Salve, come da topic.
Ho più volte messo su un server ftp con cui uppo le mappe di Call Of Duty 2 sulla VPS (Debian) che uso per il server.
Puntualmente ogni volta che il server ftp è attivo viene bucato o comunque aggredito in maniera significativa, tanto da farmelo disabilitare.
Uso proftp come server, vi posto la config sperando vi troviate un po' di caxxate.
Codice:# # /etc/proftpd.conf -- This is a basic ProFTPD configuration file. # To really apply changes reload proftpd after modifications. # ServerName "MyFTPName" ServerType Standalone DeferWelcome off MultilineRFC2228 on DefaultServer on ShowSymlinks on TimeoutNoTransfer 600 TimeoutStalled 600 TimeoutIdle 1200 DisplayLogin welcome.msg DisplayFirstChdir .message #ListOptions "-l" #DenyFilter \*.*/ # Uncomment this if you are using NIS or LDAP to retrieve passwords: #PersistentPasswd off # Uncomment this if you would use TLS module: #TLSEngine on # Uncomment this if you would use quota module: #Quotas on # Uncomment this if you would use ratio module: #Ratios on # Port 21 is the standard FTP port. Port xx21 <----------l'ho cambiata # To prevent DoS attacks, set the maximum number of child processes # to 30. If you need to allow more than 30 concurrent connections # at once, simply increase this value. Note that this ONLY works # in standalone mode, in inetd mode you should use an inetd server # that allows you to limit maximum number of processes per service # (such as xinetd) MaxInstances 3 # Set the user and group that the server normally runs at. User nobody Group nogroup # Umask 022 is a good standard umask to prevent new files and dirs # (second parm) from being group and world writable.

AllowOverwrite on # Delay engine reduces impact of the so-called Timing Attack described in # http://security.lss.hr/index.php?page=details&ID=LSS-2004-10-02 # It is on by default. DelayEngine on # A basic anonymous configuration, no upload directories. DefaultRoot ~ <Anonymous ~ftp> User ftp Group nogroup # We want clients to be able to login with "anonymous" as well as "ftp" UserAlias anonymous ftp # Cosmetic changes, all files belongs to ftp user DirFakeUser on ftp DirFakeGroup on ftp RequireValidShell on # # # Limit the maximum number of anonymous logins MaxClients 1 # We want 'welcome.msg' displayed at login, and '.message' displayed # in each newly chdired directory. DisplayLogin welcome.msg DisplayFirstChdir .message # # Limit WRITE everywhere in the anonymous chroot <Directory *> <Limit READ WRITE STOR> DenyAll </Limit> </Directory> </Anonymous> Include /etc/proftpd.include
e ovviamente il file di inclusione
onestamente di configurazioni dichiarate buone ne ho trovate parecchie ma preferirei che mi si spiegasse anche il perchè di certe impostazioni piuttosto che il dire : "questa è roba buona ... "Codice:<VirtualHost 194.xxx.xxx.xxx> ServerName "DarkZone" Port xx21 #User xxxxxxx #Group xxxxxxxx AllowOverwrite on AllowRetrieveRestart on AllowStoreRestart on DeleteAbortedStores off DefaultTransferMode binary Umask 022 TimeoutLogin 60 TimeoutIdle 600 TimeoutNoTransfer 600 TimeoutStalled 1200 RequireValidShell on DefaultRoot ~ MaxClients 4 AuthPAM on <Limit LOGIN> DenyAll Allow my_user1 Allow my_user2 </Limit> <Directory /*> AllowOverwrite On # <Limit LOGIN> # AllowAll # </Limit> # <Limit READ> # AllowAll # </Limit> # <Limit WRITE> # AllowAll # </Limit> # <Limit STOR> # AllowAll # </Limit> </Directory> </VirtualHost>
per sicurezza ho pure spostato la porta di ssh e inibito il login diretto dell'utente root .
Allo stato attuale, senza ftp, non sto avendo problemi ma la cosa è piuttosto seccante visto che vorrei mettere un pannello per consentire il controllo del server agli altri membri del "club" senza che pasticcino con la console del VPS.
