PuTTY Network Error: Software caused connection abort
I have a strange problem: When I'm using PuTTY with SSH connecting to a Linux server hosted in VMware on my local Windows 7, I often get the error saying and then the PuTTY SSH window is inactive. Usually I can login in the server with PuTTY and do something, but after a random time (about one or two minutes) I get that error. And sometimes I even can't login, getting an error saying timeout. I guess there's something wrong with my VMware Player, because I have another Ubuntu desktop hosted in VMware as a code repository server, and it more often than not has a timeout error when I do an SVN update/commit. However, I also guess Windows 7 has some quirk because the same Ubuntu server hosted in VMware as a code repository works very well when on Windows Vista! It seems all the bad things happen after I moved from Windows XP to Windows Vista and then Windows 7! What could be the reason for this problem and how can it be fixed? Supplement: I did a Google search and applied all methods to …

How to keep only every nth line of a file
I've got a rather sizable CSV file (75MB). I'm just trying to produce a graph of it, so I really don't need all of the data. Rewording: I'd like to delete n lines, then keep one line, then delete n lines, and so on. So if the file looked like this: and n=2, then the output would be: It seems like might be able to do this, but I haven't been able to figure out how. A bash command would be ideal, but I'm open to any solution.
Re-enter interactive mode after Ctrl-z
In interactive mode (in Octave, gnuplot, R, etc.) I occasionally press Control + z by mistake. This pauses the program and kicks me back to the terminal.

Count the number of words in a PDF file
How can I get the word count of a PDF file? I think that most pdf files for which I want to get total word count have text layer embedded, so I need no OCR. The task was arisen from searching for some scientific papers of known size, e.g. 15000 words. Most moders papers are published in pdf format

Vim Stuck In Insert Mode
I've been using Vim for several months now via my web host (they allow putty access). All of a sudden, the key has become unresponsive. I cannot exist insert or any other mode by simply hitting escape. I have to hit which brings up the help in vim and kicks me into command mode. I'm most certain that my escape key on my keyboard is functioning fine since all of my windows shortcuts that use the escape key operate normally. I know this is a ridiculous question and I'm certain there's a lot more to look into regarding a solution. What I really need is a solid lead as to where to start looking. Things that might help: I'm using vim via putty I'm logging in using jailshell I'm not root
How to search for only folders in Windows 7 instead of folders AND files
I've had some issues with the new search function in Windows 7. The Search in Windows XP was packed with so many more options. The only option I can access now are Date Modified and Size. Any pointers to how to get more options in the Windows 7 Search, or links to external programs that can make my life easier?
Mouse clicks suddenly stopped working in Ubuntu
This is a weird one. For some reason, last night my mouse partially stopped working. Movement is fine, but the mouse buttons don't work. Mainly it's the left button, but occasionally the right click and scroll-wheel fail too. Initially I thought it could be the mouse itself (the left button seemed to get a bit "soft" recently), but I tried another mouse and had the same issue. Both are USB wireless optical mice. The keyboard is working okay 95%, only problem is Alt+Tab doesn't seem to work. Both keys work fine independently. At the time it happened I was using Chrome, I dragged to scrollbar to scroll and when I released the mouse it was still holding scrollbar. I'm using Ubuntu 9.10, I upgraded weeks ago and everything was working fine so I don't think it's related to that. I also hadn't run any updates (I have now just in case something fixed it). But no luck. Any ideas?
What's the easiest way to sniff TCP traffic data on Linux?
I want a simple way to show all the TCP data (not the TCP headers or anything else) going over any interface on my Linux box. For instance, I want a magical command that if I do: then if there was a server listening on port 1234 on my machine, and someone did: Then the magical command would just print out: I've tried "tcpdump", "ethereal", "tethereal", "tshark", and others, but it isn't obvious how you get them to: not show IP addresses or other metadata only show the "data" being sent, not individual packets and their headers print the data as-is, not in hex, and not with packet-offset markers sniff all network traffic (whether it's on eth0 or eth1 or lo, etc...) Yes, you could probably string together a piped set of unix commands to do this, but that isn't very easy to remember for next time :) If you have a simple example of an exact command-line that does this, that's what I'd like.
How can I force Thunderbird to reload IMAP folder structure
Whenever I create a new label in my Gmail account, this creates a new IMAP folder. Sadly, that new folder does not show up in Thunderbird unless I restart Thunderbird. This is not specific to Gmail. When I create a new IMAP folder on my own server, the result is the same. To clarify. Here is what I'm doing. First, I create a new label in Gmail: But now it won't show up in my Thunderbird folder tree. Even though it knows about the folder and it is subscribed to: When I restart Thunderbird, the folder shows up just fine. I would like it to show up without restarting Thunderbird.

What characters are safe in cross-platform file names for Linux, Windows and OS-X
Currently, I use a name for most of my files. has spaces converted to underscores. I'd like to use the date format, but I am not sure how to separate it from the name. A would look strange if the name started with a number. If I use a , then it conflicts with the underscore representing a space. What characters are reasonably safe in file names that would work here? I am on Linux, but I might share files with other people (Windows 7, Mac OS X).
