The default temporary ban duration is 10 minutes.
The temporary ban thershold is configurable via LoginAttemptTempBanThreshold
in sbbs.ini and the ban duration is configurable via LoginAttemptTempBanDuration
(in seconds).

issues with files over 4GB.

before re-reading them.

xpms_add_chararray_list instead.  Prevents having to free string lists
in the sbbs.ini parsing code.

New Features:
- Multiple bindings for each service
  Use comma-separated interfaces on Interface= lines in the ini file.
  Default is now "0.0.0.0,::"
- IPv6 support
- TLS support for the webserver and (non-static) services
  New TLS option in services.ini (ie: Options=TLS)
- Decrease LEN_SCAN_CMD to 35 chars, increase the CID field to 45 chars,
  and rename the MAIL_CMD string to IPADDR.  I think this frees up the
  note field for SysOp use.

MinFileSize and MaxFileSize keys in the [ftp] section of the ctrl/sbbs.ini file
these values default to 0 which effectively applies no min/max to uploaded
files. Set MinFileSize to 11 to defeat the recent penetration testing seen
uploading 10 byte files with random filenames (8 alpha cars ending in ".txt")
with 8 alpha chars in the file, followed by a CRLF pair for a total size of 10
bytes.
Fixed bug whereby failed/aborted uploaded files would be left (not deleted).
Log errors when any file deletion fails in the FTP server.

clients, timeouts, etc.) into the various *srvr.h files and use them instead of
hard-coded constants sprinkled through-out the .c files.
If the web server "max_clients" key isn't specified in the sbbs.ini file,
use 0 (unlimited) for the max_clients value.

The attempt list can be view with sbbscon->'a' command or sbbsctrl->view->Login

Delay/throttle/hacklog/and auto-filter values/thresholds are now configurable
in sbbs.ini.

error counting/logging/messages to be handled by front-end (e.g. control panel)
regardless of log_level setting.
Mail server now filters blocked-subjects before applying DNSBL tag.
Received message header TO and FROM fields are no longer checked against the
email.can file for SMTP-authenticated clients.
SMTP MAIL FROM and RCTP TO addresses are no longer checked against the
email.can file for SMTP-authenticated clients.
Statistics are displayed in a more legible manner when the mail server is
terminated.
The msgs_received stats counter now includes blocked and ignored messages too.

startup option - we will *always* use the local timezone. If the sysop wants to
use GMT/UTC, they should configure their operating system accordingly.

instead of a bit-mask representing all the log levels to actually "see", use a
single numeric (or nmemonic) level value (ERROR, WARNING, NOTICE, etc.)
and less severe log levels (levels with a higher numeric value) will be filtered
(e.g. not "seen" or logged). It's the basic syslog() concept.

(enabled by adding LOOKUP_PASV_IP to the "Options" value in the [ftp] section
of your ctrl/sbbs.ini.
This option tells the FTP server to perform a hostname lookup (on the BBS's
hostname) to determine the correct/current public IP address to use in
PASV responses. This is one more kludge to work around stupid NAT devices
(consumer firewalls/routers).

(for broken firewall/NAT devices) and PASV port ranges (default is 1024-65535).

Created sbbs_read_js_settings() and sbbs_set_js_settings() to read and write
all settings to/from .ini files in a modular fashion.
This is a precursor to implementing support for JavaScriptThreadStack (limit)
support for all JS-enabled servers and services (working around the ircd bug).

Added shutdown_now to startup structures, used for nice shutdowns
(when server isn't in use) as opposed to terminate, which is immediate.
shutdown semaphores files are only acted on when server not in use.

by BindRetrycount and BindRetryDelay keys in the ini file.

Will control the number of times/delay between attempted calls to bind()
before the thread packs up and goes home.

STARTUP_INI_BITDESC_TABLES is #defined. These tables (even though declared
"static") were being compiled for every .obj and linked (multiply) into each
binary (possibly causing new segfaults in BSD builds?).
Init field tables are similarly only defined if STARTUP_INIT_FIELD_TABLES is
#defined.

(soon to be removed) to ftpsrvr.h.
Defined ftp_init_fields[] and FTP_INIT_OPTS to specify elements
(and bits) that require server recycle when changed.

is used by sbbscon to re-load the relevent portion of the startup .ini file
when a server is recycled, allowing dynamic changes to sbbs.ini.

of log entries reach the system (NT event) log.

function prototypes (currently using LOG_INFO level for all).

recycling without using semaphore files.

back to callback functions (e.g. lputs, thread_up, etc). This allows servers
to share the same callback functions, eliminating many nearly-identical
functions. This was able to shave quite a bit of redundant code from ntsvcs.c.
This feature is not utilized in sbbs (sbbscon.c) or sbbsctrl (mainformunit.cpp).

If you are not running your BBS as root, update and recompile now.

NOTE: Remember, RH9 users using the new threads - the default should use
gmake THREADS_ACTUALLY_WORK=1

Added semaphore file check frequency (sem_chk_freq) element to all server
startup structures (previously hard-coded to 2 seconds in most cases), defaults
to 5 seconds.
New SemFileCheckFrequency value in .ini file (both global and per-server).
