Re: Can send but can't receive mail
hi, some ISPs block outgoing traffic on port 25 (smtp) for domestic connections, and give you credentials to use THEIR smtp server (to control spam i think). maybe this is your case...

raid recomendation
hi, i have a new dell r720 server with 5 600gb disks. his function will be a postgresql server (the size of the databases is really small with 600gb we should be fine for a long time). which raid configuration would you recommend? i was thinking in raid 5 with all five disks but i am not a expert. i prefer redundandcy against size (i mean, i can sacrifice space). and i dont want performance degradation for doing raid with an incorrect number of disks. thanks in advance! -- Roberto Scattini

debug apache-php dump
hi list, i want to know how can i "bind" php symbols to apache in order to debug an apache2 coredump file. i upgraded my system to debian squeeze, and suddenly my web application started to generate "segmentation faults" randomly. it is a standard package installation, apache2, php5 and libapache2-mod-php5. i also installed apache2-dbg, libapr1-dbg, libaprutil1-dbg and php5-dbg. i generated an apache coredump file, but when i open dump file with gdb the only i get is this: # gdb /usr/sbin/apache2 /var/cache/apache2/core GNU gdb (GDB) 7.0.1-debian Copyright (C) 2009 Free Software Foundation, Inc.
