Therefore, 3/6 is a safer setting.[br] + The maximum protection you can set is 0 messages within any number of seconds; in that case any + CTCP request will be considered a flood and ignored.[br] + [br][br] + You can also decide to ignore specific CTCP requests. For example, if you don't want to reply to PING + requests, just select "PING" under the "Ignored Requests" section.[br] + [br][br] + Some specific protection options can be set also in other CTCP options sections: + see the [widget:ctcpavatarprotooptions]CTCP AVATAR protocol options[/widget] and [widget:ctcpdccprotooptions]CTCP DCC protocol options[/widget].[br] +*/ + + +KviCtcpFloodProtectionOptionsWidget::KviCtcpFloodProtectionOptionsWidget(QWidget * parent) +: KviOptionsWidget(parent,"ctcpfloodprotection_options_widget") +{ + createLayout(4,2); + + KviBoolSelector * b = addBoolSelector(0,0,1,0,__tr2qs_ctx("Use flood protection (recommended)","options"),KviOption_boolUseCtcpFloodProtection); +#ifdef COMPILE_INFO_TIPS + mergeTip(b,__tr2qs_ctx("<center>This option makes KVIrc only respond to a limited number of CTCP requests within a specified time interval, to prevent \"flooding\" CTCP messages.</center>","options")); +#endif + KviUIntSelector * u = addUIntSelector(0,1,0,1,__tr2qs_ctx("Allow up to:","options"),KviOption_uintMaxCtcpRequests,0,10000,3,KVI_OPTION_BOOL(KviOption_boolUseCtcpFloodProtection)); + u->setSuffix(__tr2qs_ctx(" requests","options")); +#ifdef COMPILE_INFO_TIPS + mergeTip(u,__tr2qs_ctx("<center>Minimum value: <b>0 requests</b><br>Maximum value: <b>10000 requests</b></center>","options")); +#endif + connect(b,SIGNAL(toggled(bool)),u,SLOT(setEnabled(bool))); + u = addUIntSelector(1,1,1,1,__tr2qs_ctx("within:","options"),KviOption_uintCtcpFloodCheckInterval,1,3600,6,KVI_OPTION_BOOL(KviOption_boolUseCtcpFloodProtection)); + u->setSuffix(__tr2qs_ctx(" sec","options")); +#ifdef COMPILE_INFO_TIPS + mergeTip(u,__tr2qs_ctx("<center>Minimum value: <b>1 sec</b><br>Maximum value: <b>3600 sec</b></center>","options")); +#endif + connect(b,SIGNAL(toggled(bool)),u,SLOT(setEnabled(bool))); + + KviTalGroupBox * g = addGroupBox(0,2,1,2,2,Qt::Horizontal,__tr2qs_ctx("Ignored Requests","options")); + addBoolSelector(g,__tr2qs_ctx("PING","options"),KviOption_boolIgnoreCtcpPing); + addBoolSelector(g,__tr2qs_ctx("FINGER","options"),KviOption_boolIgnoreCtcpFinger); + addBoolSelector(g,__tr2qs_ctx("CLIENTINFO","options"),KviOption_boolIgnoreCtcpClientinfo); + addBoolSelector(g,__tr2qs_ctx("USERINFO","options"),KviOption_boolIgnoreCtcpUserinfo); + addBoolSelector(g,__tr2qs_ctx("VERSION","options"),KviOption_boolIgnoreCtcpVersion); + addBoolSelector(g,__tr2qs_ctx("SOURCE","options"),KviOption_boolIgnoreCtcpSource); + addBoolSelector(g,__tr2qs_ctx("TIME","options"),KviOption_boolIgnoreCtcpTime); + addBoolSelector(g,__tr2qs_ctx("PAGE","options"),KviOption_boolIgnoreCtcpPage); + addBoolSelector(g,__tr2qs_ctx("AVATAR","options"),KviOption_boolIgnoreCtcpAvatar); + addBoolSelector(g,__tr2qs_ctx("DCC/TDCC","options"),KviOption_boolIgnoreCtcpDcc); + + addRowSpacer(0,3,1,3); +} + +KviCtcpFloodProtectionOptionsWidget::~KviCtcpFloodProtectionOptionsWidget() +{ +} + + +#include "m_optw_ctcpfloodprotection.moc" |
