ping: sendto: No route to host

[dgvinton]

Hello,

I'm running a-shell on an iPad Pro (11-inch) (3rd Generation).

First, thank you for developing a-shell. I love it!

Second, when I ping any device (except the iPad itself, 192.168.10.202) on the local subnet I receive "ping: sendto: No route to host" messages. External pings work. For example:

[~/Documents]$ ping -c2 192.168.10.202

Using Joe's Network Utility Pro, ping's to .204 receive replies.

Please advise.

Best regards,

I ran some tests, trying to ping a machine on the local network, without the -c 2 flag.

• on an iPad, running iOS 16: no issues, ping works as expected.
• on an iPhone, running iOS 18: ping starts by saying "sendto: No route to host" (about 4 times), then a popup window appears "Allow a-Shell to access devices on the local network?". Once I answer yes, ping works as expected.

It seems like a new protection was introduced in iOS 18. I would advise running ping with no flags until the popup window appears; after that it will be working nicely.

Thank you for the reply.When I first encountered the problem I was running ping without flags.  I must not have been paying attention for the pop-up?  The -c 2 was to keep my examples in the report brief.I’ll re-test on my iPhone and iPad..Don

There's also the possibility that the popup went up, and you said "No".
If that's the case, you will see the option in the Settings app, under Apps -> a-Shell -> "Local Network".

That was it.Thank you!
