Fedora Servers :: VNC In FC10 Tweaks - Apple Standard Client Is Slow Over Wifi

Jan 1, 2009

I'm relatively new to Linux, but willing to take a plunge and climb the steep learning curve! I've recently installed Fedora 10 on a spare box I'd like to have running in the lounge by the TV as a TV recorder. Before starting out with MythTV, I would like to get the box running the basics... and hit no major snags with display / audio drivers. I've finally managed to connect to the box via VNC from my macbook over the wireless network. The Apple standard client is slow over wifi, so have started using 'Chicken of the VNC' as the client. At the server end, I intalled vnc-server via yum. I've also tweaked things in ~/.vnc/xstartup so that my default window manager over vnc is gnome.

Fedora Networking :: FC10 - Wifi Devices To Work On 128bit WEP Network - Linksys Wireless-G And 5100AGN

Jun 20, 2009

I'm having trouble getting my wifi devices to work on my 128bit WEP network. I have a new Thinkpad T400, with an internal Intel PRO/Wireless 5100 AGN. I also have some cardbus cards: a Lucent ORiNOCO Gold, a Linksys Wireless-G, and a TRENDnet TEW-421PC. I have them set up as interfaces eth2, eth1, and eth3. (The TRENDnet isn't recognised as a network card at all, so no interface for it.) I have installed the latest firmware for the Linksys card.

The /etc/sysconfig/network-scripts/ifcfg-* files are virtually identical for all of them, differing only in the HWADDR and DEVICE lines. So here's the behaviour:

1. The Lucent card comes up just fine.
2. The internal 5100AGN and the Linksys cards won't come up, and watching with iwconfig shows that they're either associated with my AP OR they've got an encryption key set -- but not both.
3. When trying to bring up the 5100AGN, I get the following messages:

iwlagn: index 0 not used in uCode key table
iwlagn: index 3 not used in uCode key table

/var/log/messages shows DHCPDISCOVER requests being sent, but they're bound to fail since the association with the AP with WEP isn't being completed. And yes, the ifcfg-* files really *are* identical except for the DEVICE and HWADDR lines. The /etc/udev/rules.d/70-persistent-net.rules file correctly maps the interfaces to the MAC addresses. So why does my antique ORiNOCO card work and thew newer ones fail? How can I track down what's being done wrong/not being done?

Fedora Servers :: How To Upgrade From Fc4 To Fc10

Mar 26, 2009

just as the title states i need to upgrade my os from fc4 to fc10 first let me say i have no physical access to the box. all i have is root ssh access to it. So i need to know the best way of upgrading that will be safe. before i do the upgrade the server will be backed up so i will not loose any files. if the upgrade fails the data center will reload the os with what i need on it. but i would rather not have to format.

Fedora Servers :: Tar Backup Of Webserver On FC10?

Jan 27, 2009

I want to backup my apache website using tar. I want to make sure all the permissions and such stay the same so that if I restore a website, it's ready to go exactly as it had been.I am using the following command and would like to know if there is anything else I should neeed to do?

tar --xattrs cvzf backup.tgz /path-to-webserver-files

Now my other question is since tar doesn't store absolute paths, when I run the restore I have to be in the root directory? In another words if I run the command in a user directory will tar do something retarded like encode the paths as ../path-to-webserver or will it just be path-to-webserver so that when I run the restore from the / folder it will automatically go into the right place?

Fedora Servers :: Config For Routing New To FC10?

Feb 4, 2009

So my server running FC4 died last night and I decided to go ahead with the long-awaited upgrade to FC10 while I was rebuilding my server. I use my server for a number of things including, but not limited to: router, firewall, web server, mail server... I have a typical configuration process that I have followed since before fedora, and it has worked well for me up through FC4, but my usual config process doesn't work on FC10.

First of all, I don't want SELinux running, I didn't see an option to not install it during the FC10 setup, so how to I properly disable or uninstall it afterwards? Second, I was unable to even configure the server to route traffic from my internal network to the web, here's the process I usually go through for this:

[Code]...

I don't have a static IP from my ISP, so I'm not quite sure how to add the default route. I think I need to do something like "route add default gw xxx.xxx.xxx.xxx eth1" where eth1 is my external NIC, correct?

What else do I need to do to route traffic? I noticed that I wasn't even able to ping my server from the internal network even though they are on the same subnet, my server's internal NIC has an address of 192.168.7.1 and my computer on the network has an address of 192.168.7.2. If I can get this going to I have internet access again at the very least, I can move forward with the web server, email, etc.

Fedora Servers :: FC10 Hangs On SMB Service?

Apr 16, 2009

I recently setup a file sharing server with FC10 running Samba...

I got it running perfectly and it ran great for a few weeks. I was working on the machine today and tried to reboot it and noticed that it was stuck on FC10's new boot screen. I pressed the esc key and saw that the boot process was stuck on the smb service...

I don't get any errors and the machine doesn't freeze up or anything, it just hangs on the smb service and won't continue with the boot...

Is there anyway that I can get the system to skip the smb service so that I can get into the system? I don't know what's changed or what's causing this sudden hang in the system at boot.

I tried the ubuntu live CD to attempt to go in and edit the /etc/rc5.d scripts to try and skip the smb service start but I am not sure where to look for it...

Fedora Servers :: FC11 Cannot Start BIND After Upgrade From FC10

Jul 8, 2009

I'm having a problem getting BIND to start after doing the FC10->FC11 upgrade. Others have been reporting some bad symbolic links, but this isn't that problem. I've searched the forums here, but I don't see anything like this anywhere.

Here's what I see:

Code:

[root@atomu etc]# /etc/init.d/named start

So, no error message. Logs read as follows:

Fedora Servers :: SSL Apache Non-Standard Port

Mar 21, 2009

I have been struggling with this for the past two days and I can't seem to figure it out.SIMPLE GOAL: use subdomains with my wildcard Rapid SSL cert on Apahce2. This is not a chained certificate.Currently my default SSL virtual host, listening on 443 works fine. So, https://www.myDomain.com is recognized correctly by all browsers. But, the below virtual host listening on port 1025 is not coming across to the browser securely. The page renders, but the browsers do not see it as encrypted SSL.

Fedora Servers :: FC10 Kernel Panic - Stale NFS File Handle

Mar 20, 2009

A FC10 server hung and had to be power-cycled. I suspect it hung because of an nfs mount timeout.

Now it does not boot. The error is libc.so.6 not found. Kernel panic. Attempting to kill init.

Booting under rescue:

ls: cannot access libc-2.8.so: Stale NFS file handle

Is there a way to reboot to a clean state? There must be some NFS cache file.

I also tried to cp rescueCD:/lib64/libc-2.8.so to the old lib64 dir, but get the same "Stale NFS file handle" message.

Software :: Java Really Slow In FC10

Jan 5, 2010

I have a Java application that is used to create PCB layouts called 'DIY Layout Creator'. When I run it on FC10 it is really slow, 7 seconds to render a new object. If I run it on Ubuntu, it works well. I have done some searching and it looks like it is a video driver problem in X windows. FC10 xorg-X11-server is at 1.5.3 where Ubuntu has 1.6.0. FC10 is a the most FC10 version. I tried to update my Xorg to an FC11 version but it fails to install due to dependencies. Other that upgrading to FC12, are there any other options to correct this bug?

Fedora Security :: Tweaks For Storing Information In Ram?

Nov 19, 2010

I've been looking for a tweak that would allow me to store temp and log files in ram. I've found a few that involved editing the fstab file, but they were either Ubuntu articles or they were over a year old and perhaps didn't apply to Fedora 14.I hear there is also a 'noatime' command that can help speed up processes by telling the kernel not to saved when files are accessed.And what are the advantages and disadvantages of noatime, and writing log/tmp files to ram?

Fedora Servers :: Samba Messages In Syslog - Allow Logging To The Standard Samba Logfiles

Mar 18, 2010

I wish to prevent the samba messages (mainly nmbd and winbindd) from appearing in the system log (/var/log/messages). I want to allow samba logging to the standard samba logfiles, but prevent the syslog getting clogged up by samba. I added syslog = 0 to smb.conf and reloaded the config but the messages were still appearing. I also tried the following (and restarted the syslog via /sbin/service syslog restart) # Suppress messages from samba.

nmbd.* /dev/null
smbd.* /dev/null
winbindd.* /dev/null

For interests sake the messages I'm getting are below (I'm not concerned about the messages themselves, I can chase them up at my leisure via the samba logs) Mar 18 09:58:29 SERVER nmbd[3808]: query_name_response: Multiple (2) responses received for a query on subnet xx.yy.z.zz for name DOMAIN<1d>.

Fedora Servers :: NIS Server / Client - MD5 Password Different

Dec 26, 2010

I have FC14 running NIS master and the Solaris 10 (192.168.0.10) client is able to use authenticate. However, when I try to change the passwd (via yppasswd) on the Solaris host it reports "Permission denied".

On the FC14 host, the syslogs show that the passwd is invalid:
Code:
Dec 26 22:09:49 linux rpc.yppasswdd[2031]: update test (uid=502) from host 192.168.0.10 rejected
Dec 26 22:09:49 linux rpc.yppasswdd[2031]: Invalid password.

The Solaris host has been reconfigured to generate md5 passwds and the linux host the same (via authconfig). Indeed when I set a local user's passwd on the Solaris host, the passwd (the shadow entry) looks like a MD5 passwd (starts: $1). I don't know if this is related to my NIS problem, but when I generate the SAME passwd on linux, the shadow entry is different.

C. I cannot for the life of me figure out how to get a mac OS X 10.6.5 clientto work.

The closest I got was setting up Cups from the apple client, and printing a test page from the CUPS webpage. Nothing else.I have tried just about everything, forwards and backwards.I get almost always the same result.My printer pauses when I try to print to the server -- I hit resume, it pauses. It just doesn't complete a single job.

Fedora Servers :: Can't Login Remotely To Client Machines?

I am running NFS and NIS servers in my FC8. Clients are also running FC8. Everything was working fine. I could login remotely to server as well as clients. Suddenly (few days ago) a problem started. I can not login remotely to client machines. I did not do anything. I can login to server remotely, but not the client. When I try to login, it accept password and nothing happens. Also, when I try to login from server to client same thing happens. We share the home directory of the server with client. Another question: there two type of nfs server nfs-user-server and nfs-kernel-server. I just use gui to set up the NFS. I don't know which one I am running. Is there any way to find out which nfs I am running?

Fedora Servers :: Failed To Mount Share On Client

Setting of my NFS as following and I am failed to mount client and get connected the both computer using Fedora 11; server ~(tower) and client (note book)

NFS Server setting ...

After making several attempt I cannot mount share on client. What I am missing here? OR is there problem with F11 with NFS server? While throwing everything including sink... I ran tcpdump on server while issuing mount command from client; I got following tcp dump.

Fedora Servers :: SQUID Slow / Debugging It?

Apr 30, 2010

I have squid running on F12 fully updated. Pretty much stock config except bigger cache size.

Over time it seems to start lagging and occupying more memory. Currently using ~400Mb after a couple of months. I'm sure its causing some lag / refreshes because if I turn if off and go direct to internet the same site I had to hit refresh on, loads instantly.

Going through the logs in /var/log/squid I don't see anything suspicious with the untrained eye, whats a better way of debugging it to see where/why the delays are happening? Its a single user setup (for fun really lol) so theres a lot of misses in access.log. cache.log just has a handful of bad img headers which does not line up with lagging websites.code...
