Permissions problem
What am I doing wrong here? I need to be able to write to /var/cvs. This used to work before I moved these groups into an LDAP directory instead of /etc/group: [scarolan at watcher:/var/cvs]$ touch test.txt touch: cannot touch `test.txt': Permission denied [scarolan at watcher:/var/cvs]$ ls -ld drwxrwsr-x 4 cvs cvsgrp 4096 May 18 2008 .

Good md5sum snapshot tool?
I have a server that is undergoing some patching soon and would like to make note of any files that have changed after the patching is complete. Can you recommend a tool that uses md5sum snapshots to do a quick before and after test, showing anything that's changed on a particular file system?

Best mobile SSH client?
I'm up for a cell phone contract renewal and am considering upgrading my handset. I looked at some devices at my local AT&T store but nothing really jumped out at me. I'm particularly interested in a cell phone that has a reliable ssh client, with ssh-agent and public key authentication abilities. Those of you who administer systems remotely, what mobile ssh client do you recommend?

Gnu Screen - terminal issues
I really like gnu screen and use it everyday but there's one thing that is a bit inconvenient, and that's the odd line wrapping and terminal size issues that seem to pop up. The problem crops up when I type or paste a really long command, and then go back and try to edit it; the text starts to wrap over itself and you have no idea what you are editing. Any fixes for this?

Limit RAM used by a perl script
I have a perl script which runs from a cron job. How would you limit the amount of RAM that this script is allowed to consume? Is there a ulimit setting that will accomplish this? If so does ulimit have to be run each time the script is run, or is there a way to set it permanently?

Help with iptables rule for blocking UDP port 53
I would like to block all DNS queries that come from one particular ip address. I used TCPdump to verify that the queries were in fact, coming from this IP: [scarolan at server:~]$ sudo tcpdump -n udp port 53 and src 10.100.1.1 tcpdump: listening on eth0 11:12:17.162100 10.100.1.1.19233 > 10.100.1.61.domain: 14270+ A? server.domain.com.

df to get total disk usage on all filesystems?
Is there a flag for the df command to get the total disk space used on all filesystems as one number? I have a server with a lot of mounted shares. I'm looking for a simple way to measure rate of data growth across all shares as one total value.

XDMCP - no GDM login, only gray screen with X
I'm having trouble getting the GDM login screen to show up when I connect from a remote host. I'm using Xming on the local Windows machine, but every time I connect to the remote server all I get is a gray window with the X cursor. I have "Enable=true" in the [xdmcp] section of /etc/gdm/custom.conf. IPtables is disabled. I've googled around and read through the xdmcp page

ntpd stuck on stratum 16 = not synced
Maybe there's an ntp expert out there who can help me with this. I have an NTP server serving our local network. It is set up to use pool.ntp.org servers for it's upstream sync. ntpq -p reveals that the server is stuck on stratum 16, which I understand means "not synced". The clients are unable to sync with my local server because of this. Here's the output of ntpq -p

Rsync - include only files containing matching string
I have a string, "2012_10_16"; let's call this $YESTERDAY How can I rsync a file tree from a remote machine to the local one, including *only* filenames that contain the matching string? I've read the man page and googled around but can't seem to get the syntax right. I either end up syncing all the files, or none of them. Here's how the code looks now (I will remove

Good version control package?
We have a directory full of installation and configuration scripts that are updated on a fairly regular basis. I would like to implement some sort of version control for these files. I have used SVN and CVS in the past, but I thought I'd ask if anyone can recommend a simple, easy-to-use tool that would be better than cvs or subversion for this fairly simple setup.

e2fsck with millions of files
I have a large (1.5TB) partition with millions of files on it. e2fsck has been running nearly 12 hours and is still on "Checking directory structure".

NTP Service Running on Local Host does not Sync System Time
Hi List I have ntp running as a service on a PC, with the expectation that it would keep time in synch to my ntp server. However, while I can manually update the time using "ntpdate -u ...", I find that if I manually force the wrong time, the ntpd service does not automatically re-synch the system time with the ntp server: - Current time: [admin at lol ~]# date Wed Jan 27 10:54:21

Iptables not blocking UDP port 53
I'm attempting to block access to port 53 from internet hosts for an internal server. This device is behind a gateway router so all traffic appears to come from source ip 10.100.1.1.

/etc/hosts - hostname alias for 127.0.0.1
Can anyone point out reasons why it might be a bad idea to put this sort of line in your /etc/hosts file, eg, pointing the FQDN at the loopback address? 127.0.0.1 hostname.domain.com hostname localhost localhost.localdomain

One for the Cisco experts...
I have a Cisco 6509 switch that I'm monitoring with SNMP from a CentOS5 machine. SNMP polls are the only access I have to this device, we are not allowed to log on via telnet. How can I find out which port on the switch a particular server is connected to? I was hoping that this is somehow possible using the mac address and the data gathered from snmpwalk/snmpget requests but I'm not
