login error

Inconsistency detected by ld.so:dynamic-link.h:62: elf_get_dynamic_info:
Assertion '! bad dynamic tag"' failed

this is the message I get after I type something at the login: prompt (it doesn't bother to prompt the second line, the one with the password:)

the machine is a slackware 8.0 2.4.18 kernel patched for htb which acts as a router (and nothing else) for a /27 subnetwork (additional processes are portsentry and snmpd, i.e. it has a very small load)

the machine still works and I believe (haven't tried yet though) I can login via ssh

what could cause this problem and can it be repaired ?

thanks,

petre

Although I don't know how that can happen in a brand new installation, the error means, IMHO, that your login is linked (dynamicaly) with a differenet libc, incompatible with your dynamic linker (ld.so). The dynamic linker comes with glibc.

Did you install or upgrade from a previous version?

PS. This just came up to my mind: the usual tactic of crackers/script kiddies is to replace various executables in the attacked system. One of them is login. There is a small possibility that someone tried to replace your login with a new one (compiled in another system). You can verify this by checking the timestamp of /bin/login.
