iptables question
by Ray Leventhal 21 Sep '07

21 Sep '07

Hi all, With SELinux in permissive mode and iptables running, I'm unable to retrieve directory listings with ftp. stop iptables, and all appears again. This seems to be unrelated to passive/port modes for ftp client. If this is off topic, please let me know offlist and I'll take my question elsewhere. Otherwise I'll repost with output of # iptables status TIA, ~Ray

Chroot tool
by Jordi Espasa Clofent 21 Sep '07

21 Sep '07

Hi, Currently I'm working on building chroot environment for a several users. The needs of those users are different, so the binaries and their libraries are differents too. The building process tends to be so tedious. I'm using a odd script to automatize the copy of needed libraries, but it not works very fine. ¿Is there some tool to automatize the chroot jails creation/management? ¿Do you use some kind of shell-script? -- Thanks, Jordi Espasa Clofent

Maximum RPM has been posted to usenet as a compiled help file (CHM) the site http://www.rpm.org/max-rpm was recursively downloaded using >wget -m <url> FAR, by Helpware, was used to build the CHM (WinXP). GIMP (linux) was used to make the cover graphic. the NZB is here http://www.tlviewer.org/max-rpm.nzb To see which usenet group and grab with Pan, look inside the NZB. the command below can be used to fetch it >perl nzbperl.pl max-rpm.nzb nzbperl is here http://noisybox.net/computers/nzbperl/ if you need a x86_64 package for uudeview go here http://www.tlviewer.org/c5repo/web This was a nice one-day project. ps Does anyone know how to compile a CHM on Linux? I know a few chm clients on linux, but nothing that can build a CHM. regards, --------------------------------- Be a better Globetrotter. Get better travel answers from someone who knows. Yahoo!

But, that's a rosey concept! John: That happened to us, this week. I was unable to use the SMTP on my web site for somewhere between 48-67 hours, because of Spamhaus. Apparently, this morning, when my wife powered things up, we got a clean IP address. When I went to the Spamhaus web site, it showed the IP numbers clear, but, on other lists. Supposedly, if one uses SMTP Authentication, this problem goes away. However, I have always used SMTP Authentication. I do not want to change to another web hosting ISP, because this problem might follow me. And, I've been with them for almost 6 years. Also, Spamhaus says the problem should go away, in 1 or 2 hours, and in the past that was true, but not this time. Good for you, to want to handle this in a better way for your clients! Lanny

LDAP / PAM -- Invalid Credentials Error
by Von Landfried 20 Sep '07

20 Sep '07

Hello, I am having a small issue with LDAP, and I hope someone here might be able to provide a few tips. I am unable to authenticate as user 'testuser' on server 'storage' and the following errors appear in /var/log/messages on server 'storage' Sep 19 16:56:17 storage sshd(pam_unix)[3124]: check pass; user unknown Sep 19 16:56:17 storage sshd(pam_unix)[3124]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=test-kja1 Sep 19 16:56:17 storage sshd[3124]: pam_ldap: error trying to bind as user "uid=testuser,ou=People,dc=example,dc=local" (Invalid credentials) I am also unable to issue this command: # passwd testuser passwd: Unknown user name 'testuser'. but this command works fine: # finger testuser Login: testuser Name: Test User Directory: /home/testuser Shell: /bin/bash Never logged in. No mail. No Plan. The server 'storage' is the LDAP host server, and there are about 9 other servers configured to use 'storage' to authenticate users.

best source for rpmdevtools RPM in C5
by mark pryor 20 Sep '07

20 Sep '07

hello, I'm going to try this question again. The first time I botched it and the answers I got were useless. I want to use rpmdevtools to help with some packaging chores. There is no C5 version that I can find. I've located an SRC RPM in a location that is known to be C5 compatible. There are 2 versions of rpmdevtools: http://download.fedora.redhat.com/pub/fedora/linux/extras/6/SRPMS/rpmdevtoo… http://download.fedora.redhat.com/pub/fedora/linux/extras/6/SRPMS/rpmdevtoo… naturally I grabbed the highest version (6.1) and rebuilt it for EL5. The installation halted, missing a version of rpm-build higher than the base version in C5. It seems that rpm-build 4.4.2.1+ comes from FC7. This is the first time that I've seen an FC6 repo package that depended on something from FC7. rpmdevtools 5.3.1 builds, installs, and works fine on C5. I think I made the right decisions here (balking at trying to install a higher version of rpm-build). If you need to use rpmdevtools, how would you approach the problem? What source repo would you use? Is there an rhel5 SRC RPM? Where is it? thanks, Mark --------------------------------- Got a little couch potato? Check out fun summer activities for kids.

2 nics, 2 networks, 2 switches
by Kanwar Ranbir Sandhu 20 Sep '07

20 Sep '07

Hi Everyone, I have a server with two NICs. One NIC is already configured for network A, but the second is disabled at the moment. I want to enable it too, but put it on network B. Unfortunately, I don't know how to do that. Well, what I've tried hasn't worked anyway. Each NIC is plugged into a separate switch, and each network has it's own gateway. But, I can only set one default gateway. What parameters do I need to use in the NIC config file to force NIC 1 to use gateway 1, and NIC 2 to use gateway 2? I tried using "GATEWAY=blah" in each config file (ifcfg-eth0 and ifcfg-eth1), but it didn't work. I'm over looking something. Regards, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.22.2-42.fc6 i686 GNU/Linux 11:40:26 up 14 days, 10:05, 4 users, load average: 0.57, 0.20, 0.08
