Frequently Asked Questions
What is SLNet RF?
SLNet RF is a secure Telnet Server for Microsoft Windows 2000, 2003, and 2008.
What applications can SLNet RF run?
SLNet RF can run character-mode
applications: DOS text applications, Win32 console
applications, OS/2 character-based applications, and POSIX applications.
What applications can SLNet RF not run?
SLNet RF cannot run Windows based GUI applications. Any applications
that use a GUI will not run in SLNet RF. Some Win32 applications
create a second console window that is invisible to SLNet and
therefore SLNet RF will not be able to display their output.
At this time, the only applications that do this are GNU UNIX
ported utilities such as vi.
How much memory
does SLNet RF require?
SLNet RF requires one megabyte of system memory for the Service and
less than one megabyte of memory for each logged-on user, plus whatever
memory requirements the applications being run require.
The formula for determining how much memory is required is:
NT memory requirements + 2MB SLNet + (1MB x Number of users)
So for SLNet RF running on NT 4.0 Workstation to support
two users:
16MB (NT) + 1MB (SLNet) + 2 x (1MB) = 19MB
What terminal types does SLNet RF support?
SLNet RF supports VT100, VT220, and ANSI terminal types.
1000 others using Slcons, if using the multi-consoles option.
What is the maximum number of concurrent connections
I can make to my server?
As a general rule, the more CPU and RAM that you have on
your system the more connections you can make. The following
is a table that shows the approximate maximum number of connections
that SeattleLab has tested. The Operating System, CPU, and
RAM for each test are listed for reference.
* The Microsoft registry tweak involves changing a registry
value. Open the registry editor by clicking Start > Run and then typing
regedit then clicking OK, or by using RegShell shipped with SLNet RF.
Expand HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Session
Manager > SubSystems.
