Sender and receiver to transfer files over ssh on request?

阅读更多关于 Sender and receiver to transfer files over ssh on request?

问题 I created a program that iterates over a bunch of files and invokes for some of them: scp <file> user@host:<remotefile> However, in my case, there may be thousands of small files that need to transferred, and scp is opening a new ssh connection for each of them, which has quite some overhead. I was wondering if there is no solution where I keep one process running that maintains the connection and I can send it "requests" to copy over single files. Ideally, I'm looking for a combination of

Windows Mobile - What scripting platforms are available?

阅读更多关于 Windows Mobile - What scripting platforms are available?

We have a number of users with Windows Mobile 6 and need to apply minor changes. eg. update a registry setting. One option is push and execute an executable file using our device management software. I'd like this to be a little more friendly for the admins who are familiar with scripting in VBScript/JScript etc. What are the options for scripting on Windows Mobile devices? Once option that the devs over at xda-developers seem to enjoy is Mortscript I have never bothered to use it, but I have used many cab installers that distribute mortscript so that they can do various tasks I work on

Which Linux distribution should I use as a Xen host? [closed]

阅读更多关于 Which Linux distribution should I use as a Xen host? [closed]

I ordered a server for the home office and I would like to partition it with Xen. I think this will keep things clean and easier to maintain. I will be running things like MySQL, PostgreSQL, Tomcat, and my own code. What freely available Linux distribution has the best Xen hosting facilities? I highly recommend Debian or Ubuntu (server) for domain-0. Here's why: Setting up complex networking (bridges, bonded devices, etc) is simple. One file, easy syntax, easy to have scripts do it for you if need be. Do not use the 'network-bridge' script that comes with Xen on a production box, you may need

When could or should I use chmod g+s on a file or directory?

阅读更多关于 When could or should I use chmod g+s on a file or directory?

问题 In deploying to a new (Solaris 9) environment recently, one of the steps was to copy a set of files and directories to their new location and then to apply the group UID bit (using "chmod -R g+s") to all files in the directory tree giving a mode of -rwxr-s--- to everything. The result was that none of our shell scripts would execute unless they were individually opened and re-saved. I should add that we had earlier set g+s on the target parent folder prior to copying files; this had set the

How is it possible that kill -9 for a process on Linux has no effect?

问题 I'm writing a plugin to highlight text strings automatically as you visit a web site. It's like the highlight search results but automatic and for many words; it could be used for people with allergies to make words really stand out, for example, when they browse a food site. But I have problem. When I try to close an empty, fresh FF window, it somehow blocks the whole process. When I kill the process, all the windows vanish, but the Firefox process stays alive (parent PID is 1, doesn't

Crontab Day of the Week syntax

阅读更多关于 Crontab Day of the Week syntax

问题 In crontab does the Day of the Week field run from 0 - 6 or 1 -7 ? I am seeing conflicting information on this. wikipedia states 0-6 and other sites I have seen are 1-7 . Also what would be the implication or either using 0 or 7 incorrectly? i.e. would the cron still run? 回答1: 0 and 7 both stand for Sunday, you can use the one you want, so writing 0-6 or 1-7 has the same result. Also, as suggested by @Henrik, it is possible to replace numbers by shortened name of days, such as MON , THU , etc

Best way to sandbox Apache on Linux

阅读更多关于 Best way to sandbox Apache on Linux

I have Apache running on a public-facing Debian server, and am a bit worried about the security of the installation. This is a machine that hosts several free-time hobby projects, so none of us who use the machine really have the time to constantly watch for upstream patches, stay aware of security issues, etc. But I would like to keep the bad guys out, or if they get in, keep them in a sandbox. So what's the best, easy to set up, easy to maintain solution here? Is it easy to set up a user-mode linux sandbox on Debian? Or maybe a chroot jail? I'd like to have easy access to files inside the
