CentOS 5 Server :: TFTP-server Unable To Send Files To Clients Outside It Subnet?
Sep 9, 2011I have tftp-server running on Centos 5. Clients which are on the same subnet as the server are able to get and put without problems. I have a client that is across the internet that is having trouble getting files from my tftp server. A tcpdump reveals that the client is requesting the same file over and over again. In /var/log/messages, I am see the following error repeated over and over until the client finally gives up.
localhost in.tftpd[12727]: tftpd: read: No route to host
Ubuntu Networking :: VPN Server Does Not Allow Clients To Access Internet?
Jan 7, 2010i have successfully setup PPTPD on my server and I can open a VPN tunnel but my clients can only ping the server's IP, they don't have access to the internet through the VPN.
i have searched different forums and understand that I have to create a route on the server to route packets between the VPN interface and my internet gateway, but I didn't manage to get this work.
here is what my setup looks like:
Code:
root@r31495:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:1c:c0:c7:13:35
inet addr:94.23.197.XX Bcast:94.23.197.255 Mask:255.255.255.0

General :: Iptables Rules To Allow Nfs Clients Access To Nfs Server?
Jan 20, 2011I'm curious but recently I was troubleshooting some iptables rules to allow nfs clients access to my nfs server. What was strange was that I setup a tcpdump session on my nfs server so that I can see which ports were being requested. I ran several tcpdump sessions with the following filters in place.
tcpdump -vv src ip_of_client and dst _ip_of_client
tcpdump -vv src hostname_of_client and dst hostname_of_client
However, the only packet I ever saw come over the wire to me was the client host asking for a arp resolution. Anyhow, I finally just ran 'rcpinfo -p' and added those ports to my iptables rules and it worked great. However, I would like to understand how nfs works in case I need to troubleshoot it in the future. I do understand that nfs uses portmappers, would this explain the behavior?
CentOS 5 Networking :: Can't Seem To Get The X Server To Allow Access From Clients On Other Hosts?
Jan 8, 2009I can't seem to get the X server to allow access from clients on other hosts. (I know, not exactly a network problem, but. I made the change in /usr/share/gdm/defaults.conf to be : DisallowTCP=false
and this worked on another CentOS system, but it hasn't fixed it on this one. What other things could prevent other clients from connecting to the X server? From the local host, I get :
Warning: Tried to connect to session manager, Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed although the client DOES actually create the window and work! So, maybe this message is a clue.
From the remote host, I get : Error: Can't open display: 10.10.1.20:0.0 Which is not terribly informative. Is there a log somewhere which details why a connect request was denied? The files in /var/log/gdm are not very informative.
Server :: Allow Wireless Clients Access To Network Based On Their MAC Address?
Jan 11, 2011Using CentOS 5.5, FreeRADIUS 2.1.7.
Objective is simply to be able to allow wireless clients access to my network based on their MAC address (I have about 10 WAPs around the country which I need to be able to manage user access centrally). Not interested in LDAP or dishing out keys/certificates etc.
I have been trying to follow the guide here. Sounds like it's exactly what I need but I'm not sure about a few things.
1) For each of the conf files am I supposed to be replacing everything currently existing in the respective file with what is suggested?
2) "raddb/modules/file" does not exist, so I assume I should use "raddb/modules/files"?
3) If I uncomment the line:
Code:
#rewrite_calling_station_id
under the "raddb/sites-available/default authorize{}" section, the radiusd startup gives me the following error:
/etc/raddb/sites-enabled/default[69]: Failed to find module "rewrite_calling_station_id".
If anyone familiar with FreeRADIUS 2 could answer these queries I might be on the right path
Ubuntu :: FTP Clients Can't Download Files From My Server / Fix It?

CentOS 5 Server :: NFS Clients Not Seeing All Files In Export?
Dec 9, 2009We recently upgraded our NFS server from Centos 4.4 kernel 2.6.9-42.0.10.plus.c4 to Centos 5.4 kernel 2.6.18-164.6.1.el5
In our queue directory where we shuffle files to be processes some files will go missing.
Example structure
/Queues/Process1/subdir_xxx
/Queues/Process1/subdir_xxx
etc...
/Queues/Process2/subdir_xxx
/Queues/Process1/subdir_xxx
etc...
Where 'xxx' is a date/time string down to the second.
Each subdir entry contains a number of files, depending on load at the time.
What we see happening is that a subdir will appear empty from a client (ls -la shows . and .. ) but an rmdir will fail with a 'directory not empty' error. From all 7 clients (mix of Centos 4 and 5). However on the server the files are visible. If we 'touch' the files the clients will then pick them up and process them.
It doesn't appear that waiting any amount of time will make the files visible (we've waited 8 hours while testing).
We've tried different mount options, NFS4, etc. Nothing got rid of the issue. Changing one server to use CIFS however solved it. So it appears to be some bug in NFS.
The problem appears to be intermittent and random, we can go hours without seeing it, or minutes. I'd say it affects fare less then 1% of the files written.
General :: PPPOE Server Access Internet Clients Fail To Access Internet
Aug 26, 2010I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?

There are many many more lines similar to this but its obvious that a remote host was attempting to run my phpmyadmin page and gain access. My question is that since I'm a novice at running httpd what sort of things should I be looking out for in regards to security and configuration to prevent any attacks or is this common and should just be ignored? I do run phpMyAdmin on the server and have configured MySQL to not have blank passwords or user accounts. The database had no new changes to it so I doubt they actually accessed it.
Ubuntu Servers :: Access To Web Server Files ?
Jul 24, 2011I'm new to Linux and have taken over at a company where the linux admin walked out. he has several older linux based servers running version 8.1 i tried running the command sudo apt-get install swat xinetd to setup swat but i get an error that it can't find the package. in addition, this directory xinetd is no where to be found under the etc directory. i've verified that samba is in fact installed on these servers but for some reason the xinetd and inetd directories are not on these servers.
Could it be possible that this older version of linux does not support Swat? i'm considering upgrading very soon to the latest but my main problem right now is i need to copy all web server html files that he had on the web Server i know there are different ways to copy files from linux systems but need the best way to copy all the files so none of the website links get broke off this linux server over to my windows server.
Since i don't have access to anything of the directories nor files on the web server, what is the best way to copy these files and folders off this server?
