I've seen the "From IE 5.x and 6.0 i got a blank page with this html" problem. Pressing STOP and then re-retrieving is a work-around. I think it's a timing problem with the multiple connections.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=windows-1252"></HEAD> <BODY></BODY></HTML> Is the internally generated "Gee, I can't make a connection to that site" page from Windows. "From opera 5.05 i got a pop up error saying "connection closed by remote server" sounds like a similar type of error. I honestly think this is all related. And unless somebody is willing to re-write the internal ntop web server to make it "faster" in the single threaded part, it's not going to get better. Moving to another server isn't an answer - it's STILL got to make the call into ntop to retrieve the data. Apache et al is an awfully heavy weight answer for a dozen html files (About.html, help.html, IPTraffic.html, Admin.html, index.html etc.) The only way I could think to solve it is for ntop to create another worker thread to respond to server requests, and have the current handler thread just queue requests to the worker. That way the "blocked" time would be shortened - but not eliminated. The worker would still be single threaded until the read-only determination was made, so that ntop doesn't have to be rewritten to be totally thread safe. -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Pietro Bandera Sent: Thursday, July 18, 2002 10:07 AM To: [EMAIL PROTECTED] Cc: Pietro Bandera Subject: R: [Ntop] NTOP 2.1 problem So here they are, and also i attached the debug i hope it's useful: Host frame: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=windows-1252"></HEAD> <BODY></BODY></HTML> Left frame: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <!-- Converted to html 4.01 Transitional by Burton Strauss, Feb2002 --> <!-- Validated as HTML 4.01 Transitional by Burton Strauss, 26Feb2002 --> <!--meta http-equiv="Content-Type" content="text/html; charset=utf-8" --> <meta http-equiv="Expires" content="0"> <meta http-equiv="Pragma" content="no-cache"> <meta http-equiv="Content-Style-Type" content="text/css"> <meta http-equiv="Window-target" content="_top"> <meta name="ROBOTS" content="NOINDEX,NOFOLLOW"> <meta name="description" content="ntop (http://www.ntop.org) status for a network."> <meta name="author" content="ntop"> <meta name="generator" content="ntop v2.0"> <link rel="stylesheet" type="text/css" href="style.css"> <title>ntop statistics menu (normally a frame)</title> </head> <body background=white_bg.gif> <p><a href="http://www.ntop.org/"; target="_top"><img border="0" src="ntop.gif" width="59" height="49" alt="ntop logo"></a></p> <span class="leftmenuitem"><img src="collapsed.gif" alt="Menu name is Statistics"> Statistics</span> <hr /> <span class="leftmenuitem"> <a href="multicastStats.html" target="area">Multicast</a></span> <hr /> <span class="leftmenuitem"> <a href="trafficStats.html" target="area">Traffic</a></span> <hr /> <span class="leftmenuitem"> <a href="hostsInfo.html" target="area">Hosts</a></span> <hr /> <span class="leftmenuitem"> <a href="thptStats.html" target="area">Network Load</a></span> <hr /> <span class="leftmenuitem"> <a href="domainTrafficStats.html" target="area">Domain</a></span> <hr /> <span class="leftmenuitem"> <a href="showPlugins.html" target="area">Plugins</a></span> <hr /> </body> </html> -----Messaggio originale----- Da: Burton M.

Please do what I asked - right click IN THE MAIN FRAME and do that view source. You did the one off the menu tree, which retrieves the main frameset. I'm interested in what's IN that part of the frame. Also, try pressing STOP and then enter to re-retrieve... -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Pietro Bandera Sent: Thursday, July 18, 2002 8:13 AM To: 'Burton M.

I use gcc-2.95.4-4j on yellow dog 2.3 and gcc-2.95.3-1tr on trustix 1.5 On red hat7.3 i use gcc-2.96-110 Maybe there is a problem compiling ntop2.1 with gcc 2.95?
