J2SSH支持的密码/ Mac

Question

I am running a java application which uses J2ssh library to establish the connection to the server. Last week we migrated to a new IBM server

Here the problem is we are unable to establish FTP/SFTP connection to the new server from my java application. But the connectivity is working fine from other tools.

My doubt is whether the J2SSH library will support the below ciphers/macs ? because these are the ciphers configured in the new IBM server.

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128
MACs hmac-sha1,umac-64@openssh.com,hmac-ripemd160

Answer 1

It sounds like your using a very outdated version of J2SSH.

You should upgrade to the more recent open source version J2SSH Maverick that supports counter mode ciphers.
