Networked hard drive
by Anne Wilson 26 Oct '07

26 Oct '07

I've bought a drive with usb and network connection. I used the usb to quickly transfer a large quantity of data, but intended putting it onto the network after that. The blurb on the box said it would just pick an ip by dhcp. However, it seems to me that I need to know something about it in order to mount it, and I've got a total blank on where to go next. Nothing appears in /var/log/messages. I've told the router to reserve an address for it and made an entry in /etc/hosts. Since I can't see any sign of it being recognised I haven't a clue how to mount it. Any ideas? Anne

Kernel 2.6.22.1-27.fc7 breaks NFS
by Miner, Jonathan W (US SSA) 17 Oct '07

17 Oct '07

Hi - Just upgraded from 2.6.21-1.3228.fc7, and now seeing problems with NFS. I originally believed the problem was with the automounter, but it looks like it might be NFS instead. Rebooting with the old kernel solves the problem. In this example, I'll create a new mountpoint, and try to mount my home directory. The directory is being served from a SUN Cluster 2.1 server. # rm -rf /h # mkdir -p /h/jminer # mount superfly:/superfly/vol02/home/jminer /h/jminer mount.nfs: /h/jminer is already mounted or busy # echo $? 32 Now, if I try to mount the directory from the physical node, the mount suceeds. # mount fly_a:/superfly/vol02/home/jminer /h/jminer # echo $? 0 I saw similar problems with an earlier FC release, but it was related to either the autofs or nfs-utils package.

Upgraded to fc7, but sendmail submission with TLS no longer works
by Philip Prindeville 17 Oct '07

17 Oct '07

I'm running fc7 (updated). I updated via yum from fc6. Oddly, Cyrus continued to work after the upgrade (it usually breaks). This time it was sendmail that broke, even though I'm running with a fairly stock system. The extent of my sendmail.mc edits are below. I get messages from sendmail saying that my client (Thunderbird on Windows Vista and FC7), well: Sep 29 19:21:59 mail sendmail[5288]: STARTTLS=server, relay=pvr.redfish-solutions.com [192.168.1.8], version=TLSv1/SSLv3, verify=NO, cipher=DHE-RSA-AES256-SHA, bits=256/256 Sep 29 19:22:23 mail sendmail[5288]: l8U1LxLB005288: pvr.redfish-solutions.com [192.168.1.8]: possible SMTP attack: command=AUTH, count=4 Sep 29 19:22:30 mail sendmail[5288]: l8U1LxLB005288: pvr.redfish-solutions.com [192.168.1.8] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA-v4 Sep 29 19:23:05 mail sendmail[5295]: STARTTLS=server, relay=pvr.redfish-solutions.com [192.168.1.8], version=TLSv1/SSLv3, verify=NO, cipher=DHE-RSA-AES256-SHA, bits=256/256 but if I turn off TLS, it seems to work ok (using username/password authentication in the clear, I guess). Since it's TLS, I couldn't use tcpdump to read the transactions... Here are the sendmail.mc edits.

FC6 Issue with Cups after update
by Wade Hampton 14 Oct '07

14 Oct '07

I just did a yum update on my son's computer. Now the cups daemon won't start. Running /sbin/service cups start results in: Unable to read configuration file '/etc/cups/cupsd.conf' - exiting! I checked the permissions and they are root, lp 644. If I run the same code as in the /etc/init.d/cups script, it starts and works fine: su . /etc/init.d/functions DAEMON=cupsd prog=cups echo -n $"Starting $prog: " daemon $DAEMON RETVAL=$? [ $RETVAL = 0 ] && touch /var/lock/subsys/cups Using su, I tested and user lp can read the cupsd.conf file. Any ideas? -- Wade Hampton

strange ssh performance issues
by Kevin Kempter 12 Oct '07

12 Oct '07

Hi List; First let me say that (1) I have a fairly unusual (I suspect) ssh setup, and (2) I hate the virus known as windows Here's the deal; The client I'm working for uses a SonicWall firewall to control access to the data centers. Unfortunately there are issues with the Linux openVPN clients (specifically open swan) where it connects but locks all other connections out of the firewall. So, until we figure this out the solution is to use the windows version of the SonicWall client. I've installed vmware and installed a copy of VirusXP (AKA Windows XP). I installed cygwin and followed the instructions here to install the ssh server: ( http://pigtail.net/LRP/printsrv/cygwin-sshd.html ) although I did not run the mkpasswd and mkgroup commands, they seemed to break the install of ssh server. Anyway, I also setup an ssh key so I could login to the M of VirusXP without a password. Next I setup a config file in my Linux $HOME/.ssh dir with many entries like this (one for each host in the data ceners that I need to connect to): Host dataCenterHostname Hostname 10.1.x.x # data center I.P. HostKeyAlias 10.1.x.x # data center I.P. ProxyCommand /usr/local/bin/netcat-proxy-command 172.16.128.128 %h The 172.16.128.128 I.P. addr is the I.P. of the VirusXP image within vmware via nat. (I could not make the ssh connections work via bridged networking). The /usr/local/bin/netcat-proxy-command script is a netcat (nc) script and contains this: #!/bin/sh gateway=$1 internal=$2 ssh $gateway nc -w 1 $internal 22 To use this setup I boot up VirusXP, open the SonicWall VPN client and connect to one or more of the data centers. Then in Fedora 7 (the host OS) I open a terminal and run this: ssh dataCenterHostname so, to my issue. Most of the time this setup works fairly well, in that it does connect. It usually takes about 30 seconds for me to get a password prompt for the target data center host. This is acceptable but I think there's something weird going on that delay's the connection. I say this because I can open a cygwin windowin VirusXP and do an ssh <I.P.> and I get a password prompt immediately. The main issue is that several times a day the connections start to take several minutes to return the password prompt. I need to restart the cygwin service in VirusXP, and sometimes that doesn't help so I reboot the VM instance of VirusXP. This is quite frustrating, however I'm a DBA and have limited networking knowledge. Does anyone have any thoughts?, suggestions?, comments? Thanks in advance..

Help: very slow software RAID 5.
by Dean S. Messing 12 Oct '07

12 Oct '07

I'm not getting nearly the read speed I expected from a newly defined software RAID 5 array across three disk partitions (on the 3 drives, of course!). Would someone kindly point me straight? After defining the RAID 5 I did `hdparm -t /dev/md0' and got the abysmal read speed of ~65MB/sec. The individual device speeds are ~55, ~71, and ~75 MB/sec. Shouldn't this array be running (at the slowest) at about 55+71 = 126 MB/sec? I defined a RAID0 on the ~55 and ~71 partitions and got about 128 MB/sec. Shouldn't adding a 3rd (faster!) drive into the array make the RAID 5 speed at least this fast? Here are the details of my setup: # fdisk -l /dev/sda Disk /dev/sda: 160.0 GB, 160000000000 bytes 255 heads, 63 sectors/track, 19452 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 127 1020096 82 Linux swap / Solaris /dev/sda2 * 128 143 128520 83 Linux /dev/sda3 144 19452 155099542+ fd Linux raid autodetect # fdisk -l /dev/sdb Disk /dev/sdb: 160.0 GB, 160000000000 bytes 255 heads, 63 sectors/track, 19452 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 1 127 1020096 82 Linux swap / Solaris /dev/sdb2 128 143 128520 83 Linux /dev/sdb3 144 19452 155099542+ fd Linux raid autodetect # fdisk -l /dev/sdc Disk /dev/sdc: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdc1 * 1 127 1020096 82 Linux swap / Solaris /dev/sdc2 128 19436 155099542+ fd Linux raid autodetect /dev/sdc3 19437 60801 332264362+ 8e Linux LVM The RAID 5 consists of sda3, sdb3, and sdc2. These partitions have these individual read speeds: # hdparm -t /dev/sda3 /dev/sdb3 /dev/sdc2 /dev/sda3: Timing buffered disk reads: 168 MB in 3.03 seconds = 55.39 MB/sec /dev/sdb3: Timing buffered disk reads: 216 MB in 3.03 seconds = 71.35 MB/sec /dev/sdc2: Timing buffered disk reads: 228 MB in 3.02 seconds = 75.49 MB/sec After defining RAID 5 with: mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sda3 /dev/sdb3 /dev/sdc2 and waiting the 50 minutes for /proc/mdstat to show it was finished, I did `hdparm -t /dev/md0' and got ~65MB/sec.

Gnome panel lost most icons...AGAIN
by Frode Petersen 07 Oct '07

07 Oct '07

This is a recurring problem, but the intervals are relatively long. This time it's about a month since the last time I experienced it. Sometimes it takes longer for it to show up again. I use a single panel on the right side of the screen, have applets, icons and drawers on it. This time I removed the Tomboy icon from the panel. An error message appeared telling me that there was some error with the configuration files, and that the panel may not display correctly. Most of the icons disappeared, including all drawers. In gnome-config section /apps/panel/toplevels all entries for the drawers are still present, but in section /apps/panel/objects they are gone. I've found bug reports about something similar, so I'll try and see if it helps to go that route, though it seems to be an old problem. My question here is: Is there a way that I can make a backup of the working setup and bring it back if this happens again? Frode Petersen List of objects involved (I don't know if this helps any, but..) The objects that remained were: clock, workspace switcher, PanelFM, Window list, Notification area, NetworkManager icon, System monitor CPU frequency monitor and volume control. The ones that disappeared were: Main menu, 8 drawers with quite a few icons in them, terminal, lock screen.

Formatting CDs
by Aaron Konstam 07 Oct '07

07 Oct '07

It has been stated that you can format CD-RW using cdrecord or k3b. I can't find that option in either program. k3b can format DVD-RW and DVD+RW but not CDs as far as I can see. Could someone explain how to do it -- ======================================================================= If you're crossing the nation in a covered wagon, it's better to have four strong oxen than 100 chickens.

Internet traffic and Azureus -
by Bob Goodwin 04 Oct '07

04 Oct '07

Can someone tell me hos Azureus on a Windows computer on my LAN might affect the amount of data downloaded via my ISP? My son-in-law finally admitted that his son had installed Azureus on his computer while visiting a couple weeks ago. WE have a limited amount of data allowed by Wildblue, 17 gigs in a 30 day period and it is becoming a panic situation with less than 2 gigs before we hit the limit and they take action! Can Azureus be the cause of the excessive traffic or am I looking in the wrong place. I closed the bittorrent port in the router months ago and that should still be closed ... Presently we have his computer shut down. There's no telling what he's got on it but my daughter is threatening to put him back on dial-up! I can see a period of strife on the horizon.
