MON-12663 | A few customers have reported that their security solutions are flagging the package masscan-1.0.3-5.el7.x86_64.rpm as suspicious, hence preventing its download when updating OP5 Monitor. In OP5 Monitor, Masscan is used by Nacoma for service discovery on hosts in the monitored network, by scanning and detecting open ports. The full repository path to the package is http://repos.op5.com/epel/7/x86_64/Packages/m/masscan-1.0.3-5.el7.x86_64.rpm Whitelisting the package should resolve the issue. |

OP5 Monitor 8.0.8 Copied
Released: 15 October 2019
To download ITRS OP5 Monitor, including all components, see ITRS Downloads.
These are the highlights of this release:
- It has always been recommended to only restore the same version where the backup was taken from. To restore a backup from different versions of OP5 Monitor can cause serious issues. In this release, a thorough version check has been implemented for the restore of backups that prevents all restore except the exact same version.
- In the past, OP5 Monitor has filtered out SNMP results where the
ifDescr
field has been containing the wordsnull
orloopback
. This filtering has caused issues for some customers, hence the filtering has been removed. Each customer can now decide on how to use this information.
