Actually issue was graphing in the IP Distribution section. IP Distribution is graphing based on Protocol Definition and if you're using more then 20 characters to define name in protocol definition NTOP will crash.
Example of this would be THIS_IS_VERY_LONG_DEFINITION=1-1000 Maybe NTOP should trim anything over 20 characters when loading protocol defs. Also where can I disable graphs in the IP Distribution? When a host has lot of defined protocols graphs become hard to read and interpret. A table above IP Distribution graph (such as above Protocol Distribution) would also be nice.

Unfortunately, there isn't a lot of error testing or return codes in those libraries. I'm guessing that ntop is passing it bad data and it's reacting. (Reminds me of my favorite compiler - no, MUSIC's Pascal - it would accept illegal syntax and generate unexecutable code) You are talking about the "info about host xxxx" page, right (url would be 192.168.1.1.html)??? The graphics there are in the "Protocol Distribution" section. What do you get if you comment out those lines in reportUtils.c around 1753... #ifdef HAVE_GDCHART { totalSent = el->tcpSentLoc+el->tcpSentRem+ el->udpSentLoc+el->udpSentRem+ el->icmpSent+el->ospfSent+el->igmpSent+el->stpSent+ el->ipxSent+el->osiSent+el->dlcSent+ el->arp_rarpSent+el->decnetSent+el->appletalkSent+ el->netbiosSent+el->qnxSent+el->otherSent; totalRcvd = el->tcpRcvdLoc+el->tcpRcvdFromRem+ el->udpRcvdLoc+el->udpRcvdFromRem+ el->icmpRcvd+el->ospfRcvd+el->igmpRcvd+el->stpRcvd+ el->ipxRcvd+el->osiRcvd+el->dlcRcvd+ el->arp_rarpRcvd+el->decnetRcvd+el->appletalkRcvd+ el->netbiosRcvd+el->qnxRcvd+el->otherRcvd; if((totalSent > 0) || (totalRcvd > 0)) { if(snprintf(buf, sizeof(buf), "<TR %s><TH "TH_BG" ALIGN=LEFT>Protocol Distribution</TH>", getRowColor()) < 0) BufferOverflow(); sendString(buf); if(totalSent > 0) { if(snprintf(buf, sizeof(buf), "<TD "TH_BG" ALIGN=RIGHT COLSPAN=2><IMG SRC=hostTrafficDistrib-%s"CHART_FORMAT"?1></TD>", el->hostNumIpAddress[0] == '\0' ? el->ethAddressString : el->hostNumIpAddress) < 0) BufferOverflow(); sendString(buf); } else { sendString("<TD "TH_BG" ALIGN=RIGHT COLSPAN=2> </TD>"); } if(totalRcvd > 0) { if(snprintf(buf, sizeof(buf), "<TD "TH_BG" ALIGN=RIGHT COLSPAN=2><IMG SRC=hostTrafficDistrib-%s"CHART_FORMAT"></TD>", el->hostNumIpAddress[0] == '\0' ? el->ethAddressString : el->hostNumIpAddress) < 0) BufferOverflow(); sendString(buf); } else { sendString("<TD "TH_BG" ALIGN=RIGHT COLSPAN=2> </TD>"); } sendString("</TD></TR>"); } } #endif ? At least you will be able to see the table entries above which give the values being graphed... What's interesting is that the generation routine is at line 42 (significant??) in graph.c Also, you could add traceEvent(TRACE_INFO, "") in graph.c just before the call: GDC_out_pie(250, /* width */ 250, /* height */ fd, /* open file pointer */ GDC_3DPIE, /* or GDC_2DPIE */ num, /* number of slices */ lbl, /* slice labels (unlike out_png(), can be NULL */ p); /* data array */ to print the values of lbl and p for num slices... something like this: { int pIndex; for (pIndex=0; pIndex<num; pIndex++){ traceEvent(TRACE_INFO, "slice %3d, label is '%s', value is '%f'\n", pIndex, lbl[pIndex], p[pIndex]); } } (of course, the NULL mutex problem also worries me - I thought that had stopped occuring...) -----Burton -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Domski, Samuel Sent: Tuesday, February 19, 2002 10:01 PM To: [EMAIL PROTECTED] Subject: [Ntop] NTOP Web Interface Crashing Hi All, I have interesting problem running NTOP.
