View 1 Replies View RelatedThe issue is that my CentOS workstation is in a vlan from where the Intranet's DNS servers are unreachable. For browsing the web there is an ISA proxy server, which I presume resolves DNS for my firefox. However, wget, host, ping and aria2c fail to get any sort of DNS resolution since they're being run from command line.I have exported HTTP_PROXY value, which provides me internet access on console, but,only when I connect using IP address. It fails on name resolution.
My question is:May I redirect the DNS queries to my home PC which would be running a DNS server on a non standard port?I was thinking of putting nameserver 127.0.0.1 in /etc/resolv.conf and then put iptables rule to redirect 127.0.0.1:53 UDP to a.public.ip.address:3535 UDP..I don't know if I am shooting blanks or what, I am not very much aware of this kind of setup.My main need is to provide DNS resolution to console apps.I want to utilize my company's idle bandwidth for bulk downloads, so, using proxy, SSH tunneling through my Home PC is out of question.

I wrote a short script that sleeps for 30 seconds then outputs "Done" to the screen:
sleep 30
echo Done
now I want to re-direct the output to a file, I tried:
./scriptName& > fileName
Didn't work, "Done" still came out to the screen.
I have a python script that when run outputs to screen.
eg.
./international_sms_check.py 0403000511 919227434827
TS 21 check ok
TS 22 check ok
sms successfully delivered from 61403000511 to 919227434827
But when I try:./international_sms_check.py 0403000511 919227434827 > test
The file test is created but there is nothing in it.if I try ls > test this works fine with output of ls redirected to file test.
I am trying to automate an svnadmin dump command for a backup script, and I want to do something like this:
find /var/svn/* ( ! -name dir -prune ) -type d -exec svnadmin dump {} > {}.svn ;
This seems to work, in that it looks through each svn repository in /var/svn, and runs svnadmin dump on it.
However, the second {} in the exec command doesn't get substituted for the name of the directory being processed. It basically just results a single file named {}.svn.
I suspect that this is because the shell interprets > to end the find command, and it tries redirecting stdout from that command to the file named {}.svn.
I have a program that writes to stdout. Is there a way that I can redirect the output to the linux diff command or do I have to write the output to a file and then compare that. For example I have a bunch of test input files for a program and the corresponding expected output in another set of files. And I'd like to do something like ./program < t1.input | diff t1.expected.

I'm working on some scheduled task script files to keep nightly backups of some of our database information in place, and it's a bit annoying when they blow up. I know how to redirect stdout and stderr to a flat file I can view when I come in, and I know that 2>&1 maps them both to the same file (whatever was named in 1). However, I'm running into some cron-time situations where it's easier to have the two streams together, and other cron-time situations where it's easier to have them separated. I can't really tell which is going to happen; is there some way I could create both kinds of output file for my scripts, so that I've got a std_err only file and an interleaved std_out/std_err file?
Note: I've looked at the 'tee' command, but I don't think it will work for what I'm after. 'tee' appears to only work with stdout; I'm trying to work with stderr.

View 2 Replies View RelatedHow do you transfer a file from a local Mac to a remote Linux machine
View 5 Replies View RelatedI have a Ubuntu server hosted on Amazon EC2. I need to create an automated backup scheme so I created another Ubuntu instance on my local network which is hosted in a virtual environment. I managed to transfer the necessary files between 2 machines on the same network using the rsync command:
rsync -azvv -e ssh /home/path/folder1/ remoteuser@remotehost.remotedomain:/home/path/folder2
How can I do the same thing but transferring files from my Amazon server to my local server? Is there a way I can achieve this with port forwarding, or by VPN, or anything else? It doesn't have to be rsync. If you know about a better method, kindly let me know.
I know I can ssh login without password from a local to a remote. My question is how I can ssh without password from the remote to another remote. Say, I have three machines: A, B, C where A is the local machine. I use the same private/public key pair for all the login. What I can do are:
1. ssh from A to B.
2. ssh from A to C.
3. If I am sitting in the computer B (or B is local), then I can ssh from B to C.
What I am not able to do is:
After I ssh from A to B, I cannot ssh from the B to C. When I try to ssh from B to C, it asks me a passphrase.
Is is possible to move a process from one shell to another (local to remote)

I have a problem while copying files from a remote computer to my local one using the scp command. I am sure that I am using it correctly, please check it below:
---
blah@blah.com:~/g4work> scp blah2@blah2.com:IndirectMethod_Spher...s/H_1.mac.root .

What I get in return (instead of the statement saying 100% of file copied) is:
---
On this machine the G4SYSTEM=Linux-g++

The interesting point is that the above returned statement is one of the Environment variables set on both the machines that are necessary to work with a toolkit called Geant4. Here is what I get when I type 'printenv | grep G4' just to show you (note the statement in bold):

I am again struggling to make a script work, but hey, it is fun, I am learning new things. I discovered the set -x option which was, for me, like the second coming. Still, what I am not able to do is redirect ALL output to a (log) file, including what is produced by the -x setting. Let's assume a very simple script:
Code: #!/bin/bash
set -x
source="/home/atelier/Bureau/"
ls -la $source and I am running it as . test.sh >> /var/log/test.rmcb.log
The result of ls goes inded into the log file, but the rest still shows on the console where I am running the script: Code: ++ source=/home/atelier/Bureau/
++ ls --color=auto -la /home/atelier/Bureau/ Is there a way to redirect EVERYTHING to the log file ?
