...nd - such that find is able to see a file whereas ls says the file doesn't exist. Initially I was trying find and ls together as: # find ./ -type f -mtime +15 | xargs ls Similar behavior is seen even when I execute both commands separately. Any thoughts on what might be wrong here? -- thanks, neubyr

Howdy, I have renamed a directory on NFS ver 3 server and then created a new directory again with the same name. # mv dir dir-hosed # mkdir dir The directory is auto-mounted on client side. I had unmounted directories on client side before making above changes. Now when I try to mount back 'dir', I still see old files and not new empty dir. Am I missing something here in the NFS config?

How do I pass xargs input one line at a time to subsequent command? For example I want to install rubygems by reading a text file as shown below, however the arguments are getting passed all at once to the 'gem install' command.

I saw option as - 'url --url http://<server>/<dir>'. I am not sure what should be the directory contents? Should we put all ISOs in that directory or what? Any insights? Thanks, CS.

Howdy, I have a diff file in my /var/tmp and would like to apply patch to a file in a different directory (other than /va/tmp). I tried using patch with -d switch, but that doesn't work.

Hi, I need to maintain a same user/group list on multiples systems. Can we just copy the same passwd and groups file on all machines? If we create a new user on one system then I will need to copy this to all other systems. This is quite cumbersome. Any suggestions? - CS.

I am using autofs to mount user's home and group directories. The setup works fine for home directories which are mounted after user logs in. The group shares are also mounted, but user has to manually do cd or ls command on group shares, e.g.: ls /groups/chemistry will mount chemistry group share. Is there any way to mount group shares automatically? I noticed that after successful login

Hi, I need to mount a LVM in rescue mode to create a new initrd image. I am not sure how do I fond out which LogVol is to be mounted. How do I find it out? In most of the configs I have used LogVol00 with ext3 filesystem which contains OS install. This particular system is not installed by me and I am not sure how do I find it out. I did try 'lvm lvs' command, but probably that's not

Hi, I am not sure how to configure LDAP authentication with samba. I have a windows box, which is part of Active Directory domain and does user authentication against it. I would like to use same user credentials and map them to a appropriate network drive (linux home dirs). In short, Linux user's home dir should be available on Windows box also. I looked at the smb.conf man page, but I

Hi, I have a autofs configured to mount home dir from NFS. All user accounts lookup is done using LDAP. All is working fine with this setup.

I am forwarding traffic on port 8080 to port 80 with following rule. # iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 8080 -j REDIRECT --to-port 80 # iptables-save However, I am unable to add it directly in /etc/sysconfig/iptables. I think it is used only for filter table and not nat table. So where do nat table rules go? Any help? - cs.

I am writing a small script to kill process(es) listening on particular port number. Here I am particularly looking at Java servlet-containers like Tomcat and JBoss, which sometimes don't complete their shutdown process and it still shows up as running process with ps or netstat. This needs to be kill-ed and for that knowing pid of that process is necessary. The netstat by default doesn't
