launchctl load...loads the FTP service into launchd's database of services. When you do an unload, you are telling launchd to not manage it anymore.

So a better way to do this--probably the proper way--is to first issue the command to load the service:

sudo launchctl load -w /System/Library/LaunchDaemons/ftp.plist

Then, if you'd like to stop FTP, issue this command:

sudo launchctl stop com.apple.ftpd

And if you decide you'd like to bring it back up, use this command:

sudo launchctl start com.apple.ftpd

If you'd like for launchd to forget about FTP, that is when you would run this:

sudo launchctl unload /System/Library/LaunchDaemons/ftp.plist

The hint as-is will work, but seems a little counter-productive to make launchd remember and forget about FTP all the time.

OS X: Change your PATH environment variable

Contributor Icon Contributed by qmchenry Date Icon October 2, 2007  
Tag Icon Tagged: Mac system administration  

When you run a command from a UNIX or UNIX-like shell, the shell looks for the executable file using the directories listed in your PATH variable as a map. For convenience, adding directories to this environment variable means you don’t have to go hunting for a file each time you run it. Following these directions will allow you to add a directory to the search PATH.


To change your path, you must edit the .profile file in your home directory. If you are comfortable using the vi editor, you probably don’t need to read any further. If not, then you can use TextEdit to edit your .profile.

The default .profile is fairly short. The .profile is read when you open a Terminal window and each line is executed just like typing a command into the Terminal window. While this is handy because you can make any available command run whenever you drop to a shell, we’re concerned with changing an environment variable, PATH.

In your editor, find the line that starts with export PATH= and give it a look to make sure it doesn’t already contain the directory path you’re going to add. Sometimes the PATH variable can get lengthy, but chances are yours just has a few directories separated by colons, perhaps something like this:

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

There are a few things to note before making changes. The format of this line is important. The use of spaces in this command, or their lack, matters. In particular, there cannot be spaces around the equals sign or between any of the directories. If there are spaces in the directory name you want to add, you’ll need to escape the space by preceeding it with a \backslash or by putting the path in quotes (export PATH=”/path/here”).

The export= keyword in front of that line has a very specific purpose. Defining a variable without exporting it makes it available only to the current shell, not to any subsequent shells. You may think to yourself that you don’t plan to make any subsequent shells, but this happens whenever you run a shell script. If the PATH variable was not exported, when you run a shell script, the PATH would no longer exist and it is possible that the script would fail.

The $PATH at the end of the example above tacks the previous value of the variable (if it exists) onto the end of the PATH. By default, this will add ‘:/bin:/sbin:/usr/bin:/usr/sbin’ to the end of the PATH for you which is useful because most everything you run from the command line lives there.

So, to add a new directory to the path, simply add it to the existing PATH line in .profile being careful to separate it from other directories there with colons and careful not to introduce unwanted spaces (everything after the space will be ignored). For example, to add the directory /mightyq/bin to the PATH shown above, the line could become any of the following examples:

export PATH=/mightyq/bin:/opt/local/bin:/opt/local/sbin:$PATH
export PATH=/opt/local/bin:/mightyq/bin:/opt/local/sbin:$PATH
export PATH=/opt/local/bin:/opt/local/sbin:$PATH:/mightyq/bin

Note that in the third example the new directory is added to the end of the PATH. You have the ability to optimize the searches your shell will do on your behalf each time you run a command by organizing your PATH logically. Putting less frequently used or really massive directories later in the path may give you a little performance boost (although these days things are pretty fast, so you have to be a little anal to really enjoy this).

If you don’t need a directory in your path, you can reverse the process by deleting the unwanted directory still taking care to preserve the no spaces, colon separation rules.

One last note, to test the change you made, you can use the echo command, but you need to make the shell reload the .profile first. Assuming you are in your home directory (if not, running ‘cd’ without any options will take you there), run these commands:

. ./.profile
echo $PATH

The first is a neat little command in that it shows three uses or interpretations of the period in a single line. The first . is a shortcut to cause the shell to ’source’ or load the contents of the subsequent file as itself, in the manner that the shell uses when you login to a system or start a Terminal window. If you simply executed these commands like a shell script (bash .profile, for example) you would start a new shell, that shell would get the variable set, and at the end of running the .profile script, that new shell would cease to exist and the newly defined variables would be relegated to the missing sock universe.

The second period means the current working directory. It’s not compulsory in any way in this command, but it’s habit from explaining the dots to folks, so I type it all the time now. In this context, you could also use ~/.profile as ~ explicitly means your home directory.

The last dot causes the .profile to be hidden from view in a normal directory listing or Finder view. It doesn’t change the file in any other way, it just make it invisible and de-clutters your directories. To see hidden files, you can use ‘ls -a’ and you might be surprised by what you find.

SafeNet SoftRemoteLt on Windows 7

Posted by CKret on September 16, 2009

At our company we use SafeNets SoftRemoteLT VPN solution for secure communication with our DB servers.
In Windows XP and Vista this works fine.

Since the release of Windows 7 RC I’ve tried to get SoftRemoteLt working but have had no luck.
That is until now…

In this post I will show you how to configure Windows 7 and Virtual Windows XP Mode to route VPN traffic through XP.

First you need to make sure you’ve got the prerequisits:
(Instructions for prerequisits are not covered by this post.)

  • Windows 7 Professional or Ultimate
  • Intel® Virtualization Technology or AMD-V™ feature is enabled in BIOS
  • Windows Virtual PC RC
  • Windows XP Mode RC
  • SafeNet SoftRemoteLt installed on Virtual Windows XP.
    These instructions should work for other clients as well.
  • Make sure Internet and VPN is working.

(Windows Virtual PC RC and Windows XP Mode RC can be downloaded from here.)

There are several things we need to configure on both Windows 7 (host) and Windows XP Mode (guest):

  1. Add a Loopback adapter to the host.
  2. Configure the Loopback adapter.
  3. Add a Virtual adapter to the guest.
  4. Configure the Virtual adapter.
  5. Disable Internet Connection Sharing and Firewall on the guest.
  6. Enable routing on the guest.
  7. Configure routing on the guest.
  8. Configure routing on the host.

Let’s get started then.

Add a Loopback adapter to the host

For the host to utilize the VPN located on the guest we need more than unidirectional communication.
VPN traffic goes from the host to the guest, thrugh the VPN and out on the Internet.
When receiving data the guest needs to be able to route it back to the host.
Therefor we need another communication channel.

  • Open up Device Manager and right click the root node.
  • Select “Add Legacy Hardware” then click “Next”.
  • Select “Install the hardware that I manually select from a list (Advanced)” and click “Next”.
  • Select “Network Adapters” then click “Next”.
  • In the left pane select “Microsoft”.
  • In the right pane select “Microsoft Loopback Adapter” then click “Next”.
  • On the confirmation screen click “Next”.
  • When the installation is finished, click “Finish”.

Now you should have a new network adapter in the Network Connections.

Configure the Loopback adapter

Now it’s time to choose a subnet and IP address for your network connection.
I chose a subnet that wouldn’t collide with my home or work networks.

192.168.199.199 with subnet mask 255.255.255.0

  • Open up the Network Connections.
  • Find the new network adapter.
    Mine is called “Local Area Connection 4″.
  • Right click the icon and select “Properties”.
  • Select “Internet Protocol Version 4 (TCP/IPv4)” then click “Properties”.
  • Select “Use the following IP address”.
  • Enter the IP address and subnet mask and click “OK”.
  • Click “OK”.

We’re almost done configuring the host. However, before we can finish we will configure the guest.

Add a Virtual adapter to the guest

Before we start you’ll need to shut down Windows XP Mode completely. Hibernation will not work.

  • Open up Virtual Machines.
  • Select “Windows XP Mode”.
  • Click “Settings”.
  • Select “Networking”.
  • Set the number of network adapters to 2.
  • For the second adapter, select “Microsoft Loopback Adapter” then click “OK”.

Moving on…

Configure the Virtual adapter

For the Virtual Adapter we should now choose an IP address in the same range as we chose before:

192.168.199.200 with subnet mask 255.255.255.0

  • Start Windows XP Mode.
  • Open up Network Connections.

You should now see two connections. Mine are called “Local Area Connection” and “Local Area Connection 2″.
The first one is your “Internet Connection” and the second one is the “Loopback Connection”.

  • Right click your “Loopback Connection” then select “Properties”.
  • Select “Internet Protocol (TCP/IP)” and click “Properties”.
  • Select “Use the following IP address”.
  • Enter the IP address and subnet mask and click “OK”.
  • Click “OK”.

Disable Internet Connection Sharing and Firewall on the guest

We need to create or own routing and we do not want windows to interfere with our setup.

  • Open “Services”.
  • Find “Windows Firewall/Internet Connection Sharing (ICS)”.
  • Right click the node and select “Properties”.
  • Set “Startup type” to “Disabled” then click “Stop”.
  • Click “OK”.

Don’t close “Services” just yet.

Enable routing on the guest

To enable routing we need to do two things:

  • Start RegEdit.
  • Find the key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IPEnableRouter”
  • The default value should be “0×00000000″, change it to “0×00000001″.
  • Close RegEdit.
  • Back in “Services” find “Routing and Remote Access”.
  • Right click the node and select “Properties”.
  • Set “Startup type” to “Automatic” then click “Start”.
  • Click “OK”.

You may now close “Services”.
At this point you might need to restart Windows XP Mode.

Configure routing on the guest

In this step we’ll set up the routing needed for the host to be able to communicate through the guests VPN.

  • Start a “Command Prompt”.
  • Enter “netsh routing ip nat install”.
    This will install NAT routing.
  • Enter “netsh routing ip nat add interface “Local Area Connection” full”.
    This will route traffic through your “Internet Connection”.
  • Enter “netsh routing ip nat add interface “Local Area Connection 2″ private”.
    This will route traffic through your “Loopback Connection”.

Guest is done! Only one more thing to do.

Configure routing on the host

You’ll need to know which subnet your VPN network is using.
We will configure the routing so that all traffic meant for your VPN network goes through the “Loopback adapter”.
Let’s say your VPN subnet is

172.16.16.0 with netmask 255.255.255.0

  • Start a “Command Prompt” as Administrator. (Run as Administrator).
  • Enter “route -p add 172.16.16.0 mask 255.255.255.0 192.168.199.200″
    Note that 192.168.199.200 is the IP address of the guests Virtual Adapter we set earlier.

All done.

From now on all you need to do is start SoftRemoteLt from the “Windows Virtual PC” folder in the Start Menu and you’re all set.

依次排除法：
1，中毒，我机器装的有Rising，我觉得很不错，虽然很多人说不好，我相信他，直接跳过。
2，驱动，我试过重装显卡驱动，因为一开始我显卡驱动不对的时候，无法休眠，我想这个可能有点关系。
3，BIOS设置，我分别设置过SATA和Security chip的相关设置，都无法成功解决。
4，硬件问题，我无法测试，但我相信我的火气不至那么好！

开启miniDump，收集日志。并用WinDBG分析，发现77号错误，网上的提示和Microsoft的分析均无法对应上。
想了想，自己先删掉我之前装的RamDisk4G试试。

在我成功移除RamDisk4G建立的fix media后，重启，OK，一切搞定！

看来想用到4G的内存，还是用64位的OS比较靠谱！

1，确认/etc/default/rcs文件中的utc=yes。
2，使用hwclock --directisa直接查看BIOS的时间是否正确。如果不正确，请将其设定正确。
3，使用hwclock --directisa --hctosys命令，将系统时间同步成BIOS的时间。
4，使用hwclock --directisa --systohc命令，将BIOS时间同步成系统时间。
5，reboot系统检查。 

注：命令中加有--directisa参数，是为了避免可能出现以下错误：

注意裸设备的名字，以上面例子为例，mklv时使用contest为lv名称，创建表空间时则应使用对应的裸设备名称rcontest。
裸设备的大小计算方法为：
首先用命令lslv lv名看PP Size大小，再用PP Size乘以lv大小。如PP Size为8M，lv大小为10，裸设备大小为80M(80M/4K=20000页)。

一，安装JAVA6

1，用root用户登录到AIX系统中。
2，使用如下命令确定操作系统位数：
  bootinfo -k
  如果结果为：3，则表示AIX系统为32位，请勿安装64位的JVM。
3，用mkdir /tmp/jvm命令建立一个目录，并将Java6.sdk（如果是64位的AIX，推荐选用Java6_64.sdk）用FTP上传至/tmp/jvm目录中。
4，键入smit命令，进入如下画面：

12，安装验证，使用如下命令：
 /usr/java6/bin/java -version

得到如下结果，说明安装正确完成。
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap3260sr4ifix-20090417_02(SR4+IZ48590))
IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 AIX ppc-32 jvmap3260sr4ifx-20090409_33254 (JIT enabled, AOT enabled)

JIT  - r9_20090213_2028
GC   - 20090213_AA)
JCL  - 20090228_01

 

二，环境变量配置：
1，由于AIX在安装的过程中，会默认安装JAVA1.4，所以需要先删除/etc/environment文件中，PATH环境变量中的/usr/java14/jre/bin:/usr/java14/bin。
2，编辑/etc/profile文件，在PATH变量中，加入/usr/java6/jre/bin:/usr/java6/bin两项，并在文件未尾加上如下一行：
 export JAVA_HOME=/usr/java6
3，重新用root用户登录，以使环境变量生效。
4，验证，使用java -version命令，得到如下结果：
java version "1.6.0"
Java(TM) SE Runtime Environment (build pap3260sr4ifix-20090417_02(SR4+IZ48590))

需要多说一句的是，清除此告警灯之前，确定你的机器的告警信息已经处理掉了，否则就失去设置此灯的意义了。

1、输入命令 diag
2、选择 Task Selection.
3、选择Log Repair Action.
4. Select the device that was repaired.（直接在第一项回车选择即可，按F7提交执行）
5. Press F10 to exit diagnostics.


If the attention LED remains on after you have completed the repair action and reset

1,cd /usr/share/fonts
2,mkdir truetype
3,cd truetype
4,mkdir simsun
5,使用FTP或SFTP将Vista下的simsun.tcc文件传到/usr/share/fonts/truetype/simsun/目录中
6,执行 mkfontscale
   生成了fonts.scale文件
7,执行 mkfontdir
   生成了fonts.dir文件
8,chkfontpath --add /usr/share/fonts/truetype/simsun/
9,service xfs reload
此时，使用Window方式登录，语言选择中文，即可正确显示中文了。

不是，原来是你必须在root用户下才能使用这个命令。

2，使用mount命令直接挂载一个ISO文件，示例如下：
mount －o loop fc8.iso /mnt/fc8

3,FTP(VSFtpd)服务默认不让root用户访问的解决办法：
去掉/usr/vsftpd/user_list文件中的“root”那一行。
在这个文件中的用户是被禁止的。

闲逛中发现了Solaris安装宝典，所以拿来与大家共享。

有空的朋友可以下载下来安装一下，顺便也学习一下。
近段时间老在网上看到“如果没有D版的WINDOWS可用怎么办？”的讨论。
还有做开发的朋友我想也应该经常看到招聘条件上总写着熟悉Linux或Unix系统之类的话。

不多说了，文件下载地址如下：

PS：前段时间操作一套客户的环境，全是solaris的OS，搞得我现在想起退格的时候都还只往DELETE键上按。

2008.1.21.
本周来学习后台命令：
cron 系统调度进程。使用它在每天或一个循环周期中完成作业。
At 使用它在一个特定的时间运行一些特殊的作业。
＆　使用它在后台运行一个占用时间不长的进程。
Nohup 使用它在后台运行一个命令，即使用户退出时也不受影响。

crontab命令允许用户提交、编辑或删除相应的作业。每一个用户都可以有一个crontab文件来保存调度信息，系统管理员通过cron.deny和cron.allow这两个文件来禁止或允许用户拥有自己的crontab文件。
crontab的域：
分钟　小时　日　月　星期　要运行的命令
可以用－来表示一个时间范围，域中可以用逗号(,)表示多个选项，用＊表示连续的时间段。
命令格式：crontab [-u user] -e -l -r

根用户可以通过/etc目录下的at.allow和at.deny文件来控制哪些用户可以使用at命令，哪些用户不行。
at命令格式：at [-f script] [-m -l -r] [time] [date]

nohup命令格式：nohup command &
默认会将该作业的所有输出重定向到一个名为nohup.out的文件中，可以指定输出文件，如下：
nohup command >myout.file 2>&1

2007.12.28
find命令的一般形式为：
find pathname -options [-print -exec -ok]
-exec表示命令对匹配的文件执行该参数所给出的shell命令。相应的形式为'command' {} \;
-ok跟-exec差不多，但执行前会提示用户确定是否执行。
options有很多选项，其中有以下一些项目：name,perm,prune,user,group,mtime -n +n,nogroup,nouser,newer file1 !file2(查找更改时间比文件file1新但比文件file2旧的文件),type,size n[c],depth,fstype,mount,follow,cpio(对匹配的文件进行备份，到磁带设备中).

样例：
查找文件名以a或b开头的，可执行文件，并调用ls命令显示其详细信息
find . -name '[a-b]*' -perm 755 -exec ls -l {} \;
查找更改时间为5天内的文件
find . -mtime -5
列出所有的目录名
find . -type d


xargs可以使用户对所匹配到的文件执行几乎所有的命令，而不会受到命令长度的限制。如：
find . -name '*.txt' -type f|xargs grep "ttt"
搜索所有txt文件，并找出这些文档中存在ttt字串的文件。

我选用的版本是：Lynx 2.8.5

1、先下载ZIP档，然后用unzip 命令解压。
$unzip lynx-2.8.5.zip
2、进入安装目录：
$cd lynx-2-8-5

3、安装命令如下：

./ configure  -- prefix =/ usr  -- libdir =/ etc  -- without - ssl  -- with - zlib  &&
make  &&
make install  &&
make DOCDIR =/ usr / share / doc / lynx - 2 - 8 - 5 / lynx_doc  \
   HELPDIR =/ usr / share / doc / lynx - 2 - 8 - 5 / lynx_help install - doc  &&
make DOCDIR =/ usr / share / doc / lynx - 2 - 8 - 5 / lynx_doc  \
   HELPDIR =/ usr / share / doc / lynx - 2 - 8 - 5 / lynx_help install - help  &&
sed s / " t\/etc " / " t\/usr\/share\/doc\/lynx\-2\-8\-5 " /   \
    / etc / lynx . cfg  >   / etc / lynx . bak  &&
mv  / etc / lynx . bak  / etc / lynx . cfg

安装时需要GCC支持，也需要SSL支持(可选)，上面这个命令就是不带SSL支持的。
要想带SSL支持的话，把命令中的--without-ssl改为--with-ssl即可。

4、执行命令测试：
$lynx http://localhost:7001/console
看看WLS的控制台是不是出来了？

详细的安装文档可以查看安装包中的INSTALLATION文件。
我有试过，在linux下面安装也完全相同，我用的是liunx FC5。

附：
一、如果目前的Solaris环境中没有安装GCC，可以参考下面的步骤：
1 取得针对操作系统和操作系统版本保持一致的GCC软件
如果你要在Solaris 9上使用GCC，要取得相映的GCC
ftp://ftp.sunfreeware.com/pub/freeware/sparc/9/gcc_small-3.3.2-sol9-sparc-local.gz
 
2 解压缩
.gz表示是这是一个经过GZIP压缩过的文件。需要用gzip/gunzip软件首先解压缩。
$ gunzip gcc_small-3.3.2-sol9-sparc-local.gz
  
3 安装
解压缩之后的就是安装包。在solaris操作系统中安装包有一套专门的命令和程序
#pkgadd -d ./gcc_small-3.3.2-sol9-sparc-local.gz
在接下来的安装中，会有一个交互性安装过程。
  
4 调试
以gcc-3.3.2为例，GCC缺省安装的路径为/usr/local/bin，这个路径可能不在
用户的PATH变量表示的范围内，所以需要对PATH变量更新，方便使用GCC。
对使用csh的用户：
% setenv PATH=$PATH:/usr/local/bin
对使用sh的用户：
$ PATH=$PATH:/usr/local/bin
$ export PATH

二、如果提示 "make not found"
make是装在/usr/ccs/bin/make
$PATH=$PATH:/usr/ccs/bin
$export PATH

三、如何查看OpenSolaris/Solaris的版本信息?
通常的“uname -a"命令就可以知道Solaris的版本:
想知道是哪一个Solaris Update版本，可以查看/etc/release文件。
对于曾经使用过Opensolaris的BFU升级的用户，应该查看/etc/motd文件。

Solaris版本        SunOS内核版本        发布日期                                                  简介                      
Solaris 10              SunOS 5.10              2005年1月31日     包括DTrace (动态跟踪), Solaris Containers, Service Management Facility

就像帮我的那位同事说的一样，没事他就在AIX下用man来一个个的看这些命令，我觉得这个方法好，先试着采用一下，然后再来解决一些问题。

2007.11.26
这周先从ls命令学起，正好早上也在帮同事用这个命令解决问题。
以下是比较有用的一些操作：
ls -lS   按文件的大小排序
ls -lS --block-size=1K 将文件信息以K为大小单位排序列出
ls -F 文件后面跟一个类型符＜“*”表示可执行的普通文件；“/”表示目录；“@”表示符号链接；“|”表示FIFOs；“=”表示套接字(sockets)＞

2007.12.3
上周后来又学了很多命令，如下，记录在此：
chmod 改变文件权限，会经常用到的。
chmod [who] operator [permission] filename    chmod命令的相对模式
chmod [mod] file                                             chmod命令的绝对模式，我更喜欢这种模式

chown改变文件属主
chown -R -h owner file
-h表示在改变符号链接文件的属主时不影响该链接所指向的目标文件

chgrp改变文件所属的组
chgrp groupname filename

找出用户所属的组可以用group和id命令

软链接命令ln
ln [-s] source_path target_path
常用的场景可能是目录太深；一份文件，多人看；应用程序的日志，指定到一个自己想要的目录，可以建一个指向该目录的链接，这个用法可能最实用，也用得最多，例如：WAS指定LOG的目录为/opt/webshpere/profile/server1/log/，我想把日志都写到/usr/log/中，可以用这样的命令：
ln /opt/websphere/profile/server1/log/ /usr/log/
这样就OK了，呵呵，好强呀!这个Windows下面肯定是不支持的。

cd ~ 这个是回到用户的默认目录

我们知道启动WebLogic一般用 startWebLogic.sh命令，这个命令执行后，WebLogic的Log就会出现在Shell窗口中，而且这样的话，不能关闭这个Shell进程，一关闭的话就会shutdown掉整个WLS。

在Ubuntu中，我用以下命令来解决这个问题：
nohup ./startWebLogic.sh >>t.log &

可是，我在SunOS中，用这个命令可不起作用了。总是提示“已经输出到nohup.out中”
我只好用以下命令来搞定：
./startWebLogic.sh >>t.log

然后，我可以用
tail -f t.log
这个命令来查看LOG。

各位兄弟姐妹们知道为什么在SunOS中，nohup不起作用吗？

今天折腾了一天，到现在已经是晚上十点了，终于在我工作的机子上装上了FC6，我的机子是ACER的品牌机，SATA的硬盘，USB的键盘鼠标，所以很多Linux的版本是不能用的，比如同事带的RedHat9就是不支持SATA的，上午折腾了大半早上，就只弄清楚了这个问题，所以马上去下载FC6，由于公司的网络是有封锁的，还好我用的这个IP不是全封，找了好久才找到一个可用的下载地址，那下载速度可真是慢呀。

到了晚上下班的时候，终于快下完了，可以发现现在的版本的中再也不带以往常用的DOS启动的文件了，去网上查了些资料，终于弄清楚怎么安装了。简要记录如下：

1、先去SF.NET上下载一个WINGRUB，当然需要你的系统中有一个XP或是2000的系统，安装很简单，配置也超简单，Windows下这点还是蛮好的，这里不再多说，确保你的系统能用GRUB的方式启动就好了。
2、用一个虚拟光驱之类的软件把你下载的ISO文件第一张盘的isolinux目录下的vmlinuz和initrd.img两个文件COPY到C盘的根目录（当然其它目录也可以，不过呆 会儿在启动FC的安装程序的时候自己记得改下地址就好了）。
3、重启系统，这时你会看到GRUB的启动菜单，按“C”键，进入GRUB的命令行。
4、键入以下命令：
    GRUB>kernel (hd0,0)/vmlinuz
    GRUB>initrd (hd0,0)/initrd.img
    GRUB>boot
5、OK，顺利进入FC6的安装程序，你可以选择语言和安装程序的位置。
