View 1 RepliesThis problem is occurring on Red Hat EL 5 WS. However, I have two CentOS 5 systems, with similar configuration to RH EL 5, where this problem does not occur.
I am getting this error:

Can't execute sendmail -t: No such file or directory
I need to write a script that executes a wget. The difficulty being, if wget just sits there with no reply for a very long time, I don't want the script to run that long.
How can I time out the wget command in the script if it doesn't give me a reply in a minute or so?
I'm experiencing an occasional frustration using Evolution with my work email which is on an MS Exchange 2003 server.Everything usually works well enough, but from time to time I'll try to retrieve a message,Is there a setting I've missed in Evolution that might take care of this, or some other workaround?Let me re-emphasize that the server is a 2003 Exchange server (and a source of endless frustration for a non-windows user). It's not a 2007 or 2010 Exchange server, which is what most companies use these days.

Had to do a fresh install of 10.04 as upgrade went pear shaped. Now I cannot get hunderbird 3.0.4 to work just keeps timing out trying to access mail server pop.1and1.co.uk.Had to change some Firefox options to get it to work with any site other than google.Noticed that ping pop.1and1.co.uk sometimes gave a bad address until I disabled IPv6.

I am a linux newbie (more so with using RedHat). I am trying to use yum to install packages, but have never really able to get this thing right. I want to install libXp-devel package. However, running yum install libXp-devel doesn't work.
When I downloaded the rpm for libXp-devel and tried to run yum install libXp-devel-1.0.0-8.1.el5.x86_64.rpm, I get the following:
Code:

I am having, just installed a fresh 9.10. The only thing I did was an update and installed the wireless drivers. Well i went to to download my favorite browser Opera and firefox just times out. I can get to other websites just fine so far. Though it looks like Office Depot won't let me in either. If I boot into Windows I can connect to either site just fine.

View 3 Replies View RelatedHave had issues with my 10.4 Server regularly. I believe it's something that I've done wrong in some of the hosts settings or the like. When I try and login to the server, especially on startup, I get messages saying the login attempt timed out after 60 seconds and when I login via ssh it boots me from the connection after about 60 seconds of trying to login. It's after entering the password so it's something to do with authentication most likely. I think the issue is with my /etc/hosts file as I said before. Hostname is blackbox and it's only meant to be a local network server.
/etc/hosts file:
Code:
127.0.0.1 localhost.localdomain localhost
192.168.1.5 blackbox.localdomain blackbox
# The following lines are desirable for IPv6 capable hosts

It seems to find a ton of updates and takes a long while to DL everything.Do I have to tell it to install the downloads? I don't think I do...I get some errors about timing out for the last few updates.theni reboot, but when i check redhat-release it still says 5.3
A few weeks ago I upgraded one of my laptop from Fedora 13 to Fedora 14 (using pre-upgrade). The upgrade went smoothly and no errors appeared. However ever since the upgrade ssh is not working anymore. I've tried various servers inside and outside the local network. I can't contact any of them. In all cases I get:
Code:
ssh: connect to host aaa.bbb.ccc port 22: Connection timed out
I've tried to get more info using the -vvv option form ssh, but it doesn't mean too much to me:
Code:
OpenSSH_5.5p1, OpenSSL 1.0.0d-fips 8 Feb 2011
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to aaa.bbb.ccc [xxx.xxx.xxx.xxx] port 22.
debug1: connect to address xxx.xxx.xxx.xxx port 22: Connection timed out
ssh: connect to host aaa.bbb.ccc port 22: Connection timed out
Actions so far:
- checked internet connection. No problem there. Another laptop is working fine using the same connection and the same ethernet cable. That laptop is still using Fedora 13, since I didn't want to get stuck without ssh completely.
- checked "messages" log. No messages at the time of ssh connect attempt.
- checked "secure" log. No messages at the time of ssh connect attempt.
- checked the firewall settings. The settings are exactly the same as before the upgrade (when ssh was still working). Moreover, the settings are the same as the other laptop that is working.
- temporarily switched off the firewall. No difference.
- temporarily switched off selinux. No difference.
So it doesn't seem to be a firewall or selinux problem. And I know the connection is working, so it does not seem to be a routing problem either. What am I missing here?
System specs:
- Asus EEE PC (1 GB RAM, intel atom processor);

In the beginning there is MBR. MBR looks for the active partition and tranfers control to the VBR of the active partition. MBR is where grub may be installed. which allows the user to choose an OS(a VBR) I am not sure what the program in the VBR does,but it manages to loads the OS. What am I trying to do: Backup. I ma tired of losign my partitions my bootloaders. I want to backup them all! partitions/MBR /VBR everything short of creating an disk image.
My questions:
1. say the ubuntu partition is formatted, will grub still load? if not is there a bootloader that would?am I making sense? i hope so...
2. what exactly does the VBR contain ?
2. How do I go about backing up? The mbr and the partiton table are backed up with a simple dd command. Then what else needs to be backed ? VBR's of every partition?

I just installed my first ever install of Linux (used Fedora) and am using SSH to access it from my Windows machine. It keeps timing out. Is there something I need to set to make it available all the time?
I was able to get the SSH on and to autostart just fine but when I boot up it only works half of the time. I have to move the mouse and keyboard on the Linux machine before it will respond.
Also if I am working on my Windows machine and don't move the mouse or keyboard every now and then it doesn't work.
Well I get my other 2 questions answered , I have one last question that has been buggy me.Anyone know why windows use so many files just to keep the OS going and so bloated? The under line of files of windows is messy and loads self every where and very bloated with windows and windows vista and windows 7 very much so.I'm not sure if Linux /Mac OS X is like this or not .
I know windows needs to support alot more software and hardwar but is that not where drivers come in for the hardware.And programmers need to write the software for windows or Linux / Mac OS X.
I write a little script by bash.
#!/bin/bash
a=`gawk '/Iterations /{print $0}' hoge.log | gawk 'BEGIN{FS=" "}{print ($4)}'`
a=`expr 3 '*' $a`

In my book, this is an example of a recursive algorithm:
var reverseArray = function(x,indx,str) {
return indx == 0 ? str : reverseArray(x,--indx,(str+= " " + x[indx])) ;; }
var arr = new Array('apple','orange','peach','lime');
var str = reverseArray(arr,arr.length,"");
alert(str) ;
I'm trying to understand it, I'm stuck at the (str+= " " + x[indx])) part - that part of the function definition expects an ARGUMENT, am I right? What's being passed to it is a bit of PROGRAM, the str+= stuff. So - how is it working?
I don't understand the output from 'free' cmd.

Running a LAMP server, CentOS as the OS.The sites always been slow, but now that ive optimized it with mysql cache, gzip compression and some other things, its really fast.Except when pages loading seem to randomly 'time out'. The browser sits on 'waiting for x.com'. Closing the browser and/or the tab and opening a new one fixes it, but then it'll happen again eventually. Clicking further links while its 'waiting for x.com' does nothing, basically the site becomes unusable until you close the tab and reopen it.
This happens on all 3 virtual servers we're running within apache. Mainly noticable on the PHPbb forums, probably because they are visited the most.It's not a slow mysql query, i turned on slow query logging over 2 seconds, and the only two hits i got on that i know are unrelated.Ive turned off some optimizations thinking they might be it, but no dice.
