        Parameters:
        keepAliveProvider - keep-alive provider

      • isWaitForServerIdentBeforeSendingClientIdent

        public boolean isWaitForServerIdentBeforeSendingClientIdent()
        Description copied from interface: Config
        Gets whether the client should first wait for a received server ident, before sending the client ident.

        NB: This is non-standard behaviour, and can potentially deadlock if the server also waits on the client ident. The default value is set to false.

        Specified by:
        isWaitForServerIdentBeforeSendingClientIdent in interface Config
        Returns:
        Whether to first wait for the server ident.

      • setWaitForServerIdentBeforeSendingClientIdent

        public void setWaitForServerIdentBeforeSendingClientIdent​(boolean waitForServerIdentBeforeSendingClientIdent)
        Description copied from interface: Config
        Sets whether the SSH client should wait for a received server ident, before sending the client ident.

        NB: This is non-standard behaviour, and can potentially deadlock if the server also waits on the client ident.

        Specified by:
        setWaitForServerIdentBeforeSendingClientIdent in interface Config
        Parameters:
        waitForServerIdentBeforeSendingClientIdent - Whether to wait for the server ident.

      • setLoggerFactory

        public void setLoggerFactory​(LoggerFactory loggerFactory)
        Description copied from interface: Config
        Sets the LoggerFactory to use.
        Specified by:
        setLoggerFactory in interface Config

      • isVerifyHostKeyCertificates

        public boolean isVerifyHostKeyCertificates()
        Description copied from interface: Config
        Returns true if host key certificates should be verified while connecting to the server. It is recommended to verify them, but can cause connection failures in cases when previous versions of the library could have managed to connect.
        Specified by:
        isVerifyHostKeyCertificates in interface Config

      • prioritizeSshRsaKeyAlgorithm

        public void prioritizeSshRsaKeyAlgorithm()
        Modern servers neglect the key algorithm ssh-rsa. OpenSSH 8.8 even dropped its support by default in favour of rsa-sha2-*. However, there are legacy servers like Apache SSHD that don't support the newer replacements for ssh-rsa. If ssh-rsa factory is in getKeyAlgorithms(), this methods makes ssh-rsa key algorithm more preferred than any of rsa-sha2-*. Otherwise, nothing happens.
