导读 | 最近遇到一些FreeBSD的故障,在这种操作系统上我们平时用的一些无法执行,FreeBSD的一些配置文件也和其他很多Linux系统不一样。为了方便以后查阅,我特别整理了这篇文档。 |
1. 网络
重启网络的:
/etc/rc.d/netif restart , /etc/netstart restart
网络配置文件:
root@mhxy-compile02:~ # cat /etc/rc.conf ifconfig_em0="DHCP" sshd_enable="NO" ntpd_enable="YES" # Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable dumpdev="AUTO" zfs_enable="YES" puppet_enable="YES" ipv6_enable="NO" hostname="mhxy-compile02.i.nease.net" nfs_client_enable="YES" rpc_lockd_enable="YES" rpc_statd_enable="YES"
2. SSH
命令:
/etc/rc.d/sshd start , /etc/rc.d/sshd restart
SSH配置文件:
root@mhxy-compile02:~ # cat /etc/ssh/sshd_config # THIS FILE IS AUTOMATICALLY GENERATED BY PUPPET. # DO NOT EDIT THIS FILE. # 1. Basic Port 32200 Protocol 2 # 2. Authentication HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key KeyRegenerationInterval 3600 ServerKeyBits 768 UsePrivilegeSeparation yes LoginGraceTime 120 PermitRootLogin no StrictModes yes RSAAuthentication yes PubkeyAuthentication yes PermitEmptyPasswords no ChallengeResponseAuthentication no PasswordAuthentication no IgnoreRhosts yes RhostsRSAAuthentication no HostbasedAuthentication no # 3. Features UseDNS no X11Forwarding yes X11DisplayOffset 10 PrintMotd no PrintLastLog yes TCPKeepAlive yes AcceptEnv LANG LC_* # 4. Logging SyslogFacility AUTH LogLevel INFO # 5. x509 Subsystem sftp /usr/libexec/sftp-server #CACertificateFile /etc/ssh/ca/ca.cer
3. 防火墙
1)停止ipfw防火墙: ipfw disable firewall /etc/rc.d/ipfw stop 2)开启ipfw防火墙: ipfw enable firewall /etc/rc.d/ipfw start 3)清防火墙 ipf -Fa
4.赋予用户root权限
1)pw groupmod wheel -m 2)pw user mod -g wheel
5.查看CPU和内存
1)sysctl kern.smp.cpus或dmesg |grep cpu #查看CPU个数 2)dmesg|more或top #查看内存
