Question or issue on macOS:
When using route with the -ifscope modifier, I get the following error: $ sudo route delete -ifscope utun0 -net 0.0.0.0 route: writing to routing socket: not in table delete net 0.0.0.0: not in table What am I doing wrong? What's the correct syntax of the route command in order to delete the default route? If you are intent on using route the man page for route will show you it's the same as most BSD route commands. You may need ip6config (and man page) as well if you care about IPv6 routing. The 'mac' way is to set it from the System Preference pane under network and is preferred over using unix commands since it honors location changes. The use field provides a count of the number of packets sent using that route. Expire is a timeout - a period in which the host doesn't respond to that route. MAC Address and Hardware Devices. The HEX address that you're seeing for the 10.1.0.10.1/32 network (bc:67:1c:40:3:f6) is a MAC.
- I need to retrieve the default gateway on a Mac machine. I know that in Linux route -n will give an output from which I can easily retrieve this information. However this is not working in Mac OSX(Snow Leopard). I also tried netstat -nr grep 'default', but I was hoping for a cleaner output like that produced by route -n in Linux/Unix.

I need to retrieve the default gateway on a Mac machine. I know that in Linux route -n will give an output from which I can easily retrieve this information. However this is not working in Mac OSX(Snow Leopard).
I also tried netstat -nr grep ‘default’, but I was hoping for a cleaner output like that produced by route -n in Linux/Unix. netstat -nr lists all the interfaces and the default gateway for them.
Any kind of suggestion or a hint in the right direction will be appreciated.
How to solve this problem?
Solution no. 1:
You can try with:
It is not the same as GNU/Linux’s route -n (or even ip route show) but is useful for checking the default route information.
Also, you can check the route that packages will take to a particular host. E.g.
The output would be similar to:
IMHO netstat -nr is what you need. Even MacOSX’s Network utility app(*) uses the output of netstat to show routing information.
I hope this helps 🙂
(*) You can start Network utility with open /Applications/Utilities/Network Utility.app
Solution no. 2:
For getting the list of ip addresses associated, you can use netstat command
This gives a long list of ip addresses and it is not easy to find the required field. The sample result is as following:
The ip address of gateway is in the first line; one with default at its first column.
To display only the selected lines of result, we can use grep command along with netstat
This command filters and displays those lines of result having default. In this case, you can see result like following:
If you are interested in finding only the ip address of gateway and nothing else you can further filter the result using awk. The awk command matches pattern in the input result and displays the output. This can be useful when you are using your result directly in some program or batch job.
The awk command tells to match and print the second column of the result in the text. The final result thus looks like this:
In this case, netstat displays all result, grep only selects the line with ‘default’ in it, and awk further matches the pattern to display the second column in the text.
You can similarly use route -n get default command to get the required result. The full command is
These commands work well in linux as well as unix systems and MAC OS.
Solution no. 3:

The grep utility is not needed. Awk can do it all:
Note that if you have something like Parallels (or a VPN, or both) running, you may see two or more default routing entries – it will be true if you use the ‘grep’ suggestion above, too.
and
To set a variable (_default) for further use (assuming only one entry for ‘default’) …..
In the case of multiple default routes use:
These examples tested in Mavericks Terminal.app and are specific to OSX only. For example, other *nix versions frequently use ‘eth’ for ethernet/wireless connections, not ‘en’.
This is also only tested with ksh. Other shells may need a slightly different syntax.
Solution no. 4:
I would use something along these lines…
Solution no. 5:
Using System Preferences:
Step 1: Click the Apple icon (at the top left of the screen) and select System Preferences.
Mac Os Mojave
Step 2: Click Network.
Step 3: Select your network connection and then click Advanced.
Step 4: Select the TCP/IP tab and find your gateway IP address listed next to Router.
Hope this helps!

Been a while since I've been around. Place still looks good.
I'm having an issue that even Apple's upper-level support guys can't seem to help with.
Basically, I built a Windows box for a business to replace their server. This server runs their billing sotware and beyond that, is nothing more than file storage. It's a printing company, and they house their graphics files and other stuff on it, with one drive that's shared out to 4 systems - 2 2016 iMacs and 2 Windows 10 systems. Neither of the Windows systems are having any trouble accessing their data at all. Zero issues.
However, on the Mac side of things, it's driving me insane. They use Adobe Illustrator and InDesign on both of them, as well as Office 2013. During the course of the day, they'll be going along fine, saving work to the server, then BAM, out of nowhere, they can't save to the server on a Mac UNTIL IT'S RESTARTED. Once the offending iMac is restarted, it'll normally be business as usual for a while until it does it again.
Some of the errors from Adobe products include:
The file is damaged and could not be repaired
The file cannot be saved. You do not have access.
So, when this happens, I've told them to save the file locally to their machine and copy it to the server. (SIDE NOTE: Adobe has repeadtedly told me that they don't support saving files over a local network. I've told them, but there's that whole not being able to get a horse to drink after being shown their water thing...)
However, what we've discovered is that when they copy the file to the server, it doesn't actually copy! I've NEVER seen this before. In fact, I spent avout 4 hours at the business last week because I wanted to see this actually happen. It did. They copied a file from the Mac to the server, it flashed a progress bar real fast, and never gave an error. But it didn't copy.
I've checked permissions until I'm blue in the face, and cannot figure out what the deal is. So, I'm hoping one of you Mac Geniuses can show me the light.
Thanks in advance!
