[CELS Sysadmins] Visitor net registrations on desktop net
by Leggett, Torrance I. 30 Oct '14

30 Oct '14

This is something that needs to be fixed ASAP since it's causing a good deal of grief for us and our users. On our setup we had a shared network between 140.221.10.0/23 and 130.202.17.0/24 where if you were plugged in and had a static IP on the 140.221.10.0/23 network you would get that IP otherwise you would get assigned a dynamic IP out of our visitor net space (and be required to register and all of that): shared-network "DesktopNet" { subnet 140.221.10.0 netmask 255.255.254.0 { filename "pxelinux.0"; next-server 140.221.8.88; option subnet-mask 255.255.254.0; option broadcast-address 140.221.11.255; option netbios-name-servers 140.221.9.66; option netbios-node-type 8; option routers 140.221.10.1; option option-140 "140.221.8.91"; deny unknown-clients; } #new visitor space subnet 130.202.17.0 netmask 255.255.255.0 { range 130.202.17.5 130.202.17.254; option subnet-mask 255.255.255.0; option broadcast-address 130.202.17.255; option routers 130.202.17.1; option domain-name-servers 140.221.9.6, 130.202.101.6, 130.202.101.37; } } Currently, users who have a registered MAC in IHW (for the most part) are getting IPs from the 140.221.10.0/23 range but unregistered users just get denied an IP. We need the shared network to work so unregistered users get a visitor IP. We also have the same issue for the following networks, though it's not as problematic for us currently: shared-network "I2U2" { subnet 192.5.186.64 netmask 255.255.255.192 { filename "pxelinux.0"; next-server 140.221.8.88; option subnet-mask 255.255.255.192; option routers 192.5.186.65; option domain-name "i2u2.org"; option domain-name-servers 140.221.9.6, 130.202.101.6, 130.202.101.37; server-identifier sirius.mcs.anl.gov; option broadcast-address 192.5.186.127; default-lease-time 28800; max-lease-time 28800; deny unknown-clients; } subnet 10.5.186.64 netmask 255.255.255.192 { pool { range 10.5.186.70 10.5.186.90; allow unknown-clients; option subnet-mask 255.255.255.192; option broadcast-address 10.5.186.127; option netbios-name-servers 10.5.186.66; option routers 10.5.186.65; option domain-name "guest.i2u2.org"; option domain-name-servers 10.5.186.66; server-identifier 10.5.186.66; default-lease-time 60; max-lease-time 60; } } } # End I2U2 vlan And because the 140.221.6.0/23 and 140.221.8.0/23 networks are on the same VLAN it should be done for them as well: shared-network "BorgNet" { # vlan808 serverNET subnet 140.221.8.0 netmask 255.255.254.0 { filename "pxelinux.0"; next-server 140.221.8.88; option subnet-mask 255.255.254.0; option broadcast-address 140.221.9.255; option netbios-name-servers 140.221.9.66; option netbios-node-type 8; option routers 140.221.8.1; option option-140 "140.221.8.91"; deny unknown-clients; } subnet 140.221.6.0 netmask 255.255.254.0 { filename "pxelinux.0"; next-server 140.221.8.88; option subnet-mask 255.255.254.0; option broadcast-address 140.221.7.255; option routers 140.221.7.1; option domain-name "mcs.anl.gov anl.gov"; } _______________________________________________ This is the CELS Sysadmins mailing list.

Re: [CELS Sysadmins] DNS diffs
by Leggett, Torrance I. 20 Oct '14

20 Oct '14

Hold off on this. It looks like there was a rare case where items got marked internal only for things that should be external. I'm working on uploading fixed records and having a re-run done. From: <Leggett>, Ti Leggett <leggett(a)mcs.anl.gov<mailto:[email protected]>> Date: Monday, October 20, 2014 at 8:55 AM To: CELS Admins <sysadmins(a)lists.cels.anl.gov<mailto:[email protected]>> Subject: [CELS Sysadmins] DNS diffs I have the latest set of zone files from Gene between what's in IHW and in DNS. Can everyone go through them to see what things need fixing before Wednesday? The files are in Gene's home directory: ~rackow/IHW-DNS-Oct-17-2014.tgz And this is how I'm goingin through them: diff -u -r DNS IHW-prod/external | egrep -v '^-.* in mx .*' | less If you see things like mgmt and power controller and the like disappearing from there, verify they're being added to IHW-prod/internal, since those are the few types of things I did mark internal only in the migration. _______________________________________________ This is the CELS Sysadmins mailing list.
