[gentoo-user] Dhclient and buggy ISP
Hey I have a following with Telia ISP and their dhcp-server... I'm using dhclient to get dynamic IP from ISP and also to update DDNS. When dhclient does DHCPDISCOVER the ISP will issue a new lease for 43200 sec after a normal DHCPOFFER, DHCPREQUEST and DHCPACK cycle; and the interface gets bound to the given address. Now when the dhclient does a subsequent DHCPREQUEST, server will issue DHCP with a declining lease-time ending at the same time as original 43200s lease. By releasing the lease and doing a new DHCPDISCOVER the lease time is reset to 43200s. The ISP how ever keeps track of the MAC and will always issue the same IP. When the lease-time of 43200 runs out the default gw stops responding and the internet connection dies. The only way to then get it to work is to manually start a new discover cycle (ifdown - ifup). I would like to configure the interface so, that there would not be an interuption in network traffic! Because the IP doesn't change, I would like to configure the WAN interface to stay up with the IP all the time and get dhclient to do DHCPDISCOVER to the ISP to update ISP-firewall to let the traffic through for the next 43200 sec. If the IP changes for some reason, I would like the dhclient to update the WAN interface. Would there be a ready way in Gentoo to achieve this? Or anyway :'D Ps. I hate my ISP :( Pps. I have other problems too... -- -Matti

I checked the permissions for iscan-data & they seem ok. No, I've never tried to use Selinux. However, I've just escaped fr another beast, ie Linux Mint 19 : DON'T try to install it alongside Gentoo !! This beast leads you along to a point where you've told it where to install -- a partition on my HDD (sdb5) -- , you click 'proceed' & it chugs along nicely for some time, then it says it's trying to install a bootloader without asking whether you want it to or where to do it. Next, it says it's failed to install Grub -- which I've never used -- , offers several ugly-looking options & freezes. All you can do is a hard power-off & when you restart, instead of the regular Lilo box of options, there's only a Grub prompt. Disaster looks you in the face ! SystemRescue to the rescue : Gentoo /boot is unaltered, so copy lilo.conf into the SR /etc dir, edit it to use SR paths, mount the Gentoo /boot , run 'lilo' & the MBR is restored to what it sb. Reboot & the familiar Lilo screen appears ! I wanted to see whether the latest Mint found my scanner, which would suggest that the problem doesn't involve the kernel, at least. I'm not trying again ! On inspection, Mint 19 does seem to have installed itself on /dev/sdb5 , so I can copy the vital files from its /boot to my own Gentoo /boot , edit lilo.conf accordingly & see if it will start : not today ! Next up -- too late for today -- is to see if I can get Nvidia working with an earlier kernel : at present it isn't. Then I can find out if Xsane can find my scanner with another kernel. Can anyone take a look at my Strace output ( 3 files), which is at http://chass.utoronto.ca/~purslow/test ? That would be a real help. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

I have successfully booted into Mint 19 -- it installed fully before it did its dirty MBR trick -- , so I can see what happens with Xsane tomorrow. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca
[gentoo-user] Computer keeps crashing during boot, need dmesg
Hi all, I'm having all sorts of trouble getting a new computer to boot. I have two NVME thingies in it with one containing Win10 and the other, eventually, Gentoo. I use Refind to control the booting with the machine using UEFI. The graphical front end to Refind boots fine and allows me to in turn boot Windows. It also spots and then allows me to boot a copy of SysrescueCD that I left plugged in. No joy with Linux. I get up to where the kernel appears to be doing something with sata and then it crashes. Now herein lies the problem. Is there a way to get dmesg logged to a file so that I can see what's actually failing? I need to be able to get back into the machine with SysrescueCD, which is no problem, and then have a look at the dmesg output to see what's going wrong. Does anyone have any idea as to how to do this, or another way of doing the debugging I'm trying to do? The stuff I've found on the web assumes that some of the loggers are working and can do stuff, I'm not getting to the stage where they have started up yet. I'm in the process of transferring from a non EFI hard disk setup to EFI & nvme. The hard disk based system boots with no problems. Assuming that the hard disk system and the nvme system will give nearly the same dmesg, looking at the hard disk dmesg, I see that if I go to where I think is the same posi as the crash on the nvme, is where it attempts to mount root: VFS: Mounted root (jfs filesystem) readonly on device 8:19. If I have managed to do something wrong with respect to this mounting, would it cause the crash or just complain and freeze? Any thoughts on this would be greatly appreciated, Andrew

I have a recollection reading someone, somewhere saying that something needed to be set in fstab if using jfs as root. Andrew

Many an installation were hosed lately because of a GRUB problem in Mint and potentially *buntu. Testing before releasing was not as thorough as it should have been: https://blog.linuxmint.com/?p=3620 -- Regards, Mick signature.asc Description: This is a digitally signed message part.

I have other problems too... I am not familiar with dhclient, although whenever I used it in various distros it just worked. Have you tried using dhcpcd instead? -- Regards, Mick signature.asc Description: This is a digitally signed message part.
