I'm getting following error while connecting to hive database configured with Kerberos using Python pyhive module.
kerberos_service_name should be set if and only if in KERBEROS mode
My Connection code:
import hive from pyhive
con = hive.Connection(host="hostnamexxxxx",port=10001,
database="db_namexxxx",username="usernamexxxx",
auth="KERBEROS",
kerberos_service_name="hive")
Full Error Trace:
File "/xx/xx/site-packages/pyhive/hive.py", line 126, in __init__
raise ValueError("kerberos_service_name should be set if and only if in KERBEROS mode")
ValueError: kerberos_service_name should be set if and only if in KERBEROS mode
Also tried changing the kerberos_service_name to 'attuid#principal' but no luck.
could you please help!
Thanks in advance
Just was troubleshooting further the error was raised on line.
if (kerberos_service_name is not None) != (auth == 'KERBEROS'): raise ValueError("kerberos_service_name should be set if and only if in KERBEROS mode").
so check the auth output and as I was getting the authentication value from config parser it was including the quotes in word 'KERBEROS' and hence was returning false when compared with string 'KERBEROS'
i.e. 'KERBEROS' == ''KERBOROS''

I am trying to connect to a secure FTP server created based on this link. I have not followed step 8 in the link. I am able to establish the connection and also change and print directories but am unable to create new directories. I am also unable to fetch files list.
Here is my code snippet:
import ssl
from ftplib import FTP_TLS
import sys
import os
import os.path
def connect():
ftp = FTP_TLS()
ftp.debugging = 2
ftp.connect('ipaddress', 21)
ftp.set_pasv(False)
ftp.login('user', 'passwd')
return ftp
ftps = connect()
destdir = "/"
try:
resp = ftps.pwd()
ftps.cwd(destdir)
except Exception:
ftps.mkd(destdir)
print(resp)
root = 'C:\\Users\\****\\****\\Logs' # local dir
for (dir, _, files) in os.walk(root):
newdir = destdir+dir[len(root):len(dir)].replace("\\", "/")
print(newdir)
try:
ftps.cwd(newdir)
except Exception:
ftps.mkd(newdir)
I am using python 3.7.3 and the corresponding ftplib. I would be happy to provide any other details required.
PS: I am able to connect with Filezilla and create directories.
This is the error after running.
I am able to create the directories successfully once I change the dir to /logs. I am getting an error "ftplib.error_perm: 500 Illegal PORT command." whenever I send cmd like retrlines or storbinary
, I get this error
I have searched about this and people have asked to set it to pasv mode. When I do that, I get this error. FYI, I have enabled pasv mode in the config file
I tried changing the port number to a number between pasv ports enabled in the config file (between 30000-31000). It does not connect also in this case. Error returned "ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it"
I am working the first time with an FTP server or for that matter any server communications, so my problems might seem trivial. I am sorry for your trouble.
Thanks.
I want use the python library ncclient 0.6.6 with Python 2.7.15 to connect to a NETCONF server (netopeer2) and read out the running config.
I tried to follow the example from the manual, running this code in the console:
with manager.connect(host="*the IP adress*", port=*the port*, timeout=None, username="*user*", password="*pwd*") as m:
c = m.get_config(source='running').data_xml
with open("%s.xml" % host, 'w') as f:
f.write(c)
As written in the manual, I try to disable public-key authentification with allow_agent and look_for_keys as False. Unfortunately, this does not work properly, because I get the error message:
File "<stdin>", line 1, in <module>
File "/home/sisc/.local/lib/python2.7/site-packages/ncclient/manager.py", line 177, in connect
return connect_ssh(*args, **kwds)
File "/home/sisc/.local/lib/python2.7/site-packages/ncclient/manager.py", line 143, in connect_ssh
session.connect(*args, **kwds)
File "/home/sisc/.local/lib/python2.7/site-packages/ncclient/transport/ssh.py", line 481, in connect
raise SSHUnknownHostError(known_hosts_lookup, fingerprint)
ncclient.transport.errors.SSHUnknownHostError: Unknown host key [e3:8d:35:a9:43:f9:3c:8a:f4:d3:88:5b:a9:36:93:59] for [[192.168.56.2]:1831]
I do not get why it still complains about the unknown host key, even though I explicitly disabled public-key authentification.
The netopeer NETCONF server is definitely running, for I get a "Hello" Message as soon as I try to SSH into it from out of the terminal.
Did I miss something?
m = manager.connect(host="172.17.0.2", port=830, username="netconf", password="netconf", hostkey_verify=False)
Did the trick. Hostkey_verify has to be false.
when connecting to a hive-server without authenticate, it works fine, like this:
conn = connect(host='host.without.authenticate.', port=xxx, database=xxx, auth_mechanism='PLAIN')
when connecting to a hive-server with ldap authenticate as follow, occurs the sasl error.
Could not start SASL: Error in sasl_client_start (-4) SASL(-4)
I have installed saal and thrift-sasl, and can login in hive by shell:
conn = connect(host='host.with.ldap.authenticate.', port=xxx, database=xxx, auth_mechanism='LDAP', user=xxx, password=xxx)
Configuration: ubuntu 14, python2.7
I have visit the issue https://github.com/cloudera/impyla/issues/149 but no applicable methods
I don't know what's wrong, and appreciate for your answers
This function should connect to database because I've used an exception I'll get my own created message, when incorrect input is found. But when I remove try and except I get : "Acces denied for /'user/'#'/'localhost' (using password : NO).
It seems that it doesnt read my password I have no clue why a little help will be appreciated. Without this file connection to the database works fine without any errors.
try:
self.conn = pymysql.connect(read_default_file="~/my.cnf")
self.curr = self.conn.cursor()
except pymysql.err.OperationalError :
sys.exit("Invalid Input: Wrong username/database or password found, please try again")
Information found in the .my.cnf file is :
[client]
host = 'localhost'
port = 3306
user = myusername
password = "mypassword"
You used:
pymysql.connect(read_default_file="~/my.cnf")
You should have used:
pymysql.connect(read_default_file='~/.my.cnf')
-------------------------------------^
Note the missing dot in the filename. You were just loading a different or non existent file.
The ~ is being expanded as shown here:
https://github.com/PyMySQL/PyMySQL/blob/18b62f6e1d6f65b403c9e8b650f4c3bb27b665e7/pymysql/connections.py#L619
Also I can confirm that no quotes or spaces are required in the .my.cnf file:
echo -e "[client]\nuser=root\npassword=defaultrootpwd" > ~/.my.cnf
First off, can you connect to your database using the following command.
import pymysql
conn = pymysql.connect(host='localhost',
port=3306,
user='myusername',
passwd='mypasswd')
If that doesn't work, then you might have some other problem (for instance, your database may be configured to only connect via socket for local clients)
As for the config file, I think this will work if you remove the quotation marks, like this:
[client]
host = localhost
port = 3306
user = myusername
password = mypassword
I saved your config file as test.cnf and ran the following code
# test.cnf
[client]
host = 'localhost'
port = 3306
user = myusername
password = "mypassword"
$ python3
>>> import configparser
>>> reader = configparser.RawConfigParser()
>>> reader.read('test.cnf')
>>> reader.get('client', 'host')
"'localhost'"
>>> reader.get('client', 'user')
'myusername'
As you can see, the config parser is treating quotes as part of the value.
Update: Workaround
The OP mentioned the provided solution (i.e. removal of quotes did not solve the problem he was facing). Here's a workaround that achieves separation of configuration / connection properties from program logic.
Save the configuration in a python file called dbsettings.py.
# dbsettings.py
connection_properties = {
'host': 'localhost',
'port': 3306,
'user': 'myusername',
'passwd': 'mypassword'
}
And then in your main program use the following lines for setting up the connection.
try:
from dbsettings import connection_properties
self.conn = pymysql.connect(**connection_properties)
self.curr = self.conn.cursor()
except pymysql.err.OperationalError :
sys.exit("Invalid Input: Wrong username/database or password found, please try again")
If your entire program is written in python, then this allows the same separation of connection / config info from program logic as using the my.cnf method, and it is just as flexible if not mroe so. However, if other non python scripts need to reference the my.cnf file, then you'll have to maintain two separate mysql config files.
When sendmail is configured with password that starts with the character #, authentication is failed. Sendmail throwed an error that "AUTH=client, available mechanisms do not fulfill requirements".
Is this is a known issue.?
Is that a restriction with sendmail or ssl authentication or rules parsing?
Sample default-auth-info file :-
sendmailtest#gmail.com
sendmailtest#gmail.com
#12345678
smtp.gmail.com:587
LOGIN PLAIN DIGEST-MD5 CRAM-MD5 NTLM
LINUX platform
Sendmail version : 8.14.0
sasl version : 2.1.22
Thanks in advance for the help..
It seems that readauth function in sendmail/usersmtp.c file ignores lines starting
with #.
BTW Have you considered using FEATURE(authinfo) instead of confDEF_AUTH_INFO/DefaultAuthInfo?
Anyway makemap command also by default treats # as a comment indicator but it may be changed using -D command line option.
