If Nothing Appears When You Type in Your Password at Command Line Interface (Terminal, cmd.exe, console, etc) Prompt:

  • This is normal.  Your password is masked on the screen so others watching can't guess it.
  • Letters and numbers in passwords may not appear here as you type them at the password prompt.
  • Type your password anyway.
  • The press Enter/Return.
If You Forgot Your Password for Oracle2.cci.drexel.edu (or for sqlplus on linux.cci.drexel.edu):

If you see "Your connection not fully secure" or "Warning: Potential Security Risk Ahead"?

  • As long as you see this message when on https://linux.cci.drexel.edu or https://linux.cci.drexel.edu/signup/index.pl , then it's okay to do one of the following:
  • Firefox: Click "Advanced" > "Accept the Risk and Continue." We host these websites. They are completely safe.
  • Chrome: "Advanced" > "Proceed to... (unsafe)". We host these websites. They are completely safe.
What is ike or @ike or user@ike or your-user-id@ike for?

  • See https://linux.cci.drexel.edu/docs/
  • @ike is used to login to sqlplus on linux.cci.drexel.edu. 
  • Same userid as your Drexel uesrid, but follow it with @ike instead (example: abc123@ike).
  • You'll see more on this at the above link. You'll need to click the PuTTY link, or Windows 10/11 Command Line or Mac OS links at the above link look at later steps in the instructions for more on the @ike user.

For connecting to oracle2.cci.drexel.edu via locally installed GUI, but not sqlplus on linux.cci.drexel.edu:

  • Use oracle2.cci.drexel.edu not oracle.cci.drexel.edu as the hostname
  • Most SQL GUIs don't use a hostname. Your username in SQLDeveloper is userid (without @ike).  E.g.: abc123

If you get the error "Your Drexel username and/or password is not correct":

  • ...after filling out & submitting the Oracle SQL on linux.cci.drexel.edu form, then you need to change your DrexelOne password FIRST.
  • Then come back to the Oracle SQl on linux.cci.drexel.edu form at
    https://linux.cci.drexel.edu/signup/
    to get a new password or change your password.
  • Your Drexel password is NOT the same as your Oracle2.cci.drexel.edu or linux.cci.drexel.edu password.
  • Your Drexel password is what you use for Bb Learn, Zoom, Office365, and other Drexel websites.
    Changing it will change that password for all of these other websites as well.
  • To change your DrexelOne password:
    Visit https://accounts.drexel.edu, and click "Forgot Password?"
    Or go directly to https://passwordreset.microsoftonline.com/

If you see "ORA-01017: Invalid Username/Password" after trying to login to SQLPLUS?

  • Make sure the SQLPLUS (or sqlplus) password matches your Oracle SQL on linux.cci.drexel.edu password.
  • Make sure the SQLPLUS (or sqlplus) password ONLY contains alphanumeric characters (a-z A-Z 0-9).
  • If it doesn't, or you still have issues, change your Oracle SQL on linux.cci.drexel.edu password at:
    https://linux.cci.drexel.edu/signup/
  • Sometimes, SQLPLUS does not like characters Oracle SQL on linux.cci.drexel.edu is okay with, and vice versa, or something gets out of sync between the 2 passwords. Changing the password 9 times out of 10 resolves this issue.
  • Changing your Oracle SQL on linux.cci.drexel.edu password is just like setting it for the 1st time.
  • Do not include in your new Oracle SQL on linux.cci.drexel.edu password ANY special or extended characters or punctuation, so do not include ! @ # $ % ^ & * ( ) ; , . [ ] { } \ | ` ~ ; : ' " < > / ? etc.

Fix SSH Hostkey error?

  • A while back now, linux.cci.drexel.edu was rebuilt and a new server was deployed. If you previously had an account on the old server, you could get error when connecting to the current server that the remote host identification has changed.  This can be ignored and the new fingerprint/id can for the current linux.cci.drexel.edu server can be saved

  • An example of the change in remote host identification error is shown below.

    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

    It is also possible that a host key has just been changed.

    The fingerprint for the RSA key sent by the remote host is
    SHA256…………………………………………………4

  • See Fix SSH host key error for Oracle SQL on linux.cci.drexel.edu

Customized ssh Commands/Hashes for Mac Users? Not Anymore. Probably.

Since linux.cci.drexel.edu was rebuilt with the latest CentOS and packages...

Mac users should no longer need to use the customized commands/hashes they had to use on the old server.  They should be able to ssh directly to the server now.

But just in case it ever comes up again.

SSH error - macOS X High Sierra users

  • To use the SSH client in the Mac terminal, type in the following. Replace USERID with your userid:
  • ssh -c 3des-cbc USERID@linux.cci.drexel.edu

SSH error - macOS X Mojave users:

  • To use the SSH client in the Mac terminal, type in the following. Replace USERID with your userid:
  • ssh -c 3des-cbc -oKexAlgorithms=+diffie-hellman-group1-sha1 USERID@linux.cci.drexel.edu

SSH error - macOS X Catalina users:

  • Mojave method above may also work.
  • To use the SSH client in the Mac terminal, type in the following. Replace USERID with your userid:
  • ssh -c 3des-cbc -oKexAlgorithms=+diffie-hellman-group1-sha1 USERID@linux.cci.drexel.edu
Incorrect Password or Still Have Password Authentication or Other Issues?

Cannot Delete Tables or Database? Primary Keys or Other Errors Doing so?

  • Please contact ihelp@drexel.edu  and we will help as soon as possible or direct you to your CA/Instructor.

Locked Tables

  • If your connection has been disrupted or other issues, unlocking automatically happens after 1-2 hours. Just log out of all sessions and wait for 1-2 hours and try again.

The Oracle.com website wants a username or email and password to download stuff like the local sqlplus client. What do I do?

  • The Oracle website login, username, email you use, and password are all separate from Drexel and from your Oracle SQL on linux.cci.drexel.edu account and from your Drexel password.
  • So just go ahead and register for and create an Oracle account, but ONLY IF YOU NEED TO DOWNLOAD FILES FROM ORACLE.
  • Oracle just wants everyone to make an account in order to download stuff.
  • NO DOWNLOAD OR INSTALL OF ORACLE is needed for Drexel CCI classes. Any assignment you see like this is almost always marked "Optional" in Bb Learn.
  • You might want to try and use SQL Developer, and that may be required, though.

SQL Developer Instructions

If you want to connect to CCI Oracle from SQL Developer

Refer to the following document Connecting to CCI Linux Oracle SQL Developer and Troubleshooting It

NOTE:

  • If you can login via a Terminal or Command prompt window using the ssh command to linux.cci.drexel.edu...
  • and login to sqlplus via a Terminal or Command prompt window as well,
  • then there isn't an account issue. 
  • Look at the above SQL Developer word document, 
  • and recheck/redo your configuration/set-up.
