SSHv2 Cisco and MAC algorithm #373

Closed shinji7800 closed 1 month ago

shinji7800 commented 1 month ago

Hello there,

since I updated Cisco switch, only hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com are available

before upgrade : hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com, hmac-sha2-256,hmac-sha2-512,hmac-sha1 was compatible.

there Is a way to add missing algo in teraterm ?

thanks for your responses

best regards

Hi,

SSH client cannot use MAC algorithms which is not supported by remote server. Server (CISCO) seems to decided to drop support hmac-sha2-256,hmac-sha2-512 and hmac-sha1 MAC algorithm by default. Tera Term (TTSSH) supports hmac-sha2-256-etm@openssh.com and hmac-sha2-512-etm@openssh.com, I believe Tera Term can connect to CISCO. Does Tera Term have to add the MAC algorithms? What are you asking of us?

Thanks,
