General :: Clean /var Storage On Dedicated Server?

Feb 4, 2010

The /var directory is 97% full on my dedicated server:

I would like to know if it is safe to clear it and how to clear it (assuming it will not disrupt/kill server services to do so).

I have Matrix control panel so i can view the storage etc but it does not have an way of clearing the /Var directory.

I have Putty Access to root but do not know which command to use.

I found a few threads but the information is not clear to me as there seems to be an assumption of basic knowledge I don't yet have.

My linux/ubuntu support that usually does this kind of thing for me is away and not contactable and my server is grinding to a halt and unable to store/send email.

I have only a very basic understanding of command line but really need to get this sorted ASAP.

General :: Home Media And Storage Server?

Jun 2, 2010

i have a spare computer and 4 hds and was planning to make this computer a storage server with a media place aswell... i do have some linux knowledge but never used it for this and am not sure how good it will be initially the media files are in an HD with ntfs format which i want to keep as is... but i was wondering what options i had to make a media folder over network where i could browse and watch from any computer in my network ? is it samba my only options or is there a more media like solution for this ? There will aswell other features i was planning to use on it which made me think of linux, for example, svn server, websever with mysql to testing my applications, connection manager, all these i am sure on how to make and setup... but i am not very familiar with samba hence i am not sure if it is the best options for file sharing aswell as media sharing and/or my only option.i also heard that ntfs might be trouble some for linux in some cases

Server :: VPN Setup - Dedicated Or VPS / Bandwidth?

Jul 10, 2011

I want to rent a (root) linux server to run a vpn service on it. I want to allow people to use this vpn.

My questions are as follows:
- What kind of server/service should I rent - dedicated or vps?
- Is one IP-Address enough to connect, say, 100 user? (I plan to run IPsec or OpenVPN, maybe PPTP)
- What Bandwith and/or traffic limits I need to consider to make the service reasonably fast for the users?
- Which Linux-distro should I use? Ubuntu Server, CentOS, FreeBSD, Debian etc?
- How much RAM and HDD space is recommended for such an endevour?
- Any advice on the processor type the server should have?
- Is 100M network ok or better 1000M?
- What means 100Mbps shared bandwidth in contrast to 10Mbps dedicated guaranteed per server?

General :: Win Storage Server 2k8 Share To OpenSUSE 10.3 - NFS Preferably

Jul 20, 2010

My Goal: I'm migrating data from the OpenSUSE server to the 2008 Storage Server. The idea is that all the data will reside on the 2008 Storage Server in an NFS share which will be mounted to the OpenSUSE server in the same location in which the data sat in initially.

I'd like this to be completely transparent to everyday use -- all programs designed to interact from a few other servers / computers will still work without modification, and, more importantly, all file permissions can remain the same. As far as I've seen the SMB mounting doesn't full preserve the *nix file permissions. I'm hoping the NFS mount will, but please tell me if I'm wrong. SMB is so much more straight-forward and already working. I should also note speed is a giant plus for NFS.

The Players:
Windows Server 2003 - The Active Directory server
Windows Storage Server 2008 - The new file server
OpenSUSE 10.3 - The workhorse server

I have no control over the operating system choice. I have no control over the AD server. I have limited, intermittent access to the person who does have full control of the AD server. I have full control over the file server and the workhorse server.

What I've done: The Storage Server is running Services for Network File System (NFS). It has a 6.5ish TB RAID partition configured for NFS and Samba/CIFS sharing which is used for the data storage. The Samba/CIFS share is mountable and accessible, but I haven't found a way to maintain proper user permissions on the files. When I connect the owner and group for every file is root:root, which led me to NFS in hopes this would fix the problem.

The AD server admin has installed Services for Unix, and we imported the OpenSUSE passwd and group file. Either this didn't work, or it take a bit more configuration. Tomorrow morning we're going to take a deeper look into the SFU configuration with the AD.

Right now I can mount the NFS share on the OpenSUSE under the root account:

Command results truncated to what I think is relevant info. Ask if you need more.


My Problems:

I'm hoping the "Permission denied" error is solely because the UID and GID mappings are incorrect. I have, however, tried to create an NFS share with full permissions to "Everyone" and anonymous access, and I get the same results.

Also I've run into another roadblock. Why do non-root accounts fail to execute the mount /mnt/datadir command?


AFAIK 1048 is not a restricted port, so regular users should have access to bind to the port. I also have a Gentoo machine where regular users are allowed to execute the command. The 'mount' command shows that the NFS share was mounted with the username executing the command too.

Server NFS Config:


The following are the settings on localhost

The above was written yesterday and not posted in hopes I could solve the problem this morning. I failed.

Update: The domain admin installed an NIS server on the AD server. I installed an NIS server on a Gentoo Linux box. They weren't able to communicate. The Linux box thought the Windows NIS service wasn't running and Windows couldn't find the Linux machine. NIS led to a dead-end right about there. I also tried to manually link the user accounts to UNIX UIDs via the AD user properties window to no avail.

Server :: Clear /var/cache/apt/archives On My Dedicated ?

I found a few threads but the information is not clear to me as there seems to be an assumption of (basic?) knowledge I don't yet have.

Is it possible and SAFE to delete files via FTP from the /var/cache/apt/archives?

OpenSUSE Network :: How Does A Server Without A Dedicated Monitor Work

Mar 29, 2011

When you need to change something on the server you can hook up a monitor and a keyboard and do it through the console.

I would like to hook up an external monitor in this fashion for a desktop. The current video card can only support a single display. So I was hoping there was someway to use a second monitor as just a permanent console since simple text shouldn't require a video card?

Networking :: Routing Incoming Traffic To NAT'ed VM On A Hired Dedicated Server?

May 21, 2010

I have set up a Virtual machine on a dedicated server from 1and1. I hoped to use a bridge to give the vm direct access to the internet but 1and1 do mac filtering and so the only option is to use NAT.

I used Virtual Machine Manager on my Ubuntu 10.04 machine at home to install Debain Lenny on the vm on the server using KVM and all went well. I put it on a virtual network and i can access it from the host and i can access the internet from the guest using NAT that libvirt set-up.

I bought another ip address from 1and1 with the hope of forwarding packets to the new ip address to the guest vm.

I have tried all sorts of routing rules using iptables without any success.

my virtual network is on virbr1 the guest ip is my external network device is ip say on eth0 with the secondary ip say on eth0:1

Here are the latest rules i tried:


iptables -t nat -A PREROUTING -d -i eth0 -j DNAT --to-destination
iptables -t nat -A POSTROUTING -s -o eth0 -j SNAT --to-source
iptables -A FORWARD -p tcp -i eth0 -o virbr1 -d -m state --state NEW -j ACCEPT
iptables -A FORWARD -t filter -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT

Ubuntu Networking :: Set Up Dedicated Server For Source Games - Port Closed?

Jun 23, 2011

I am currently having an issue attempting to set up a dedicated server for source games (TF2, CS:S, L4D2). The required port (27015), along with most others, appears closed to the rest of the world and upon a port scan with DMZ hosting on (therefore no router interference between the internet and my computer) only a few ports are open (80, 139, 443, 445). My ISP does not block ports so therefore the only issue I can find is with my computer running Ubuntu 11.04. I have ensured that all traffic is allowed via iptables and I can't think of anything else that would have ports closed.

Server :: Access The Servlet Engine's Web GUI Just Fine Over Its Dedicated Port Via Browser?

Nov 26, 2010

Been a while since I last posted here, though I stop by often. Unfortunately I find myself in a bit of a pickle again. Here's the situation. I have an RHEL3u5 server running Apache 2.0.48 and an equivalent of Tomcat and JBoss. IBM's WebSphere Application Server 6.0.2 to be exact, the Apache also being one of their flavors (IBMIHS).

Everything's been going dandy since forever, but lately the httpd processes seemingly just hit a brick wall of some unknown kind. Checking the /server-status page reveals a whole lot of piling up "waits".

The funny part is that the load average rarely goes higher than 1.0, I/O seems within limits, memory usage as far as I can tell seems fine, disk usage appears all good... I would've felt more at ease if something did shoot through the roof, but there's just nothing to go on. It's definitely Apache getting its knickers all in a twist as well since I can access the servlet engine's web GUI just fine over its dedicated port via browser.

Here's what I noticed so far: Apache processes rise steadily to over 35 or so, after which it all goes south fast. As a result and as a temporary fix, I've enabled a cronjob that checks the amount of httpd processes and just restarts Apache if they're above 28. So far this seems to keep things sort of happy, but obviously I'm still twitchy with the overall state of affairs. I do not have the settings immediately at hand, but here are some further details so far:

Server spec:
8 x Xeon CPUs

I'll post further details probably on Monday, specifically key portions of the httpd.conf file.

General :: NFS Failover - Setting Up Two Server With Shared Storage With Automatic Failover If One Fails

Feb 14, 2010

What is the current state of NFS failover (i.e. setting up two server with shared storage, with automatic failover if one fails?) I've seen a cookbook, but no details that would let me assess how well it works. There are lots of complex issues with data consistency, but the detailed information on that is years old. Our needs are fairly simple: 2 servers, a shared array, and I'm reasonably sure that we don't use locking. However we'd like failover to work reliably without loss of data.

General :: Adding Memory From Dedicated Kubuntu Partition Back To Vista

Jan 16, 2010

I decided to remove my Kubuntu partition until I can fully dedicate my time to figuring out linux (right now I need Windows for certain things, i.e. flash and my zune).

I fixed the MBR, but the problem now is I have a 142.77 GB partition of free space. What do I do? Do I just delete it?

When I click delete this is the message I get:
"This is an Extended partition. This partition will become inaccessable if you delete it. Are you sure you want to delete this partition?"

I am essentially asking if this just means the partition will be gone and not the memory, and where the memory goes if I delete the partition.
