Package: apache2.2-common
Severity: normal

Hello,

here's a snippet of ports.conf shipped with the package:
---
Listen 80

<IfModule mod_ssl.c>
## Listen 443
</IfModule>
--

if the second 'Listen' directive is uncommented, starting apache2
(/etc/init.d/apache2 [start|reload]) fails with:
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:443
no listening sockets available, shutting down
Unable to open logs

otherwise, everything run fine. A 'netstat -apn' doesn't show any
process bind to port 443.

A strace of 'apache2ctl start' reveals, for one of the child process,
the following problem:

open("/var/run/apache2.pid", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or 
directory)
setsockopt(4, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
setsockopt(4, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0
setsockopt(4, SOL_TCP, TCP_NODELAY, [1], 4) = 0
bind(4, {sa_family=AF_INET, sin_port=htons(80), sin_addr=inet_addr("0.0.0.0")}, 
16) = 0
listen(4, 511)                          = 0
setsockopt(6, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
setsockopt(6, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0
setsockopt(6, SOL_TCP, TCP_NODELAY, [1], 4) = 0
bind(6, {sa_family=AF_INET, sin_port=htons(443), sin_addr=inet_addr("0.0.0.0")},
 16) = 0
listen(6, 511)                          = 0
setsockopt(9, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
setsockopt(9, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0
setsockopt(9, SOL_TCP, TCP_NODELAY, [1], 4) = 0
bind(9, {sa_family=AF_INET, sin_port=htons(443), sin_addr=inet_addr("0.0.0.0")},
 16) = -1 EADDRINUSE (Address already in use)
write(2, "(98)Address already in use: make"..., 77) = 77
close(9)                                = 0
write(2, "no listening sockets available, "..., 46) = 46
write(2, "Unable to open logs\n", 20)   = 20

Now, the funny part:
1) remove 'Listen 443'
2) restart apache2
3) netstat -ap | grep apache
tcp        0      0 *:www                   *:*                     LISTEN     22079/apache2       
tcp        0      0 *:https                 *:*                     LISTEN     22079/apache2       

So ... it seems the 'Listen 443' is automatic with a2enmod ssl ? I
guess the problem is a bad interaction between the
/etc/apache2/ports.conf and some of the installation scripts.

Best regards
