Hi Fujimoto,

I am using Ubuntu 16 in Oracle VM. The machine is HP desktop using Win 7 64
bit. I wish this information is useful for you.

Meanwhile, I am the owner of this machine. I am the admin.

Thanks.

HI,

Hmm, I don't  know about your environment, so I can't give you a 
specific solution...

Please ask to the owner of your machine.

Thanks,
Fujimoto

Hi Fujimoto,

I tried to create "var/log/ryu" directory but I got a new error.

mkdir: cannot create directory "/var/log/ryu/": Permission denied.

Does it mean I don't have the permission to do it? I am the admin of

Hi,

The error message says that Ryu is trying to output the log into
"var/log/ryu/ryu.log", but
"var/log/ryu/" directory is missing.

By default, Ryu does not output the log into such place (does not
output log file).

https://github.com/osrg/ryu/blob/e1e85052f5563f120b1e62fd9282946be6154f5b/ryu/log.py#L40-L41



Did you specify "--log-dir" or "--log-file" option to ryu-manager?
Or creating "var/log/ryu/" directory should solve this problem, I
guess.

Thanks,
Fujimoto

Hi Fujimoto,

Thanks for help. I didn't specify any thing for ryu-manager. I just
installed by typing "pip install ryu" and install some dependencies.

I tried to create "var/log/ryu" directory but I got a new error.

mkdir: cannot create directory "/var/log/ryu/": Permission denied.

Does it mean I don't have the permission to do it? I am the admin of this
OS.

Thanks.

Re: [Ryu-devel] IOError: [Errno 2] No such file or directory: '/var/log/ryu/ryu.log

[Fujimoto Satoshi]

Hi,

The error message says that Ryu is trying to output the log into 
"var/log/ryu/ryu.log", but

"var/log/ryu/" directory is missing.

By default, Ryu does not output the log into such place (does not output 
log file).

https://github.com/osrg/ryu/blob/e1e85052f5563f120b1e62fd9282946be6154f5b/ryu/log.py#L40-L41

Did you specify "--log-dir" or "--log-file" option to ryu-manager?
Or creating "var/log/ryu/" directory should solve this problem, I guess.

Thanks,
Fujimoto
