with open('read.txt', 'r') as fr:
    with open('write.txt', 'w') as fw:
        pre_line = ""
        line = "test"
        filelines = []
        while line != '':
            line = fr.readline()
            if line != pre_line:
                filelines.append(line)
            pre_line = line
        fw.writelines(filelines)
        fw.close()
        fr.close()

filelines에 모두 밀어 넣고 한번에 writelines로 처리했는데 이는 하나씩 writeline으로 처리해도 될 듯 하다.

필요에 의해서 만든 코드인데 read.txt내에 연속으로 중복되는 문자열을 제거하여 write.txt에 저장하는 코드다.

If the client and server are unable to agree on a mutual set of parameters then the connection will fail. OpenSSH (7.0 and greater) will produce an error message like this:

For the case of the above error message, OpenSSH can be configured to enable the diffie-hellman-group1-sha1 key exchange algorithm (or any other that is disabled by default) using the KexAlgorithms option - either on the command-line:

or in the ~/.ssh/config file:

OpenSSH 7.0 이상에서는 해당 옵션이 기본으로 enable 되어 있지 않기 때문에

옵션을 넣어줘야 한다.

항상 넣기 귀찮으니 config를 만들어서 넣고 쓰도록 하자.

config파일이 없으면 그냥 생성하면 적용 됨.
