SBHTTPD

[btechint]

When I:

SBHTTPD -start

After a short while this error:

d:\sb\source\examples\sibawa\sibawastart.bas(0): error &H44:The file can not be read.

------------

This is on a clean-new install, winxp. I installed at: d:\sb

There are no directories in the source dir.

\examples is:
 sb\examples

there is no \sibawa
there is no
sibawastart.bas

----------

My guess is that the config file in the bin dir has info error?

My main area of learning is in trying to get the http engine working, and then getting a server working with the http engine. I need to run cgi perl scripts locally to build database files.

thanks, John

note; this is on an windows xp system

Hi John,

The sibawastart.bas program I believe is part of the authorization extension to Apache and isn't needed to get the application server (sbhttpd) running. Just remove those startup lines in the basic.conf file.

I have three separate sbhttpd servers running on the scriptbasic.net server that work great.

Feel free to send me your basic.conf to have a peek at if you like.

The ScriptBasic interpreter and application server both use the same compiled configuration file. Maintain your basic.conf.txt file in a text editor. Next convert it to the binary format ScriptBasic uses by typing the following command at a console prompt in the /etc/scriba directory.

scriba -k basic.conf.txt


At a minimal, make sure these proxy modules are enabled.

Code: [Select]


LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so


Here is what I added to the end of Apache's httpd.conf file.

Code: [Select]


# ScriptBasic Application Server
ProxyPass /app-bin/ http://127.0.0.1:8080/
ProxyPassreverse /app-bin/ http://127.0.0.1:8080/


You can optionally set the SCRIBACONF environment variable to the full path and filename of where your basic.conf file is located and named. (/etc/scriba/basic.conf is the default location and name if the ScriptBasic environment variable isn't set)

After restarting Apache for the proxy addition, enter the following at a console prompt.

sbhttpd -start

All requests to the /app-bin directory are sent to the ScriptBasic application server to be process.

To stop the server, kill -9 the process ID # in the pid.txt file.

You can expand your application directory structure and hide it's files behind the web root directory. The "/var/www/html/app-bin" directory is the interface between Apache and sbhttpd. It doesn't have to contain any files if you use the ScriptBasic "vdirs" feature.

Code: [Select]


  vdirs (
    dir "/client/:/var/www/private/"
   )


http://sb.dev/app-bin/echo.bas   <-- this will run echo.bas in the webroot /app-bin (if you prefer, the 'home' directory can be defined below webroot , another drive, ... which allows for virtual mapping of your script resources.)

http://sb.dev/app-bin/client/echo.bas  <-- this runs the client version of the program located below the webroot in the private directory

Code: [Select]

If you prefer not to expose your database host, login, password and db_name with the mysql::RealConnect() function, you can define this in the basic.conf file and use the mysql::Connect("accounting") function instead.

Code: [Select]


;
; MySQL configuration
;
mysql (
  connections (
    accounting (  ; the name of the connection
    host "127.0.0.1"  ; the host for the connection
    db "acct"  ; database for the connection
    user "db_user_id"  ; user for the connection
    password "db_password"  ; password for the connection
    port 3306  ; the port to use
    socket ""  ; the name of the socket or ""
    flag 0  ; the client flag
    clients 10  ; how many clients to serve before really closing the connections
    )
  )
 )

Code: [Select]


client (
    allowed "127.0.0.1/255.255.255.255"
    allowed "16.94.58.4/0.0.0.0"

    denied "127.0.0.1/0.0.0.0"
    denied "16.192.68.5/255.255.0.0"
    )


You can define the client IPs that are allowed and denied to connect to the engine. This is the real client that is connecting to the listener on the socket and trying to get access via HTTP and not the client reported by any proxy header field. You can use this configuration option to allow only the web server machine to connect to the engine via the proxy module and disallow all external connections that may try to connect from external machines. You can also use this option to configure a client application not to be accessed by external computer.

A connection is accepted by the engine if there is at least one allowed configuration line that allows the connection and there is no any denied configuration line that denies the connections.

The string following the keywords allowed or denied should contains the IP number and the MASK separated by a slash. When the client IP is calculated first it is bitwise AND-ed by the MASK and compared to the IP number. Thus

allowed "127.0.0.1/255.255.255.255"

allows only connections from the localhost and

denied "127.0.0.1/0.0.0.0"

denies access for no-one (in other word this line is waste of CPU and text file, but is good as an example). The line

denied "16.192.68.5/255.255.0.0"

disallows all requests that come from an IP number 16.192.*.* that is some internal sub-network of the once existed firm: Digital Equipment Corporation.

The ScriptBasic application server gives you the flexibility to extend your reach to other system facilities but gives you the means to protect your site from unwanted external activity. (web and intranet environments)

And finally to answer your original question.

' sibawastart.bas
'
' This program is started by the SIBAWA system when the application starts.
'
' This program loads the cache authentication and access control into memory
' and also maintains the session data handling session time outs.


This feature manages the directory .htaccess authentication and caches it. Peter has included session handling support and a browser based management interface to setup users and access levels.

Apache Authentication, Authorization, and Access Control

(One of the ScriptBasic gifts I haven't opened yet.  :wink: )

I was able to get sbhttd working. I had questions about the ip allow-disallow, but your help notes answered them. I was also wondering about the pid.txt. A problem I have now is that the sbhttd will not stop. I have tried
sbhttd stop
sbhttd -stop
I see that I can use kill [-pid (number)]. Not sure yet what that is or how to use it.

Here is what I did. Edited the scriba.conf.lsp file so everything pointed to my dir's. Deleted the sibawa references. Changed the ip list to;
allowed "127.0.0.1/255.255.255.255"
port 80

Made a new scriba.conf using:

scriba -k scriba.conf.lsp

When I enter:

sbhttd -start

The example files load and seem to work.

sbhttp -install

seems to work

Being a complete newb, have some concern about leaving my system open the scrupulous from the net, will have to figure out the IP thing.

Thanks

The pid.txt file contains the main active process ID for sbhttpd. Just cat the file, get the number and kill -9 ####.

You can delete the pid.txt file and sbhttpd will die on it's own. (it may take a minute due to running threads need to finish)

Good to hear you got it going !
