Anyone had issues when logging into a server that is running vsftpd such as when you go to connect and it never lists the directory or anything but just says connected and just hangs? -- Andrew Rice Jr

Two ethernet adapters and more
by Robert Moskowitz 26 Jan '06

26 Jan '06

I am running Asterisk@home on one of my systems here. It uses Centos 4.2. It does NOT have a GUI interface. Command line only at console or via SSH (yeah, I know that I was working on another server to get GUI tools working through SSH, but I am NOT going to muck with AAH build). yum update is potentially dangerous, when it replaces the kernel. You can loose all of your Zaptel driver setups and have to rebuild them. This is a given, the first time you install AAH and run yum update.... Now at http://www.voip-info.org/wiki/view/Asterisk%40Home+Handbook+Wiki+Chapter+3 I was instructed to use NETCONFIG to setup up my network information. Well it did for eth0, but not for eth1. So question #1 is how to use netconfig to setup eth1 without messing with eth0. #2) NETCONFIG did not setup my hostname and domain. I had to go in with VI to resolv.conf and sysconfig/network. Is there a tool for this? #3) How do I figure out which board is which. Other than looking at the MAC address and using PCISNIFFER to then relate that to one of the boards (well, one 'builtin'). Also how do I determine which board is using which IRQ. #4) Finally how can I change which IRQ a board is using. As one of the boards is using the same IRQ as one of my Zaptel clone cards (Tigerjet chips according to PCISNIFFER). #4 leads into the 'more'. This system has TWO FXO clone cards. One is working in AAH, the other AMP does not see. Asterisk CLI flags one as "alarm" RED. and does not report the IRQ of either board. #5) How do I figure Centos has configured these two cards, and what IRQs are used and maybe how to change the IRQs. #6) Then how to get genzaptelconf to properly configure this card. Barrs Law of Recursive futility If you're smart enough to use one of these.... .....you can probably manage without one!

Hey I was just curious if anyone knew of any scripts or command line programs that are out there that could be used to check bandwidth on a network. -- Andrew Rice Jr

centos 4.2 (32bit) app installed on (64 bit) box mising library
by Jerry Geis 26 Jan '06

26 Jan '06

I have a centos 4.2 32bit app that when installed on centos 4.2 64 bit box and try to run it I get "libxml2.so.2 not found". however if I "rpm -qa | grep libxml2" it shows up just fine. How can I get this app to run on the 64bit box (without recompiling yet). The recompiling will come someday... right now I just would like it to run. Thanks Jerry

freenx in rootless mode and session resume anyone?
by Sophana Kok 26 Jan '06

26 Jan '06

Hi I suceeded to run freenx on centos3 with the nomachine client, but I still have some issues. First I can only get a new whole desktop (kde) session. I cannot resume it, and it always leave tons of process that I have to kill from root. I don't need the whole kde desktop, and only want to have single windows. This is called the rootless mode I think and cannot make it work, it simply hangs. Finally I succeded in running the nxagent and nxproxy manually in rootless mode, but the problem is that I have to do this on my linux router (I use x.org from cygwin). but there is no nxproxy on windows or cygwin I think. Is there a way to run single windows with the freenx client and resume sessions? Thanks.

Virtualization
by Bards1888 26 Jan '06

26 Jan '06

Hello all, I looking at setting up some virtual servers on my centos 4.2 x86_64, mainly just to play with the technology. I tried the latest openvz kernel (kernel-022stab061.1-released) on my centos 4.2 x86_64. It booted no problems and in the main did not seem to slow the machine down (which is nice), all my drivers worked, Raid1 is built into the kernel as opposed to a module for example. There were a few issues namely 1) that kernel does not seem to have nfs support compiled in 2) it cannot loopback mount ISO's and 3) there are no vzyum rpms for x86_64 which basically means you cant build your own templates, if I read it correctly. Anyways, I'll get to the point now... does anyone have openvz 64 bit or 32 bit running on centos, or does anyone have xen 3.0 running on centos ? I'm keen to hear peoples experiences and tips if they have any. Cheers. Bards.

RE: [CentOS] Ext3 filesystem access after downgrade from v4.2 to v3.6 [SOLVED]

A v4 filesystem shows these features # tune2fs -l /dev/sda1 | grep features Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery sparse_super large_file A v3 filesystem has these features # tune2fs -l /dev/sda5 | grep features Filesystem features: has_journal filetype needs_recovery sparse_super Tunes2fs from v4.2 can be used to remove "has_journal filetype dir_index sparse_super" Booted into rescue mode with a v4.2 cd and removed dir_index but the v3.6 OS still complained. After finding this link https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=145307 which references problems with ghost and v4 ext3 partitions I used debugfs to remove some of the other 4.2 specific features. # debugfs -w /dev/sda5 -R "features ^resize_inode ^ext_attr" # fsck -y /dev/sda5 The v3.6 OS now boots correctly.

prompt to overwrite when re-saving file in MS-Excel to samba server
by Matt Morgan 26 Jan '06

26 Jan '06

I have a couple users, in a new install of a samba file server on CentOS 4.2, who are being prompted to overwrite the existing file when in MS-Excel and simply saving the active spreadsheet. Normally, File--Save (or just clicking on the disk icon) for an already saved file will re-save the file without prompting to overwrite. I have my doubts about whether this could be a server-side issue, and suspect it's probably Excel, except 1) it started when I switched them from a Windows file server to the Samba server; 2) it happened to both of them at the same time; 3) I've been working with Excel for a long time and never seen a setting for this. Anybody have any idea what this could be, or how to diagnose it? Googling gets me a few VBScript questions, nothing useful. FYI, the samba share is pretty basic, but I did increase the create mask and directory mask settings, since these files are shared between several users and they need to write each other's files. Apart from that, no deviations from the norm. Thanks, Matt
