LinuxQuestions.org - sysctl 'Permission Denied' issues

Hi, I am using a CentOS 6 VPS and trying to install Domino 8.5. Following various instructions I am trying to fix the following errors by manually editing the sysctl.conf file:

Code:

Error - can't open /proc/sys/fs/file-max.

        errno: 13

        Permission denied

/proc/sys/kernel/shmmax has been set to "268435456".

/proc/sys/kernel/sem has been set to "250      256000  32      1024".

Error - can't open /proc/sys/net/ipv4/tcp_fin_timeout.

        errno: 13

        Permission denied

Error - can't open /proc/sys/net/ipv4/tcp_max_syn_backlog.

        errno: 13

        Permission denied

Error - can't open /proc/sys/net/ipv4/tcp_tw_reuse.

        errno: 13

        Permission denied

Error - can't open /proc/sys/net/ipv4/ip_local_port_range.

        errno: 13

        Permission denied

I have modified the /etc/sysctl.conf file to include the following:

Code:

# Settings for Domino

net.ipv4.ip_local_port_range = 1024 65535

fs.file-max = 131072

net.ipv4.tcp_fin_timeout = 15

net.ipv4.tcp_max_syn_backlog = 16384

net.ipv4.tcp_tw_reuse = 1

However, when I run the command 'sysctl net.ipv4.ip_local_port_range' I get the following instead:

Code:

net.ipv4.ip_local_port_range = 32768 61000

I have tried the following but keep getting permission denied errors:

Code:

echo 1024 65535 > /proc/sys/net/ipv4/ip_local_port_range

-bash: /proc/sys/net/ipv4/ip_local_port_range: Permission denied

Everything, apart from the running of the Domino server, is being run as the root user so don't understand why I should get permission denied errors.

Anyone seen this before and can help?

Thanks.
Pete.
