Configuration of mirror server for Signature update
NetBackup Malware Scanner (Avira) mirror server must be configured for signature update only when scan host does not have access to internet.
Creating local mirror server
- A designated host with NetBackup Malware Scanner must be installed.
- Login with the same user credentials used to install the NetBackup Malware scanner and run the following command:
cd $NB_MALWARE_SCANNER_PATH
./avupdate.bin --mirror --config=avupdate-savapilib-product.conf --install-dir=<update_path>
- Publish the <update_path> over HTTP.
For example, https://<local_mirror_server>/<update_path>.
Note:
Periodically run ./avupdate.bin --mirror command to keep the signature data up-to-date on the mirror server.
Using local mirror server during signature update
- The
update.sh
script refers toavupdate-savapilib-product.conf
file which is at the same location as that ofupdate.sh
, that is$NB_MALWARE_SCANNER_PATH
. - Update the
internet-srvs
entry in .conf file to point to the URL served by the local mirror server mentioned above.~/savapi-sdk-linux64/bin> cat avupdate-savapilib-product.conf #This configuration updates the entire SAVAPI Library (binaries, engine, signatures) #internet-srvs=https://oem.avira-update.com/update internet-srvs=https://<local_mirror_server>/<update_path> master-file=/idx/master.idx product-file=/idx/savapi4lib-linux64-en.info.gz install-dir=./ temp-dir=./tmp check-product
- Run the
update.sh
script to ensure that the update is working correctly.The
avupdate.log
file displays the following entries:~/savapi-sdk-linux64/bin> head avupdate.log 18/09/2022 23:31:47 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Avupdate Version: 2.6.10.36 18/09/2022 23:31:47 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Operating System: LINUX X86_64 5.3.18-22-DEFAULT 18/09/2022 23:31:47 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Installation Directory: . 18/09/2022 23:31:47 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Backup Directory: ./avupdate_backup 18/09/2022 23:31:47 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Temp Directory: ./tmp/avupdate_tmp_njoOb5 18/09/2022 23:31:47 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Cache Modules Directory: ./idx 18/09/2022 23:31:47 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Proxy settings: Direct connection 18/09/2022 23:31:47 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Downloading https://local_mirror_server/<update_path>/idx/master.idx to ./tmp/avupdate_tmp_njoOb5/idx/master.idx 18/09/2022 23:31:48 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Downloading https://<local_mirror_server>/<update_path>/idx/savapi4lib-linux64-en.info.gz to ./tmp/avupdate_tmp_njoOb5/idx/savapi4lib-linux64-en.info.gz 18/09/2022 23:31:49 pndch32bl10-09 avupdate.bin[10929]: UPD: INFO: Downloading https://<local_mirror_server>/<update_path>/idx/xvdf.info.gz to ./tmp/avupdate_tmp_njoOb5/idx/xvdf.info.gz
