After logging into a remote machine via SSH, what could cause terminal commands on the remote machine to not work?

I login to remote linux boxes via ssh to manage them. ssh [email protected]. They are only accessible when I'm logged into the VPN and are not accessible publicly.

Sometimes when I try to login, I am asked for my Password multiple times as it's not accepting the password, even though I know for a fact it's correct. After the 3rd attempt it will say, Permission denied, please try again at which point it lets me try 3 more times. After those failures it reads, Received disconnect from <internal ip> port 22:2: Too many authentication failures

If I restart my local computer, I can log in again (via the exact same command per history.)

When I get into the server no software installed commands are recognized. None of the commands are available via which either.

If I su - myname and provide my password ,I'm logged into my account again, and everything works - all commands found.

If I log out, then try to log back in, all of the commands work again without having to use su - . If I log out and log back in, commands disappear again, and I have to restart computer.

If IT logs in as me (from windows machine, either via su or directly with my L and P) they don't have any problems. They believe it's computer / terminal related.

Thoughts on why this is happening?

If it matters, Remote machine is CentOS 6 VMWare image. Local is Mac, and it happens from multiple Macs with various OSs.

You aren't getting warnings about "remote host identification changed", are you? Overwise, check the logs on the remote system, they should contain information about why your login attempts are failing.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
