Title:
When Ubuntu16.04.1 is in the virtualbox with NAT adapter, the network
will have errors about "Connection reset by peer"
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
By means of vagrant for using the ubuntu/xenial64 box, or under the
virtualbox 5.1.6/5.1.8, installing ubuntu-16.04.1-server-amd64.iso (default
installation + openssh server), ubuntu-16.04.1-desktop-amd64.iso (default
installation), designate the Adapter1 of Guest OS as NAT type.
In this case, some commands are executed with a "Connection reset by peer"
error, such as apt-key or docker pull.
==== The current test results ====
If the network is not NAT but NAT Network or Host Only, it will not go wrong.
If the virtual machine is not virtualbox, it will not go wrong.
Keeping other unchanged and just replacing centos with Ubuntu, it will not go
wrong.
Under different wifi environment, the test results remain unchanged.
Upgrade all ubuntu to the latest version by using sudo apt upgrade, the test
results are unchanged.
Maybe the combination of virtualbox + NAT + ubuntu1604 is the reason
and this error is very convert. Other network functions are available,
may have errors only in a specific command.
==== Repeating Steps ====
1. Run "vagrant init ubuntu/xenial64" in an empty directory
2. vagrant up
3. vagrant ssh
4. Run "sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:11371
--recv-keys 58118E89F3A912897C070ADBF76221572C52609D" in Guest OS.
The output is as follows :
Executing: /tmp/tmp.LO7eukZqdi/gpg.1.sh --keyserver
hkp://ha.pool.sks-keyservers.net:11371
--recv-keys

gpg: key 2C52609D: no valid user IDs
gpg: this may be caused by a missing self-signature
gpg: Total number processed: 1
gpg: w/o user IDs: 1
There is an error message during this "? : [fd 4]: read error:
Connection reset by peer"
==== Another error scene ====
I created a docker registry (called S) on the virtual machine of IDC, and
when I ran "docker pull xxx" from another ubuntu Guest OS (called C)
(virtualbox + NAT), you can see something from /var/log/syslog in C as follows:
Nov 3 12:59:00 ubuntu-xenial dockerd[2167]:
time="2016-11-03T12:59:00.506141276Z" level=error msg="Error trying v2
registry: read tcp 10.0.2.15:33580->10.99.169.227:5000: read: connection reset
by peer"
Nov 3 12:59:00 ubuntu-xenial dockerd[2167]:
time="2016-11-03T12:59:00.506732903Z" level=error msg="Attempting next endpoint
for pull after error: read tcp 10.0.2.15:33580->10.99.169.227:5000: read:
connection reset by peer”
The 10.99.169.227 is the ip of S.
S is also Ubuntu 16.04.1 LTS, but which is not running under the virtualbox.
Run the above repeating steps 4 in S will not appear "Connection reset by peer"
error.
==== Script which can be executed on other system ====
Attachment is a test script, which is copied from output /tmp/tmp.LO7eukZqdi
directory of the above repeating step 4. You can perform a test on any system
by following these steps:
1. tar -xf gpgtest.tar
2. cd gpgtest
3. ./gpg.1.sh --keyserver hkp://ha.pool.sks-keyservers.net:11371 --recv-keys
58118E89F3A912897C070ADBF76221572C52609D
In the environment of virtualbox + NAT + ubuntu, output will be like this:
gpg: WARNING: unsafe permissions on homedir `.'
gpg: requesting key 2C52609D from hkp server ha.pool.sks-keyservers.net
?: [fd 4]: read error: Connection reset by peer
gpgkeys: key 58118E89F3A912897C070ADBF76221572C52609D partially retrieved
(probably corrupt)
gpg: no valid OpenPGP data found.
gpg: key 2C52609D: no valid user IDs
gpg: this may be caused by a missing self-signature
gpg: Total number processed: 1
gpg: w/o user IDs: 1
You can see the output of "?: [Fd 4]: read error: Connection reset by
peer".
Under the vagrant + virtualbox + centos/7 box + NAT, the script output is
like this:
gpg: 警告：用户目录‘.’权限不安全
gpg: 下载密钥‘2C52609D’，从 hkp 服务器 ha.pool.sks-keyservers.net
gpg: 密钥 2C52609D：“Docker Release Tool (releasedocker) <doc...@docker.com>”未改变
gpg: 合计被处理的数量：1
gpg: 未改变：1
