Red Hat :: Wrong Entries In FSTAB?
Jul 15, 2010
I decided to implement quota on /home file system, but unfortunately I had not separate partition of /home file system. So I made entries in fstab at root (/) partition as follow:-
Label=/ / ext3 defaults,usrquota, usrgroup 1 1
and reboot the system, but my system could not give me login screen and after a longtime giving many "read only files" error ends up at following error message:-
"I could not start the X server (your graphical environment) due to some internal error. Please contact your system administrator or check your syslog to diagnose. In the meantime this display will be disabled. Please restart gdm when the problem is corrected."
I also got single user mode and try to remove changes whatever i had made recently but it gives me read only fstab file.

I have UUID entries for USB devices in fstab in my Ubuntu 10.10. I assume this is because I have upgraded my Ubuntu's since 8.04. Each time I boot, I get a message saying it cannot mount the devices even though they are present. I have to skip mounting in order to complete the boot process. I also have two filesystems mounted at Root ( /). See later post in this thread.can I safely remove these entries from fstab and have Ubuntu automount the devices? If I do so, will this get rid of the messages at boot time?

I added an sshfs entry fto /etc/fstab in a fresh FC15 build ona laptop and this seems to work
sshfs#user@server:/opt/apache-tomcat-7.0.2/webapps/ /mnt/server/opt/apache-tomcat-7.0.2/webapps/ fuse uid=500,gid=500,allow_other 0 0
I can mount and umount /mnt/server/opt/apache-tomcat-7.0.2/webapps/ without problems.
But after a reboot the systme it hangs when loading, I can't copy paste the messages but it said something about boot dependencies, and it was apparent the error was loading fstab. I had to Ctrl D or enter root password to get a recovery system, after commenting out the sshfs line (and some nfs lines too) from /etc/fstab after another reboot I was in.
sshfs used to be permitted in /etc/fstab it seems , I've not used it before, could this be a FC15 issue? I have seen other threads about FC15 and nfs boot issues presumably to do with the new booting mechanism.

After installing 11.4 my fstab entries for CD and DVD drives as well as floppy generate errors when I try to mount them automatically or via Nautilus when inserting CD or DVD. The icons and CD/DVD name show up ok but will not mount. Manually mounting via terminal command works. Here are the relevant lines from fstab
[Code]...
In /dev scd0 and scd1 are symlinks pointing to sr0 and sr1 respectively. The above error message was generated after attempting to load a CD in scd0 i.e. my laptop internal CD/DVD drive. Lines 10,11 and 12 are the fstab lines quoted above.

Recently installed Centos 5.6 in order to install Plesk on. Not familiar with Linux partitioning so left the default values at install with a few GB of unpartitioned space left free. Followed the instructions on the Plesk installation manual for adding a seperate partition for /tmp - [url]
Then later on I couldn't get in to the server locally via the GUI (which was already switched on), it just had a black screen so I powered the machine off. It then wouldn't boot back up. When it got to e2fsck I got a [Failed]. I also got the same message as in this thread.
I'm now at a remote location. When logging in as root and trying to run fsck to find and fix any disk problems a remote engineer has found that it won't unmount the partitions so I can't really run fsck on it. He's forced the machine to boot for me and I have SSH access but if I reboot the machine I'm quite sure I won't be able to get in again from here.
Is there something wrong with my fstab maybe?

I'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.

I am working on Red Hat Linux since last six months and learning it steps by steps. like configurating ftp server,NSF ,DNS and then email server. I want to learn squid server but technically before going into it what you suggest me that may I first learn to configure Linux as a router,Firewall machine or do IP masquerading on a server. Because all these things are directly or indirectly involve in squid.So guide me because going to start squid i may understand Linux IP table ,how to add entries in it,how to delete entries ,I think you understand my point which i want to ask for guidence.

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.

So I have some entries like the ones below. I have a system setup to do all the routing/dhcp/dns. This is a private network for education purposes only, and I have no idea how half of these addresses got in the arp table.
shell>arp -n
192.58.128.30 (incomplete) eth0
192.228.79.201 (incomplete) eth0
192.36.148.17 (incomplete) eth0
[Code].....
how to just clear the table. That's all I want. Is that too much to ask? I also noticed in Wireshark that packets are constantly being sent to find the MAC address that these IPs belong too. I really want that to stop happening.
EDIT: I have also tried using ip neighbor. I ran "ip neighbor del 192.58.128.30 dev eth0", and it gave no errors but didn't remove the entry. All the ones without a MAC are also listed as FAILED in ip neighbor.

Is there a way to know the dns entries of a certain domain? Let's say I want to know its IN A records on their DNS Server. I know you can find the MX Record using the host command but I want to know the other IN A records associated with the specific domain.

I am not referring to the bash history file. I am referring to the system log file. All of my console activity (letter for letter) is being stored in the system log. It's my understanding that version 4.1 of bash is where this behavior first started but was originally optional. I don't like it and I want to stop it. I am using a current version of jessie with bash 4.3 and I can find no way of turning it off
Monitoring the activities of users may be necessary .for admins in a business environment but this is a home computer and I consider this kind of tracking intrusive and unwanted.
I first noticed this with the journal system log and mistakenly though it had to do with journal so I removed the journal system and installed dsyslog which has the same behavior.
Perhaps debian should offer two versions of bash. It's my understanding that this is configured in a header before compiling.

I'm using Ubuntu 9.10 (karmic). And, my ~/.pam_environment looks like the following.
PATH DEFAULT=${PATH}:~/Adobe/Reader9/bin:~/texlive/2009/bin/x86_64-linux
GIT_EDITOR DEFAULT=vim
MANPATH DEFAULT=${MANPATH}:~/texlive/2009/texmf/doc/man
INFOPATH DEFAULT=${INFOPATH}:~/texlive/2009/texmf/doc/info
But, echo $PATH returns me duplicated entries as the following.
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:~/Adobe/Reader9/bin:~/texlive/2009/bin/x86_64-linux:~/Adobe/Reader9/bin:~/texlive/2009/bin/x86_64-linux
I've tried replacing DEFAULT by OVERRIDE in my ~/.pam_environment file. But, that didn't help.

I'm running OS X and it appears that after SSHing to several machines, using identity files, my ssh-agent builds up a lot of identity / keys and then offers too many sometimes to a remote machines, causing them to kick me off before connecting.
Received disconnect from 10.12.10.16: 2: Too many authentication failures for cwd
It's pretty obvious what's happening, and this page talks about it in more detail:
SSH servers only allow you to attempt to authenticate a certain number of times. Each failed password attempt, each failed pubkey/identity that is offered, etc, take up one of these attempts. If you have a lot of SSH keys in your agent, you may find that an SSH server may kick you out before allowing you to attempt password authentication at all. If this is the case, there are a few different workarounds.
Rebooting clears the agent and then everything works OK again. I can also add this line to my .ssh/config file to force it to use password authentication:
PreferredAuthentications keyboard-interactive,password
Anyhow, I saw the note on the page I referenced talking about deleting keys from the agent, but I'm not sure if that applies on a mac since they appear to be cleared after reboot anyhow. So, my question is, is there a simple way to clear out all keys in the ssh-agent (the same thing that happens at reboot)?

I used Ubuntu a few years back. I simply was not able to make it my main OS since I couldn't get video calling to work reliably enough. Anyways I just installed and noticed my grub menu had many more entries then I have operating systems on my computer. Some reason they came up as duplicates. I have so far gathered they took away my menu.lst, they replaced it with something like etc/general/grub. It appears editing this file doesn't give me the ability to change entries. There are a few I would like to rename, and a few I want to get rid of. There is also some other file that is not supposed to be edited, will I need to edit this or is there another way around it? I found info like this, but it is only adding not removing.
Assuming that you already looked at the grub2 documentation and had trouble figuring out what to do, try this. Use sudo to edit /etc/grub.d/40_custom. It will look like this:
Code:
#!/bin/sh
exec tail -n +3 $0 .....
After making the change, run 'sudo update-grub' to apply the change to your grub config.
TLDR: Grub 2 added extra entries, how do I remove and rename some?

I have a dual-boot grub2. On the list, there are Ubuntu 10.04, Memtest x86, and Windows7. I was wondering if it is possible to make Windows 7 first in the grub boot list. At the moment Ubuntu is first, so if it's possible to make windows 7 first.
