Help for PuTTy.

agnivaccent — Wed, 25 Nov 2009 09:37:17 GMT

I'm using PuTTY to establish a SSH connection to a remote UNIX machine. I need to fetch a file from the remote system into my local Windows system.

Is it possible? If yes, how can I do that?

"Connection closed by remote host" while doing ssh to a solaris box

How to pass arguments to an interactive script

geek.ksa — Tue, 24 Nov 2009 05:49:52 GMT

Hey guys,

I have an interactive script that is quite critical to our production environmentl thus updating it to run non-interactively is not an option.

The script takes a varying number of arguments, which it ques untill user confirm end of data entry

e.g of user input [arguments]:

Code:

1

2

y            #add another arguments set

3

4

n            #this is last set of arguments

y            #start processing

the arguments to be passed to the script are in a file. say file.in

i tried using a here-document, but it turns out that you can't put a here-document in a file as i kept getting "terminator not found" error message from ksh
i wanted to run the script like this:
script << here_doc

where here_doc had:

Code:

$

arguments

$

it didn't work! as explained above.

now the funny part, if i pass the arguments through a pipe to the script standard input, it works when using echo or print to print the arguments to standard output:

i.e. [Korn shell]

Code:

echo "1\n2\nn\ny" | myscript

^^ this works perfectly, my script runs and reads its input from the pipe. print also works as above

but my problem is, i have a file of these arguments that i want the script to sequentially read its input from.

if I use cat, it doesn't not work!!! the script reads NULL in the first variable!!

Code:

cat file.in | myscript

the same also happens when I do
myscript < file.in #script reads NULL in first variable

by the way, the script that is trying to run this script is on another machine so it ssh-es to the host machine and run the script. But i don't think this has anything to do with all this.
e.g.

Code:

ssh me@remotehost 'myscript'

Can anybody please suggest something to get myscript to read args from a file?

Thanks in advance

http over nfs

marcpascual — Sat, 21 Nov 2009 08:28:15 GMT

hey all,

would like to ask if anyone has ever had any bad experience in serving http over nfs? (document root on nfs)

why should i avoid this, if its not recommended?

if the answer is nfs locks, i can tell apache to create the locks on local fs.

are there any other caveats apart from that?

Thanks,
Marc

Modifying syslog.conf

goose25 — Thu, 19 Nov 2009 17:20:14 GMT

I have a RHEL box that I want to be the loghost for all of the other systems on my network and have set up a /logs partitions to hold all of the logs. I've also created a file called current.log that will contain daily logs and created it using the following command: cp /dev/null current.log. After that I went into syslog.conf and edited the file and added this entry:
*.info /logs/rsyslog/current.log

Once this is setup the syslog service is stopped and restarted and when i check the current.log file there are messages being written to it. Once I go back into the syslog.conf file and edit out the *.info file info and revert back to normal the system starts logging messages again. :confused: Does anyone have any ideas why the system won't write to the current.log file?

Replace value in files

killos — Thu, 19 Nov 2009 10:28:05 GMT

Hello All,

Please if I could get some help on the following, I have data files (due to 3rd party mistake) within each data file on line/row 3 column/field 3 - there is value '1' that need to be changed to '0'.

For example:

HEAD, TYPE OF FILE
NAME,ADDRESS
M,TYPE, 1

Now initially only two data files had the problem, so I was manually changing the 1 to 0 (as the 1 shown above) - but now I've found over 1000 files that actually have the problem (and apparently need to be changed to 0 in the next two hours). I trying to write a Unix script that does all files in one go by using AWK and SED command, or any, But I'm getting no way, any suggestion (all are welcome) .....

I am trying to FTP files from windows to UNIX (IBM AIX). After having sent the files to unix server. Permisssion of the files becomes 640 (rw-r-----). I have to manually login to unix and do chmod 644 on the folder to give it permission. Is it possible that the files automaically be set to 644 on ftp from windows to unix.

Track user commands

mishkamima — Wed, 18 Nov 2009 07:46:49 GMT

Hi,
I have a unix server and I am concerned about the security on that server.
I would like to be able to write a script that records all the commands that were typed at the command prompt before the user calls the 'history -c' command and deletes all the history.
I was thinking about firing or triggering that bacth script upon the call to history. Is this doable and if not are there any other alternatives?

Thanks --

Postfix config

fisfia — Wed, 18 Nov 2009 07:32:24 GMT

Hi,

I have a problem with configuring postfix. Would like pf to limit the amout of mail that a client can send in for example one hour.

Thought maybe this would be a good idea:

Code:

smtpd_client_message_rate_limit=

But what happens then is that smtpserver sends maximum amount for that time unit then WAITS until it's ok to send again.

All the mail are finally send, just they get queued until it's done. That is not what I want.

I would like to have the possibility to warn the client and then reject further mail. Not delay to queue.

Is it possible? Should I instead use another parameter which is more sufficent for this task?

Most people recommend policyd on this but I would still prefer to do it within postfix if it is possible.

Would be very greatful for any help, thanks!
