RFC 4253 dice di SSH:
6.1. Maximum Packet Length
All implementations MUST be able to process packets with an uncompressed payload length of 32768 bytes or less and a total packet size of 35000 bytes or less (including 'packet_length', 'padding_length', 'payload', 'random padding', and 'mac'). The maximum of 35000 bytes is an arbitrarily chosen value that is larger than the uncompressed length noted above. Implementations SHOULD support longer packets, where they might be needed. For example, if an implementation wants to send a very large number of certificates, the larger packets MAY be sent if the identification string indicates that the other party is able to process them. However, implementations SHOULD check that the packet length is reasonable in order for the implementation to avoid denial of service and/or buffer overflow attacks.
Non dice quale dovrebbe essere la lunghezza massima del pacchetto, ma consiglia che la lunghezza sia "ragionevole".
Le implementazioni Cisco hanno una lunghezza massima del pacchetto di 35000 byte; qualsiasi cosa più grande viene eliminata.
Ho provato googling per un'impostazione simile in OpenSSH ma è uscito vuoto.
OpenSSH ha un tale limite?
