mysqlcheck -o –all-databases

If you are offline then you can run myisamchk which is a little more thorough.

myisamchk –sort-index
myisamchk -r tbl_name

#!/bin/bash

max_size=”2097152″ # This is 2097152KB or 2GB

for u in `ls /var/cpanel/users/`;
do
size=$(repquota -a | grep ${u}|awk ‘{print $3}’|sort -k 1 -nr|head -1);
if [ "${size}" -ge "${max_size}" ];
then
echo “${u}” >> /tmp/cpbackup-userskip.conf;
fi;
done;

sort -u /tmp/cpbackup-userskip.conf /etc/cpbackup-userskip.conf > /tmp/cpbackup-userskip.conf.uniq;
cp -f /tmp/cpbackup-userskip.conf.uniq /etc/cpbackup-userskip.conf;
rm -f /tmp/cpbackup-userskip.conf.*;

history -c

which date

For most servers it is:

/bin/date

This is the same for perl and php

The bug spins the program over and over causing high memory and sometimes CPU use. Unfortunately there is no permanent fix yet, but if you see something like this high in your daily process log:

/usr/bin/python -E /usr/sbin/setroubleshootd

To fix for now you simply have to restart the process:

/etc/init.d/setroubleshoot restart

http://www.ezlinuxadmin.com/2009/08/upgrading-perl-on-cpanel/

After that if you still have a issue run this:

/scripts/perlinstaller –force YAML::Syck

or Install the YAML::Syck perl module in whm under module installers.

fsck -a

Will automatically fix errors.

Website Driver Download
Here is direct link to the driver from our website:

http://www.downloadspot.com/downloads/r8168-8.018.00.tar.bz2

Upload the driver to your root directory, then run these commands.

tar vjxf r8168-8.018.00.tar.bz2

cd r8168-8.018.00

./autorun.sh

Run this to check the driver details

dmesg | grep ‘Ethernet driver’

Read me files for driver:

<Linux device driver for Realtek Ethernet controllers>

This is the Linux device driver released for RealTek RTL8168B/8111B, RTL8168C/8111C, RTL8168CP/8111CP, RTL8168D/8111D, RTL8168DP/8111DP, and RTL8168E/8111E Gigabit Ethernet controllers with PCI-Express interface.

<Requirements>

- Kernel source tree (supported Linux kernel 2.6.x and 2.4.x)
- For linux kernel 2.4.x, this driver supports 2.4.20 and latter.
- Compiler/binutils for kernel compilation

<Quick install with proper kernel settings>
Unpack the tarball :
# tar vjxf r8168-8.aaa.bb.tar.bz2

Change to the directory:
# cd r8168-8.aaa.bb

If you are running the target kernel, then you should be able to do :

# ./autorun.sh    (as root or with sudo)

You can check whether the driver is loaded by using following commands.

# lsmod | grep r8168
# ifconfig -a

If there is a device name, ethX, shown on the monitor, the linux
driver is loaded. Then, you can use the following command to activate
the ethX.

# ifconfig ethX up

,where X=0,1,2,…

<Set the network related information>
1. Set manually
a. Set the IP address of your machine.

# ifconfig ethX “the IP address of your machine”

b. Set the IP address of DNS.

Insert the following configuration in /etc/resolv.conf.

nameserver “the IP address of DNS”

c. Set the IP address of gateway.

# route add default gw “the IP address of gateway”

2. Set by doing configurations in /etc/sysconfig/network-scripts
/ifcfg-ethX for Redhat and Fedora, or /etc/sysconfig/network
/ifcfg-ethX for SuSE. There are two examples to set network
configurations.

a. Fixed IP address:
DEVICE=eth0
BOOTPROTO=static
ONBOOT=yes
TYPE=ethernet
NETMASK=255.255.255.0
IPADDR=192.168.1.1
GATEWAY=192.168.1.254
BROADCAST=192.168.1.255

b. DHCP:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes

<Modify the MAC address>
There are two ways to modify the MAC address of the NIC.
1. Use ifconfig:

# ifconfig ethX hw ether YY:YY:YY:YY:YY:YY

,where X is the device number assigned by Linux kernel, and
YY:YY:YY:YY:YY:YY is the MAC address assigned by the user.

2. Use ip:

# ip link set ethX address YY:YY:YY:YY:YY:YY

,where X is the device number assigned by Linux kernel, and
YY:YY:YY:YY:YY:YY is the MAC address assigned by the user.

<Force Link Status>

1. Force the link status when insert the driver.

If the user is in the path ~/r8168, the link status can be forced
to one of the 5 modes as following command.

# insmod ./src/r8168.ko speed=SPEED_MODE duplex=DUPLEX_MODE autoneg=NWAY_OPTION

,where
SPEED_MODE    = 1000    for 1000Mbps
= 100    for 100Mbps
= 10    for 10Mbps
DUPLEX_MODE    = 0    for half-duplex
= 1    for full-duplex
NWAY_OPTION    = 0    for auto-negotiation off (true force)
= 1    for auto-negotiation on (nway force)
For example:

# insmod ./src/r8168.ko speed=100 duplex=0 autoneg=1

will force PHY to operate in 100Mpbs Half-duplex(nway force).

2. Force the link status by using ethtool.
a. Insert the driver first.
b. Make sure that ethtool exists in /sbin.
c. Force the link status as the following command.

# ethtool -s ethX speed SPEED_MODE duplex DUPLEX_MODE autoneg NWAY_OPTION

,where
SPEED_MODE    = 1000    for 1000Mbps
= 100    for 100Mbps
= 10    for 10Mbps
DUPLEX_MODE    = half    for half-duplex
= full    for full-duplex
NWAY_OPTION    = off    for auto-negotiation off (true force)
= on    for auto-negotiation on (nway force)

For example:

# ethtool -s eth0 speed 100 duplex full autoneg on

will force PHY to operate in 100Mpbs Full-duplex(nway force).

<Jumbo Frame>
Transmitting Jumbo Frames, whose packet size is bigger than 1500 bytes, please change mtu by the following command.

# ifconfig ethX mtu MTU

, where X=0,1,2,…, and MTU is configured by user.

RTL8168B/8111B supports Jumbo Frame size up to 4 kBytes.
RTL8168C/8111C and RTL8168CP/8111CP support Jumbo Frame size up to 6 kBytes.
RTL8168D/8111D supports Jumbo Frame size up to 9 kBytes.
