I have noticed that on a new server with Centos 7.x it takes 30 seconds for a login prompt to pop up. I don't use keys - don't know how. Never tried with your application that I have owned for MANY years. I am still using version 6.28 just because there was no need to upgrade. We also had an issue that if trying the upgrade (at that time) it would not allow me to go back to the old version. I have other containers using Virtuozzo that don't have CentOS 7.x. It isn't a DNS issue. Hostnames resolve instantly as do IP's.
Staying on point -- does version 10.16 (?) use a different method to connect such as SSH 2? TLS or new handshake methods that I've not been accustomed to using? Times change and I've lived in a cancer hospital with a daughter for 11 years and I know that I am out-dated. My business is in shambles and I am starting over.
So what's the cause, if known, for slow connecting to a new server?
Bob,
It's a bit hard to debug a version that old. In some cases, if it's related to a bug that's already been fixed, the only option you have is to upgrade. But I'll tell you what...... I understand the pain you've been through with your daughter. I actually work at St. Jude Children's Research Hospital in Memphis, where we've been pushing survival rates for children like yours for over 50 years.
What I can do is *give* you the latest version (11). If that fixes the problem, we're golden! If not, we can begin to work through the possible issues. Later versions will actually give you more detailed information during the login process that we may be able to use to trace this down.
Download this and give it a try. It's actually still in BETA, so may give you some warnings about expiring, etc... Ignore those for now. Let me know your experience and we'll go from there.
