Oracle SQL -- linux.cci.drexel.edu (f.k.a. linux.ischool.drexel.edu)

linux.cci.drexel.edu was rebuilt and the new server was deployed. You could get error that the remote host identification has changed. This can be ignored and the new fingerprint/id can be saved.
1. 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

2. See Fix SSH host key error for Oracle SQL on linux.cci.drexel.edu.
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.
The new server hostname is “linux.cci.drexel.edu”. It is preferred to use that host name going forward.
However the old hostnames (linux.ischool.drexel.edu & linux.cis.drexel.edu) have been converted to CNAMES, and they usually still work.

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

...after filling out & submitting the Linux/Oracle/Java/iSchool form, then you need to change your DrexelOne password FIRST.
Then come back to the Linux/Oracle/Java/iSchool form password to get a new password or change your password.
Your DrexelOne 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.
Make sure the new DrexelOne password ONLY contains alphanumeric characters (a-z A-Z 0-9).
- Do not include in your new DrexelOne password ANY special or extended characters or punctuation, so do not include ! @ # $ % ^ & * ( ) ; , . [ ] { } \ | ` ~ ; : ' " < > / ? etc.
To change your DrexelOne password:
- Visit https://account.drexel.edu, and click "Forgot Password?"
  - Or go directly to https://passwordreset.microsoftonline.com/
If own a Drexel-managed or -owned machine, particularly a Mac, please contact ihelp@drexel.edu first, as changing your password here will change your password on your Drexel-managed or -owned machine, and that might be better done on-campus, and perhaps not done at all on a Mac, but we'll assist regardless.
- Drexel students working on their personal computers do not need to contact ihelp first.

The Oracle website wants a username or email and password to download stuff. What do I do?

The Oracle website login, username, email you use, and password are all separate from Drexel and from linux.cci.drexel.edu.
So just go ahead and register for and create an Oracle account IF YOU NEED TO DOWNLOAD FILES FROM ORACLE.
Oracle just wants everyone to make an account in order to download stuff.
The Oracle account you create is completely separate from the CCI linux.cci.drexel.edu website and Drexel Connect.
