Debian :: File Sharing Via Mapped Directory ?
Dec 13, 2010My friends and I want to have a central server where we can share our files. I would like it to be accessible to each client (friend) by simply logging onto their VPN client and have the shared directory appear on their "My Computer" as a hard drive. It will be a Debian Lenny server that is accessed by Windows computers, and they'll be able to read and write whatever they like.
We do this same thing at work, but I don't know where to start. To access the file server at work from home, I just run our VPN client and I have access to all the drives I do at work. This is exactly what I'd like to do, but at my place. I'd like to know what applications I need to get to make this realizable, like if I need to use Apache, Samba, OpenVPN, etc. I can learn fast, I just need direction.
Eventually I want to evolve this project into something more, but I figured this would be a good starting point in learning server applications.
General :: Ubuntu - Find The Device Node File For USB Device?
Aug 23, 2011I've bought an X10 Home Automation USB interface: the CM15.
This is the information lsusb gives:

But this tells me nothing about where the device file is! How can I find that, or create one myself?

Sep 8, 2010Everything in Linux is a file, right? And everything can be represented by a file? Is there some way I could create a block device file that represents (i.e., provides an interface to) this image file? If so, then I could use fdisk on the device file to split it into partitions, format the partitions, and then mount them as directories. I could create a file system within a file system, which would be fun.

Oct 1, 2010Device/Special file Clairification Requested.I'm reading a short article on Device/special files because it is related to VFS. This article has this paragraph that has to many pronouns in it to get an understanding of. URL..."In short, a device file (also called as a special file) is an interface for a device driver that appears in a file system as if it were an ordinary file. This allows software to interact with the device driver using standard input/output system calls, which simplifies many tasks."
What does a Device file have to do with the Application and the Driver communicating? Wouldn't the order of data transfer be , Application to driver and then to Device file?

View 2 Replies View RelatedGeneral :: How To Find The /dev/Device Mapping For NFS File System In RHEL
Jun 19, 2010Found the below from RedHat Knowledgebase
The Completely Fair Queuing (cfq) scheduler in Red Hat Enterprise Linux 5appears to have worse I/O read performance than in version 4. It appears as though the Completely Fair Queuing I/O scheduler (cfq) has a regression and thus exhibits reduced read-side throughput which can affect performance for both local and NFS mounted file systems.
One way to mitigate this is to set the cfq's slice_idle parameter to zero. To change this value, execute the following command echo 0 > slice_idle in the /sys/block directory appropriate for your situation, as shown below:
echo 0 > /sys/block/hda/queue/iosched/slice_idle
We are using NFS file systems in RHEL 5.3. I would like to know how to find which /dev/Device is being used by the NFS file systems, so that I could try setting the slice_idle to '0' to see if there is any difference in performance? In /etc/fstab I only see the actual NAS volumes for the NFS file systems.
Ubuntu :: Two Keys Mapped As The Same Thing?
Jun 26, 2011After pissing around with Kubuntu all evening, I wish I had hair to pull out in screaming frustration. After trying everything from Xbindkeys to animal sacrifices and voodoo spells to get my multimedia keys working, I now find that both the Windows key and the End key are mapped as F14. Problem is that it's the End key opening the K Menu, not the Windows key.
How can two keys get mapped as the same thing?! And how do I get the End key back to just the End key? I'm close to calling it quits on Linux and putting Windows back on my laptop.

View 1 Replies View RelatedUbuntu Servers :: Nfs4 - Idmapper / Some Uids Are Not Mapped To Names?
Oct 5, 2010i set up a ubuntu server (10.04) with LDAP, Kerberos and NFS4. Did a set up for a client (ubuntu desktop 10.04 32 / 64) to connect to ldap, kerberos and nfs4-mount. All is working fine except of the idmapping. Some uids are not mapped to names. the entrys, which cannot be mapped, change. so 10 minutes before the uid was mapped to the correct name, after that time (i'm not sure if it's exactly 10 minutes) the name is mapped to nobody. sometimes the gid cannot be mapped too.I mount the nfs-share via nfs4 with sec=krb5 (krb5i or krb5p result in the same problem) and after successfully mounting the device, i type ls -la. i never have problems with getent passwd or with logging in as ldap-user. i get all the entries of the ldap-db and i also get kerberos tickets. All is working fine with nfs3, but i would like to use nfs4 for security-reasons.
if i run the rpc.idmapd with many "-v" i get the following messages in the daemon.log-file:
Code:
....
rpc.idmapd[15953]: nfs4_name_to_uid: calling nsswitch->name_to_uid
rpc.idmapd[15953]: nss_getpwnam: name 'test@DOMAIN.TEST' domain 'DOMAIN.TEST': resulting localname 'test'
rpc.idmapd[15953]: nfs4_name_to_uid: nsswitch->name_to_uid returned 0
code....
the first part is the response to a correct name-to-uid-mapping the second part is a failed one. both user exist, both users have the same ldap-entries (except of the different descriptions, uid and so on). the responses have the same timestamp, so the reply is in (nearly) the same second.
restarting the idmap-daemon every 5 minutes or other workarounds are not practicable in normal operating environment.
Server :: ISCSI Failing At Reboot To Detect Mapped Volume
Sep 28, 2010I am trying to connect the one of server RHEL5.4 to the IBM iSCSI storage. Server is equipped with 2 single port Qlogic iSCSI HBA(TOE). RHEL detected the HBA and installed driver itself (qla3XXX). I have configured the HBA ip address in the range of iSCSI host port of storage. Both of the HBA is connecting to the two different controller of storage. I have discovered the storage using command iscsiadm -m discovery command for both of the controller and it went through fine. But problem is whenever server is restarting if both of the hba is connected to the storage then server will not detect the volumes which is mapped to the server and then to detect the volume I need to run "mppBusRescan" and "vgscan" command each time. If only one path is connected it is fine.
View 1 Replies View RelatedServer :: Mapped Network Drive Requires Password After Logging Out?
Jun 14, 2010I have a peer-to-peer network with 25 WinXP Pro computers. I have built a Linux (SuSE) server for the purpose of backing up My Documents, PST files and favourites. Each user has their own folder containing the sync'd files. Each folder is password protected. I have configured each users machine with a mapped 'S' drive, which is the sync'd data folder on the Linux computer. All of the computers seem to end up with a "disconnected network drive" status after either logging out for the day or after some time has elapsed. Some will connect with a double click but others prompt for a password. I have tried mapping the drive using the option "Connect using a different user name", which is fine until the user logs out and back in again. I use SyncToy as a scheduled task, but can't connect to these mapped drives automatically, so the sync process will not work unattended.

OpenSUSE Install :: Can't Edit Back Device.map File
Dec 23, 2010I've got myself in a bit of a pickle.I've got 1 hard disk drive and was trying to load a second external drive.I tried to mount the 2nd (external) drive by editing /boot/ grub/ device.map but I must have made an error, because now it boots directly into sda1 openSUSE 11.1 and when I try to look at SDA2/SDA3 it say's Invalid System Type. Presumably because they're formatted with Ext4. So I can't edit back my device.map file.What I want to do is boot into SDA3 OpenSUSE 11.3. Would anybody know why it's only booting to SDA1 and/or have any suggestions to get me back booting to SDA3? This may be a 2 step process, because I may have to boot to SDA2 first so I can edit back my /boot/grub/device.map on SDA3 before finally booting to SDA3.
