Proxy+'s change log

Proxy+'s change log

Version 3.00 #232 04.22.2002

FTP/HTTP Proxy

a new type of FTP server listing added. It means the FTP Proxy is able to access some new FTP servers which generate rarely used listing types.

WWW Admin

solved bug which caused the Proxy Settings/Alarms/General didn't store new settings.

Plugins

StopAttach plugin default configuration didn't include the 'EXE' extension.

Version 3.00 #230 04.05.2002 (all changes since #206 are listed here)

General

regular expression evaluator supports new metacharacters \b a \B (word boundary).
the function which does string substitution using regular expressions has been changed. The function replaces all regular expression matches in the source string (the older one replaced only the first expression match).
now 'WinXP' string is displayed in the Status WWW Admin page Info instead of 'Whistler' if the Proxy+ is running on the Windows XP.
solved bug with search mask evaluation. The bug caused that '*xxx' was found in the middle of string (URL) not at the end of the string only.
a menu which you can open using Proxy+ system tray icon is positioned to the current mouse position.
solved problem with time ranges. The evaluation failed when a time range has been defined by 'start_time-end_time' and the end_time was lower than start_time (20:00-05:00 for example) - it means the interval should end next day.
a bug was fixed which caused an exception has been logged into ErrLog.TXT logfile (exception in LogAccess function). The problem occurred seldom during Proxy start.

Plugins

New plugin support added.
solved an internal problem with table of exported plugin API functions.
New MPP plugin added. It's an universal (Multi Purpose Plugin) you can configure by writing a script.
New Alarm support added
New it is possible to store infected or dangerous messages into a file. Both the antivirus checking and filtering of messages support it.
New plugin for NOD32 virus scanner (http://www.eset.com).
New plugin for AVG6 virus scanner (http://www.grisoft.com).
New filtering StopAttach plugin.
New a new option allows to configure the Proxy to treat all message parts as dangerous (by default parts which can contain some dangerous code are checked only for performance reasons).

Mail subsystem

when a problem occurs (it is not possible to connect to remote POP3 server for example) the POP3 downloader writes POP3 server hostname, IP and port into MailLog.TXT log file.
New message filtering support added (using plugins)
there is a possibility to change the default extension of files which the copies of messages are stored into. It is accessible only by changing a Windows registry option value using regedit.exe utility: HKEY_LOCAL_MACHINE\Software\Fortech\ProxyPlus\Mail\CopyExtension (string type).
solved a bug in the POP3 server service which caused an exception was reported in ErrLog.TXT logfile when a POP3 client tried to download messages during Proxy+ restart.
message parser (it is used when a message is checked for viruses, for example) supports messages which uses wrong line termination characters (CR or LF instead of CRLF).
message parser supports some new non-standard UUEncoded attachment definitions.
message parser now tries to decode national names of attached files.
POP3 downloader built-in limit, which doesn't allow to read more than 100 remote POP3 mailboxes has been increased (200 is the current limit).
solved bug with parsing messages sent by some variants of BadTrans virus (base64 lines which are not aligned to the proper size).
solved problem with parsing message header when the continuation lines are not started by ' ' or #9 (Tab) characters. Because some mail
clients (Outlook Express) are able to parse such headers "properly" we must do it too.
POP3 Downloader records which were configured as "Completely disabled" were not ignored when P+ evaluated local emails.
max size of POP3 Account (POP3 Downloader) item increased to 100 (was 40).
when configured limit of max number of recipients per message (infinite by default) is reached new error code 452 is generated. Older specification of the SMTP protocol required 552 to be sent as an error response.
! solved problem with parsing messages sent by ALIZ and BadTrans viruses solved bugs which caused a message sent to sender of infected message couldn't be delivered sometimes.
POP3 mapped links support Netscape Messenger too (it is sending AUTH instead USER as the first command).
fixed: SMTP server didn't accept empty sender address.
calculation of total queued messages size fixed.
solved bug which caused messages with low priority have not been delivered in configured time interval. The same problem occurred when the message is larger then configured size limit.
when Proxy+ delivered an "undeliverable message" report then the original message has not been deleted from the outgoing queue in some cases.

WWW Admin interface

RegExp helper shows multiple regular expression matches now.
WWW Admin interface checks whether browser sent an extra characters into communication channel. If it did, these characters are removed before the channel is closed.
This problem could cause troubles with accessing (saving) WWW Admin options ("connection reset" error reported by Internet Explorer).
it was not possible to remove 0.0.0.0 IP address from the list of IPs (the IP has been displayed as 'All' improperly).
the Proxy+ Help contains description of all the new options.
the menu with Plugin related configuration items contains a link to
Proxy Settings too.
New all WWW admin forms use POST method to send your options to Proxy+. It means the options and values are not added to the Admin page URL. It solves problems with large list of options like ACL rules or so.
New WWW Admin interface supports CSS (cascading styles and sheets).
It is possible to change Admin interface look by changing external CSS
definition (stored in file Admin/admin.css).
New it is possible to display cached object details (including name of the disc file).
New it is possible to search for objects in the cache.
New it is possible to delete objects from the cache.
some options which disallow storing of some HTTP objects into cache changed theirs default values.

HTTP Proxy

The Proxy+ checks whether browser or server sent an extra characters into HTTP Proxy communication channels. If they did, these characters are
removed before the channel is closed. It looks like this problem could cause images were not displayed on downloaded pages for example.
some new non-standard date time formats (in the HTTP header responses) supported.
! there was a bug in #222 which caused the HTTP objects were not cached properly. Objects with defined size (valid Content-Length
in the header) has not been cached. Other HTTP objects were truncated (start of the file missing).
cached HTTP objects which have got cookie defined (Set-Cookie header field present) are handled differently. If there is Cache-Control: no-cache="Set-Cookie" header field present too then the cookie is newer sent to the browser from the cache.
Cache-Control: HTTP object directive is handled more properly. Proxy+ recognizes more arguments of that directive now.
cached object access algorithm has been completely rewritten (internal change - it has no influence to stored objects content).
older versions of Proxy+ have been sending HTTP request header and request body in two separate blocks (it doesn't matter on TCP stream connection). But we discovered some WWW servers and browsers expect the request header must be followed by at least of one byte of request body. In other case these WWW servers/clients abort the connections. It is wrong assumption because the TCP transport system can split large blocks into smaller ones or small blocks can be combined into a bigger one. Trying to solve this problem (caused by someone who programmed the WWW server or script running on it) this new release of Proxy sends request body together with the request header (if there is a free space in the buffer, of course).
It should solve problems with some login forms (HTML forms handled by POST actions) and it can solve some problems with missing pictures, probably.

Mapped Links

New A new option appeared in the Mapped Link WWW Admin page which allows you to instruct the Proxy+ that the security will not be checked on the link.

FTP Gateway

some bugs solved.
more details is logged when FTP Gateway debugging messages are enabled.
FTP Gateway has been rewritten completely. It supports passive transfer mode (PASV), several new types of communication with FTP clients (OPEN, SITE, PROXY OPEN, SITE OPEN) and there is a possibility to require authentication on the FTP gateway users against local user database.

SOCKS server

some changes in the SOCKS session initiation occurred. Proxy+ uses a different method to check the list of authentication methods offered by a client. Some SOCKS clients (ICQ for example) had strange problems (rarely) so the Proxy+'s SOCKS server includes a workaround for them now.

Real Audio proxy

more detailed debugging messages.

Security

Interface ACL Object didn't work properly when it was used to check the incoming interface of internal WWW server request.

Version 2.50 #206 07.25.2001

General

solved bug which caused the line traffic graph has not been displayed on the Proxy+ main window.
maximum number of allowed groups changed from 40 to 100.

WWW Admin

a group can be used as Proxy+ administrator now.
New it is possible to force Proxy+ to request authorization for all WWW Admin pages.
FTP cache settings (FTP directories and FTP files) used different default values than the FTP cache engine used. As a result it seemed the settings are disabled but in the fact they were switched on (until you saved the WWW Admin page settings to override the default values).
there were a bug in the sorting ruleset definition WWW Admin page which caused the 'Operation' box has not been displayed in Netscape browsers (at least 4.x version of the browser didn't show the box).

Mail subsystem

the outgoing queue management has been changed again. Each message has got its own state file (*.sta) which holds some useful information about the message.
The most significant change is the list of the recipient of the message has been moved into the state file (older version of Proxy+ held the list in the message itself).
New message loop detection. Now Proxy+ is able to detect when a received message is sent back to the internet and then downloaded again. Such messages are not forwarded.
POP3 Downloader removed spaces which you have defined inside the name of the remote POP3 account. Now trailing spaces are removed only.
there were a bug in the POP3 Downloader which could cause the message is damaged during download (problem with leading dots).
some error messages were reported to Proxy+ administrator. Now the problems are reported to the 'Mail\General\Trouble report to' output.
New POP3 Downloader allows to disable the POP3 record fully (to force the Proxy+ to don't include record's associated Email address to list of known local email addresses)
POP3 server writes down the number of messages and their total size when an user logs in/out.

WWW Server

solved problems with Access List (username/password authorization problem).

SOCKS

New it is possible to disable the SOCKS4 protocol (SOCKS5 not affected by the setting).

Version 2.50 #204 5.31.2001

Installation

there was a bug which caused the installation utility didn't work properly in some cases.

Mail subsystem

bug solved which caused that sent messages couldn't be deleted from outgoing queue in some cases (rarely). The bug occurred when the communication with remote SMTP server was broken near the end of the message.

Cascading

bug solved which caused username/password pair was not sent properly to parent proxy server. The Proxy+ didn't work properly if the parent proxy server required authorization.

Version 2.50 #202 5.11.2001

General

! an obscure GDI resource eating bug solved. On some installations of Windows (especially Win9x and WinME) Proxy+ caused the system resources went down and the Windows was not able to display application's windows properly.
New support for regular expressions added. Almost settings which allowed to use wild-card patterns allow to use regular expressions too.
New WWW Admin interface supports Edit feature. Some complicated settings (like Mail\POP3 Download) can be changed and updated easily now.
New Proxy+ will not terminate after a user logs off (on the Windows 9x system). See the 'When windows user logs off' option on the Administrator\Additional WWW Admin page.
A new Content-Type added to the ContentType.txt file: application/x-javascript JS
installation utility was completely rewritten. Now the archive is much shorter (approximately 200kB saved) because a better compression algorithm is used.
uninstaller was rewritten.
service mode detection routine changed. Now Proxy+ starts (in application mode) even the logged on user has not enough rights to fully access Windows NT/2000 services.

Cache

when an object is being added into the cache, Proxy+ checks whether there is any setting which doesn't allow to add the object into the cache (Disabled By Name for example)

DNS Forwarder

a bug which caused the DNS forwarder was not able to recognize a packet as a DNS server response was solved. The problem occurred when
the DNS server cleared RA (Recursion Available) flag in the response. Some DNS servers (it depends on the server configuration) sends responses which were not recognized by older versions of Proxy+ as valid responses.

DNS cache
New it is possible to change internal DNS cache settings.
All DNS related error codes are cached negatively now (formerly the 11001 code was cached only)

Mail server

New POP3 Downloader allows to leave messages on the server
New POP3 Downloader supports POP3 restrictions rulesets
New it is possible to configure Proxy+ to send a notification when a mailbox reaches preset size.
when an error occurs during POP3 Downloader session Proxy+ continues to download mailboxes for rest POP3 Download records (former versions of Proxy+ terminated the POP3 Downloader session).
New it is possible to enable/disable downloading of messages from ISP's POP3 servers using one checkbox.
New it is possible to enable/disable each record in the Mail\POP3 Download independently.
New POP3 Downloader supports APOP authentication (no plain text password is sent over the Internet to the POP3 server)
Mail\Valid Time Intervals checkboxes are checked by default (no time restriction active by default).
POP3 Server calculates UIDL identification of a message on demand (when a client requests the identification). It significantly decreases the time which the locking of user mailbox takes if there is a large amount of messages in the mailbox.
POP3 Downloader adds X-PPRemoteMessageNumber header field into all downloaded messages. The field contains the message number in the remote POP3 server mailbox.
A solution for MS Outlook Express 'Date:' field vulnerability implemented. Proxy+ detects strange 'Date:' fields in messages and replaces the bad field value with new one.
When sending messages to the parent SMTP server Proxy+ sends a RSET command after a first message (if more then one message has to be sent).
When a SMTP authentication is used Proxy+ sends an EHLO command again (after successful authentication).
Returned messages (messages created by mail server) contain 'Date:' field now. And Date/time fields use local time representation now.
New outgoing queue engine was rewritten. Now thee queue status is hold in the RAM and it is reloaded only when the queue changes. It means that disc is not accessed until a change occurs.
New outgoing queue engine has better error handling. When a temporary error occurs during message sending the message will be send again later (you can define the delay and
number of attempts).
New outgoing queue allows to send some messages in special time intervals (large messages or messages with lower priority).
New there is a possibility to view queued messages including details about selected messages.
New there is a possibility to delete messages from the outgoing queue using WWW Admin interface.
New support for sorting of outgoing messages by size (large messages will be sent after the shorter ones).

HTTP Proxy

New browser to proxy authentication is supported. If enabled the browser asks user for username/password. You can check the credentials against the local user database (Accounts) or you can use an ACL rules.

Access List

New UserLogin object added. It allows to create ACL rules which checks username/password from users HTTP requests (HTTP Proxy and WWW server services supported)
New regular expressions support added
Remarks are allowed in the ACL rules definition. All lines which start with ';' or '#' or '//' are treated as comments.
New Rewrite action defined. It allows to create rules which redirect browser's requests to any other URL.
Service object bug solved. It evaluated service name improperly.
Proxy+ adds protocol definition (https://) in the case the browser send a request to access secured (SSL) site. Because the browser sends the URL without the protocol definition Access List feature (URL objects) didn't work as users expected (filter containing the 'https://' didn't match the 'https://www.server.com' for example). Now all (HTTPS and non-HTTPS URLs passed to the ACL rules use the same syntax).

Sorting rulesets

New It is possible that 'Append To' value is not added to some rule patterns. If the rule pattern contains '~' character at the end, 'Append to' is not used.
New special recipient of a message is supported. You can select -Ignore- as a recipient of the message. In that case the message will not be sent to a real user but it will be signed as delivered and deleted. You can use the feature to filter some unwanted messages (spam).
Solved bug which caused the Proxy+ hang-ups when keywords in the rule were separated by ' ;' (space and semicolon) characters.

DNS Forwarder

bug with logging the name of requested action solved.
TCP stream requests are logged too.

WWW Admin

New Utilities menu added. Some actions from Additional menu were moved there.
New Ping utility. It allows to measure the response time from a remote server.
New Traceroute utility. It allows to test connection to a server.
New RegExp helper utility. It allows to test and debug regular expressions.
There is a possibility to switch State Board's automatic refresh off.

Telnet Gateway

New the Telnet gateway understands native telnet protocol now. It is able to parse and to skip initial telnet protocol options. It stops the garbage you saw when you tried to connect through telnet gateway using Linux telnet.

Error messages

New IE 5.X replaces all error messages with its own problem description if the message is not long enough (512 bytes in most cases). All Proxy+'s error messages were enlarged to be long enough. Custom Error Messages (templates) were changed too - there is a special keyword ('@_ie5padding_@') which adds required padding.
Error messages use server's local time representation now (formerly UTC time was used).

Log files

Sorting rules debugging messages contain an information about the global ruleset settings too.

WWW Server

Solved bug with 404 (not found) code which was written into AccessLog.TXT logfile instead of the 200 code.

Dialing

Maximal number of dialing attempts you can configure was changed to 99 (10 was the previous limit).

Security

the automatic detection of insecure interfaces ignores all interfaces with IP addresses from private ranges (10.x.x.x, 192.168.x.x and 172.16.0.0-172.31.255.255)

Version 2.40 #184 07.07.2000

General

Internal WWW server allows to use custom error messages.
Some internal functions modified to generate more detailed info when the error occurs.

Security

Solved bug which could cause incorrect Insecure Interfaces detection.
Solved bug with evaluating Access List ClientIP and InterfaceIP objects. In some cases parameters of the objects were improperly compared with client/interface IP addresses.

FTP gateway

It is possible to use the '@' characters in the username.

Version 2.40 #182 06.14.2000

Cache

Version 2.40 #176 had a bug which caused no object were stored into the cache (the cache was cleared because Proxy+ improperly
detected the cache free space).

Dialing

Hanging up routines modified.

Logfiles

It is possible to log details about connection establishing/hanging up

Version 2.40 #176 06.08.2000

General

SMTP server uses no RAS API functions if the Proxy+ is configured to work on leased lines (Leased Line (None) in Dial\General).

HTTP Proxy

Solved problem with removing of spaces from the HTTP header fields. Prior versions of P+ replaced multiple spaces with one space. It could cause problems when the WWW server sent the Cookie which contained multiple spaces for example.

Dialing

Some functions which detect or enumerate the dial up networking state and names of defined connections slightly changed.

Cascading

Now the username/password pair is sent to the parent proxy server when the client sends HTTPS, FTP or GOPHER type requests.
ICP requests were improperly composed when the HTTPS URL was asked for
Solved bug in the detection of the best parent/sibling ICP cache

Logging subsystem

Problems with logfile rotation solved (Monthly and Custom modes rotated the files every day).

Version 2.40 #174 06.08.2000

General

A lot of minor bug fixes and improvements.
New External definition of Content-type association table allowed.
New Custom error messages. It is possible to create new texts and looks of HTTP like error messages (messages sent to the browser).
DoWinService.Exe utility removed from installation archive. If you want to configure Proxy+ to run as a service on Windows 95/98 you have to use Proxy+'s WWW Admin interface (Administrator/Additional page).
Critical error messages (exceptions) contains detailed description of Windows version. You can find detailed operating system version on the System Info page too.
The complete Proxy+ version information is displayed on the top of the main window (version and the build number)
The problem with the system tray icon solved. Now the icon is properly displayed even the Proxy+ starts as Windows 95/98 service.
It is possible to enable/disable System Tray Icon if the main windows is not visible.

Security

Important Insecure interfaces - a list of automatically detect insecure interfaces
Most of services disabled by default (Telnet Gateway, SOCKS)
Access List behavior slightly changed. When the Access List Objects are loaded Proxy+ will not stop loading of objects when the first objects fails (due to incorrect definitions of parameters for example)

Mail system

New Improved sorting rulesets. Now it is possible to sort the messages using Received: header fields, to write debugging messages when message goes through sorting rules. Message header fields are preprocessed (converted to the unified format and national encoded strings are decoded).
SMTP authentication problem solved - now the Proxy+ sends one username/password credentials per session.
New 100 recipients per message limit removed. We found out that most (maybe all) mail clients improperly solve this situation so the client can send unlimited (until memory exhausted) number of recipient per message.
problem with accounts which have empty password and Local Email assigned solved.
Proxy+ adds some additional header fields into messages delivered to the local boxes. These fields allows to identify the service which received/downloaded the message and to identify the message (TimeStamp fields).
POP3 server UIDL command can be disabled or configured to run more quickly. If the UIDL command is enabled it takes some time per message when the box is opened (unique MD5 sum is calculate for each file) so if you don't delete the messages from box it can cause problems when the number of messages reaches several hundred.
problem with "Mail relaying" solved. There was a bug - it was not possible to deny relaying of messages in some cases.
Message-ID is logged when the message is sent/received.
POP3 server can redirect requests like the POP3 Mapped Link to the remote POP3 server
list of external email addresses supported

Cascading

New It is possible to define username/password for each parent/sibling proxy server.
NON-ICP cascading statistics included.

HTTP Proxy

A several non-standard time formats produced by WWW servers added.
New It is possible to configure HTTP service to send no user related data to the WWW server.
New It is possible to turn on the debugging messages.

FTP Proxy

When the URL doesn't contain any password the one from HTTP header is used (if the Authenticate: field exists).
Problem with Netscape SmartUpdate solved.

Logging subsystem

New Custom AccessLog.TXT file formats allowed. Three formats predefined (W3C, Squid, MS Proxy 2).
New Customizable logfile names. There is possibility to change the log name suffix
Logfiles are rotated (it Proxy+ is running) at the midnight. Several rotation interval predefined (Daily, Weekly, Monthly,..)
The time when the logs are rotated is server local time representation (older version used GMT time instead).
AccessLog.TXT native format slightly changed.
It is possible to change the logfiles home directory.
Parameters of WWW Admin requests are not logged by default. The AccessLog.TXT file doesn't contain passwords and other information from WWW Admin requests. The feature can be switched on/off.
It is possible to configure Proxy+ to don't store parameters from requested URLs (HTTP Proxy, FTP Proxy, Gopher Proxy) to the AccessLog.TXT logfile

WWW Admin

New Confirmation of dangerous actions required. It can be disabled.

Connection establishing

The "668 error code" bug solved. It appeared on Windows2000 systems when the dial up connection failed due to a busy line.

Cache manager

Problem with erasing unused object solved. Proxy+ deletes all unused objects from disc cache now.

Version 2.20 #88 05.20.1999

Mail server

bug with accepting of some mails was solved. When mail client sent large message with MIME without encapsulation (no base64 nor quoted-printable, etc) then rarely previous version of P+ didn't accept these messages.

Version 2.20 #86 05.14.1999

General

option "Enable auto hang up" is enabled by default.
Hang Up item was added to the P+'s window system menu.

WWW Admin

SOCKS server

BIND requests are processed in new way on Windows 98 and Windows NT with SP4 (or higher). It allows better BIND
functionality with application as ICQ, mIRC (DCC functions).
solved bug with BIND 5 requests.
now you can enable logging of details from SOCKS function processing.
