linux - Cannot connect to host by SSH -


cannot connect host ssh.

i using following shell script use ssh.

host_list="c15-0330-14.ad.mtu.edu" ssh "$host_list"

but says : name or service not knownname c15-0330-14.ad.mtu.edu.

i tried ssh c15-0330-14.ad.mtu.edu. works. also, if have several hosts, how can invoke them 1 one?

the error message should be

ssh: not resolve hostname c15-0330-14.ad.mtu.edu: name or service not known

except dos line endings in script cause carriage return stored @ end of value of host_list. carriage return, when printed part of error message, causes cursor return beginning of line, resulting in error message see. notice how 2 halves line (the carriage return precedes colon):

ssh: not resolve hostname c15-0330-14.ad.mtu.edu : name or service not known

results in error of

: name or service not knownname c15-0330-14.ad.mtu.edu

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
