Problem with Terminal Solved

Question

Hello,
I am on High Sierra 10.13.6. iMac 27" mid-2011.
I want to use Terminal to enter a "sudo" command.
The issue is that when I open Terminal, here's the info I get:
Last login: Tue Feb 16 22:51:47 on ttys000
You have new mail.
iphone-de-laurent:~ laurent$
It's not my iMac that appears, but my iPhone.
Why?
I don't know how to switch back to "iMac-de-Laurent:......." to launch my command.
Thank you for your help.

Hello,  Could you launch Applications -> Utilities -> Terminal and take the following two screenshots: this will help determine if any scripts are running at the startup of the Terminal utility: - the window obtained with the menu "Terminal -> Preferences ... -> General" - the window obtained with the menu "Terminal -> Preferences ... -> Profile -> Shell"  Just in case, here’s some help on: - Taking a screenshot on Mac -  How to insert an image into a discussion Note: Select the interesting part and not the entire screen; otherwise, the image will be too large and the texts will be unreadable.

Hello Ritchi What formulation? What you’re suggesting is unusual Should I include (->) and (.....) and the accents? Several attempts with no result "command not found" See you later  Best regards profiler31 (Toulouse)

Hello,  Thank you to Pyraah for translating my words and thus allowing profiler31 to take the two requested screenshots. These show that the Terminal is launched in a completely normal way: no script started at the Terminal launch.  I propose to make this modification:  In my case, I prefer to use bash, but if you prefer csh, ksh, tcsh, or zsh, simply replace bash with your choice.  Ritchi

I really don’t understand why my iPhone affects my iMac. My iPhone is registered in the same way as my MacBook Pro, and yet... On my MacBook Pro, the MacBook is correctly selected when I launch Terminal. It's all very confusing.  -- Best regards profiler31 (Toulouse)

Hello Can you type crontab -l in the Terminal window and share the screenshot here (and not on cijoint)? Ritchi

Hello,  I suspect something very simple... a name error for the Mac in question?  On your Mac, can you go to System Preferences, click on the "Sharing" button and check the name your Mac has in that section?  I can reproduce this kind of issue by naming my Mac "Francis's iPhone"...  Best regards.   PS: Hi Ritchi ;)

Ritchi, here is the Terminal window with your crontab -1 instruction  -- Best regards profiler31 (Toulouse)

Hello Francis
Yes! In sharing, it's iPhone-de-Laurent that is declared
Where does it come from ?????
I'll check in Sharing how to change it?
In any case, my question incidentally brings some answers; again, what are Emails doing in Terminal ???? and is it for all Mail addresses or just the main one?
"Strange, you said strange.....
Anyway, I'll go to "Sharing" and see..... and I'll keep you updated.
See you soon

Ritchi, here is with the proper wording  -- Best regards profiler31 (Toulouse)

profiler31 · Answer

Ritchi/Francis
The only automated actions are the "open/close computer" at fixed times and the FLUX software for brightness.
Otherwise, nothing else is done with full knowledge.
However, I can no longer find a way to modify the "iphone-de-Laurent" link in "Sharing," which seems to be causing chaos.

Help me

When you click on the "Edit" button near your computer's name in "Sharing," what do you get?   And what happens after changing it in the starting window?

profiler31 · Answer

I found out how to change my host address in Terminal
sudo scutil --set HostName (newHostName-withoutSpaces)
Password and Alt T and it's changed.
However, I haven't found how to change it in Sharing: I still have my iPhone address.
I'll do as you say
See you +

profiler31 · Answer

Done; but nothing

exchange

I have always "iphone-de-Laurent" afp or smb in File Sharing: enabled
It seemed to me that not long ago we had the possibility to start sharing with afp or smb from a window? Could it be related to the sharing settings from my wife's computer?

profiler31 · Answer

No changes! We'll leave it at that for tonight; the night brings counsel. Two questions remain unanswered:
- why is "mail" activated in Terminal; I haven't found a solution to exempt myself from it?
- why after the manipulations do I still have afp and sbm "iphone de Laurent.home" in the shares?

Tomorrow I will restart the sharing on my wife's computer and try to log in to my iMac with the current configuration. We'll see if the iPhone is not assimilated with the iMac?
I hope solutions will be found

In any case, thank you both for all this assistance; good night and see you tomorrow for sure

Just one thing tonight before I forget :), you should check if on your iPhone, in the settings, you have enabled "Personal Hotspot," and in the system preferences on the Mac, under Network, if the iPhone is designated as a possible way to connect to the internet...

profiler31 · Answer

In iPhone no tethering

Here are the answers...... unfortunately
Tomorrow I will restart the sharing on my wife's computer and try to connect with my iMac using the current configuration. We'll see if the iPhone is not recognized as iMac?

Hello,

I have an idea, try to find the relevant settings or preferences file by using the EasyFind utility, searching the contents of files that contain this preference or setting, and thus a search parameterized like this:

If EasyFind finds the file containing this term, right-click on the line to show it in Finder... probably a preferences file in .plist format
The file can then be deleted.

You can find EasyFind here:

https://www.devontechnologies.com/apps/freeware

or on the App Store.

profiler31 · Answer

Hello,
Launched EasyFind here is the result.....not convincing at all

I confirm that on my wife’s computer, the sharing works well with "Imac-de-Laurent" and that it is inactive! no access to my iMac
Moreover, from my iMac, I do have access to my wife's; Sharing her files.
So iPhone-de-Laurent not recognized but that doesn’t surprise me!

profiler31 · Answer

In principle, "Who can do more can do less"; I followed up with your selection; I'm waiting for the result.
I have thoroughly checked the settings on my iPhone; there is no mention/sharing of iMac anywhere.
The only connection between the two is during "sync" or "backup" with/on my iMac.

profiler31 · Answer

Here is the result

profiler31 · Answer

OK, I'm thinking on my side See you later

profiler31 · Answer

I've searched well... and found a flaw.
- when I'm in the current configuration (Ethernet)
I can access my iMac from my MacBook
I have access to the Asus
the Asus does not have access to my iMac
the MacBook has access to my iMac with some alerts but it works
- I switched to WIFI on my iMac and there I have afp and smb://iMac-de-Laurent-2.home
the network has "doubled" the address of my iMac and in this configuration I have access to both computers in both directions.
- I conclude that the problem comes from the MAC or IP address under Ethernet.
Remember; when I brought up the issue I had:
iPhone-de-Laurent in the Terminal
and iPhone-de-Laurent.local in "Sharing"
I changed the name to "iMac de Laurent" in the "Terminal" by a sudo action......
I changed the name to "iMac de Laurent.local" in "Sharing"
BUT without making any changes to the MAC or IP address.
It's like renaming my car from "DS4" to "Twingo" without modifying "the engine".
Armed with this observation, QUESTION
Having spotted the MAC and IP addresses of my iMac WHERE and HOW to remove the MAC and IP addresses of my iPhone to replace them with those of my iMac.
Because, there, there shouldn't be - I think - a problem anymore.
What do you think?
Your insight will be welcome
A +

The last screen shows my MacBook in Ethernet; it indicates an address afp:// or smb:// Mac-Book-Pro-1.home; when it switches from WiFi to Ethernet it changes the MAC and/or IP address.

Anonymous user · Answer

Hello,

the MAC addresses are different between WIFI and Ethernet. This is normal, and you can check it in the About This Mac / System Report / Network / Configuration menu...

What you could try is to put your Mac in WIFI only mode, with the Ethernet cable unplugged from the Mac, check in Sharing, the name of your computer, then do the opposite, connect the Ethernet and disable WIFI, check the name of your computer again...

Additionally, make sure that in WIFI mode, your iPhone is not acting as an internet hotspot... at some point, you may have allowed internet connection sharing on your iPhone, and this network may be saved on the Mac...

profiler31 · Answer

All the proposed manipulations confirm what you are writing and have been the subject of my screenshots.
I only used "Orange" as an internet access point on my MacBook during a trip, which I deleted, but this does not affect the functioning on my MacBook (see last screenshot).

So my question is indeed formulated in my last message:
"Having identified the MAC and IP addresses of my iMac, WHERE and HOW do I delete the MAC and IP addresses of my iPhone to replace them with those of my iMac?
Because, there, I don't think there will be a problem anymore."

It's your technical expertise that is speaking now that the diagnosis has been made, as personally, I don't know how to do it.

Thank you in advance
and have a good evening

:)))

You trust me too much ;-)

But I will think about it... in the meantime, if it hasn't been done already, uncheck the option to remember networks in System Preferences / Network... on each of your devices:

I will dig deeper on my side...

EDIT: and as much as possible, disable Bluetooth on your iPhone and Mac, at least for testing...

profiler31 · Answer

Hello,
Perseverance always pays off. After my diagnosis and a few hours of trial and error, I started from scratch and went back up the chain;
So the very beginning is the Livebox; I did a "reset" and checked/assigned the IP addresses of my devices.
I then went to "Network Configuration" and clicked "Automatic." And there were no more conflicts! In "System Preferences," "Sharing,"
1. I confirmed the firewall identity between the "Computer Name" and access via afp://...... and smb://.......
2. I took the opportunity to update "Users and Groups," and after that, I can access both my computers (MacBook Pro and Asus), and each of them can access "iMac" and "MacBook Pro" or "Asus."

Q.E.D.
In the meantime, a very big thank you to you and Ritchi for your assistance and support (technical and moral).

Have a great weekend, all the best, and see you soon on the line
