Hello,

Thanks for sharing Network-NineP.

Just want to check if you have any sample examples using it?

Thanks again,

Hello,

Thanks for the samples. I am planning on writing a 9Pserver using Network-NineP. How do the clients (programmed in C) connect to it? Do they need to link or include these headers https://github.com/chaos/diod and make the calls listed in that library to read from the files provided by the 9PServer or do they just use the plain linux system read/write/open calls?

Thanks

l29ah commented 8 years ago

You can either make clients that talk 9P, or mount the filesystem in linux and use the usual syscalls. 9mount(1) is a nice suid program akin to pmount(1) that makes mounting 9P servers simpler.

Hello,

When I try to mount it, 

sudo mount -t 9p /tmp/h9pt /tmp/9pfs
mount: mount(2) failed: No such file or directory

smart_sudo lsmod | grep --colour=auto --ignore-case 9p
9p                     34512  0
9pnet_virtio            7261  0
virtio_ring             6787  1 9pnet_virtio
virtio                  5465  1 9pnet_virtio
9pnet                  59791  2 9p,9pnet_virtio

When I try with 9p:
/usr/lib/plan9/bin/9p read /tmp/h9pt
/usr/lib/plan9/bin/9p: mount: dial unix!/tmp/ns.joe.:0/: connect /tmp/ns.joe.:0/: Connection refused

Any suggestions on what I am missing, please?

Thanks

Anything interesting in dmesg?

9mount worked fine. I think the above mount command should be provided more options to work well.

Thanks

joe9 commented 8 years ago

@l29ah quick question, Instead of implementing the directory structure in the package, why not just use a library (FileSystem on MissingH.HVFS) for it? Just want to check if there was any reason for not taking that approach.

Thanks

joe9 commented 8 years ago

@l29ah sorry for bothering you about this. Could you please put the Data.NineP package also on github? It will be easier to raise issues, or pull requests.

l29ah commented 8 years ago

But it's there already: https://github.com/l29ah/9ph

l29ah commented 8 years ago

System.IO.HVFS is possible, but it will give a less usable/strict results as it doesn't provide a tree abstraction, i think.

@l29ah The hackage description still points to the googelcode webpage https://hackage.haskell.org/package/NineP-0.0.2.1. Thanks.
