Not able to login to clickhouse.Can any one please look into it.
root#ubuntu:~# clickhouse-client
ClickHouse client version 20.8.2.3 (official build).
Connecting to localhost:9000 as user default.
Code: 516. DB::Exception: Received from localhost:9000. DB::Exception: default: Authentication failed: password is incorrect or there is no user with such name.
there are 3 possible reasons:
network restriction (in CH auth for this user).
no user with such name
password is incorrect
If you just installed CH , then you can edit/remove /etc/clickhouse-server/users.d/default-password.xml . This file stores the password you entered during CH installation.
It's simple:
do not use localhost / 127.0.0.1 but use external address
the following code works with a normal password
WebBrowser1.Navigate("http://username:Password#160.30.90.52/cgi-bin/statuspage.cgi ")
but my default password is p#ssword
WebBrowser1.Navigate("http://username:P#ssword#160.30.90.52/cgi-bin/statuspage.cgi ")
how can i let this code run with the # sign
i need to download files from a url programtically and all my code works all i still need is a way to pass the username and password to the url but the url password contaains that # sign
HI so it took a wile but finally found a answer
if you were to pass a username or password with certain special symbols like the # sign you need to do some Encoding on the symbols
instead of using p#ssword i now used p%40ssword and it worked heres my working code
WebBrowser1.Navigate(" https://username:p%40ssword#160.30.90.52/cgi-bin/statuspage.cgi ")
and here are some other symbols you guys might need in the future
! %21
[space] %20
# %40
$ %24
% %25
^ %5E
& %26
* %2A
( %28

I'm trying to figure out how to send my credentials to Gmail. RFC5034 gives an example
S: IMPLEMENTATION BlurdyBlurp POP3 server
S: .
C: AUTH PLAIN dGVzdAB0ZXN0AHRlc3Q=
S: +OK Maildrop locked and ready
and the base64 encoded string decodes to test\0test\0test where \0 is null character.
However, if I send a base64 encoded string like that username\0user#gmail.com\0password, then I get an error message like this
-ERR [SYS/TEMP] Temporary system problem. Please try again later. df2mb862702032iec
So, these are the combinations I've tried with their outcomes:
user\0password => -ERR invalid SASL argument 42mb45977297otf
user#gmail.com\0password => -ERR invalid SASL argument uz3mb206121874obc
\0user#gmail.com\0password => -ERR [AUTH] Username and password not accepted.
\0user\0password => -ERR [AUTH] Username and password not accepted.
name\0user#gmail.com\0password => -ERR [SYS/TEMP] Temporary system problem. Please try again later. df2mb862702032iec
\0name\0user#gmail.com\0password => -ERR invalid SASL argument h184mb244881255oib
So, it looks like it should be \0user#gmail.com\0password but if I base64 encode my email and password like this:
echo -ne '\0user#gmail.com\0password' | base64
My username and password are still rejected.
So, can someone confirm the correct method of base64 encoding? Oh, and I have Pop mail activated in my settings.
And the answer is that there's a bug with Gmail. Even though with pop3 enabled on my account (of 15Gb of email), it doesn't recognise my credentials.
I have another email account with my own domain on gmail with very little mail and using the base64 version of
\0user#domain.com\0password
works just fine where \0 represents the null character.
You need to enable "less secure apps" in your GMail settings:

I'm using the Debian image for the BBB from here: Debian (BeagleBone Black - 2GB eMMC) 2014-05-14
This image has the Cloud9 IDE built-in. It works quite nicely for my purposes, but I can't figure out how to add a password. Anyone on the network can go to 11.22.33.44:3000 (not the actual IP address) and the IDE will automatically log them in as "John Doe" (No password requested).
Is there a way to request a user name and password when logging into Cloud9? I'm ok if the browser saves the password, but it should ask at least once.
I just found out the solution.
To set a default username and password:
Open the file /opt/cloud9/build/standalonebuild/configs/standalone.js.
Locate the following code block. (Should be at the top of the file)
if (!optimist.local) {
optimist
.boolean("t")
.describe("t", "Start in test mode")
.describe("k", "Kill tmux server in test mode")
.default("b", false)
.describe("b", "Start the bridge server - to receive commands from the cli")
.default("w", config.workspaceDir)
.describe("w", "Workspace directory")
.alias("p", "port")
.default("port", process.env.PORT || config.port)
.describe("port", "Port")
.alias("d", "debug")
.default("debug", false)
.describe("debug", "Turn debugging on")
.alias("l", "listen")
.default("listen", process.env.IP || config.host)
.describe("listen", "IP address of the server")
.boolean("help")
.describe("workspacetype")
.alias("ws", "workspacetype")
.describe("readonly", "Run in read only mode")
.alias("ro", "readonly")
.describe("packed", "Whether to use the packed version.")
.boolean("packed")
.default("packed", config.packed)
.alias("a", "auth")
.describe("auth", "Basic Auth username:password")
.default("auth", ":")
.describe("collab", "Whether to enable collab.")
.default("collab", config.collab)
// #lennartcl this should be moved
.describe("lb.fileserver", "LogicBlox file server Url")
.default("lb.fileserver", config.logicblox && config.logicblox.fileServerURL);
}
At the line .default("auth", ":"), type in the username and password you'd like to use in the format of username:password, e.g. .default("auth", "user:pass")
You should be all set! Try accessing 11.22.33.44:3000, and there should be a pop-up prompting for username and password.
On a side note, if you wish to change the profile name (the default "John Doe"):
Open the file /opt/cloud9/build/standalonebuild/settings/standalone.js.
Locate the following code block.
user: {
uid: 1,
name: "johndoe",
fullname: "John Doe",
email: "johndoe#example.org",
pubkey: null
},
Change the the value of fullname to the username you want.
Reboot BeagleBone Black and go to 11.22.33.44:3000, and you shall see updated profile name on your Cloud9 IDE.
When starting Cloud9 from the command line (at least with the latest version) you can use the:
-a user:pass
where "user" is the user name it will permit and "pass" is the password for that user. It uses basic web authentication.
Other parameters for Cloud9 are:
-l [ip addresses to accept] Use 0.0.0.0 to accept all IP addresses.
-w path/to/project/to/edit
-p port on which to operate
As for the particular script/service that is used to start Cloud9 in which to tweak the startup parameters, I'm not sure. You might try this information for where to start looking:

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.
