Re: [gentoo-user] Can't ping remote system
On 01/09/2013 20:50, Grant wrote: My laptop can't ping my remote system but it can ping others (google.com, yahoo.com, etc). I've tried disabling my firewall on both ends with '/etc/init.d/shorewall stop shorewall clear'. Could my ATT business ADSL connection on the remote system be blocking inbound pings? I did 'traceroute -w 30 -I ip-address' several times and the last IP displayed is always the same. I looked it up and it's an ATT IP supposedly located about 1500 miles from my machine which is also on an ATT connection. Does this tell me anything? Yes, it tells you that all hops up to that point at least respond to the kinds of icmp packets traceroute uses. The first hop that fails to answer isn't answering. You are looking for possible reasons why icmp might not be working out properly - that router is your first suspect. Admittedly, it might be blocking traceroute pings and still allow the responses you seek, but you have to start somewhere :-) So the culprit is the first IP that should appear in the list but doesn't? If so, how is that helpful since it's not displayed? This is where it gets tricky. You identify the last router in the list for which you have an address or name, and contact the NOC team for that organization. Ask them for the next hop in routing for the destination address you are trying to ping and hope that they will be kind enough to help you out. Oh man that's funny. Really? Let's say they do pass along the info. Then I hunt down contact info for the culprit router based on its IP and tell them their stuff isn't working and hope they fix it? Actually, since the last IP displayed is from ATT and my server's ISP is ATT, I suppose it's extremely likely that the culprit is either an ATT router somewhere or my own server and I could find out by calling ATT. Well, I did try to convey a sense of what it sometimes takes to deal with such things. Usually your ISP deals with it for you and you'd be amazed how often they pick up the phone to do exactly what I described. But I think this is getting OT to your actual problem. ATT's routers are probably not the cause, it only came up because of issues with pinging things, and that is not what you are trying to solve. -- Alan McKinnon alan.mckin...@gmail.com

[gentoo-user] systemd and LUKS
Hey list after the many discussions here about systemd I had a flash of objectivity (“Who cares if people rant about Lennart, the concept seems sound and I don’t care about separate /usr”). So I wanted to try systemd on my netbook. I cloned the / partition from sda2 to sda7 and chrooted into it. In there I followed the systemd Gentoo wiki¹, i.e. I configured the kernel, installed systemd, added -consolekit systemd to my use flags, rebuilt world with --new-use and added init=/usr/lib/systemd/systemd to the kernel cmdline. Rebooting works until the point of mounting /home, which is a LUKS container. I get the message: A start job is running for dev-mapper-home.service and eventually a timeout and prompt for root password or Ctrl-D. The wiki references a bug report that /etc/crypttab was ignored. Well, I didn’t have one, but apparently my old crypt setup was heeded (because systemd knew that I wanted sda5 mounted as home). I tried researching the problem. One I found was a Gentoo forum thread about LVM. I found out that I was missing CONFIG_DM_UEVENT. But enabling it didn’t help either. I found files in the partition’s /dev directory, which hinted that DEVTMPFS_MOUNT was not set. But I don’t suppose that’s really a problem. Does any of you have experience with this combination and would like to share it? Thanks. ¹ http://gentoo-en.vfose.ru/wiki/Systemd On a sidenote, for some reason, grub2 doesn’t find the kernel if I keep the menuentry’s search commands which are created by grub2-mkconfig.

It then boots the systemd installation on sda7 which was detected by os_prober. -- Gruß | Greetings | Qapla’ Please do not share anything from, with or about me with any Facebook service.

Let's say they do pass along the info. Then I hunt down contact info for the culprit router based on its IP and tell them their stuff isn't working and hope they fix it? Actually, since the last IP displayed is from ATT and my server's ISP is ATT, I suppose it's extremely likely that the culprit is either an ATT router somewhere or my own server and I could find out by calling ATT. Well, I did try to convey a sense of what it sometimes takes to deal with such things. Usually your ISP deals with it for you and you'd be amazed how often they pick up the phone to do exactly what I described. But I think this is getting OT to your actual problem. ATT's routers are probably not the cause, it only came up because of issues with pinging things, and that is not what you are trying to solve. +1 on Alan's hunch. I have not used Squid to comment on the specifics and also Grant stated that another proxy gave him similar symptoms. From my limited knowledge a proxy could be stalling because of cache configuration problems, like running out fs space, or inodes and also running out of memory if it has to process simultaneous requests from too many clients at a time. If the problem also manifests when the clients are within the same subnet, then this is unlikely to be a network issue. If all other causes are eliminated then a network related problem could be associated with TCP Window Scaling - but this would primarily show up on the transmission of larger files. This is why I initially asked if the problem shows up on video/audio downloads rather than small web pages. It's probably OT describing this problem here (Google can do it much better) but a quick test would show if this solves the problem: echo 0 /proc.sys/net/ipv4/tcp_default_window_scaling Please check the man page because this key may have changed over time and indeed it may not be a problem in later kernels who may have been coded so as to compensate for dodgy routers. This will slow down the connection because a smaller window size will be used, but there shouldn't be a problem of oversized packets being dropped by a misconfigured router on the way.

Thanks. ¹ http://gentoo-en.vfose.ru/wiki/Systemd On a sidenote, for some reason, grub2 doesn’t find the kernel if I keep the menuentry’s search commands which are created by grub2-mkconfig. Only if I remove all the search --uuid...yadda yadda..., the entry boots. The boot partition (where the grub files lie) is still my normal / on sda2. It then boots the systemd installation on sda7 which was detected by os_prober. Are you sure it's not under the advanced submenu? One question: how is the /etc/fstab file in the systemd installation?

The FS is ext4. Since the system hangs for unknown reasons several times Does it hang at a predictable point, like during boot, or poweroff? I know almost nothing about SD cards (yet). Do they develop bad blocks like other storage media? I notice fsck.ext4 has a -c flag to check for bad blocks. No, it hangs while compiling or while updateing (eix-sync; emerge ...). I did the following now: I did a binary image backup with dd of the sdcard. I made a backup of the all files from the bad fs with tar. I say YES to fsck to fix what it found. I made another backup of the all files from the bad fs with tar. I md5summed both tar archives and found them identical. Now...is the conclusion correct, that the identical md5sum indicate, that the fixed error of the fs only had impact to already invalidated data? Or whatelse could this indicate? Best regards, mcc PS: What come mind just in this moment: Can I ran fsck on an binary image of the fs which I made with dd somehow? Have you run out of inodes? - ext 4 has had very mixed success for me on solid state. Running out of inodes is a real problem for gentoo on smaller SD cards with standard settings. BillK Does this error message from fsck indicate that? I am really bad in guessing what fsck tries to cry at me ... ;) solfire:/rootfsck.ext4 -f -p /dev/sdb2 rootfs: Inodes that were part of a corrupted orphan linked list found. rootfs: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) [1]18644 exit 4 fsck.ext4 -f -p /dev/sdb2 Is there any way to correct the settings from the default values to more advances ones, which respect the sdcard size of 16GB *without* blanking it...a correction on the fly so to say??? And if not: Is there a way to backup the sdcard and playback the files after reformatting it by preserving all three time stamps of the files (atime is deactivated via fstab though) ? Best regards, mcc df -i - if you get 100% iUSE or near to it thats your problem ... I have seen that error message you give as a result of running out of inodes corrupting the FS. No, your only way out is to copy (I use rync) the files off, recreate the fs with max inodes (man mke2fs) and rsync the files back. Once an ext* fs has been created with a certain number of inodes its fixed until you re-format. I get it happening regularly on 4G cards when I forget and just emerge a couple of packages without cleaning up in between packages. On 16G cards, its compiling something like glibc or gcc that uses huge numbers of inodes at times. On a single 32G card I have, the standard settings have been fine ... so far :) Billk df -i gives the following: rootfs 971040 352208 618832 37% / /dev/root971040 352208 618832 37% / devtmpfs 63420434629861% /dev tmpfs 63456389630671% /run shm 63456 1634551% /dev/shm cgroup_root 63456 6634501% /sys/fs/cgroup /dev/mmcblk0p10 00 - /boot You mentioned rsync to backup... I used sudo tar cvf backup file root of embedded system the rootfs has only one partition... Is it alos ok to use tar or is there any drawback? Best regards, mcc There are some parameters for creating a better backup archive using tar, like --same-owner and --atime- preserve. By the way, it would be an interesting project to export some folders on your home computer using nfs, tuneling it through ssh, monting it locally in your embedded computer, and applying an unionfs to the rootfs. Just dreaming, of course. Góod luck Francisco Hi Francisco, as I understand the man page, --same-owner is only activ while extracting a tar: --same-owner create extracted files with the same ownership while extracting I always use --preserve like --preserve-permissions plus --same-order . Atime setting is disabled via fstab on my embedded system for two reasons: Performance wise since any access to a file will trigger a write action to the flash

Then, all I'd have to do is move it into /boot along with the new kernel (just like I do now), with *nothing* else required, and the kernel would call it, and things would just work (as long as it was there and I didn't forget to copy it to /boot). This exists. You can built initramfs right into the kernel. I've been doing it here for quite some time. You just tell the kernel either: * where to find a filespec so it knows what to include in the initramfs * what directory contains everything you want in the initramfs and then the kernel builds is and attaches it to itself during 'make' It's actually pretty trivial -- Douglas J Hunley (doug.hun...@gmail.com mailto:doug.hun...@gmail.com) Twitter: @hunleyd Web: douglasjhunley.com http://douglasjhunley.com G+: http://goo.gl/sajR3 I tried that a while back.

After it booted the kernel You may not know dynamic kernels as Linux is a static kernel that just may load additional modules _after_ it mounted the root fs.
