# slirp4netns
|
||
|
||
#### 介绍
|
||
slirp4netns provides user-mode networking ("slirp") for unprivileged network namespaces.
|
||
|
||
|
||
#### 安装教程
|
||
|
||
Install slirp4netns rpm package:
|
||
|
||
yum install slirp4netns
|
||
|
||
#### 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
|
||
...
|
||
```
