hallo, seit zwei Tagen sind meine Clients beim Aufbau von Internetverbindungen sehr langsam. Ich kann mich nicht erinnern, irgendetwas am Server verändert zu haben. Egal was ich aufrufe, ob Mail oder Websites, es dauert eine Weile, bis die Seite erscheint, bzw. die Mails abgeholt werden. In der /var/log/messages (server) ist nichts für mich Auffälliges zu sehen. Wo sollte ich anfangen zu suchen? server -suse 9.0 2 clients - suse 9.0 provider -t-com ein ping auf dem Server wird sofort angezeigt, die Verbindungszeiten sind im ms-Bereich (ca. 60 ms) ein ping auf dem Client wird sehr verzögert angezeigt, die Verbindungszeiten sind aber vergleichbar (auch so um die 60 ms) zum Server und doch dauert es "ewig", bis die Daten erscheinen (5 pings in 20 sec.) Wo muß ich suchen? Danke. christian

Hallo Christian, Martin und alle Anderen in so einem Fall kann es immer hilfreich sein, die Zeiten eines ping auf den Namen eines Rechners und den ping auf eine IP_Adresse in Dot-Notation zu vergleichen. Also statt 'ping pglin01.whereever.whatever' einen 'ping 198.208.140.20' abzusetzen. Wenn im zweiten Fall eine Antwort sofort kommt, oder auch eine Fehlermeldung ala 'host unreachable' oder 'network unreachable' sofort kommt, dann bestehen immer gute Gründe anzunehmen, daß etwas mit der Namensauflösung (im Internet in der Regel DNS, im Windows-Netzwerk auch WINS) nicht stimmt. Da kann man dann auch mal mit einem Tool namens nslookup (für DNS, für WINS fehlt mir noch so ein Tool) Tests machen, ob Rechnernamen aufgelöst werden können.

Versuch mal ein 'strace ping', vielleicht kannst Du sehen, an welcher Stelle das Ping die Pause macht.
Opss, da kommt ja allerhand, aber anfangen kann ich damit nichts, kann mir vielleicht jemand die wichtige Stelle zeigen und sagen, was es bedeutet? ------- chr@kiste:~> strace ping www.suse.de execve("/bin/ping", ["ping", "www.suse.de"], [/* 63 vars */]) = 0 uname({sys="Linux", node="kiste", ...}) = 0 brk(0) = 0x8062548 old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40019000 open("/etc/ld.so.preload", O_RDONLY) = -1 ENOENT (No such file or directory) open("/etc/ld.so.cache", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=79653, ...}) = 0 old_mmap(NULL, 79653, PROT_READ, MAP_PRIVATE, 3, 0) = 0x4001a000 close(3) = 0 open("/lib/libresolv.so.2", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\0*\0\000"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=74600, ...}) = 0 old_mmap(NULL, 73640, PROT_READ|PROT_EXEC, MAP_PRIVATE, 3, 0) = 0x4002e000 old_mmap(0x4003d000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 3, 0xf000) = 0x4003d000 old_mmap(0x4003e000, 8104, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x4003e000 close(3) = 0 open("/lib/i686/libc.so.6", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\320]\1"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=1461208, ...}) = 0 old_mmap(NULL, 1256644, PROT_READ|PROT_EXEC, MAP_PRIVATE, 3, 0) = 0x40040000 old_mmap(0x4016c000, 20480, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 3, 0x12c000) = 0x4016c000 old_mmap(0x40171000, 7364, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x40171000 close(3) = 0 munmap(0x4001a000, 79653) = 0 socket(PF_INET, SOCK_RAW, IPPROTO_ICMP) = -1 EPERM (Operation not permitted) getuid32() = 500 setuid32(0x1f4) = 0 brk(0) = 0x8062548 brk(0x8083548) = 0x8083548 brk(0) = 0x8083548 brk(0x8084000) = 0x8084000 gettimeofday({1080801441, 776994}, NULL) = 0 getpid() = 3059 open("/etc/resolv.conf", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=60, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x4001a000 read(3, "domain local\nnameserver 217.5.11"..., 4096) = 60 read(3, "", 4096) = 0 close(3) = 0 munmap(0x4001a000, 4096) = 0 brk(0) = 0x8084000 brk(0) = 0x8084000 brk(0x8083000) = 0x8083000 brk(0) = 0x8083000 socket(PF_UNIX, SOCK_STREAM, 0) = 3 connect(3, {sa_family=AF_UNIX, path="/var/run/.nscd_socket"}, 110) = 0 writev(3, [{"\2\0\0\0\4\0\0\0\f\0\0\0", 12}, {"www.suse.de\0", 12}], 2) = 24 read(3, "\2\0\0\0\377\377\377\377\0\0\0\0\0\0\0\0\377\377\377\377"..., 32) = 32 close(3) = 0 open("/etc/nsswitch.conf", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=1239, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x4001a000 read(3, "#\n# /etc/nsswitch.conf\n#\n# An ex"..., 4096) = 1239 read(3, "", 4096) = 0 close(3) = 0 munmap(0x4001a000, 4096) = 0 open("/etc/ld.so.cache", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=79653, ...}) = 0 old_mmap(NULL, 79653, PROT_READ, MAP_PRIVATE, 3, 0) = 0x4001a000 close(3) = 0 open("/lib/libnss_files.so.2", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0p\35\0\000"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=42162, ...}) = 0 old_mmap(NULL, 38204, PROT_READ|PROT_EXEC, MAP_PRIVATE, 3, 0) = 0x40173000 old_mmap(0x4017c000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 3, 0x8000) = 0x4017c000 close(3) = 0 munmap(0x4001a000, 79653) = 0 open("/etc/host.conf", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=370, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x4001a000 read(3, "#\n# /etc/host.conf -

Hallo Christian, Martin und alle Anderen in so einem Fall kann es immer hilfreich sein, die Zeiten eines ping auf den Namen eines Rechners und den ping auf eine IP_Adresse in Dot-Notation zu vergleichen. Also statt 'ping pglin01.whereever.whatever' einen 'ping 198.208.140.20' abzusetzen. Wenn im zweiten Fall eine Antwort sofort kommt, oder auch eine Fehlermeldung ala 'host unreachable' oder 'network unreachable' sofort kommt, dann bestehen immer gute Gründe anzunehmen, daß etwas mit der Namensauflösung (im Internet in der Regel DNS, im Windows-Netzwerk auch WINS) nicht stimmt. Da kann man dann auch mal mit einem Tool namens nslookup (für DNS, für WINS fehlt mir noch so ein Tool) Tests machen, ob Rechnernamen aufgelöst werden können.
