SSH a poblem po aktualizaci na 20.04
« kdy: 22 Prosinec 2020, 22:51:26 »
Zdravím, mám problém, mám v lokální síti dva posítače s ssh, u jednoho jsem zjistil velký provoz(viz. níže), na druhém vše OK. Obě sshd běží  na linuxu na dvou stanicích (jeden ubuntu 20.10 (bez problémů) a jeden 20.04(s velkým provozem)), oba na portech 22.  Z vnější sítě jeden přesměrovánám z vnějšího portu 2222 na 22. Dosud vše běhalo bez problémů, problém nastal až po aktualizaci NTB z ubuntu 18.04 na 20.04), ze kterého se připojuji.
Po akualizaci   NTB mi to hlasí "unkown service" přes port 2222 -22, pokud port 2222 nechám 22 a počítače přehodím (vnitřní IP) tak mi to nefunguje na tom 2222, ale na druhém to pak běží OK. Používám tunel ssh pro RDP pře reminu. Přes vnější port 2222 to nejde, přes 22 ano, ale někdy až na několikátý pokus.
Co se týče provozu, mám root disabled, ale stejně mě přijde ten provoz velký, a nevím, proč jsou ty ataky na jeden PC. Na obou počítačích mi běží xampp, jeden mám přesměrovaný i pro připojení z venku (ten na kterém je problém).  Ne jednom (ten PC bez problémů)  ještě běží OPENVPN, ale to by neměl být problém.
Používám modem od O2 Archer MR200, ten moc zabezpečení nepoužívá...
Asi by bylo řešení to ssh  xamp pro vnější prostředí zavřít a nechat pouze pro local, a nechat pro vnější jenom OPENVPN, případně co mám dělat...
Díky Hyp
