实测日期：2026-11-06 UTC 环境：Debian GNU/Linux 13 (trixie), amd64, 云端容器，普通用户 agent Ubuntu 26.04 未实测：无 docker/podman；unshare -Ur 被环境拒绝。 ss/ip/ping 使用 Debian trixie 官方 .deb 解包后本地运行；未安装到系统。 HTTP：Python http.server.HTTPServer，自建响应 hello from local service；分别绑定 127.0.0.1 和 0.0.0.0；实验后关闭。 磁盘目录：手工创建 source/logs/cache，分别写入 1/2/8 MiB 文件；du 是实际磁盘占用，目录开销使数值略大。 free 是容器所见的系统快照，不代表容器配额；未制造内存或磁盘耗尽。 ps/TERM 只用于自己新建的 sleep 进程；没有实测 KILL、Ubuntu 安装及外部网络访问。 以下保留命令和输出，仅移除行尾空白；工具绝对路径表示本地解包位置。 $ /work/.case/runs/e0df73a8abd5/evidence/tools/usr/bin/ss -tlnp sport = :8080 State Recv-Q Send-Q Local Address:Port Peer Address:PortProcess LISTEN 0 5 127.0.0.1:8080 0.0.0.0:* users:(("python3",pid=48321,fd=3)) $ curl --noproxy '*' --max-time 3 -sS http://127.0.0.1:8080/ hello from local service $ /work/.case/runs/e0df73a8abd5/evidence/tools/usr/bin/ss -tlnp sport = :8080 State Recv-Q Send-Q Local Address:Port Peer Address:PortProcess LISTEN 0 5 0.0.0.0:8080 0.0.0.0:* users:(("python3",pid=48321,fd=3)) $ curl --noproxy '*' --max-time 3 -sS http://127.0.0.1:8080/ hello from local service $ /work/.case/runs/e0df73a8abd5/evidence/tools/usr/sbin/ip a 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 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 proto kernel_lo valid_lft forever preferred_lft forever 2: eth0@if720: mtu 1500 qdisc noqueue state UP group default link/ether 7e:52:e5:82:15:63 brd ff:ff:ff:ff:ff:ff link-netnsid 0 inet 172.20.0.5/16 brd 172.20.255.255 scope global eth0 valid_lft forever preferred_lft forever 3: tun0: mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 500 link/none inet 198.18.0.1/30 brd 198.18.0.3 scope global tun0 valid_lft forever preferred_lft forever inet6 fe80::9ab1:d37:dc9d:209e/64 scope link stable-privacy proto kernel_ll valid_lft forever preferred_lft forever $ /work/.case/runs/e0df73a8abd5/evidence/tools/usr/bin/ping -c 2 127.0.0.1 PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data. 64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.023 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.033 ms --- 127.0.0.1 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1025ms rtt min/avg/max/mdev = 0.023/0.028/0.033/0.005 ms $ df -h .
