[Ryu-devel] Testing BGP in ryu

[Pynbiang Hadem]

Hi,

I want to run the RYU BGP
application(ryu/ryu/services/protocols/application.py) for a network with
three AS. Do i need to run 3 instances of the application, one instance for
each AS?. OR am i having a wrong idea about this?.

Pls advice. I am not able to proceed with the test.

Thanks
Hadem

Hi, Pynbiang.


Yes, you need to run at least 3 instances of the application for a
network with three AS.
If you want to run more BGP instances in an AS, you need to run more
instances of the application.


Thanks,
Fujimoto

Hi,

I prepared two instances of the RYU BGP app as below:
1) /home/mininet/BGP1/application1.py
2) /home/mininet/BGP2/application2.py

I also made the changes to the application1.py (correspondingly for
application2.py) as below:

CONF.register_opts([
cfg.IntOpt('bind-port', default=50001, help='rpc-port'),
cfg.StrOpt('bind-ip', default='0.0.0.1', help='rpc-bind-ip'),
cfg.StrOpt('bgp-config-file', default="/home/mininet/BGP1/bgpconfig1.py",
help='bgp-config-file')
])

I am also attaching herewith the modified *configuration files* taken
from ryu/ryu/services/protocols/bgp_sample_conf.py for application1.py
and application2.py respectively.

The problem is that i am not able to run the two applications simultaneously.

Kindly advice what else i am missing here.


Thanks

Hadem

Hi, Pynbiang


I guess it is the cause of the problem that the two applications use the
same port.
Unfortunately, the port which the application uses is no configurable,
so you cannot run the two applications simultaneously in a single host.

To run the applications, I suggest the following choices.

1. I recommend you to use Docker or VM(Virtual Box, KVM, ...).
You can run applications in each container or VM.

2. If you have installed mininet, you can run applications in each
virtual host("h1", "h2", ...) created by mininet.
It is because the namespace is separated by virtual hosts.
Please note that virtual switches such as "s1" is not in a
separated namespace,
so you have to run applications in virtual hosts.

Fujimoto

Hi, Pynbiang


FYI, you can run two Ryu BGP applications by the following steps:

1. Run mininet
$ sudo mn --switch ovsbr --topo single,2 --mac -x

2. Run applications in each host
h1> ryu-manager [application1.py] --bgp-app-config-file
[config_file_for_application1.py]
h2> ryu-manager [application2.py] --bgp-app-config-file
[config_file_for_application2.py]


Thanks,
Fujimoto

Hi,

I'm running the above BGP test applications on ryu 3.30 and am getting some
errors:

File "/usr/local/lib/python2.7/dist-packages/eventlet/greenio/base.py",
line 46, in socket_checkerr
raise socket.error(err, errno.errorcode[err])
error: [Errno 101] ENETUNREACH

I executed as below:

ryu-manager /home/mininet/BGP3/application1.py --config-file
/home/mininet/BGP3/ryu.conf


Do i need to run it on higher version of ryu?. Pls advice

Thanks

Hi, Pynbiang

I'm sorry for that I've overlooked your reply.

I think something may be wrong with your ryu.conf, especially about IP
address or port settings.
Please check your ryu.conf, or could you let me see your ryu.conf?

Thanks,

What could be the issue here?. i am using OpenvSwitch 2.7 & ryu 4.14

Thanks

Hi, Pynbiang
I'm sorry for that I've overlooked your reply.
I think something may be wrong with your ryu.conf, especially about IP
address or port settings.
Please check your ryu.conf, or could you let me see your ryu.conf?
Thanks,
Fujimoto
Hi Fujimoto,

Hi,
I'm running the above BGP test applications on ryu 3.30 and am getting
File "/usr/local/lib/python2.7/dist-packages/eventlet/greenio/base.py", line 46, in socket_checkerr
raise socket.error(err, errno.errorcode[err])
error: [Errno 101] ENETUNREACH
ryu-manager /home/mininet/BGP3/application1.py --config-file /home/mininet/BGP3/ryu.conf
Do i need to run it on higher version of ryu?. Pls advice
Thanks

Post by Pynbiang Hadem
Thanks Fujimoto for the insightful reply.
I will try to implement it accordingly.

Hi, Pynbiang
1. Run mininet
$ sudo mn --switch ovsbr --topo single,2 --mac -x
2. Run applications in each host
h1> ryu-manager [application1.py] --bgp-app-config-file
[config_file_for_application1.py]
h2> ryu-manager [application2.py] --bgp-app-config-file
[config_file_for_application2.py]
Thanks,
Fujimoto
Hi, Pynbiang
I guess it is the cause of the problem that the two applications use
the same port.
Unfortunately, the port which the application uses is no configurable,
so you cannot run the two applications simultaneously in a single host.
To run the applications, I suggest the following choices.
1. I recommend you to use Docker or VM(Virtual Box, KVM, ...).
You can run applications in each container or VM.
2. If you have installed mininet, you can run applications in each
virtual host("h1", "h2", ...) created by mininet.
It is because the namespace is separated by virtual hosts.
Please note that virtual switches such as "s1" is not in a
separated namespace,
so you have to run applications in virtual hosts.
Thanks,
Fujimoto
Hi,
1) /home/mininet/BGP1/application1.py
2) /home/mininet/BGP2/application2.py
I also made the changes to the application1.py (correspondingly for
CONF.register_opts([
cfg.IntOpt('bind-port', default=50001, help='rpc-port'),
cfg.StrOpt('bind-ip', default='0.0.0.1', help='rpc-bind-ip'),
cfg.StrOpt('bgp-config-file', default="/home/mininet/BGP1/bgpconfig1.py",
help='bgp-config-file')
])
I am also attaching herewith the modified *configuration files* taken from ryu/ryu/services/protocols/bgp_sample_conf.py for application1.py and application2.py respectively.
The problem is that i am not able to run the two applications simultaneously.
Kindly advice what else i am missing here.
Thanks

Hi, Pynbiang. Yes, you need to run at least 3 instances of the
application for a network with three AS. If you want to run more BGP
instances in an AS, you need to run more instances of the application.
Thanks, Fujimoto
Hi,
I want to run the RYU BGP application(ryu/ryu/services/protocols/application.py)
for a network with three AS. Do i need to run 3 instances of the
application, one instance for each AS?. OR am i having a wrong idea about
this?.
Pls advice. I am not able to proceed with the test.
Thanks

So, "ryu-manager" may not have authority to use well-known port 179,
which is used for BGP protocol.

Please run your command with "sudo", that is:

Hi, Fujimoto

Tried with as you suggested.
sudo ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py

However, the output is still the same.

what could be the issue?.

Thanks
Hadem

Hi, Pynbiang
Thank you for sending your log messages!
Error creating socket: [Errno 13] Permission denied
So, "ryu-manager" may not have authority to use well-known port 179,
which is used for BGP protocol.
sudo ryu-manager ryu/services/protocols/bgp/application.py --bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
Thanks,
Fujimoto

Hi Pynbiang,

Excuse me for jumping in.

It's just my guess, is IPv6 disabled on your machine?
Mininet does disable IPv6 automatically on its installation.

https://github.com/mininet/mininet/blob/aa8901268dbb04e11d466732a354b3533e0e138e/util/install.sh#L615-L639

Could you confirm the IPv6 settings (e.g., "/etc/sysctl.conf" and "/etc/default/grub")
on your machine?

Thanks,
Iwase

So, "ryu-manager" may not have authority to use well-known port 179,

HI Fujimoto,

Yes, i guess you are right. i have the following lines of code in
*/etc/sysctl.conf*

*# Mininet: disable IPv6*
*net.ipv6.conf.all.disable_ipv6 = 1*
*net.ipv6.conf.default.disable_ipv6 = 1*
*net.ipv6.conf.lo.disable_ipv6 = 1*

And the following code in */etc/default/grub*
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
GRUB_CMDLINE_LINUX=""

GRUB_SERIAL_COMMAND="serial --unit=0 --speed=9600 --stop=1"

Is there anything wrong with my settings?.

Thanks
Hadem

Hi Pynbiang,

Mininet does "disable IPv6" with some reason, I guess.
But on my environment, I can run Mininet with IPv6 enabled.

To revert "disable IPv6" settings;
1. Comment inserted line out from "/etc/sysctl.conf" and invoke "sysctl -p" to take effect.
---
# Mininet: disable IPv6
-net.ipv6.conf.all.disable_ipv6 = 1
-net.ipv6.conf.default.disable_ipv6 = 1
-net.ipv6.conf.lo.disable_ipv6 = 1
+#net.ipv6.conf.all.disable_ipv6 = 1
+#net.ipv6.conf.default.disable_ipv6 = 1
+#net.ipv6.conf.lo.disable_ipv6 = 1
---
2. Remove "ipv6.disable=1" from "GRUB_CMDLINE_LINUX_DEFAULT" in "/etc/default/grub"
and execute "sudo update-grub" command.
---
-GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
+GRUB_CMDLINE_LINUX_DEFAULT="text "
---
3. Reboot.

Then, confirm IPv6 addresses are assigned to interfaces on your machine.
e.g.)
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever


Thanks,
Iwase

HI Fujimoto,
Yes, i guess you are right. i have the following lines of code in */etc/sysctl.conf*
/
/
/# Mininet: disable IPv6/
/net.ipv6.conf.all.disable_ipv6 = 1/
/net.ipv6.conf.default.disable_ipv6 = 1/
/net.ipv6.conf.lo.disable_ipv6 = 1/
And the following code in */etc/default/grub*
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
GRUB_CMDLINE_LINUX=""
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=9600 --stop=1"
Is there anything wrong with my settings?.
Thanks
Hadem
Hi Pynbiang,
Excuse me for jumping in.
It's just my guess, is IPv6 disabled on your machine?
Mininet does disable IPv6 automatically on its installation.
https://github.com/mininet/mininet/blob/aa8901268dbb04e11d466732a354b3533e0e138e/util/install.sh#L615-L639

Could you confirm the IPv6 settings (e.g., "/etc/sysctl.conf" and "/etc/default/grub")
on your machine?
Thanks,
Iwase
Hi, Fujimoto
Tried with as you suggested.
sudo ryu-manager ryu/services/protocols/bgp/application.py --bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
However, the output is still the same.
what could be the issue?.
Thanks
Hadem
Hi, Pynbiang
Thank you for sending your log messages!
Error creating socket: [Errno 13] Permission denied
So, "ryu-manager" may not have authority to use well-known port 179,
which is used for BGP protocol.
sudo ryu-manager ryu/services/protocols/bgp/application.py --bgp-app-config-file

Hi Fujimoto,
*Pls ignore the last mail. I have corrected the command as below as pointed out by
you in one
of the other Forum blogs:*

Hi Pynbiang,
Mininet does "disable IPv6" with some reason, I guess.
But on my environment, I can run Mininet with IPv6 enabled.
To revert "disable IPv6" settings;
1. Comment inserted line out from "/etc/sysctl.conf" and invoke "sysctl -p" to take effect.
---
# Mininet: disable IPv6
-net.ipv6.conf.all.disable_ipv6 = 1
-net.ipv6.conf.default.disable_ipv6 = 1
-net.ipv6.conf.lo.disable_ipv6 = 1
+#net.ipv6.conf.all.disable_ipv6 = 1
+#net.ipv6.conf.default.disable_ipv6 = 1
+#net.ipv6.conf.lo.disable_ipv6 = 1
---
2. Remove "ipv6.disable=1" from "GRUB_CMDLINE_LINUX_DEFAULT" in "/etc/default/grub"
and execute "sudo update-grub" command.
---
-GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
+GRUB_CMDLINE_LINUX_DEFAULT="text "
---
3. Reboot.
Then, confirm IPv6 addresses are assigned to interfaces on your machine.
e.g.)
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
Thanks,
Iwase

HI Fujimoto,
Yes, i guess you are right. i have the following lines of code in */etc/sysctl.conf*
/
/
/# Mininet: disable IPv6/
/net.ipv6.conf.all.disable_ipv6 = 1/
/net.ipv6.conf.default.disable_ipv6 = 1/
/net.ipv6.conf.lo.disable_ipv6 = 1/
And the following code in */etc/default/grub*
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
GRUB_CMDLINE_LINUX=""
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=9600 --stop=1"
Is there anything wrong with my settings?.
Thanks
Hadem
Hi Pynbiang,
Excuse me for jumping in.
It's just my guess, is IPv6 disabled on your machine?
Mininet does disable IPv6 automatically on its installation.
https://github.com/mininet/mininet/blob/aa8901268dbb04e11d46
6732a354b3533e0e138e/util/install.sh#L615-L639
<https://github.com/mininet/mininet/blob/aa8901268dbb04e11d4
66732a354b3533e0e138e/util/install.sh#L615-L639>
Could you confirm the IPv6 settings (e.g., "/etc/sysctl.conf" and
"/etc/default/grub")
on your machine?
Thanks,
Iwase
Hi, Fujimoto
Tried with as you suggested.
sudo ryu-manager ryu/services/protocols/bgp/application.py --bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
However, the output is still the same.
what could be the issue?.
Thanks

Hi, Pynbiang
Thank you for sending your log messages!
Error creating socket: [Errno 13] Permission denied
So, "ryu-manager" may not have authority to use well-known port 179,
which is used for BGP protocol.

[Iwase Yusuke]

Hi Pynbiang,

Did you execute "sudo update-grub" command and then reboot?
The outputs of "ip a" command shows IPv6 is NOT enabled...

Thanks,
Iwase

Hi Pynbiang,
Mininet does "disable IPv6" with some reason, I guess.
But on my environment, I can run Mininet with IPv6 enabled.
To revert "disable IPv6" settings;
1. Comment inserted line out from "/etc/sysctl.conf" and invoke "sysctl -p" to take effect.
---
# Mininet: disable IPv6
-net.ipv6.conf.all.disable_ipv6 = 1
-net.ipv6.conf.default.disable_ipv6 = 1
-net.ipv6.conf.lo.disable_ipv6 = 1
+#net.ipv6.conf.all.disable_ipv6 = 1
+#net.ipv6.conf.default.disable_ipv6 = 1
+#net.ipv6.conf.lo.disable_ipv6 = 1
---
2. Remove "ipv6.disable=1" from "GRUB_CMDLINE_LINUX_DEFAULT" in "/etc/default/grub"
and execute "sudo update-grub" command.
---
-GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
+GRUB_CMDLINE_LINUX_DEFAULT="text "
---
3. Reboot.
Then, confirm IPv6 addresses are assigned to interfaces on your machine.
e.g.)
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 <http://127.0.0.1/8> scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
Thanks,
Iwase
HI Fujimoto,
Yes, i guess you are right. i have the following lines of code in */etc/sysctl.conf*
/
/
/# Mininet: disable IPv6/
/net.ipv6.conf.all.disable_ipv6 = 1/
/net.ipv6.conf.default.disable_ipv6 = 1/
/net.ipv6.conf.lo.disable_ipv6 = 1/
And the following code in */etc/default/grub*
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
GRUB_CMDLINE_LINUX=""
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=9600 --stop=1"
Is there anything wrong with my settings?.
Thanks
Hadem
Hi Pynbiang,
Excuse me for jumping in.
It's just my guess, is IPv6 disabled on your machine?
Mininet does disable IPv6 automatically on its installation.
https://github.com/mininet/mininet/blob/aa8901268dbb04e11d466732a354b3533e0e138e/util/install.sh#L615-L639

Could you confirm the IPv6 settings (e.g., "/etc/sysctl.conf" and "/etc/default/grub")
on your machine?
Thanks,
Iwase
Hi, Fujimoto
Tried with as you suggested.
sudo ryu-manager ryu/services/protocols/bgp/application.py --bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
However, the output is still the same.
what could be the issue?.
Thanks
Hadem
Hi, Pynbiang
Thank you for sending your log messages!
Error creating socket: [Errno 13] Permission denied
So, "ryu-manager" may not have authority to use well-known port 179,
which is used for BGP protocol.

Hi Pynbiang,
Did you execute "sudo update-grub" command and then reboot?
The outputs of "ip a" command shows IPv6 is NOT enabled...
Thanks,
Iwase

Hi Pynbiang,
Mininet does "disable IPv6" with some reason, I guess.
But on my environment, I can run Mininet with IPv6 enabled.
To revert "disable IPv6" settings;
1. Comment inserted line out from "/etc/sysctl.conf" and invoke
"sysctl -p" to take effect.
---
# Mininet: disable IPv6
-net.ipv6.conf.all.disable_ipv6 = 1
-net.ipv6.conf.default.disable_ipv6 = 1
-net.ipv6.conf.lo.disable_ipv6 = 1
+#net.ipv6.conf.all.disable_ipv6 = 1
+#net.ipv6.conf.default.disable_ipv6 = 1
+#net.ipv6.conf.lo.disable_ipv6 = 1
---
2. Remove "ipv6.disable=1" from "GRUB_CMDLINE_LINUX_DEFAULT" in "/etc/default/grub"
and execute "sudo update-grub" command.
---
-GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
+GRUB_CMDLINE_LINUX_DEFAULT="text "
---
3. Reboot.
Then, confirm IPv6 addresses are assigned to interfaces on your machine.
e.g.)
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 <http://127.0.0.1/8> scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
Thanks,
Iwase
HI Fujimoto,
Yes, i guess you are right. i have the following lines of code in
*/etc/sysctl.conf*
/
/
/# Mininet: disable IPv6/
/net.ipv6.conf.all.disable_ipv6 = 1/
/net.ipv6.conf.default.disable_ipv6 = 1/
/net.ipv6.conf.lo.disable_ipv6 = 1/
And the following code in */etc/default/grub*
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
GRUB_CMDLINE_LINUX=""
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=9600 --stop=1"
Is there anything wrong with my settings?.
Thanks

Hi Pynbiang,
Excuse me for jumping in.
It's just my guess, is IPv6 disabled on your machine?
Mininet does disable IPv6 automatically on its installation.
https://github.com/mininet/mininet/blob/aa8901268dbb04e11d46

Could you confirm the IPv6 settings (e.g.,
"/etc/sysctl.conf" and "/etc/default/grub")
on your machine?
Thanks,
Iwase
Hi, Fujimoto
Tried with as you suggested.
sudo ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
However, the output is still the same.
what could be the issue?.
Thanks

Hi, Pynbiang
Thank you for sending your log messages!

[Iwase Yusuke]

Hi,

Sorry for the delay.

I guess these message are just warning on Python 2.

On Python 2, the "implicit relative import" is allowed, so interpreter try to find
modules from current path and will fail to find "os" module from "ryu.services
.protocols.bgp.bgpspeaker.application".
OTOH, on Python 3, the implicit relative import is NOT allowed, then no warnings
should be shown.

You can ignore these messages, but I will send a patch to suppress them.

Thanks,
Iwase

Hi Pynbiang,
Did you execute "sudo update-grub" command and then reboot?
The outputs of "ip a" command shows IPv6 is NOT enabled...
Thanks,

Hi Pynbiang,
Mininet does "disable IPv6" with some reason, I guess.
But on my environment, I can run Mininet with IPv6 enabled.
To revert "disable IPv6" settings;
1. Comment inserted line out from "/etc/sysctl.conf" and invoke "sysctl -p" to take effect.
---
# Mininet: disable IPv6
-net.ipv6.conf.all.disable_ipv6 = 1
-net.ipv6.conf.default.disable_ipv6 = 1
-net.ipv6.conf.lo.disable_ipv6 = 1
+#net.ipv6.conf.all.disable_ipv6 = 1
+#net.ipv6.conf.default.disable_ipv6 = 1
+#net.ipv6.conf.lo.disable_ipv6 = 1
---
2. Remove "ipv6.disable=1" from "GRUB_CMDLINE_LINUX_DEFAULT" in "/etc/default/grub"
and execute "sudo update-grub" command.
---
-GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
+GRUB_CMDLINE_LINUX_DEFAULT="text "
---
3. Reboot.
Then, confirm IPv6 addresses are assigned to interfaces on your machine.
e.g.)
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 <http://127.0.0.1/8> <http://127.0.0.1/8> scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
Thanks,
Iwase
HI Fujimoto,
Yes, i guess you are right. i have the following lines of code in */etc/sysctl.conf*
/
/
/# Mininet: disable IPv6/
/net.ipv6.conf.all.disable_ipv6 = 1/
/net.ipv6.conf.default.disable_ipv6 = 1/
/net.ipv6.conf.lo.disable_ipv6 = 1/
And the following code in */etc/default/grub*
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
GRUB_CMDLINE_LINUX=""
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=9600 --stop=1"
Is there anything wrong with my settings?.
Thanks
Hadem
Hi Pynbiang,
Excuse me for jumping in.
It's just my guess, is IPv6 disabled on your machine?
Mininet does disable IPv6 automatically on its installation.

Could you confirm the IPv6 settings (e.g., "/etc/sysctl.conf" and
"/etc/default/grub")
on your machine?
Thanks,
Iwase
Hi, Fujimoto
Tried with as you suggested.
sudo ryu-manager ryu/services/protocols/bgp/application.py
--bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
However, the output is still the same.
what could be the issue?.
Thanks

Hi, Pynbiang
Thank you for sending your log messages!
Error creating socket: [Errno 13] Permission denied
So, "ryu-manager" may not have authority to use well-known port 179,
which is used for BGP protocol.
sudo ryu-manager ryu/services/protocols/bgp/application.py

Thanks Iwase

Post by Iwase Yusuke
Hi,
Sorry for the delay.
I guess these message are just warning on Python 2.
On Python 2, the "implicit relative import" is allowed, so interpreter try to find
modules from current path and will fail to find "os" module from "ryu.services
.protocols.bgp.bgpspeaker.application".
OTOH, on Python 3, the implicit relative import is NOT allowed, then no warnings
should be shown.
You can ignore these messages, but I will send a patch to suppress them.
Thanks,
Iwase

Hi Pynbiang,
Did you execute "sudo update-grub" command and then reboot?
The outputs of "ip a" command shows IPv6 is NOT enabled...

Hi Pynbiang,
Mininet does "disable IPv6" with some reason, I guess.
But on my environment, I can run Mininet with IPv6 enabled.
To revert "disable IPv6" settings;
1. Comment inserted line out from "/etc/sysctl.conf" and
invoke "sysctl -p" to take effect.
---
# Mininet: disable IPv6
-net.ipv6.conf.all.disable_ipv6 = 1
-net.ipv6.conf.default.disable_ipv6 = 1
-net.ipv6.conf.lo.disable_ipv6 = 1
+#net.ipv6.conf.all.disable_ipv6 = 1
+#net.ipv6.conf.default.disable_ipv6 = 1
+#net.ipv6.conf.lo.disable_ipv6 = 1
---
2. Remove "ipv6.disable=1" from "GRUB_CMDLINE_LINUX_DEFAULT"
in "/etc/default/grub"
and execute "sudo update-grub" command.
---
-GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
+GRUB_CMDLINE_LINUX_DEFAULT="text "
---
3. Reboot.
Then, confirm IPv6 addresses are assigned to interfaces on your machine.
e.g.)
$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state
UNKNOWN group default qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 <http://127.0.0.1/8> <
http://127.0.0.1/8> scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
Thanks,
Iwase
HI Fujimoto,
Yes, i guess you are right. i have the following lines
of code in */etc/sysctl.conf*
/
/
/# Mininet: disable IPv6/
/net.ipv6.conf.all.disable_ipv6 = 1/
/net.ipv6.conf.default.disable_ipv6 = 1/
/net.ipv6.conf.lo.disable_ipv6 = 1/
And the following code in */etc/default/grub*
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 text "
GRUB_CMDLINE_LINUX=""
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=9600 --stop=1"
Is there anything wrong with my settings?.
Thanks

Hi Pynbiang,
Excuse me for jumping in.
It's just my guess, is IPv6 disabled on your machine?
Mininet does disable IPv6 automatically on its installation.

Could you confirm the IPv6 settings (e.g., "/etc/sysctl.conf" and
"/etc/default/grub")
on your machine?
Thanks,
Iwase
Hi, Fujimoto
Tried with as you suggested.
sudo ryu-manager ryu/services/protocols/bgp/app
lication.py
--bgp-app-config-file
ryu/services/protocols/bgp/bgp_sample_conf.py
However, the output is still the same.
what could be the issue?.
Thanks

Hi, Pynbiang
Thank you for sending your log messages!
