General :: Look For Specific Options In A Man Page?

Nov 18, 2010

I know that 'man gfortran' will get me the manual page for gfortran, but how do I lookup only the bit I want, which is '-Wall'? I can't find anything in the manual page for man.I could use 'man gfortran | grep -Wall' but that would return just a single line and not the whole paragraph.

Debian :: Modify /etc/fstab With SSD-specific Options?

May 31, 2010

I plan to:

- replace my hard drive with a 32GB SSD (solid state drive) SATA-II
- copy my entire old drive to the new one
- Both my drives will be Ext3 and have no swap (I have lots of RAM)

1. Can a Debian lenny desktop boot from an SSD ?
2. Do I have to modify /etc/fstab with SSD-specific options ?
3. How about grub, any modifications ?

Software :: Nemesis - Inject Packets With Specific TCP Options?

Jan 20, 2010

I want to inject a packet with specified TCP options: Maximum Segment Size, Window Scale Option, Timestamp Option... The man page mention very little about that:Quote:-o TCP-options-fileThis will cause nemesis-dns to use the specified TCP-options-file as the options when building the TCP header for the injected packet. TCP options can be up to 40 bytes in length. The TCP options file must be created manually based upon the desired options. TCP options can also be read from stdin by specifying '-o -' instead of a TCP-options-file.I don't understand what TCP options file structure is? ASCII, hex or raw? One way to try: in Wireshark, select the Follow TCP stream option of a packet, save as with some types: ASCII, hex... and use it for input:

Code:
sudo nemesis tcp -v -fS -D localhost -o /path/to/<TCP_options_file>
the output displays:

Software :: Unable To Change Page Size In Kivio Print Options

Jul 31, 2009

I am running OpenSuSE 11.0 KDE 3.5.9 "release 49.1" with Kivio 1.6.3. I am using Kivio to create large flow charts (paper size is 44in x36in) and I have an HP DesignJet 800PS that is capable of printing documents this size. We handle blue prints occasionally as well as when I have large documents (size wise) to print.

Anyhow I have a table relationship drawing I have created and I need to print it out. Now I have come up with a work around (save the document as PNG, import it into OpenOffice then save as PDF and print...) but when I try to print as PDF, I get the default paper size of A4 and the option to change the paper size is ghosted in Kivio. Also I only get a small segment of the actual drawing.

Ubuntu :: Gnome3 - Change Automount Options For A Specific Partition?

Sep 1, 2011

I have a specific NTFS partition on a USB drive that I wish to enable execute support for. The only way I've found to do this is to add the partition in /etc/fstab with a umask. This poses some problems:

1. Only root can mount it, making it a pain to mount (open terminal, `sudo mount (path from /etc/fstab)`, enter password, close terminal).
2. The system will hang at start if the UUID is unavailable (or, the external disk is unplugged). I run several servers from my machine, so if I do a remote restart it will not come back up because of the hang.

Is there a way to specify to FUSE (which I believe is the handler for auto-mounting in Nautilus) that this partition should have execute access to files?

General :: Run A Program For A Specific Amount Of Time Starting At A Specific Time?

May 18, 2010

I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.

Fedora :: Npviewer Segfaults - Firefox Sometimes Shows The Title Of A Page In A Tab But The Page Is Blank

Nov 23, 2009

On FC11 64 bit with Adobe flash plugin for Linux installed, I see segfault errors from "npviewer" in /var/log/messages. The only browser I have tried yet, Firefox, has glitches every now and then. Sometimes it shows the title of a page in a tab, but the page is blank. This can even happen when I try the Google main page. Is it true that npviewer has something to do with Adobe flash? Is there a way to fix the problem? If it is caused by Adobe flash, is there a different plugin that will replace Adobe flash player?

Hardware :: HP Deskjet 940c On Linksys Printserver Prints Alternating Good Page And Bad Page

Mar 9, 2011

I have a problem printing to my HP printer.

What is my problem? I have a page (one page - text an graphic) to print. When I sent it to my printer it prints OK. When I sent it agian, the output is totally garbled. When I sent it again (a third time) it is OK. Sent it again (4th time) it is garbled. Sent it again ... you get the picture ;-). Alternating good and bad pages.

What is my setup? I run Fedora 14 with Cups 1.4.6. The printer is a HP Deskjet 940C. It is connected to a linksys wireless print server. It is configured in CUPS to use ipp printing. The driver I use in Cups is 'CUPS+Gutenprint v5.2.6 Simplified (color, 2-sided printing)'.

Jun 8, 2009

But when I visit http:/localhost ,it shows up the list of files in <var/www/html> as if a ftp server browsed in web page. So how can I set http://localhost load my default web page index.html ?Second :I want to set up a web server on Internet through my router . I applied for DDNS account & input it into router correctly . I set virtual host in server to redirect any access from port 80 to 192.168.1.2:80 in LAN . Just for in case , I also download and running the DDNS software & installed it on PC 192.168.1.2 in LAN . My DDNS provider is oray.cn . It's a Chinese server provider .

So I want to know did I miss something to set up a web server in this kind of situation

Ubuntu :: Allow A Specific User To Mount Or Remount A Specific Partition?

Jun 9, 2010

my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)

Server :: Sendmail: Block Specific Sender To Specific Recipient?

Oct 1, 2009

I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.
