Automated Backup Solution

Hello All, I am trying to set up following auto backup solution found here - https://devcentral.f5.com/wiki/iApp.Complete-F5-Automated-Backup-Solution.ashxDescription_1?NS=iApp

 

I have followed everything created the key as documented and I have tested from F5 CLI and I was able to SFTP and SCP without password (I selected the option backup on this f5).

 

However when I use the GUI and select the option SFTP or SCP it requires me to put in "Enter the SSH private key to be used for passwordless authentication" and "Set the remote directory the archive should be copied to"

 

So the question is for SSH private key do I get that from /root/.ssh/id_rsa ? and do I copy paste the entire key? Also for destination does it use "/" or "\".

 

Lastly where is log kept of this iAPP? I have looked almost everything couldnt find it?

 

Please help.

 

Thanks

I have found the logs, and what I can see in there as follows: Permission denied, please try again. Permission denied, please try again. Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).

The key you are looking for should be /config/ssh/ssh_host_dsa_key

 

Hi Cory, I know where to find the key but how do I copy paste the content of the file in txt box as there is no way for me tell whether entire is has been uploaded there or not. Thanks

You can print to screen the private key using cat. cat /config/ssh/ssh_host_dsa_key

Hi Cory, I have done that before I am still getting the same error.... and shouldn't it be the RSA key .... ? Anyway I have used the RSA private key which didnt work ? Any other idea? Thanks

I'm pretty sure the system uses the ssh_host_dsa_key for system connections. We have an external monitor that connects via SSH to pool members and runs a script, and it uses the ssh_host_dsa_key private key for authentication to the pool members. You would then load the corresponding public key (ssh_host_dsa_key.pub) on your target machine.

I used ssh-keygen -t rsa to generate a new keypair and it is saved in /root/.ssh/id_rsa. You need to import id_rsa.pub in authorized_keys file of the receiving sftp server host in $HOME/.ssh. Make sure that you have the appropiate read rights on the receiving server to this file.

Also I used the following scripts to automate backup using SFTP and the sent an email if the upload failes. The local created backup files are automatically on the Big IP to save disk space.

 

!/bin/bash

DATE=date "+%m_%d_%y"

 

Here we create the ucs archive and append the date

tmsh save sys ucs bigip.backup.$DATE

 

upload SFTP to SFTP_server

cd /var/local/ucs/ sftp backupuser@SFTP_server <

 

check if the upload has succeeded or failed. If failed mail error message

if [ $? -eq 0 ] then sleep 5 rm /var/local/ucs/bigip.backup.$DATE.ucs else ftp session failed mail -s "ftp backup file failed from BigIP" mail@mail.com < /dev/null fi

Hi! I just want to share a simple backup solution. Try doing this (source: ">http://www.linuxproblem.org/art_9.html" target="_blank">">http://www.linuxproblem.org/art_9.html😞

 

ssh-keygen -t rsa

Then you can give my script a try: ">https://github.com/rileyschuit/bash-tools/blob/master/bigip_backups.sh" target="_blank">">https://github.com/rileyschuit/bash-tools/blob/master/bigip_backups.sh

 

Adjust the array to point to your management addresses they use the argument "setup" to copy the public keys in the right place. Adjust the target directory as well, if needed.

 

Thank the devcentral WYSIWYG for making my post super ugly....
