I cant get ntpd to synchronize with the ntp servers. I have a CentOS 5.3 32 bit Virtual Machine. I'm in USA on Pacific Standard Time. Here's all configuration and other important information for troubleshooting. Is there anything wrong with my config? btw, I used wireshark to look at the UDP packets - I dont get any responses from any of the servers back. I only see requests going out from my server, but no response. Is this a firewall Issue? If it is, then do I need to just enable UDP port 123 on the firewall?
As soon as i'm starting to copy a large file enough file (>700Mb) to my ubuntu box (connected to an Asus router via wifi) from a Windows 7 client (connected to router via ethernet cable) i get a dramatic drop in speed. upload starts at 1,0Mb/sec with a ping to ubuntu box at <1ms, and in 2 minutes it drops to 200kb/sec with a ping of over 1000ms! The ping increases with every second in a linear progression.
To exlude router as a possible problem copying to a windows 7 notebook connected to router via wifi results in an average of 2,7Mb/sec with an average ping of 150ms.

I had CentOS 5.2 Upgraded to 5.3 -- when will I learn to test more. Anyway, same everything and samba won't stay up. I'm constantly doing service smb restart and then a few seconds later the shares are gone and I have to run smb restart again.
I have just installed a fresh copy of CentOS 5.3 and from the get-go, the NIC started dropping packets like crazy. I even closed the port on the switch,. moved the cable to a different port,. All yield the same "dropping packets" behavior. Zero on the errors, just dropping packets. Should I stick a diff nic instead?
After doing a clean base install of CentOS 5.3 on a test server, I started having problems with network disconnects. While SSH into the box, I would be intermittently disconnected from the SSH session. At first I thought it was my workstation, but after running ping tests from multiple machines on the network to the test box, it became apparent that the test box was dropping packets. When I lose my SSH connection, the pings also start timing out, for a few seconds, then start again. I increased the console logging and I can see when the ethernet port goes up and down when I physically disconnect the cable, but it does not go down or lose link when the disconnects occur. I changed the NIC ports being used and had the same result. I tried with a different switch with same result. I reinstalled CentOS 5.2 and the problem went away.
Upon further investigation, I found that CentOS 5.2 is using the e1000 driver for my NICs and CentOS 5.3 is using the e1000e driver. I resinstalled CentOS 5.3, and tried using the e1000 driver instead of the e1000e but it no longer detects my NIC's... apparently they moved the support from e1000 to e1000e. I have spent the last 3 days googleing for info on this problem and have not found a solution. Any recommendations? Should I submit a bug report?
just prints out a long option list and quits... sometimes it tells me that I cannot connect to localhost.... I've tried --no_defaults,--socket= etc. as per the MySQL manual.
MySQL 5.0.45 I know the server is running This is a new install and i'm su'd to mysql in mysql homedir. I'm sshing into DV Centos 5.
I want to send mail to potential customers from my localhost server in my SOHO. I have a web site hosted with a company called geek hosting [URL], so I have access to the mail services through them... I want to their mail server to push things out to the world form my localhost server.
I do have a registered domain name which the hosted site runs under
the domain name for my centos 5.4 server is localhosthost.localdomain.
it was not working and ping is not reply me and I add ifconfig lo 127.0.0.1 it is working and getting ping but when reboot it is lost setting how can I set it for always ping working.
PING localhost (127.0.0.1) 56(84) bytes of data. ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ifconfig lo 127.0.0.1 later

now working but IWant reboot later working about same. how can I setting it boot start this .
We installed CentOS 5 at our school and are attempting to get 2 simple DNS servers online. These are simple name resolution servers for our network. We installed the needed caching nameserver packages via Yum and all seems to be well, but for some reason when the server is online, it fails to resolve DNS records except when we direct the requests to its 127.0.0.1 (localhost) interface. As for the server specs, the DNS server is running on a Virtual Machine, and the ESXi server has 2 quad-core Xeon CPU's with 48 Gigs of RAM (in short.. hardware is adequate.)
Here's more details: When the box boots up, we can confirm that the named service is running and it resolves DNS records when we direct queries to its localhost address: [root@ns1 ~]# dig hotbot.com @localhost ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> hotbot.com @localhost ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 55510 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 4, ADDITIONAL: 0 ..... ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> hotbot.com @66.186.176.2 ;; global options: printcmd ;; connection timed out; no servers could be reached
What would cause the Named service to not answer DNS queries from the physical IP but only from it's internal IP?
Having a problem with tftpd on CentOS 5.5. I am only able to download files from the localhost address.
I have checked iptables (by adding rules and by turning the firewall completely off -- nothing changes) and enabled tftpd logging (by adding -v to the server_args section in xinetd.d/tftp) and I DO see the request coming in, but no response from the daemon. I've also tried upping the verbosity by adding multiple -vs and/or --verbosity 10 to the mix, but all I ever see is the initial request come in, nothing more. I've even tried running the daemon in foreground mode with -L but I get no verbosity then.
I followed this tutorial for setting up my server. Whatever I type into mysql or mysqladmin all I get back is Quote:ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
I have installed bind from the repos and am trying to setup a caching name server. After copying the stock name-cachinging.conf to named.conf, I tweaked named.conf to reflect my LAN:
options { listen-on port 53 { 127.0.0.1; 192.168.1.102; }; listen-on-v6 port 53 { ::1; };
I'm running wordpress and have gone to the painstaking effort of setting up the ftp server on my 5.3 machine so it can do its own updates and download plugins. However, I've found that if I try to download anything, I get a "unable to resolve host..." error from the script. If I watch Iptraf while making the request, I see all the port 53 requests going to 127.0.0.1. Pings are too.
However, if I ssh in, I can ping and wget and whatever I want all day long and all the DNS requests to go the router (Clarkconnect 3.2 gateway machine). The web browser in the terminal works fine too. What is it about the php scripts that is causing them to misdirect pings and dns requests? I've never seen anything like it and can't find anything on the web about it either.
I have setup a Linux Centos with apache server on it in a home network. Everything works fine. When I access the webserver I put in the address bar the IP address of the server which is 192.168.0.150 and when hit enter, it prompts the page where I have to put login information. The login information is set to: username: admin@localhost.local password: *************
It takes long time for authentication go through and load the page eventhough I am accessing the site in a same home local area network with fast ethernet connection. How can I change the localhost.local to something else like maybe [URL] instead and if I have to change settings in other files as well?
I have recently upgraded to a VPS for the purpose of web hosting a group of sites related to my business.The reason for the upgrade was because we wish to run a shopping cart software which required greater memory for PHP and the VPS was the most economic solution. So, I have very basic linux knowledge but I am the definition of a newbie when it comes to going further than just scratching the surface of server configuration! I have successfully hosted our main site for a number of weeks but recently the postfix service stopped sending mail. I have Plesk Control Panel installed and postfix continually shows as not started even though in SSH the service status is definitely running - I have gone through the troubleshooting checklist here (http://www.postfix-book.com/debugging.html#d0e6) but can't get any further than section 2.1 as when running the host command (#host relay-test.mail-abuse.org), I get # -bash: host:command not found. I've gone further in the document but not found any issues...
When postfix was working properly (i.e. sending emails!), the plesk CP showed the service as started and all emails from the website were sending as normal. The mailq command is showing the messages stuck in the mailq and the maillog shows the following:- http://pastebin.centos.org/36446 - these are the latest few pages.To check the configuration and basic elements I have flushed the mailq (which shows a stack of messages waiting) and I have also spent a long time (2 weeks) reading up on the parameters that should be in main.cf and master.cf.I have found that when I 'telnet localhost 25' I get the following response...[root@s15397216]# telnet localhost 25Trying 127.0.0.1...Connected to localhost.Escape character is '^]'.
Basically this is what's happening. I can receive mail in my Maia Mailguard everything works fine.
However in my Spam Cache if I were to get an item say that was not meant to be spam and I try to release it so it goes into my inbox I get this error (see below)
Now I'm trying to figure out where I would give it permission to connect to that IP?
On a side note the error has an IP of 192.168.96.30. With that IP I get a connection refused error
If I were to put Localhost it gives me an error of "Could not find Network_addr"
So I'm trying to figure out what this error means and why I can't release any kind of spam to enter my mail box?
I think it has something to do with the way it is connecting to my exchange? or MySQL?
I 've searched for on a lot of threads and google results, I found no response. Does someone know a solution to synchronize calendar and contacts between a smartphone nokia ( particularly N97 one) and thunderbird with lightning or sunderbird plugins on fedora ( release 11 for me) please?
I'm running a Windows 7 guest using Virtual Machine Manager to launch my "console" to the VM. I believe it uses VNC to connect to the console. I'd like to have clipboard synchronization so I can copy from the host and paste to the guest.
I have two 1TB hard drives, one in my Linux server (running Debian, but I thought I'd ask here anyway) and one in my Windows desktop.
What I would like is a file synchronization program that will automatically (or scheduled via cron) synchronize my hard drive on Linux with my hard drive on Windows via Samba.
My phone is dead or dying so now is a good time to look for a FOSS replacement for Nokia PC Suite and Outlook -- the only reason I run Windows.
Is there any solution (or combination of solutions) that supports synchronising personal information manager (PIM) data -- most importantly names and phone numbers, calendar/schedule and notes -- with any model of cell phone?
EDIT:
SyncEvolution looks promising and there are reports of it working at least adequately with several phones including the interesting for Linux people Nokia N900 but OS-wise it only claims compatibility with ubuntus and debian 4.0, not beloved Slackware; maybe that's more because of what people have tried than because it doesn't work. As the name suggests it works only with Evolution, perhaps not the first choice of email client and PIM.
