I recently got a new server. I installed CentOS 5.2. Here's some more info:
[root@thalamus etc]$ uname -a
Linux thalamus.tch.harvard.edu 2.6.18-92.el5 #1 SMP Tue Jun 10 18:51:06 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
I'm using NFS and I have the following problem. After ~100 days, the client and server lose connection, but the client doesn't know about this, it gives no error. The problem is that the changes on the server side aren't visible on the client side.
The nfs options are: "noatime, nolock, hard, udp, notcp, nosuid, nodev, rsize=8192, wsize=8192, actimeo=60"
The kernel version is: 2.6.16.27 built with 250 Hz. Is this an already corrected issue in a kernel version? Or are my options wrong?
I've tried to read many of the topics in this forum first and tried to find a solution to my problem, but can't find one.I'm testing CentOS 5.5, it's the first time I'm using a CentOS Linux release.I'm trying to configure the proxy "client side " on it and cannot find how to do it.On other Linux release I've used the ENV variable like "http_proxy" or "HTTP_PROXY" etc etc.This time, I don't know why but it doesn't work.I've put the name and @ip of the proxy in /etc/hosts and tried different version upper/lowercase of "http_proxy" "HTTP_proxy" "ftp_pr.." but it doesn't work.If I configure manually Firefox and puting the name or @ip of the proxy we have on our network, it works.But if I try to use ENV variable it doesn't work...

I need to show an output of the command "show interface status" executed on a server side in new window on client side. In other words: on client side web browser page I would like to have a link which I can click and get output of command "show interface ... status" in a new window. On web server script has to connect to switch/router, execute this command and send output to client window.
where to look, and, may be explain, what can be better for this purpose? I need a clue, because I have newer done it before. It should not be snmp, because I want to view many different outputs and snmp wont help me.
Calculating the available bandwidth methods IGI/PTR,PATHLOAD,SLOPS,PACKET PAIR...
I gone through above methodogies ,when i finish one methods(IGI/PTR) i came to know,one application should run in client side and another application should run in server side (i.e,) Internet Service Provider side,
In IGI/PTR method ./ptr-client.c & ./ptr-server.c is there .,if we want available bandwidth,I Should run ./ptr-client.c (in myside)correspondingly ./ptr-server.c then only we wil get a availble bandwidth...
My need is without run any application on the server side ./ptr-server.c like that,but I should develop the application only on client side (in my routerside based on linux)..
1:whether it is possible to get the available bandwidth run application in client side only?.if possible. how i implement the code in client side( only )for getting the available bandwidth ...whether any source code is available?...

i'm unable to see some musicvideos on videos in germany trough copyright restrictions. i can see these videos by using a tunnelservice, but it isn't very comfortable.
in that case, i have to copy the url and paste it at the end of the tunnelservice url. a lot of stupid work.
my problem is, that i haven't enough experience to automate these actions.
i think, that i have to modify the url befor it goes to the server. there must be somewhere in the osi stack a place where i simply can modify that url with a regex but i don't know where
I have hundreds of thumbnail images and I need to display on the client side one name only for each when the visitor passes the mouse over them. The only way I know (using frames in this case) is to use a script similar to the following:
<a href="" target="" onMouseOver='top.nav3.location="not/notecome.htm"' onMouseOut='top.nav3.location="nav.htm"'>
But this involves creating a full and w3c correct HTML document which looks like an over-kill of the problem.
Is there a simpler way to solve the problem? If not, is it acceptable to use a truncated HTML document comprising only the necessary tags to make it work on the test machine (<html><body><.....onMouseOver.....></body><?html>
Or a way to display the content of the "alt" tag (I can put that name there)?
In the worst case, I could use the javascript "Alert" but it does not fit esthetically and it needs one mouse click from the visitor. Is it possible to make one's own "Alert" picture and how?

View 2 Replies View RelatedI would like to be able to mount a share served by my mac os X machine(10.6.1). I have read the Ubuntu community doc on Ubuntu samba clients.It didn't say what to do when using dynamic LAN I.Ps.I understand the way to go is to use avahi on the client side(Ubuntu) and Bonjour on the server side(mac os 10.6.1).I can't find anything about how this is done.What do i need to do to set up the client side(Ubuntu) to use avahi with SAMBA?.Because in the Ubuntu community doc it just referenced /etc/hosts, which is for static I.Ps.So i'm assuming that SAMBA on Ubuntu doesn't use avahi by default.All i need to know is how to set up the client side of SAMBA on Ubuntu when i'm using dynamic LAN I.Ps.

I have a openldap server running on one machine (fedora10) and pam_ldap.so and nss_ldap.so running on the other machine.
I have added a new user to the LDAP server database, this user is not created on client machine.

2. Now if i try logging with this new user I am getting error messages, the error messages are as follows at client side

I've set up a Lan-to-Lan (routed) OpenVPN tunnel. For redundancy I want to set up a second VPN tunnel on a fallback gateway/firewall on the client side. Currently, both sides (server/client) know how to route packets across each others physical LAN. So no NAT is used. When the primary gateway (fw1) is connected to the VPN server all traffic runs via the fw1 tunnel. Than when the secondary gateway (fw2) connects to the VPN server and fw1 is still connected all traffic for fw1 will be delivered to fw2 and effectively destroying traffic intended for fw1. This is of course no problem if I first shutdown (fence) fw1, than set up fw2 to use the gateway IP address from fw1 and set up the VPN tunnel to the VPN server. Effectively replacing fw1 with fw2 on the client side.
However, I can't seem to find a decent howto.
I am also exploring the possibility to let both tunnels active and let OpenVPN (or another tool) decide how to route packets back and forth the different LANs. A virtual IP between two gateway's both running a VPN or something similar. This would be the preferred method of course. However, I don't know how to tackle this one but I'm pretty sure there are people out there who are happy to share their 2 cents.

View 1 Replies View RelatedI can't get the client server to authenticate to the openldap server. I can authenticate on the server itself though. I can su to, login and shh into the openldap server and become a ldap user. I just can't become an ldap user on the client.I didn't setup TLS/SSL. I can do that after I have it working. I'm using hashed passwords though. I don't have replication setup. I'm am tying to setup the most basic openldap environment then build from there. I have read the openldap section in the admin guide.
My setup at home.
Openldap server � light.deathnote.net -- 10.0.1.21
client server � vm-centos01.deathnote.net � 10.0.1.7 -- VM on virtualbox
Virtualbox host � L (OS MAC) � 10.0.1.2

All computer can reach the internet and ping each other. When I installed centos I disabled SELinux.I used these guids to setup my openldap.

The server has no GUI (command line UI) while the client has a UI. I need to install a Simple Forum Machine application and I'm told to FTP the files into the server. I figured out that the best option is to load the files in the client via the GUI and then ftp them in the server. How do I transfer the files from a the client t o the server using FTP?

My office is on migrating to UNIX system. I am configuring Centos as our server including some program will be running on it. But one of the problem is we use foxpro for operating some program on server directly. I can run that program on Centos using DOSBox. My question is how can i run that program on winxp client that connected to network through samba to that program on server? so my plan is just give the shortcut and link it to server. I have tried to open it but not work.
