Re: [alpine-devel] Minimal ram requirements?

Hello,


I guess it depends of the usage, but it can be useful even with only 64 MB.

Here are some current stats from my master "AlpineDirectory" system (master
DNS+DHCP+master LDAP+master Kerberos+NTP) running on a Soekris net4501 :

cerbere:~# uname -a
Linux cerbere 2.6.32.15-grsec #8-Alpine SMP Wed Jun 16 11:26:43 UTC 2010
i486 GNU/Linux

cerbere:~# free
              total used free shared buffers
  Mem: 51876 48744 3132 0 700
 Swap: 0 0 0
Total: 51876 48744 3132

cerbere:~# uptime
 12:50:57 up 429 days, 2:23, load average: 0.00, 0.02, 0.00


The same for its slave (slave DNS+slave LDAP+slave Kerberos+NTP+Squid) :

charon:~# uname -a
Linux charon 2.6.32.15-grsec #8-Alpine SMP Wed Jun 16 11:26:43 UTC 2010
i486 GNU/Linux

charon:~# free
              total used free shared buffers
  Mem: 51876 49068 2808 0 36
 Swap: 0 0 0
Total: 51876 49068 2808

charon:~# uptime
 12:57:09 up 429 days, 2:30, load average: 0.06, 0.01, 0.00
