NFS client firewall config?
by Rudi Ahlers 20 Feb '10

20 Feb '10

Hi all, Which ports do I need to have open on an NFS client's firewall to allow it to connect to a remote NFS servers? When I disable iptables (using ConfigServerFirewall), it connects fine, but as soon as I enable it, NFS gives me this error: root@saturn:[~]$ mount master1.mydomain.co.za:/saturn /bck mount: mount to NFS server 'master1.mydomain.co.za' failed: RPC Error: Unable to send. I have added ports 111 & 2049 in both the TCP & UDP ingres & exgress ranges, but that doesn't seem to help. portmap & nfs is running as well. But as I say, as soon as I disable the firewall, it mounts fine. Google search results reveal a lot of different ports, like 4000:4004, 83xxxx (something, I forgot) but it still doesn't help. root@saturn:[~]$ rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100021 1 udp 48996 nlockmgr 100021 3 udp 48996 nlockmgr 100021 4 udp 48996 nlockmgr 100021 1 tcp 47195 nlockmgr 100021 3 tcp 47195 nlockmgr 100021 4 tcp 47195 nlockmgr 100011 1 udp 4004 rquotad 100011 2 udp 4004 rquotad 100011 1 tcp 4004 rquotad 100011 2 tcp 4004 rquotad 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100003 4 udp 2049 nfs 100003 2 tcp 2049 nfs 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs 100005 1 udp 4003 mountd 100005 1 tcp 4003 mountd 100005 2 udp 4003 mountd 100005 2 tcp 4003 mountd 100005 3 udp 4003 mountd 100005 3 tcp 4003 mountd -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

CentOS and Bash History
by Robert Spangler 19 Feb '10

19 Feb '10

Hi, I was wondering if bash or inputrc has changed form CentOS v4 to CentOS v5? Reason I ask is at the bash cli I can type, for example 'su' and then with the up and down arrows I can scroll through my history and will only see the commands that begin with 'su'. In CentOS 5 this isn't the case. I have added some code to my inputrc file to make this work in CentOS 4 as follows: # Search History for previous used commands "\M-[A":history-search-backward "\M-[B":history-search-forward "\M-[C":forward-char "\M-[D":backward-char And this works well in CentOS 4 but I cannot get it to work in CentOS 5. Anyone know why or what I have to change? -- Regards Robert Linux User #296285 http://counter.li.org

Resizing a PV that belongs within a Volume Group?
by Eric B. 19 Feb '10

19 Feb '10

Hi, I was wondering if there was a way to extend (ie: grow) a PV that is part of a Volume Group? I currently have a partition on my HD that is being used as a PV for my Volume Group, but would like to make it larger. I have the space on my drive to extend my partition, but using standard tools (ex: gparted, Partition Magic, etc) would likely end up corrupting the data on in the Logical Volumes that are housed within the VG. I realize that I could just create a new partition on my HD and just add it to my Volume Group and extend my Volume Group, however, given that it would be two contiguous partitions on the HD, I was just wondering if there was a way of resizing the original partition within the VG without causing any problems. I tried looking at tools like pvresize but I can't seem to understand the right arguments to use it as whatever I try never seems to resize the original partition itself. I also looked at system-config-lvm GUI tool, but that doesn't seem to allow me to make the PV any larger. Does anyone have any suggestions? Thanks! Eric

best practice: how to setup a central "network installation server"?
by Rudi Ahlers 19 Feb '10

19 Feb '10

Hi, I want to setup a central installation server, but haven't done this before, so I want to find out what would be best practices for this? The server I have already runs as a central repo, which is updated from one or our local centos mirrors, and the other CentOS servers (both i386 & x64), as well as CentOS VPS's get their updates from this server. But, now I want to allow a client to perform a quick network installation, using either a netbood CD, or preferably with the server's network bootrom. I understand this can be done with bootp, or am I on the wrong track? the server is a general file server and also acts as our in-office internet gateway, and has Webmin installed for convenience sake. I don't know if this is of any use? Generally we would be (re)installing CentOS servers & desktops, but I guess it could be useful for other distro's like Fedora Core / Debian / FreeBSD? / etc. What would be a good option to go for, or could someone point me to a good documentation? Doing a google search I found a lot of instructions on how to perform a network installation on the client PC's, but not how to configure the server. Maybe I used the wrong key words? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Dependency problem with yum-utils when installing Cobbler on CentOS
by Marcelo M. Garcia 19 Feb '10

19 Feb '10

Hi I'm trying to set up a Cobbler server, and when I run "cobbler check", I got the following message: The following potential problems were detected: #0: yum-utils need to be at least version 1.1.17 for reposync -l, current version is 1.1.16 [root@tannat ~]# I'm using Cobbler 1.6.6-1, CentOS-5.4 (x86_64), and (as the message says), yum-utils 1.1.16. Is there a way to fool "Cobbler check"? Thanks Marcelo

Server HD failed and I think I am hosed
by Slack-Moehrle 19 Feb '10

19 Feb '10

a hd in my server failed. I noticed when I went to SSH in and get a copy of some files in /var/www/html I tried to tar the files and I was told No, read-only file system. I restarted and tried running FSCK manually (without -a or -p) and I get inode errors, short reads, etc. I tried booting to my CentOS 53 install DVD. I do linux rescue and I get to where it wants to know where CentOS images are. I select local CD-ROM and it just spits it out at me and tells me to try someplace else. Even though I booted from the CD! I am not sure what else to do. I dont think I can mount this on my macBook to do anything. But I really need just the data from /var/www/html. I have a backup that is a week old, but I know changes were made late last week that I would like to not have to do again.... Where is my backup of the changes I made? Well my SSD drive failed in my laptop and I dont think I have them... Can anyone provide advice as to what to do next? Also, what would have caused this all of the sudden? This box has been running fine for months.

Dear All, We are running RHEL4 Update 4 AS IA-64 on a HP rx6600. We are running programs compiled in RHEL4 Update 4 AS in i386 architecture using the emul library(Intel IA-32 Execution Layer ) [admin@corviewsecondary ~]$ service ia32el status Intel IA-32 Execution Layer in use When we attempt to run a program using /usr/bin/gdb we are not able to hit the break point set.

How to run a i386 compiled program in IA64 bit environment using gdb and be able to hit break points? 2.How do we catch a running process in gdb and apply a breakpoint in our setup. The code of C program in question is given below #include <stdio.h> int count=0; void printString(); int main() { printf("unlock\n"); while(1) { //do nothing printString(); //break; } return 0; } void printString() { count++; printf("count = %d\n",count); return; } The above c code compiled in i386 environment and the IA64 bit server in which we are running this program are attached. Thanks in Advance, -S.Balaji
