I've got a problem with squid_radius_auth. Each time squid tries to authenticate, it sends incorrect password. Somebody already asked this here on LQ, he had incorrect shared secret set... but I'm quite sure the secret is correct, yet it cannot authenticate. /usr/local/squid/etc/squid_radius_auth.conf

I cant figure out why my server running fc14 keeps saying login incorrect 530. I am using gproftpd. I know that the login is correct though. For instance:
Lets say my user is "goober" and my pass is "fedora" and I go and type that in when I try and login to the ftp it says login incorrect.
One of my servers is displaying the error as login incorrect even after giving the correct password. Once I restarted the Virtual Machine and after that it is accepting the same password to login. I am not able to find out the problem, why the server is not able to validate the password until the virtual machine gets rebooted.

I am fairly inexperienced as far as Linux is concerned, so if anybody could tell me how I could solve this.
I am attempting to connect to VSFTPD via Filezilla from a windows machine, but regardless of which user name I use I get a "530 Login incorrect" error. I have tried turning off the firewalls on both the CentOS and Windows side of things with no result. I disabled the SSL/TLS commands in the config file, also with no change. I tried a couple of different FTP clients, but got similar results regardless of which client I used. I have been going over man pages and documentation for a couple of days now, but cannot come up with an answer. I suspect it lies in my configuration, but I got the same results when I reverted my config file back to the original. what else I can do? One other note is that I am attempting to connect via a LAN, at this point I don't care if it works across the WAN as I only intend to use it to upload files to my web server.

View 2 Replies View RelatedLast week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.

I have configured openssh 5.8p2 with centos 5.6. My sftp is working fine with chroot environment but i am having problem with SCP. I am dealing with muliti Redhat servers. When i try to transfer data from other linux server through scp it gives connection refused. For e.g ssh 5.8 is configured on new server and i want to transfer files from old server which is using openssh 4.3 version.i created same username and password on new server as on old server.My sftp users on new server has no shell access but only sftp access. When i try to scp from old server to new server it gives error connection refused. Is the below configuration only for sftp and can't scp? According to google the configurations i found are for scp and sftp. Do i need to generate ssh keys by giving users on new server shell access, once created then stop shell access again, as i dont want to give shell access permanent for security reasons? but i want to use ssh keys for more security as well.

I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/)Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?

View 6 Replies View Relatedwell, I have a redhat 9 server. it has a separate hdd mounted as /backup where I always used to take the backup tar files. Now I am planning to upgrade it to CentOS 5.5 Easy job. except that I want to keep the hdd same way for backup. And ofcourse without loosing any of my existing data.
Means, the current hdd i want to again use with keeping the data because I have to restore the whole thing just from that HDD and again that will be used for the backup also like before...
so advice on adding a new HDD without loosing data. And opps, the current backup HDD is accessible through /backup and I want to keep that too... but it is not a symbolic link... here is my current /etc/fstab
Code:
LABEL=/ / ext3 defaults 1 1
LABEL=/backup /backup ext3 defaults 1 2
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0

I have a php script that creats some files and moves them into certain directories. When the files are created, the ownership is www-data:www-dataWhen they are moved to the appropriate directories the maintain that. But, I need the files' ownership to be changed to asterisk:asteriskHowever, www-data doesn't have permissions to do this. I don't want to run a cron as root that does this (I'm already doing that). I really wish there was a way for my files to be created via my php script and in that same file do something like:
system("chown asterisk:asterisk /home/test/test.call");
this is my fstab::

LABEL=/ / ext3 defaults 1 1

Now while installing, I had 2 Hdds. at the time of partitioning, i used both as separate Hdd and made a /backup. I used that for my backups. That was RH9. Now I want to install Centos 5. and i wish to keep the /backup as it was. (as my cron scripts and others are written in this way)I wish that it will be mounted at the time of boot. And moreover, I can add a new hdd (using the manuals) but I need to keep the data.
Also the second question:: I have implemented a WiFi hotspot in a hotel with a Cisco WLC and several Cisco APs. Now I wish to restrict and log on access for both wifi and wired LAN using user names. Raduis is okey... with a mysql password database... I found a thing named hotex hotspot billing. But that's expensive. Also FCS's module is expensive too. I do not need billing, just access control. Any ideas on this?? It must be a linux based kind of baremetal package...
My rsync takes backup of everything from the differenct linux servers to my backup device which is 2 TB only .Since it takes almost full backup of source , it consumes space lot in the backupdevice. So i wanted to keep all my backup files of one month old latest files in backup device, it should remove all files more than one month data.

View 5 Replies View RelatedI have an Apache 2 server setup in Ubuntu 10.04 LTS on my lab computer. The server listens on port 80, by default. I also have another process listening on port 4000 - this is a special server that executes some Matlab and other application scripts. However, due to university policy (or some licensing/faculty regulation - not really sure), this port 4000 has been set as one that listens only to the localhost. Now, we need to allow a few of the scripts to be run by people remotely.
We tried to setup a web interface - they enter a few values into a HTML form and submit. This form has action="URl... (basically, we were hoping the external form turns data over to the internal form), thereby keeping everyone happy. However, it turns out that this didn't work - the server on port 4000 realizes that the request isn't internal.
What would be the best way of handling it? While we did consider port forwarding, we didn't want everything to be accessible from the internet - i.e. we wanted a tightly controlled interface when accessed from outside, but if someone writes a program on localhost, we want everything to go through as normal (i.e. the current setup). Is there a way to do this without duplication (i.e. setup a new port 5000, that has only the components we want the external users to access)?
