# This is the sshd server system-wide configure file. See # sshd_config (5) for more information.

# This sshd Was compiled with path = / usr / bin: / bin: / usr / sbin: / sbin

# The strategy used Uncommented options change a # default value for options in the default sshd_config shipped with # OpenSSH is to specify options with their default value where # possible, but leave them commented..

# Note That Some of FreeBSD's Defaults Differ from OpenBSD'S, and # Freebsd Has A Few Additional Options.

TIP ~

SSHD settings, please refer to the configuration file above SSH 21. Generate the keySH-KEYGEN -T DSA used by SSH2

2.cp id_dsa.pub to the remote host ~ / .ssh / under CAT ID_DSA.PUB >> ~ / .ssh / authorized_keysrm id_dsa.pubchmod 700 ~ / .ssh / authorized_keys

Do not use mv or CP to generate an Authorized_Keys file because it will make your other Pubkey lose authorized_keys can include multiple Pubkey3.SSH -I ID_DSA User @ HostName Connect Host Enter KEY passwords to connect to connect to connect SSH 2 Server SecureCRT Key and SSHD are incompatible, format issues need to convert identity.pub generated Pubkey conversion ssh-keygen -x -f iDENTITY.PUB> Identity.pub2 joose Authorized_KeysRM for secureCRT Identity.pub * You can connect the key pair generated by SecureCRT and the key generated by the SecureCRT, which can only know the format of its key, so that both can only know the format of their key, so they can use SecureCRT The OpenSSH connection is used to use their own key format. You can generate it with any method and then use SSH-Keygen -i to convert the key format generated by SecureCrt to OpenSsh, or use ssh-keygen -e OpenSSH's key format is converted to SecureCRT to identify IETF Secsh formats.
