If you experience version related issues, then please send supout file from your router to [email protected]. File must be generated while router is not working as suspected or after some problem has appeared on device

Please keep this forum topic strictly related to this concrete RouterOS release.

If you router has a storage issue (not enough space due to RouterOS, not by other files stored on the device), use package from this link:

https://www.mikrotik.com/download/share/fix_space.npk
- upload package to your router; - run /system reboot Other affected installations will be fixed automatically, if there is enough space left for an upgrade by this fix: "package - free up used storage space consumed by old RouterOS upgrades"
v6.42.7 [current] is released! - MikroTik

bridgeインターフェースのステータス変更の際のプロセス周りの変更や、CRS3xxシリーズでのVLAN周りの動作修正が入っています。
また、DHCP周りもdistance値が変更できるようになるなどの修正が入っています。

あとは以前からあった、空き容量の認識がおかしくなりPackageのアップデートができなくなる問題ですが、改善用のパッケージが別途公開になっています。この問題が発生している方は適用してみてください。

筆者の環境でのmipsbeの機器への適用を行いましたが、問題は発生していません。

なお、別件で発生している、WPA2 Keyへのブルートフォースアタックをすることでパスフレーズの取得ができる問題ですが、以下のスレッドで説明が行われています。

WPA2 preshared key brute force attack - MikroTik

testingリリースとなりますが、RouterOS 6.43rc56で以下のように更新が行われています。

What’s new in 6.43rc56 (2018-Aug-13 11:13):

*) wireless – added option to disable PMKID for WPA2 (CLI only);

https://forum.mikrotik.com/viewtopic.php?f=21&t=137838#p679904

以下のように設定を行うことで、今回の原因となっているPMKIDを無効にできるようです。

/interface wireless security-profiles add disable-pmkid=yes 
# または、
/interface wireless security-profiles set disable-pmkid=yes [find]

ただし適用すると、他にどのような影響があるのか筆者は確認していません。適用する際は実際にテストを行い、以前まで接続を行っていた機器の接続に問題がないか確認するようにしてください。
