电信tp路由器 默认密码规则

电信tp路由器默认密码规则摘要:1.电信TP路由器简介2.电信TP路由器默认密码规则3.修改电信TP路由器密码的方法4.增强电信TP路由器安全性的建议正文:【电信TP路由器简介】电信TP路由器,即中国电信提供的宽带路由器,是用户在办理宽带业务时常见的设备。
它可以让多个设备通过一个网络接口连接到互联网,方便用户在家庭或企业环境中使用。
这类路由器通常具有有线和无线网络功能,支持WAN(广域网)和LAN(局域网)连接。
【电信TP路由器默认密码规则】电信TP路由器的默认密码规则通常如下:- 用户名:admin- 密码:admin请注意,这个密码是出厂时的默认设置,为了保障网络安全,建议用户在首次使用时立即进行修改。
【修改电信TP路由器密码的方法】1.打开浏览器,输入路由器的IP地址,一般为192.168.1.1或192.168.0.1,进入路由器管理界面。
2.输入用户名和密码,默认用户名为admin,密码为admin。
3.在路由器管理界面,找到“用户管理”或“账户管理”选项,修改用户名和密码。
4.为了安全起见,建议使用复杂密码,包括字母、数字和特殊字符,避免使用过于简单的密码。
【增强电信TP路由器安全性的建议】1.修改默认管理员密码:如上所述,修改路由器管理员密码为复杂且不易被猜测的密码,以防止被恶意攻击。
2.启用WPA2加密:在路由器设置中,启用WPA2或更高级别的无线加密协议,以保护无线网络不被破解。
3.限制设备访问:在路由器管理界面,限制允许访问路由器的设备列表,避免陌生人接入网络。
4.关闭DHCP功能:如果不需要自动分配IP地址,可以关闭DHCP功能,以减少攻击面。
5.定期更新路由器固件:定期查看路由器厂商官网,更新路由器固件,修复已知的安全漏洞。
总之,电信TP路由器的默认密码为admin/admin,为了网络安全,建议用户在首次使用时立即修改。

端口号对应的协议

端口号对应的协议篇一:常用协议对应的端口号标题:常用协议对应的端口号由Anonymous 于星期日, 04/01/2007 - 01:28 发表DHCP:服务器端的端口号是67DHCP:客户机端的端口号是68POP3:POP3仅仅是接收协议,POP3客户端使用SMTP向服务器发送邮件。
POP3所用的端口号是110。
SMTP:端口号是25。
SMTP真正关心的不是邮件如何被传送,而只关心邮件是否能顺利到达目的地。
SMTP具有健壮的邮件处理特性,这种特性允许邮件依据一定标准自动路由,SMTP具有当邮件地址不存在时立即通知用户的能力,并且具有在一定时间内将不可传输的邮件返回发送方的特点。
Telnet:端口号是23。
Telnet是一种最老的Internet应用,起源于ARPNET。
它的名字是“电信网络协议(Telecommunication Network Protocol)”的缩写。
FTP:FTP使用的端口有20和21。
20端口用于数据传输,21端口用于控制信令的传输,控制信息和数据能够同时传输,这是FTP的特殊这处。
FTP采用的是TCP连接。
TFTP:端口号69,使用的是UDP 的连接。
端口号的作用及常见端口号用途说明IP协议是由TCP、UDP、ARP、ICMP 等一系列子协议组成的。
其中,主要用来做传输数据使用的是TCP和UDP协议。
在TCP和UDP协议中,都有端口号的概念存在。
端口号的作用,主要是区分服务类别和在同一时间进行多个会话。
举例来说,有主机A需要对外提供FTP和WWW两种服务,如果没有端口号存在的话,这两种服务是无法区分的。
实际上,当网络上某主机B需要访问A的FTP服务时,就要指定目的端口号为21;当需要访问A的WWW服务时,则需要将目的端口号设为80,这时A 根据B访问的端口号,就可以区分B的两种不同请求。
这就是端口号区分服务类别的作用。
再举个例子:主机A需要同时下载网络上某FTP服务器B上的两个文件,那么A需要与B同时建立两个会话,而这两个传输会话就是靠源端口号来区分的。

摘要 设 计者对零件表面粗糙度的要求是否合理, 不仅影响零 件的使用性能和寿命, 对零件
的制造成本也有很大 的影响。1993 年国家正 式实施新的表面粗糙 度标准, 取 代了 1983 年的 旧标准。由于新、旧标准的符号、代号及标注法相近, 但 含义有所区别, 在实际应用中出现了混 淆现象。本文对新旧标准中表面粗糙度的标注进行了 对比分析。

十、使用注意事项
外围电路对TP83系列升压转换芯片性能影响很大,需合理选择外部器件:
1) 外接电容值不宜小于47μF(电容值过小将导致输出纹波过大),同时要有良好的频率特性(最好使用钽电容或高频电容)。
此外,由于LX开关驱动晶体管关断时会产生一尖峰电压,电容的容压值至少为设计输出电压的3倍;(普通的铝电解电容ESR值过高,所以可选购专门应用于开关式DC/DC转换器的铝电解电容)。
2) 外接电感值要足够小以便即使在最低输入电压和最短的LX开关时间内能够存储足够的能量,同时,电感值又要足够大从而防止在最高输入电压和最长的LX开关时间时ILXMAX超出最大额定值。
此外,外接电感的直流阻抗要小、容流值要高且工作时不至于达到磁饱和。
3) 外接二极管宜选择具有较高切换速度的肖特基二极管。
4) 客户若驱动大电流负载(大于150mA),而纹波要求不高,则可以减小电感(22uH左右);
注意事项:
1)该芯片为驱动大负载而设计,所以外围元器件与芯片距离越小越好,连线越短越好。
特别是接到OUT 端的元器件应尽量减短与电容的连线长度;
2)特别建议使用钽电容;如果在芯片OUT和Vss两端并接电解电容时需要并接0.1-1µ的陶瓷电容。
3)Vss端应充分接地,否则芯片内部的零电位会随开关电流而变化,造成工作状态不稳定。
