Is it possible if i upgrade from ROS V5.26 to ROS v6.7 directly ?
yes!
strange. just upgraded 2 RB2011RM-s, both of them were running 5.24.
both of them died on the spot.
the config was plain and very simple, just a static default and a fixed ip address on eth1.
no fw, no nothing. ok, i had to admit, both had dude4.0b3 installed and enabled on them.
one was able to boot, and ssh was connecting, but after authentication (or better said after 10-15 seconds if i did
not try to ssh in it) it rebooted itself. routerboot was upgraded to 3.10 before the upgrade.
and it just went up and down, in infinite loop. even the console was nothing of use, cause after the password
prompt it just rebooted.
i had to netinstall, and then it came back to life. (which involved a lot of runaround with some windows laptop though)
the second one was stopped at "loading kernel". i power cycled it, and it booted perfectly.
in both cases i had remote access via console, but it didn't help lot
BTW: is there a way to boot routerOS from a tftp server using dhcp? i successfully assigned ip address using dhcp to
the rebooted device, also sent the DHCP server parameters, but it always looked for "vmlinux". and i did not found
any way to somehow extract it any of the .npk files.
or is it just the netinstall tool running on windows, my last hope for survival?
it's probably just me only, but i don't have windows installations floating around my production network, accessible from the local L2,
i rather do stuff from *nix. and yes, i thing wine and lookalikes are a real PITA.
wouldn't be possible to offer a standalone bootable kernel with embedded ramdisk only capable for some ip host operations and a tftp/ftp/http client?
and then: dhcp to get IP, tftp to boot this "bootstrap kernel" from a DHCP option specified TFTP server, through the console
access the device, set temporary IP, download via tftp/ftp/http, then reboot.
