Whether IDA can set memory breakpoint when use Remote Linux debugger?

[Storm Shadow]

Yes its possible, there are some ways.
If adress is known you can set them when debugging and restart.
Or if its a condition, make new breakpoint and under condition file set future condition, and breakpoint type.
i like the script way, but thats just me.

simple BP script

ea = GetEntryPoint(1) # entrypoint or adress
ea2 = MaxEA
LoadDebugger("gdb", 1) # typedebugger and remote
AddBptEx(0x020000, 0x1, BPT_BRK) #adress or condition, lenght 
SetDebuggerOptions(DOPT_BPT_MSGS) #debugger atributes
path = GetInputFilePath()
args = ''
sdir = ''
StartDebugger(path, args, sdir)
