#### 使用说明
|
|
|
|
|
|
|

|
|
|
|
**Terminal 1**: Create user/network/mount namespaces
|
|
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
|
(host)$ unshare --user --map-root-user --net --mount
|
|
|
|
|
|
(namespace)$ echo $$ > /tmp/pid
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
In this documentation, we use `(host)$` as the prompt of the host shell, `(namespace)$` as the prompt of the shell running in the namespaces.
|
|
|
|
|
|
|
|
|
|
|
|
If `unshare` fails, try the following commands (known to be needed on Debian, Arch, and old CentOS 7.X):
|
|
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
|
(host)$ sudo sh -c 'echo "user.max_user_namespaces=28633" >> /etc/sysctl.d/userns.conf'
|
|
|
|
|
|
(host)$ [ -f /proc/sys/kernel/unprivileged_userns_clone ] && sudo sh -c 'echo "kernel.unprivileged_userns_clone=1" >> /etc/sysctl.d/userns.conf'
|
|
|
|
|
|
(host)$ sudo sysctl --system
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
**Terminal 2**: Start slirp4netns
|
|
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
|
(host)$ slirp4netns --configure --mtu=65520 --disable-host-loopback $(cat /tmp/pid) tap0
|
|
|
|
|
|
starting slirp, MTU=65520
|
|
|
|
|
|
...
|
|
|
|
|
|
```
