Bohemian Cowabunga posted:Thanks for the response, that was my question yeah. Not trying to be aggressive, but Linux doesn't do anything different than Windows or your router. You should probably read the book, since your background in network theory is somewhat shaky. Pseudo-random high ports, renegotiation (except for active FTP and other "old" services), embedding of the source/destination addresses/ports in the packet is all part of the standard. It's possible to cause a checksum collision in such a way that there's a conflict between traffic flows, but it's so unlikely that it'll probably never happen in your experience, and you wouldn't notice anyway (since TCP is a reliable protocol, it'll discard spurious packets and request missing ones).

evol262 posted:Whether or not anyone thinks it's an issue is one thing. TTYs are surprisingly complex, and there's a lot of accumulated cruft. The interaction between terminal emulator and TTYs isn't always intuitive, etc. It's a hard subject, and it's easier to just deal with it as a text stream. I'm not even aware of a native terminal emulator with this behavior. I'm sure the PuTTY guys would welcome patches. You aren't thinking far enough back into history. The original TTYs (Teletype terminals, essentially a keyboard attached to a printer instead of a screen) worked exactly like this. So the comedy option would be to set "export TERM=dumb", and output some blank lines to get to the bottom of the window. It is a comedy option because it will also disable most everything that uses ncurses or any sort of full-screen editing capability. For example, the "vi" editor will drop into traditional line editor "ex" mode. The best way to achieve what was asked would be to customize the shell instead of the TTY or anything associated with it. That way, any character-based software other than the shell won't be affected. If you throw this command in your .bashrc or .bash_profile, it will prefix your existing shell prompt with a terminal command sequence that moves the cursor to the bottom of the screen: code:

For those of you running linux on HP servers, how do you handle firmware patches? I've been using HPSUM to do this recently, and it is such a poorly made application, I wondered if there are any alternatives.

Oldest TTYs I've seen were serial, but VT100, so... I was under the impression that tputting the cursor will break line wrapping if your command is longer than the terminal width, hence my suggestion to query the TTY for its size and echo blank lines until you're there

ryo posted:For those of you running linux on HP servers, how do you handle firmware patches? The thing does seem pretty garbage. The easiest way to just install everything leaves a bunch of stuff you don't need on the system, like 8 different linux services but it also updates the firmware. I think there is a flag to not do that but the thing sucks. I know they have RPMs in a directory somewhere, but no idea if you can add it like a repository. I have been manually installing the raid tool to manage raid, and updated a couple machines offline booting the disk image. I remember for a while Dell had this well maintained RPM repo that you just installed and it would keep your firmware up to date with just yum upgrades. I don't know why they have to make it such a pain in the rear end.

How well is Ubuntu going to handle swapping mobo/cpu/ram from a 965 chipset mobo/q6600/4GB DDR2 to a z87 chipset mobo/i7-4770/16GB DDR3? Same answer if I decide to cheap out and instead use a z77/ivy bridge-era cpu? Will I need to do a re-install?

If I am listening to audio from a youtube video, I can load an mp3 also and get audio from both youtube and the mp3 on Windows. In Fedora only one application can do audio while the rest remain silent. Is this normal behavior? If not any ideas on what I can do to correct it? I don't know anything about sound/audio.

Looks like fedora should use pulseaudio. So what you want should work without trouble. The most likely problem is, that one of your 2 applications grabs full access to your soundcard ( that can still happen in Windows too, btw ). If it is a really old app causing the problem, that can be fixed by starting the application with padsp $appname, but that is normally too annoying to do. So check if pulseaudio is installed on your system. If it is, check if alsa does correctly rout audio to pulseaudio. For this you should use whatever gui fedora recommends. If you want to check the config yourself it should be in ~/.asoundrc or in /etc/asound.conf You are looking for a block like this: code:

I meant more that it would behave like hpux and start overwriting ps1 after 80-Len(ps1) characters. I haven't verified this, though it definitely happens if you tput around to write something below the prompt.

More newbie stuff: The MINGW32 console window won't accept backslashes, which is quote hampering to say the least. Same problem with many other special characters. I'm on English Windows, but with Danish keyboard and language. What can I do? Should I look to Cygwin if I want to dabble in the Linux commandline on Windows, or something else?

But curiously enough, for a fresh vncserver it's still using 200m, half of which is: 00007f8095c81000 102580 64 0 r---- locale-archive VmFlags: rd wr mr mw me ac 7f8095c81000-7f809c0ae000 r--p 00000000 09:05 136942 /usr/lib/locale/locale-archive Size: 102580 kB loving locales.

I'm having a problem when printing letter headed paper using duplexing (long edge). When the document is only one page long it prints on the side of the sheet opposite to the letter head. If it's two or more pages long all is well. I don't understand why it's changing the first side to be printed based on document length, is there any cups option that can be changed to avoid this? I'm using OpenSuse 12.1 but this problem also happens on 11.4 and NOT on 11.2.

Pilsner posted:Should I look to Cygwin if I want to dabble in the Linux commandline on Windows, or something else? Cygwin is nice if you just want to dip your toes or use some well-supported Linux programs in Windows. If you need binutils, cmake, diff, python, command-line svn/git, etc it's pretty much the easiest way from point A to B and scripts and such should mostly be portable. Most reasonably esoteric packages are there (eg python-numpy) but if you need something really out there you may have issues. If you end up having to build a bunch of dependencies from source your life is kinda going to suck. If you don't want any sort of a GUI you can do pretty well with Ubuntu Server inside Virtualbox, or you can just run a full-blown desktop distro in Virtualbox too (I like Lubuntu). Just set up some shared folders to what you need and you're good. Paul MaudDib fucked around with this message at 23:38 on Jun 10, 2013 |

How are you setting up VNC, and which variant are you using? I remember one version of VLC leaking a bunch of X windows all over the place, which would balloon into mutter tracking into a new window and backing pixmap every frame drawn.
