需要满足的要求
- 必须可以访问互联网
- 必须配置有效的 DNS(IP 名称服务器)
- 需要将.zip或解压的文件传输到本地闪存上的一个交换机
- 交换机系统管理员角色用户
- 不得配置“system-cli disable”
从 OS10 交换机运行脚本的步骤
-
配置名称服务器
OS10(config)# ip name-server <dnsserverip>
-
确认可以 ping DNS 名称
OS10# ping debian.org PING debian.org (130.89.148.77) 56(84) bytes of data. 64 bytes from klecker-misc.debian.org (130.89.148.77): icmp_seq=1 ttl=45 time=123 ms 64 bytes from klecker-misc.debian.org (130.89.148.77): icmp_seq=2 ttl=45 time=123 ms ^C --- debian.org ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms
-
将文件复制到本地闪存
OS10# copy scp://root@<fileserverip>/cert_upgrade_script-3.zip home://cert_upgrade_script-3.zip password: OS10# dir home Directory contents for folder: home Date (modified) Size (bytes) Name --------------------- ------------ ------------------------------------------ 2021-05-18T00:28:45Z 8426 cert_upgrade_script-3.zip
-
移至 shell 提示符。安装“unzip”,然后安装“except”(如果文件未解压)。
leaf-2# system "sudo -i” We trust you have received the usual lecture from the local System Administrator.

解压和 chmod 以将文件更改为可执行文件
root@OS10:/home/admin# unzip cert_upgrade_script-3.zip Archive: cert_upgrade_script-3.zip inflating: cert_upgrade_script/cert.py inflating: cert_upgrade_script/cert.sh inflating: cert_upgrade_script/hosts.txt inflating: cert_upgrade_script/newdelldefault.crt inflating: cert_upgrade_script/README.md root@OS10:/home/admin# cd cert_upgrade_script root@OS10:/home/admin/cert_upgrade_script# ls -l total 31 -rw-r--r-- 1 root root 5019 Mar 25 14:52 README.md -rw-r--r-- 1 root root 9464 Apr 12 15:02 cert.py -rw-r--r-- 1 root root 11793 Apr 12 15:02 cert.sh -rw-r--r-- 1 root root 128 Feb 26 17:17 hosts.txt -rw-r--r-- 1 root root 2049 Mar 2 18:06 newdelldefault.crt root@OS10:/home/admin/cert_upgrade_script# chmod +x cert.sh
-
向每个交换机 IP 或根据自述文件与主机文件一起运行文件。
root@OS10:/home/admin/cert_upgrade_script# ./cert.sh -u admin -p admin -h 192.168.122.243 -c 192.168.122.243 Vulnerable root@OS10:/home/admin/cert_upgrade_script# ./cert.sh -u admin -p admin -h 192.168.122.243 192.168.122.243 Success root@OS10:/home/admin/cert_upgrade_script# ./cert.sh -u admin -p admin -h 192.168.122.243 -c 192.168.122.243 Not Vulnerable

运行脚本后,请查看 LKB 文章(Dell Networking OS10 证书到期和解决方案),了解后续步骤。
警报:根据 KB 步骤摆动 VLTi 或重新加载交换机,以使证书生效。

需要注意的项目
- 脚本会执行版本检查,查看运行的版本是否低于 10.4.3.x
- 如果运行的版本低于此版本,则会创建消息“运行的版本低于 10.4.3.x,请升级到较新版本”
- 脚本会检查 10.5.1.0 以上的版本。(在脚本版本 v4 中)
- 如果群集中的其他交换机也运行 10.5.1.0 或更高版本,则系统不易受到攻击
- 较新的固件可能已经影响证书,但它未在使用中,因此可以放心地忽略或升级
- 如果 Linux 上的用户名或密码中有特殊字符,请确保使用 '(单引号)。
- 如果现有 Linux作系统,请确保预期版本为 5.45 或更高版本
