This would be a global limit on tcp connections.

In Solaris 9 and above, the ftpd server is a version of the wu-ftpd server. So, yes, you can limit the number of users. Take a look at the man page for ftpaccess, which documents the command syntax for the /etc/ftpd/ftpaccess file. It is fairly complex, because it offers quite a lot of felxibility. Read particularly the section about the "limit" keyword.

what is the default tcp connection session limit for solaris 9 then?

Brian UtterbackPrinciple Software EngineerCommented:
If there is no class limit defined, then there is no limit. You are limited by the number of TCP connection. In Solaris, there is no global limit to the number of TCP connections. In Solaris 9, there is a practical limit based on the number of ephemeral ports available. In Solaris 9, that limit is 32,767. Also, since each connection requires a process to service it and some kernel memory to hold the data structures, there is also a resource limit, but the resources used are pretty small. You can easily get into the 10's of thousands of simultaneous connections.
