I would like to save to file all my output from ssh connection(s). The ssh connection works fine, the output is ok too to a stdout. I want to create a file for every connection individually in a file. I have changed the output lines to the lines below and also moved it above
output_filename = ip_address + ".txt"
file = open(output_filename, 'w')
file.write(output.decode)
file.close()
What is missing?
I receive this error:
line 100, in fractal
except 10060:
TypeError: catching classes that do not inherit from BaseException is not allowed
And it just don't save the output. the file is created, but in blank.

This happens only in Python3, because except now expects a class that is a subclass of BaseException. And the integer 10060 is not.

ValueError
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 3, in <module>
TypeError: catching classes that do not inherit from BaseException is not allowed
So Paramiko is raising some other error, but error handling dies when it tries to evaluate the except 10060 statement.

When I try to use these on separate PCs and use public IP addresses it won't connect. The server I bind to 0.0.0.0 and then use the public IP address of the server's computer to the client code. I imagine I am doing something fairly obvious wrong. If anyone can help, it would be very much appreciated.
I am trying to use some code to read username and password from a file called ".logon" and establish a connection to redshift. But I got the error message "Python - Warning: Unexpected Error: ".
Here is my code:
def redshift_connect():
try:
l_user = getpass.getuser()
home = expanduser("~")
f = open(home + '/.logon')
logline = f.readline()
usr = logline.split(',')[0].split('/')[1].strip()
pwd = logline.split(',')[1].rstrip()
conn=psycopg2.connect(host='host-name',
port= 5439, user= usr, password= pwd)
return conn
except IOError as e:
print ('I/O error ({0}): {1}: .tdlogon missing!!'.format(e.errno, e.strerror))
except:
print ('Warning: Unexpected Error:',sys.exc_info()[0])
else:
raise ConnectionError('Cannot establish connectionw with Redshift.')
I guess the expression logline.split(',') works and returns an array with only one entry. The expression logline.split(',')[1] then raises an IndexError which you catch in the unspecific except clause.

I do not have a lot of experience with python, so it would be very nice of you to check my code.

In the downloadf function and exactly in this code part

The problem was that i used the same ftp connection instance through, xftp = self.get_conn() and that is why i got errors that didn't seem to describe the source problem, how matter what changes did i introduce to my code to fix that.
The solution is to instantiate a new ftp connection for each process, so instead of the above line of code i do the folloying now: xftp = ftplib.FTP()
Maybe there is a kind soul that could bring a more 'pythonic' explanation to this issue. I would be gratefull
I am trying to SSH into a bunch of routers and grep some info from each. Some of the router IPs might not be valid as they are got from the loop. For the ones that do not exist, i am getting a socket.timeout error (obviously) and the script exits execution at that point. I want python to ignore this error and continue with the rest of the iterations. I have included the except/pass/continue commands, but they somehow do not seem to be doing their job and i am still getting the socket.timeout error and exiting the script :
