channel output. The maximum number of channels supported by the audio AI and AO is 16 channels (where the hi3518/hi3516c chip is limited by the built-in codec, only 2 channels are supported), and the channel is configured to be even if the AI and AO devices are configured. The hi3518/hi3516c only supports 16bit bit width. The HI3518A/HI3518C/HI3516C provides a built-in audio Codec, and on the inside of the chip to the SIO0 interface, that is, the SIO0 interface only through the built-in audio C

Slow SSH connection in CentOS/Linux Currently, SSH remote connection is generally used to connect to the inux server. I recently installed a new server and found that telnet is fast, ping is normal, but SSH connection is slow. There are several reasons for the query: 1. The SERVER's SSHD will go to the DNS to find the HOSTNAME of the accessed client ip address. If the DNS is unavailable or there is no relevant record, it will take some time.2. In authentication gssapi-with-

). Check that the client's certificate is in the certificate revocation list (CRL).Attached: Common certificate format 1.1. PEMOpenSSL uses the PEM (RFC 1421-1424) document format. The PEM full name is privacyenhanced Mail, which defines the standard for encrypting a ready to send message. Its basic flow is this:1, the information is converted to ASCII code or other encoding method;2, using the symmetric algorithm to encrypt the converted message information;3, using BASE64 to encode the message

If you have any new ideas, you can discuss them together ~ There are no special instructions for
