What should I do when I want to add lines of duplicated port to /etc/services?

Solution Verified - Updated -

Issue

  • I'd like to install a third party software on our server. The software requests to add lines like below on /etc/services.

    netmdm    30000/tcp # NETM/DM
netmdmw   30001/tcp # NETM/DM
netmdmclt 30002/tcp # NETM/DM
netmdmclt 30002/udp # NETM/DM

  • However, these ports has already used by 'pago-services'.

    # grep 3000[0-9] /etc/services
pago-services1  30001/tcp                       # Pago Services 1
pago-services1  30001/udp                       # Pago Services 1
pago-services2  30002/tcp                       # Pago Services 2
pago-services2  30002/udp                       # Pago Services 2

  • I'd like to remove 'pago-services' lines if it would be safe.
