C gurus
by Chuck Haines Aug. 11, 2004

Aug. 11, 2004

For all you C gurus out there. I'm working on a little program that when an event occurs, it dials out a Verizon Wireless AirCard, does it's thing and then when all events are done, the last event close the card. To close the ppp connection you send it a Ctrl-C, which I'm doing, however it is never working. The code I'm using is as follows: void *sound_alarm ( void * rd_struct ) { RADSPY_STRUCT *ptr_rd_struct; ptr_rd_struct = ( RADSPY_STRUCT * ) rd_struct; /* lock the modem_in_use variable to check to dial modem */ pthread_mutex_lock ( &modem_mutex ); if ( modem_in_use++ == 0 ) { /* we need to dial out the modem */ printf ( "Dialing the modem: %d\n", modem_in_use ); modem_pid = fork(); if ( 0 == modem_pid ) { int ret; /* we are the child so dial out the modem */ ret = execl ( "/usr/sbin/pppd", "pppd", "call", "ac555qnc", NULL ); if ( -1 == ret ) printf ( "Problem dialing modem: %s\n", strerror ( errno ) ); printf ( "Got here.\n" ); exit ( 0 ); } /* hack to wait enough time to let the modem dial */ sleep ( 10 ); } pthread_mutex_unlock ( &modem_mutex ); /* perform the sending of the data */ printf ( "Sounding the alarm: %d.\n", modem_in_use ); sleep ( 1 ); /* code to send away alarms will go here, sleep for now */ /* release the modem in use */ pthread_mutex_lock ( &modem_mutex ); if ( --modem_in_use == 0 ) { /* we need to hangup the modem */ printf ("Hanging up the modem: %d\n", modem_in_use ); kill ( SIGINT, modem_pid ); } pthread_mutex_unlock ( &modem_mutex ); pthread_exit ( (void *) 0 ); } This function is a thread that is spawned by the main loop when an event occurs. This event can occur multiple times, which is why I have the shared variable of how many events are currently occuring (modem_in_use). When I run this program, I'm always getting an error about the modem being locked by pid XXX, so it's never being closed. Anyone have any experience with this kinda thing?

Multiple platform blues...
by Stephen C. Daukas Aug. 11, 2004

Aug. 11, 2004

I'm sure my experience with platform-dependent apps as an impediment to moving entirely to Linux is not unique. I have spent plenty of time playing with Linux at home, but have always had to deal with platform-specific needs of employers, etc., so I have never been able to completely immerse myself in Linux. I'd still like to use Linux as my primary platform, but I have to deal with having to run quite specific apps in different environments. So, I'm looking to begin a discussion about how to set-up a home environment that is as much Linux-based as is possible while providing for the realities of platform-specific requirements. Of course, this is as much a discussion of applications as it is about platforms. I have 3 systems and 1 laptop at home, all of which are Pentium IIIs, one as fast as 800MHz (imagine that!), that are available for use in my home network. I must be able to run Internet Explorer 6.x (required for several web-enabled apps I must use on a regular basis), Word, and PowerPoint. My wife has a Pentium III laptop that must run XP because of her work, but it would be nice to have her access a linux file server for backup and such. (She also likes Linux games!) Also, I have a couple of laser printers and an ink jet that I would rather hang off of one print server. With an eye toward a home network that must include Microsoft and access to Macs at work, here are some questions to start this discussion off: Q1 - OpenOffice versus MS Office: I will need to be reading/editing/creating Word and Powerpoint files (as most of the world do). I will be getting files to edit, and be creating others from scratch. I teach, so the results are intended for display on an ActiveBoard with the expectation of touching the board (or clicking from the console) to follow a link embedded in a powerpoint slide yielding a movie clip, or web page, or whatever. I'm told I have control over the department's files, but not to the extent of choosing something other than MS, so I'd like to use OpenOffice as my primary environment and then generate MS files for use at the school. I assume OpenOffice can do what PowerPoint can do (within reason), but I can't afford the time to "fix" generated MS Office files to work in a Mac or XP environment. Are the any OpenOffice users out there that can comment on this? Q2 - Heterogeneous access: I want to be able to access any file created in any of the three environments. I'd like to move files between the Macs at work and one or more of my machines at home without using Email (I want to avoid any constraints like size limitations on attachments). I want to be able to pull and push those files to whatever platform is needed for whatever needs to be done with them. I assume VNC is available on the Mac, and that I would probably need to run SAMBA, but what are the options these days? I suppose I could set up a FTP server... I'd also like to drop the static IP because of cost, and have already moved the web site to a commercial provider... Q3 - Email: Of primary concern is moving existing email from the MS environment (laptop) to Linux. I am trying to find a way to export all of my email from Mozilla 1.6 to a file or files that can then be moved to a Linux box and imported/read by a mail reader there, but I can't seem to find a way to do this... There is no export function in Mozilla 1.6 and the mail files are not consistently ASCII (at least from what I've seen). I have even tried to use other mailers' ability to import from their competitors, in the hopes that one of them can do the export, but I have had no luck with any of them knowing about Mozilla. Does anyone know of a way to get email out of Mozilla into an ASCII file-based structure (or something equally vanilla) that can be read by a standard Linux reader? Beyond that specific issue, what would be the best way to handle email? Right now I limit myself to using one platform and POP only from it. This is because I can travel with the laptop and not all the servers I access allow IMAP. I retrieve mail from 7 different accounts and forwarding is not allowed (nor do I want to have to keep track of that). I don't mind having to do this, but I'm wondering about other options... Thanks for your sage advice! Steve

Logitech QuickCam Pro and Programming
by Chuck Haines Aug. 10, 2004

Aug. 10, 2004

Hey guys, I recently got a Logitech QuickCam Pro and was thinking about doing some development work with it. I'd like to make a program that will take pictures when motion is detected or when I send it commands to do so. I'm currently looking to do it in C, so does anyone have any experience with this? I've done some googling and found some material but nothing that is really a how-to for the API for this kinda thing. Oh yea, I'm developing it on a laptop that runs Fedora Core 2, but I will eventually be porting it to an embedded computer (an Arcom GX-1 to be exact) which runs a flavor of RedHat 7.2 and kernel 2.4.18.

Graphing Package for Python.
by Chuck Noyes Aug. 3, 2004

Aug. 3, 2004

Hi all, I'm using version 2.2 python on a laptop running RH9; 2.4.23 kernel. I'd like to know what the 'list' considers a decent, and fairly easy to learn graphing package. I don't need anything too fancy, just a 2-D line graph package I can plug into python. I'd really like to stay away from object- oriented stuff, mostly because I don't understand it too well. Since the scripts I'm working on will probably be run on MS Windows as well as in Linux, the package will need to have a MS version too.

All fdisk /mbr does is replace your mbr with windows info...the most it would screw up is grub / lilo (what ever is in your mbr).

Well, if your only keeping your windows partition around to watch DVD's, that's something that you've been able todo in linux for a long time. Check out mplayer / Xine and Ogle. Tim. -----Original Message----- From: Gregory Avedissian [mailto:gma2004@verizon.net] Sent: Thursday, July 29, 2004 2:13 PM To: Worcester Linux Users Group Subject: Re: [Wlug] Partition table blues Here's the update: Went into BIOS and set the disk to LBA. This resulted in sfdisk -l showing the same geometry as the kernel (CHS 3737/255/63) This put the start and end of the first partition at 0 and 1023. Somewhere along the line, my windows partition grew by 2GB. Is it possible that it's reading a previous partition table? Win98 was still showing c: to be 5.8GB, and dos fdisk was still showing it as 8.2 GB. So, I took Doug's advice and said a prayer, then went at it. Set the win partition back to 6GB with dos (win98) fdisk (with the drive hooked up as master.) This made windows unbootable, and fdisk /mbr didn't correct it. That's ok. I did have it working again until then, and I could have retrieved my data if I'd had any on that partition. Connected the drive as slave and put another drive I had with a non-critical linux installation on as hda (in case I screwed up and partitioned the wrong drive). Booted into linux and repartitioned with sfdisk /dev/hdb, putting in parameters for <start cylinder> <size in cylinders> <type> for each partition when promted: /dev/hdb1 0 765 c * /dev/hdb2 765 130 82 /dev/hdb3 896 1044 (L for linux is the default) /dev/hdb4 1941 1795 (tried both 85 for linux extended and 5 for win extended) /dev/hdb5 1941 1305 L /dev/hdb6 - it insisted on setting up hdb6, so I just hit enter, and let it take the rest of the disk. This was originally unpartitioned space. I then was able to mount /dev/hdb3 and access my root filesystem. I was not able to mount /dev/hdb5 to access my /home partition. Error message from mount was "wrong filesystem type or too many mounted filesystems). Unless someone knows the secret code to to mount a recovered logical partition, I'll assume that there's no easy way to do it and finish this project (i.e. wipe the disk and start over, without putting windows on this drive.) No more extended partitions for this boy. On a brighter note, I learned how to get windows98 to boot from the SECOND hard drive, and that gives me great satisfaction. It was way easier than I thought, and if anyone's interested, I'll give details. This means that when I figure out how to watch movies on dvd in linux, I can get rid of windows by simply removing the second drive. Thanks to all for your help with this. Greg Charles R.

No, there's no lilo.conf and never was one on that installation. There is (was) a grub/menu.lst, which serves the same function, but as far as I understand it, the partition table needs to contain information about linux partitions for either of these to work. I went ahead and booted the rescue system and tried a grub-install /dev/hda, and it returned a message saying that no /dev/root was found. Maybe I'll try parted again, now that I can find where hda1 ends. Thanks, Greg

Partition table blues
by Gregory Avedissian July 25, 2004

July 25, 2004

Yup. I blew it away. I had win98 and suse 8.2 on the same hard drive, booting linux from floppy. Noticed that I could no longer boot windows from the hard drive, so I attemted to restore the mbr that I'd saved earlier. That didn't work, my partition table is gone, and I can't get there from here. Parted has a function called something like 'Guess at partition near START and END'. I assume it's looking for cylindar numbers. Is there a way to get those if I didn't write them down when I partitioned the drive? I do have the sizes of the partitions, to the nearest 0.1 GB. Looking for a free solution here. I did find a $90 solution that runs in windows and teases me by showing the files but not letting me copy or view them. Thanks, Greg

Problem with mount command
by Andy Stewart July 25, 2004

July 25, 2004

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, I have a problem with 'mount' between versions 2.11x and 2.12. Under 2.11x, this command worked just fine: mount -o port=3049,intr localhost:/null /crypt However, with the 2.12 version of mount, the command hangs and never returns. I have to kill the mount process to recover. Strace reports that the process is hanging at the "mount" call. Also, under 2.12, I do see entries in /var/log/messages indicating that a successful request was made to export /null: Jul 24 18:51:58 tux mountd[1843]: NFS mount of /null attempted from 127.0.0.1 Jul 24 18:51:58 tux mountd[1843]: /null has been mounted by 127.0.0.1 However, in another window, the "mount" command by itself does not show the NFS mount. All other NFS exporting/importing operations work just fine. The difference seems to be the two versions of mount and the use of the "port" option. I've downloaded the util-linux sources but so far cannot find a change that would effect this behavior. In case you are wondering what brought all of this about, I am trying to get my cryptographic file system (CFS by Matt Blaze) working under SuSE 9.1. I found a version of /bin/mount from another Linux system, and using that, I can access my files, but I really want to know why version 2.12 of util-linux broke/changed things. Any thoughts would be appreciated. Thanks!

nice use of graphics in a web page

Hi all I suppose this is a non-rant. I usually bitch about unecessary complexity in web sites. A friend showed me this one (he is a decendant of one of the kids kidnapped there by the French and Indians) and I thought the picture of the change with time of the area was very well done. http://1704.deerfield.history.museum/ doug

fetchmail/MS IMAP/8 bit
by Bill Mills-Curran July 22, 2004

July 22, 2004

I'm having troubles retaining special (8 bit?) encoding in email messages from the MS Exchange server where I work. Here's the normal path of my data: MS Exchange -> MS(?) IMAP -> fetchmail -> linux sendmail -> procmail -> mutt By the time an email with color fonts gets to mutt, the color is gone. As a test, I modified my .fetchmailrc to specify "cat" as my MDA so eliminated sendmail, procmail and mutt as offenders. I've also added "pass8bits" to my .fetchmailrc -- no improvement. Thus, I've narrowed the suspects to MS IMAP and fetchmail. Does anyone have experience with this problem? My environment: Redhat 9 fetchmail -V: > fetchmail -V This is fetchmail release 6.2.0+IMAP-GSS+NTLM+SSL+INET6+NLS Fallback MDA: (none) Linux esd-bcurran 2.4.20-30.9smp #1 SMP Wed Feb 4 20:36:46 EST 2004 i686 i686 i386 GNU/Linux Taking options from command line and /x/x/.fetchmailrc Idfile is /x/x/.fetchids Fetchmail will forward misaddressed multidrop messages to bcurran. Options for retrieving from CORP/x(a)x.com: True name of server is corpusmx1.us.dg.com. Protocol is IMAP. Password authentication will be forced. Server nonresponse timeout is 30 seconds. Default mailbox selected. All messages will be retrieved (--all on). Fetched messages will not be kept on the server (--keep off). Old messages will not be flushed before message retrieval (--flush off). Rewrite of server-local addresses is enabled (--norewrite off). Carriage-return stripping is disabled (stripcr off). Carriage-return forcing is disabled (forcecr off). Interpretation of Content-Transfer-Encoding is disabled (pass8bits on). MIME decoding is disabled (mimedecode off). Idle after poll is disabled (idle off). Nonempty Status lines will be kept (dropstatus off) Delivered-To lines will be kept (dropdelivered off) Received-message limit is 5 (--fetchlimit 5). Messages will be SMTP-forwarded to: localhost (default) Single-drop mode: 1 local name(s) recognized. No UIDs saved from this host. IMAP: Microsoft Exchange IMAP4rev1 server version 5.5.2657.74 TIA, Bill

USB mouse - left handed ?
by Andy Stewart July 21, 2004

July 21, 2004

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI gang, I am running a USB mouse on a RedHat 7.3 system (ancient version...don't ask...). In KDE 3.0, I use the GUI to change to left handed, but it has no effect. I also tried ' xmodmap -e "pointer = 3 2 1 " ' to no avail. Other than the fact that I cannot switch the two buttons, the mouse (trackball actually) works fine. gpm is not installed on this sytem, and I don't have root privs. Does anybody have any suggestions as to what else I should try (or rather, what else I should ask my sysadmin to try) ?

Just switch your fingers. Well, yes, but my fingers are already trained differently. :-) One one of my trackballs (ps/2), there's a DIP switch to do this swapping of left/right. However, the USB version of this trackball appears not to have the same functionality (CH Products DT225). > I just went into kde control center (suse 8.2), and there's a choice for > left-handed mouse.

invincible processes
by Gregory Avedissian July 19, 2004

July 19, 2004

I just had some strange stuff happen to my SuSE 8.2 installation - it's stalling when I try to copy files and run some programs. If I try to kill the process, it doesn't go away (kill -9 pid, as root), and the machine won't shut down because stuff is still running. This coincidentally happened the same day that I started to prepare a replacement hard drive, so it's not on a critical installation (in fact, it's going to be wiped), but I'd still like to know what's going on. Note that I totally disconnected this drive when I was installing on the new one, just to make sure I didn't do anything to hurt it. Any ideas on what this could be or where to look would be appreciated. Greg

Flowchart software
by Chuck Haines July 17, 2004

July 17, 2004

Does anyone know of any decent flow chart software for linux besides Dia or Kivio. Kivio is nice, however it's inability to export to a png or to be copy and pasted into star office makes it useless for me. Dia just doesn't cut it. Anyone know of anything?

Encrypted USB pen drive
by Chuck Haines July 15, 2004

July 15, 2004

Has anyone configured an encrypted usb pen drive under linux? I'm not talking about encrypting single files, but being able to mount the pen drive as an encrypted device? I've look at loop-aes, but I'm curious is anyone has done this before and might give some pointers.
