ssh problem after upgrade

well at least your problem is solved. about the off topic yes i could make a guide but for various reasons I won't. One of of them is there will be too many support question coming and no control over stability of the firmware. maybe I change my mind in the future ;)

well, as I really need the compiler, could you at least tell me the target arch i need to use please?? :please :please

thats no problem , you can also see it in output of dmesg... ARMv5TE

be aware that cross compiling is not easy and fail free....mainly because of dependencies of the package you are going to compile
It will need to be compiled against shared libraries on the nas and not on the host system. There are more drawbacks

Thank you for the hint, I will keep it in mind... However to avoid this kind of troubles i think most of the times I will do a static compile...thank you very much!
