Ciao ragazzi ho ricevuto questa mail dopo aver eseguito lo scan con il modulo Watchdog.
Scusate al domanda ignorante ma cossa significa ?
Ho capito che esiste una falla poichè è possibile effettuare il login come root !!
ma come porre rimedio ?
Scusate, mi rendo conto della stupidità della domanda e che la risposta + ovvia è: "se gestis una VPS dovresti essere in grado di tenerla in sicurezza !!!""Codice:This letter was generated by security scanner started on host miosito.it at Apr 20, 2009 09:13 PM. Note: It is recommended that you re-run security scanning on the machine via Plesk control panel before you make any changes to the machine configuration. Security scanning generated the following warnings (the full scanning log is available at /var/log/rkhunter.log): [21:13:11] ------------------------- Security advisories ------------------------- [21:13:11] Warning: root login possible. Change for your safety the 'PermitRootLogin'
ma credetemi è c'è la metto tutta ...
è solo colpa di quella maledetta laurea in economia ...
Grazie per l'eventuale aiuto
Di seguito allego il log dello scan :
