Network problems on new FC4 box - please help.
by William W. Austin 15 Dec '09

15 Dec '09

I had to replace a disk (the one with all of the home directories on it) on an FC3 box, and so I bought a new drive (particulars unimportant). To make a long story short, I decided to put FC4 on this box, and so I installed the new drive and put the root filesystem on it. I still have the old FC3 root drive and can boot to either for comparison... Under FC3, I have no network problems that I can detect; however, under FC4 there are two distinct (related? no idea) problems which have eluded me. I have tried looking up both of these in the archives, but have had no luck (some similar issues, but nothing exactly like either of these unless I missed them). Problem 1: network card goes to sleep. This machine has 2 network cards, both on-board. The 1GB card L(Intel 82540EM) goes to the smartswitch to tolk to the local network, and does not show any problems. The other card (nVidia nForce2) is a 100MB card and talks to the DSL modem. Periodically I cannot connect to the internet at all - or even ping the DSL modem. This happens irregularly but about 5-10 times/day. If I reboot back to FC3, the problem does not occur. Network configurations between the two (FC3/FC4) are as identical as I can make them. The first few times the problem occurs, sometimes retarting networking works, but eventually a full sys reboot is the only thing which works. Problem 2: slow local network. Under FC3 throughput on the LOCAL network (1GB lan) is very fast. Under FC4, the best I have seen is ONE transfer of about 1.2 MB/s - and throughput drops to as low as 50-75KB/s at times. Again, this does not occur under FC3 but does under FC4. Again the same setup as nearly as I can make it. No workaround found so far. Any suggestions would be greatly appreciated. -- william w. austin waustin(a)speakeasy.net "life is just another phase i'm going through. this time, anyway ..."

X and Intel 965
by Jeffrey Ross 22 Oct '08

22 Oct '08

so far the installation of FC6 has gone relatively smoothly albeit some additional learning and bumps due to the 64 bit architecture of this machine. The mother board is an Intel DG965RYCK which uses Intel's 965 express chipset. Based upon what I've been able to find on the web, Intel has released the drivers for this chipset to OSS, although there have been issues as to what Intel actually released and how complete they might be. Regardless I unable to run mplayer (or Realplayer) for that matter without the display first freezing then going black followed by garbage along the bottom of the screen. A Control-Alt-Backspace does not stop X from running. The only way to recover the machine from this point is to reboot the system. I am still able to connect from a remote system, its just the display that has become unstable. lspci -v shows the following for the graphics adapter 00:02.0 VGA compatible controller: Intel Corporation Integrated Graphics Controller (rev 02) (prog-if 00 [VGA]) Subsystem: Intel Corporation Unknown device 514d Flags: bus master, fast devsel, latency 0, IRQ 177 Memory at 50200000 (32-bit, non-prefetchable) [size=1M] Memory at 40000000 (64-bit, prefetchable) [size=256M] I/O ports at 3110 [size=8] Capabilities: [90] Message Signalled Interrupts: 64bit- Queue=0/0 Enable- Capabilities: [d0] Power Management version 2 suggestions would be appreciated. Thanks

OFF-TOPIC: Fedora 7 already installed, can't install XP on empty partition
by Andre Costa 19 Sep '08

19 Sep '08

Hi, this is somehow off-topic, but hopefully someone here has been through this already... I just bought a shiny new Core 2 Duo machine (Intel DG33BU mobo), with a nice 250G SATA disk. Fedora 7 installation went surprisingly well (and fast), only problem was that onboard NIC was not recognized, but upgrading the kernel offline fixed this. Everything is amazingly fast =) BUT... I need this machine to dual-boot to Windows XP (still addicted to some Windows-only games =( ). XP setup CD hangs just after showing "examining hardware configuration" or something like that. It doesn't really hangs, it just switches to a blank screen and sits there forever (I already left it there for more than 15min to no avail). Keyboard is responsive and HD led stays on. CTRL+ALT+DEL reboots as expected. I talked to IT guys at work and they told me they've been through this already lots of times, it seems XP is unable to properly recognize the disk when only Linux is installed on it (?!?), and only solution would be to reformat the whole thing and install XP first. Is that true? My system is configured as: ~ fdisk -l /dev/sda Disk /dev/sda: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 10467 83971755 8e Linux LVM HD specs are: ~ hdparm -I /dev/sda /dev/sda: ATA device, with non-removable media Model Number: SAMSUNG SP2504C Serial Number: S09QJ1SP208120 Firmware Revision: VT100-50 GRUB is installed on MBR. All remaining space is sitting there, waiting for XP to take over... =/ Anyone knows of a workaround? Should I try to create an additional partition on the empty space and format it as VFAT hoping this would make Windoze less stupid? Or am I doomed to remove all partitions and start from scratch, starting with XP? TIA Andre

vstpd.conf

Im having a devil of a time getting vsftpd configured for auth. with an ldap backend on Fedora Core 5. I keep getting a 530 530 Login incorrect. Unable to make a connection. Please try again. The server has a username incorrect message. Anonymous works fine. I have standard vsftpd.conf here is the snippet: anonymous_enable=No # # Uncomment this to allow local users to log in. local_enable=YES # # Uncomment this to enable any form of FTP write command. write_enable=YES # # Default umask for local users is 077. You may wish to change this to 022, # if your users expect that (022 is used by most other ftpd's) local_umask=022 # # Uncomment this to allow the anonymous FTP user to upload files. This only # has an effect if the above global write enable is activated. Also, you will # obviously need to create a directory writable by the FTP user. #anon_upload_enable=YES # # Uncomment this if you want the anonymous FTP user to be able to create # new directories. #anon_mkdir_write_enable=YES # # Activate directory messages - messages given to remote users when they # go into a certain directory. dirmessage_enable=YES # # Activate logging of uploads/downloads. xferlog_enable=YES ascii_upload_enable=YES ascii_download_enable=YES # # You may fully customise the login banner string: #ftpd_banner=Welcome to blah FTP service. # # You may specify a file of disallowed anonymous e-mail addresses.

If chroot_local_user is YES, then this list becomes a list of # users to NOT chroot(). chroot_local_user=YES #chroot_list_enable=YES # (default follows) #chroot_list_file=/etc/vsftpd.chroot_list # # You may activate the "-R" option to the builtin ls. This is disabled by # default to avoid remote users being able to cause excessive I/O on large # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume # the presence of the "-R" option, so there is a strong case for enabling it. ls_recurse_enable=YES pam_service_name=vsftp userlist_enable=YES #enable for standalone mode listen=YES tcp_wrappers=YES User authentication is against an ldap server. That seems to be working fine. AFP users can connect ok. I read about an issue with the pam module, but that doesnt seem to be the case. I keep beating this thing around and around with no joy so far. -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools

Kernel numbers
by Jeff Stevens 22 Jun '08

22 Jun '08

What does it mean to see an rpm with a kernel of 2.6.10-1.741_FC3, when we go to a site like http://www.kernel.org and see the latest kernel is at 2.6.10? If one wanted to compile their own kernel from this site, would they be losing fixes/etc. from the "-1.741_FC3" portion? Thanks, still learning here... -- Jeffrey Stevens gpg --keyserver pgp.mit.edu --recv-keys D2E5A4E8 Key fingerprint: 1C86 8717 E485 FA4D B9EF 96E2 A1AC 4B00 D2E5 A4E8

Hi all, I 'm just install a scsi card BusLogic BT-958 and HP DAT 40, on my fedora core 6 system. I usually backup my system, using tar. My problem is backup doesn't running well. And this is my backup script: #tar -b 1024 -cvf /dev/st0 /usr/local/src/my_home/yahoomail | bzip2 -9 > /var/log/Backup.log.bz2 Backup only run a while, and archive some files in directory and then stop.

Re: printer problem fixed -- but why?
by Andrew Couture 27 Mar '08

27 Mar '08

Do you have 'cups' installed? Why not use 'http://localhost:631/', it works well. If you printer doesn't have a driver there, try the 'gutenprint-' package. It is not a *rpm yet, but the instructions are straight forward. andy
