這篇比較新，安裝在/var/www/mrtg 用Alias /mrtg "/var/www/mrtg/" 的方式改成/mrtg

執行env LANG=C /usr/bin/mrtg /etc/mrtg.cfg 出現錯誤
Received SNMP response with error code error status: noSuchName index 2 (OID: 1.3.6.1.2.1.2.2.1.16.1) SNMPv1_Session

The default settings of the SNMP were too restrictive for MTRG to access what it needed. Here is the revised section of the snmpd.conf file:
Code:
#### # First, map the community name "public" into a "security name" # sec.name source community com2sec linuxbox default public #### # Second, map the security name into a group name: # groupName securityModel securityName group mrtggrp v1 linuxbox group mrtggrp v2c linuxbox #### # Third, create a view for us to let the group have rights to: # name incl/excl subtree mask(optional) view mrtgview included .1 80 #### # Finally, grant the group read-only access to the systemview view. # group context sec.model sec.level prefix read write notif access mrtggrp "" any noauth exact mrtgview none none # -----------------------------------------------------------------------------
lubuntu 22.04 安裝過程記錄
apt-get install snmpd snmp vi /etc/snmp/snmpd.conf 新增一行 rocommunity public localhost 重啟 snmpd systemctl restart snmpd 測試snmpd snmpwalk -v 2c -c public localhost 安裝 MRTG apt-get install mrtg 重建 /etc/mrtg.cfg 檔案 cfgmaker public@localhost > /etc/mrtg.cfg 建立給 MRTG 的首頁 indexmaker /etc/mrtg.cfg > /var/www/html/mrtg/index.html 如果有出現ERROR: did not find any matching data in cfg file 才需要做 再做一次indexmaker /etc/mrtg.cfg > /var/www/html/mrtg/index.html env LANG=C /usr/bin/mrtg /etc/mrtg.cfg 有錯誤找上面的文章解決 service snmpd restart 五分鐘執行一次 crontab -e */5 * * * * env LANG=C /usr/bin/mrtg /etc/mrtg.cfg
