Hi all -
Just wondering if there is any way to protect an IP address against accidental deletion in RoS? Really my only concern is the IP that's used for management of the router itself. If that was accidentally deleted, the result is no management unless you are right there and can console in (I am not), and since all client allocations are routed to that IP, no routing either! Right now all one has to is highlight the router's IP in windbox and click the delete icon.
Is there anything like a read-only bit that can be set on the entry, or perhaps it can be password-protected?
Re: Protect an IP against accidental deletion
There's currently no way to set read-only attribute for specific sub-menus in RouterOS.
You could however create a script to run via scheduler to insure the proper settings are always in-tact. This should protect against accidental deletion by re-creating/re-setting settings to their "default" value.

Re: Protect an IP against accidental deletion
No, not really. However, you should use safe mode (ctrl-x) when working with your router, since that will reverse any changes if you do not log out properly...
Also, you can mostly rescue routers with mac-telnet if you accidentally remove their ip address.

Re: Protect an IP against accidental deletion
Thanks for weighing in. Mac-telent and -winbox apparently only work between two routers, and though the docs do not say so, I suspect they would have to be on the same L2 network in order for it to work. That does not help me or anyone else who has a single RoS device running in a remote location accessible only by TCP/IP. I understand safe-mode, but I don't think that's going to help if the router's 'primary' IP is deleted, as contact would immediately be lost.
I guess I'll post this in the feature suggestion area, unless anyone else knows of something that can be used to protect critical configs from accidental deletion.

Re: Protect an IP against accidental deletion
You are right about mac telnet. It only works between routers on the same broadcast domain.
If you are really worried about deleting this interface, I suggest you write a script, that you run at set intervals that checks if the ip address is present, and creates it if it's missing...

Re: Protect an IP against accidental deletion
I would go with read only for people you are concerned about. Other than that you can always use safe mode, & mac-telnet should some things go wrong.
