Re: [gentoo-user] Re: Changing glibc
No other diff program comes even close to BC in terms of diff output quality and merge capability. I am willing to go through much more hoops than this just to be able to use this under linux. And also, to avoid any misrepresentation, their support in determining the cause of the issue was very good. The problem seems to be that their linux build is using an older gcc version. This was causing an ABI related crash in the strstr function, which was using SSE instructions. So at some point, they will probably switch to a newer compiler and the problem will go away. But if I mail their support, it would take many messages until we come to the same page (the previous developer getting copied on it, he remembers the issue etc etc). It is much faster to just try it :) -- Timur
[gentoo-user] Changing glibc
Hi, I am using a closed source software package on my 64 bit gentoo linux system. The software package is beyond compare by scooter soft. Because of the way this package is built, it needs a specially patched version of glibc. I have patched my existing glibc version (2.18) and have been avoiding updating my glibc since. Now I am wondering whether the latest update of bcompare will work with the latest glibc (2.19). So, if I upgrade to 2.19 and the package doesn't work, how can I go back to the working, patched 2.18? I know that portage issues the most scary warnings when you try to downgrade glibc. So what does the community recommend? -- Timur
Re: [gentoo-user] Changing glibc

[gentoo-user] Forwarding bug in kernel 3.14.1 and 3.14.2
Hi, To all folks that use their gentoo linux PC as their internet router/gateway, don't upgrade your kernel to 3.14.1 or 3.14.2. These versions have a bug related to IP packet forwarding. Internet upload speed for the NAT clients gets extremely slow (in the order of 10Kbps), which download speed remain unaffected. I have spent the entire weekend trying to debug the slow upload issue. I tried different NIC's, different cables, different clients etc, problem was still occurring. Upload/download from the Gentoo linux PC is fine, but any NAT client exhibits the slow upload speed problem. I also suspected that somehow the MSS clamping with iptables doesn't work, that wasn't the problem either, because even with all tables flushed and only IP MASQUERADING in place the problem was there. I finally found a bug report that explains the symtom: http://www.spinics.net/lists/netdev/msg280571.html I then downgraded the kernel to 3.13.11, which fixed the problem. So, all of you guys using your Gentoo PC as your internet gateway, keep 3.13.11 around for a while. -- Timur
[gentoo-user] VPN question
Hello everybody, I have a gentoo linux PC at home that I am using as my internet gateway. It is also running a web server and a mail server with a static IP. Everything is working fine. Now I have installed a VPN server on this system (OpenVPN) and I am using a VPN service provider to get a USA IP address. This, in its own, works fine as well. But once I bring up the VPN tunnel, the web server and the mail server become unavailable. So, I need a way to have both the VPN tunnel and my web/mail servers available simultaneously. I think some ip routing magic is required to accomplish this, but all my experiments so far didn't yield any result. I would appreciate if somebody can put me in the right direction for finding a solution. -- Timur

The VPN service provider is http://www.strongvpn.com and they have servers all over the world. I am using their server located in New York. Once I establish the SSL VPN tunnel, the NY server effectively becomes my internet gateway. I need to do this to get around websites that impose geographical restrictions on their service (example, netflix.com, pandora.com).

Regarding IP address, do you mean the USA IP address I receive from the VPN service provider or my ISP assigned static IP? Timur

[gentoo-user] creating overlay to modify net-fs/samba-3.6.18
Today I had quite a bit of issues while creating a local overlay to
modify samba. Got through all of them, but there were the following
issues which I wanted to bring up, because I am not sure whether I have
done anything wrong:
- I had created the overlay under /root/overlay, but this is causing
permission denied errors from ebuild when creating the Manifest file:
==
/usr/lib64/portage/bin/ebuild.sh: line 545:
/root/overlay/net-fs/samba/samba-3.6.18.ebuild: Permission denied

* Working directory: '/usr/lib64/portage/pym'
* S: '/var/tmp/portage/net-fs/samba-3.6.18/work/samba-3.6.18'
==
After trying many different things without luck, I tried using
/usr/local/portage as the overlay folder and the problem went away! So
my first question is, does ebuild have a special security feature which
prevents it from processing overlays under /root ?
- The second issue is eclass related. After I moved net-fs/samba under
/usr/local/portage, I got the following error during Manifest creation:
==

[gentoo-user] configuring NFS server to handle client reboots
Hi, I am using Gentoo Linux as an NFS server while doing development on an Blackfin embedded system. The Blackfin is running uClinux and the development host is Gentoo testing version (~amd64). The NFS server version is 1.2.7. Here is the problem that I am observing: I start from a known state, restarting the NFS server on Gentoo and power cycling the Blackfin. Once the Blackfin system has booted, I mount an folder on the Blackfin. This succeeds without any problem. Then I power cycle the Blackfin again and after it is up, I try to mount that same folder again. But this time, the mount command hangs for a minute or so and eventually fails with a timeout error. Here is the mount command: mount -o nolock,tcp 10.2.2.254:/romfs_2011R1 /mnt When I look into the NFS server's system log, I can see that the mount was authenticated: Jun 30 13:54:53 bonsai rpc.mountd[1597]: authenticated mount request from 10.2.2.220:911 for /home/ta/uclinux_2011R1/db1/uclinux-dist/romfs (/home/ta/uclinux_2011R1) I have captured what is happening using wireshark and what I am seeing is that the mount request succeeds, but the client initiates another TCP connection (SYN) and this SYN is never responded to by the server. I know that a sm-notify program is used on both NFS clients/servers to notify reboots, but this embedded system does not have the sm-notify capability. And I would rather not try to port it to uClinux. So, my question is, can I somehow configure the NFS server to allow mounting the same directory repeatedly whenever the NFS client reboots? -- Timur

Also, when using TCP, if I restart the NFS server on the gentoo host, /etc/init.d/nfs restart Then I can mount the NFS share on the Blackfin repeatedly. This all tells me that the NFS server is preventing subsequent TCP mounts unless the existing mount is unmounted first. -- Timur

[gentoo-user] Weird hibernate problem
After corrupting my gentoo root filesystem system during hibernate experiments, I have finally finished the reinstallation. But hibernate still doesn't seem to work correctly. The symptoms are the same as during the experiments leading to the root fs corruption, but this time the root seems to remain intact. Here is what happened during the first experiment. I had an 8G swap partition as /dev/sda5 and a data partition as /dev/sda6. Thinking that pm-hibernate requires a dedicated, separate partition, I backed up /dev/sda6, turned off swap at /dev/sda5, deleted /dev/sda[56] and then created /dev/sda5 (8G), /dev/sda6 (8G) and /dev/sda7 (remaining size) Then I specified /dev/sda6 as the resume partition on the kernel command line. But when I did the pm-hibernate, the system powered off, and after reboot, the system seemed to have restored itself to the state it was at when I ran pm-hibernate. So it seemed to have worked, but the system was strangely unstable. There were many filesystem errors in the root partition and when I did a ps ax, I saw hundreds of kworker kernel threads lingering around. It was as if the hibernate image was slightly corrupted, but not enough to cause a complete lockup, but enough to cause there strange symptoms. I first thought this was related to using the swap partition as the resume destination. But after reinstalling gentoo, I again used a separate partition for hibernate, but I am still seeing the same symtoms. Many kworker kernel threads are sleeping. But this time, the root filesystem didn't have any error. Concerned that a filesystem corruption is imminent, I immediately turned off power. So, what could be causing these strange problems? Based on what I have read so far, the resume partition needs to be an active swap partition. This seems rather strange, because linux is using the swap partition for memory management as well.

I have just tried again using pm-suspend and the same thing happens. Everything looks like it has worked, but when I do a ps ax, there are many (currently around 50) sleeping kernel threads. There are also a few extraneous migration, ksoftirq threads intermixed. -- Timur
Re: [gentoo-user] Weird hibernate problem
One unusual property of this system is that it has 5 additional SATA disks to be used for RAID experiments, in addition to the disk holding gentoo. So there are a total of 6 disks. But during these experiments, these 5 additional disks are not mounted. The motherboard is an Asus P8V68Z-VPRO/GEN3 with 8G RAM and a i7-2600K CPU, running 32bit gentoo. There are no peripherals attached to any of the motherboard expansion slots. -- Timur
[gentoo-user] Preventing a package from being updated
Hi, I am using the ~x86 (testing) version of gentoo linux. After recent updates, my X windows became extremely sluggish and I found out that the problem is related to a new version of mesa (7.8.2 specifically). So I downgraded to version 7.7.1 and my desktop works great again. Now I want to prevent mesa from being updated until this issue is sorted out upstream. I have looked at package.provide, but that didn't work. Currently, I have placed media-libs/mesa into my /etc/portage/package.mask file and this seems to do the trick. Is this the recommended way for handling this situation? Being a long time gentoo user, I want to do things the right way, so just working fine isn't enough :) -- Timur

I think it was the upgrade to net-dns/openresolv-3.3.2 which was responsible. The solution was to edit etc/resolvconf.conf and uncomment the line name_servers=127.0.0.1 That's what I tried yesterday and it resolved the problem. So it seems the new resolver does not default to checking localhost as a dns server and needs to be explicitely told to do so... -- Timur

[gentoo-user] Building all packages except gcc
Hello, How would I go about rebuilding all installed packages, except gcc? I suppose I could do emerge --emptytree world, but that would also merge gcc, which I don't want, because I want to be sure that the whole system is rebuilt with the same compiler. Any help is appreciated... -- Timur Aydin -- [EMAIL PROTECTED] mailing list
[gentoo-user] Wireless PCMCIA card issue with 2.6.18 linux kernel
Hi, I have a Senao NL-2511CD PLUS EXT2 wireless PCMCIA card, which I am planning to use in my desktop PC through a Ricoh RL5c475 PCI-PCMCIA bridge.

[gentoo-user] glibconfig.h missing
Hi, I have tried to compile a library that uses glib-1.2 and the configure script of the library failed. Looking at config.log, I saw that the glibconfig.h file can't be found. Indeed, the /usr/include/glib-1.2/glib.h file includes glibconfig.h, which doesn't exist anywhere on my system. I have extracted glib-1.2 and ran the configure script, and the glibconfig.h was generated. Once I copied this file into /usr/include/glib-1.2, the problem was resolved. Is this a bug or is it a misconfiguration of my system? -- Timur Aydin -- gentoo-user@gentoo.org mailing list
