Problem with gnome, Fedora core 3

by Ken Jones

Gentlemen and ladies, My Fedora Core 3 - which has been yum'd up to date - behaves strangely when using GNOME as the windows manager. The right click on blank desktop space does not work. The right click on a panel to make a new panel does not work. The result is that I can not set up any launching icons on my desktop. There is no unused space on my one (bottom) panel. The panel-disappear icon is missing. Any ideas what controls this behavior and ow I can fix it? On a different machine I have a Core4 system running GNOME perfectly. Ken Jones

The messages above and the output of the grub "geometry (hd0)" command, assuming everything is on the first HDD in the system. Also let us know the intended mount point for each of those partitions. Andy is correct in that the best way to figure this out is to work with the grub command line and walk through the steps it would take trying to boot your system. And Eric is correct in that the grub config file would also be handy. Since the disks are partitioned the same my guess is that the problem lies in the grub stage image installation. I believe some filesystems can get away without a stage1_5 (ext2 being one example, likely used on your RH box) and since you didn't supply an explicit image device to the setup command it's possible that the install wasn't able to find them on the root (hd0,0) that you specified. > Is there a better way to clone Linux drive -> Linux drive? Yes, boot from a Linux CD (like the knoppix that you mentioned) and `dd if=/dev/<good> of=/dev/<blank>` <good> might be hda for example. Obviously blank needs to be as big or bigger than good or you risk an incomplete copy and therefore chopped filesystems. BR

Grub problems after imaging drive

by Dick Goodman

I recently configured a RedHat 9 system with OpenVPN . The original configuration was done on an old junk box. This is a single boot w/grub system As of last week I knew nothing about grub; I now know marginally more. As it was working successfully, it was decided to build a new box for it. The hard drive was imaged with Ghost Corporate 8.x and restored onto the new drive. There are some known issues with 8.x and grub The grub screen comes up on booting the new box, but when selecting the (one) entry for RH9, after a short pause it comes back to the grub screen. I read the grub manual, and from the grub screen did c-command, then root (hd0,0) setup (hd0) quit The messages after setup did not look like error messages. The behavior is the same, although I see a message about stage 1.5 flicker by. I figured out how to look at the hard drive with Knoppix 3.8.2 Live CD and the partitions and contents look "ok", so it appears to just be a boot issue. How do I resolve this? What additional information do you need? Is there a better way to clone Linux drive -> Linux drive? Dick

Re: [Wlug] SSH without passwords

by Chuck Anderson

I usually create service-specific unpriviliged accounts with their own SSH keys with no passphrases for this purpose. If there are many services/users that need to log in between the boxes, and you don't mind the boxes trusting each other completely, you can use HostBasedAuthentication, which is sort of like rhosts, but with SSH Public Key authentication. Then any user can SSH between boxes that are in /etc/ssh/shosts.equiv with no password, and no user-specific key/passphrase required.

Make sure public key auth is enabled on the client and server: /etc/ssh/sshd_config: RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys /etc/ssh/ssh_config: Host * RSAAuthentication yes PubkeyAuthentication yes (these are defaults, and so they are commented out in my files) SSH version 1 uses RSAAuthentication, SSH version 2 uses PubkeyAuthentication. Make sure the perms on the directories and files are tight enough (sshd checks): chmod 700 ~/.ssh chmod 600 ~/.ssh/* Finally, are both the server/client the same implementation of SSH? SSH.COM uses slightly different formats than OpenSSH for the public keys. ssh-keygen can convert between the formats.

A trojaned ssh server could steal your password. Passphrases and private keys are never sent anywhere outside of your box (unless you want them to). If an account password gets compromised, you may have to change it on many boxes, and it may be shared with other unrelated accounts elsewhere. If a passphrase gets compromised, it doesn't allow anyone to do anything without your private key file--you need both the private key and the passphrase. You can share your passphrase for many different private keys, but still have different passwords on unrelated remote systems. You can cache the passphrase in the memory of your local box (ssh-agent) so you don't need to enter anything to ssh to remote boxes. Using a private key with a blank passphrase means someone could steal your private key file and use it to log in as you. This weakens the requirement for having to steal both the private key and the passphrase. Since the private key sits on disk for a long time, someone down the road could steal it and you may never know. This is even worse if you use a network filesystem for your home directory. The passphrase encrypts your private key.

SSH without passwords

by Mike Leo

I remember someone talking about sharing keys between systems so you can ssh around at will without needing the password.... we are trying to do this, but are having a hard time. Anyone have a good doc (or willing to write one) about how to do this? Basically we are ssh-keygen -t (dsa/rsa) the keys, copy them to the "remote" servers ~/.ssh/ There are conflicting doc's at this point...some say you need an ssh-agent, some don't mention it. Some use passphrases, some don't. But if i have to enter an ssh passphrase everytime, why not just use the account password? Any advise would be helpful... thanks as always.. Mike

Re: [Wlug] SAMBA My Documents Redirection and Offile Available with out Roaming Profiles

The redirection part is quite easy, the problem I'm having is making it available offline. This happens automatically in winXP with a roaming profile where all the profile data is offline. This policy can be applied to just the My Documents folder in 2k server and 2k3 server. On 11/28/05, Karl Hiramoto <karl(a)hiramoto.org> wrote: > That is pretty easy to find your self. run regedit.

That is pretty easy to find your self. run regedit. Search for key value of "My Documents" And you will find the value that is by default set to c:/user data/My Documents or something like that. I don't have a Micro$haft machine near me right now, or i would search for the value and tell you. ;-) I just did a quick google search and found some examples: http://www.linbox.com/ucome.rvt/any/doc_distrib/samba-2.0.9/pdc/profiles.ht… http://www.sfu.ca/ad/logon_scripts.html http://www.rethinkit.com/ntscript/LogonScript.htm http://www.experts-exchange.com/Programming/Programming_Platforms/Q_2150380… Matt Higgins wrote: > I have a logon drive of H: where there home dir is shared and mounted > at login.

SAMBA My Documents Redirection and Offile Available with out Roaming Profiles

by Matt Higgins

Here is some back ground before the question: I'm currently running a SAMBA PDC 3.0.10 on FC3. Samba is backed by an LDAP server for account information ldapsam. User accounts were created with smb-ldap tools from IDEALX. I have fixed these scripts up a bit so they also add ldap attributes for OpenExchange. The PDC has a netlogon share with a nice Default Profile for users. Roaming profiles is turned on and all profile data is replicated to the server. All the clients are windows XP Pro. The problem is the profiles are quite large and we don't have the space to support many more users. We also have quite a few remote sites were replicating an entire profile is not practical. I have found that the most important data is in My Documents. Mail is stored on the IMAP server and contact and calendar in OpenExchange. I have read many howtos including nearly the entire Official Samba Howto. All of these documents describe folder redirection with respect to roaming profiles. I have also not found any documents that address the issue of making a redirected folder available off line such as the My Documents folder. I have looked at excluding Folders from the Roaming Profile so only the Personal folder a.k.a My Documents is "roamed" but that looks like a hack. Is it possible to disable roaming profiles and still distribute my nice Default User profile from netlogon? I am fairly sure this is possible just have not tried. Is it possible to disable roaming profiles and then redirect the My Documents folder to a share and make it available off line? This is common behavior for a win2k3 server. Is anyone doing this in production and can give me some pointers or point me to some documentation? Could these settings be made with .pol file or with a bat script running at logon? My I deal scenario is this. User logs in for the 1st time the Default User profile is loaded from the PDC, the My Documents folder is redirected to a share on the server, say there home dir, and that folder is available off line. -Matt
