  • Error "fileid changed" when accessing files over NFS

    - by Roman Prikhodchenko
    I have an nfs-kernel-server configured and running on Ubuntu 10.04 Server. /export THIRD_SERVER_IP(rw,fsid=0,insecure,no_subtree_check,async) SECOND_SERVER_IP(rw,fsid=0,insecure,no_subtree_check,async) /export/ebs THIRD_SERVER_IP(rw,fsid=0,insecure,no_subtree_check,async) SECOND_SERVER_IP(rw,nohide,insecure,no_subtree_check,async) I mounted the exported folder to the second server: mount -t nfs4 -o proto=tcp,port=2049 NFS_SERVER_IP_HERE:/ebs /ebs and it works just fine. I mounted it to the third server but I cannot access files from it. ls -l /ebs ls: reading directory /ebs: Stale NFS file handle total 0 The syslog on the third server says: kernel: [11575.483720] NFS: server NFS_SERVER_IP_HERE error: fileid changed kernel: [11575.483722] fsid 0:14: expected fileid 0x2, got 0x6e001 Some info: uname -r 2.6.32-312-ec2 uname -m i686

  • PHP shell_exec times out, but not when executed manually

    - by Breck Fresen
    I have a Windows 2008 server with PHP and msys installed. I also have a simple php script that calls shell_exec and tars a few files. When I run the script on my development machine (Windows 7), it works fine. However, when I run it on the Windows 2k8 server, it times out. When I copy and paste exactly what's being run on the cmd line and run it, it executes w/out error in less than a second. One more important detail: when I shell_exec 'dir' or 'netstat', the script runs without any problems. When I shell_exec 'ls' it hangs. When I run ls on the command line, it returns immediately. Other details that might be useful: The Windows 2k8 server is a VPS hosted by Rackspace. I did vanilla installs of Apache, PHP, and msys, but I haven't installed anything else. When I run whoami, I see the php script is executing as the user "nt authority\system".

  • Create an alias in Windows XP

    - by Lord Torgamus
    Back in school, I used to have a .login file along the lines of alias ll = ls -l alias dir = ls -Fhl alias web = cd ~/public/public_www/development ... I'd like to do that sort of thing with my XP box here at work, but most of the resources I've found online seem fairly complicated and heavy-duty. Is there a way to do this that doesn't involve mucking about in the registry or running a large batch file? EDIT: My original reason for asking this was that I only need the command line for one command in one specific folder, and I wanted to be able to get to that folder quickly when I launched the command line. But the accepted answer for this question is so good that I decided to ask about my original issue as a separate question here.

  • After logging out of SSH, screen sessions disappear on Arch Linux

    - by Ivan
    On Arch Linux (I'm on a single dedicated server, where my domain name points to only one IP), when I SSH into a user (say, for example, user mc), and then do screen -S test (or -dmS, the resulting issue is the same), run a command, and then detach from it, then exit out of my SSH session, and log back in, the screen session disappears. screen -ls returns No Sockets found in /run/screens/S-mc. The only way I can reattach to my sessions is if I never logged out of my SSH. How do I fix this? I do have read/write access in /run/screens/S-mc I detach from screen sessions with Ctrl-A,D disown -a && exit gives me the same problem shopt huponexit returns "huponexit off" There is no ~/.logout, and ~/.bash_logout is empty, with 3 lines of comments, telling me it's the ~/.bash_logout file ls -l /usr/bin | grep screen returns lrwxrwxrwx 1 root root 12 Oct 31 2012 screen -> screen-4.0.3 -rwsr-xr-x 1 root root 363672 Oct 31 2012 screen-4.0.3

  • Weird behaviour/rendering of backspace in Terminal.app when SSHing into zsh

    - by Nils Riedemann
    Hi there, I just stumbled upon a weird problem. When I SSH into my server (centos, zsh) and I type some stuff and hit backspace It looks like a space - but internally it really deleted the characters. ls -l a Note that the space between land a is actually when I hit backspace. When I now hit return ls -a gets executed. This is only in zsh, in bash it works fine. Hope anyone has an idea what this is all about and how to fix this.

  • How do I create an ISO image from a directory structure on CentOS?

    - by tom smith
    I'm trying to figure out the exact mkisofs cmd to create the ISO with the following directory and file structure. I've tried different commands, but when I mount the ISO that is created the directory tree has not been reproduced. The initial directory tree is: master.iso:: mount -o loop /apps/vmware/master.iso /mnt/vmtest ls /mnt/vmtest isolinux ks.cfg upgra32 upgra64 upgrade.sh ls /mnt/vmtest/isolinux boot.cat initrd.img isolinux.bin isolinux.cfg vmlinuz I've used different variations of the following mkisofs command without success: mkisofs -o '/foo/test.iso' -b 'isolinux.bin' -c 'boot.cat' -no-emul-boot -boot-load-size 4 -boot-info-table 'isolinux' How do I make an ISO that captures a directory's exact structure?

  • Broken characters in filenames only in some directories

    - by Kaivosukeltaja
    We have a web server running CentOS 5.8 that uses SVN for version control. When trying to switch to the latest revision, we got an error about the filenames of files in an upload directory: svn: Error converting entry in directory 'adm/emails/upload' to UTF-8 svn: Valid UTF-8 data (hex: 54 79) followed by invalid UTF-8 sequence (hex: f6 6b 69 72) Upon investigating, we noticed there were some files that had broken filenames: $ ls ~/public_html/adm/emails/upload/ Ty?el?m?trendit.csv Ty?kirja1.csv To get the update completed quickly, we simply mved the files into our home directory. Surprisingly, their filenames looked fine in their new location: $ ls ~/ Työelämätrendit.csv Työkirja1.csv After the update we moved them back to where they were and their filenames were broken again. What could cause this and how can we fix it? The system's locale is set to LANG=en_US.UTF-8.

  • Problem with SVN filename encoding on Mac OS X

    - by Albert
    I have some filename with some Unicode character in it. All filenames on Mac OS X are UTF8 encoded. Also $LANG is set to en_US.UTF-8. However, it seems svn has some problems with that: az@ip212 1054 (Integration) %ls Abbildungen Verbesserungsvorschläge_Applets.odt AllgemeineAnmerkungen.rtf Verbesserungsvorschläge_Applets.rtf Geogebra Vorlagen Texte az@ip212 1055 (Integration) %svn ls Abbildungen/ AllgemeineAnmerkungen.rtf Geogebra/ Texte/ Verbesserungsvorschläge_Applets.rtf Verbesserungsvorschläge_Applets.odt Vorlagen/ az@ip212 1056 (Integration) %svn del Verb*.odt svn: Use --force to override this restriction svn: 'Verbesserungsvorschläge_Applets.odt' is not under version control az@ip212 1057 (Integration) %svn status ? Verbesserungsvorschläge_Applets.odt ! Verbesserungsvorschläge_Applets.odt az@ip212 1058 (Integration) % As you can see, svn del does not recognize the filename. And even svn status gets confused about it. How can I fix this? I also tried with LC_CTYPE=$LANG LC_ALL=$LANG LC=$LANG but no change.

  • Can't get powershell to return where results from GCI using ACL

    - by Rossaluss
    I'm trying to get Powershell to list files in a directory that are older than a certain date and match a certain user. I've got the below script so far which gives me all the files older than a certain date and lists the directory and who owns them: $date=get-date $age=$date.AddDays(-30) ls '\\server\share\folder' -File -Recurse | ` where {$_.lastwritetime -lt "$age"} | ` select-object $_.fullname,{(Get-ACL $_.FullName).Owner} | ` ft -AutoSize However, when I try and use an additional where parameter to select only files owned by a certain user, I get no results at all, even though I know I should, based on the match I'm trying to obtain (as below): $date=get-date $age=$date.AddDays(-30) ls '\\server\share\folder' -File -Recurse | ` where ({$_.lastwritetime -lt "$age"} -and {{(get-acl $_.FullName).owner} -eq "domain\user"}) | ` select-object $_.fullname,{(Get-ACL $_.FullName).Owner} | ` ft -AutoSize Am I missing something? Can I not use the get-acl command in a where condition as I've tried to? Any help would be appreciated. Thanks

  • Do large folder sizes slow down IO performance?

    - by Aaron
    We have a Linux server process that writes a few thousand files to a directory, deletes the files, and then writes a few thousand more files to the same directory without deleting the directory. What I'm starting to see is that the process doing the writing is getting slower and slower. My question is this: The directory size of the folder has grown from 4096 to over 200000 as see by this output of ls -l. root@ad57rs0b# ls -l 15000PN5AIA3I6_B total 232 drwxr-xr-x 2 chef chef 233472 May 30 21:35 barcodes On ext3, can these large directory sizes slow down performance? Thanks. Aaron

  • Why doesn't this script work?

    - by Devin
    I've been using this bash script: for i in $(ls); do mv $i a$i; done to prepend all filenames in a folder with the letter a. I'm afraid that at some point I'll accidentally use this script in the wrong directory and prepend a ton of filenames that I don't want prepended. So I decided to explicitly cite the path to the file. So now my script looks like this: for i in $(ls /cygdrive/c/Users/path/to/Images); do mv /cygdrive/c/Users/path/to/Images/$i /cygdrive/c/Users/path/to/Images/a$i; done It does prepend the filename with the letter a, but it also appends the filename with this ? symbol. Any ideas why it would do that? If it helps any, I'm using cygwin on a Windows 7 box. Thanks for the help!

  • Getting the general log to work in MySQL 5.6.8

    - by Benjamin
    I can't get the general log to work in this version of MySQL. I added the following lines to /usr/my.cnf: general_log = 1 general_log_file = "/var/log/mysql.log" Then restarted the server: [root@localhost ~]# service mysql restart Shutting down MySQL.. SUCCESS!

  • oddities in interference of linux extened ACLs and 'regular' permissions

    - by abbot
    I've got some legacy code which checks that some file is read-only and readable only by it's owner, i.e. permissions set to 0400. I also need to give read-only access to this file to some other user on the system. I'm trying to set extended ACLs, but this changes 'regular' permission bits in a strange way also: $ ls -l hostkey.pem -r-------- 1 root root 0 Jun 7 23:34 hostkey.pem $ setfacl -m user:apache:r hostkey.pem $ getfacl hostkey.pem # file: hostkey.pem # owner: root # group: root user::r-- user:apache:r-- group::--- mask::r-- other::--- $ ls -l hostkey.pem -r--r-----+ 1 root root 0 Jun 7 23:34 hostkey.pem And after this the legacy code starts complaining that the file is group-readable (while it is actually not!) Is it possible to set the extended ACLs in such a way that some other user will also have read-only access, while the file will appear to have only 0400 'regular' permissions?

  • Can't use command line – "command not found" after editing PATH

    - by MEM
    I'm running OS X Mavericks and was trying to install MAMP PRO 2.2. I was trying to configure the PATH variable to have the PHP binaries of MAMP PRO. I added the following line on my ~/.bash_profile file: export PATH=/Applications/MAMP PRO/bin/php/php5.5.3/bin:$PATH As you may notice, since I have MAMP PRO and not just MAMP, I've added a space. As a consequence, I know have the following error each time I run the terminal: -bash: export: `PRO/bin/php/php5.5.3/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin': not a valid identifier Worst: I can't get any command to run, like: ls, clear etc. I always get: "command not found" I don't even know the absolute path for ls. How can I make the commands work again, so that I can properly fix the path I was trying to setup on the .bash_profile file?

  • Too Many Files In Debian Linux Folder?

    - by Dave Potts
    I've been using an external USB drive on a Debian server for backup. The drive is formatted as NTFS and mounted with ntsfmount. This was working fine, but I was filling up a directory with lots of files. Eventually the backup failed. When I then tried to look at the directory using ls it reported: ls: reading directory .: Numerical result out of range Looking in syslog, I also saw this: Sep 23 07:35:31 tosh ntfsmount[28040]: Failed to read index block: Numerical result out of range. Is this simply that I've reached the upper limit of number of files in a directory? If so, is there any way to extend the number of allowed files?

  • Can you share wisdom on using HISTIGNORE in bash?

    - by sage
    I was reading the manpages for bash on the plane and I stumbled across the HISTIGNORE variable. To test it out, I immediately edited my .profile to define this variable: export HISTIGNORE=ls I tested it out and this is great! It excludes plain 'ls' commands from my history without excluding more interesting commands with lengthy paths, but having recently harvested a great deal of wisdom from SU I am eager to know what other commands superusers might recommend or other lessons learned. What can you share about using the HISTIGNORE variable in bash? (Note: I'm about to board my next flight and I have obligations upon arrival, so I will be absent for a number of hours before I can respond to comments...)

  • Cygwin file and directory user and group

    - by dvanaria
    I use Cygwin as my main development environment on both my home and work computers. In order to share files between the two computers, I use Dropbox, which is installed in the following folder on both computers: c:\cygwin\home\dvanaria\dropbox Everything works great, except for one thing. When I'm working on my home computer and do an ls -l on any directory, all the files show up as owned by dvanaria of group Users. But when I work from my work computer, an ls -l shows all files as being owned by Administrators and of group Domain Users. I know Cygwin uses some kind of mapping between Windows users and permissions to the /etc/passwd file. But to be honest I have no idea how this file works or how it maps to Windows under Cygwin. Could anyone help figure this out? The main problem is that I can't edit any files when using my work computer, only read them.
