配置ProFTPD加密SSL

Posted on by yaoge123

下载脚本 http://www.castaglia.org/openssl/contrib/cert-tool ，修改cert-tool中openssl的路径，用这个脚本调用OpenSSL自签名颁发一个证书
cert-tool --create-ca=serverca --signing-ca=self
cert-tool --create-cert=server --signing-ca=serverca.cert.pem --signing-key=serverca.key.pem
修改proftpd.conf，增加TLS配置

TLSEngine on #开启TLS
TLSLog /var/log/proftpd-tls.log #TLS日志
TLSProtocol SSLv23 #允许使用SSLv3和TLSv1
TLSRSACertificateFile /usr/local/etc/server.cert.pem #cert-tool生成的证书
TLSRSACertificateKeyFile /usr/local/etc/server.key.pem #cert-tool生成的key
TLSCACertificateFile /usr/local/etc/serverca.cert.pem #cert-tool生成的CA证书
TLSVerifyClient off #不验证客户端证书。如要启用客户端证书验证，则需要用TLSCACertificateFile这个CA来颁发客户端证书
TLSRenegotiate required off #不强制要求重协商

另外加密传输需要使用FTP命令PROT，如果Deny ALL过，需要Allow
DenyAll AllowAll

Apache和ProFTPD的Order区别

Posted on (Updated by yaoge123
Order Allow,Deny Apache ProFTPD
仅匹配Allow Allow Allow
仅匹配Deny Deny Deny
没有匹配 默认Deny 默认Allow
匹配Allow和Deny 最后匹配Deny 首先匹配Allow

Order Deny,Allow Apache ProFTPD
仅匹配Allow Allow Allow
仅匹配Deny Deny Deny

FreeBSD下ZFS RaidZ硬盘替换扩容实践

Posted on by yaoge123

创建一个raidz1的ZFS pool
test# zpool create zfspool raidz da1 da2 da3
test# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
zfspool 23.9G 192K 23.9G 0% ONLINE –
test# zpool status
pool: zfspool
state: ONLINE
scrub: none requested
config:

zfspool ONLINE 0 0 0
raidz1 ONLINE 0 0 0
da1 ONLINE 0 0 0
da2 ONLINE 0 0 0
da3 ONLINE 0 0 0

用更大的da4、da5、da6替换原来小的da1、da2、da3 Continue reading →

FreeBSD下ZFS mirror升降级、硬盘替换和在线/离线扩容实践

Posted on by yaoge123

创建一个非冗余的ZFS pool
test# zpool create zfspool da1
test# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
zfspool 7.94G 110K 7.94G 0% ONLINE –
test# zpool status
pool: zfspool
state: ONLINE
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
zfspool ONLINE 0 0 0
da1 ONLINE 0 0 0

errors: No known data errors

增加一个盘，升级为双路mirror
test# zpool attach zfspool da1 da2
test# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
zfspool 7.94G 112K 7.94G 0% ONLINE –
test# zpool status
pool: zfspool
state: ONLINE
scrub: resilver completed with 0 errors on Tue Jul 21 21:24:27 2009
config:

NAME STATE READ WRITE CKSUM
zfspool ONLINE 0 0 0
mirror ONLINE 0 0 0
da1 ONLINE 0 0 0
da2 ONLINE 0 0 0

errors: No known data errors

如果想直接建立一个双路mirror的ZFS pool用
test# zpool create zfspool mirror da1 da2

再增加一个盘，升级为三路mirror Continue reading →

openSUSE 安装 VMware Tools 之前的准备

Posted on by yaoge123

openSUSE 11.2：
安装make, gcc, kernel-source
/usr/bin/vmware-config-tools.pl –clobber-kernel-modules=vmci –clobber-kernel-modules=vsock –clobber-kernel-modules=vmxnet3 –clobber-kernel-modules=pvscsi –clobber-kernel-modules=vmmemctl –clobber-kernel-modules=vmhgfs –clobber-kernel-modules=vmxnet –clobber-kernel-modules=vmblock

openSUSE 11.1：
删除/lib/modules/2.6.27.7-9-default/updates中的vmxnet.ko vmblock.ko vmmemctl.ko vmhgfs.ko vmci.ko vmsync.ko 这些文件
安装make, gcc, kernel-source

openSUSE 10.3：
安装less, psmisc, make, gcc, kernel-source

FreeBSD下PT client选择

Posted on (Updated by yaoge123

HDChina和HDBits上可用的client有Azureus、 BitTornado、 KTorrent、 rtorrent、 Transmission、 uTorrent。uTorrent需要Wine；Azureus(Vuze)和KTorrent需要X，因此都不考虑了。BitTornado 0.3.18 HDChina不认，Transmission 1.61 HDBits不认。rtorrent里凡是没有下载完成的任务，重启后都需要重新hash，Transmission则没有该问题，而且且速度比rtorrent要快。难道用uTorrent + samba？

FreeBSD使用VMware Tools无法关闭电源

Posted on (Updated by yaoge123

　　FreeBSD安装了VMware Tools以后，可以通过VI关闭客户机，但是系统停留在“The operating system has halted.Please press any key to reboot.”不能够自动关闭电源。解决方法为
ee /usr/local/etc/rc.d/vmware-tools.sh
　　查找vmware_start_guestd()可见
vmware_start_guestd() {
cd "$vmdb_answer_SBINDIR" && "$vmdb_answer_SBINDIR"/vmware-guestd \
--background "$GUESTD_PID_FILE"
}
　　在vmware-guestd命令下增加参数–halt-command “/sbin/shutdown -p now”，修改为
vmware_start_guestd() {
cd "$vmdb_answer_SBINDIR" && "$vmdb_answer_SBINDIR"/vmware-guestd \
--background "$GUESTD_PID_FILE" --halt-command "/sbin/shutdown -p now"
}
　　保存退出。执行 /usr/local/etc/rc.d/vmware-tools.sh restart，重启vmware tools即可。

FreeBSD下ZFS在线替换硬盘扩容实践

Posted on by yaoge123

替换前
test# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
zfspool 9.94G 1.96G 7.98G 19% ONLINE –

用da2替换da1，都是/dev/下的设备
test# zpool replace zfspool da1 da2

开始替换了
test# zpool status
pool: zfspool
state: ONLINE
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
scrub: resilver in progress, 15.24% done, 0h4m to go
config:

NAME STATE READ WRITE CKSUM
zfspool ONLINE 0 0 0
replacing ONLINE 0 0 0
da1 ONLINE 0 0 0
da2 ONLINE 0 0 0

errors: No known data errors

替换完成了
test# zpool status
pool: zfspool
state: ONLINE
scrub: resilver completed with 0 errors on Sat May 9 16:49:35 2009
config:

NAME STATE READ WRITE CKSUM
zfspool ONLINE 0 0 0
da2 ONLINE 0 0 0

errors: No known data errors

容量增加了
test# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
zfspool 17.9G 1.96G 16.0G 10% ONLINE –

整个过程中应用没有中断
