Both these attacks and SYN flooding target the victim's TCP application and can interrupt the victim's service at much less cost than brute force flooding packet methods. However, SYN flooding is very different from other TCP spoofing attacks. SYN flooding attacks the services of the new connection without affecting the established connection, while other spoofing attacks break the established connection and cannot block the new connection from the beginning. SYN attacks can be stopped only by modifying the initial handshake program, while other spoofing attacks require checking every piece of data throughout the connection life cycle. What SYN flooding and other TCP spoofing attacks have in common is that they all depend on the attacker's ability to send IP packets that disguise the source address, while the same way to defend them is to deploy more address filtering or use IP Security Protocol (IPsec).　　在险象环生的斗智斗勇中，原本一心为财的马天明被革命者蔡里昆的高风亮节所打动，真正成长为一个深晓民族大义的共产党人，最终战胜了恶徒，完成了组织交予的任务，同时也为自己洗清了冤屈。　　贪婪阴险的孙大妈伙同崔胡子和胭脂虎夫妻两，设计将大香卖到了两人经营的妓院中，大香就此沦为妓女。眼看女儿遭受着非人的待遇，绝望的佟李氏选择了跳河自尽。然而尚幼林却没有放弃希望，想方设法替大香赎身，却最终以失败告终。1949年北平解放，解放军的到来让大香终于重新获得了自由。不对。再看了她一眼，才转身走了。If the picture is loaded, the load event will be triggered.该剧以宏大的历史视野，正面地完整地真实地形象地再现一九四九年到一九五四年期间中国革命进程和在中国发生的翻天覆地的变化。全方位展现了北平和平解放、西柏坡党的七届二中全会、国共和谈、渡江战役、上海金融大战、签署《中苏友好同盟互助条约》、和平解放新疆、解放大西南、中国人民志愿军赴朝鲜战场、和平解放西藏等一系列波澜壮阔的革命历史画面。演绎了国共两党在军事、政治、经济、统战以及秘密战线等各个领域的全面较量；歌颂了人民群众衷心拥护革命、推动历史前进的伟大力量；颂扬了爱国民主人士为中国革命作出的特殊贡献。展示了以毛泽东为首的革命领袖的丰功伟业，特别是毛泽东放眼世界、实现民族大团结的雄才大略以及求贤若渴的平民意识和领袖胸襟。
