Meme: Sólo se debe/puede enviar e-mail desde una IP fija. De acuerdo a mi experiencia, la mayoría de los servidores SMTP _sí_ acepta correo desde direcciones dinámicas. Existen numerosos servidores que no lo hacen, pero no son la mayoría en ningún caso. En particular, hotmail, que fue el sitio que dio origen al hilo, sí acepta correo proveniente de direcciones dinámicas, independientemente de que en el caso particular tratado la IP del colistero, aparentemente, estaba sujeta a filtros adicionales por otras razones. Estupendo. Tendríamos entonces un SMTP capaz de enviar correos a un dominio sí, a otro dominio no. No es estupendo en absoluto, pero es la dura realidad, como lo atestiguan mis configuraciones de servidores SMTP que parecen espagueti por el número de rutas especiales que tengo que meter para darle la vuelta a los obstáculos. Y este no es un problema sólo de los servidores con IPs malditas (dinámicas y etc.), aunque es mucho más doloroso si es el caso. Hablas de tu experiencia personal. Bueno, en la mía los correos eran frecuentemente rechazados por estar en alguna lista anti-spam. Lista a la que tenía el dudoso honor de pertenecer _sólo_ por tener una IP dinámica. No es un meme, es un problema con el que ya me he enfrentado. Es más, ya con IP fija, he tenido que solicitar la baja varias veces de diferentes listas porque el rango de IP fijas de mi proveedor estaba incluido en otro mayor de dinámicas o porque el mismo proveedor únicamente consideraba como válidos los correos que circulaban por sus servidores, excluyendo los de sus abonados. Y esto a pesar de tener un dominio perfectamente válido y registrado del que no ha salido ni un solo correo basura. Pues tenemos la misma experiencia, excepto que yo ya me aburrí hace tiempo de andar rogándole a los administradores de RBLs y sus, muchas veces arbitrarias, políticas, y prefiero darle la vuelta a los obstáculos creando rutas alternativas. Lo que pasa es que he visto que una respuesta casi estándar a la gente que quiere montar su propio servidor SMTP es No lo hagas. Envía tu correo mediante tu ISP que lo va a tratar mejor. No digo que no haya problemas, los hay a montones, pero eso dista mucho de afirmar que casi todos los servidores SMTP van a rechazar mensajes desde IPs dinámicas. En mi experiencia, no siendo pocos los que lo hacen, no son ni con mucho la mayoría. Mi preocupación es que el meme se propaga y los usuarios legítimos del protocolo caen en la misma bolsa que los spammers. Es una táctica de desprestigio archiconocida pero que sigue dando

From everything I can find it appears that the graphics controller on these motherboards (mine has the C15G nVidia chipset and the controller is recognised as a GEForce 6100). I followed Jim Perrin's instructions and downloaded and installed the nVidia driver from RPMForge and still have the same problem. My next step is to try to find a PCI or PCI express graphics card that is supported by Linux so that I can start using this server. The subject of the thread in which my problems were discussed is: nVdia C15G chipset and GeForce 6100 on board graphix controller Sorry that I cannot give you more positive feedback but hope that this helps in some way.

[CentOS] Performance Issues
My apology for cross posting We have a DELL6850 with 8Gbytes of memory, four 3.2Ghz CPU's , perc 4 raid controller, with fourteen 300Gbyte 10Krpm disk on a powervault 220s, And a powervault 124T LTO-3 tape systems on a separate 160Mbyte/sec adaptec SCSI card. The disks are configured as two 2Tbyte raid 0 partitions using the perc 4 hardware. The problem is - reading from the disk, and writing to the tape is pathetically slow. The specs say I should get around 80Mbyte/second - in reality - is about 500 Kbytes/second Writing just to tape, using /dev/zero as input and dd to write, I can get up to 60Mybte/second, indicating that the tape drive and scsi card is functional from a hardware perspective. Since I can read and write data to the disks - I assume that they are functional. The files are 80Mybtes for the minimum size that I am writing to tape. DELL Support hides behind the fact that CENTOS is not a supported OS, But RED HAT is - so switch to it, so DELL can get RED HAT Support involved. And the fact that Rocks is a modification to an unsupported OS I have tried using various block size in tar from 256 to 8192 - with minimal success. Does anybody have any experience on setting the OS/Kernel parameters to utilize the hardware at something more then a snails pace? Or Suggestions on what I could test and/or try?

Two errors are apparent. One may be difficult to correct. As you originally discovered, the user ID is being change during execution of the command to change a group. And it is using the ID from the symbolic link owner, as you later noticed. The 2nd bug is a recursion into the original directory via the symbolic link when dereference is not suppressed. IMO, recursion should not occur, but I know from a programming background that it takes a little foresight, thought and intense effort to avoid this sort of trap. As an afterthought, how valid is it to have user control files that are supposed to be contained in an invisible directory in the user's $HOME?
