Nicht benötigte Pakete deinstallieren...

[NemesisFS]

Hi,
ich habe heute meinen vServer mit Debian erhalten. Ist alles soweit auch in Ordnung, nur habe ich einige Pakete bemerkt, die ich nicht benötige, bzw. die unerwünscht sind, konkret wäre das apache2. Nun wollte ich spontan via

apt-get remove --purge apache*

das alles runterwerfen, habe jedoch danach folgende liste erhalten, die mich ein wenig erschlagen hat:

Do you want to continue [Y/n]?

Nun weiß ich nicht, ob ich continuen will, da das doch einige Pakete sind, gehören die wirklich alle auschließlich(!) zu apache?
abgesehen davon hänge ich mal eine textfile mit dpkg -l an, evtl kann mir ja jemand sagen, welche Pakete darin nicht benötigt werden, habe eigentlich nur denyhosts und openvpn von hand installiert.

EDIT: was mir grad noch eingefallen ist, eher so nebenbei: kann mir jmd ein tool empfehlen, mit dem ich das system überwachen kann, dh netzwerktraffic sehe, logins, vorallem auch die erfolgreichen, wenn configdateien verändert werden oder so ein kram halt... der server läuft 3 tage und die auth.log enthält schon 8585 zeilen

Ja die 8 unten aufgeführten Pakete, ist schon richtig. Die in der Liste geführten Pakete hast du gar nicht installiert.

okay, vielen dank =)

 

[tuxberlin23]

und zu deinem "überwachen"... zBhttp://www.icinga.org/ benötigt aber apache2 =)

das apache zeug kannst du bedenkenlos deinstallieren.

logins etc. überwachen kannst du einfach mit last. dazu sind keine speziellen weiteren tools nötig.
und dass deine auth.log groß wird ist normal. im netz sind viele bots unterwegs die nach ssh servern suchen und passwortlisten ausprobieren. du solltest drauf achten alle accounts auf dem server entsprechend zu sichern (also keine accounts "admin" mit passwort "test" etc.).
