I plan to:
- replace my hard drive with a 32GB SSD (solid state drive) SATA-II
- copy my entire old drive to the new one
- Both my drives will be Ext3 and have no swap (I have lots of RAM)
1. Can a Debian lenny desktop boot from an SSD ?
2. Do I have to modify /etc/fstab with SSD-specific options ?
3. How about grub, any modifications ?
I used the usual 'mkfs.xfs -l size=128m,lazy-count=1 /dev/sdX' at creation. After that, I would like to use custom mount options like: This goes instead of the "defaults" part in /etc/fstab
noatime,nobarrier,logbsize=256k,logbufs=8,biosize=16
I receive the following error at boot: INVALID log iosize 4 [not 12-30] << No one used iosize 4... what does it mean? it is connected to the options..but which one? (At the minute I'm usig it with: noatime,nobarrier).
I know if I run repquota -a I can see the quotas set for all users.How do I modify the quota for a specific user?So say the output for john is:User used soft hard grace used soft hard grace----------------------------------------------------------------------john.someth -- 122844 51200 51200 4995 0 0How do I make his block limits 0 so they are unlimited?

I reinstalled grub with suse dvd and it went ok. Pc working properly. But then i tried to fix this once for all and changed the fstab options from /dev-by-id to uuid (all partitions : swap, /, /home etc ).Is uuid a definite solution ?Why is the pc not able to start from there ?
Since i moved the partitions with uuid option in fstab and even after reinstalling grub the pc is not starting anymore . It gives me the boot menu (linux suse/failsafe) and then a black screen left with no keyboard nor mouse available.

I know that 'man gfortran' will get me the manual page for gfortran, but how do I lookup only the bit I want, which is '-Wall'? I can't find anything in the manual page for man.I could use 'man gfortran | grep -Wall' but that would return just a single line and not the whole paragraph.

I have a specific NTFS partition on a USB drive that I wish to enable execute support for. The only way I've found to do this is to add the partition in /etc/fstab with a umask. This poses some problems:
1. Only root can mount it, making it a pain to mount (open terminal, `sudo mount (path from /etc/fstab)`, enter password, close terminal).
2. The system will hang at start if the UUID is unavailable (or, the external disk is unplugged). I run several servers from my machine, so if I do a remote restart it will not come back up because of the hang.
Is there a way to specify to FUSE (which I believe is the handler for auto-mounting in Nautilus) that this partition should have execute access to files?
What would be the best way list disk and partitions in the fstab file?
View 1 Replies View RelatedI've had two hd's in my box forever. for more space and backup reasons. Well I have started running the Debian Squeeze distro since December. I've had many issues, some are still unresolved. but now I'm running into major headaches with the fstab. Specifically dealing with/wondering why UUID's are used instead of the old /dev/hd? I was a little annoyed when I tried Kubuntu to find /dev/sd? used instead of /dev/hd? but that was workable. But the UUID's are a nightmare. Here's my problem.
My main box is finally giving up the ghost. The mobo is dying. So in order to do some tests I took my hd bundle (my two hard drives with their cables) physically out of the box and temp installed them in a test box. I wanted to do some benchmark and other tests. I got all kinds of errors. I found that the system wasn't recognizing the UUID's listed in fstab. My concern is when the new mobo gets here next week I won't simply be able to plug the hd's in like I always have been and just let Linux reconfigure itself (Debian used to be good about this). I really don't want to have to clean reinstall if it's not needed.
So for this I have two questions. WHY developers decided to drop using /dev/hd? or even /dev/sd? ?
And is it possible to revert fstab's listings back to the old /dev/hd? settings. In debian fstab had lines commented out showing how each partition was listed in it's /dev/hd? status during install.
I'm getting really sick of all these archane changes in ALL aspects of linux that don't seem to have any good explaination or need.
how modify the file grub.cfg?, is for 6.0, the grub2.

(Bios priority boot sata) first, I've installed Seven on the hdd ide and diconnected it. Second, I've installed Sid under hdd sata. So after, sda is SID (sata) and sdb is Seven (ide). Since I've reconnected ide hdd, as say above, my partitions switch alternatly from sda to sdb and vice versa. I use Grub2 and UUID, there no move inside these files Is there another file to configure to avoid this?

Trying to read the fstab file using code...
So why can't I read the fstab file?
I am running Debian Squeeze, 64-bit.I would like to try my hand at bash scripting. So at the author's suggestion (first chapter of Chris F. A. Johnson, Pro Bash Scripting from apress) I created a /bin directory in my home directory. So now I would like to modify my PATH statement so that when I run a script from my bin directory my shell will find it.I did that. He then says that I should add this to ".bash_profile, .bashrc, or .profile depending on how bash is invoked." The find command is unable to locate any of these files. So I searched the forum, found the link above and tried to follow that. No luck so I assume that how Debian handles PATH statements has changed since that post?
I also have checked the wiki and worked Google as hard as I know how to do.Very simply where the heck is my PATH statement and how do I modify it?
There are some sites who are for example U.S.-only...Using Windows and Firefox, it often helped to just install Modify Headers, set it up correctly and you're done (it changes your ip-address you show to a website) Using a proxy really slows your connection down, but the app didn't.Is there an app for Iceweasel pretty the same, or at least one being able to do the same?

I know that in FreeBSD it is possible to use ipfw for that purpose, because it build-in into kernel. We set for example rule Code: Select allipfw add divert 2000 ip from any to 1.0.1.1
and we can use our own application to process those packets, reinject them forward etc. It will work also fast, because as I said, it build into kernel.
Is there any standart Linux-based solution to do the same? I found some info about netmap-ipfw. Is this a correct solution? Or I have to use for example IP-aliases and iptables to do that?
I need to process all the IP-packets, not only TCP/UDP/etc-protocol. Solution also must be very fast.

View 2 Replies View RelatedI used a clonezilla live cd to clone a working updated install to another SSD of the exact make and model. Something went terribly wrong, and the new system booted to emergency mode. I then went back to my working laptop I cloned from and it did the exact same thing when booted, into emergency mode. After a couple of days trying to figure out how to rebuild the FSTAB on the once working machine, I finally figured out how to mount the root partition and copied all my important stuff off. WHEW!
Before I was able to mount the root partition, I had a heck of a time trying to mount it, getting errors about unable to read superblock, etc. I used testdisk that I installed on a debian live cd (on a flash drive) and it did something, not sure, but after that, and rebooting, I no longer had sda1,sda2, and sda5. I only had 1 and 5. sda2 was the root partition (extended, ext2) and I thought all was lost. But after running fdisk -l, I noticed two other devices... dm-0 and dm-1. I noticed that dm-0 was my root partition and read that it has something to do with LVM. I mounted it, and grabbed all my important stuff.
Now I am stuck at rebuilding my fstab so my boot, root, and swap partitions are properly mounted. Again, I do not have anything to copy and paste yet. I guess I got lazy since a lot of my work on this system is via Putty and SSH from a windows machine. It certainly looks like the partitions are there and ok, just not sure where to go from here.
I read that I need to get the UUID's from the partitions, then rebuild the fstab using those. I figured out pretty quickly that using /dev/sda1, 2, and 5 did not work. And the UUID's are pretty long. Without copy and paste, I am not sure how to use those without manually keying them in. I tried shelling into my laptop via putty while it is in emergency mode but failed.
Using: Debian Lenny. I want to mount 2 NTFS partitions in my /etc/fstab file, so that I needn't manually mount them when I want to use them. One of the partitions is the primary partition on the same hard disk as my Debian /, /home, and /swap partitions. The other is a 2nd internal hard disk.
a) Should I use ntfs-3g instead of ntfs as the /etc/fstab filesystem? I want to be able to read and write to the partitions as a user and not just as root.
b) I have read on the forum that "mounting NTFS partitions through fstab is not a great idea" - I thought that any dangers of doing so were ancient history. Why would it not be a good idea?
c) Which options should I use?
d) If I use 'user' instead of 'users' so that one specific user (me) can use the partitions, how do I specify which user name? (The man page is annoyingly unclear about this).
I've apparently changed my fstab file and now my boot drive fails to mount. The original file is still there "fstab.BAK". How do I rename the current fstab to another name and rename the fstab.BAK to fstab? Since this is read only in the /etc directory I have not been able to make this happen from a command prompt.

View 2 Replies View RelatedI currently run openVPN on my Debian box that provides secure ipv4 routing from my laptop to my VPS in a different country (and from there the internet via this box). This works fine. However, id like to sort out ipv6 through this VPN as well as IPV4 and not overly sure how to do it. The remote server itself has native ipv6 configured on device eth0 and it works (ping6, traceroutes all fine,incoming to web servers etc) nicely on dual stack.
How would i go about modifying the config (both client and server if needed) to enable openVPN to act as a tunnel broker to enable the laptop to use the ipv6 through the server as well as the old v4? (the internet connection laptop end will not/does not have native ipv6 from the ISP. Currently im using he-net tunnel broker but id like to run myself through my existing openVPN). VPN config details: Its using UDP, port 1194, creates a TUN interface, redirect-gateway etc and the rest is normal config. Edit:- if it matters the clients are all running windows so i cant use sh scripts to set up stuff client end.
Before I leave with a bad taste in my mouth forever from the linux communities here, I'd like to ask one more question. I've been snooping around a bit about this issue of how to automount USB Drives, have them show on the desktop in file managers like PCManFM and not have to touch fstab at all.
How do I do this? Without touching Fstab, GNOME, any other DE. I only want openbox around.Another question I also hope to answer: How do I make shortcuts in PCManFM?
I've accidentaly corrupted my fstab and cut the ends of lines. There are now disk uid, mount point, filesystem for root and swap, but the mount parameters are missing.The system boots as readonly. What are default fstab mount parameters in Debian for ext4 root and swap?
