question on alias IPs using ifcfg-eth0:x
by Ray Leventhal 14 Sep '07

14 Sep '07

When using ifcfg-eth0:x files in /etc/sysconfig/network-scripts/, should each file (where x increments appropriately) point to DEVICE=eth0:x or DEVICE=eth0:0? I apparently have my alias files all ifcfg-eth0:0 - ifcfg-eth0:7 show DEVICE=eth0:0. Is this right? It seems odd to me and while it does seem odd, the alias IPs are being appropriately responded to, answering pings and nameserver requests. The output of /sbin/ifconfig is what clued me in to the fact that I may well have done this wrong. This output showed eth0 and eth0:0 only. Suggestions are welcome and much appreciated. Thanks, ~Ray CentOS release 5 (Final) 13:28:59 up 40 days, 1:58, 1 user, load average: 0.00, 0.03, 0.00 kernel: 2.6.18-8.el5

centosplus kernel question
by Mark Foster 14 Sep '07

I noticed a new upstream kernel was released yesterday and now wondered how long until the corresponding version of the centosplus kernels are updated? https://rhn.redhat.com/errata/RHSA-2007-0705.html -- Said one park ranger, 'There is considerable overlap between the intelligence of the smartest bears and the dumbest tourists.'

[CentOS 5] tftp-server, unable to create new files (even with "-c" option)
by Davide Grandis 14 Sep '07

14 Sep '07

Hi all, I'm trying to setup a TFTP server to serve as repository for the config of all my Cisco network devices. As per the the tftpd man, I've added the "-c" option into the /etc/ xinetd.d/tftp (as follows) but I still cannot get write access (unless the file is already present). [root@chl1 ~]# cd /etc/xinetd.d [root@chl1 xinetd.d]# cat tftp # default: off # description: The tftp server serves files using the trivial file transfer \ # protocol. The tftp protocol is often used to boot diskless \ # workstations, download configuration files to network-aware printers, \ # and to start the installation process for some operating systems. service tftp { disable = no socket_type = dgram protocol = udp wait = no user = root server = /usr/sbin/in.tftpd server_args = -s -c /tftpboot per_source = 11 cps = 100 2 flags = IPv4 } And here is it concerning the home path owner & permissions: [root@chl1 /]# ls -la ... drwxrwxrwx 2 root root 4096 Sep 13 10:18 tftpboot ... [root@chl1 /]# ls -la tftpboot/ drwxrwxrwx 2 root root 4096 Sep 13 10:18 . drwxr-xr-x 25 root root 4096 Sep 13 17:48 .. -rwxrwxrwx 1 nobody nobody 1811552 Sep 12 10:28 c3500xl-c3h2s-mz. 120-5.WC17.bin -rwxrwxrwx 1 nobody nobody 1181 Sep 13 17:51 pippo.config (pippo.config = fake file) This is what I get at the TFTP client side: LabTI-Infra-3524XL-01#copy running-config tftp: Address or name of remote host []? 10.58.2.204 Destination filename [labti-infra-3524xl-01-confg]? TFTP: error code 1 received - File not found %Error opening tftp://10.58.2.204/labti-infra-3524xl-01-confg (Undefined error) LabTI-Infra-3524XL-01# LabTI-Infra-3524XL-01#copy running-config tftp: Address or name of remote host []? 10.58.2.204 Destination filename [labti-infra-3524xl-01-confg]? pippo.config !! 2327 bytes copied in 0.831 secs So, it means that the TFTP client can only *re-write* an existing file but not creating new ones, and this is the expected behavior if the "-c" parameter is omitted! What am I missing? Any suggestion really appreciated! TIA, Davide

yum proxy username with @ character
by David Toman 14 Sep '07

14 Sep '07

Hi, I am having problem with setting up the proxy for yum correctly. I have got no influence on proxy policy or authentication methods. The proxy username contains the '@' character. My question is if there is any way how to enter the username correctly into the yum.conf. I tried many ways but has not been successful yet. Many thanks, David

Bypassing firewall alternatives
by Wei Yu 14 Sep '07

14 Sep '07

Hi I am experiencing a problem of bypassing firewalls. I know that "ssh -R" can forward ports from remote server to local ports. But it requires an account of the remote server, which seems to be a security hole. I am looking for other programs which can do so, any suggestions? Thanks.

NFS and iptables issues
by Chuck Campbell 13 Sep '07

13 Sep '07

I've got a newly installed Centos 5.0 box, planned to replace an ageing server (solaris box). I've set up the nfs shares, but the other solaris boxes won't mount them, unless I turn of iptables on the Centos box. If I do that, they mount, and all operations tested to date work fine. Iptables is allowing the 2049 tcp and udp ports already. What else needs to be opened up in iptables for nfs to work through the firewall? I looked at the RHEL system admin guide on NFS and found nothing useful. thanks, -chuck
