help us with this issue. We also have some future ongoing back-end and front-end work in the future that we can give to you if you can help us out.
