Checkpoint Firewall FTP issues - 'quote password' or Account command ('ACCT')

I usually post stuff about Cisco, but recently I got exposure to Checkpoint so I am adding Checkpoint to my library. I am currently working on a 3 part series on "how-to" install virtual Checkpoint Firewalls on a Linux KVM hypervisor. A quick search on Google reveals 0 posts related to this, so mine might be the first "how-to" on this topic. Stay tuned for more Checkpoint related posts in the near future.

Here is my first post on Checkpoint regarding the FTP issue "Wrong username or password". I will try to keep it short!!  

Trying to FTP from command prompt on a windows machine.

 Command line ftp:  
 ftp ###.###.###.###  
 Connected to ###.###.###.### (###.###.###.###).  
 220 Check Point FireWall-1 Secure FTP server running on XXXXXX  
 Name (###.###.###.###:XXXXX): usernamejoe  
 331 password: you can use password@password  
 Password:  
 200 password: you can use 'quote password' or Account command ('ACCT')  
 ftp> pass  
 Passive mode off.  
 ftp> ls  
 421-Access denied - wrong user name or password

Cisco Nexus ERROR MSG - SFP Validation Failed

I came across the other day when I was bringing up a new connection on a Cisco 3548 Nexus.

"SFP validation failed"

This happens when the speed is set on an interface and the SFP does not support it. To fix it get into interface config mode and type.

 switchport host
 shut
 no speed
 no duplex
 no shut

Cannot SSH into ASA - ssh_exchange_identification: Connection closed by remote host

I usually write quiet a bit but I figured I would keep track of these small error messages also. So here it goes .. last week I ran across an issue on one of the ASAs. Here is the error message.

"ssh_exchange_identification: Connection closed by remote host"

How to fix it?

Telnet or console into the ASA and type this in the global config mode.

ASA(config)#crypto key generate rsa modules 1024

Save the config (wr).

That should resolve your issue.
