ubunt撥號(hào)上網(wǎng)失???

如果第一次撥號(hào)失敗,正常,再撥兩次,還是不行。;t工作,因此將報(bào)告它以進(jìn)行故障排除。

ubuntu打開telnet服務(wù)具體步驟?

2.安裝成功后,系統(tǒng)也會(huì)進(jìn)行相應(yīng)的提示,并添加如下一行。

并添加以下內(nèi)容:# simpleconfigurationfileforxinetd # # some defaults,and include/etc/xinetd . d/defaults { # pleasenotethatyyouneedalog _ typelinetoableto use log _ on _ success # and log _ on _ # log _ typeSYSLOGdaemoninfo instances 60 log _ typeSYSLOGauthpriv log _ on _ successHOSTPID log _ on _ failure host CPS 2530 } include dir/etc/xin: on # description :thetelnetserver server服務(wù)器會(huì)話;ituses # uncrypted username/passwordpairsforauthentication。service telnet { disableno flags reuse socket _ typestream wait no useroot server log _ on _ failure USERID }

5.重新啟動(dòng)機(jī)器或重新啟動(dòng)網(wǎng)絡(luò)服務(wù)sudo/etc/init.d/xin:以這種修改文件/etc/pam.d/login。只需注釋掉下面一行。#authrequiredlib/security/pam_

8.詳細(xì)配置/etc/xinetd . d/telnet service telnet { disable no bind 192 . 168 . 1 . 2 Only _ from 192 . 168 . 1 . 0/24 #以上兩行表示只提供內(nèi)部網(wǎng)段!instance unlimited nice 0 flags reuse socket _ typestream wait no useroot # server/usr/sbin/telnetd server server _ args-anone log _ on _ failure USERID } service telnet { disableno bind 140 . 116 . 142 . 196 only _ from 140 . 116 . 0 . 0/16 no _ access 140 . 116 . 32 . { 10,26} #上面三行設(shè)置了嚴(yán)格的外部限制。實(shí)例10 umask 022 nice 10標(biāo)志重用socket _ type流等待無(wú)用戶root # server/usr/sbin/Telnetd server log _ on _ failure userid } 9。添加防火墻iptables:如果要telnet到192.168.0.0/24的網(wǎng)段和這個(gè)IP,可以添加以下幾行規(guī)則:/sbin/Iptables-a input-ptcp-ieth 0-s 192 . 168 . 0 . 0/24-d port 23-j accept/sbin/Iptables-a input-ptcp-i:allow *原地址* _ *UBUNTU開通TELNET服務(wù)* 2。安裝成功后,系統(tǒng)也會(huì)有相應(yīng)的提示(好像是710可用,610不可用)。并添加以下行并添加以下內(nèi)容:# simpleconfigurationfile for xinetd # # some defaults,并包含/etc/xinetd . d/defaults { # pleasenonotetheyouneedalog _ typeline to。beable使用log _ on _ success # and log _ on _ # log _ typeSYSLOGdaemoninfo instances 60 log _ typeSYSLOGauthpriv log _ on _ successHOSTPID log _ on _ failure host CPS 2530 } include dir/etc/xin: on # description :thetelenetserver服務(wù)器會(huì)話;伊圖塞
